下面的SQL语句将得到数据库中所有表的行数:

CREATE TABLE #counts
(
    table_name varchar(255),
    row_count int
)

EXEC sp_MSForEachTable @command1='INSERT #counts (table_name, row_count) SELECT ''?'', COUNT(*) FROM ?'
SELECT table_name, row_count FROM #counts ORDER BY table_name, row_count DESC
DROP TABLE #counts

输出将是一个表列表及其行数。

如果你只想要整个数据库的总行数，追加:

SELECT SUM(row_count) AS total_row_count FROM #counts

将获得整个数据库中总行数的单个值。

我觉得这个看起来比其他的好。

USE  [enter your db name here]
GO

SELECT      SCHEMA_NAME(A.schema_id) + '.' +
        --A.Name, SUM(B.rows) AS 'RowCount'  Use AVG instead of SUM
          A.Name, AVG(B.rows) AS 'RowCount'
FROM        sys.objects A
INNER JOIN sys.partitions B ON A.object_id = B.object_id
WHERE       A.type = 'U'
GROUP BY    A.schema_id, A.Name
GO

这是我最喜欢的SQL 2008解决方案，它将结果放入一个“TEST”临时表，我可以使用它来排序并获得我需要的结果:

SET NOCOUNT ON 
DBCC UPDATEUSAGE(0) 
DROP TABLE #t;
CREATE TABLE #t 
( 
[name] NVARCHAR(128),
[rows] CHAR(11),
reserved VARCHAR(18), 
data VARCHAR(18), 
index_size VARCHAR(18),
unused VARCHAR(18)
) ;
INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?''' 
SELECT * INTO TEST FROM #t;
DROP TABLE #t;
SELECT  name, [rows], reserved, data, index_size, unused FROM TEST \
WHERE ([rows] > 0) AND (name LIKE 'XXX%')

短而甜

sp_MSForEachTable 'DECLARE @t AS VARCHAR(MAX); 
SELECT @t = CAST(COUNT(1) as VARCHAR(MAX)) 
+ CHAR(9) + CHAR(9) + ''?'' FROM ? ; PRINT @t'

输出:

如果您希望通过传递时间和资源来计数(*)您的300万行表。试试Kendal Van Dyke的SQL SERVER Central。

使用sysindexes进行行计数 如果你在使用SQL 2000，你需要像这样使用sysindexes:

-- Shows all user tables and row counts for the current database 
-- Remove OBJECTPROPERTY function call to include system objects 
SELECT o.NAME,
  i.rowcnt 
FROM sysindexes AS i
  INNER JOIN sysobjects AS o ON i.id = o.id 
WHERE i.indid < 2  AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0
ORDER BY o.NAME

如果你正在使用SQL 2005或2008查询sysindexes仍然可以工作，但微软建议sysindexes可能会在SQL Server的未来版本中被删除，因此作为一个良好的实践，你应该使用dmv，如下所示:

-- Shows all user tables and row counts for the current database 
-- Remove is_ms_shipped = 0 check to include system objects 
-- i.index_id < 2 indicates clustered index (1) or hash table (0) 
SELECT o.name,
  ddps.row_count 
FROM sys.indexes AS i
  INNER JOIN sys.objects AS o ON i.OBJECT_ID = o.OBJECT_ID
  INNER JOIN sys.dm_db_partition_stats AS ddps ON i.OBJECT_ID = ddps.OBJECT_ID
  AND i.index_id = ddps.index_id 
WHERE i.index_id < 2  AND o.is_ms_shipped = 0 ORDER BY o.NAME 

在Azure上工作，不需要存储过程。

SELECT t.name       AS table_name
       ,s.row_count AS row_count
FROM   sys.tables t
JOIN   sys.dm_db_partition_stats s
  ON t.OBJECT_ID = s.OBJECT_ID
 AND t.type_desc = 'USER_TABLE'
 AND t.name NOT LIKE '%dss%' --Exclude tables created by SQL Data Sync for Azure.
 AND s.index_id IN (0, 1)
ORDER  BY table_name;

信贷。
