SQL 2012 :: Changing Compatibility Mode From 90 To 110
Jul 20, 2015
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.
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)..
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.
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?
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).
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.
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.
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.
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?
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?
I have a problem where I have a software application that needed to be updated to a newer version. In order for the new version to work I needed to upgrade my SQL Server 7 database to SQL Server 2000. The upgrade went fine for SQL Server 2000 and also with the application. The only problem now is that the compatibility level for the databases stays at 70. Even when I change the compatibility level to 80 it will automatically go back to 80. What is wrong? Please help.
Dear All, what are the advantages of changing compatibility level from 80 to 90? are there any disadvantages doing this on production machine? will it take any downtime? i've searched the google but i didnt get the correct info.

I noticed that a database I am working with has a compatibility level set to SQL Server 2000. The instance is actually SQL Server 2005. I'm guessing that it was created like this because the database originally existed on 2000 and was created via backup/restore.
I'm trying to figure out if this needs to be changed and if so how to go about making the change in a non-disruptive manner. What features of 2005 are turned off as a reult of having a 2000 compatibility level?
I have just upgraded a test server from sql server 2008 sp3 to sql server 2014 inplace upgrade. The compatability level of master database has not upgraded. It was showing 90 and the rest of system databases got updated to 120. Is it fine to update the compatibility level of master database ? Any precautions need to taken??

"Autocommit mode is the default transaction management mode of Microsoft® SQL Server„¢. Every Transact-SQL statement is committed or rolled back when it completes."
"if a statement completes successfully, it is committed; if it encounters any error, it is rolled back. A SQL Server connection operates in autocommit mode whenever this default mode has not been overridden by either explicit or implicit transactions."
My question is, how do we change autocommit mode. I don't want the dml to be commited until i explicitly do commit. This should be default setting.
I want this change either to be made at database level, maybe by doing some setting or through some T-SQL stmt.
I DO NOT want to use anything that has to be done in query windows like set ... off | on in each and every query window i use.
The change has to be done only once and should persist through-out.
How can I change the authentication mode for sqlexpress without going through the UI? I looked at the docs for sp_configure, dmo and smo but I may have missed it. I'd like to be able to run a script that changes the authentication mode of an installed sqlexpress instance from windows only to moxed mode.
What is the impact of changing the recovery mode of a database from Full to simple? The client I am at has set their database to full recovery mode, set their log files to grow automatically. But I don't think they have ever done a backup of their transaction log (it has grown to over 19Gig, where the data portion of the database is only around 400M).
What is the impact of truncating the transaction log now? After truncating it, i would like to shrink the file to a managable number and change the recovery mode to simple (they don't need transaction log backups)
This is my first post and I am a newbie user of SQL Server as well. I am using SQL Server 2005 Express edition. I have also installed SQL Server 2005 Mangement Studio express.
Initially I was under Windows Authetication but today I changed it to mix mode. After doing everything and enabling the authentication for the "sa" user I am getting the following error.
In the login dialog window for the user name I am providing: sa
TITLE: Connect to Server ------------------------------
A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)
When I try the second time it gives this error:

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?
I have a question about change of compability. I want to change compability level from 2000 to 2005 on a very large database with a lot of indexes. I have heard that if I change compability level the indexes will no longer be usable. Is it enough to just rebuild all indexed after I have changed compability level or do I have to do something else?
what are the SS rules around forwards compatibility? For example, I have a SS2014 DB instance but I'm able to query it through SSMS2012 Express. Also, I backed up a SS2012 database and restored it into a SS2014 instance which works as expected. Should I also be able to back up a SS2014 instance that was restored from SS2012 and restore it into a separate SS2012 instance?
In a Data Flow Task, I have an insert that occurs into a SQL Server 2000 table from a fixed width flat file. The SQL Server table that the data goes into is accessed through an OLE DB connection manager that uses the Native OLE DBMicrosoft OLE DB Provider for SQL Server.
In the OLE DB Destination, I changed the access mode from Table or View - fast load to Table or View because I needed to implement OLE DB Destination Error Output. The Error output goes to a SQL Server 2000 table that uses the same connection manager.
The OLE DB Destination Editor Error Output 'Error' option is configured to 'Redirect' the row. 'Set this value to selected cells' is set to 'Fail component'.
Was changing the access mode the simple reason why the insert from the flat file takes so much longer, or could there be other problems?
I have a DB, MDF is about 170GB, log 200GB. When I do a restore of it, the backup takes about 20 minutes to get to 100% but then it just stays there in Restoring Mode.
I have specified the WITH RECOVERY option.
What is happening that it doesn't commit the backup for some reason?
I have a bat file that kicks off a master package, which kicks off about 300 child packages. My bat file is working correctly, however there seems to be issues executing packages in 64 bit mode.
So my question is...
Is there a way to specify in the bat file to execute packages in 32 bit mode and not 64 bit?
bat file: "C:Program FilesMicrosoft SQL Server110DTSBinnDTExec.exe" /f "E:MasterPackage.dtsx"
Is it possible to put master database to single mode, if yes then whats the procedure. The reason behind the scenario is to restore master database from backup for which its strictly recommended to put the database in single mode. But I m not able to do so.
I have created a Transactional Replication Publication on my SQL 2012 server.When I log into another server on the domain running 2008R2 and try to subscribe to the 2012 Publication, I get the following error when clicking on "Add SQL Server Subscriber": "The selected Subscriber does not satisfy the minimum version compatibility level of the selected publication"
The 2012 DB is set as 2008 Compatibility Mode?Am I not able to Publish from 2012 to 2008?.I was using SSMS 2008 to connect to my 2012 Instance, thats why it didn't work...
Secondary replica database(setup in async mode) of AlwaysON went in "restricted mode" during weekly reindex operation.
So I have tried below steps
1) Executed following statement on the same secondary replica database where the issue exists
alter database <DBNAME> set multi_user with rollback immediate
but it failed with the error saying "The operation cannot be performed on database "dbname" because it is involved in a database mirroring session or an availability group. Some operations are not allowed on a database that is participating in a database mirroring session or in an availability group. ALTER DATABASE statement failed."
2) Primary database is multi_user but still tried following command on primary replia database(thinking it will replicate)
alter database <DBNAME> set multi_user
but no luck. The secondary alwaysON database shows (synchronizing) as the alwaysON is set in async mode but the command doesn't replicate across secondary
so we are left with the only option to re-setup alwaysON but I want to avoid it as database size is huge..
I have deployed a project with multiple packages to SSIS 2012 db. I am able to configure the project parameters fine. But, I am not able to replace the package variable values with the 'Environment' variables.
