Updating existing rows in a table requires to run the UPDATE statement with a WHERE clause to identify the row. The following sample script updates one row with two new values:
<?php include "mysql_connection.php"; $sql = "UPDATE fyi_links SET notes='Nice site.', counts=8" . " WHERE id = 102"; if (mysql_query($sql, $con)) { print(mysql_affected_rows() . " rows updated.\n"); } else { print("SQL statement failed.\n"); } mysql_close($con); ?>
If you run this script, you will get something like this:
1 rows updated.
