[mapguide-users] Mix of selectfeature and selectaggregate query

[Dave Wilson]

There is a filter on SelectAggregates just like SelectFeatures. You should be able to add a PostalCode LIKE clause using this if I am not mistaken.

Hi Dave,

The problem with this approach is that I need to narrow down the available
postcodes first (there are many) so I need some way of passing a filter to
the selectaggregates query and I can't see how to do that. The only options
seem to be spatialfilters and groupingfilters, whereas I want a simple text
filter, unless I'm mistaken?

Thanks

Jo
