常用脚本--查看数据库中各表的行数和大小

--======================================
--查看各表的行数
--is_ms_shipped=0代表用户创建的表
--(I.indid=1 OR I.indid=0)代表聚簇索引和堆表
SELECT T.name AS TableName,
I.rows AS RowsCount,
(I.dpages*8/1024) AS DataSpaceMB,
((I.used-I.dpages)*8/1024) AS IndexSpaceMB,
(I.used*8/1024) AS TotalSpaceMB
FROM sys.sysindexes I
INNER JOIN sys.tables T
ON I.id=T.object_id
and (I.indid=1 OR I.indid=0)
AND T.is_ms_shipped=0
 
 
--======================================
--使用EXEC sys.sp_spaceused @tbname来获取表的大小和行数
IF(OBJECT_ID('tempdb.dbo.#tablespaceinfo') IS NOT NULL)
BEGIN
DROP TABLE #tablespaceinfo
PRINT 'DROP TABLE #tablespaceinfo'
END
CREATE TABLE #tablespaceinfo
(
   nameinfo VARCHAR(50),
   rowsinfo INT,
   reserved VARCHAR(20),
   datainfo VARCHAR(20),
   index_size VARCHAR(20),
   unused VARCHAR(20)
);
DECLARE @tablename VARCHAR(255); --表名称
DECLARE @cmdsql VARCHAR(500);
DECLARE Info_cursor CURSOR FOR
SELECT T.name
FROM sys.tables T
WHERE is_ms_shipped=0;
OPEN Info_cursor;
FETCH NEXT FROM Info_cursor
INTO @tablename;
WHILE (@@FETCH_STATUS = 0)
BEGIN
execute sp_executesql
N'INSERT INTO #tablespaceinfo EXEC sys.sp_spaceused @tbname',
N'@tbname varchar(255)',
@tbname = @tablename
FETCH NEXT FROM Info_cursor
INTO @tablename
END
CLOSE Info_cursor
DEALLOCATE Info_cursor
SELECT * FROM #tablespaceinfo
 --======================================
--使用sys.dm_db_partition_stats查看各表的行数
 --======================================
--使用sys.dm_db_index_physical_stats查看各表的行数
--dm_db_index_physical_stats会导致锁表，请谨慎使用。
 
 SELECT * FROM sys.dm_db_index_physical_stats
(DB_ID(N'DB1'), OBJECT_ID(N'dbo.TB22'), NULL, NULL , 'DETAILED');
 
 

 

另外一种方式，首先生成脚本

--======================================
--使用EXEC sys.sp_spaceused 来获取表的大小和行数
IF(OBJECT_ID('tempdb.dbo.#tablespaceinfo') IS NOT NULL)
BEGIN
DROP TABLE #tablespaceinfo
PRINT 'DROP TABLE #tablespaceinfo'
END
CREATE TABLE #tablespaceinfo
(
   nameinfo VARCHAR(50),
   rowsinfo INT,
   reserved VARCHAR(20),
   datainfo VARCHAR(20),
   index_size VARCHAR(20),
   unused VARCHAR(20)
);
GO

SELECT 
N'INSERT INTO #tablespaceinfo 
EXEC sys.sp_spaceused ''['+SCHEMA_NAME(T.schema_id)+'].['+T.name+']'''
FROM sys.tables T
