[MSSQL]获取SQL Server数据库里表的占用容量大小

创建了一个名为get_tableinfo的存储过程，用于获取SQL Server数据库中用户表的占用容量信息。过程首先检查并创建结果存储表tablespaceinfo，然后通过游标Info_cursor遍历所有用户表，使用sp_spaceused动态SQL插入数据。执行存储过程后，按预留空间大小降序展示所有表的容量详情。

CREATE PROCEDURE get_tableinfo AS
if not exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[tablespaceinfo]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) 
create table  tablespaceinfo                         --创建结果存储表 
              (nameinfo varchar(50) ,  
               rowsinfo int , reserved varchar(20) ,  
               datainfo varchar(20)  ,  
               index_size varchar(20) ,  
               unused varchar(20) )

delete from tablespaceinfo --清空数据表
declare @tablename varchar(255)  --表名称
declare @cmdsql varchar(500)
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) 
  execute sp_executesql  
         N'insert into tablespaceinfo  exec sp_spaceused @tbname', 
          N'@tbname varchar(255)', 
          @tbname = @tablename
  FETCH NEXT FROM Info_cursor  
  INTO @tablename  
END
CLOSE Info_cursor 
DEALLOCATE Info_cursor 
GO

 
执行存储过程 
exec get_tableinfo
查询运行该存储过程后得到的结果 
select * 
from tablespaceinfo  
order by cast(left(ltrim(rtrim(reserved)) , len(ltrim(rtrim(reserved)))-2) as int) desc
