Connecting In Read-only Mode
Feb 18, 2008
I posted this as a reply to another thread but then noticed it was marked as 'Answered' so i figured I'll create a new one.
This is a known issue (i guess) that you need to have write access to the database your connecting to but I actually want to know how to connect to a database with read only permissions. This should not be that rare of a case where you only want to read something without writting to it. I have a system where users can connect to other databases and "import" data from there but if the user doesn't have write access or the file is read only I get an exception.
Any idea how I can connect in read-only mode?
Thanks!

Hi,
About a month ago, a couple of our databases started up in read-only mode for some reason. I am the new DBA on the job, and the error logs from a month ago are not present.
I was wondering if anyone has had a problem where a SQLServer 7.0 database did this to them? We restart our DBs each day using scripts, so it is odd that this happens only intermittently (no one has seen a pattern at this point).
Any information would be muc appreciated!
Thanks,
Joe

Hi,Version Info: SQLSERVER 2000 SP3I am trying to understand how SQL Server works with SERIALIZABLE read.I am fairly new to SQL Server, having mainly worked with Informix.We are getting lock timeout error in our application. Our lock timeoutis set to 20 seconds. I am trying to investigate why locks are held forsuch a long time in the first place.I believe SQLServer tries to put keylocks as much as possible forensuring serializibility. For e.g.SELECT column_bfrom table_awhere column_c between 1000 and 1100what if column_c has no index. Does it switch over the data row.And what if a table has no index. Will it go for table lock, as ituse to do in earlier versions.TIA.--email id is bogus

Hi,
I have made setup of my program,
I need to attach a db to the server. To do this:
- Copy mdf and ldf files into default data folder of instance of sqlexpress
- run scrip from custom action in the installer that:
a. attach the db
b. create login
c. create user for login in db
There is a problem...I run script slq file by sqlcmd and launch it from a c# process.
The rusult is that the db was attacched but in only read mode, and the point c not work.
If I execute manually the same script sql with sqlcmd in dos window, it work without problem in all point: a,b and c
What are the reason of this?
I think that start process in c# not work correctly....this is the code:
process = new Process();
process.StartInfo.FileName = "sqlcmd.exe";
process.StartInfo.Arguments = commandLine;
process.Start();
process.WaitForExit();
help me, plese!
thanks in advance

we are about to start a logshipping with the secondary server in read only mode.
I just wanted to know the disadvantages of using a read only on the secondary server.
I mean whether the transactional logs will be restored periodically or it won't be restored till users are connected on the secondary server.

Hi,Does anyone know how I can connect to an MSDE db using VB with aread-only file? The file will be on a CD, and is actually just archiveddata off a SQL server. I would like to package my app on a CD alongwith the data file and allow users to pop in the CD and run the app,assuming they already have MSDE running. Any help?Thanks,Jason

We have reports in SharePoint integrated mode which are really slow when compared to native mode. I have been asked to research and give info on what exactly causes the delays.
Any articles which give me information as to what happens when a report is run from SharePoint server and where does it log.

Hello,everyone!!
There is a query which when executed in the grid mode(ctrl+d) takes approx 0.02 seconds(about 21,000
rows) But when I execute in the text mode, it takes about 0.40 seconds!!
Why is this difference?
Also, when the records from this table are read from a VB application, they are equally slow (as in the text mode!)
Why is it so slow on the text mode & relatively faster in the grid mode?
Has anyone got any idea on ‘Firehose’ style cursor ?(which may speed up access of data in the VB application)
Rgds,
Adie

Hi,
Currently, our Report Builder is running on Local Intranet mode. I'm investigating what the security implications are in changing it to Internet mode. However, I've not been able to find any documentation on this.
Does anyone know of any documentation that addresses this issue or have experience that they can share with changing Report Builder security zone from Intranet mode to Internet mode?
Thanks very much.

Hi folks,
I have a SQL 2005 OTC. CTP version running on Windows 2003 server.
I would like to find out how the SQL server option changed to Windows Authentication mode from Mixed mode over the weekend. From the SQL log, I don't see when it changed. I would like to see Date/Time and client IP. If I can see User ID (windows) that would be great. Where I can find these info in SQL server?
Thank you in advance...

I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1
Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
thanks

i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?

OK, I'm using VS2003 and I'm having trouble. The page works perfectly when I created it with WebMatrix but I want to learn more about creating code behind pages and this page doesn't work. I think it has some things to do with Query builder but I can't seem to get change outside "please register". I have the table populated and it is not coming back with "login successful" or "password wrong" when I've entered correct information. Enclosed is what I've done in VS2003. Can you see where my error is? Any help would be greatly appreciated.
Thanks again.

I know that PerSeat is each individual computer that accesses SQL Server
and PerServer is the number of concurrent connections to the server.
