Question

我在SQL Server 2005中编写了以下存储过程，并收到错误消息：

Msg 102，Level 15，State 1，Procedure sp_InsertCustTrans，Line 12
＆＃39; @ TrID＆＃39;附近的语法不正确。

我的存储过程是：

ALTER PROCEDURE [dbo].[sp_InsertCustTrans] 
-- Add the parameters for the stored procedure here
@CuID int, @TrType nvarchar(10), @TrAmt int
AS
BEGIN
SET NOCOUNT ON;
    declare @TrID int;
    Select @TrID = MAX(TransactionID) from CustTrans;
    if Isnull(@TrID)
        @TrID = @TrID + 1
    else
        @TrID = 1

-- Insert statements for procedure here
if (@TrType = 'Deposit')
    begin
        INSERT INTO CustTrans (TransactionID, TransactionDate, CustID, TransactonType, CreditAmount)
            Values(@TrID, GetDate(), @CuID, @TrType, @TrAmt);
    end
else
    begin
        INSERT INTO CustTrans (TransactionID, TransactionDate, CustID, TransactonType, DebitAmount)
            Values(@TrID, GetDate(), @CuID, @TrType, @TrAmt);
    end
END
GO

所有作业操作必须以关键字set开头。

Set @TrID = @TrID + 1

Ivan指出，你也正在使用IsNull。正确的用法是：

If @TrID Is Null

Msg 102，Level 15，State 1，
