Add_Group_Column comes after the using of the Add_Group_Row.
When We are going to create a non-query based record group
the first create the record group's row then make the column
one by one. It acts like a virtual record group.

In design time it has no existence , so just at runtime it
is created and holds the chunk of data.

in user parameter property we have list of values.can we write select query for binding? for example:: select empno from emp where deptno=:deptnum :deptnum is first parameter it displays distinct dept nos. if i do like this it is giving error:: bind variables are not allowed in the select statement
