MySQL query to set different combinations for values in a table?

Let us first create a table −

mysql> create table DemoTable622 (Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,Value1 int,Value2 int); Query OK, 0 rows affected (1.08 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable622(Value1,Value2) values(1000,1000); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable622(Value1,Value2) values(2000,3000); Query OK, 1 row affected (1.04 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable622;

This will produce the following output −

+----+--------+--------+ | Id | Value1 | Value2 | +----+--------+--------+ | 1 | 1000 | 1000 | | 2 | 2000 | 3000 | +----+--------+--------+ 2 rows in set (0.00 sec)

Here is the query to MySQL combinations −

mysql> select tbl1.Id,tbl2.Value1,tbl3.Value2 from DemoTable622 tbl1,DemoTable622 tbl2,DemoTable622 tbl3;

This will produce the following output −

+----+--------+--------+ | Id | Value1 | Value2 | +----+--------+--------+ | 1 | 1000 | 1000 | | 2 | 1000 | 1000 | | 1 | 2000 | 1000 | | 2 | 2000 | 1000 | | 1 | 1000 | 3000 | | 2 | 1000 | 3000 | | 1 | 2000 | 3000 | | 2 | 2000 | 3000 | +----+--------+--------+ 8 rows in set (0.01 sec)
