zarif_Melika:

my table have about 6000 rows

Each of those 6000 rows must scan all 6000 rows, which results in (6000 * 6000) = 36000 rows scanned. That’s not trivial. And it’s on top of any other virtual column you have to calculate.

Perhaps find a way to store the computed value in a regular column rather than using a virtual column? Or move the computed column to a table with one row per vendor. The solution depends on what you’re trying to accomplish.

2- how to filter the table for 1 vendor that selected from vendor table in order to reduce calculation

slice don’t stop calculation i need to run that calculation when i need for only 1 vendor so it can be easy for the app to handle
