mysql_error

PHP function Edit on GitHub ✎

(PHP 4, PHP 5)

Returns the text of the error message from previous MySQL operation

Note mysqli_errorPDO::errorInfo

Description

mysql_error(resource $link_identifier = NULL): string

Returns the error text from the last MySQL function. Errors coming back from the MySQL database backend no longer issue warnings. Instead, use mysql_error() to retrieve the error text. Note that this function only returns the error text from the most recently executed MySQL function (not including mysql_error() and mysql_errno()), so if you want to use it, make sure you check the value before calling another MySQL function.

Parameters

Return Values

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

Examples

mysql_error() example

php
<?php
$link = mysql_connect("localhost", "mysql_user", "mysql_password");

mysql_select_db("nonexistentdb", $link);
echo mysql_errno($link) . ": " . mysql_error($link). "\n";

mysql_select_db("kossu", $link);
mysql_query("SELECT * FROM nonexistenttable", $link);
echo mysql_errno($link) . ": " . mysql_error($link) . "\n";
?>

The above example will output something similar to:

output
1049: Unknown database 'nonexistentdb'
1146: Table 'kossu.nonexistenttable' doesn't exist
