[mapserver-users] GetFeatureInfo using MySQL join - additional info

[Dejan Gambin]

I was finally successful with getting data from joined table through GetFeatureInfo. But:

1. It works only for PostgreSQL connection, not with MySQL - is it supposed to be so in MapServer 6? I saw the JOIN documentation changed and there is no MySQL mentioned any more/
2. I get nicely returned data from one-to-many join, using templates (thanks to Ted Spradley post). But gml returns only the main data, not the joined data. Is it supposed to be so?

Thanks very much

regards, dejan
