如何查看SQL2000数据库中所有表的数据量大小

Posted 2023-03-19

软件运行非常慢，我想看看是那些数据表的数据量大，应该如何查询，

比如我要看到每一个表占了多大的空间，有办法吗？

直接在查询分析器运行即可：
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 for
select id
from sysobjects
where xtype = 'U'

open c_tables

fetch next from c_tables
into @id

while @@fetch_status = 0
begin

/* 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 @id
end

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 d
where d.number = 1
and d.type = 'E'
order by reserved desc
drop table #spt_space
close c_tables
deallocate c_tables 参考技术A 每张表都有一个数据库文件dbf，看一下就行了，不过我建议 select count（'*'） from table,一下，对于数据行增加较快的表可考虑重新规划一下。 参考技术B 目前没有办法，不过我身边有高手，我帮你问问。

sql 查看所有表的数据量

select schema_name(t.schema_id) as [Schema], t.name as TableName,i.rows as [RowCount] 
from sys.tables as t, sysindexes as i 
where t.object_id = i.id and i.indid <=1
