Conversion of Access back end to MySQL without tools

I'm converting an Access back end database to MySQL.  It is exceedingly difficult for me to get permission to install one of the vendor tools for conversion on my network.  I know there are problems with maintaining table relationships in moving the table structure and data.  Any pointers on excellent articles on moving the database to MySQL maintaining as much structure as possible would be most helpful.  Most articles point to tools and I cannot get permission to install ANYTHING on this network.  I'm running Access 2010, about 300MB of data, 30 tables or so.  Thanks in advance.

Curious, what is your experience level with mySQL?  Have you built Access solutions using a mySQL back end?

When I first stat learn to use a new flavor of  SQL Server as a back end for Access I do not use any tools. I build all the tables manually.  I then create append queries to move the data. I do lots of testing. Fix issues with data types not compatible with Access. Tweak code. Rinse and repeat.

I learned a lot really fast by not using any conversions tools. In fact, of all the conversion tools I have tone has  ever be  100%  compatible with Access. I you first do then  manually, you will learn what to look for when you do use a conversion tool.


There are some great tools and information on other site but I cant post any links here.

My experience level with MySQL is about zero.  I'm all for learning to do it by hand first before using a tool but there are dozens of relationships.  Though I suspect that's what I need to do.  There was a solution out on one of the blogs which changed the permissions to the hidden relationships table (MSys something) inside Access and this allowed an automated way to build the relationships in MySQL but I can't find it again.

Other ideas welcome.

No need to unhide  the msys tables, Just use DAO to read the table and relationships collections.

Check out the example attached in my previous post. It will show you how to read all the data structures and relationships.  It will even generate a script to recreate the entire database including relationships.

30 tables or so.
If you have lots of database with different structures then a tool might help save time. With a single database with 30 tables or so you could easily manually build the database and relationships in less time than it will takes to learn a new tool.  

My experience level with MySQL is about zero.
Upsizing an Access back end to any SQL Server is not as simple as run a tool to import the tables, relink and your good to go.

You are really going to need a development sandbox (geek speak for test environment) where you have a separate mySQL server for development and testing. You will also need to be able to install developer tools.

I have sandbox - no problem - I'm using separate mysql instance for dev and test and production.  I can install developer tools but it can take 2-3 months to get them approved for my network so a real pain and can't wait on them.  I know - I know - this environment is incredibly difficult to get things done but I can't export this whole thing to a different environment and has 30K VBA  -a bit of a challenge.

I feel your pain. Using VMs has really made it easier for me.

Can you not install any developer type tools even in your sandbox not the network?

Since you can install mySQL Server, can you also install the WorkBench from mySQL (not third party) that allows you to manage the databases?

MySQL GUI Tools http://dev.mysql.com/downloads/gui-tools/5.0.html which is a free package.

Yes - I have workbench - full suite of whatever from MySQL.  Just a real struggle to get something installed on my windows machine which might require admin rights to install - everything has to be approved if it requires admin rights - they are very particular about getting approval for anything on this network.  understandably so but still, makes it a pain -

thanks checking out the helpful links, etc.

WOW. That is really strict. Hard to do development if you do not have admin right to at least you dev machine.
 
Hopefully you can look at the 1553923-Scripting-Access-Tables-ver2.zip I attached in a previous post. Hopefully it will teach you a lot about the inner working of Access tables and relationships.

Did you know Access has a built-in Documentor that will print the table designs and relationships detail?

Yes - I've used that and written some VBA which grabs some of that information (not relationships but does simple things like counts, reports of the forms, etc).

This thing was given to me as a working access simple (single huge file - no backends) - and they want to convert to MySQL for several reasons... I suspect it will be slower with the network in the middle of database work.

anyway - thanks - yes I saw your zip file and was looking at it - big help.

It is true that simply migrating the tables to any flavor of SQL server back end is not a guarantee for increased performance without any design changes to both the front end and back end

 With some design changes you can see significant improvement over slower networks when the concurrent user count is over 7-10 or the Access back end is over about 500 meg.

Normally  I find that I am able to get better performance with a true Client Server back end than with a Access back end on the same network.  

If the was not a previously split database then you may have other issues with the design not being linked table friendly.

You have some work ahead of you.
