I have 2 tables

commands

and

user_access

how can I make a policy so that when selecting from the

commands

column, users will only be able to retrieve the rows that have the same

server_id

value to what has been specified in the

user_access

table linked with their

user_id

. The

commands

table has the columns

id

and

server_id

The

user_access

table has the columns

id

,

user_id

and

server_id
