sorry that the humor didn't come through in the email. i was laughing quite a
bit as I was pretending I was the db ignorant java guy.

Subject: RE: JAVA Developer
just for some fun..
if he is a good productive java developer, he probably doesn't bother with
all that type of stuff.. he says that's what the java container and/or O/R
Mapping tools do for you..
He will say, I use Oracle's toplink/ADF BC or hibernate and I map objects
to tables, and it generates the SQL with all the bind variables. no need for
interfacing with your stored procedures, no need for worrying about pagination
(it does that).
Be prepared for that type of thing and don't immediately dismiss the O/R
mapping tools as a viable means for mundane persistence or the preferred J2EE
developers approach.
those tools (toplink anyway), supports stored procedures, so you can still
reign in those kind of folks if you need to. :)
ADF BC (the follow-on java framework that replaces forms), is another
bind-variable, pagination database friendly framework for retrieving/persisting
data.

Ask if he has heard about strong typing. Is he going to use strings for

he suspect that date may be a datetime in some of them? Is he going to rely on
implicit conversion or he already knows there is a function to convert string
to/from date ? May be he even knows that format mask can be explicitely
specified ?
Ask if he has heard about bind variables to start with. Then ask how he is
going to implement them. Ask to show (pseudo)code samples.
The ask some more advanced questions like what he thinks how rdbms finds
one particular row out of 100T rows? Does he suspect that "where like '%java%'"
can be tricky? May be he even has an idea how rdbms can order rows? May be he
suspects that condition (b=1 or a=2) can be a culprit?
May be he has some idea that statement.execute means some network
roundtrips to the server?

Subject: JAVA Developer
We are getting ready to hire a JAVA Developer, and I was asked if I wanted
to ask some questions relating to the database.... or to see if we get along.
Connection pooling comes to mind, not imbedding code that would become a
cpu issue, etc.
Not having much experience with Java, do anyone have questions I could
entertain? Some of you may have had such an experience already, and could pass
on a couple questions you wish you had asked, or would ask next time.
