prop is not joined in the query, this means you're getting horrible performance if this is indeed your query. Perhaps that's your question, what to write to get this property in the query? Is this what you're looking for: #set($sql = ", BaseObject as obj, IntegerProperty as prop where obj.name = doc.fullName and obj.className = 'Sensor Types.SensorTypeClass' and obj.name <> 'Sensor Types.SensorTypeTemplate' and prop.id.id = obj.id and prop.id.name = 'TypeID' order by prop.value asc") In general you join properties with prop.id.id=obj.id, check the property name with prop.id.name='propName', and get the value with prop.value but this last part isn't always like this, there are two exceptions: - StringLists with multiple=true and relational=false use prop.textValue - StringLists with multiple=true and relational=true use prop.list, but you usually have to write: , DBStringListProperty prop join prop.list list [...] prop.id.name = 'propName' and list = 'value' > > ...except for the ??? of course.
