(no version information, might be only in CVS)db2_conn_error -- Returns a string containing the SQLSTATE returned by the last connection attempt
Описание
string db2_conn_error ([resource connection])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.
