absolute. It also makes it more compliant with the interface
specification in Sun's documentation;
1. absolute(0) should throw an exception.
2. absolute(>num-records) should set the current row to after the last
record in addition to returning false.
3. absolute(<num-records) should set the current row to before the first
record in addition to returning false.
These operations in the existing code just return false and don't change
current_row.
These changes required a minor change to relative(int) since it calls
absolute(int)
The attached patch is against the cvs repository tree as of this morning.
Also, who is in charge of maintaining the jdbc driver? I'm working on
getArray for the jdbc2 driver, but it's going to require three more
classes to be added to the driver, and thus three more source files
in the repository. Is there someone I can contact directly to ask about
this?

It addresses three issues:
1. The problem with ResultSet's interface specifying 1-based indexing was
not quite fixed in 7.0.2. absolute would stop the user form moving to the
first record (record 0 internally).
2. Absolute did not set current_row
3. For field.mod=-1, GetObject would try to return numeric values with a
precision of around 65000. Now GetObject detects when field.mod==-1, and
passes that as the scale to getBigDecimal. getBigDecimal detects when a
-1 is passed and simply does not scale the value returned. You still get
the correct value back, it simply does not tweak the precision.
I'm working off of a source tree I just checked out from the
repository. The diff is based on what was in the repository about ten
minutes ago.

Fixed Statement, so that the update count is valid when an SQL DELETE operation is done.
While fixing the update count, made it easier to get the OID of the last insert as well. Example is in example/basic.java
I'm including a diff of
postgresql-7.0/src/interfaces/jdbc/org/postgresql/jdbc2/ResultSet.java.
I've clearly marked all the fixes I did. Would *someone* who has access
to the cvs please put this in?
