Appendix C. SQLCA (SQL communication area)

 

An SQLCA is a set of variables that may be updated at the end of the execution of every SQL statement. A program that contains executable SQL statements may provide one, but no more than one SQLCA (unless a stand-alone SQLCODE or a stand-alone SQLSTATE variable is used instead), except in Java™, where the SQLCA is not applicable.

Instead of using an SQLCA, the GET DIAGNOSTICS statement can be used in all languages to return return codes and other information about the previous SQL statement. For more information, see GET DIAGNOSTICS.

The SQL INCLUDE statement can be used to provide the declaration of the SQLCA in all host languages except Java, RPG, or REXX. For information on the use of the SQLCA in a REXX procedure, see the Embedded SQL Programming book. For information on how to access the information regarding errors and warnings in Java, refer to the IBM® Developer Kit for Java.

In C, COBOL, FORTRAN, and PL/I, the name of the storage area must be SQLCA. Every SQL statement must be within the scope of its declaration.

If a stand-alone SQLCODE or SQLSTATE is specified in the program, the SQLCA must not be included. For more information, see SQL return codes.
