SQL 2005 TempDB In 6.5 Compatibility Mode
Feb 1, 2008
On my current contract we have a SQL 2005 box with a user database and the tempdb database in 6.5 compatibility mode. I would like to remove the user database and change the tempdbs compatibility mode. When you try and use EM just about everything fails with errors about collation or syntax. From what I have found it could be related to the tempdb being in 6.5 compatibility mode but either way I would like to remove this old unused DB.
My question is after I remove the user DB and reset the tempdb compatibility mode what will or could break? I haven't been able to find much on what would change or what to look out for after the change is made. Has anyone else done this? If so what issues did you face.
Thanks
Doug

Hi,
We are planning to upgrage our SS 2000 databases(couple of hundreds) to SS 2005.
To minimise the potential work arounds, it is agreed to have complex databases, continue running on compatibility mode 80. What are the potential impact of having database on mode 80(apart from not being able to use new feature)on SS2005?
Fruther how we can we import SS 2000 DTSs to SS 2005 SSIS in an cluster environment?
Thanks,
Sajish

Hi All
I€™m having a problem setting up maintenance plans on one of our SQL 2005 servers but first here€™s a bit of back ground.
The server is a Virtual machine running win2k3R2 SP2 server std and SQL 2k5, A supplier arrived to install and app on the server when discovering there app didn€™t work with 2k5 they seem to have set the 2 dbs on the server into 2k compatibility mode and set the entire SQL install to think its a 2000 install. (I€™m not sure how this is done all I can see is the wrong version number in management studio) The problem this is giving me it that the folder in management studio for Database Maintenance Plans is no longer under the management folder instead it under a sub folder called Legacy (which is how management studio seems to deal with all registered 2000 instances) and as such a can no longer right click and create new database maintenance plans is there any way around this or will I have to setup my backup job manually?
Ohh and have the supplier shot at dawn
Thanks All
Jon

Can you run SQL Server 2005 in SQL Server 2000 compatibility mode and still use it with Reporting Services 2005?

I am in the process of migrating from Sql Server 2000 to 2005. Part of my plan is to move some database's to 2005, but use the 2000 compatibility mode for the short term. My issue is this, our DR boxes are still on SQL Server 2000, would I still be able to use our log shipping processes? Or would I be better off in starting with migrating the DR boxes to 2005 first?
Thanks in advance.

We have some users who are nervous about our upgrading to SQL Server 7.0 even though we will use 6.5 compatibility mode initially while we work through 7.0 upgrade issues in the applications.
Has anyone had bad experiences with the 6.5 compatibility mode feature? Just how good is it?
Cheers
Matt

I have a Sql Server 2005 instance that was upgraded from 2000. The compatibility mode of master is still set to 80. Can I change this to 90?

I currently use MSDE and now I need to upgrade because we moved to 2005. The problem for me is teh compatibility mode. I need to change it to 80 (2000).
I also need to do it via command line because we have a base command line install for users.
We use it to attach databases and view information.
Is there a way to install SQL Express with a default mode of 80 (SQL 2000).
THanks

I have been migrating Databases from a SQL Server 7.0 Instance to a 2000 Instance. Basically the method I use is as follows:
a)Create a new Database on the Destination Server (same name as the Source) When I create the new Database on my destination server, the compatibility mode is '80' and the source is always '70'
b) do a 'revlogin' on the Source Server and use the output from that query to recreate the logins on the destination server
c) make sure that the default DB for the newly creates logins are correct and change them if necessary
d) Backup the DB on the Source Server and Restore it to the Destination Server.
e) Check login permissions and fix any orphaned users - usually I don't find any that need to be fixed, but I always check.
I've read BOL on Changing the compatibility mode on the Database... but I'm still unsure when I would have to do this and why???????????????? SHOULD I be changing the compatiblity mode from 80 to 70 when migrating Databases from 7.0 to 2000???? Any advice on moving DBs in this manner would be appreciated.

I have a 2005 database sitting on a 2012 server, we're looking to change its compatibility mode from 90 to 110 so we can avail of what 2012 offers.I did a migration project a couple years ago for SQL Server 2000 databases changing to 2008 R2 and we ran into loads of problems where we left most databases in compatibility mode 80 as these were application databases that the owners couldn't stand over in terms of deprecated code / features no longer in use in 2008 R2.
From what I can see with changing from 90 to 110, there doesn't seem to be as many issues but I just want to double check if there's a way to confirm this. I know upgrade advisor is a handy tool but will it pick up database specific issues as opposed to database server compatibility issues? URLs...I know UA won't cover all the bases but it would look good when attached to the report I'm submitting recommending the change.

I'm running SQL Server 7.0. I have a DB running with 6.5 compatibility mode.
Do INSERT, UPDATE or DELETE queries use row level locking in this DB ?
(I know if I set the db compatibility mode to 7.0 row level locking will be enabled)
Thanks in advance for your help.

We recently upgraded out SQL version from SQL2008R2 to SQL2014. As such, the compatibility mode changed to SQL2104 (120).
We have several queries that used to run fine that now take forever to bring back results. There are no errors (which surprised me). They just take way too long now. PLus they seem to be causing high I/O and CPU.
If I change the compt level back to SQL2008 - these queries run fine.
QUERY with SQL2008 compt level - finished in 2 minutes.
QUERY with SQL2014 compt level - finishes in 3 hours 22 minutes.
same exact query - same server - only thing changed was compatibility level.
WHat do I look for in the queries that could be causing this? (they look fine but obviously I'm missing something here)..

Hi,
I've been scouring the forums and the web for anything that would substantiate an argument for database application developers to keep developing in SQL 8.0 when we have migrated to SQL 2005.
I read somewhere that compatibility 8.0 mode is an intern stepping stone for migrating from 8 to 9, but it seems 2005 will handle and run compat 8.0 databases just fine.
So am finding it really diffucult to substantiate my argument against running 2005 with all databases in compatibility 8 mode indefinitly.
Any suggestions or links that could help me with this.
Joe

We upgraded QA and production to sql server 2012 last year ( in place) leaving the user databases at sql 2005 ( 90 ). A few months ago the QA user databases were set to sql 2012 compatibility mode. Management is worried about upgrading production and wants to know if we can quickly roll back.
I want to confirm that we can roll back using the same command, and if dbcc freeproccache can be used to avoid having to update all statistics.
ALTER DATABASE <mydatabase> SET COMPATIBILITY_LEVEL = 110
ALTER DATABASE <mydatabase> SET COMPATIBILITY_LEVEL = 90
This works fine in QA on my own test user database. No errors.

I am relatively new to SQL Server so excuse my ignorance.
I have noticed in many of my SQL Server 2005 instances that the tempdb database is very often reporting the log mode as waiting active_transaction or waiting checkpoint.
Is this of concern, how can I determine the cause of these waits and how can they be reduced or eliminated ?

Something strange is happening to our SQL Server DB (2000). Thetempdb transaction log file continues to grow (quite slowly) for noapparent reason. We have it in simple mode, and I have tried a manualcheckpoint command and manual shrink (of the log file only). Thereare no unusual SQL's (large or small) going on. A "heavy hitter" wouldmake it grow fast, not 10 MB every 30 minutes or so. This server hasbeen in production for over a year with no similar issues to this.Anyone encounter a similar situation? This started (as far as we cantell) sometime yesterday. It is growing about 200 MB a day, and is upto 600 MB now, with all but 8 MB "used". For now we added space, butof course that is not a long term solution. The two "data" files(each had a 200 MB initial allocation) have never gone much above 100MB each used (they are each about 100 MB now and have been that wayfor several days, but have shrank and grown). There are about 30small to medium sized "regular" databases on this instance.Any help would be appreciated, especially if there is a way we can fixthis without bouncing the engine (I know, wishful thinking...). The OSis Win 2000, SP3. SQL Server is at 2000, SP 3a.THANKS IN ADVANCE!

Don't want to find out later that you can't run a sql 2005 express database on a sql 2005 server.

I am a newbie developing a web site. My local machine has sql 2005 standard edition on it. The host that I am trying to use only has sql 2005 64 bit version.
would I be able to do the use the same database between the two ( i.e. once my site is running at host, would I be able to download the database on my local machine, make changes to my site and then upload again on the hose without any glitches?). In addition, how about sql express doing the same with sql 2005 64 bit.
Thanks a lot for taking time to read the post.

I am attempting to install SQL Express 2005 SP2 on a Windows 2000 Server computer. Can someone tell me if this version of SQL is compatible with this operating system? I am getting a warning that my system does not meet the minimum hardware requirements when attempting the install.
I have 512bm of memory (minimum requirement is 192), a PIII/866mhz processor (minimum requirement is a PIII/600mhz) and plenty od disk space. So is it the operating system that is causing this warning?
I also have the Windows Installer 3.1 as well as the Dot Net Framework 2.0 installed.
Any ideas?
Thanks for your help - Steve

Are there any known issues with using RDO with SQL Server 2005?
My company is in the process of updating our SQL Server 7 database to
SQL Server 2005. Most of our applications are several years old and
written using RDO to access the database. I have since started the
daunting task of updating all the applications to ADO, but it's only
about a quarter of the way done. We need to update the database ASAP,
but we cannot wait until all the applications have been updated to ADO.
While testing the applications (written in VB6) against the new SQL
Server 2005 database, I have come across a problem with the RDO queries
not returning the correct data. The query returns 4 records. In the
SQL7, it properly shows 4 for RowCount and 4 records are present in the
recordset (as seen by looping through the recordset using rs.MoveNext).
In SQL2005, it properly shows 4 for RowCount, but looping through the
recordset shows that the recordset only contains 1 record. The problem
seems to be linked to a Left Join in the Query. (see below) Table1 has
a column that has a RecID for Table2. In the case where the Table2RecID
column in Table1 is 0, the row is just not added to the recordset even
though it increments the RowCount.
Code:
SELECT * FROM Table1 As T1
LEFT JOIN Table2 As T2 On T1.Table2RecID = T2.RecID
I converted the query to ADO and it ran fine with no problems. The issue has something to do with SQL Server 2005 and RDO.

In a new environment where we have 2005 servers and loads of databases that are running in compatibility mode with 2000 (80)
Are there any queries we can run on that can tell me what compatibility level each db is?
Looked on the web for ages apart from here but only info for changing the compatibility level - sp_dbcmptlevel – but queies only seem to be for changing it not and not reporting on it.
But I obviously do not want to do that for a production environment.
I want to do a mini report as to what db’s are still (I think all) 2000 mode and then suggest upgrades – I can go into the properties of each one but I know there must be an easier way – finding a load of admin queries that require cross apply and for that I need 2005 (90) compatibility….or is that only for the master db?

I have a hosted solution where the web host provider tells me I'm running on a 2005 platform, but when I check the DB options, it shows compatibility level 80. The provider tells me I'm not losing any performance by running in the lower compatibility mode. Is this truly the case? What else am I losing out on in terms of features or capabilities?

Hi There,
We have been using SQL 2005 in our dev enviroment for a few weeks, and I have just completed migrating our production server to a 64bit instance of SQL 2005 standard.
I have 3 publications, 1 snapshot, and 2 transactional. All go to SQL 2000 databases.
Our dev enviroment is in compatibility level 90, and our application is working fine. My concern is, will changing the production compatibility level from 80 to 90 affect / break replication to SQL 2000 Servers?
Thank you.

Hi All,
We have upgraded our database from SQL 2000 to SQL 2005 keeping the compatibility level 80.
Now the question is -
Would microsoft support compatibility level 80 in SQL Server 2005 even after the extended support date for SQL Server 2000?
OR
If Microsoft dropped the support for SQL 2000, then would Microsoft support compatibility level 80 in SQL Server 2005?
Thanks

We have the following trace flags present in startup in SQL server 2000:

Need to understand if these should be required in SQL Server 2005 + SP2 version. I have run the upgrade advisor tool which indcates that the behaviour of some flags has changed and some other TFs are no longer applicable. Hence, I want to know about the above mentioned TFs.

In one PC we have installed MsOffice 2003 and recently installed SQL Server 2005 personal edition, but now we have a problem because there is a compatibility problem between them. We need some upgrade for Access to avoid it, but can't find it.
Can We fix this problem, maintainning Access 2003 and SQL Server 2005 personal edition and maintainning the support for our clients?
Notice that our clients can't upgrade, in the short time.
