如何获取 SQL SERVER 数据库中所有表的行数

发布于 2024-08-20 14:44:11 字数 151 浏览 7 评论 0原文

我正在寻找一个可用于确定给定数据库的任何表中是否有任何数据(即行数)的 SQL 脚本。

这个想法是在存在任何行(在任何数据库中)的情况下重新体现数据库。

这里所说的数据库是Microsoft SQL Sserver。

有人可以建议一个示例脚本吗?

I am searching for a SQL Script that can be used to determine if there is any data (i.e. row count) in any of the tables of a given database.

The idea is to re-incarnate the database in case there are any rows existing (in any of the database).

The database being spoken of is Microsoft SQL Sserver.

Could someone suggest a sample script?

以下 SQL 将获取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

输出将是表及其行数的列表。

如果您只需要整个数据库的总行数,则附加:

SELECT SUM(row_count) AS total_row_count FROM #counts

将为您提供整个数据库中的总行数的单个值。

The following SQL will get you the row count of all tables in a database:

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

The output will be a list of tables and their row counts.

If you just want the total row count across the whole database, appending:

SELECT SUM(row_count) AS total_row_count FROM #counts

will get you a single value for the total number of rows in the whole database.

如果您想节省计算 (*) 300 万行表所需的时间和资源。请尝试 Kendal Van Dyke 的 SQL SERVER Central。


使用 sysindexes 进行行计数
如果您使用的是 SQL 2000,则需要像这样使用 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

如果您使用的是 SQL 2005 或 2008,查询 sysindexes 仍然有效,但 Microsoft 建议在 SQL Server 的未来版本中可能会删除 sysindexes,以便作为一个好的选择。实践中你应该使用 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 

If you want to by pass the time and resources it takes to count(*) your 3million row tables. Try this per SQL SERVER Central by Kendal Van Dyke.


Row Counts Using sysindexes
If you're using SQL 2000 you'll need to use sysindexes like so:

-- 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

If you're using SQL 2005 or 2008 querying sysindexes will still work but Microsoft advises that sysindexes may be removed in a future version of SQL Server so as a good practice you should use the DMVs instead, like so:

-- 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;

信用

Works on Azure, doesn't require stored procs.

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;

Credit.

这个看起来比我认为的其他更好。

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

This one looks better than the others I think.

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

简短而甜蜜的

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

输出:

在此处输入图像描述

更新:
如果数据库非常大,此查询可能会占用大量资源。 (根据评论)

Short and sweet

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

Output:

Update:
This query may be resource-intensive if the database is very large. (As per comment)

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。它位于标准报告中 - 它是按表列出的光盘使用情况。

从编程角度来说,有一个很好的解决方案:
http://www.sqlservercentral.com/articles/T-SQL/67624/

SQL Server 2005 or later gives quite a nice report showing table sizes - including row counts etc. It's in Standard Reports - and it is Disc Usage by Table.

Programmatically, there's a nice solution at:

不要使用SELECT COUNT(*) FROM TABLENAME,因为这是一个资源密集型操作。应使用 SQL Server 动态管理视图系统目录获取某个表中所有表的行计数信息数据库。

Don't use SELECT COUNT(*) FROM TABLENAME, since that is a resource intensive operation. One should use SQL Server Dynamic Management Views or System Catalogs to get the row count information for all tables in a database.

这里有一个动态 SQL 方法,它还为您提供了架构:

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,可以轻松地将其扩展为在实例中的所有数据库上运行(连接到 sys.databases )。

Here's a dynamic SQL approach that also gives you the schema as well:

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)

If needed, it would be trivial to extend this to run over all databases in the instance (join to sys.databases).

我会对 Frederik 的解决方案做一些小小的改变。我将使用 sp_spaceused 系统存储过程,其中还包括数据和索引大小。


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 = 'sp_spaceused ' + @tablename 

    exec sp_executesql @stmt

    fetch next from c_tables into @tablename 

end 

close c_tables 
deallocate c_tables 

I would make a minor change to Frederik's solution. I would use the sp_spaceused system stored procedure which will also include data and index sizes.


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 = 'sp_spaceused ' + @tablename 

    exec sp_executesql @stmt

    fetch next from c_tables into @tablename 

end 

close c_tables 
deallocate c_tables

从 information_schema.tables 视图中选择所有行,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

select all rows from the information_schema.tables view, and issue a count(*) statement for each entry that has been returned from that view.

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

这是我最喜欢的 SQL 2008 解决方案,它将结果放入“TEST”临时表中,我可以用它来排序并获取我需要的结果:

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%')

This is my favorite solution for SQL 2008 , which puts the results into a "TEST" temp table that I can use to sort and get the results that I need :

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%')
