Determine SQL Server Database Size

Question

SQL Server 2005/2008 Express edition has the limitation of 4 GB per database. As far as I known the database engine considers data only, thus excluding log files, unused spa

Answer 1

You could use this old fashioned one as well...

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
