Question

我有以下代码

SELECT dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR AS [EHP Code], 
       dbo.COL_TBL_VCOURSE_NEW.TNG_NA AS [Course Title],
       dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD & dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD AS [Course Owner], 
       dbo.COL_TBL_VCOURSE_TYP.TNG_DESC AS [TYPE OF TRAINING], 
       dbo.COL_V_Cost_GEMS_Detail.JOB_FCT_CD, 
       dbo.COL_V_Cost_GEMS_Detail.JOB_GRP_CD, 
       dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM + dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM AS [Total Cost], 
       SUM(dbo.COL_V_Cost_GEMS_Detail.STUDENTS) AS SumOfSTUDENTS, 
       SUM(dbo.COL_V_Cost_GEMS_Detail.INSTRUCTORS) AS SumOfINSTRUCTORS,
       SUM(dbo.COL_V_Cost_GEMS_Detail.ST_HOURS_SUM) AS ST_HOURS,
       SUM(dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM) AS ST_COST, 
       SUM(dbo.COL_V_Cost_GEMS_Detail.IN_HOURS_SUM) AS IN_HOURS, 
       SUM(dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM) AS IN_COST
FROM  dbo.COL_V_Cost_GEMS_Detail INNER JOIN  dbo.COL_TBL_VCOURSE_NEW 
      ON dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR = dbo.COL_TBL_VCOURSE_NEW.TNG_SYS_NR       
      INNER JOIN dbo.COL_TBL_VCOURSE_TYP 
      ON dbo.COL_TBL_VCOURSE_NEW.TNG_MDA_TYP_CD = dbo.COL_TBL_VCOURSE_TYP.TNG_TYP
WHERE (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%12%') 
       AND 
       (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%13%') 
       AND 
       (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2706%') 
       AND 
       (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2707%')
       AND 
       (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2331%')
GROUP BY dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR, 
         dbo.COL_TBL_VCOURSE_NEW.TNG_NA, 
         dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD & dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD,         
         dbo.COL_TBL_VCOURSE_TYP.TNG_DESC, 
         dbo.COL_V_Cost_GEMS_Detail.JOB_FCT_CD,
         dbo.COL_V_Cost_GEMS_Detail.JOB_GRP_CD, 
         dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM +  
         dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM

我一直收到错误

Msg 402, Level 16, State 1, Line 1
The data types nvarchar and nvarchar are incompatible in the boolean AND operator.

无论我做出什么改变，我似乎都无法摆脱这个错误。起初我以为它会是数据类型，但它们都很好，我认为它是一些符号，但替换它们也不起作用。

Answer 1

好像你有一个＆amp;试着改变它！

Answer 2

我删除了＆amp ;.如果这是否有效，请尝试此操作。

SELECT dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR AS [EHP Code], dbo.COL_TBL_VCOURSE_NEW.TNG_NA AS [Course Title], 
           dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD, dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD AS [Course Owner], 
           dbo.COL_TBL_VCOURSE_TYP.TNG_DESC AS [TYPE OF TRAINING], dbo.COL_V_Cost_GEMS_Detail.JOB_FCT_CD, dbo.COL_V_Cost_GEMS_Detail.JOB_GRP_CD, 
           dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM + dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM AS [Total Cost], SUM(dbo.COL_V_Cost_GEMS_Detail.STUDENTS) 
           AS SumOfSTUDENTS, SUM(dbo.COL_V_Cost_GEMS_Detail.INSTRUCTORS) AS SumOfINSTRUCTORS, SUM(dbo.COL_V_Cost_GEMS_Detail.ST_HOURS_SUM) 
           AS ST_HOURS, SUM(dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM) AS ST_COST, SUM(dbo.COL_V_Cost_GEMS_Detail.IN_HOURS_SUM) AS IN_HOURS, 
           SUM(dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM) AS IN_COST
FROM  dbo.COL_V_Cost_GEMS_Detail INNER JOIN
           dbo.COL_TBL_VCOURSE_NEW ON dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR = dbo.COL_TBL_VCOURSE_NEW.TNG_SYS_NR INNER JOIN
           dbo.COL_TBL_VCOURSE_TYP ON dbo.COL_TBL_VCOURSE_NEW.TNG_MDA_TYP_CD = dbo.COL_TBL_VCOURSE_TYP.TNG_TYP
WHERE (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%12%') AND (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%13%') AND 
           (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2706%') AND (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2707%') AND 
           (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2331%')
GROUP BY dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR, dbo.COL_TBL_VCOURSE_NEW.TNG_NA, 
           dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD, dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD, dbo.COL_TBL_VCOURSE_TYP.TNG_DESC, 
           dbo.COL_V_Cost_GEMS_Detail.JOB_FCT_CD, dbo.COL_V_Cost_GEMS_Detail.JOB_GRP_CD, 
           dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM + dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM

或者你可能想要总和：

SELECT dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR AS [EHP Code], dbo.COL_TBL_VCOURSE_NEW.TNG_NA AS [Course Title], 
               dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD + dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD AS [Course Owner], 
               dbo.COL_TBL_VCOURSE_TYP.TNG_DESC AS [TYPE OF TRAINING], dbo.COL_V_Cost_GEMS_Detail.JOB_FCT_CD, dbo.COL_V_Cost_GEMS_Detail.JOB_GRP_CD, 
               dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM + dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM AS [Total Cost], SUM(dbo.COL_V_Cost_GEMS_Detail.STUDENTS) 
               AS SumOfSTUDENTS, SUM(dbo.COL_V_Cost_GEMS_Detail.INSTRUCTORS) AS SumOfINSTRUCTORS, SUM(dbo.COL_V_Cost_GEMS_Detail.ST_HOURS_SUM) 
               AS ST_HOURS, SUM(dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM) AS ST_COST, SUM(dbo.COL_V_Cost_GEMS_Detail.IN_HOURS_SUM) AS IN_HOURS, 
               SUM(dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM) AS IN_COST
    FROM  dbo.COL_V_Cost_GEMS_Detail INNER JOIN
               dbo.COL_TBL_VCOURSE_NEW ON dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR = dbo.COL_TBL_VCOURSE_NEW.TNG_SYS_NR INNER JOIN
               dbo.COL_TBL_VCOURSE_TYP ON dbo.COL_TBL_VCOURSE_NEW.TNG_MDA_TYP_CD = dbo.COL_TBL_VCOURSE_TYP.TNG_TYP
    WHERE (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%12%') AND (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%13%') AND 
               (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2706%') AND (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2707%') AND 
               (dbo.COL_V_Cost_GEMS_Detail.RRDD NOT LIKE '%2331%')
    GROUP BY dbo.COL_V_Cost_GEMS_Detail.TNG_SYS_NR, dbo.COL_TBL_VCOURSE_NEW.TNG_NA, 
               dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD + dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD, dbo.COL_TBL_VCOURSE_TYP.TNG_DESC, 
               dbo.COL_V_Cost_GEMS_Detail.JOB_FCT_CD, dbo.COL_V_Cost_GEMS_Detail.JOB_GRP_CD, 
               dbo.COL_V_Cost_GEMS_Detail.ST_COST_SUM + dbo.COL_V_Cost_GEMS_Detail.IN_COST_SUM

Answer 3

您正在使用& Bitwise operator来连接字符串。 String concatenation在SQL-Server中使用+（或者您可以使用SQL-Server 2012，您可以使用CONCAT函数）

改变这个：

dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD & dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD,

要

dbo.COL_TBL_VCOURSE_NEW.FCT_TYP_CD + dbo.COL_TBL_VCOURSE_NEW.DEP_TYP_CD

在select语句和group by子句中。

遇到错误似乎无法修复
