Cube Operator

When we are using more than 10 columns in cube operator it is throwing error that maxiimum limit is 10.
but it is mandatory for my project to use more than 10 columns.
So could any one tell how to do this.
If not at all possible by using cube operator how else can this be done to get the same result

The only way to do this is to generate the query with the necessary GROUP BY clauses yourself. The sheer number of combinations that you need to take care of will be huge. You could write a stored procedure or client side script that can generate a query for each combination of GROUP BY and UNION them together to get the same results. It almost seems like this is more suited for OLAP.
