Question

以下存储过程给出了上述错误。但是，当我将每个部分作为一个简单的查询运行时，它运行正常。我没看到什么？它应该得到不同班次的部门数据。

ALTER PROCEDURE [dbo].[DataByDepartment] 
(
 @referenceDateTime DATETIME
,@shiftsBackward INT
,@shiftsForward INT
,@departmentID int 
)AS BEGIN
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
SET NOCOUNT ON;

DECLARE @referenceStartDate DATETIME;
DECLARE @referenceEndDate DATETIME;

SET @referenceDateTime=COALESCE(@referenceDateTime,CURRENT_TIMESTAMP);
SET @shiftsBackward=COALESCE(@shiftsBackward,2);
SET @shiftsForward=COALESCE(@shiftsForward,1);

SELECT 
    @referenceStartDate=MIN(StartDateTime)
    ,@referenceEndDate=MAX(EndDateTime)
FROM dbo.GetShiftsDateTime(@referenceDateTime,@shiftsBackward,@shiftsForward,2);


WITH DataByStockCode AS

(
    SELECT D.StockCode          
         ,D.EntryDate+CAST(STUFF(STUFF(STUFF(RIGHT('00000000'+CAST(D.TrnTime AS VARCHAR(10)),8),3,0,':'),6,0,':'),9,0,':') AS TIME) AS DateTime
        ,IM.TrnQty AS Qty
        ,FD.AlphaValue
    FROM [dbo].[Data] AS D
    INNER JOIN [dbo].[FormData] as FD on 
    D.StockCode=FD.KeyField         
    WHERE (             
            (D.TrnYear>=(YEAR(CURRENT_TIMESTAMP)-1))
            AND
            (D.TrnMonth>=1)
            AND
            (D.EntryDate>=CAST(@referenceStartDate AS DATE))
            AND 
            (D.EntryDate<=CAST(@referenceEndDate AS DATE))              
            AND

        (BSC.DateTime>=GWSFRDT.StartDateTime)
        AND
        (BSC.DateTime<=GWSFRDT.EndDateTime)
    )
)
SELECT 
    BBS.ShiftSequence
    ,BBS.DateTime
    ,BBS.AlphaValue
    ,sum(BBS.Qty) as TotalQTY
    ,BBS.ShiftStart

Group BY ShiftSequence,DateTime,AlphaValue,Qty,ShiftStart

Answer 1

我认为错误来自这一行：

D.EntryDate+CAST(STUFF(STUFF(STUFF(RIGHT('00000000'+CAST(D.TrnTime AS VARCHAR(10)),8),3,0,':'),6,0,':'),9,0,':') AS TIME) AS DateTime

我假设EntryDate是一个日期时间。加号被解释为带有日期时间的加法，因此“+”之后的表达式被隐式转换为int，因为您无法将时间值添加到日期时间值。尝试

DECLARE @time time = '12:00'
SELECT GETDATE() + @time

验证。

假设TrnTime是一个时间字段，只需将其转换为日期时间：

D.EntryDate+CAST(D.TrnTime AS DATETIME) AS DateTime

它会正常工作。

转换varchar值'4K0400时转换失败
