SELECT STUFF((SELECT ','+ PageSize FROM TB WHERE FOR XML PATH('')),1,1,'') AS PageSize

------解决方案--------------------
SQL code
declare @s nvarchar(2000)
select @s=isnull(@s+',','')+rtrim(PageSize) from Tab
select @s as PageSize

------解决方案--------------------
SQL code
SELECT STUFF((SELECT ','+ PageSize FROM TB FOR XML PATH('')),1,1,'') AS PageSize

------解决方案--------------------
SQL code
use Tempdb
go
--> --> 
 
if not object_id(N'Tempdb..#') is null
    drop table #
Go
Create table #([PageSize] int)
Insert #
select 9 union all
select 1 union all
select 8

/*如何将一列中所有的值一行显示
数据源
  a
  b
  c
  d
  e
结果
a,b,c,d,e
*/

create table tb(col varchar(20))
insert tb values ('a')
insert tb values ('b')
insert tb values ('c')
insert tb values ('d')
insert tb values ('e')
go

--方法一
declare @sql varchar(1000)
set @sql = ''
select @sql = @sql + t.col + ',' from (select col from tb) as t
set @sql='select result = ''' + left(@sql , len(@sql) - 1) + ''''
exec(@sql)
/*
result     
---------- 
a,b,c,d,e,
*/

--方法二
declare @output varchar(8000)
select @output = coalesce(@output + ',' , '') + col from tb
print @output
/*
a,b,c,d,e
*/

drop table tb
