Union All
create View
as
select col from t1 union all select col from t2
怎么加一个自增列呢?
请注意sql2000 这里是。
------解决方案--------------------
CREATE VIEW 没有加自增列的。
SELECT ID=IDENTITY(INT,1,1),. INTO #T
------解决方案--------------------
union后的东东放入临时表用吧!
- SQL code
select *,id = identity(int,1,1) into #tbfrom( select .. from tb1 union all select .. from tb2)t
------解决方案--------------------
CREATE VIEW
AS
SELECT * FROM
(SELECT col ,
(SELECT COUNT(*) FROM
(SELECT col FROM t1 UNION ALL SELECT col FROM t2) AS A2
WHERE A2.col<A1.col) AS RANK
FROM (SELECT col FROM t1 UNION ALL SELECT col FROM t2) AS A1) AS B
ORDER BY RANK
------解决方案--------------------
在2000环境下验证通过.
- SQL code
CREATE VIEW ASSELECT * FROM (SELECT col , (SELECT COUNT(*) FROM (SELECT col FROM t1 UNION ALL SELECT col FROM t2) AS A2 WHERE A2.col<A1.col) AS RANK FROM (SELECT col FROM t1 UNION ALL SELECT col FROM t2) AS A1) AS BORDER BY RANK
