The DELETE FROM statement is used to delete records from a database table. [color=FA0309]Syntax[/color]
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.
[color=FA0309]Example[/color]WHERE column_name = some_value
Earlier in the tutorial we created a table named "Person". Here is how it looks:
<?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:$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
} mysql_select_db("my_db", $con); mysql_query("DELETE FROM Person WHERE LastName='Griffin'"); mysql_close($con);
?>
