db2_conn_errormsg — Returns the last connection error message and SQLCODE value

Description

db2_conn_errormsg ([ resource $connection ] ) : string

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.

Examples

Example #1 Retrieving the error message returned by a failed connection attempt

The following example demonstrates how to return an error message and SQLCODE value after deliberately passing invalid parameters to db2_connect().

<?php
$conn = db2_connect('badname', 'baduser', 'badpassword');
if (!$conn) {
    print db2_conn_errormsg();
}
?>

The above example will output:

[IBM][CLI Driver] SQL1013N  The database alias name
or database name "BADNAME" could not be found.  SQLSTATE=42705
 SQLCODE=-1013
