I want to use custom SQL to limit the records by the excel file join. Please let me know how can I do it. I do have an excel file with product code consisting of 200 rows, However, my database table has a products column close to 1 million.

I want to join on product column and limit it to those 200 products alone while joining. I feel just doing an inner join on the product column is inefficient. Please let me know how I can perform the join limit. Is it possible?
