LEARN ABOUT PHP
mysql_errno
MYSQL_ERRNO(3) 1 MYSQL_ERRNO(3)
mysql_errno - Returns the numerical value of the error message from previous MySQL operation
SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
omysqli_errno(3)
o PDO::errorCode
int mysql_errno ([resource $link_identifier = NULL])
DESCRIPTION
Returns the error number from the last MySQL function.
Errors coming back from the MySQL database backend no longer issue warnings. Instead, use mysql_errno(3) to retrieve the error code. Note
that this function only returns the error code from the most recently executed MySQL function (not including mysql_error(3) and
mysql_errno(3)), so if you want to use it, make sure you check the value before calling another MySQL function.
o $
link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is
assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
is found or established, an E_WARNING level error is generated.
Returns the error number from the last MySQL function, or 0 (zero) if no error occurred.
Example #1
mysql_errno(3) example
<?php
$link = mysql_connect("localhost", "mysql_user", "mysql_password");
if (!mysql_select_db("nonexistentdb", $link)) {
echo mysql_errno($link) . ": " . mysql_error($link). "
";
}
mysql_select_db("kossu", $link);
if (!mysql_query("SELECT * FROM nonexistenttable", $link)) {
echo mysql_errno($link) . ": " . mysql_error($link) . "
";
}
?>
The above example will output something similar to:
1049: Unknown database 'nonexistentdb'
1146: Table 'kossu.nonexistenttable' doesn't exist
mysql_error(3), MySQL error codes.
