[Mapserver-dev] Re: layer queryByShape and SDE

[Peter Slootweg]

Not sure if it is related but,

does your SDE layer have any records with a NULL in the SPATIAL (usually 
named SHAPE) column.

we have run into an issue using the SDE api directly(and via MO) where 
searchbyshape fails because of a NULL value in the 
spatial_column(SHAPE). One possible way around this is to exclude the 
NULL shapes from your query e.g. add "AND SHAPE is not NULL"

not sure how this translates into Mapserver/Python wrappers.
