I’m very new to SQL and I’m creating a Superhero database with HEROES(Id, name,…) VILLAINS(…) TEAM(…) etc… and I want to grant access to update/select etc. of specific teams to the team leader (e.g. Superman – Justice League).
Obviously I don’t want to grant team leaders access to update the whole table, only the tuple in the table that matches the id assigned to them and the team.
I have written the code below based on the examples of GRANT access rules from lecture slides and online but I haven’t implemented it yet so am unsure if it’s valid or even works.
Given a Hero and a team e.g. Superman, Justice League (/w id = 1001)
GRANT UPDATE ON TEAMS WHERE team_id = 1001 TO Superman WITH GRANT OPTION;
does this code correctly give Superman access to only the Justice League team?
if not, how can it be improved?
