Hi All
may be my post sounds stupid but i have on idea about it.
can some one there please clear what is relationship between MDAC and SQL Server. id MDAC part of SQL Server or it is optional tool for some thing else. what it is excatly and links to useful tutorial etc.
I have created an Access2003 project (existing data) that links to external data. First I connected to a SQL Server 2000 database. Success. Then I tried to set up a Transact SQL data connection to a legacy MDW-secured Access97 database. (A third-party VB6 application goes against it, and we don't have the source code, so we cannot upgrade it.)
The Transact SQL link tests OK but I cannot select any of the tables or queries from the list presented. However, with the same credentials, I can use these same objects in Excel 2003.
When setting up the link in Access2003, I specify JET 4.0 OLE DB Provider, I enter the MDW file on the All tab, a username and a password on the Connection tab where I browse to the MDB file, and specify Shared Deny None on the Advanced tab. When I test the connection, it tests OK ("Test connection succeeded"). Yet on the "Select the Database and Table/Cube which contains the data you want" dialog, "(Default)" appears in the grayed-out dropdown. Then, beneath that dropdown, there is a grid with Name and Description columns. The grid contains query names but the grid is not enabled. The list of queries is this table is grayed out. Neither of the scrollbars works.
BUT... if I use the SAME username and password in Excel2003, and specify the same MDW, there is no problem working with these same database objects in the legacy Access97 database. WHAT IS DIFFERENT ABOUT THE WIZARD IN EXCEL THAT ALLOWS IT TO SUCCEED AND THE WIZARD IN ACCESS THAT CAUSES IT TO FAIL HERE? In Excel, the list of available providers says Microsoft Access Driver, not JET 4.0 OLE DB Provider.
Thanks

When trying to link to an SQL table in Access 2003, the software appears to be malfunctioning.
The sequence of events is File - Get External Data - Link Tables - Files of Type: ODBC Databases().
The Problem: On two of my computers, the select data source window does not pop up, preventing me from linking to any ODBC data source.
Observations: This function has worked normally in the recent past and works on other computers running Access 2003. One difference between the computers working and non-working computers is Norton Antivirus 2006 (recent upgrade).
Has anyone experienced anything like this? What's going on?
We are in the process to upgrading from SQL 7.0 SP1 on a NT 4 EE sp6a active/passive cluster to a SQL 2K SP2 on the same NT 4 EE sp6a active/passive (single instance I think it is called now) cluster.
My question now is about MDAC.
Do I need to upgrade all my clients (W98 SE) that actually have MDAC 2.5 installed to the 2.6 version of the product?
Is there any MS articles that clearly explain this argument?
Thank you in advance.
Best Regards.

Ive got a question on MDAC and SQL 2000.
We have a SQL Server 7.0 running on NT 4.0 with MDAC 2.1 installed.
We also have a SQL Server 2000 running on Windows 2000 with MDAC 2.6 installed, as well as other instances of 7.0 and 2000.
I am trying to setup Push replication from the box with SQL 7.0 and MDAC 2.1 installed to a 2000 server with MDAC 2.6.
A SQL 7 to 2000 push works if an instance of 7 and 2000 are installed on the same machine. I can push to any remote machine, except for the one server with MDAC 2.1 installed.
Could MDAC be my problem?
Thanks,
Kyle
We have a large project that is importing msado21.tlb. We want to import least msado25.tlb to access the ADODB::_Stream object, but are unsure what exactly this entails. I've noticed no problems testing that change, but I cannot find any changelog for the MDAC upgrade. Is anyone aware of, or can point me to, a list of changes (fixes, modifications, caveats, etc) between MDAC 2.1 and MDAC 2.5? The binary msado file is always much newer, of course, but we want to link with the older type libraries to maintain maximum compatibility.
Any help is appreciated, I'm at a dead end!
How to find out what version of MDAC is running on the server?

Thank you.

Hi folks. Got a real doozy going. One of the network techs reinstalled NT4 SP5 on a server. This reverted the SQL driver back to 2.something. Now sqlserveragent jobs will not run.
I have tried to instal MDAC 2.5, but it doesn't change the driver up to the new 3.xxx driver. I searched around on here and folks said that you have to move the MDAC executable to a new directory. for the new MDAC I don't see MDAC.EXE. I did find MDAC.COM and renamed that. Tried to rerun MDAC 2.5 but still got the old SQLSRV32.Dll.
Uninstalled SQLServer and reinstalled. still got the old SQLSRV32.Dll.
Tried to apply SQLServer SP1. It died.
Found that I am to shutdown some services. Did that. SP1 still dies.
Tried to apply SQLSERVER SP2. It tries to pick up where it died and it dies again.
SO, I'm currently uninstalling SQLServer, reboot, installing SQLServer, reboot, Trying SP2 again.
Didn't think that it was brain surgery just to install a new flippin version of the ODBC driver.. SHEEZ!!!!
I'm in a mild-debate with some colleagues of mine.
Can someone shed some light on this for me.
(This is related to a problem we are having with empty recordsets being returned where we know there should be rows returned. I think it could be caused by incorrect/outdated MDAC components.)
We use SQL 7 sp2, and ado DSN'less connection strings.
MSSQL .7.0 SP2
WIN2KPRO
ATI 32mb video
1.3gh AMD
1g Ram
No other apps are affected....my once fast system is slowed to a crawl. 5+gb
free on C 37gb on E and NO apps loaded in systray. NO background processes,
nunca.
I installed MDAC 2.6 on a system to try to correct an OLE error when using
sp_OACreate that causes an ODBC connection broken and shuts down SQL every
other execution.
***** Now, the system is running slow, I tried reinstalling, moving the data
to a single local drive. (No other apps appear to be slowed)
Uninstalled MDAC 2.6 and reverted to 2.5 still slow.
Reinstalling MSSQL 7 and SP2, and MDAC 2.5 still slow...
As an example, when a simple xp_cmdShell 'dir c:mssql7data*data.mdf' the
resulting 10 lines are slowing typed accross the screen. On most systems
the text is refreshed so fast we only see a flicker.
Cleaning the registry still slow... Profiler shows DML and GHost lines that
appear to suck the life out my system, but its only pegged at 2%, like it's
doing something, but what(?)
Tonight I may have to reformat and reload, however I've seen this before and
would really like a clue.

TIA

I installed MDAC 2.6 SP1 on my 2000 machine in order to get SQL server 7.0 to work properly on my machine. I'm trying to get installed on server which is on NT 4.0 SP6 so that when I save a DTS package on my 2000 machine and run it on the server it doesn't get the error client access ODBC driver not capable. I intalled MDAC 2.6 SP1 on the server but it doesn't look like its updating it. The install goes fine. I reboot but when I go into the ODBC connections and look at the driver for the client acceess it still has version 6.00.00.05 while my 2000 machine says 6.00.07.00
Any ideas on why its not updating. Can I just take the DWBODBC.DLL from my machine and copy it to the server?
While installing SQL 7.0 on nt4/sp6 it hangs during the MDAC portion.
The copying of files is succesfull but when it goes to the MDAC portion it hangs.
Hi,
I have a SQL 7 Server running SP2/MDAC 2.5. One of my techs accidentally loaded mdac 2.6 on a machine and it no longer could establish ODBC connections to my SQL server. I used the CC check utility to roll it back, but was wondering why the 2.6 client could no longer attach to my server. In the past I have had 2.1 on my server with 2.5 clients that connected with very few problems. At least not a major one like a failing ODBC connection. Do I need to upgrade my server to 2.6 before my clients?
i was wondering if there is anyway to downgrade the MDAC to 2.5 (or specicifically the sqlsrv32.dll to 3.70.06.23) on an XP machine?
WHY? - http://www.dbforums.com/t1043791.html
it seems that starting with MDAC 2.8 the FETCH NEXT statement for cursors requires an INTO clause. otherwise an unspecified error is returned.
so it's not possible to scroll through the records anymore without storing the values of the fields into local variables?
Hi all,
About to start a project to upgrade to MDAC 2.8 from MDAC 2.6 on a number of servers. Has anyone encountered any issues with this? Also, if we do NOT upgrade several client workstations, might we expect problems as a result?
We are aware that we need to patch MDAC for the vulnerability issues, but we are trying to comine this with a server upgrade for servers at risk. Has anyone had experience on a similar project?
Cheers,
Dun
I am trying to load a project under VS2005 under Windows Vista that references an ADOX wrapper that is looking for version 2.8.0.0. The reference fails because the library is not registered.
I thought maybe installing MDAC 2.8 would solve my problems, but when I run the installer for that, it briefly puts up a dialog that it is extracting files, then it disappears.
Any ideas?

What kind of components does MDAC 2.8 SP1 give you for Visual Studio 2005? Thanks!
View 1 Replies View RelatedHi, I have troubles with a threaded application on W2003 server. It seems to leave open connections behind time to time, it sums to hundreds over a day (the application make thousends). It is using the SQL ADO provider, MDAC 2.82.1830.0, SQL Server 8.00.2039 (SP4), Windows 5.2 (3790).
Is there a knwon bug like this? Is there a way to trace the ADO provider?
This question relates to the optional installation component MDAC which upgrades the version of the ODBC driver you use.
Microsoft has indicated that any ODBC driver BELOW 2.5 has not been tested and is not year 2000 compliant. Anything between 2.5 and 3.0 they are testing and is not certified. 3.0 and above is compliant.
However, the NT 4.0 Fix pack #4 installs version 3.60.0319 and the SQL server Fix pack 5 and 5a install 3.70. something.
Most of my Production servers and clients have 2.65. something.
How are people handling this issue to ensure year 2000 compliance?
We already have one vendor's software who is warning us NOT to install this component because their software will not work.
I would like to use the most current version possible.
Any input would be appreciated........Craig
I am new to MS SQL 2000 and have a couple of questions. First, how do you check the version of MDAC that Windows 2003 server is running and second, how do you determine what service pack that SQL is at.
I am having issues of extreme slowness using ODBC. I checked to see that tracing was not enabled and found that it wasn't. I am using TCP/IP for the connection.
Thanks

I am running SQLServer 2005 on Windows XP sp2.
I can't build a data connection in BIDS (error 80040154), and I checked the internet for possible solutions.
I downloaded Microsoft Component Checker and it informed me that I had a mismatch with MDAC 2.8 SP1 and XP SP2.
Specifically SQLOLEDB.dll (expected 2000.85.1117.0) and MSXML3.dll (expected 8.50.2162.0) and SQLXMLX.rll (expected 2000.85.1117.0) seem to be mismatched.
There are all kinds of instructions on the web for various fixes, and I am not certain what is current.
What do I need to load/uninstall in order to fix this problem?
Thanks very much...Marv
I just updated MDAC on one of my machines and I'm now having trouble accessing my SQL server. It's a local connection using SQLOLEDB in a VB dll. It was working fine before the update and now I get:
Microsoft OLE DB Provider for SQL Server error '80004005'
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied.
/cms25/CMS.asp, line 33
Most of the information I can find on this refers to TCP/IP connections but the SQL server is local. My connect function looks like this:
Public Sub ADOConnect()
With m_ADOConnection
.Provider = "SQLOLEDB"
.CursorLocation = adOpenStatic
.CommandTimeout = 20
.Mode = adModeReadWrite
.ConnectionString = "Data Source=" & m_strServer & ";Database=" & m_strName & ";" & m_strUsernamePassword
.open
End With
End Sub
On this server, m_strServer = "(local)". What am I missing? Thanks for any help in advance!
