今天要统计一下数据库里所有表当前的最大id，一个一个查太麻烦了，就写了一个存储过程，方便今后继续使用。
CREATE PROCEDURE [dbo].[get_tableid] AS
CREATE TABLE #tablespaceinfo --创建结果存储表
(nameinfo varchar(50) ,
max_idinfo int )
DECLARE @tablename varchar(255) --表名称
DECLARE @max_idinfo int
DECLARE Info_cursor CURSOR FOR
SELECT o.name
FROM dbo.sysobjects o WHERE OBJECTPROPERTY(o.id, N‘IsTable‘) = 1
and o.name not like N‘#%%‘ ORDER BY o.name
OPEN Info_cursor
FETCH NEXT FROM Info_cursor
INTO @tablename
WHILE @@FETCH_STATUS = 0
BEGIN
if exists (select * from dbo.sysobjects where id = object_id(@tablename) and OBJECTPROPERTY(id, N‘IsUserTable‘) = 1)
BEGIN
SELECT @max_idinfo=IDENT_CURRENT(@tablename)
INSERT #tablespaceinfo (nameinfo,max_idinfo)
VALUES (@tablename,@max_idinfo)
END
FETCH NEXT FROM Info_cursor
INTO @tablename
END
CLOSE Info_cursor
DEALLOCATE Info_cursor
SELECT * FROM #tablespaceinfo ORDER BY nameinfo DESC
