OracleSpatial and combinations of those. As you maybe have seen from my latest questions,
I’m using MapScript in csharp. It has been some work to solve my problems

is a similar for OracleSpatial) and the rect argument will always have a value.
Wouldn’t be nice if the rect could be null (and not used) if I haven’t
told it to be used. Either that, or another function with no rect argument,
which only queries attributes. <o:p></o:p></span></font></p>
