Embedded SQL

From Wikipedia, the free encyclopedia

Jump to:navigation,search

Embedded SQL is a method of combining thecomputingpower of aprogramming languageand thedatabasemanipulationcapabilities ofSQL. Embedded SQLstatementsare SQLstatements written inline with the programsource codeof the host language. The embedded SQL

statements areparsedby an embedded SQLpreprocessorand replaced by host-languagecallsto

a codelibrary. The output from the preprocessor is then compiled by the hostcompiler. Thisallows programmers to embed SQL statements in programs written in any number of languages

such as:C/C++,COBOLandFortran.

TheANSISQL standards committee defined the embedded SQL standard in two steps: a

formalism called Module Language was defined, then the embedded SQL standard was derived

from Module Language.

[1]

The SQL standard defines embedding of SQL as embedded SQL andthe language in which SQL queries are embedded is referred to as the host language. A popular

host language is C. The mixed C and embedded SQL is calledPro*CinOracleandSybase

database management systems. In thePostgreSQLdatabase management system this

precompiler is calledECPG. Other embedded SQL precompilers are Pro*Ada, Pro*COBOL,Pro*FORTRAN, Pro*Pascal, and Pro*PL/I.

2/3

IBM DB2version 9 for Linux, UNIX and Windows supports embedded SQL for C, C++, Java,

COBOL, FORTRAN and REXX although support for FORTRAN and REXX has beendeprecated.[2]

Oracle Corporation

Ada

Pro*Ada was officially desupported byOraclein version 7.3. Starting with Oracle8,Pro*Ada has been replaced by SQL*Module but appears to have not been updated

since.[3]SQL*Module is a module language that offers a different programming method

from embedded SQL. SQL*Module supports the Ada83 language standard for Ada.

C/C++Pro*Cbecame Pro*C/C++ with Oracle8. Pro*C/C++ is currently supported as of Oracle

Database 11g.

COBOL

Pro*COBOL is currently supported as of Oracle Database 11g.

FortranPro*FORTRAN is no longer updated as of Oracle8 but Oracle will continue to issue

patch releases as bugs are reported and corrected.[4]

Pascal

Pro*Pascal was not released with Oracle8.[4]

PL/IPro*PL/I was not released with Oracle8. The Pro*PL/I Supplement to the Oracle

Precompilers Guide, however, continues to make appearances in the OracleDocumentation Library (current as of release 11g).
