插入失敗 - 詳細信息

Question

我正在將一些數據加載到臨時表中。然後我使用一個遊標循環遍歷臨時表，將數據小型化，然後將其插入到另一個表中。新插入的記錄的身份然後被捕獲到一個變量中，並插入到另一個表中以允許查找新插入的數據。

DECLARE c1 CURSOR READ_ONLY 
FOR 
SELECT NEWClientIndex, ClientGroup, ClientAccount, SKAccount, SKDesc, SKBase, SKBranch, ClientType, SKStatus, GFCID, GFPID, Account_Open_Date, Account_Update, 
         SKType 
FROM @ClientsAccounts 

OPEN c1 


FETCH NEXT FROM c1 
INTO @NEWClientIndex, @ClientGroup, @ClientAccount, @SKAccount, @SKDesc, 
    @SKBase, @SKBranch, @ClientType, @SKStatus, @GFCID, @GFPID, @Account_Open_Date, 
    @Account_Update, @SKType 

WHILE @@FETCH_STATUS = 0 
    BEGIN 
PRINT 'Processing Account' 

     Print 'Inserting Account Information' 
     -- We now need to loop through the data inserting account information 
     -- and maintaining the Account link table 
     -- Each itteration of the cursor should result in one insert 
     -- as each account should be linked to one client 

     INSERT INTO CitiClientsAccounts (SKBranch, SKAccount, SKName, SKBase, SyncStatus, 
      GFCID, GFPID, SyncInput, SyncUpdate, Deleted, Branch_Account, LastUpdatedBy, AccountTypeID) 
      VALUES(convert(varchar(2), @SKBranch), convert(varchar(12), @SKAccount), convert(varchar(255),@SKDesc), 
      convert(varchar(16),@SKBase), convert(varchar(50),@SKStatus), convert(varchar(10),@GFCID), convert(varchar(10),@GFPID), 
      @Account_Open_Date, @Account_Update, 0, convert(varchar(16),@ClientAccount), 'Admin', convert(int, @SKType)) 


      Declare @NEWID int 
      Select @NEWID = SCOPE_IDENTITY() 
      IF @NEWID is NULL 
       BEGIN 
        Print 'Account Insert Failed' 
       END 
      ELSE 
       BEGIN 

        --Match up account to the Client ID 
        Declare @ClientID int 
        Select @ClientID = LocalPrimaryKey 
         from dbo.CitiClients_LIBRARY 
        Where AccessPimaryKey = @NEWClientIndex 

        Print 'Updating Library' 
        Insert into dbo.ClientAccountLink 
         (AccountID, ClientID, LastUpdatedBy) 
        Values 
         (@NEWID, @ClientID, 'Admin') 

      END 
      Print 'End Insert Account Information' 
     -- Move to Next Row 
     FETCH NEXT FROM c1 
     INTO @NEWClientIndex, @ClientGroup, @ClientAccount, @SKAccount, @SKDesc, 
      @SKBase, @SKBranch, @ClientType, @SKStatus, @GFCID, @GFPID, @Account_Open_Date, 
      @Account_Update, @SKType 
    END 
CLOSE c1 
DEALLOCATE c1 

有時插入失敗，我不知道爲什麼插入失敗。我只是想知道如何顯示更詳細的信息爲什麼插入實際上失敗？

嘗試使用catch塊有更多的一些版畫：

DECLARE @ErrorMessage nvarchar(400), @ErrorNumber int, @ErrorSeverity int, @ErrorState int, @ErrorLine int,@CatchMessage varchar(500)
