# ingres_errno

(PECL)

ingres_errno -- Gets the last ingres error number generated

## Description

int ingres_errno ( [resource link] )

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.

Example 1. ingres_errno() example
`<?php $link = ingres_connect($database, $user, $password); ingres_query("select * from table", $link); $error_code = ingres_errno($link); if ( $error_code != 0 ) { echo "An error occured - " . $error_code; } ?>`
