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 * from sys.tables


//查询数据库中所有的表名及行数

--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
