MySQL Delete

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:

First Name	Last Name	Age
Bill	Gates	36
Nancy	Varghese	33

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

<?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 last_name='Gates'");
mysql_close($con);

?>

After the deletion, the table will look like this:
