Hi Rick! The toolbox support two distinct styles of file access. The first
is the standard SQL-oriented access of JDBC, which allows you to create a
cursor and then move through it, but repositioning randomly (especially
based on key) is not particularly easy. You can't, for example, create a
result set starting at a given key value and then position yourself
BACKWARDS one record (along the lines of a SETGT, READP).

Well, that answers one of my questions... That was exactly what I
hoped to be able to do...;)

Wouldn't using ResultSet#previous() accomplish the same thing as a READP?
Though i'm really not sure why you would want to use this idiom in
sql. I think the
need for SETGT/READP arose from the inability to dynamically sort records
in RPG.
