Does In-place Upgrade Set Compatibility Level To 9.0
Jun 19, 2007
This may be very obvious and when I get to the first test server I will find out, but I only have a new installation of SQL2K5 so far to test with. I have several databases that need to be upgraded to run on 2K5, but the application requires them to run in 8.0 compatibility. Does this mean that an in-place upgrade is not an option?
I apologize if this is a silly question, but I have not yet found the answer specifically.
Thanks very much.

Hi All,
We were upgraded our databases from 6.5 to 7.0 .After upgrading
the Compatibility level was 65 .We changed to 70 for all databases using sp_dbcmptlevel system stored proc.We were having some problems with Ansi nulls if the compatablity level is 70,We changed back to 65 that works fine--OK with ANSI NULLS.While Upgading ANSI NULLS OFF after upgrading ANSI NULLS OFF.But from the front end side ODBC settings ANSI NULLS are ON.Is that some thing to do with compatablity level or with ANSI NULLS .
If you guys have any great ideas Please let me know.
Thanks A Lot,
VJ

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

Hi,
We are running a test upgrade form sql 2000 standard edition 32 bit to sql 2005 developer edition 32bit. Followed through all the steps and specified the account(SA priveleges and currently used by the 2000 version) and is the local admin on the box for the services and the setup seemed to move fine, except for when it got to the point of installing database services - This is the error message that I got:
MSSQLServer could not be started. Verify you have sufficient priveleges to start system services. The was no choice but to hit cancel and then the set up progressed with a final message of 'SEtup failed'.
Here is a portion of the error log:

Hi there
We found interesting issue which is basically the app is being tested ok on SQL2005 by software vendor. Then we tested in our environment and we found it's not truly true. There are some compatibility issue on SQL syntax. Anyway ... the plan set the compatibility level back to 80 instead 90. Cause this thing for sure is working.
Now my question is do you know any other impacts that you know of if we are doing this setting (running SQLServer 2005 but the database set as 80)? I know that some inbuilt reporting only run 90 level but I can get around this. Performance or something? Is there any thing that I should to know?
Thanks

Having moved over to SQL 2k5, from SQL 7.0 we have now realised that the database's need to be set to comp level 9.0 before they are found in the maintence plan wizard, we currently still access the database using an Access 2000 front end, by changing the comp level will this cause us issues writing data, I'm sure it won't but want to make sure, I'm sure that the comp level just sets what options are available to use.
Thanks

We upgraded from SQL 6.5 to 2000 (.384) and just look at this T-SQL and maybe somebody can tell me what's wrong.
sp_dbcmptlevel appetserv1,80
update articleentrepot set usagermodification = 'MANON' where idarticle = 1
Here is the result:
Cannot use the column prefix 'E'. This must match the object in the UPDATE clause 'ArticleEntrepot'.
When I put the compatibility level to 65, it's works. But my problem is that I need to have the compatibility level to 80 because of the DataMirror replication software and if I do that, my house application doesn't work. I really don't know what to do, I'm in a deadlock. Can you help me!

Hi!
After upgrading SQL Server from 6.5 to 7.0 my production database compatibility level is "65".
I checked that by executing sp_dbcmptlevel <database_name>.
I can change it to "70" but my question is how it's going to affect the application and do I have to change it?
Thank you
Lena

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.

I installed SQL 7.0 on a test server a few days ago. I want to test an application that currently runs on SQL 6.5. I have run a test database through the upgrade wizard without errors. Is there any way to see the compatibility level that the db is running on. I know I can use the sp_dbcmptlevel procedure to make it run at the 6.5 level. I want to see if it is running at that level currently, or if it is at the 7.0 level.
Any help would be appreciated.

Problem: I want to set compatibility_level only when it is greater than 110.
Solution: Select the compatibility level and if it is greater than 110, I alter database set compatibility level=110
ISSUE Irrespective of IF Exist statement the alter database statement is executed all the time.
Here is the sql statement
IF EXISTS (
SELECT * FROM sys.databases where compatibility_level >110 AND name='mydatabase'
)
BEGIN
ALTER DATABASE mydatabase SET COMPATIBILITY_LEVEL = 110
END
What is that I am missing here ?

I'd heard that upgrading SQL 05 to SP2 forced any databases at SQL 2000 compatibility (80) to SQL 2005 compatibility, but I can't find any documentation that says one way or the other.
Can anyone provide insight as to whether or not this is true?
Thanks,

I have an SQL database that I need to detach from an SQL2005 server and reattach to an SQL 2000 database. I tried to set the Compatibility level from SQL Server 2005 (90) to SQL Server 2000 (80). This did not work
Any ideas?

Hi,
While we choose in-place upgrade for upgrading to SQL Server 2005 from SQL Server 2000, does it actually change the code in Stored Procedures/functions also?
e.g. if I have *= in some old procedure does it change it to INNER JOIN while migrating?
Please help me on this ASAP.
Regards,
Rahul

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.

When my app starts up I want to ensure that the database compatibility level has been set to 90. I know about sp_dbcmptlevel, but that only seems to work in an interactive session; the documentation says it can't be used in a stored procedure, and that appears to be true. Does anyone know how I could read the database compatibility level in a stored proc?

I've installed a test instance of SQL 2000 on a test box. I want to try the In-Place upgrade to 2005. I installed 2005 on the test box also, but have been unable to see how to perform the upgrade. I thought running 2005 setup again would prompt me for an instance name .... but it just tells me 2005 is already installed. I must be missing something simple.

Perhaps someone here can give me a hand with this... I have three servers running SQL Server 2000. Two are running Windows Server 2000 SP4 with SQL 2000/SP4 and one Windows Server 2003 with SQL 2000/SP?(probably not 4). I copied the installation DVD to a network drive and successfully performed an in-place upgrade of the Windows Server 2003 machine. However, when I try to upgrade either of the other servers, I get an error indicating that I have a service pack problem.
Reason: Your upgrade is blocked. For more information about upgrade support, see the "Version and Edition Upgrades" and "Hardware and Software Requirements" topics in SQL Server 2005 Setup Help or SQL Server 2005 Books Online.
Service pack requirement check:
Your upgrade is blocked because of service pack requirements. To proceed, apply the required service pack and then rerun SQL Server Setup. For more information about upgrade support, see the Version and Edition Upgrades topic in SQL Server 2005 Setup Help or SQL Server 2005 Books Online.
My SQL 2005 media was probably released before SP4 was released because the Setup Help indicates that you can directly upgrade from SP3, but makes no mention of SP4. I can't imagine there are any migration problems with it since I can't find any reference to it as a problem on any SQL Server sites... So... I'm left wondering what my problem really is...
Any help would be appreciated.

Hi everybody:
We have recently migrated our DDBB from SQL 2000 to SQL 2005 in several Servers. We have 2 DDBB per Server and the size of mdf files are between 10 and 40 GB.
We put Compatibility Level in 90 in SQL 2005 but when we arrive at work we see that our Maintenace Plans failed because the Compatibility Level of one of Data Bases changed to 70.
We have a Trace executing the whole day registrying the execution of stored procedure 'sp_dbcmptlevel' but in despite of Compatibility Level changes, the Trace does not registry anything.
Has anyone passed before me for this situation? Thank you in advance and greetings,
Nuria

We have a reasonably large (several TB) database that was recently migrated from 2008 to a new box running 2014. Before giving it back to the users we forgot to change the compatibility level of the DB to bring it up to date with it's new environment.
We want to do some testing with backup compression so want to change the compatibility level, but we are unsure whether making the change on such a large database would cause slowness or downtime for our users.
Does the process of changing the compatibility level simply allow options that are not available in the older version or does it make structural changes to the database that would cause the users to notice slowness or downtime?

Hello All,
I am in the process of upgrading my current database in SQL Server 2000 to SQL Server 2005. I have finished my analysis using the upgrade advisor and have found a lot of SPs having upgrade related issues. From what I estimate I think it will take around 3-4 weeks to resolve all of those issues. I wanted a quicker way to upgrade my database since we have very little time for the final release. The main reason for upgrade to 2005 was use of new features like Database Mirroring and/or peer to peer replication alongwith the Partitioning features and the new T-SQL enhancements.
The question I wanted to ask was does the compatibility level 80 of SQL Server 2005 supports these new features.
From what I have read on the KB article at http://support.microsoft.com/kb/822400 is that mirroring is supported in any compatibility level, but there is no specific mention on the peer to peer thing.
Also when I personally tried using the New Partitioning Features of 2005 on the database having compatibility 80, it worked fine. Also other features like SQLCLR and TRY...CATCH works fine.
One thing I observed was that new T-SQL statements like PIVOT/UNPIVOT is not supported
It will be nice if someone can give out the entire list of features that will be supported in the compatibility Level 80 and also the list of the ones that are not supported.
Thanks in Advance,
Mitesh

Hi all
I cannot find this info anywhere. We have Hyperion 8.x running against SQL 2000. We will upgrade side-by-side in the coming weeks. It appears that Hyperion 8.x is assured to continue to work without issue with a 2K5 database in 80 compatibility level.
I have seen the BOL table on differences between 80 and 90 (specifically affects us - WITH on Index hints), but what I wonder are about 3 specific features.
1. Do you still get DMV capabilities in 80 mode? (I ran a test on sys.dm_db_index_usage_stats for an 80 compat DB, creating index and using query to hit index, and yes - it does look as if this DMV does get populated).
2. Can you still Table Partition in 80 mode? (Ran a test in DEV, and yes - this does look possible - any gotchas?)
3. Does the optimizer behave quite differently in 80 mode?
I have tested in DEV moving a DB from 80 to 90 and back, and this seems to work with no problems.
TIA from Grand Fenwick!! ;-)

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?
