最近第一次使用sql表變量，感覺挺好用，案例如下：

　　declare @aaa table(Com_SiteGroupID uniqueidentifier) --定義表變量

　　---往表變量裏寫數據

insert into @aaa select Com_SiteGroupID from Com_SiteGroup where Com_StructureID [email protected]
union all
select a.Com_SiteBasicID from Com_SiteBasic a inner join Com_SiteGroup b on

--讀取表變量的數據

insert into #temp select c.ObjectText,count(*) as CountNum from Sip_HiddenDisposalInfo a
inner join Sc_InspectionContent b
on a.Sc_InspectionContentID=b.Sc_InspectionContentId inner join Sc_InspectionItem c
on b.Sc_InspectionItemId=c.Sc_InspectionItemId where c.CheckLevel=2
