Вставить ошибки - подробная информация

Question

Я загружаю некоторые данные во временную таблицу. Затем я использую курсор для циклического перебора временной таблицы, минимизации данных и вставки их в другую таблицу. Идентификатор вновь вставленной записи затем фиксируется в переменной и вставляется в другую таблицу, чтобы можно было искать вновь вставленные данные.

    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

Иногда вставка завершается неудачно, я понятия не имею, почему вставка терпит неудачу. Мне просто интересно, как я могу отобразить более подробную информацию о том, почему вставка действительно не работает?

попробуйте использовать блок catch с несколькими печатными буквами:

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