    Question Unanswered: Extracting Partial Data in Access

    Hullo everyone. Thanks for the help already. However I have problem that I don't how to deal with and Ii request your help. I have an access database project I'm working on. It'a all about managing pupil's pocket money/upkeep while at school. I have three tables that I need to extract data from in order to determine a pupil's balance as time goes by. These tables are: PupilDetails, PayOut and tblReload. To determine a pupil's balance, I need to extract the AmountBF and AmountReceived from PupilDetails, AmountReloaded from tblReload, and the rest of the information from the PayOut table. I need to extract data from all these three tables. I use the field univID to connect all the three of them. I've tried the best I can to do it but the query returns completely nothing in case I query a univID that either has no reload made for that particular term, or payout made made to it in that same particular term. Since it's not a must to withdraw one's pocket money, and also since it's very possible that a pupil may not reload more money to his/her account, I need the query to return the AmountBF and the AmountReceived from that pupil for that particular because it exists and so it's his/her available/actual balance until any payouts or reloads are made. I found it easier to determine a pupil's balance using a report that's based on a query; but since the report won't return anything if the query returns nothing, It's flawed now. Please help me out.

    What's the SQL expression of the query you tried and does not work?
    Have a nice day!

    Seems you only needed 2 tables. pupil and transaction.
    Trans table would record EVERY transaction spent (and maybe pupil balance before)
    Pupil.balance would then decrease with every trans.

    why a 3rd table?
