Implement a MySQL Void Query that does nothing
Let us first create a table −
mysql> create table DemoTable(Name varchar(100)); Query OK, 0 rows affected (0.47 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('Chris');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('Sam');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable values('Robert');
Query OK, 1 row affected (0.37 sec)
mysql> insert into DemoTable values('Mike');
Query OK, 1 row affected (0.09 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+--------+ | Name | +--------+ | Chris | | Sam | | Robert | | Mike | +--------+ 4 rows in set (0.00 sec)
Following is the query for MySQL void −
mysql> select *from DemoTable limit 0; Empty set (0.00 sec)
Above, the result is Empty set and the query does nothing.
