Deleted and relinked ODBC table but Access still wants old ODBC table.

I am pulling my hair out!!!!

I have tried verything I know to try.

I had a table called Contacts_Table that became ContactsTable . (NO Problems)

started migrating multiple Access DB into one SQL DB on the backend so I created schema's for each front-end.

dbo.ContactsTable became eWRTs.ContactsTable still no issues with the Access 2010 front-end.

renamed eWRTs.ContactsTable to eWRTs.Contacts, now every time Access tries to save anything to the contacts table I get an ODBC error saying it can't find the eWRTs.ContactsTable.

When the FE is launched ALL ODBC linked tables are deleted and relinked.

Updated the Contacts input/modify form to the new table name and it still tries to save to the old table name.

I have tried changing the RecordSource to an imbeded query, SAVE still looks for the old table.

Created new query for the form and set the recordsource to the new query. Still it looks for the old table name.

Created new contacts form from scratch. still save looks for the old ODBC table name.

created new blank Access DB and imported the FE forms, ect. into the blank.
problem is still there.

set the recordsource to the query in the open form event. still looks for the old ODBC table name.

This happens regardless of whether Access is using the OLD {SQL Server} client or the NEWER {SQL Server Native Client V10.0}.

Also, does not matter if the client is XP or Windows 7.

Since I don't have all the functions your code is calling, I am sending you some code we put together several years ago (hopefully it is complete enough for you to get the idea).
Here is what the code was intended for:
1. We migrated our backend from Access to SQL Server.
2. We deploy changes to our Access frontend to 70+ different servers around the world -- each with a unique name. When we do that, we need to automatically relink from our 'test' environment, to their production environment.
3. Under certain conditions (i.e. first time new frontend is opened), we execute code to relink.
4. But before we try to relink, we confirm we can actually make the connection to SQL Server.
5. After the 'planned' relink, we confirm it actually took place.
6. I realize your parameters/settings are different, but you may find something useful in the code.

Code:
Function ReLink_SQLSERVER_Tables()
Dim Cat         As ADOX.Catalog
Dim tdfs        As ADOX.Tables
Dim tdf         As ADOX.Table

Thank you very much.

It will take a couple of days to go through this and see if I can integrate it into my solution.

It interesting how you use line numbers.

Thanks again.

Why did you change from AD trusted connections?

Thanks

John Fuhrman
 
Hi John, can't remember why we went with UID & PWD versus trusted conn - it was 4/5 years ago.
RE line #'S, I inherited a massive Access application that was just being released to 70 sites; was super slow and many errors. Ugh, there were NO error traps anywhere, so if sub1 called sub2, etc., we had no idea where to look. So I wrote some code to apply error traps and line numbers to every piece of code. Then when an error occurred, we logged it and displayed the exact line of code and subroutine where it happened. Combined results from all 70 sites, sorted by frequency, and bingo - there was our prioritized list of what needs fixing!

Sometimes computer problems are like genealogy... The answer to one problem leads to two more!
 
Hey, just so everyone knows. I found the problem.

I am not sure of what was causing the error, but the fix was to delete the old ContactsTable and recreate it as Contacts then migrate in the production data.

Also, trevil620, would it be possible for you to shre the code you created for your error trapping? I have about 20 different Access applications that I am in the process of merging the data and updating the front ends and I think your code could save a lot of time.

Thanks
John F.

Thanks

out of town till Monday.. will send the code then..

The speculative judgment of the quality of an answer is based directly on … what was the question again?
 
John, I just got home; I assume you want a copy of the program that inserts error traps into VBA code, or is it that you just want to see what the code looks like?

The speculative judgment of the quality of an answer is based directly on … what was the question again?
 
Both actually.

If you feel comfortable letting me using it. I got roped into migrating Access DB's to SQL Server and in the process inherited the Access front ends and all the VBA. I have only been doing this for about 2 years and programming really was not my forte'. I was a network admin mainly and could do light programming or scripting when needed.

Now that this seems to be all I am doing I am having to cram and glean as much as possible of examples and a lot of trial and error. One of the ereas that has been particularly tough has been error trapping because everyone has a different idea of how to do it. I particularly like you code with line numbers because as you pointed out, you can quickly find the offending code seqments.



Thanks

John Fuhrman
 
Yes, I can send you the program. I want to make sure it will function correctly in your environment (ADO vs DAO), so I am doing some testing. Re converting to SQL Server, I went thru the same process years ago -- so again I wrote code that would convert all the DAO stuff to ADO, plus all the other differences.

When all else fails, manipulate the data.
 
Thanks TONS!!!! I look forward to seeing your solution.

Thanks

Hi John, sorry for delay - was working out instructions & removing components not associated with 'Adding Error Traps & Inserting Line Numbers in VBA Code'
Here is a link to Dropbox where you will find a document explaining how to use, and an .mdb file with all of the code; there is also the same .mdb, but named as .txt in case your AntiVirus software prevents download of .mdb.
I would appreciate it if you encounter any issues, to please let me know so I can modify the code to handle those situations.
Thank you, and good luck. Wayne

When all else fails, manipulate the data.
