SQL Server过程没有返回任何结果

Question

好的,所以我的SQL Server 2005数据库中有以下过程.我想弄清楚为什么它没有给我任何结果.尝试访问它的用户是管理员,但我也尝试过与其他用户访问它,但我仍然没有得到任何结果.Bond在Bond表的基本查询中返回.我只想弄清楚为什么这没有结果.任何帮助表示赞赏.

ALTER PROCEDURE dbo.GetBondAmounts
(
    @Username varchar(20)
)
AS
DECLARE @Admin AS bit
SELECT @Admin = Admin FROM Users WHERE Username = @Username
if(@Admin = 1)
BEGIN
    RETURN
    SELECT Bond.ID, SUM(Charge.BondAmount) + SUM(ChargeWithoutPower.BondAmount) Amount,
    SUM(Charge.BondPremium) + SUM(ChargeWithoutPower.BondPremium) + SUM(Forfeiture.AmountPaid)
    + SUM(Forfeiture.CostOfApprehension) - SUM(Payment.Amount) - SUM(BalanceForgiveness.AmountForgiven) Balance
    FROM Bond LEFT OUTER JOIN Payment ON Bond.ID = Payment.Bond
    LEFT OUTER JOIN BalanceForgiveness ON Bond.ID = BalanceForgiveness.BondID
    LEFT OUTER JOIN Powers ON Bond.ID = Powers.Bond
    LEFT OUTER JOIN Charge ON Powers.Surety = Charge.PowerSurety
    AND Powers.PowerPrefix = Charge.PowerPrefix AND Powers.PowerNumber = Charge.PowerNumber
    LEFT OUTER JOIN ChargeWithoutPower ON Bond.ID = ChargeWithoutPower.ID
    LEFT OUTER JOIN Forfeiture ON Bond.ID = Forfeiture.Bond
    LEFT OUTER JOIN BondFee ON Bond.ID = BondFee.Bond
    GROUP BY Bond.ID
END
ELSE
BEGIN
    RETURN
    SELECT Bond.ID, SUM(Charge.BondAmount) + SUM(ChargeWithoutPower.BondAmount) Amount,
    SUM(Charge.BondPremium) + SUM(ChargeWithoutPower.BondPremium) + SUM(Forfeiture.AmountPaid)
    + SUM(Forfeiture.CostOfApprehension) - SUM(Payment.Amount) - SUM(BalanceForgiveness.AmountForgiven) Balance
    FROM Bond LEFT OUTER JOIN UserAgency ON Bond.Agency = UserAgency.Agency
    LEFT OUTER JOIN Payment ON Bond.ID = Payment.Bond
    LEFT OUTER JOIN BalanceForgiveness ON Bond.ID = BalanceForgiveness.BondID
    LEFT OUTER JOIN Powers ON Bond.ID = Powers.Bond
    LEFT OUTER JOIN Charge ON Powers.Surety = Charge.PowerSurety
    AND Powers.PowerPrefix = Charge.PowerPrefix AND Powers.PowerNumber = Charge.PowerNumber
    LEFT OUTER JOIN ChargeWithoutPower ON Bond.ID = ChargeWithoutPower.ID
    LEFT OUTER JOIN Forfeiture ON Bond.ID = Forfeiture.Bond
    LEFT OUTER JOIN BondFee ON Bond.ID = BondFee.Bond
    WHERE UserAgency.Username = @Username
    GROUP BY Bond.ID
END

我使用C#访问此过程如下:

bondingData.Merge(getBondAmountsAdapter.GetData(currentUser.Username));

这是我添加的测试行,看看是否返回了任何结果:

MessageBox.Show("Bond Count A: " + bondingData.Bond.Count.ToString() + "\r\nBond Count B: " + bondingData.GetBondAmounts.Count.ToString());

当我运行它时,这是我收到的结果:

Bond Count A: 1
Bond Count B: 0

好的,所以这是我的问题的解决方案:

ALTER PROCEDURE dbo.GetBondAmounts
(
    @Username varchar(20)
)
AS
    SELECT Bond.ID, dbo.GetBondTotal(Bond.ID) Total, dbo.GetBondBalance(Bond.ID) Balance
    FROM Bond LEFT OUTER JOIN
    UserAgency ON Bond.Agency = UserAgency.Agency
    WHERE UserAgency.Username = @Username
    OR EXISTS (SELECT * FROM Users WHERE Username = @Username AND Admin = 1)
    GROUP BY Bond.ID

这些是在此处调用的2个存储函数.不确定它的效率如何,但不会有那么多的付款或任何与个人债券相关的东西.当程序有大量记录时,它可能会变慢.

功能1:

ALTER FUNCTION dbo.GetBondTotal
(
@BondID bigint
)
RETURNS money
AS
BEGIN
    DECLARE @PowersTotal AS money;
    DECLARE @ChargesTotal AS money;
    DECLARE @BondFeeTotal AS money;
    DECLARE @ForfeitureCosts AS money;
    SELECT @PowersTotal = SUM(BondPremium)
    FROM Charge INNER JOIN Powers ON Charge.PowerSurety = Powers.Surety
    AND Charge.PowerPrefix = Powers.PowerPrefix
    AND Charge.PowerNumber = Powers.PowerNumber
    WHERE Bond = @BondID
    SELECT @ChargesTotal = SUM(BondPremium)
    FROM ChargeWithoutPower
    WHERE BondID = @BondID
    SELECT @BondFeeTotal = SUM(Amount)
    FROM BondFee WHERE Bond = @BondID
    SELECT @ForfeitureCosts = SUM(CostOfApprehension) + SUM(AmountPaid)
    FROM Forfeiture WHERE Bond = @BondID
    RETURN @PowersTotal + @ChargesTotal + @BondFeeTotal + @ForfeitureCosts
END

功能2:

ALTER FUNCTION dbo.GetBondBalance
(
@BondID bigint
)
RETURNS MONEY
AS
    BEGIN
    DECLARE @PowersTotal AS money;
    DECLARE @ChargesTotal AS money;
    DECLARE @BondFeeTotal AS money;
    DECLARE @ForfeitureCosts AS money;
    DECLARE @PaymentTotal AS money;
    DECLARE @AmountForgiven AS money;
    SELECT @PowersTotal = SUM(BondPremium)
    FROM Charge INNER JOIN Powers ON Charge.PowerSurety = Powers.Surety
    AND Charge.PowerPrefix = Powers.PowerPrefix
    AND Charge.PowerNumber = Powers.PowerNumber
    WHERE Bond = @BondID
    SELECT @ChargesTotal = SUM(BondPremium)
    FROM ChargeWithoutPower
    WHERE BondID = @BondID
    SELECT @BondFeeTotal = SUM(Amount)
    FROM BondFee WHERE Bond = @BondID
    SELECT @ForfeitureCosts = SUM(CostOfApprehension) + SUM(AmountPaid)
    FROM Forfeiture WHERE Bond = @BondID
    SELECT @PaymentTotal = SUM(Amount)
    FROM Payment WHERE Bond = @BondID
    SELECT @AmountForgiven = SUM(AmountForgiven)
    FROM BalanceForgiveness WHERE BondID = @BondID
    RETURN @PowersTotal + @ChargesTotal + @BondFeeTotal + @ForfeitureCosts - @PaymentTotal - @AmountForgiven
END

我相信我会创建第三个功能来支付金额(Charge.Amount + ChargeWithoutPower.Amount)

Answer 1

你RETURN在每个部分的开头都有一个声明.

一旦命中此语句,查询将立即返回,因此SELECT将不会执行,也不会返回任何内容.

要解决此问题 - 删除RETURN语句.
