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
Description
string db2_conn_error
([ resource $connection
] )
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
-
connection
-
A 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().
<?php
$conn = db2_connect('badname', 'baduser', 'badpassword');
if (!$conn) {
print "SQLSTATE value: " . db2_conn_error();
}
?>
The above example will output:
db2_commit
