RE: Re[2]: Question using jdbc/jt400

From: MidRange

Hi Joe,

Thanks for responding Joe.

In regard to the code :

while (readCommandA.next())
{
if(some condition dealing with data from row in readCommandA)
{
while (readCommandB.next())
{
updateCommand1.execute();
}
}
}

Is 'readCommandA' a ResultSet? I'm not sure how to relate this to
my situation where the user decides dynamically whether to go
forward or backward and one record set is retrieved at a time. And
due to late breaking changes in the db I don't really want to load
an entire list - and it would be rather large anyway.

To be honest, I don't really recognize the code above. A standard JDBC 2.0
applications looks more like this:

Statement stmt = connection.createStatement(
ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet resultSet = stmt.executeQuery("SELECT * FROM myfile");
// Move cursor to the row to update
resultSet.first();
resultSet.updateString("fieldname", "newvalue");
resultSet.updateRow();

Basically, you create an updatable result set and you can iterate through
it, then update each record just like you would with a READ and an UPDATE in
RPG. You can also insert new records, just like a WRITE statement.
