Subject: [PATCH] In 'Joins between classes' in Section 5 of the tutorial we
have, in the first paragraph:
As an example, say we wish to find all the records that
are in the temperature range of other records. In
effect, we need to compare the temp_lo and temp_hi
attributes of each EMP instance to the temp_lo and
temp_hi attributes of all other EMP instances.
I believe that EMP should read WEATHER, as the example query that
follows joins WEATHER to itself.
EMP is often used in Oracle examples.
Regards,
Graham
