Hi, is it possible to preset a query once an account is logged in the page?

For example: we have a database containing all of our products, in this database there is a column in which is shown the name of the customers. We want the client to see only the product we sold them as soon as they open the page. We don't want to show them other product sold to other client. So I think that there must be a personalized query....

How can I do it? 

Thank you.

Hi Bogdan, 

I did not explain well, I would like to delete the entire row if the name of the customer who has access to that page does not appear in the column.
Let me make an example to be clearer:

Color                Customer
red                    Cristina
green                Cristina
yellow                Federica

I do not want Cristina to see the row where the name Federica appears.

So, Cristina, logging to her page will see:

Color                Customer
red                    Cristina
green                Cristina

Thank you, this is what I was looking for! :)
