Sql function 多行中的列合并为一行一列的方法，需要的朋友可以参考下。 CREATE TABLE tb(standards varchar(50), amount varchar(50), variation varchar(50),statuss varchar(50),Reason varchar(50)) insert into tb values('55','279','4','物量积压','加工人员设备不足;T排制作进度较慢;') insert into tb values('55','279','4','物量积压','部件人员不足;') insert into tb values('55','279','4','物量积压','跨间场地积压;图纸问题较多;') insert into tb values('56','300','4','物量积压','AAAA;') insert into tb values('56','300','4','物量积压','BBBB;') insert into tb values('56','300','4','物量积压','CCCC;') create function test(@standards varchar(100)) returns varchar(8000) as begin declare @re varchar(500) set @re = '' select @re = @re+','+Reason from tb where @standards=standards return (stuff(@re,1,1,'')) end 调用 select distinct standards,amount,variation,statuss,Reason = dbo.test('55') from tb where standards=55 select distinct standards,amount,variation,statuss,Reason = dbo.test('56') from tb where standards=56 |
