In this chapter, we'll learn to delete tables.
Table deletion is easy, but remember that all deleted tables are not recoverable. T he general syntax for table deletion is as follows -
DROP TABLE table_name ;
There are two options for performing table deletion: use command prompts or PHP scripts.
At the command prompt, simply use the DROP TABLE SQL command -
root@host# mysql -u root -p Enter password:******* mysql> use PRODUCTS; Database changed mysql> DROP TABLE products_tbl mysql> SELECT * from products_tbl ERROR 1146 (42S02): Table 'products_tbl' doesn't exist
PHP provides mysql_query() for deleting tables. S imply pass its second argument with the appropriate SQL command -
<html>
<head>
<title>Create a MariaDB Table</title>
</head>
<body>
<?php
$dbhost = 'localhost:3036';
$dbuser = 'root';
$dbpass = 'rootpassword';
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn ) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully<br />';
$sql = "DROP TABLE products_tbl";
mysql_select_db( 'PRODUCTS' );
$retval = mysql_query( $sql, $conn );
if(! $retval ) {
die('Could not delete table: ' . mysql_error());
}
echo "Table deleted successfully
";
mysql_close($conn);
?>
</body>
</html>
After successfully deleting the table, you will see the following output -
mysql> Table deleted successfully
