[mapserver-users] Problem using getShape with MsSql2008 (Mapscript C#)

[Tamas Szekeres]

Paul,

To avoid this problem you might want to set either the buffer parameter of
queryByPoint or layerObj.tolerance to a positive value to avoid passing a
rectangle with no extent to the SQL data source.


Best regards,

Tamas
