如何列出数据库中每个表的行数。

的一些等价物 
select count(*) from table1
select count(*) from table2
...
select count(*) from tableN

我会发布一个解决方案，但欢迎其他方法

如果您正在使用SQL Server 2005及更高版本，您也可以使用它：

SELECT 
    t.NAME AS TableName,
    i.name as indexName,
    p.[Rows],
    sum(a.total_pages) as TotalPages, 
    sum(a.used_pages) as UsedPages, 
    sum(a.data_pages) as DataPages,
    (sum(a.total_pages) * 8) / 1024 as TotalSpaceMB, 
    (sum(a.used_pages) * 8) / 1024 as UsedSpaceMB, 
    (sum(a.data_pages) * 8) / 1024 as DataSpaceMB
FROM 
    sys.tables t
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%' AND
    i.OBJECT_ID > 255 AND   
    i.index_id <= 1
GROUP BY 
    t.NAME, i.object_id, i.index_id, i.name, p.[Rows]
ORDER BY 
    object_name(i.object_id)

在我看来，它比sp_msforeachtable输出更容易处理。

我在http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=21021找到的片段帮助了我：

select t.name TableName, i.rows Records
from sysobjects t, sysindexes i
where t.xtype = 'U' and i.id = t.id and i.indid in (0,1)
order by TableName;

要在SQL Management Studio中获取该信息，请右键单击数据库，然后选择Reports - ＆gt;标准报告 - ＆gt;表格中的磁盘使用情况。

答案 3 :(得分：8)

SELECT 
    T.NAME AS 'TABLE NAME',

As seen here,这将返回正确的计数，其中使用元数据表的方法仅返回估计值。

    CREATE PROCEDURE ListTableRowCounts 
    AS 
    BEGIN 
        SET NOCOUNT ON 

        CREATE TABLE #TableCounts
        ( 
            TableName VARCHAR(500), 
            CountOf INT 
        ) 

        INSERT #TableCounts
            EXEC sp_msForEachTable 
                'SELECT PARSENAME(''?'', 1), 
                COUNT(*) FROM ? WITH (NOLOCK)' 

        SELECT TableName , CountOf 
            FROM #TableCounts
            ORDER BY TableName 

        DROP TABLE #TableCounts
    END
    GO

在SQL Refreence中查找所有表的行数的最快方法（http://www.codeproject.com/Tips/811017/Fastest-way-to-find-row-count-of-all-tables-in-SQL）

SELECT T.name AS [TABLE NAME], I.rows AS [ROWCOUNT] 
    FROM   sys.tables AS T 
       INNER JOIN sys.sysindexes AS I ON T.object_id = I.id 
       AND I.indid < 2 
ORDER  BY I.rows DESC

幸运的是，SQL Server管理工作室为您提供了如何执行此操作的提示。 这样做，

  1. 启动SQL Server跟踪并打开您正在执行的活动（过滤器 如果您并不孤单，请使用您的登录ID并设置应用程序名称 到Microsoft SQL Server Management Studio），暂停跟踪并丢弃迄今为止记录的所有结果;
  2. 然后，右键单击表格并从弹出菜单中选择属性;
  3. 再次开始追踪;
  4. 现在在SQL Server Management Studio中选择左侧的存储属性项;

    5. 暂停跟踪并查看microsoft生成的TSQL。

    在可能的最后一个查询中，您将看到以exec sp_executesql N'SELECT

    开头的语句

    当您将执行的代码复制到visual studio时，您会注意到此代码会生成microsoft工程师用于填充属性窗口的所有数据。

    当您对该查询进行适度修改时，您将得到如下内容：

    SELECT
SCHEMA_NAME(tbl.schema_id)+'.'+tbl.name as [table], --> something I added
p.partition_number AS [PartitionNumber],
prv.value AS [RightBoundaryValue],
 fg.name AS [FileGroupName],
CAST(pf.boundary_value_on_right AS int) AS [RangeType],
CAST(p.rows AS float) AS [RowCount],
p.data_compression AS [DataCompression]
FROM sys.tables AS tbl
INNER JOIN sys.indexes AS idx ON idx.object_id = tbl.object_id and idx.index_id < 2
INNER JOIN sys.partitions AS p ON p.object_id=CAST(tbl.object_id AS int) AND p.index_id=idx.index_id
LEFT OUTER JOIN sys.destination_data_spaces AS dds ON dds.partition_scheme_id = idx.data_space_id and dds.destination_id = p.partition_number
LEFT OUTER JOIN sys.partition_schemes AS ps ON ps.data_space_id = idx.data_space_id
LEFT OUTER JOIN sys.partition_range_values AS prv ON prv.boundary_id = p.partition_number and prv.function_id = ps.function_id
LEFT OUTER JOIN sys.filegroups AS fg ON fg.data_space_id = dds.data_space_id or fg.data_space_id = idx.data_space_id
LEFT OUTER JOIN sys.partition_functions AS pf ON  pf.function_id = prv.function_id

    现在查询并不完美，您可以更新它以满足您可能遇到的其他问题，重点是，您可以通过执行您感兴趣的数据，利用microsoft的知识来解决您遇到的大多数问题并使用探查器跟踪生成的TSQL。

    我有点想认为MS工程师知道SQL服务器是如何工作的，它会产生TSQL，它可以使用您正在使用的SSMS版本处理的所有项目，所以它在很多种类的版本上都很好用prerviouse ，现在和未来。

    请记住，不要只是复制，尝试理解它，否则你可能会得到错误的解决方案。

在Azure SQL上，我接受的答案对我没有用，这里one确实如此，它超级快，完全符合我的要求：

select t.name, s.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%'
    and s.index_id = 1
order by s.row_count desc

首先想到的是使用sp_msForEachTable 

exec sp_msforeachtable 'select count(*) from ?'

虽然没有列出表名，但可以扩展到

exec sp_msforeachtable 'select parsename(''?'', 1),  count(*) from ?'

这里的问题是，如果数据库有超过100个表，您将收到以下错误消息：

  

查询已超过最大值   可以的结果集数量   显示在结果网格中。只要   前100个结果集是   显示在网格中。

所以我最终使用表变量来存储结果

declare @stats table (n sysname, c int)
insert into @stats
    exec sp_msforeachtable 'select parsename(''?'', 1),  count(*) from ?'
select 
    * 
from @stats
order by c desc

答案 10 :(得分：1)

此方法使用字符串连接来动态生成包含所有表及其计数的语句，如原始问题中给出的示例：

          SELECT COUNT(*) AS Count,'[dbo].[tbl1]' AS TableName FROM [dbo].[tbl1]
UNION ALL SELECT COUNT(*) AS Count,'[dbo].[tbl2]' AS TableName FROM [dbo].[tbl2]
UNION ALL SELECT...

最后，使用EXEC：

执行此操作 
DECLARE @cmd VARCHAR(MAX)=STUFF(
                    (
                        SELECT 'UNION ALL SELECT COUNT(*) AS Count,''' 
                              + QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME) 
                              + ''' AS TableName FROM ' + QUOTENAME(t.TABLE_SCHEMA) + '.' + QUOTENAME(t.TABLE_NAME)
                        FROM INFORMATION_SCHEMA.TABLES AS t
                        WHERE TABLE_TYPE='BASE TABLE'
                        FOR XML PATH('')
                    ),1,10,'');
EXEC(@cmd);

我想分享对我有用的东西 

SELECT
      QUOTENAME(SCHEMA_NAME(sOBJ.schema_id)) + '.' + QUOTENAME(sOBJ.name) AS [TableName]
      , SUM(sdmvPTNS.row_count) AS [RowCount]
FROM
      sys.objects AS sOBJ
      INNER JOIN sys.dm_db_partition_stats AS sdmvPTNS
            ON sOBJ.object_id = sdmvPTNS.object_id
WHERE 
      sOBJ.type = 'U'
      AND sOBJ.is_ms_shipped = 0x0
      AND sdmvPTNS.index_id < 2
GROUP BY
      sOBJ.schema_id
      , sOBJ.name
ORDER BY [TableName]
GO

我认为最短，最快和最简单的方法是：

SELECT
    object_name(object_id) AS [Table],
    SUM(row_count) AS [Count]
FROM
    sys.dm_db_partition_stats
WHERE
    --object_schema_name(object_id) = 'dbo' AND 
    index_id < 2
GROUP BY
    object_id

你可以试试这个：

        OBJECT_NAME(ps.object_id) AS [tablename],
        row_count AS [rows]
FROM sys.dm_db_partition_stats ps
WHERE OBJECT_SCHEMA_NAME(ps.object_Id) <> 'sys' AND ps.index_id < 2
ORDER BY 
        OBJECT_SCHEMA_NAME(ps.object_Id),
        OBJECT_NAME(ps.object_id)

此sql脚本提供了所选数据库中每个表的模式，表名和行数：

SELECT SCHEMA_NAME(schema_id) AS [SchemaName],
[Tables].name AS [TableName],
SUM([Partitions].[rows]) AS [TotalRowCount]
FROM sys.tables AS [Tables]
JOIN sys.partitions AS [Partitions]
ON [Tables].[object_id] = [Partitions].[object_id]
AND [Partitions].index_id IN ( 0, 1 )
-- WHERE [Tables].name = N'name of the table'
GROUP BY SCHEMA_NAME(schema_id), [Tables].name
order by [TotalRowCount] desc

DECLARE @src NVARCHAR(MAX), @sql NVARCHAR(MAX);

SELECT @sql = N'', @src = N' UNION ALL

  INNER JOIN [$d].sys.tables AS t ON s.[schema_id] = t.[schema_id]
  INNER JOIN [$d].sys.sysindexes AS ind ON t.[object_id] = ind.[id]
  where ind.indid < 2';

SELECT @sql = @sql + REPLACE(@src, '$d', name)
  FROM sys.databases
  WHERE database_id > 4
    AND [state] = 0
    AND HAS_DBACCESS(name) = 1;

您可以复制，粘贴并执行这段代码，以将所有表记录计数都放入表中。注意：代码中有注释说明

create procedure RowCountsPro
as
begin
--drop the table if exist on each exicution
IF OBJECT_ID (N'dbo.RowCounts', N'U') IS NOT NULL 
DROP TABLE dbo.RowCounts;
-- creating new table
CREATE TABLE RowCounts 
( [TableName]            VARCHAR(150)
, [RowCount]               INT
, [Reserved]                 NVARCHAR(50)
, [Data]                        NVARCHAR(50)
, [Index_Size]               NVARCHAR(50)
, [UnUsed]                   NVARCHAR(50))
--inserting all records
INSERT INTO RowCounts([TableName], [RowCount],[Reserved],[Data],[Index_Size],[UnUsed])
--  "sp_MSforeachtable" System Procedure, 'sp_spaceused "?"' param to get records and resources used
EXEC sp_MSforeachtable 'sp_spaceused "?"' 
-- selecting data and returning a table of data
SELECT [TableName], [RowCount],[Reserved],[Data],[Index_Size],[UnUsed]
FROM RowCounts
ORDER BY [TableName]
end

Shnugo 的答案是唯一一个在 Azure 中使用 Externa Tables 的答案。 (1) Azure SQL 根本不支持 sp_MSforeachtable 并且 (2) 外部表的 sys.partitions 中的行始终为 0。

select T.object_id, T.name, I.indid, I.rows 
  from Sys.tables T 
  left join Sys.sysindexes I

 where T.type='U'

如果您使用MySQL＆gt; 4.x，您可以使用：

select TABLE_NAME, TABLE_ROWS from information_schema.TABLES where TABLE_SCHEMA="test";

请记住，对于某些存储引擎，TABLE_ROWS是近似值。
