Sorry to hijack this thread, but I'm trying to query and JOIN MySQL tables
using OGRVRT. I tried something similar to the example Steve lists above -
with a CONNECTIONTYPE OGR - but I got an error message that said something
like "msJoinConnect(): Join error. Unsupported join connection type.". Does
this mean that mapserver can't do JOINs to OGR connections?

Thanks,
Greg Luker.
