代码如下:

declare @id int
declare @type character(2) 
declare @pages int 
declare @dbname sysname
declare @dbsize dec(15,0)
declare @bytesperpage dec(15,0)
declare @pagesperMB dec(15,0)

create table #spt_space( [objid] int null, [rows] int null, [reserved] dec(15) null, [data] dec(15) null, [indexp] dec(15) null, [unused] dec(15) null)

set nocount on

-- Create a cursor to loop through the user tables

declare c_tables cursor forselect id from sysobjects where xtype = 'U'

open c_tables fetch next from c_tables into @id

while @@fetch_status = 0begin /* Code from sp_spaceused */ insert into #spt_space (objid, reserved) select objid = @id, sum(reserved) from sysindexes where indid in (0, 1, 255) and id = @id select @pages = sum(dpages) from sysindexes where indid < 2 and id = @id select @pages = @pages + isnull(sum(used), 0) from sysindexes where indid = 255 and id = @id update #spt_space set data = @pages where objid = @id /* index: sum(used) where indid in (0, 1, 255) - data */ update #spt_space set indexp = (select sum(used) from sysindexes where indid in (0, 1, 255) and id = @id) - data where objid = @id /* unused: sum(reserved) - sum(used) where indid in (0, 1, 255) */ update #spt_space set unused = reserved - ( select sum(used) from sysindexes where indid in (0, 1, 255) and id = @id ) where objid = @id update #spt_space set [rows] = i.[rows] from sysindexes i where i.indid < 2 and i.id = @id and objid = @id fetch next from c_tables into @idend

select TableName = (select left(name,60) from sysobjects where id = objid), [Rows] = convert(char(11), rows), ReservedKB = ltrim(str(reserved * d.low / 1024.,15,0) + ' ' + 'KB'), DataKB = ltrim(str(data * d.low / 1024.,15,0) + ' ' + 'KB'), IndexSizeKB = ltrim(str(indexp * d.low / 1024.,15,0) + ' ' + 'KB'), UnusedKB = ltrim(str(unused * d.low / 1024.,15,0) + ' ' + 'KB')from #spt_space, master.dbo.spt_values dwhere d.number = 1and d.type = 'E'
