# fbsql_errno

(PHP 4 >= 4.0.6, PHP 5)

fbsql_errno -- Returns the numerical value of the error message from previous FrontBase operation

## Description

int fbsql_errno ( [resource link_identifier] )

Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.

Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_errno() to retrieve the error code. Note that this function only returns the error code from the most recently executed fbsql function (not including fbsql_error() and fbsql_errno()), so if you want to use it, make sure you check the value before calling another fbsql function.

`<?php fbsql_connect("marliesle"); echo fbsql_errno() . ": " . fbsql_error() . "<br />"; fbsql_select_db("nonexistentdb"); echo fbsql_errno() . ": " . fbsql_error() . "<br />"; $conn = fbsql_query("SELECT * FROM nonexistenttable;"); echo fbsql_errno() . ": " . fbsql_error() . "<br />"; ?>`
