Subject Re: Returning Multiple Resultsets from a Stored Procedure

The last time I checked if one tried firing this:


and decided to send it as a batch request through JDBC ... JDBC *itself* 
will make two
separate round-trips - not one.

Batching "command-type" SQL requests will however succeed in saving 
round-trips ... but
the moment you stick in a "SELECT" type of statement ... JDBC will have 
to return to the
client.  :( 

We investigated this a while back to achieve "chaining" SQL statements 
(collecting them)
through calls to business methods/dao's and only after completing the 
last call, sending
the whole request to the database.  Sounded like a pipe dream.  :)

I don't know how JDBC reacts to Stored procedures with more than one 
"out" resultset?
Does it also make separate roundtrips for each resultset?
