Hi,
Does anyone know if it is possible to query multiple fields using
Mapscript's queryByAttributes? If so does anyone have the syntax for this?
I am able to query one field as of right now but would like to be able a
bunch of fields. I am using php/mapscript for this project.
Sean,
I think the trick is to use a query expression instead of a query
item and a query value.
I'm not sure how this works in mapscript exactly, but at the C API
level if you pass a NULL for the query item then the value is
interpreted as a full expression which could be something like:
"[fielda] < 100 and [fieldb] = 75"
... I think.
Anways, hopefully that is an angle to look into.
Best regards,
