How can I allow users sql access to a table limited to certain rows?

Question

I\'m building an stock exchange simulation game. I have a table called \'Market_data\' and in the game players simulate being in particular dates and are allowed to use SQL

Answer 1

The basic way would be :

-> Prevent that user (or group) from accessing the base table.

-> Define a view on top of that table that shows only the rows these users are supposed to see.

-> Give those users SELECT permission on the view.

-> And you can also use SQL Encryption,Decryption and Hashing concept.
