反正是否在T-SQL中循环表变量？

DECLARE @table1 TABLE ( col1 int )  
INSERT into @table1 SELECT col1 FROM table2

我也使用游标,但游标似乎不如表变量灵活.

DECLARE cursor1 CURSOR  
    FOR SELECT col1 FROM table2  
OPEN cursor1  
FETCH NEXT FROM cursor1

我希望能够以与游标相同的方式使用表变量.这样我就可以在过程的一个部分中对表变量执行一些查询,然后为表变量中的每一行执行一些代码.

任何帮助是极大的赞赏.

我正在使用SQL SERVER 2008 R2.我想获取多个值并同时逐行显示在单个列中,如果值存在,则显示某些值,并且可能是单个列上'12值'的可能性.

例如,下面的屏幕截图显示了除注释之外的相同数据的记录.我想显示为单个记录,但评论应显示ASN及时性,ASN准确性,问题报告这两个值.使用相同的船舶"0096a"逐行显示这三个值.

我的示例查询,

SELECT 
    D30.SPGD30_SHIP_SITE_C AS SHIPSITE,  
    D30.SPGD30_RATING_MONTH_Y AS RATINGMONTH,  
    D30.SPGD30_PRIOR_SCORE_R AS PRIOR, 
    D30.SPGD30_REVISED_SCORE_R AS REVISED,  
    CASE WHEN (CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 ) THEN CONVERT( VARCHAR(8), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X AS DATETIME) , 1) ELSE D30.SPGD30_TRACKED_ADJUSTMENT_X END ADJUSTMENTS,
