RE: JAVA Developer

Ask if he has heard about strong typing. Is he going to use strings for dates? 
Does he actualy know there is a date datatype in most of rdbms'es ? Does 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?

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.
