SQL communication area or simply SQLCA is a problem-diagnosis tool, it is a good idea to include instructions to display some of the information contained in the SQLCA in your application programs. An SQLCA in DB2 are collections of variables (i.e. SQLCA Copybook) that are updated after each SQL statement is executed. For example, the contents of SQLERRD(3), which indicates the number of rows that DB2 updates, inserts, or deletes, could be useful. If SQLWARN0 contains W, DB2 has set at least one of the SQL warning flags (SQLWARN1 through SQLWARNA). Let’s get started with What is SQLCA?
