LEARN ABOUT PHP
mysql_affected_rows
MYSQL_AFFECTED_ROWS(3) 1 MYSQL_AFFECTED_ROWS(3)mysql_affected_rows - Get number of affected rows in previous MySQL operationSYNOPSIS
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_affected_rows(3)
o PDOStatement::rowCount
int mysql_affected_rows ([resource $link_identifier = NULL])
DESCRIPTION
Get the number of affected rows by the last INSERT, UPDATE, REPLACE or DELETE query associated with $link_identifier.
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 number of affected rows on success, and -1 if the last query failed.
If the last query was a DELETE query with no WHERE clause, all of the records will have been deleted from the table but this function will
return zero with MySQL versions prior to 4.1.2.
When using UPDATE, MySQL will not update columns where the new value is the same as the old value. This creates the possibility that
mysql_affected_rows(3) may not actually equal the number of rows matched, only the number of rows that were literally affected by the
query.
The REPLACE statement first deletes the record with the same primary key and then inserts the new record. This function returns the number
of deleted records plus the number of inserted records.
In the case of "INSERT ... ON DUPLICATE KEY UPDATE" queries, the return value will be 1 if an insert was performed, or 2 for an update of
an existing row.
Example #1
mysql_affected_rows(3) example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('mydb');
/* this should return the correct numbers of deleted records */
mysql_query('DELETE FROM mytable WHERE id < 10');
printf("Records deleted: %d
", mysql_affected_rows());
/* with a where clause that is never true, it should return 0 */
mysql_query('DELETE FROM mytable WHERE 0');
printf("Records deleted: %d
", mysql_affected_rows());
?>
The above example will output something similar to:
Records deleted: 10
Records deleted: 0
Example #2
mysql_affected_rows(3) example using transactions
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('mydb');
/* Update records */
mysql_query("UPDATE mytable SET used=1 WHERE id < 10");
printf ("Updated records: %d
", mysql_affected_rows());
mysql_query("COMMIT");
?>
The above example will output something similar to:
Updated Records: 10
Note
Transactions
If you are using transactions, you need to call mysql_affected_rows(3) after your INSERT, UPDATE, or DELETE query, not after the
COMMIT.
Note
SELECT Statements
To retrieve the number of rows returned by a SELECT, it is possible to use mysql_num_rows(3).
Note
Cascaded Foreign Keys
mysql_affected_rows(3) does not count rows affected implicitly through the use of ON DELETE CASCADE and/or ON UPDATE CASCADE in for-
eign key constraints.
mysql_num_rows(3), mysql_info(3).
