确定SQL Server数据库大小

Question

SQL Server 2005/2008速成版每个数据库的限制为4 GB。据我所知，数据库引擎仅考虑数据，因此不包括日志文件，未使用的空间和索引大小。

根据SQL Server的限制，获取MDF文件的长度不应给出正确的数据库大小。我的问题是如何获得数据库大小？

Answer 1

注释sp_spaceused

Answer 2

在SQL Management Studio中，在数据库上单击鼠标右键，然后从上下文菜单中选择“属性”。看看“大小”图。

Answer 3

根据SQL2000的帮助，sp_spaceused包含数据和索引。

这个脚本应该做的：

CREATE TABLE #t (name SYSNAME, rows CHAR(11), reserved VARCHAR(18), 
data VARCHAR(18), index_size VARCHAR(18), unused VARCHAR(18)) 

EXEC sp_msforeachtable 'INSERT INTO #t EXEC sp_spaceused ''?''' 
-- SELECT * FROM #t ORDER BY name 
-- SELECT name, CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3)) FROM #t ORDER BY name 
SELECT SUM(CONVERT(INT, SUBSTRING(data, 1, LEN(data)-3))) FROM #t 
DROP TABLE #t 

Answer 4

的sp_helpdb

没有循环需要，不像注释sp_spaceused。

Answer 5

最好的解决方案是可能计算每个数据库文件的大小，使用sys.sysfiles视图，考虑的尺寸8 KB对于每一页的，如下所示：

USE [myDatabase] 
GO 

SELECT 
    [size] * 8 
    , [filename] 
FROM sysfiles 

的〔字段]列表示文件的大小，以页为单位（MSDN Reference to sysfiles）。

你会看到会有至少两个文件（MDF和LDF）：这些文件的总和会给你整个数据库的正确大小......

您可以使用此老式作为一个嗯...

set ANSI_NULLS ON 
set QUOTED_IDENTIFIER ON 
go 

DECLARE @iCount int, @iMax int, @DatabaseName varchar(200), @SQL varchar (8000) 

Select NAME, DBID, crdate, filename, version 
INTO #TEMP 
from MAster..SYSDatabASES 

SELECT @iCount = Count(DBID) FROM #TEMP 

Select @SQL='Create Table ##iFile1 (DBName varchar(200) NULL, Fileid INT, FileGroup int, TotalExtents INT , USedExtents INT , 
Name varchar(100), vFile varchar (300), AllocatedSpace int NUll, UsedSpace int Null, PercentageFree int Null) '+ char(10) 
exec (@SQL) 


Create Table ##iTotals (ServerName varchar(100), DBName varchar(200) NULL, FileType varchar(10),Fileid INT, FileGroup int, TotalExtents INT , USedExtents INT , 
Name varchar(100), vFile varchar (300), AllocatedSpace int NUll, UsedSpace int Null, PercentageFree int Null) 


WHILE @iCount>0 
BEGIN  
    SELECT @iMax =Max(dbid) FROM #TEMP 
    Select @DatabaseName = Name FROM #TEMP where dbid =@iMax 

    SELECT @SQL = 'INSERT INTO ##iFile1(Fileid , FileGroup , TotalExtents , USedExtents , Name , vFile) 
    EXEC (''USE [' + @DatabaseName + '] DBCC showfilestats'') ' + char(10) 

    Print (@SQL) 
    EXEC (@SQL) 


    SELECT @SQL = 'UPDATE ##iFile1 SET DBName ='''+ @DatabaseName +''' WHERE DBName IS NULL' 
    EXEC (@SQL) 


    DELETE FROM #TEMP WHERE dbid =@iMax 
    Select @iCount =@iCount -1 
END 
UPDATE ##iFile1 
SET AllocatedSpace = (TotalExtents * 64.0/1024.0), UsedSpace =(USedExtents * 64.0/1024.0) 

UPDATE ##iFile1 
SET PercentageFree = 100-Convert(float,UsedSpace)/Convert(float,AllocatedSpace )* 100 
WHERE USEDSPACE>0 

CREATE TABLE #logspace (
    DBName varchar(100), 
    LogSize float, 
    PrcntUsed float, 
    status int 
    ) 
INSERT INTO #logspace 
EXEC ('DBCC sqlperf(logspace)') 



INSERT INTO ##iTotals(ServerName, DBName, FileType,Name, vFile,PercentageFree,AllocatedSpace) 
select @@ServerName ,DBNAME, 'Data' as FileType,Name, vFile, PercentageFree , AllocatedSpace 
from ##iFile1 
UNION 
select @@ServerName ,DBNAME, 'Log' as FileType ,DBName,'' as vFile ,PrcntUsed , LogSize 
from #logspace 

Select * from ##iTotals 

select ServerName ,DBNAME, FileType, Sum(AllocatedSpace) as AllocatedSpaceMB 
from ##iTotals 
Group By ServerName ,DBNAME, FileType 
Order By ServerName ,DBNAME, FileType 


select ServerName ,DBNAME, Sum(AllocatedSpace) as AllocatedSpaceMB 
from ##iTotals 
Group By ServerName ,DBNAME 
Order By ServerName ,DBNAME 



drop table ##iFile1 
drop table #logspace 
drop table #TEMP 
drop table ##iTotals 

Answer 7

我总是喜欢直接后打算：

SELECT 
    DB_NAME(dbid) AS DatabaseName, 
    CAST((SUM(size) * 8)/(1024.0 * 1024.0) AS decimal(10, 2)) AS DbSizeGb 
FROM 
    sys.sysaltfiles 
GROUP BY 
    DB_NAME(dbid)
