fbsql_error

Returns the text of the error message from previous FrontBase operation (PHP 4 >= 4.0.6, PHP 5)
string fbsql_error ( [resource link_identifier ] )

说明

Returns the error text from the last fbsql function, or '' (the empty string) if no error occurred.

Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_error() to retrieve the error text. Note that this function only returns the error text 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 />";
?>
