sqlserver查询数据的所有表名和行数

原文:sqlserver查询数据的所有表名和行数

//查询所有表明select name from sysobjects where xtype=‘u‘

select * from sys.tables

//查询数据库中所有的表名及行数

SELECT  a.name AS [TABLE NAME] ,
        b.rows AS [RECORD COUNT]
FROM    sysobjects AS a
        INNER JOIN sysindexes AS b ON a.id = b.id
WHERE   ( a.type = ‘u‘ )
        AND ( b.indid IN ( 0, 1 ) )
ORDER BY a.name ,
        b.rows DESC

//查询所有的标明及空间占用量\行数

--创建临时表
CREATE   TABLE ##RowCount
    (
      [TABLE NAME] VARCHAR(500) ,
      [RECORD COUNT] INT
    )
--执行存储过程
EXEC sp_msforeachtable ‘insert   into   ##RowCount   ([TABLE NAME],[RECORD COUNT])   select   ‘‘?‘‘   tableName,   count(*)   dataCount from   ?‘   

--查询结果
SELECT  *
FROM    ##RowCount
ORDER BY [TABLE NAME]  

DROP TABLE ##RowCount 

--统计一个数据库中所有表记录的数量
-- 最近公司的数据库发现有表的数据被弄掉了，有些数据表记录为0，于是想找出此数据库中到底有哪些数据表的记录都为0以缩小分析范围，可使用如下的SQL Statement: 

CREATE   TABLE #tmptb
    (
      tbname sysname ,
      tbrows INT ,
      tbREserved VARCHAR(10) ,
      tbData VARCHAR(10) ,
      tbIndexSize VARCHAR(10) ,
      tbUnUsed VARCHAR(10)
    ) 

INSERT  INTO #tmptb
        EXEC sp_MSForEachTable ‘EXEC   sp_spaceused   ‘‘?‘‘‘ 

SELECT  *
FROM    #tmptb
 --列出所有表的情况 

SELECT  tbrows ,
        tbname
FROM    #tmptb
WHERE   tbrows = 0 --列出记录数据为0的表
ORDER BY tbname

DROP TABLE #tmptb

--其中
--tbname     表名
--tbrows     记录数
--tbREserved     保留空间
--tbData     使用空间
--tbIndexSize     索引使用空间
--tbUnUsed   未用空间
