Mapping SQL tables and Shuffle data ?

I am using an external data base view to map. This works fine where the records are inserted in the same order as whats on the source db.
Is their a Shuffle option. I need to import 2 columns and each has to match. For example let assume I am trying to do a movie ticket sales table.
Movie Name, Studio Name (so both has to match) are mapped from external source. Right now it works where col1 and and col2 mapes the source table..but in the same order. Their is no shuffle and random way to do it

I recommend you to use the SQL Statement generator as this will shuffle the data for you. You should be able to mix and match the SQL Statement Generator with the Map functionality, allowing you to only shuffle the columns you are interested in.
I hope this helps.

Ben,
Right now on both columns i am populating values usng SQL Statment Generator...how ever I cant find the MAP function .
It looks like we can refer to the table which we are trying to populate on a WHERE clause. So in what order is the data is generated. If I want 1000 records....do you go row by row or first fill the first column and then go to the second column

Here is what I am trying to do.
Lets say the first column on the generated table is First Name and this is read from another table. The second field on the generated table is last name, for this I need to make sure the data I generate match the first column.
I tried to do some thing like this but it did not work
Select OrginalTable.SecondCol
From OrginalTable,GeneratedTable
where GeneratedTable.FirstCol = OrginalTable.First Col.
