SQL Server 삽입 쿼리 테이블에 삽입합니다

Question

괜찮아, 그래서 나는이 문제가 내 사실 테이블에 문제가있다.새 데이터가 내 사실 테이블에 외래 키가있는 데이터베이스의 다른 모든 테이블에 새 데이터가 입력되면 자동으로 채워질 수 있습니다.내 저장 프로 시저에서는 제가 가진 모든 삽입문을 작성했으며 결국에도 내 사실 테이블을 업데이트하고 싶기 때문에이 쿼리를 배치합니다.

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)

.

그러나 다음 메시지와 함께 오류가 발생합니다.

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

아무도 나를 도와 주실 수 있습니까?고마워.:)

나의 완전한 절차 :

    ALTER PROCEDURE [dbo].[ExpenseListInsert]
    @AccountID char(6),
    @ExpenseID int,
    @DateTimeID int,
    @InventoryID int,
    @WaterBill decimal(19, 4),
    @ElectricBill decimal(19, 4),
    @OfficeRent decimal(19, 4),
    @Miscellaneous decimal(19, 4),
    @ProductsExpense decimal(19, 4),
    @Subtotal decimal(19, 4),
    @ProductInID int,
    @ProductOutID int,
    @Product30001 int,
    @Product30002 int,
    @Product30003 int,
    @MonthNo int,
    @Date int,
    @Year int,
    @Time char(11),
    @Day char(10),
    @DayNo int
AS
    INSERT INTO Expenses (WaterBill, ElectricBill, OfficeRent, Miscellaneous, ProductsExpense, Subtotal)
    VALUES(@WaterBill, @ElectricBill, @OfficeRent, @Miscellaneous, @ProductsExpense, @Subtotal)

    INSERT INTO ProductIn (ProductInID, Product30001, Product30002, Product30003)
    VALUES(@ProductInID, @Product30001, @Product30002, @Product30003)

    INSERT INTO ProductOut (ProductOutID, Product30001, Product30002, Product30003)
    VALUES(@ProductOutID, '0', '0', '0')

    INSERT INTO Inventory (ProductInID, ProductOutID)
    VALUES (@ProductInID, @ProductOutID) 

    INSERT INTO DateTime (MonthNo, Date, Year, Time, Day, DayNo)
    VALUES (@MonthNo, @Date, @Year, @Time, @Day, @DayNo)

    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)
RETURN

Answer 1

서브 쿼리가 각각 하나의 레코드 만 반환 할 수 있다고 가정하면

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)

바닐라 삽입물로 하위 쿼리를 수행 할 수 없으며 삽입을해야합니다 ... 선택 :

INSERT INTO [Fact] (AccountID, ExpenseID, DateTimeID, InventoryID)
SELECT @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)

.

가능한 성능 병 목에 대한 실행 계획을 살펴보고 비용, 날짜 시간 및 인벤토리 테이블의 인덱스를 살펴 보겠습니다.

Answer 3

쿼리를 변경하십시오.

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