Question

我已多次检查过这个问题。列数匹配，但仍然会出现以下错误：

Cursorfetch：INTO列表中声明的变量数必须为与所选列的匹配。

我知道这个问题已被多次询问过，但我仍然陷入困境。任何帮助将不胜感激。感谢。

DECLARE @prev_s_Case CHAR(4)= null,@prev_startDate DATETIME= null,@prev_endDate DATETIME= null, @prev_ukey INT= null, @cur_s_Case CHAR(4), @cur_startDate DATETIME, @cur_endDate DATETIME, @cur_ukey INT, @result varchar(500);

DECLARE THE_CURSOR CURSOR FOR
SELECT  s_Case, startDate, endDate, ukey FROM   #TEMP
ORDER BY s_Case

BEGIN
OPEN THE_CURSOR;

FETCH NEXT FROM THE_CURSOR 
INTO @cur_s_Case, @cur_startDate, @cur_endDate, @cur_ukey

WHILE (@@FETCH_STATUS=0)
    SELECT s_Case, startDate, endDate, ukey  
    FROM #TEMP

    IF (    (@prev_s_Case = @cur_s_Case))
    BEGIN
        IF ((@cur_startDate BETWEEN @prev_startDate AND @prev_endDate) AND (@cur_endDate >= @prev_endDate))
        BEGIN
            SET @result = CASE WHEN @result = '' THEN str(@prev_ukey)
                            ELSE @result + ','+ str(@prev_ukey) END
        END
        ELSE IF ((@cur_startDate BETWEEN @prev_startDate AND @prev_endDate)
                AND (@cur_endDate < @prev_endDate))
        BEGIN
            SET @result = CASE WHEN @result = '' THEN str(@cur_ukey)
                            ELSE @result + ','+ str(@cur_ukey) END
        END
    END

    SET @prev_s_Case= @cur_s_Case;
    SET @prev_startDate = @cur_startDate;
    SET @prev_endDate = @cur_endDate;
    SET @prev_ukey = @cur_ukey;

    FETCH NEXT FROM THE_CURSOR 
    INTO @cur_s_Case,@cur_startDate,@cur_endDate,@cur_ukey

    print @result
CLOSE THE_CURSOR;

DEALLOCATE THE_CURSOR;
END

Cursorfetch：变量的数量必须与所选列的数量匹配
