Hello All,
I am hoping you can help. I need to find out if it is possible to read the location of the sql logs from the database. I am aware that it is normally saved at a default location, but it also might be that the user who installed it configured it to be different. I would want to write an application that would do a query to the database and get the path to the log files;
Kind Regards.Wink

Try this (note, credit to Gert Drapers - it was his script initially)

declare @dir nvarchar(4000)

exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE',N'Software\Microsoft\MSSQLServer\MSSQLServer',N'SQLArg1', @dir output, 'no_output'

if @dir is null
begin
exec master.dbo.xp_instance_regread N'HKEY_LOCAL_MACHINE',N'Software\Microsoft\MSSQLServer\Setup',N'SQLDataRoot', @dir output, 'no_output'
select @dir = @dir + N'\LOG'
end

select @dir

here you go try this, reports database name, logical filename and log file locations for all databases on an instance


select a.name, b.name as 'Logical filename', b.filename from sys.sysdatabases a
inner join sys.sysaltfiles b
on a.dbid = b.dbid where fileid = 2

This script will give you what you want with SQL Server 7.0, 2000, or 2005. It gets the file information for every database on a server, and gives various levels of analysis of file space usage.

I think you are looking for this:
SELECT SERVERPROPERTY('ErrorLogFileName')

(If you mean the server logs and not the database logs)

I need the query to determine the mdf file location of a database.

just change fileid to 1 instead of 2 as below


select a.name, b.name as 'Logical filename', b.filename from sys.sysdatabases a
inner join sys.sysaltfiles b
on a.dbid = b.dbid where fileid = 1
