SQL Server 得到数据库中所有表的名称及数据条数

提到单个表的数据条数，大家都会想到 select count(*) from tablename

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
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


--方法二
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 
--方法三        
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 
        
--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。
