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 

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%')

从information_schema中选择所有行。表视图，并为从该视图返回的每个条目发出count(*)语句。

declare c_tables cursor fast_forward for
select table_name from information_schema.tables

open c_tables
declare @tablename varchar(255)
declare @stmt nvarchar(2000)
declare @rowcount int
fetch next from c_tables into @tablename

while @@fetch_status = 0
begin

    select @stmt = 'select @rowcount = count(*) from ' + @tablename

    exec sp_executesql @stmt, N'@rowcount int output', @rowcount=@rowcount OUTPUT

    print N'table: ' + @tablename + ' has ' + convert(nvarchar(1000),@rowcount) + ' rows'

    fetch next from c_tables into @tablename

end

close c_tables
deallocate c_tables

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。

SQL Server 2005或更高版本提供了一个相当不错的报告，显示表大小-包括行数等。这是在标准报告-它是光盘使用表。

在编程上，有一个很好的解决方案: http://www.sqlservercentral.com/articles/T-SQL/67624/

下面是一个动态SQL方法，它也提供了模式:

DECLARE @sql nvarchar(MAX)

SELECT
    @sql = COALESCE(@sql + ' UNION ALL ', '') +
        'SELECT
            ''' + s.name + ''' AS ''Schema'',
            ''' + t.name + ''' AS ''Table'',
            COUNT(*) AS Count
            FROM ' + QUOTENAME(s.name) + '.' + QUOTENAME(t.name)
    FROM sys.schemas s
    INNER JOIN sys.tables t ON t.schema_id = s.schema_id
    ORDER BY
        s.name,
        t.name

EXEC(@sql)

如果需要，将其扩展为在实例中运行所有数据库(连接到sys.databases)是很简单的。
