Display two different columns from two different tables with ORDER BY?
For this, you can use UNION along with the ORDER BY clause. Let us first create a table −
mysql> create table DemoTable1 ( Amount int ); Query OK, 0 rows affected (0.63 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1 values(234); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable1 values(567); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable1 values(134); Query OK, 1 row affected (0.43 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable1;
This will produce the following output −
+--------+ | Amount | +--------+ | 234 | | 567 | | 134 | +--------+ 3 rows in set (0.00 sec)
Here is the query to create the second table −
mysql> create table DemoTable2 ( Price int ); Query OK, 0 rows affected (0.73 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable2 values(134); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable2 values(775); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable2 values(121); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable2 values(882); Query OK, 1 row affected (0.09 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable2;
This will produce the following output −
+-------+ | Price | +-------+ | 134 | | 775 | | 121 | | 882 | +-------+ 4 rows in set (0.00 sec)
Following is the query to display two different columns from two different tables with ORDER BY −
mysql> select distinct Amount from DemoTable1 UNION select distinct Price from DemoTable2 order by Amount;
This will produce the following output −
+--------+ | Amount | +--------+ | 121 | | 134 | | 234 | | 567 | | 775 | | 882 | +--------+ 6 rows in set (0.00 sec)
