SQL Server 查询数据库中所有表数据条数

如果是要得到数据库中所有表的条数呢？我们来看几种最常见的方式：

--方法一

代码如下

复制代码

select b.name as tablename ,

c.row_count as datacount

from sys.indexes a ,

sys.objects b ,

sys.dm_db_partition_stats c

where a.[object_id] = b.[object_id]

AND b.[object_id] = c.[object_id]

AND a.index_id = c.index_id

AND a.index_id < 2

AND b.is_ms_shipped = 0

--方法二

代码如下

复制代码

select b.name as tablename ,

a.rowcnt as datacount

from sysindexes a ,

sysobjects b

where a.id = b.id

and a.indid < 2

and objectproperty(b.id, 'IsMSShipped') = 0

--方法三

代码如下

复制代码

if exists ( select *
            from    dbo.sysobjects
            where   id = object_id(N'[dbo].[TableSpace]')
                    and objectproperty(id, N'IsUserTable') = 1 )
    drop table [dbo].[TableSpace]
go
create table TableSpace
    (
      TableName varchar(20) ,
      RowsCount char(11) ,
      Reserved varchar(18) ,
      Data varchar(18) ,
      Index_size varchar(18) ,
      Unused varchar(18)
    )
go
declare @sql varchar(500)
declare @TableName varchar(20)
declare mCursor cursor
for
select name from sysobjects where xtype='U'
open mCursor
fetch NEXT from mCursor into @TableName
while @@fetch_status = 0
    begin
        set @sql = 'insert into TableSpace '
        set @sql = @sql + ' exec sp_spaceused ''' + @TableName + ''' '
        exec (@sql)
        fetch NEXT from mCursor into @TableName
    end
close mCursor
deallocate mCursor
go
--显示结果
select TableName,RowsCount from TableSpace

--建议使用后两种方式，对于SQL SERVER 2005来说，三种方法都好使，如果是其他板本，可以逐一测试一下。

方法四

--==========================================================================
-- 说明：本脚本用于查询当前数据库中所有表格的记录条数
-- 并将结果存入tableinfo表中，不会删除以备用户再做处理与分析
-- 不过，最后请用户删除此表。
--==========================================================================

代码如下

复制代码

if exists (select * from dbo.sysobjects where id = object_id(n[dbo].[tablespace]) and objectproperty(id, nisusertable) = 1)
drop table [dbo].[tablespace]
go

create table tablespace
(
tablename varchar(20),
rowscount char(11),
reserved varchar(18),
data varchar(18),
index_size varchar(18),
unused varchar(18)
)
go

declare @sql varchar(500)
declare @tablename varchar(20)

declare cursor1 cursor
for
select name from sysobjects where xtype=u

open cursor1
fetch next from cursor1 into @tablename

while @@fetch_status = 0
begin
set @sql = insert into tablespace
set @sql = @sql + exec sp_spaceused + @tablename +
exec (@sql)
fetch next from cursor1 into @tablename
end
close cursor1
deallocate cursor1
go

--显示结果
select * from tablespace
--order by tablename
--order by tablename asc --按表名称，用于统计表
--order by rowscount desc --按行数量，用于查看表行数
--order by reserved desc, data desc --按占用空间
--order by index_size desc, reserved desc --按索引空间查看
go

--查看库的使用状况,可以随时执行的。
--exec sp_spaceused
--go
