DELETE FROM temp_tableSpaceInfo

--定义临时变量在遍历时存储表名称
DECLARE @tablename VARCHAR(255)

--使用游标读取数据库内所有表表名
DECLARE table_list_cursor CURSOR FOR

--打开游标
OPEN table_list_cursor
--读取第一条数据
FETCH NEXT FROM table_list_cursor INTO @tablename

--遍历查询到的表名
WHILE @@FETCH_STATUS = 0
BEGIN
--检查当前表是否为用户表
IF EXISTS (SELECT * FROM sysobjects WHERE id = OBJECT_ID(@tablename) AND OBJECTPROPERTY(id, N‘IsUserTable‘) = 1)
BEGIN
--当前表则读取其信息插入到表格中
EXECUTE sp_executesql N‘INSERT INTO temp_tableSpaceInfo EXEC sp_spaceused @tbname‘, N‘@tbname varchar(255)‘, @tbname = @tablename
END
--读取下一条数据
FETCH NEXT FROM table_list_cursor INTO @tablename
END

--释放游标
CLOSE table_list_cursor
DEALLOCATE table_list_cursor
END
