You can use:

$col["dbname"] = "store_id";

This will be used in WHERE clause.

Hi Abu Ghufran,

Thanks for your assistance.
But I doesn't find out the right solution, I used
$col["dbname"] = "store_id"; but I want to show the store name in grid listing instead of store_id.

I want store name in grid listing and editing filtration with store_id

Thanks
Narinder Singh
