mysql_error

Returns the text of the error message from previous MySQL operation (PHP 4, PHP 5, PECL mysql:1.0)
string mysql_error ( [resource link_identifier] )

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

link_identifier: The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level warning is generated.

Return Values

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

mysql_query("SELECT * FROM nonexistenttable", $link);

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