Check SQL Server data space allocation_PHP tutorial

Today, a customer reported that the database file space is growing too fast and needs to analyze the database table storage space allocation. I temporarily wrote the following process and
shared it with everyone.
/********************************
Function: Get the spatial distribution of the table ycsoft 2005-07-13
**********************************/
if not exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[tablespaceinfo]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
create table tablespaceinfo --Create result storage table
(nameinfo varchar(50),
rowsinfo int, reserved varchar(20),
datainfo varchar(20),
index_size varchar(20) ,
unused varchar(20) )
delete from tablespaceinfo --clear the data table
declare @tablename varchar(255) --table name
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
--knowsky.com database information
sp_spaceused @updateusage = 'TRUE'
--Table information
select *
from tablespaceinfo
order by cast(left(ltrim(rtrim(reserved))) , len(ltrim(rtrim( reserved)))-2) as int) desc
