Performing spatial join in Spatialite (QspatiaLite for QGIS)

I'm trying to spatially join and summarize the attributes of a set of buildings to a set of containing parcels. There are (potentially) many buildings to each one parcel.

Here is the query as I'm attempting to run it:

SELECT "MF_with_Zones_atts".'Geometry' AS Geometry,"MF_with_Zones_atts".'PKUID' AS ID,"Apt_Bldg_Footprints".'STATE_ID' AS STATE_ID,"MF_with_Zones_atts".'JURIS_CITY' AS JURISDICTION,"MF_with_Zones_atts".'MAIL_CITY' AS CITY,"MF_with_Zones_atts".'STATE' AS STATE,"MF_with_Zones_atts".'ZIPCODE' AS ZIP,"MF_with_Zones_atts".'COUNTY' AS COUNTY,"MF_with_Zones_atts".'UNITS' AS UNITS,"MF_with_Zones_atts".'UNIT_TYPE' AS UNIT_TYPE,"MF_with_Zones_atts".'ZONE' AS ZONE,"MF_with_Zones_atts".'CMP_' AS CMP,"MF_with_Zones_atts".'OVRLY' AS OVERLAY,"Apt_Bldg_Footprints".'BLDG_USE' as BLDG_USE,"MF_with_Zones_atts".'ZoneMaxDU' as ZoneMaxDU,"MF_with_Zones_atts".'ZoneMaxFAR' as ZoneMaxFAR,count("Apt_Bldg_Footprints".'ROWID' AS BLDG_COUNT,sum("Apt_Bldg_Footprints".'BLDG_SQFT') as BLDG_SQFT,sum("Apt_Bldg_Footprints".'UNITS_RES') as BLDG_UNITS_RES,sum("Apt_Bldg_Footprints".'Bldg_Ftprt') as BLDG_FOOTPRINT,max("Apt_Bldg_Footprints".'NUM_STORY') as NUM_STORY,max("Apt_Bldg_Footprints".'AVG_HEIGHT') as AVG_HEIGHT,max("Apt_Bldg_Footprints".'MAX_HEIGHT') as MAX_HEIGHT,FROM "MF_with_Zones_atts", "Apt_Bldg_Footprints"WHERE Contains("MF_with_Zones_atts", "Apt_Bldg_Footprints")GROUP BY "MF_with_Zones_atts".'ADDRESS'ORDER BY "MF_with_Zones_atts".'ADDRESS'The error messages I get are:

First:

"The SQL query seems to be invalid. near "AS": syntax error

Then:

Unable to read temp table: MF_w_Footprints.tmp Operation cancelled

So, the question is, what am I doing wrong?

Both layers have been imported into a new sqlite database as geometry tables, and I'm using the QspatiaLite plugin for QGis to try to make this happen.
