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?

1) adds NetBSD shared lib support on both ELF and a.out platforms
2) replaces "-L$(LIBPQDIR) -lpq" with "$(LIBPQ)" defined in
Makefile.global. This makes it much easier to build stuff in
the source tree after you've already installed the libraries.
3) adds TEMPLATEDIR in Makefile.global that indicates where the
database templates are stored. This separates the template files
from real libraries that are installed in $(LIBDIR).
4) changes include order of <readline/readline.h> and <readline.h>.
The latest GNU readline installs its headers under a readline
subdirectory.
In addition to applying the patch below the following files need to be copied:
backend/port/dynloader:
bsd.h -> netbsd.h
bsd.c -> netbsd.c
include/port:
bsd.h -> netbsd.h
makefiles:
Makefile.bsd -> Makefile.netbsd
It would be great to see this incorporated into the source tree before
the 7.0 release is cut.
Thanks!

the handling of negative numbers and commas. The attached path attempts
to fix these.
However the getValue method does not yet insert commas into the
generated string.
Also in getValue there is an incorrect assumption that the currency
symbol is '$', it should of course be '£'!. I have no idea on how to go
about fixing this one.

This implements some of the JDBC2 methods, fixes a bug introduced into the
JDBC1 portion of the driver, and introduces a new example, showing how to
use the CORBA ORB thats in Java2 with JDBC.
The Tar file contains the new files, the diff the changes to the others.
CHANGELOG is separate as I forgot to make a .orig ;-)
file containing the latest version of the JDBC driver, allowing it to be
compiled and used under JDK 1.2 and later.
NB: None (well almost none) of the new methods actually do anything. This
release only handles getting it to compile and run. Now this is done, I'll
start working on implementing the new stuff.
Now this tar file replaces everything under src/interfaces/jdbc. I had to
do it this way, rather than diffs, because most of the classes under the
postgresql subdirectory have moved to a new directory under that one, to
enable the support of the two JDBC standards.
Here's a list of files in the tar file. Any file not listed here (in the
postgresql directory) will have to be deleted, otherwise it could cause
the driver to fail:

When importing an image into the database, the example now fires off a
new
Thread, which imports the image in the background. This also means that
the application doesn't freeze on the user, and they can still browse
the
images in the database, while the upload is running.
This now makes the ImageViewer a true example on how to use Threads (the
threadtest class is just that - a test).

important step towards making the driver compliant, and means that for
some Java applications and servlets, only a single database connection
is
needed, so in a sence this is a nice little show stopper for 6.4 (and
should still be backward compatible to 6.3.2).

Bug fixes:
PreparedStatement.setObject didn't handle short's
ResultSet.getDate() now handles null dates (returns null rather
than a NullPointerException)
ResultSetMetaData.getPrecision() now returns 0 for VARCHAR
New features:
Field now caches the typename->oid in a Hashtable to speed things
up. It removes the need for some unnecessary queries to the
backend.
PreparedStatement.toString() now returns the sql statement that
it will send to the backend. Before it did nothing.
DatabaseMetaData.getTypeInfo() now does something.

This fixes a problem in ResultSet.getDate() when the column is NULL
(reported by Vincent Partington <Vincent.Partington@nmg.nl>)
And fixes a problem with Field's (ResultSet.getObject() was proving to be
slow as it repetedly send queries for oid -> name mapping - fixed by
creating a cache. (reported by Mario Ellebrecht <ellebrec@nads.de>)
Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.
It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.
This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )
This patch is against the 6.3 sources, as it took a while to
complete.
Please review and apply,
Cheers,

1) DatabaseMetaData.getPrimaryKeys() would fail saying that there
is no
table t.
2) PreparedStatement.getObject() was missing some break statements,
which
was causing updates not to work with JBuilder (supplied by Aaron
Dunlop).
