SQL STUFF涵数使用 SQL记录接拼字段，方便让SQL行记录转换成列 很方便

--原显示语句（纵）
select  WrgNAME,WrgWXFLG,WrgWO from [DoerERP_E6].dbo.sc_Wrg  where WrgWXFLG=1 AND WrgWO='SC001357' order by WrgNO ;

--SQL字段接拼之后语句（横）
SELECT  WrgWO ,
STUFF((SELECT ',' + WrgNAME  FROM [DoerERP_E6].dbo.sc_Wrg AS e WHERE e.WrgWO = t.WrgWO AND e.WrgWXFLG=1 ORDER BY e.WrgNO FOR XML PATH('')) ,1,1,'') AS '应外发工序/艺'
FROM [DoerERP_E6].dbo.sc_Wrg AS t WHERE t.WrgWXFLG=1 and t.WrgWO='SC001357' GROUP BY t.WrgWO;
