Perform MySQL SELECT INTO user-defined variable
Let us first create a table −
mysql> create table DemoTable1483 -> ( -> Salary int -> ); Query OK, 0 rows affected (0.41 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1483 values(100); Query OK, 1 row affected (0.17 sec) mysql> insert into DemoTable1483 values(500); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1483 values(400); Query OK, 1 row affected (0.12 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1483;
This will produce the following output −
+--------+ | Salary | +--------+ | 100 | | 500 | | 400 | +--------+ 3 rows in set (0.00 sec)
Following is the query to perform select into user-defined variable −
mysql> select sum(Salary) into @TotalSalary from DemoTable1483; Query OK, 1 row affected (0.00 sec)
Now display the value of variable −
mysql> select @TotalSalary;
