If you have to join these tables together the complexity of the resultant query should be irrelevant.

I have no clue what you mean when you indicate "5 records | 10 records" in the final result. I'm tempted to ask you leading questions but instead am going to ask that you consider your goal more closely and be more explicit in your description/request. If you just want to go and play with it you can consider two possible options: SELECT * FROM tbl1 CROSS JOIN tbl2 --(this will return X times Y rows - or 10 times 5 = 50) or <not valid SQL, just an example> SELECT * FROM (SELECT row_number, * FROM tbl1) t1 FULL OUTER JOIN (SELECT row_number, * FROM tbl2) t2 USING (row_number) -- this will return 10 rows with 5 of them containing NULL values for t1 columns where t2 has row numbers not existing in t1. What you are doing, by the example given, is wrong. Proposing an alternative is impossible since you have not explained WHY you feel you need to do this or WHAT you are actually trying to accomplish.
