如何将这两个查询放在SQL术语中?

I have a scenario where upon a person registering a new community I want them to automatically become a member of that community.

I have 3 tables:

users id | user_email | user_password | user_name

communities id | name | code | admin

community_playes community_id | player_id

Upon the community being created I immediately need to run the following MySQL queries so that person becomes a member of said community:

1) To get community_id from table communities where admin = email and put into table community_players, community_id

2) To get id from table users where user_email = email and put into table community_players, player_id

I already have email as a variable.

My aim is to populate the community_players table with a new record containing the id of the user, and the community_id of the newly created community.

What would be the SQL statement for this? I have no experience in SQL.
