Import MDB into SQL Server gives acquireConnection method call to the connection manager error

Posted By : Dan Wilson February 11, 2007 3:06 PM

Here is an annoying MSSQL server problem I just ran into. I am doing a data conversion for a client and I was given an Access DB and as an intermediary step, needed to get it into SQL server. There is a handy (snicker) import tool for doing just that. What should have been a few mouse clicks turned into a few hours of dueling.

As the import routine ran, it would consistantly fail at 'Prepare to Execute'. The error message was:

No problem, it seems to be a connection problem. I'll just verify the connection and run it again.

Failed again? Maybe I need to set a DB password and that will fix it

Ok, I can't set a password unless I close the Access DB, open it again, select Open Exclusive, and Open. No problem, let me just do that and set the password. Verify the connection again... Verified. Perfect, now let me import the tables again...

Failed.

Same error

Maybe if I yell at it a few times it will work. Ok, maybe yelling doesn't help... same error.

A few pages into a google search I find out there is a 64 table limit on importing.. Thank you guys/girls at SQL Junkies!

So, apart from the catharsis of writing this post, i'll feel a lot better if posting this on the net helps someone else.

P.S. I am still scratching my head at the arbitrary 64 table limit.
