Disadvantages Of Running 80 Compatibility On 2005?

May 1, 2007

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?

Running SQL 2005 Database On 80 Compatibility Mode And DTS Import

Mar 11, 2008


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?

An Argument Against Running Or Developing In SQL Compatibility 8.0 Mode

Oct 29, 2007


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.

Any Compatibility Issues Between SQL 2005 Express And SQL 2005 Server

Apr 1, 2006

Hi All,
The IP company that host my site is installing SQL 2005 soon and I my building a web application with SQL 2005 Express. So the question is has anyone heard of any problems with uploading an 2005 express onto a sql 2005 server? I would like to find out now before I finish all of the work. Don't want to find out later that you can't run a sql 2005 express database on a sql 2005 server.
Thanks for taking the time to read this.

Database Compatibility Between Sql 2005 Standard V/s Sql 2005 64 Bit

Jul 24, 2006

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.

SQL Express 2005 SP2 Compatibility

Apr 3, 2007

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

SQL Server 2005 And RDO Compatibility

Jun 12, 2006

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.


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.

Finding Out Db Compatibility Levels In 2005

Dec 31, 2007

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?

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.

SQL 2005 Replication And Compatibility Levels

Jun 11, 2006

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.

SQL 2005 Upgrade With Compatibility Level 80

Nov 30, 2007

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?


If Microsoft dropped the support for SQL 2000, then would Microsoft support compatibility level 80 in SQL Server 2005?

Problem With Compatibility Between Access 2003 And SQL 2005

Nov 26, 2007

In my office, we offer support for applications developed in Access 2003 in a SQL Server 2000 environment, for some of our clients.

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.

Features Not Supported In Compatibility Level 80 Of SQL Server 2005

Oct 23, 2007

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,

Db Maintenance Plans On SQL 2005 And Dbs In 2000 Compatibility Mode

Nov 15, 2007

Hi All

Im having a problem setting up maintenance plans on one of our SQL 2005 servers but first heres 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 didnt 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. (Im 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

MSSQL 2005: Backward Compatibility Problem With Database Owner

Nov 25, 2005

Hello all,i'm moving all my development to the new 2005/Fw2 environment.Now, i have an MSSQL 2005 server on the development server. To restore an existing database, i've created a new database with MSSQL 2000 compatibility level, and i've restored the backup over it. Everything seems ok, but when i try to create a diagram, i get the following error message:"Database diagram support objects cannot be installed because the database does not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or the ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects."I've checked the properties and there seems to be the right owner (sa). If i create a new database with 2005 compatibility level, everithing works fine.Where is the problem?Also, a side question: by setting compatibility level to 2000, is it correct that the database can be deployed to a 2000 Server environment with no problems?Thanks in advance for any advice. -LV

When i create a new database (using the "New Database" dialog) i cannot set the new database's compatibility level to "SQL Server 2005(90)" because this option is not in the "dropdown list". the only items shown are: "SQL Server 7.0(70)" and "SQL Server 2000(80)". I set the owner to "sa". How do i get "SQL Server 2005(90)" in my "compatibility level" drop down list? Is this an installation option that i missed? Thanks in advance for any assistance!
