db2_conn_error Returns a string containing the SQLSTATE returned by the last connection attempt &reftitle.description; stringdb2_conn_error resourceconnection db2_conn_error returns an SQLSTATE value representing the reason the last attempt to connect to a database failed. As db2_connect returns &false; in the event of a failed connection attempt, you do not pass any parameters to db2_conn_error to retrieve the SQLSTATE value. If, however, the connection was successful but becomes invalid over time, you can pass the connection parameter to retrieve the SQLSTATE value for a specific connection. To learn what the SQLSTATE value means, you can issue the following command at a DB2 Command Line Processor prompt: db2 '? sqlstate-value'. You can also call db2_conn_errormsg to retrieve an explicit error message and the associated SQLCODE value. &reftitle.parameters; connection A connection resource associated with a connection that initially succeeded, but which over time became invalid. &reftitle.returnvalues; Returns the SQLSTATE value resulting from a failed connection attempt. Returns an empty string if there is no error associated with the last connection attempt. &reftitle.examples; The following example demonstrates how to return an SQLSTATE value after deliberately passing invalid parameters to db2_connect. ]]> &example.outputs; &reftitle.seealso; db2_conn_errormsg db2_connect db2_stmt_error db2_stmt_errormsg
