The backend application uses passport's local policy to verify that the user exists/that the username and password are correct by connecting to mongoDB. Once confirmed, I use passport's serialization and deserialization functions to maintain the login session

Nested queries run fine in SQLServer, but don't know how to implement it in MySQL. Limit query: Select*fromcustomerslimit
