    select count with NO children?

    I have a USER table with a child ACCOUNT table

    USER <--- ACCOUNT(fk USER_ID)

    I want to find all the users that have NO accounts?

    I can find users that have 1,2,3,N accounts, just not 0 accounts!

    help!

    Have you heard about inline views?
    I would count from USER where the USER does not exists on ACCOUNT.

    Show us your best effort.
