Question

我尝试定义以下SQL Server嵌套游标语句：我循环日历并将它们从cut_calendar迁移到sd_calendar。每个日历也有日历日。它们也会被每个日历移动所移动。

 DECLARE @id NUMERIC(20)
    DECLARE @sdCalendarId NUMERIC(20)
    DECLARE @calendarTypId NUMERIC(5)
    DECLARE @name NVARCHAR(35)
    DECLARE @description NVARCHAR(255)
    DECLARE @ptyId NUMERIC(20)
    DECLARE @lockCode NVARCHAR(20)
    DECLARE @dataOwnerId NUMERIC(20)
    DECLARE @cntId NUMERIC(20)
    DECLARE @nonBusinessDaysMonday CHAR(1)
    DECLARE @nonBusinessDaysTuesday CHAR(1)
    DECLARE @nonBusinessDaysWednesday CHAR(1)
    DECLARE @nonBusinessDaysThursday CHAR(1)
    DECLARE @nonBusinessDaysFriday CHAR(1)
    DECLARE @nonBusinessDaysSaturday CHAR(1)
    DECLARE @nonBusinessDaysSunday CHAR(1)
    DECLARE @ccyId NUMERIC(20)
    DECLARE @code NVARCHAR(30)
    DECLARE @version NUMERIC(10)
    DECLARE @seal VARCHAR(255)
    DECLARE @lstUpdTs DATETIME
    DECLARE @day_id NUMERIC(20)
    DECLARE @day_calDate DATETIME
    DECLARE @day_lockCode NVARCHAR(20)
    DECLARE @day_calComment NVARCHAR(255)
    DECLARE @day_dataOwnerId NUMERIC(20)
    DECLARE @day_calendarId NUMERIC(20)
    DECLARE @day_calRecurring CHAR(1)
    DECLARE @day_version NUMERIC(10)
    DECLARE @day_seal VARCHAR(255)
    DECLARE @day_lstUpdTs DATETIME
    DECLARE @day_sdCalendarDaysId NUMERIC(20)
    DECLARE @sdCodeId NUMERIC(20)


    DECLARE cursorCutoffCalendar CURSOR FOR
      SELECT ID, NAME, CALENDAR_TYP_ID,DESCRIPTION,PTY_ID,LOCK_CODE,DATA_OWNER_ID,CNT_ID,NON_BUSINESS_DAYS_MONDAY,NON_BUSINESS_DAYS_TUESDAY,NON_BUSINESS_DAYS_WEDNESDAY,NON_BUSINESS_DAYS_THURSDAY,NON_BUSINESS_DAYS_FRIDAY,NON_BUSINESS_DAYS_SATURDAY,NON_BUSINESS_DAYS_SUNDAY,CCY_ID,CODE,VERSION,SEAL,LST_UPD_TS

    WHILE @@FETCH_STATUS = 0
    BEGIN
        SELECT @sdCalendarId = COALESCE(MAX(ID),1) FROM SD_CALENDAR
        SET @sdCalendarId = @sdCalendarId + 1

        UPDATE CUT_CALENDAR_DAY
        SET CALENDAR_ID = @sdCalendarId
        WHERE CALENDAR_ID = @id

        SELECT @sdCodeId = ID FROM SD_CALENDAR WHERE CODE = @code
        IF @sdCodeId > 0
            SET @code = CONCAT(@code, '_co')
        ELSE

        INSERT INTO SD_CALENDAR (ID, NAME, CALENDAR_ROLE_ID,DESCRIPTION,USE_IN_CUTOFF,PTY_ID,LOCK_CODE,DATA_OWNER_ID,CNT_ID,NON_BUSINESS_DAYS_MONDAY,NON_BUSINESS_DAYS_TUESDAY,NON_BUSINESS_DAYS_WEDNESDAY,NON_BUSINESS_DAYS_THURSDAY,NON_BUSINESS_DAYS_FRIDAY,NON_BUSINESS_DAYS_SATURDAY,NON_BUSINESS_DAYS_SUNDAY,CCY_ID,CODE,VERSION,SEAL,LST_UPD_TS)
        VALUES(@sdCalendarId, @name, @calendarTypId,@description,1,@ptyId,@lockCode,@dataOwnerId,@cntId,@nonBusinessDaysMonday,@nonBusinessDaysTuesday,@nonBusinessDaysWednesday,@nonBusinessDaysThursday,@nonBusinessDaysFriday,@nonBusinessDaysSaturday,@nonBusinessDaysSunday,@ccyId,@code,@version,@seal,@lstUpdTs)

        DECLARE cursorCutoffCalendarDays CURSOR FOR
          SELECT ID, CAL_DATE, LOCK_CODE,CAL_COMMENT,DATA_OWNER_ID,CALENDAR_ID,CAL_RECURRING,VERSION,SEAL,LST_UPD_TS
          FROM CUT_CALENDAR_DAY
          WHERE ID != 1

        OPEN cursorCutoffCalendarDays
        FETCH NEXT FROM cursorCutoffCalendarDays INTO @day_id, @day_calDate, @day_lockCode, @day_calComment, @day_dataOwnerId, @day_calendarId, @day_calRecurring, @day_version, @day_seal, @day_lstUpdTs
        WHILE @@FETCH_STATUS = 0
        BEGIN
            SELECT @day_sdCalendarDaysId = COALESCE(MAX(ID),1) FROM SD_CALENDAR_DAY
            SET @day_sdCalendarDaysId = @day_sdCalendarDaysId + 1

            INSERT INTO SD_CALENDAR_DAY (ID, CAL_DATE, LOCK_CODE,CAL_COMMENT,DATA_OWNER_ID,CALENDAR_ID,CAL_RECURRING,VERSION,SEAL,LST_UPD_TS)
            VALUES(@day_sdCalendarDaysId, @day_calDate, @day_lockCode, @day_calComment, @day_dataOwnerId, @day_calendarId, @day_calRecurring, @day_version, @day_seal, @day_lstUpdTs)


        FETCH NEXT FROM cursorCutoffCalendarDays INTO @day_sdCalendarDaysId, @day_calDate, @day_lockCode, @day_calComment, @day_dataOwnerId, @day_calendarId, @day_calRecurring, @day_version, @day_seal, @day_lstUpdTs

        END
        CLOSE cursorCutoffCalendarDays
        DEALLOCATE cursorCutoffCalendarDays
        GO

        DELETE FROM CUT_CALENDAR
        WHERE ID = @id

    FETCH NEXT FROM cursorCutoffCalendar INTO @sdCalendarId, @name, @calendarTypId, @description, @ptyId, @lockCode, @dataOwnerId, @cntId, @nonBusinessDaysMonday, @nonBusinessDaysTuesday, @nonBusinessDaysWednesday, @nonBusinessDaysThursday, @nonBusinessDaysFriday, @nonBusinessDaysSaturday, @nonBusinessDaysSunday, @ccyId, @code, @version, @seal, @lstUpdTs

    END
    CLOSE cursorCutoffCalendar
    DEALLOCATE cursorCutoffCalendar
    GO

现在，当我运行此操作时，出现以下错误：

SQLServerException：

cursorCutoffCalendarDays是我的语句的内部游标。

Answer 1

尝试从以下位置删除GO：

    CLOSE cursorCutoffCalendarDays
    DEALLOCATE cursorCutoffCalendarDays
    GO

我同意你从GarethD那里得到的评论，我曾经写过像这样的游标，但后来我问如何在没有光标的情况下做到这一点并得到一个很好的解释

Answer 2

块引用

从此行中删除Go，然后尝试

 CLOSE cursorCutoffCalendarDays
 DEALLOCATE cursorCutoffCalendarDays
