db2_conn_errormsg
Popis
string db2_conn_errormsg ( [resource connection] )db2_conn_errormsg() returns an error message and SQLCODE value representing the reason the last database connection attempt failed. As db2_connect() returns FALSE in the event of a failed connection attempt, do not pass any parameters to db2_conn_errormsg() to retrieve the associated error message and SQLCODE value.
If, however, the connection was successful but becomes invalid over time,
you can pass the connection
parameter to retrieve
the associated error message and SQLCODE value for a specific connection.
