last paragraph

Oracle is also not relational as per Codd's principals, as it violates the third
principal, and is unable to distinguish between an empty string and a NULL value.

Table 2-3

The table does not list NATIONAL as a prefix for some of the datatypes to
force use of Unicode characters rather than ASCII.

Table 2-3

The table incorrectly lists 'NVARCHAR' as a MySQL datatype. This should be
changed to 'NATIONAL VARCHAR'.

The third example of an outer join is exactly the same as the ANSI style
example - it does not illustrate the preceding point

4th paragraph

The book states that CASE is not supported in Oracle.

>From Oracle 8i rel. 2 (8.1.6), CASE -- WHEN is implemented.

3rd paragraph (last example)

The example description states that the data is being loaded from "sales"
into the "new_sales" table.

In the code, however, it is the contrary: the data goes into "sales2
(INSERT sales ... ) and comes from "new_sales" (... FROM new_sales ...).

2nd paragraph

The ORDER BY clause of the example above this paragraph says

ORDER BY e.fname DESC,
e.lname ASC

Yet the text below it says: "...the result set is sorted by the authors' last names
in descending order..." and "...the authors' first names are sorted in ascending
order."

That should be "FIRST names in descending order" and "LAST names in ascending order".

You mention here in the Oracle section that "select into" for Oracle is to
be used only for assignment of variables in PL/SQL. True, but what the
user is probably looking for is how to emulate the MS SQLServer "select
into" statement in Oracle, which is commonly known as "CTAS", or Create
Table As Select. A simplified syntax is:

Create Table XX as select * from oldtable where y=1

This is a great statement to use while testing or creating test data, so
it's worth mentioning.

Also, why no mention of the UNION command for joining queries? Its an easy
thing to stick in the select area, even if its deprecated.

second heading, "PostgreSQL Notes"

PostgreSQL supports the SQL99 syntax for UPDATE, as described in the previous
section, but it also supports a form such as:

UPDATE table SET col = expression [, ...]
[ FROM fromlist ]
[ WHERE condition ]

where the FROM clause may contain multiple tables to be joined.

See http://www.postgresql.org/users-lounge/docs/7.0/user/sql-update.htm for
the complete PostgreSQL documentation on its forms.
