db2_conn_error(PECL ibm_db2:1.0-1.6.2) db2_conn_error — Returns a string containing the SQLSTATE returned by the last connection attempt 说明
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:
参数
