|
|
<p>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.</p>
|
||
|
|
<p>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 <a href="rbafzmstgetdiag.htm#getdiag">GET DIAGNOSTICS</a>.</p>
|
||
|
|
<p>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 <a href="../rzajp/rzajpkickoff.htm">Embedded
|
||
|
|
SQL Programming</a> book. For information on how to access the information
|
||
|
|
regarding errors and warnings in Java, refer to the <a href="../rzaha/whatitis.htm">IBM® Developer
|
||
|
|
Kit for Java</a>.</p>
|
||
|
|
<p>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.</p>
|
||
|
|
<p>If a stand-alone SQLCODE or SQLSTATE is specified in the program, the SQLCA
|
||
|
|
must not be included. For more information, see <a href="rbafzmstcksql.htm#cksql">SQL return codes</a>.</p>
