Description
string
mysql_error ( [resource link_identifier])
Returns the error text from the last MySQL function, or
'' (the empty string) if no error occurred.
If no link is explicitly passed to the function, the last
successful open link will be used to retrieve the error message
from the MySQL server.
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.
Example 1. mysql_error() example |
<?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 would produce the following output:
1049: Unknown database 'nonexistentdb'
1146: Table 'kossu.nonexistenttable' doesn't exist |
