I am not finding the answer that I am looking for. I am sory if there is another post out there some where I just could not find it.
I am trying to find or write a script that is run to enable the transaction log.
I have a PBM that checks the following:
SELECT COUNT(file_id)
FROM sys.database_Files
WHERE type = 1 AND state <> 0
1 = LOG
0 = ONLINE
Instead of following the instructions through the GUI to correct any fails I want to write a script. Seems simple enough but I am unable to determine the correct manner including all pieces I may need.
I figure it is somewhere in the ALTER DATABASE code but I do not see option related to this specifically.
Thanks in advance.

Please explain what you mean above. Transaction logs are not "enabled".

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

I had the same quandry with the wording of the company policy. I believe that enabled just means the same thing as the PBM script.

Basically I think that For Every fail, i.e., db that doesn not have a log file that I need to have a Log file created. I don't think there is an actual STATE_DESC = ONLINE or STATE_DESC = OFFLINE (STATE = 1/0) that pertains to anything but the database. I just started second guessing myself because of this being a Company wide written standard.

so in a nutshell, I want to be able to run a ALTER DATABASE script wth parameters and I think this will be the actual correct response to policy fails.

USE master;

DECLARE@PathNVARCHAR(255),

@FileNameNVARCHAR(128),

@NameNVARCHAR(128),

@SIZENVARCHAR(10),

@MAXSIZENVARCHAR(10),

@FILEGROWTHNVARCHAR(10)

SET @Path=''

SET@Name=''

SET@SIZE=''

SET@MAXSIZE=''

SET@FILEGROWTH=''

SET @FileName= @Path + @Name + '_Log.ldf'

GO

ALTER DATABASE dbTest1

ADD LOG FILE

(

NAME= @Name,

FILENAME= @FileName

SIZE= @SIZE,

MAXSIZE= @MAXSIZE,

FILEGROWTH= @FILEGROWTH

);

GO

I have not been able to locate an example of using parameters in this method however.

Yeah, I'm completely lost as to what the code is trying to code. And if the db is offline, you won't be able to access the view "sys.database_files" within that db anyway.

But you can't have a database without a transaction log. It's impossible, the log file is a critical part of the database. Basically, you will never have an online database without at least one log file.
