It is very easy to drop an existing MySQL table, but you need to be very careful while deleting any existing table because data lost will not be recovered after deleting a table.
Syntax:
Here is generic SQL syntax to drop a MySQL table:
DROP TABLE table_name ;
Dropping Tables from Command Prompt:
This needs just to execute DROP TABLE SQL command at mysql> prompt.
Example:
Here is an example, which deletes tutorials_tbl:
root@host# mysql -u root -p Enter password:******* mysql> use TUTORIALS; Database changed mysql> DROP TABLE tutorials_tbl Query OK, 0 rows affected (0.8 sec) mysql>
Dropping Tables Using PHP Script:
To drop an existing table in any database, you would need to use PHP function mysql_query(). You will pass its second argument with proper SQL command to drop a table.
Example:
<html> <head> <title>Creating MySQL Tables</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 tutorials_tbl"; mysql_select_db( 'TUTORIALS' ); $retval = mysql_query( $sql, $conn ); if(! $retval ) { die('Could not delete table: ' . mysql_error()); } echo "Table deleted successfully\n"; mysql_close($conn); ?> </body> </html>
