(PECL)
db2_conn_error -- Returns a string containing the SQLSTATE returned by the last connection attemptDescription
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.
Parameters
connectionA 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.
Examples
Example 1. Retrieving an SQLSTATE value for a failed connection attempt The following example demonstrates how to return an SQLSTATE value after deliberately passing invalid parameters to db2_connect().
The above example will output:
