For some front-end tools, the INTO clause of an SQL statement may be used for variable assignment which violates the syntax of the INTO clause. Therefore, an INTO clause in the SQL statement with more than one variable will be commented.
For example:
select EMP_ID,
EMP_NAME
into a, b
from EMPLOYEE
select EMP_ID,
EMP_NAME /* into a, b */ /* Commented by SQL Optimizer*/
from EMPLOYEE
