Deleting a Database

If a database is no longer required then it can be deleted forever. You can use pass an SQL command to mysql_query to delete a database.

Example

Try out following example to drop a database.

<?php
   $dbhost = 'localhost:3036';
   $dbuser = 'root';
   $dbpass = 'rootpassword';
   $conn = mysql_connect($dbhost, $dbuser, $dbpass);
   
   if(! $conn ) {
      die('Could not connect: ' . mysql_error());
   }
   
   $sql = 'DROP DATABASE test_db';
   $retval = mysql_query( $sql, $conn );
   
   if(! $retval ) {
      die('Could not delete database db_test: ' . mysql_error());
   }
   
   echo "Database deleted successfully\n";
   
   mysql_close($conn);
?>

WARNING − its very dangerous to delete a database and any table. So before deleting any table or database you should make sure you are doing everything intentionally.

Deleting a Table

Its again a matter of issuing one SQL command through mysql_query function to delete any database table. But be very careful while using this command because by doing so you can delete some important information you have in your table.

Example

Try out following example to drop a table −

<?php
   $dbhost = 'localhost:3036';
   $dbuser = 'root';
   $dbpass = 'rootpassword';
   $conn = mysql_connect($dbhost, $dbuser, $dbpass);
   
   if(! $conn ) {
      die('Could not connect: ' . mysql_error());
   }
   
   $sql = 'DROP TABLE employee';
   $retval = mysql_query( $sql, $conn );
   
   if(! $retval ) {
      die('Could not delete table employee: ' . mysql_error());
   }
   
   echo "Table deleted successfully\n";
   
   mysql_close($conn);
?>
