ingres_errno

Returns an integer containing the last error number. If no error was reported 0 is returned.

If a link resource is passed to ingres_errno() it returns the last error recorded for the link. If no link is passed, then ingres_errno() returns the last error reported using the default link.

The function, ingres_errno(), should always be called after executing a database query. Calling another function before ingres_errno() is called will reset or change any error code from the last Ingres function call.

The connection link identifier

Returns an integer containing the last error number. If no error was reported, 0 is returned.

<?php
$link = ingres_connect($database, $user, $password);

$result = ingres_query($link, "select * from table");

$error_code = ingres_errno($link);

if ( $error_code != 0 ) {
   echo "An error occurred - " . $error_code;
}
?>
