Anyone have any experience configuring PhotoGallery to use a backend mySQL database?

The application connects successfully for Read operations, but no amount of troubleshooting can get it to Write records to the tables.

Your going to have a lot of problems and a lot of the code will have to be re-written.

There are a lot of things in the the code that the MYSQL database system does not support or has issues with . I know because I once made a version of ASPBanner work with MYSQL and it took weeks of work to get it stable.

Null field types can cause problems... but mostly ADO updates which I don't think MYSQL supports at all. All of the ADO stuff would have have to be rewritten.. etc etc

That's probably why you cant get much of the code to write to the database.


Here is a generic example.

An update to an existing record using ADO
http://www.powerasp.com/content/database/ado_update.asp

And update to an existing record using an update query.
http://www.powerasp.com/content/database/using_update.asp

All through the the code the ADO updates would have to converted to update queries which means a lot of work.

I used ADO a lot because I like it and it is little easier to validate data before it is written to the database.

It is also a little easier for customers to understand when they look at the code.

Anyway....

The app just was not designed to work with MYSQL.
It was specifically designed to work with MSSQL and MSACCESS only.

This holds true for all of our applications.

Your running off an IIS 5 Server so I would suggest just using MSACCESS as the database. The Photo Gallery app will run very well using MSACCESS.

I would say that it isn't all that difficult using mySQL for the backend....the main thing is to make sure you set the primary keys for auto-incrementing in your database.  Alos need to make sure that any DELETE SQL statements are formatted like this

DELETE FROM tblName WHERE tblField=SomeValue

and not

DELETE * FROM tblName WHERE tblField=SomeValue

The same holds true for using MSSQL

I disagree...

It would be 20 hours + of conversion and testing. Maybe more.

Like I said, I converted a version fo ASPBanner once to work with MYSQL. It took forever to change all the code (2 weeks of messing around) and get it working. There were also a lot of issues with null values in the database, ado update code that had to be rewritten, cursor type issues, recordcounts not working, etc etc that had to be sorted out. There was a ton of situations where things seemed to be working but later on I noticed there were minor bugs to deal with. It was a lot of work.

ASP Photo Gallery has a ton of asp pages. It is a much larger app then ASPBanner. If you convert it to work with mysql I highly doubt you could have it running well with less than 20+ hours of work. I wrote the app and it would at least take me that long and there would still be bugs at that point.

If you think you could your not used to my style of coding and don't realize exactly how much stuff needs to be rewritten.

Granted, you could get some of the basics running off mysql in a few hours or less but there is just so much little stuff that would give you trouble.
