SQL多个逗号分开的字段值 取对应的数据名称信息

字段值

 

函数实现：

ALTER function [dbo].[GetName](@strs NVARCHAR(500))
RETURNS NVARCHAR(4000) 
as
begin
 set @strs=','+@strs+','
 DECLARE @str1 NVARCHAR(4000)
 DECLARE @str2 NVARCHAR(4000)
 set @str2=''
 declare SyncOrderCursor cursor for 
 select b.Name from dbo.ShopStore as a 
 inner join dbo.Shop as b  on a.StoreGid=b.Gid 
  where @strs like  '%,'+cast(a.Gid as nvarchar(4000))+',%'
 open SyncOrderCursor  
 fetch next from SyncOrderCursor into @str1
 while @@FETCH_STATUS=0
 begin
     set @str2=@str2+'|'+@str1
  fetch next from SyncOrderCursor into @str1
 end
 close SyncOrderCursor
 deallocate SyncOrderCursor
 
return @str2
End

---另一种实现方式
--select A.Gid,stuff((
--    select '|'+B.Name  from Shop B
--    where charindex(','+CAST(B.Gid as varchar(8000))+',',','+ CAST (B.Gid as varchar(8000))+',')>0
--    order by B.Gid
--    for xml path('')
--    ),1,1,'') as name 
--from ShopStore A

调用函数实现：

 [dbo].GetName(Gids) AS ShopName
