Syntax error Display two different columns from two different tables with ORDER BY?

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)
