This past week I was given an SQL lab involving functions. My knowledge of SQL pre-dating this lab was minimal at best and am having a hard time getting my head around a particular function.

Four tables:

    You need to give it a try.
    Your main table would be Team, so you have to 

    select 
from team 
where Team1.teamID = your_parameter and Team1.year = your_year

    Since you don’t need details about the players, just amount, you can just join the Team1 table with playerTeam1 and count the number of records with a count function.

    If you needed the player’s details, you would need to join the other tables, but since it isn’t necessary you are fine with the only 2 tables I mentioned.
