Delete Data In a Database

The DELETE FROM statement is used to delete records from a database table.

Syntax

DELETE FROM table_name WHERE column_name = some_value

Note: SQL statements are not case sensitive. DELETE FROM is the same as delete from.

To get PHP to execute the statement above we must use the mysql_query() function. This function is used to send a query or command to a MySQL connection.

Example

Earlier in the tutorial we created a table named "Person". Here is how it looks:

FirstName	LastName	Age
Peter	Griffin	35
Glenn	Quagmire	33

The following example deletes all the records in the "Person" table where LastName='Griffin':

<?php $con = mysql_connect("localhost","peter","abc123"); if (!$con)   {   die('Could not connect: ' . mysql_error());   } mysql_select_db("my_db", $con);   mysql_query("DELETE FROM Person WHERE LastName='Griffin'"); mysql_close($con); ?>

After the deletion, the table will look like this:

FirstName	LastName	Age
Glenn	Quagmire	33
