To delete data from a table, you use the MySQL DELETE statement. The following illustrates the syntax of the DELETE statement:

DELETE FROM table_name
WHERE condition;
In this statement:

First, specify the table from which you delete data.
Second, use a condition to specify which rows to delete in the WHERE clause. The DELETE statement will delete rows that match the condition,

public function deletedata(){	

	$this->db->where('id', 2);	
	$this->db->delete('table_name');

	}

DELETE FROM table_name
/* delete all from the table */
