How to add Connection URL properties - MySQL example - SOLVED

Question

As I've spent a long time trying to fix this problem, I thought I would share the solution with the community
OK, here's the scenario - I was getting some sort of error with the SQL being generated by Crystal so I wanted to turn on the debug options for the MySQL JDBC driver.  This is done by adding properties to the connection URL e.g.
I changed
jdbc:mysql://localhost:3306/test
to
jdbc:mysql://localhost:3306/test?profileSQL=true&dumpQueriesOnException=true
The problem is that when I try and use this connection string at runtime, I get an error from the JDBC driver saying that the URL is badly formed and that the parameter
dumpQueriesOnException=true?user=
is wrong.
As you can see, this quite cleary points to some mangling going on inside CR4E that is not taking account of the fact that the URL may already contain a querystring so it should append & rather than ?.
After much messing I found that this is what you need to set your Connection String to;
jdbc:mysql://localhost:3306/test?user={userid}&password={password}&
profileSQL=true&dumpQueriesOnException=true
I presume this is an issue with a lot of databases that expect stuff in the query string of the URL.
I hope it saves someone else some time.
