Put your first query in the from clause of the 2nd: something like that should work: SELECT building.id building.address FROM building, (SELECT event_point.id, event_point.geom, st_buffer(event_point.geom, 100) AS buffergeom FROM public.event_point) buffer WHERE ST_within(building.geom, buffer.buffergeom)


From the ArcSDE Administration Command Reference: Beginning with ArcGIS 10.1, you must use a geoprocessing tool or Python script to create a geodatabase. For geodatabases in Oracle, SQL Server, and PostgreSQL, if you can use the default settings, use the Create Enterprise Geodatabase tool or a Python script that calls this tool. If you want to ...
