Question

I am having some trouble building the query I need to return the AccountID from the FamilyAccountDetails table where the Family account has at least one child(a child is where the AccountDetails.AccountID equals the FamilyAccountDetails.AccountID) that has a HoldFlag = 0.

AccountDetails
EntID  |HoldFlag|AccountID|StatusFlag

FamilyAccountDetails
EntID|FamilyAccountID|AccountID|StatusFlag

SQL:

      Select FD.AccountID, FD.FamilyAccountId 
from Test2TMAdvisor5.dbo.FamilyAccountDetails FD
      where FD.EnterpriseId = 'TestDan'
      and AccountId in (Select AccountId from Test2TMAdvisor5.dbo.AccountDetails AD where Ad.AccountID = FD.AccountId and ad.HoldFlag =0)

Answer 1

SELECT
    FD.[AccountID]
    ,FD.[FamilyAccountId] 
FROM
    FamilyAccountDetails FD
WHERE
    FD.[EnterpriseId] = 'TestDan'
    AND EXISTS 
        (
        SELECT 
            * 
        FROM 
            AccountDetails AD
        WHERE 
            AD.[AccountID] = FD.[AccountId] 
            AND AD.[HoldFlag] = 0
        )
