db2_conn_error - Returns a string containing the SQLSTATE returned by the last connection attempt
Code Examples

db2_conn_error( [resource$connection] ): string

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.



A connection resource associated with a connection that initially succeeded, but which over time became invalid.

Return Values

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.
