Typos in Oracle Spatial Best Practices doc by Dan Geringer

Question

Hi there,
I was looking through Dan Geringer's notes setting up SDO_JOIN to run in parallel here:
http://download.oracle.com/otndocs/products/spatial/pdf/oow2010/spatial/spatialoow10_bestpractices.pdf
Anyhow, noticed few boo-boos all having to do with table aliases in the examples. They are not too hard to catch but still might trip up folks.
On page 37, the example is missing a table alias of "a". E.g. it should say
CREATE TABLE result1 NOLOGGING PARALLEL 4 AS
SELECT a.rowid1 AS risk_zones_rowid,
a.rowid2 AS parcels_rowid
FROM TABLE (SDO_JOIN ('RISK_ZONES', 'GEOM',
' PARCELS', 'GEOM')) a;but its missing that final "a".
On page 38, the table aliases are incorrect in the relate statement. E.g. it should be
CREATE TABLE result2 NOLOGGING PARALLEL 4 AS
SELECT /*+ ordered use_nl (a,b) use_nl (a,c) */
sdo_geom.relate (b.geom, 'DETERMINE', c.geom, .05) relation,
b.risk_zone_id, c.parcel_id
FROM result1 a, risk_zones b, parcels c
WHERE a.risk_zones_rowid = b.rowid
AND a.parcels_rowid = c.rowid;Nothing too serious but thought I'd point it out.
Cheers,
Paul

Hi Paul,
Thanks for pointing out the typos. Will forward them to Oracle Technical Doc group to have them corrected.
