I'm writing an application to allow migration of databases from one type to another.  The application will handle Access, SQL Server and MySQL database once it's done.

At the moment, I'm very happy with handling Access and SQL Server stuff, but I can't even create a connection to the MySQL server.

Can someone please advise me as to why I can't simply populate a connection string and set connected:=true to open a database connection to a MySQL server?

I'm using TADOConnection and TADOQuery to connect & read/write the databases.  I don't understand why this should be a problem as I have used loads of database types whilst programming before and have never come across this problem.

Thanks in advance,

AFAIK, there's no ADO provider for MySQL. There's one for MS-SQL, though. Spelled almost similar. To connect to MySQL you'll need an ODBC driver for it and connect through ADO to ODBC to MySQL.

Could you explain a little more, maybe with a code example please.

I'm currently using this connection string....

"Driver={MySQL ODBC 3.51 Driver};Port=3306;Option=3;Server=Development;Database=TestDB;USER=root;PASSWORD=;"

Actually, don't bother - I've just reread what you've said and that's basically what I'm already doing.

Actually, there are some ADO drivers for MySQL. Never tried any of them myself - thought I would, so I had done a little research.  ADO.Net for MySql on Sourceforge.net and ByteFX.data on ByteFX.com also SevenObjects on SevenObjects.com
