SQL 2005 - 查询查找大多数行的表格

Question

我搜索了一会儿，但空了......希望有人在这里可以提供帮助。

有没有可以在数据库上运行的查询（SQL Server 2005），它将返回每个表中的行数？

Answer 1

你可以尝试像this：

SELECT 
    [TableName] = so.name, 
    [RowCount] = MAX(si.rows) 
FROM 
    sysobjects so, 
    sysindexes si 
WHERE 
    so.xtype = 'U' 
    AND 
    si.id = OBJECT_ID(so.name) 
GROUP BY 
    so.name 
ORDER BY 
    2 DESC 

Answer 2

这将返回ROW_COUNT，col_count，DATA_SIZE

享受！

Answer 3

Galwegian得到它差不多吧:-)对于SQL Server 2005和起来，我总是使用推荐“SYS。*”系统视图，而不是（即将弃用）的sysobjects和sysindexes表。

SELECT 
    t.NAME AS 'Table Name', 
    SUM(p.[Rows]) as 'Row Count' 
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 
WHERE 
    t.NAME NOT LIKE 'dt%' AND 
    i.OBJECT_ID > 255 AND 
    i.index_id = 1 
GROUP BY 
    t.NAME 
ORDER BY 
    SUM(p.[Rows]) DESC

我不记得在那里我得到了这一点，我敢肯定我没有写它，它肯定是矫枉过正，但它仍然是乐趣。

USE master 
GO 

SET NOCOUNT ON

Answer 5

这里是我的版本，它采用了dm_db_partition_stats DMV：

SELECT object_name(object_id) as table_name, 
    SUM (row_count) AS total_number_of_rows 
FROM sys.dm_db_partition_stats 
WHERE (index_id=0 or index_id=1) 
group by object_name(object_id) 
order by SUM (row_count) desc 

Answer 6

试试这个：

创建表：

create table maxRows (tablename varchar(900) primary key,CountOf int) 

运行此并复制输出：

EXEC sp_msforeachtable 'print ''INSERT INTO maxRows SELECT ''''?'''', COUNT(*) FROM ? WITH (NOLOCK)''' 

运行复制的输出，将其插入到表中的行数为每个表

现在运行此，列出了它们的行的表数：

select countOf,tablename from maxRows order by CountOf DESC

如果在数据库运行，以下返回表行数和索引/总空间使用情况。

declare @tableName varchar(100); 

create table 
    #table 
    (
     tablename sysname, 
     row_count int, 
     reserved varchar(50), 
     data  varchar(50), 
     index_size varchar(50), 
     unused  varchar(50) 
    ); 

create table 
    #table2 
    (
     tableName varchar(100), 
     row_count int, 
     data_size int, 
     index_size int, 
     reserved int, 
     unused  int 
    ); 

declare C_T cursor fast_forward for 
    select  TableName = '[' + s.name + '].[' + t.name + ']' 
    from  sys.tables t 
       inner join sys.schemas s on t.schema_id = s.schema_id 
    where  t.type = 'U' 
    order by s.name, 
       t.name; 

open C_T; 

fetch next from C_T into @tableName; 

while @@FETCH_STATUS = 0 
    begin 
     truncate table #table; 

     insert into #table 
     exec  sp_spaceused @tableName, false; 

     insert into #table2(tableName, row_count, data_size, index_size, reserved, unused) 
     select  @tableName, 
        row_count, 
        convert(int, replace(data, ' KB', '')), 
        convert(int, replace(index_size, ' KB', '')), 
        convert(int, replace(reserved, ' KB', '')), 
        convert(int, replace(unused, ' KB', '')) 
     from  #table; 

     fetch next from C_T into @tableName; 
    end 

close  C_T; 
deallocate C_T; 

select  [Table Name] = tableName, 
      [Rows] = row_count, 
      [Data Size (KB)] = data_size, 
      [Indexes Size (KB)] = index_size, 
      [Reserved Space (KB)] = reserved, 
      [Unused Space (KB)] = unused 
from  #table2 
order by data_size desc; 

drop table  #table; 
drop table  #table2;
