I just read through Chapter 7 of the PostgreSQL docs (
http://www.postgresql.org/docs/8.2/static/queries.html) regarding queries,
and could find no examples or mention of a sub-query used in the select
list. For example:
SELECT t1.foo, (SELECT COUNT(t2.id) FROM tblTwo t2 WHERE t2.id = t1.id) AS

Sweet! Sorry about that Jochem, I read the one Chapter (7), but didn't

Thanks for the reply. Do you currently run MySQL and/or PostgreSQL on
Windows boxes? If so, what version(s) for both the db server and windows
servers?
The cost is currently not an issue, although it certainly has the potential
to become one in the relatively near future, at the current

I agree, I think every database has some non-standard SQL.
An example in MS SQL is the isNull() function, which is
functionally equivalent to the ANSI standard coalesce(). Why
did MS make their own? Who knows, maybe because they liked
their name better?
SQL Server also supports

Both. 8.2 for Postgres and 5.1 for MySQL.XP Pro and Server 2003
for the OS.
SQL Server also supports COALESCE. And, while the two are very similar,
they
aren't identical in functionality. A Google search on coalesce vs isnull
turns up all sorts of mildly interesting stuff.
You're right on both counts, Dave. My main point was that MS even bothered

database like that when you can get essentially the same thing for free

Thanks for the clarification.

Jochem,
I was hoping that you would respond. I've seen a number of your posts
regarding PostgreSQL, and certainly wanted your opinion. :-)
We all know what opinions are like, which is why I didn't want to just take
my friend's opinion as the end-all official truth. Thanks to you all, I
Are you aware of anyone who currently runs MS SQL in case
sensitive mode? I'd be curious to know how often that happens.
Quite a few people do this, in my experience. You can specify different
collations for each database within an instance. Collations determine other
things in addition to

It is different to SQL Server, but that doesn't mean that SQL Server is
standard compliant either. In 8.x they've made many tweaks to make it even
more standards compliant in its syntax, so please have him check his facts.

Matt,
I'll offer my 2 cents:
I use both Pg and MySQL daily now. I used MSSQL for quite a time,
but being a small company, when I started to think about scaleability
and long-term costs I moved all of my projects over to MySQL.
Most of my external projects, however, run Pg, so I spend quite
