如何列出数据库中每个表的行数。相当于

select count(*) from table1
select count(*) from table2
...
select count(*) from tableN

我会张贴一个解决方案,但其他方法是受欢迎的

您可以复制,过去和执行这段代码,以获得所有表记录计数到一个表。注意:代码带有注释

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

我已经测试了这段代码,它在SQL Server 2014上运行良好。

其他回答

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

输出:

select T.object_id, T.name, I.indid, I.rows 
  from Sys.tables T 
  left join Sys.sysindexes I 
    on (I.id = T.object_id and (indid =1 or indid =0 ))
 where T.type='U'

这里indid=1表示群集索引,而indid=0表示堆索引

        SELECT ( Schema_name(A.schema_id) + '.' + A.NAME ) AS TableName,
 Sum(B.rows)AS RecordCount 
    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 ;

我认为最短、最快、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
