Find sum with MySQL SUM() and give aliases for column heading

MySQLMySQLi Database

For alias, use the following syntax wherein we are display an alias name −

select sum(yourColumnName) as anyAliasName from yourTableName;

Let us first create a table −

mysql> create table DemoTable1800
     (
     Salary int
     );
Query OK, 0 rows affected (0.00 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1800 values(18000);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1800 values(32000);
Query OK, 1 row affected (0.00 sec)
mysql> insert into DemoTable1800 values(50000);
Query OK, 1 row affected (0.00 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1800;

This will produce the following output −

+--------+
| Salary |
+--------+
|  18000 |
|  32000 |
|  50000 |
+--------+
3 rows in set (0.00 sec)

Here is the query find sum and set alias for column heading −

mysql> select sum(Salary) as Total from DemoTable1800;

This will produce the following output −

+--------+
| Total  |
+--------+
| 100000 |
+--------+
1 row in set (0.00 sec)
