After each embedded SQL statement is executed, error and status information is returned in the SQL Communications Area (SQLCA).
Oracle, Sybase and Informix all have different versions of the SQLCA. The Oracle, Sybase and Informix SQLCA's all have a SQLCODE, SQLERRML, SQLERRMC and a SQLWARN. The sizes and the positions of these fields can differ between the precompilers.
For details of the layout of the SQLCA data structure, see the topic The SQLCA Data Structure.
OpenESQL
The SQLCA provided with Studio Enterprise Edition for use with OpenESQL contains two variables (SQLCODE and SQLSTATE) plus a number of warning flags which are used to indicate whether an error has occurred in the most recently executed SQL statement.
COBSQL
See your third-party vendor documentation for details on testing the success or failure of a given SQL statement.
