MsSQL 2019-01-04

<div class="codetitle"><a style="CURSOR: pointer" data="92275" class="copybut" id="copybut92275" onclick="doCopy('code92275')"> 代码如下:

<div class="codebody" id="code92275">
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','部件人员不足;')
insert into tb values('55','跨间场地积压;图纸问题较多;')
insert into tb values('56','300','AAAA;')
insert into tb values('56','BBBB;')
insert into tb values('56','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,''))
end

调用
<div class="codetitle"><a style="CURSOR: pointer" data="83989" class="copybut" id="copybut83989" onclick="doCopy('code83989')"> 代码如下:

<div class="codebody" id="code83989">
select distinct standards,amount,variation,statuss,Reason = dbo.test('55') from tb where standards=55
select distinct standards,Reason = dbo.test('56') from tb where standards=56
