【解決方法】現在、変数にはカーソルが割り当てられていません。

[ad_1]

こんにちは、みんな、

カーソルを使用しようとしていますが、エラーが表示されます。変数には、割り当てられているにもかかわらず、現在カーソルが割り当てられていません。ご協力をよろしくお願いいたします。前もって感謝します。

私が試したこと:

SQL

<pre>DECLARE @firstday1 Date = null,
	@Lastday1 Date = null,
	@RequestType1 nvarchar = null,
	@EmployeeIdRequest1 int = null


SELECT @firstday1 = FORMAT(PeriodFrom,'yyyy-MM-dd') , @Lastday1 = FORMAT(PeriodTo,'yyyy-MM-dd') ,@RequestType1 = TRIM(RequestType),@EmployeeIdRequest1 = EmployeeID  FROM MST_TBL_Approvalrequests WHERE Autoid = 	@ApprovalReqID;


 DECLARE @Enumerator1 CURSOR 
		SET @Enumerator1 = CURSOR  FAST_FORWARD FOR
				 with dates_CTE1 (date) as (
						select @firstday1 
						Union ALL
						select DATEADD(day, 1, date)
						from dates_CTE1
						where date < @Lastday1
						)	
				select  date  FROM dates_CTE1
				OPTION (maxrecursion 365);
		OPEN @Enumerator1
		DECLARE @LoopDate1 date
	
		WHILE (1=1)
				BEGIN
					FETCH NEXT FROM @Enumerator1 into @LoopDate1	
						IF (@@FETCH_STATUS <> 0) break

	   BEGIN
	   if exists(SELECT AutoId from PPMS_TBL_AttendanceMaster where FORMAT(date,'yyyy-MM-dd')=@LoopDate1 and EmployeeID = @EmployeeIdRequest1 )            
       BEGIN 
        UPDATE PPA SET

		and (date BETWEEN PeriodFrom  AND PeriodTo) and MSTA.EmployeeID = @EmployeeIdRequest1   AND  RequestTypeID in (1,2,3,4,5,6,7,8,9,10)

		END
		ELSE
		BEGIN
	    INSERT INTO [PPMS_TBL_AttendanceMaster](EmployeeID, Name, [Date], AttendanceStatus,PresentStatus)

        END

        end
        CLOSE @Enumerator1
		DEALLOCATE @Enumerator1
