How are geometries passed to operators… • Step 1: Access path via the parcel’s composite index for the predicate filter to obtain the parcel geometry WHERE a.appraisal < 125000 AND a.zoning = ‘SFR’ Index Parcel’s table ROWID APPRAISAL ZONING AADA… 45000 SFR AABA… 52000 MPR AABA… 59000 SFR AACD… 79000 SFR AACD… 79000 COM AABC… 94000 SFR AABC… 105000 COM AABC… 122000 SFR AABC… 130000 SFR ROWID OBJECTID … SHAPE AADA… 136072 AABA… 852018 AACD… 854211 AABC… 29375 AABC… 482190
