Hi, I figured out the problem why results where not being returned
select * from dfs.vtucare.tbl_transactions as table1 join dfs.vtucare.tbl_products as table2 on LTRIM(RTRIM(table1.product_code)) = LTRIM(RTRIM(table2.product_code)) limit 1 A LTRIM and RTRIM on the join columns without any casting or conversion, solved the problem Best regards, Peter Edike Senior Software Engineer Interswitch Tel. | Mobile. | IP Phone.
