Salable Quantity is showing zero in product grid magento 2?

Reason : Why this happen, when you import database the view may missing, not enough permission to create database

as Because CREATE ALGORITHM=UNDEFINED DEFINER needs super privilege to make this work done

Solution :

IN DataBase There was two type 1> Tables and 2> Views The issue is possibly caused When Import/Export DataBase Views Was Not Created in magento 2.3 So Create Views and inventory_stock_1 table In DataBase.
