# fbsql_errno

(PHP 4 >= 4.0.6)

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>";
    ?>
