1 SQL Reference Manual Notation Introduction Data Types Predicates Operators Expressions SQL Functions SQL Statements Restrictions for SQL Statements SQL Error Codes

1.1 Notation

This reference use BNF (Backus Naur Form) which is a notation technique used to define programming languages. BNF describes the syntax of a grammar using a set of production rules and a set of symbols.

Symbols used in BNF

Symbol Description

< > Angle brackets are used to surround the name of a syntactic element (BNF nonterminal) of the SQL language.

::= The definition operator is used to provide definitions of the element appeared on the left side of the operator in a production rule.

[ ] Square brackets are used to indicate optional elements in a formula. Optional elements may be specified or omitted.

{ } Braces group elements in a formula. Repetitive elements (zero or more elements) can be specified within brace symbols.

| The alternative operator indicates that the portion of the formula following the bar is an alternative to the portion preceding the bar.

SAP HANA SQL and System Views ReferencesSQL Reference Manual


Symbol Description

... The ellipsis indicates that the element may be repeated any number of times. If ellipsis appears after grouped elements specifying that the grouped elements enclosed with braces are repeated. If ellipsis appears after a single element, only that element is repeated.

!! Introduces normal English text. This is used when the definition of a syntactic element is not expressed in BNF.

BNF Lowest Terms Representations

Throughout the BNF used in this manual each syntax term will be defined to one of the lowest term representations shown below.

Supported Languages and Code Pages

The SAP HANA Database supports Unicode to allow the use of all languages in the Unicode Standard and 7 Bit ASCII code page without restriction.

Comment

You can add comments to improve readability and maintainability of your SQL statements. Comments are delimited in SQL statements as follows: Double hyphens "--". Everything after the double hyphen until the end of a line is ignored by the SQL parser. "/*" and "*/". This style of commenting is used to place comments on multiple lines. All text between the opening "/*" and closing "*/" is ignored by the SQL parser.

Identifiers

Syntax:

::= |

::= {|} [{ | | | | }...]

::=

Identifiers are used to represent names used in SQL statement including table name, view name, synonym name, column name, index name, function name, procedure name, user name, role name, and so on. There are two kinds of identifiers, undelimited identifiers and delimited identifiers. Undelimited table and column names must start with a letter and cannot contain any symbols other than

digits or an underscore "_". Delimited identifiers are enclosed in the delimiter, double quotes, then the identifier can contain any character

including special characters. For example, "AB$%CD" is a valid identifier name. Limitations:

"_SYS_" is reserved exclusively for database engine, hence not allowed at the beginning of schema object names.

Role name and user name must be specified as undelimited identifiers. Maximum length for the identifiers is 127 characters.

Single Quotation Mark

Single quotation marks are used to delimit string literals and single quotation mark itself can be represented using two single quotation marks.



Double Quotation Mark

Double quotation marks are used to delimit identifiers and double quotation mark itself can be represented using two double quotation marks.

SQL Reserved Words

Reserved words are words which have a special meaning to the SQL parser in the SAP HANA Database that cannot be used as a user-defined name. Reserved words should not be used in SQL statements for schema object names. If necessary, you can work around this limitation by delimiting a table or column name with double quotation marks.The following table lists all the current and future reserved words for the SAP HANA Database.

Datetime Types

DATEThe DATE data type consists of year, month, and day information to represent a date value. The default format for the DATE data type is 'YYYY-MM-DD'. YYYY represents the year, MM represents the month, and DD represents the day. The range of date value is 0001-01-01 through 9999-12-31.

TIMEThe TIME data type consists of hour, minute, and second to represent a time value. The default format for the TIME data type is 'HH24:MI:SS'. HH24 represents the hour from 0 to 24, MI represents the minute from 0 to 59, SS represents the second from 0 to 59.

SECONDDATEThe SECONDDATE data type consists of year, month, day, hour, minute and second information to represent a date with time value. The default format for the SECONDDATE data type is 'YYYY-MM-DD HH24:MI:SS'. YYYY represents the year, MM represents the month, DD represents the day, HH24 represents hour, MI represents minute, and SS represents seconds. The range of date value is 0001-01-01 00:00:01 through 9999-12-31 24:00:00.

TIMESTAMPThe TIMESTAMP data type consists of date and time information. Its default format is 'YYYY-MM-DD HH24:MI:SS.FF7'. FFn represents the fractional seconds where n indicates the number of digits in fractional part. . The range of the timestamp value is 0001-01-01 00:00:00.0000000 through 9999-12-31 23:59:59.9999999.

For details on supported formats for datetime types, refer to Table 4, Table 5, Table 6 and Table 7 below.Date FormatsThe following date/time formats can be used when parsing a string into a date/time type and converting a date/time type value into a string value. Please note that format for Timestamp is the combination of Date and Time with the additional support for fractional seconds.

Numeric Types

TINYINTThe TINYINT data type stores an 8-bit unsigned integer. The minimum value is 0 and the maximum value is 255 for TINYINT.

SMALLINTThe SMALLINT data type stores a 16-bit signed integer. The minimum value is -32,768 and the maximum value is 32,767 for SMALLINT.

INTEGERThe INTEGER data type stores a 32-bit signed integer. The minimum value is -2,147,483,648 and the maximum value is 2,147,483,647 for INTEGER.

BIGINTThe BIGINT data type stores a 64-bit signed integer. The minimum value is -9,223,372,036,854,775,808 and the maximum value is 9,223,372,036,854,775,807 for BIGINT.

DECIMAL(precision, scale) or DEC(p,s)DECIMAL(p, s) is the SQL standard notation for fixed-point decimal. "p" specifies precision or the number of total digits (the sum of whole digits and fractional digits). "s" denotes scale or the number of fractional digits. For example, if a column is defined as DECIMAL(5, 4), the numbers 3.14, 3.1415, 3.141592 are stored in the column as 3.1400, 3.1415, 3.1415, respectively keeping the specified precision(5) and scale(4).The precision p, can range from 1 to 34. The scale can range from 0 to p. If the scale is not specified, it defaults to 0.When precision and scale are not specified, DECIMAL becomes a floating-point decimal number. In this case, precision and scale can vary within the range 1 to 34 for precision and -6,111 to 6,176 for scale depending on the stored value.Examples: 0.0000001234 (1234 x 10-10) has the precision 4 and the scale 10. 1.0000001234 (10000001234 x 10-10) has the precision 11 and scale 10. 1234000000 (1234x106) has the precision 4 and scale -6.When precision and scale are not specified, DECIMAL becomes a floating-point decimal number. In this case, precision and scale can vary within the range described above, 1~34 for precision and -6,111~6,176 for scale depending on the stored value.

SMALLDECIMALThe SMALLDECIMAL is a floating-point decimal number. The precision and scale can vary within the range, 1~16 for precision and -369~368 for scale depending on the stored value. SMALLDECIMAL is supported only on column store.DECIMAL and SMALLDECIMAL are floating-point types. For instance, a decimal column can store any of 3.14, 3.1415, 3.141592 whilst maintaining their precision.



DECIMAL(p, s) is the SQL standard notation for fixed-point decimal. For instance, 3.14, 3.1415, 3.141592 are stored in a decimal(5, 4) column as 3.1400, 3.1415, 3.1415, respectively keeping the specified precision(5) and scale(4).

REALThe REAL data type specifies a single-precision 32-bit floating-point number.

DOUBLEThe DOUBLE data type specifies a single-precision 64-bit floating-point number. The minimum value is -1.79769 x 10308 and the maximum value is 1.79769x10308 . The smallest positive DOUBLE value is 2.2207x10-308 and the largest negative DOUBLE value is -2.2207x10-308.

FLOAT(n)The FLOAT(n) data type specifies a 32-bit or 64-bit real number, where n specifies the number of significant bits and can range between 1 and 53.When you use the FLOAT(n) data type, if n is smaller than 25, it becomes a 32-bit REAL data type. If n is greater than or equal to 25, it then becomes a 64-bit DOUBLE data type. If n is not declared, it becomes a 64-bit double data type by default.

Character String Types

The character string data types are used to store values that contain character strings. While VARCHAR data types contain ASCII character strings, NVARCHAR are used for storing Unicode character strings. VARCHAR

The VARCHAR(n) data type specifies a variable-length ASCII character string, where n indicates the maximum length and is an integer between 1 and 5000.

NVARCHARThe NVARCHAR(n) data type specifies a variable-length Unicode character set string, where n indicates the maximum length and is an integer between 1 and 5000.

ALPHANUMThe ALPHANUM(n) data type specifies a variable-length character string which contains alpha-numeric characters, where n indicates the maximum length and is an integer between 1 and 127.

SHORTTEXTThe SHORTTEXT(n) data type specifies veriable-length character string which supports textsearch-features and stringsearch-features. This is not a standalone sql-type. Selecting a SHORTTEXT(n)-column yields a column of type NVARCHAR(n).

::= SHORTTEXT ( )

::= [{, }...]

::= | SYNC[HRONOUS]

Binary Types

Binary types are used to store bytes of binary data. VARBINARY



The VARBINARY(n) data type is used to store binary data of a specified maximum length in bytes, where n indicates the maximum length and is an integer between 1 and 5000.

Large Object (LOB) Types

LOB (large objects) data types, CLOB, NCLOB and BLOB, are used to store a large amount of data such as text documents and images. The maximum size of an LOB is 2 GB. BLOB

The BLOB data type is used to store large binary data. CLOB

The CLOB data type is used to store large ASCII character data. NCLOB

The NCLOB data type is used to store a large Unicode character object. TEXT

The TEXT data type specifies which supports textsearch-features. This is not a standalone sql-type. Selecting a TEXT-column yields a column of type NCLOB.

::= TEXT

::= [{, }...]

::= | [SYNC[HRONOUS] | [ASYNC[HRONOUS] FLUSH [QUEUE] | EVERY MINUTES [[OR] AFTER DOCUMENTS] ]

Syntax-rules common to TEXT and SHORTTEXT

::= LANGUAGE COLUMN | LANGUAGE DETECTION '(' ')' | MIME TYPE COLUMN | FUZZY SEARCH INDEX [ON|OFF] | PHRASE INDEX RATIO [ON|OFF] | CONFIGURATION | SEARCH ONLY [ON|OFF] | FAST PREPROCESS [ON|OFF]

LOB types are provided for storing and retrieving such large data. LOB types support the following operations. The length() function returns the LOB length in bytes. LIKE can be used to search LOB columns.The LOB types have the following restrictions: LOB columns cannot appear in ORDER BY or GROUP BY clauses. LOB columns cannot appear in FROM clauses as a join predicate. LOB columns cannot appear in WHERE clauses as a predicate except LIKE, CONTAINS, =, or . LOB columns cannot appear in SELECT clauses as an aggregate function argument. LOB columns cannot appear in SELECT DISTINCT clauses. LOB columns cannot be used in set operations such as EXCEPT. UNION ALL is an exception. LOB columns cannot be used as a primary key.



LOB columns cannot be used in CREATE INDEX statements. LOB columns cannot be used in statistics update statements.

Data Type Conversion

This section describes the data type conversion allowed in SAP HANA Database. Explicit type conversion

The type of an expression result, for example a field reference, a function on fields, or literals can be converted using the following functions: CAST, TO_ALPHANUM, TO_BIGINT, TO_VARBINARY, TO_BLOB, TO_CLOB, TO_DATE, TO_DATS, TO_DECIMAL, TO_DOUBLE, TO_INTEGER, TO_INT, TO_NCLOB, TO_NVARCHAR, TO_REAL, TO_SECONDDATE, TO_SMALLINT, TO_TINYINT, TO_TIME, TO_TIMESTAMP, TO_VARCHAR.

Implicit type conversionWhen a given set of operand/argument types does not match what an operator/function expects, a type conversion is carried out by the SAP HANA Database. This conversion only occurs if a relevant conversion is available and if it makes the operation/function executable. For instance, a comparison of BIGINT and VARCHAR is performed by implicitly converting VARCHAR to BIGINT. The entire explicit conversions can be used for implicit conversion except for the TIME and TIMESTAMP data types. TIME and TIMESTAMP can be converted to each other using TO_TIME(TIMESTAMP) and TO_TIMESTAMP(TIME).

Examples Table 7: Table 8: Implicit Type conversion ExamplesInput Expression Transformed Expression with Implicit Conversion

BIGINT > VARCHAR BIGINT > BIGINT(VARCHAR)

BIGINT > DECIMAL DECIMAL(BIGINT) > DECIMAL

TIMESTAMP > DATE TIMESTAMP > TIMESTAMP(DATE)

DATE > TIME Error because there is no conversion available between DATE and TIME

In the tables below, Boxes with "OK" means data type conversions are allowed without any checks. Boxes with "CHK" means the data type can be converted if the data is valid for the target type. Boxes with "-" indicates that data type conversion is not allowed.The rules shown are applicable to both implicit and explicit conversion except for Time to Timestamp conversion. Only explicit conversions are allowed for converting the Time data type to Timestamp using the TO_TIMESTAMP or CAST functions.

Typed ConstantA constant is a symbol that represents a specific fixed data value. Character string contant

A character string constant is enclosed in single quotation marks. 'Brian' '100'Unicode string has a similar format to character string but is preceded by an N identifier (N stands for National Language in the SQL-92 standard). The N prefix must be uppercase.



N'abc' SELECT 'Brian' "character string 1", '100' "character string 2", N'abc' "unicode string" FROM DUMMY;

character string 1, character string 2, unicode string Brian, 100, abc

Number constantA number constant is represented by a string of numbers that are not enclosed in quotation marks. Numbers may contain a decimal point or scientific notation. 123 123.4 1.234e2A hexadecimal number constant is a string of hexadecimal numbers and has the prefix 0x. 0x0abc

SELECT 123 "integer", 123.4 "decimal1", 1.234e2 "decimal2", 0x0abc "hexadecimal" FROM DUMMY;

integer, decimal1, decimal2, hexadecimal 123, 123.4, 123.4, 2748

Binary string constantA binary string has the prefix X and is a string of hexadecimal numbers that are enclosed in quotation marks. X'00abcd' x'dcba00'

SELECT X'00abcd' "binary string 1", x'dcba00' "binary string 2" FROM DUMMY;

binary string 1, binary string 2 00ABCD, DCBA00

Date/Time/Timestamp constantDate, Time and Timestamp each have the following prefixes. date'2010-01-01' time'11:00:00.001' timestamp'2011-12-31 23:59:59'

SELECT date'2010-01-01' "date", time'11:00:00.001' "time", timestamp'2011-12-31 23:59:59' "timestamp" FROM DUMMY;

date, time, timestamp 2010-01-01, 11:00:00, 2011-12-31 23:59:59.0

1.4 Predicates

A predicate is specified by combining one or more expressions, or logical operators, and returns one of the following logical/truth values: TRUE, FALSE, or UNKNOWN.



Comparison Predicates Range Predicate In Predicate Exists Predicate LIKE Predicate NULL Predicate CONTAINS Predicate

1.4.1 Comparison Predicates

Syntax

::= { = | != | | > | < | >= |

1.4.2 Range Predicate

Syntax

::= [NOT] BETWEEN AND

Syntax Elements

::= ::= ::=

Expressions are either simple expression such as a character, a date or a number, or expression can also be a scalar subquery (see Expressions and Subquery).

NOT

Inverts the operation of the BETWEEN predicate. Specifies that a true will be returned when is not in the range of values specified between and .

Description

Compares a value with a list of values within the provided range.

The range predicate returns true if is within the range specified by and .

NoteA true will only be returned if has a value less than or equal to .



1.4.3 In Predicate

Syntax

::= [NOT] IN { | }

Syntax Elements

::= ::= [{, }...]


NOT

Inverts the operation of the IN predicate. Specifies that a true will be returned when is not in the set of values specified by or the .

Description

A value is compared with a specified set of values. A true will be returned if the value of is found in the or .

1.4.4 Exists Predicate

Syntax

::= [NOT] EXISTS ( )



Syntax Elements

NOT

Inverts the operation of the EXISTS predicate. Specifies that a true will be returned when the returns an empty result set and false when the returns a result set.

For information on subqueries, see Subquery

Description

Returns true if the returns a result set that is not empty and returns false if the returns an empty result set.

1.4.5 LIKE Predicate

Syntax

::= [NOT] LIKE [ESCAPE ]

Syntax Elements

::= ::= ::=


NOT

Inverts the operation of the LIKE predicate.

ESCAPE

Specifies an escape character to be used in the comparison string . The escape character allows the underscore (_) or percentage sign (%) to be matched.



Description

The LIKE predicate performs string comparisons. is tested for a pattern contained in . Wildcard characters ( % ) and ( _ ) can be used in the comparison string . LIKE returns true if the pattern specified by expression2 is found.

The percentage sign (%) matches zero or more characters and underscore (_) matches exactly one character. To match a percent sign or underscore with the LIKE predicate, an escape character must be used.

Using ESCAPE , you can specify the escape character that will be used allowing the underscore (_) or percentage sign (%) to be matched.

1.4.6 NULL Predicate

Syntax

::= IS [NOT] NULL

Syntax Elements


IS NULL

Returns true if the value of is NULL.

IS NOT NULL

Returns true if the value of is not NULL.

Description

Performs a comparison of the value of an expression with NULL.



1.4.7 CONTAINS Predicate

The CONTAINS predicate is used to search for text-matches to a search string in subqueries.Syntax:

::= CONTAINS '(' ',' ')' | CONTAINS '(' ',' ',' ')' ::= '*' | | '(' ')' ::= ::= | ::= empty | ::= | | ::= | ',' := | ::= EXACT ::= FUZZY | FUZZY '(' ')' | FUZZY '(' ',' ')' ::= LINGUISTIC ::= WEIGHT '(' ')' :: LANGUAGE '(' ')' ::=

search_stringThe freestyle-search-string format is used (eg. Peter "Palo Alto" OR Berlin -"SAP LABS" )

search_specifierIf the search_specifier clause is not specified EXACT is taken as default

EXACTEXACT returns true for those records where exact matches of the searchterms are found in the search-attributes

FUZZYFUZZY returns true for those records where words similar to the searchterms are found in the search-attributes (e.g. spelling errors will be ignored to a certain extent)

float_const



If float_const is omitted, then 0.8 is the default. This default can be overridden by defining parameter FUZZINESSTHRESHOLD supported by columnstore join-views

WEIGHTIf a weights list is specified, it must be the same size as the number of (expanded) columns in

LANGUAGELANGUAGE is used during preprocessing of the search string and as a pre-search filter. Only documents which match the search string and the language specified are returned.

LINGUISTICLINGUISTIC returns true for those records where word-variants of the searchterms are found in the search-attributes (e.g. searching for 'cats' will also return records which contain 'cat')

Limitations: If there are multiple CONTAINS predicates specified in the where clause of a select statement, then only one of the predicates may consist of more than one column in the list

The CONTAINS-predicate works only on column store tables (simple tables and join-views)

Examples:Exact search

select * from T where contains(column1, 'dog OR cat') -- EXACT is implicit select * from T where contains(column1, 'dog OR cat', EXACT) select * from T where contains(column1, '"cats and dogs"') -- phrase search

Fuzzy search

select * from T where contains(column1, 'catz', FUZZY(0.8))

Linguistic search:

select * from T where contains(column1, 'catz', LINGUISTIC)

Freestyle search:The freestyle-search is a search mulitple columns.

select * from T where CONTAINS( (column1,column2,column3), 'cats OR dogz', FUZZY(0.7)) select * from T where CONTAINS( (column1,column2,column3), 'cats OR dogz', FUZZY(0.7))



1.5 Operators

Unary and Binary Operators Operator Precedence Arithmetic Operators String Operators Comparsion Operators Logical Operators Set OperatorsYou can perform arithmetic operations in expressions by using operators. Operators can be used for calculation, value comparison or to assign values.

Unary and Binary Operators

Table 11: Table 10. Unary and binary operatorsOperator Operation Format Description

Unary A unary operator applies to one operand or a single value expression.

operator operand unary plus operator(+)

unary negation operator(-)

logical negation(NOT)

Binary Binary A binary operator applies to two operands or two value expressions.

operand1 operator operand2

multiplicative operators ( *, / )

additive operators ( +,- )

comparison operators( =,!=,,=)

logical operators ( AND, OR )

Operator Precedence

An expression can use several operators. If the number of operators is greater than one then the SAP HANA Database will evaluate them in order of operator precedence. You can change the order of evaluation by using parentheses, as expressions contained within parentheses are always evaluated first.



If parentheses are not used, the operators have the precedence indicated by the table below. Please note, the SAP HANA Database will evaluate operators with equal precedence from left to right within an expression.

Table 12: Table 11. SQL operator precedencePrecedence Operator Operation

Highest () parentheses

+, - unary positive and negative operation

*, / multiplication, division

+, - addition, subtraction

|| concatenation

=, !=, , =, IS NULL, LIKE, BETWEEN

comparsion

NOT logical negation

AND conjunction

Lowest OR disjunction

Arithmetic Operators

You use arithmetic operators to perform mathematical operations such as adding, subtracting, multiplying, dividing and negation of numeric values.

Table 13: Table 12. Arithmetic operatorsOperator Description

- Negation. If the expression is the NULL value, the result is NULL.

+ Addition. If either expression is the NULL value, the result is NULL.

- Subtraction. If either expression is the NULL value, the result is NULL.

* Multiplication. If either expression is NULL, the result is NULL.

/ Division. If either expression is NULL, or if the second expression is 0, an error is returned.



String Operators

A concatenation operator combines two items such as strings, expressions or constants into one.

Table 14: Table 13. Concatenation operatorsOperator Description

|| String concatenation (two vertical bars).If either string is NULL, it returns NULL.

For VARCHAR or NVARCHAR type strings, leading or trailing spaces are kept. If either string is of data type NVARCHAR, the result has data type NVARCHAR and is limited to 5000 characters. The maximum length for VARCHAR concatenation is also limited to 5000 characters.

Comparsion Operators

Syntax:

::=

Table 15: Table 14. Comparison operatorsOperator Description Example

= Equal to SELECT * FROM students WHERE id = 25;

> Greater than SELECT * FROM students WHERE id > 25;

< Less than SELECT * FROM students WHERE id < 25;

>= Greater than or equal to SELECT * FROM students WHERE id >= 25;

Logical Operators

Search conditions can be combined using AND or OR operators. You can also negate them using the NOT operator.

Table 16: Table 15. Logical operatorsOperator Syntax Description

AND WHERE condition1 AND condition2 When using AND, the combined condition is TRUE if both conditions are TRUE, FALSE if either condition is FALSE, and UNKNOWN otherwise.

OR WHERE condition1 OR condition2 When using OR, the combined condition is TRUE if either condition is TRUE, FALSE if both conditions are FALSE, and UNKNOWN otherwise.

NOT WHERE NOT condition The NOT operator is placed before a condition to negate the condition. The NOT condition is TRUE if condition is FALSE, FALSE if condition is TRUE, and UNKNOWN if condition is UNKNOWN.

Set Operators

The operators described in this section perform set operations on the results of two or more queries.

Table 17: Table 16. Set operatorsOperator Returned Value

UNION Combines the results of two or more select statements or query expressions

UNION ALL Combines the results of two or more select statements or query expressions, including all duplicate rows.

INTERSECT Combines the results of two or more select statements or query expressions, and returns all common rows.

EXCEPT Takes output from the first query and then removes rows selected by the second query.



1.6 Expressions

Case Expressions Function Expressions Aggregate Expressions Subqueries in ExpressionsAn expression is a clause that can be evaluated to return values.

Syntax

::= | | | ( ) | ( ) | - | | | | [.]

Case Expressions

A case expression allows the user to use IF - THEN - ELSE logic without using procedures in SQL statements.Syntax

::= |

::= CASE WHEN THEN [{ WHEN THEN }] [ ELSE ] END

> ::= CASE WHEN THEN [{ WHEN THEN }] [ ELSE ] END

::= OR | AND | NOT | ( ) |

For more information on predicates, see Predicates.



If the expression following the CASE statement is equal to the expression following the WHEN statement, then the expression following the THEN statement is returned. Otherwise the expression following the ELSE statement is returned if it exists.

Function Expressions

SQL built-in functions can be used as an expression.Syntax

::= ( [{, }...] )

Aggregate Expressions

An aggregate expression uses an aggregate function to calculate a single value from the values of multiple rows in a column.Syntax

::= COUNT(*) | ( [ ALL | DISTINCT ] ) ::= COUNT | MIN | MAX | SUM | AVG | STDDEV | VAR

Aggregate name Description

COUNT Counts the number of rows returned by a query. COUNT(*) returns the number of rows, regardless of the value of those rows and including duplicate values. COUNT() returns the number of non-NULL values for that expression returned by the query.

MIN Returns the minimum value of expression.

MAX Returns the maximum value of expression.

SUM Returns the sum of expression.

AVG Returns the arithmetical mean of expression.

STDDEV Returns the standard deviation of given expression as the square root of VARIANCE function.

VAR Returns the variance of expression as the square of standard deviation.



Subqueries in Expressions

A subquery is a SELECT statement enclosed in parentheses. The SELECT statement can contain one and only one select list item. When used as an expression a scalar subquery is allowed to return only zero or one value.Syntax

::= ()

Within the SELECT list of the top level SELECT, or in the SET clause of an UPDATE statement, you can use a scalar subquery anywhere that you can use a column name. However, scalar_subquery cannot be used inside GROUP BY clause.Example:For example, the following statement returns the number of employees in each department, grouped by department name:

SELECT DepartmentName, COUNT(*), 'out of', (SELECT COUNT(*) FROM Employees) FROM Departments AS D, Employees AS E WHERE D.DepartmentID = E.DepartmentID GROUP BY DepartmentName;
