set quoted_identifier off
declare @sql nvarchar(1000)
--set @mobile= 142423254
set @sql= 'select * from OPENQUERY(mysqllinkserver, ' 'select uid from user1 where mobile_num= ' ' ' ' '+@mobile+ ' ' ' ' ' ' ') ' ----这里这么多符号是什么意思啊?
exec sp_executesql @sql
set quoted_identifier on
[解决办法]
set @sql= 'select @uid=uid from OPENQUERY(mysqllinkserver, ' 'select uid from user1 where mobile_num= ' ' ' ' '+@mobile+ ' ' ' ' ' ' ') '
