   )

I formatted this using an online formatter to make it easier to see. You have 2 inner joins and 1 left join on queries we do not know. So it may be hard to answer without understanding those queries. Can you post a sample db?

You are joining on data field to data field. Normally, a join would be from data field to PK. Data field to data field almost always leads to "duplication".

An Inner Join (which is what you have) returns a row from tbl1 for each match in tbl2 so if there are 9 records for PSA-063 in tbl1 and 4 records with that value in tbl2, then you will end up with 9 * 4 or 36 rows in the result set for PSA-063.

There is either something wrong with your data or the logic of your join.
