只有一個表達式可以在選擇列表中指定當子查詢未與EXISTS引入

Question

下面是一個查詢

select IssueNo, KendraCode, IssueTime, DateOfIssue, P_MotaBags, P_MotaWeight, P_PatlaBags, P_PatlaWeight, P_SarnaBags, P_SarnaWeight, NewBags,OldBags, TransporterName, TruckNumber, DriverName, TruckOwner,SocietyCode 
, 
(SELECT PaddyMotaW, PaddyPatlaW, PaddySarnaW, BagsMota, BagsPatla, BagsSarna,PC_ID, sangrahankendraid, SocietyCode,DM_ID FROM ReceiveFromSociety WHERE DM_ID=S.IssueNo) 
from IssueToSangrahanKendra_Soc S 
where KendraCode='4403' order by SocietyCode 

問題出在哪裏

Answer 1

你不能在那樣的子查詢中選擇多個字段，只有1個字段將被允許。

另外，對代碼進行格式化將使得將來更容易閱讀。

請嘗試以下

select IssueNo, 
     KendraCode, 
     IssueTime, 
     DateOfIssue, 
     P_MotaBags, 
     P_MotaWeight, 
     P_PatlaBags, 
     P_PatlaWeight, 
     P_SarnaBags, 
     P_SarnaWeight, 
     NewBags, 
     OldBags, 
     TransporterName, 
     TruckNumber, 
     DriverName, 
     TruckOwner, 
     SocietyCode, 
     rfs.* 
from IssueToSangrahanKendra_Soc S LEFT JOIN 
     ( SELECT PaddyMotaW, 
        PaddyPatlaW, 
        PaddySarnaW, 
        BagsMota, 
        BagsPatla, 
        BagsSarna, 
        PC_ID, 
        sangrahankendraid, 
        SocietyCode, 
        DM_ID 
      FROM ReceiveFromSociety 
     ) rfs ON rfs.DM_ID =S.IssueNo 
where KendraCode='4403' 
order by SocietyCode
