1. simply create a temporary table

drop table #tmp --删除临时表
--创建临时表
create table #tmp (
	ID    VARCHAR(80) not null,
	PNAME VARCHAR(200)
)
INSERT INTO #tmp(ID,PNAME) SELECT ID,CNAME as PNAME from ORG_DEPARTMENT; --把别的表数据存入临时表
SELECT * FROM #tmp;--查询临时表数据


// 创建临时表的另一种方式

drop table #tmpStudent
select *  into #tmpStudent from ES_NOTICE_TARGET
select * from #tmpStudent

2. relatively complex to create a temporary table update field data

BEGIN --开始
drop table #tmp --删除临时表 可以不要 看需求了 不能删一个在建一个 是不是很影响效率
--创建临时表
create table #tmp (
	ID    VARCHAR(80) not null,
	ZCOUNT VARCHAR(200),
	WCOUNT VARCHAR(200),
	YCOUNT VARCHAR(200)
)
--找到别表数据据插入临时表中
INSERT INTO #tmp(ID,ZCOUNT) SELECT NOTICE_ID AS ID,COUNT(DEPT_ID) AS ZCOUNT from ES_NOTICE_TARGET GROUP BY NOTICE_ID;
--更新临时表字段值 按条件更新
 update #tmp  set WCOUNT=(SELECT  COUNT(READS_IS_OK) as WCOUNT  from ES_NOTICE_TARGET  where #tmp.ID=NOTICE_ID AND (READS_IS_OK='0' OR READS_IS_OK IS NULL) GROUP BY NOTICE_ID) 
 where  EXISTS(SELECT NOTICE_ID AS ID from ES_NOTICE_TARGET  GROUP BY NOTICE_ID) 
 update #tmp  set YCOUNT=(SELECT  COUNT(READS_IS_OK) as WCOUNT  from ES_NOTICE_TARGET  where #tmp.ID=NOTICE_ID AND READS_IS_OK='1'  GROUP BY NOTICE_ID) 
 where  EXISTS(SELECT NOTICE_ID AS ID from ES_NOTICE_TARGET  GROUP BY NOTICE_ID) 
SELECT * FROM #tmp; --查询临时表数据
END --结束
GO --go
