Support fees & quantity in SQL fields

Hi,
mentioned about a year ago in general discussion thread, please consider support for fees and quantities in SQL fields.
We've had a local hack in place to do this for about a year now, all works well with it for individual registrations.

Also, please provide a variable, such as [ID_EVENT], which can be used in queries.

Once your next release is done I can rework the code against it and upload to git again if you're interested.
Thanks,
Russell.

@tuan is it possible for us to pay for the development / integration? I've got this working so we have [EVENT_ID] in the SQL, and we support quantity and support fee field for SQL. I'd just like to stop having to re-do the code everytime new release. What would it cost to have it developed into the release?

thanks
Russell.
