Hello Every one seeing this message,
As i am using my database about a week ago and i am creating a software for stock management for my store. And I had 5 costumer with me to use this database's i though that if a crate a login interface where if a customer login then he/she can only see her or only data her data. For e.g. my 5 customer are a ,b ,c and d. And i am saying that if a customer is login then a customer can see only his data. And to separate the customer i have their different customer id. So for that what i need to do. For eg i have a database which i had posted in this message.
