Okay, so I have this problem with my Fact Table. I need it to automatically be filled when a new data is entered on all the other tables in the database which has a foreign key on my Fact Table. In my stored procedure, I compiled all the insert statements I have and at the end, since I also want to update my Fact Table, I place this query:

INSERT INTO Fact (AccountID, ExpenseID, DateTimeID, InventoryID)
VALUES (@AccountID, 
        (SELECT ExpenseID FROM Expenses WHERE WaterBill = @WaterBill AND ElectricBill = @ElectricBill AND OfficeRent = @OfficeRent,
        SELECT DateTimeID FROM DateTime WHERE MonthNo = @MonthNo AND Date = @Date AND Year = @Year AND Time = @Time AND Day = @Day AND DayNo = @DayNo,
        SELECT InventoryID FROM Inventory WHERE ProductInID = @ProductInID AND ProductOutID = @ProductOutID)

However, I get an error with the following message:

Subqueries are not allowed in this context. Only scalar expressions are allowed.

Can anybody please help me? Thanks a lot. 🙂

    ALTER PROCEDURE [dbo].[ExpenseListInsert]

    Assuming that the sub queries can each return only one record this should work

    DECLARE @ExpenseID int, @DateTimeID int, @InventoryID int


SELECT @ExpenseID= ExpenseID FROM Expenses WHERE WaterBill = @WaterBill AND ElectricBill = @ElectricBill AND OfficeRent = @OfficeRent

SELECT @DateTimeID = DateTimeID FROM DateTime WHERE MonthNo = @MonthNo AND Date = @Date AND Year = @Year AND Time = @Time AND Day = @Day AND DayNo = @DayNo

SELECT @InventoryID = InventoryID FROM Inventory WHERE ProductInID = @ProductInID AND ProductOutID = @ProductOutID

INSERT INTO Fact (AccountID, ExpenseID, DateTimeID, InventoryID)
VALUES (@AccountID, @ExpenseID, @DateTimeID, @InventoryID)
