Objectives• Change the font or font size for SQL queries• Include fields and criteria in SQL queries• Use computed fields and built-in functions in SQL

queries• Sort the results in SQL queries• Use multiple functions in the same command


Objectives• Group the results in SQL queries• Join tables in SQL queries• Use subqueries• Compare SQL queries with Access-generated SQL• Use INSERT, UPDATE, and DELETE queries to

update a database


Plan Ahead• Select the fields for the query• Determine which table or tables contain these

fields• Determine criteria• Determine sort order• Determine grouping• Determine any update operations to be

performed


Starting Access• Click the Start button on the Windows Vista taskbar to

display the Start menu• Click All Programs at the bottom of the left pane on the

Start menu to display the All Programs list and then click Microsoft Office in the All Programs list to display the Microsoft Office list.

Changing the Font Size


Creating a New SQL Query• Hide the Navigation Pane• Click Create on the Ribbon to display the Create tab• Click the Query Design button on the Create tab to

create a query• Close the Show Table dialog box without adding

any tables• Click the View button arrow to display the View

menu• Click SQL View to view the query in SQL view


Creating a New SQL Query


Including Only Certain Fields• Type SELECT [Client Number],[Client Name],[Amount Paid],[Current Due] as the first line of the command, and then press the ENTER key

• Type FROM [Client] as the second line, press the ENTER key and then type a semicolon (;) on the third line

• Click the View button to view the results


Including Only Certain Fields


Preparing to Enter a New SQL Query• Click the View button arrow to display the View

button menu• Click SQL View to return to SQL view


Including All Fields• Delete the current command, type SELECT *

as the first line of the command, and then press the ENTER key

• Type FROM [Client] as the second line, press the ENTER key, and type a semicolon on the third line

• Click the View button to view the results


Including All Fields


Using Criterion Involving a Numeric Field

• Click the View button arrow, click SQL View to return to SQL view, and then delete the current command

• Type SELECT [Client Number],[Client Name] as the first line of the command

• Type FROM [Client] as the second line• Type WHERE [Current Due]=0 as the third

line and then type a semicolon on the fourth line• Click the View button to view the results


Using Criterion Involving a Numeric Field


Using a Criterion Involving a Text Field

• Return to SQL view, delete the previous query, and type SELECT [Client Number],[Client Name] as the first line of the command

• Type FROM [Client] as the second line• Type WHERE [City]='Berls' as the third

line and type a semicolon on the fourth line• Click the View button to view the results


Using a Criterion Involving a Text Field


Using a Compound Criterion• Return to SQL view, delete the previous query, and

type SELECT [Client Number],[Client Name] as the first line of the command

• Type FROM [Client] as the second line• Type WHERE [City]='Tarleton’ as the

third line• Type AND [Current Due]=0 as the fourth

line and type a semicolon on the fifth line• Click the View button to view the results


Using a Compound Criterion


Using NOT in a Criterion• Return to SQL view and delete the previous query• Type SELECT [Client Number],[Client Name] as the first line of the command

• Type FROM [Client] as the second line• Type WHERE NOT [City]= 'Tarleton' as

the third line and type a semicolon on the fourth line

• View the results


Using NOT in a Criterion


Using a Computed Field• Return to SQL view and delete the previous query• Type SELECT [Client Number], [Client Name],[Amount Paid] +[Current Due] AS [Total Amount] as the first line of the command

• Type FROM [Client] as the second line• Type WHERE [Current Due]>0 as the third

line and type a semicolon on the fourth line• View the results


Using a Computed Field


Sorting the Results• Return to SQL view and delete the previous query• Type SELECT [Client Number], [Client Name],[Amount Paid],[Current Due], [Recruiter Number] as the first line of the command

• Type FROM [Client] as the second line• Type ORDER BY [Recruiter Number],[Amount Paid] as the third line and type a semicolon on the fourth line



Sorting the Results


Using a Built-In Function• Return to SQL view and delete the previous

query• Type SELECT COUNT(*) as the first line of

the command• Type FROM [Client] as the second line• Type WHERE [Recruiter Number]='21'

as the third line and type a semicolon on the fourth line



Using a Built-In Function


Using Multiple Functions in the Same Command

• Return to SQL view and delete the previous query

• Type SELECT COUNT(*), SUM([Amount Paid]) as the first line of the command

• Type FROM [Client] as the second line and type a semicolon on the third line



Using Multiple Functions in the Same Command


Using Grouping• Return to SQL view and delete the previous query• Type SELECT [Recruiter Number],SUM([Amount Paid]) AS [Total Paid],SUM([Current Due]) AS [Total Due] as the first line of the command

• Type FROM [Client] as the second line• Type GROUP BY [Recruiter Number] as the third

line• Type ORDER BY [Recruiter Number] as the fourth

line and type a semicolon on the fifth line• View the results


Using Grouping


Restricting the Groups that Appear• Return to SQL view and delete the previous

query• Click the beginning of the fourth line (ORDER BY

[Recruiter Number]) and press the ENTER key to insert a new blank line

• Click the beginning of the new blank line, and then type HAVING SUM([Current Due])>40000 as the new fourth line



Restricting the Groups that Appear


Joining Tables• Return to SQL view and delete the previous query• Type SELECT [Client Number], [Client Name],[Client]. [Recruiter Number],[First Name],[Last Name] as the first line of the command

• Type FROM [Client], [Recruiter] as the second line

Joining Tables


Restricting the Records in a Join• Return to SQL view and delete the previous

query• Click immediately prior to the semicolon on the

last line• Type AND [Current Due] > 0 and press

the ENTER key• View the results


Restricting the Records in a Join


Joining a Table to Itself• Return to SQL view and delete the previous query.• Type SELECT F.[Client Number],F.[Client Name], S.[Client Number],S.[Client Name],F.[City] as the first line of the command

• Type FROM [Client] F, [Client] S as the second line

• Type WHERE F.[City]=S.[City] as the third line• Type AND F.[Client Number]<S. [Client Number] as the fourth line and type a semicolon on the fifth line



Joining a Table to Itself


Using a Subquery• Return to SQL view and delete the previous

query• Type SELECT [Recruiter Number],[First Name],[Last Name] as the first line of the command

• Type FROM [Recruiter] as the second line• Type WHERE [Recruiter Number] IN as

the third line


Using a Subquery• Type (SELECT [Recruiter Number] as

the fourth line• Type FROM [Client] as the fifth line• Type WHERE [City]='Berls') as the sixth

line and type a semicolon on the seventh line• View the results


Using a Subquery


Using an INSERT Command• If necessary, return to SQL view and delete the

existing query• Type INSERT INTO [Seminar Offerings] as the first line of the command

• Type VALUES as the second line• Type ('PR11','S01',8,0) as the third line

and type a semicolon on the fourth line


Using an INSERT Command• Run the query by clicking the Run button• When Access displays a message indicating the

number of records to be inserted, click the Yes button to insert the records


Using an INSERT Command


Using an UPDATE Command• Delete the existing query• Type UPDATE [Seminar Offerings] as the

first line of the command• Type SET [Hours Spent]=2 as the second line• Type WHERE [Client Number]= 'PR11' as

the third line• Type AND [Seminar Number]= 'S01' as the

fourth line and type a semicolon on the fifth line


Using an UPDATE Command


Using a DELETE Command• Delete the existing query• Type DELETE FROM [Seminar Offerings] as the

first line of the command• Type WHERE [Client Number]= 'PR11' as the

second line• Type AND [Seminar Number]= 'S01' as the third

line and type a semicolon on the fourth line• Run the query by clicking the Run button• When Access displays a message indicating the number of

records to be deleted, click the Yes button to delete the records


Using a DELETE Command


Closing a Query and Restoring the Font Size

• Click the Close ‘Query1’ button and then click the No button when asked if you want to save the changes
