Re: [JDBC] JDBC SQLCodes or Error Numbers - Or how to handle errors

It appears the getBytes was previously being used to return a byte array of any arbitrary column. Fixes for blobs seem to have broken this. The question is as Jason pointed out which do we fix.

[JDBC] JDBC SQLCodes or Error Numbers - Or how to handle errors
I'm new to postgresql and it's JDBC driver, although an old hand a relation databases. I'm trying to rely on past practices in developing some code using Java and postgresql. I'm trying to do a INSERT into a table with the full knowledge that I might be trying to insert a duplicate row (which won't be allowed by the Primary Key). Since 80% of the inserts will succeed (because I don't expect many duplicates) I didn't want to waste programming time or runtime by doing a select to first see if the data existed. I'm used to just doing the insert and catching the SQLCODE -803 on DB2 to know that the row I'm trying to insert already exists. Is there an easy way to do this using Postgresql and JDBC? Postgresql version is 7.1.3 JDBC driver is the one that I compiled from the 7.1.3 installation I'm using the Java SDK 1.3.1_01 -- So is my only hope trying to "match" the error text and determine what when wrong?

Re: [JDBC] JDBC executeUpdate() does not return the number of rows effected
Barry, I was using Postgresql V7.1.3 and driver version 7.1-1.2. However, last night I downloaded 7.1-1.2 again and noticed that it was a few K larger, even though it had the exact same version number. When I tested with the "new" 7.1-1.2 (93,011 bytes vs approx 88K), executeUpdate() *did* return the correct row count. Go figure!? So it appears to be fixed in the newest code base.

Re: [JDBC] DatabaseMetaData.getImported/ExportedKeys() patch
Hi all,
I'm not sure, but these are the methods which allow an external
application (i.e. an ERD tool) to query a database and know the
relationships between the tables aren't they?
If so, this is a very important feature which, once implemented
properly, will allow Java tools and programs (for example the ERD tool
"DbDesigner", etc) to work correctly with PostgreSQL.
Given that these are the methods I'm thinking about, I hope this patch
is completed properly and accepted into the JDBC driver asap, even
though we are in beta. We have plenty of time to ensure things work
properly before final release.
:-)
Regards and best wishes,
Justin Clift

[JDBC] Error: ClassNotFoundException
Hello All,
I'm a fairly experienced developer, however, a complete newbie when it
comes to using PostgreSQL and JDBC. I have successfully installed
PostgreSQL on my Mac G4 running Mac OS X 10.1. I'm able to start the DB
daemon (with -i extension), I've created and populated a database (can
query the database, etc.). When I installed PostgreSQL, I created a
user account named "postgres" on my computer, and start the DB daemon
while logged onto that account (in a console window after logging into
the postgres account using 'su - postgres'). I've downloaded the
pre-compliled jdbc7.1-1.1.jar JDBC driver. I put the JDBC driver file
in /usr/local/pgsql/share/java. I've been trying to use JDBC to connect
to a database and started with Marc Liyanage's example source file.
When I try and run the executable after compilation I get an error.
Specifically, the line of code in
"Class.forName("org.postgresql.Driver");" returns the error
"java.lang.ClassNotFoundException: org.postgresql.Driver". I'm at a bit
of a loss. Do I have to register the JDBC driver? If I do, how do I do
that? Could this be because the PostgreSQL daemon is running from a
different account than I am running the JDBC test application from? Did
I put the JDBC driver in the wrong directory?
Would really appreciate the help.
Thanks,
Craig Lawton

[JDBC] JDBC executeUpdate() does not return the number of rows effected
Hi all, I have been using the JDBC driver for a couple of months now. The only limitation I have run into for my own uses is that calling executeUpdate() does not return the number of rows effected by update or delete statement -- it always returns 0. Is this a limitation of Postgresql (i.e. the backend does not provide this info) or a limitation of the JDBC driver? If it is not a limitation of the backend, does anyone have an idea if this bug would be as easy to fix as it appears on the surface?

The jdbc driver does not support updateable result sets.

[JDBC] JDBC driver implementation
Hello, I have a situation where I just want the changes to be made temporarily in the ResultSet. I don't want to commit the changes to the database. When I use the ResultSet.updateString(...), ResultSet.updateBoolean(...), or ResultSet.updateObject(...) methods; I get the message "This method is not yet implemented." Looks like the implementation for the above methods has not yet been provided in version 7.1.2 I don't know if I am alone in this situation. Has anyone encountered such a problem? And how have you gotten around solving the it.The problem:- Being unable to update an updatable resultset in PostgreSQL 7.1.2ThanksDo You Yahoo!? Make a great connection at Yahoo! Personals.

I guess "fix" is slightly misleading. This patch implements
DatabaseMetaData.getExportedKeys() which was previously not implemented, and provides
a better implementation of DatabaseMetaData.getImportedKeys() which was previously
half-implemented.
The methods are identical for both jdbc1 and jdbc2 so that's why the diff is quite
large. Perhaps identical code should be put into a single class and have the code
which differs in jdbc1 and jdbc2 in subclasses?

:-) I have tested it but only with 7.1.3 at the moment. What I meant to say is please
:check in case something major has been changed in 7.2. Also if the queries I'm using
:can be optimized in any way that would be great.
At the moment a value for PK_NAME (primary key name) is not returned but the main part
is implemented.
Sorry for the lack of info, I'll try and be more helpful next time :)

Ned, It may or may not work. That file hasn't been changed in a long time, so I doubt anyone is using it and therefore it may no longer work. I don't want to give people the false impression that the javax.sql set of extensions to JDBC2 is supported by the jdbc driver by providing a jdbc7.2-1.2ee.jar file when we only implement 1 interface out of the 13 defined in that package. thanks, --Barry Ned Wolpert wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > Humm... are you saying that the class PostgresqlDataSource doesn't work?

Re: [JDBC] DatabaseMetaData.getImported/ExportedKeys() patch
Jason,
Can you explain what this patch is attempting to fix? Given that we are
in beta with 7.2, I want to fully understand the problem here before
applying this patch. (Especially given that the diff is pretty large and
not a one or two line change).
Also what testing have you done on this? (When you ask us to 'check
that it works', it doesn't give me a high level of confidence that this
is well tested).
thanks,

Re: [JDBC] j2ee compatiable jdbc driver on jdbc.postgresql.org?
Ned, There really isn't a j2ee driver for postgres. If you build the j2ee driver it is essentially the same as the j2se driver. So I don't see any reason to confuse people by letting them think there really is a difference by having two different java2 drivers to choose from on the web site. The only difference is some code that I consider questionable, and I don't think even works. thanks, --Barry Ned Wolpert wrote: > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > Folks- > > I checked out the jdbc driver for 7.2b1 on the jdbc.postgresql.org website > (http://jdbc.postgresql.org/download/jdbc7.2b1-1.2.jar) and I was going to > submit it for testing with the castor project.

[JDBC] Logging in the driver

Maybe you'll just have to force charset at connexion opening just like
this :
Connection conn =
DriverManager.getConnection("jdbc:postgresql://myDataBase?charSet=iso-8859-1",uid,pw);
You can force charSet to different values. There's a complete paragraph
on Postgresql doc on supported charsets.
Hope it would help.

Re: [JDBC] "No Suitable Driver"
You need to load the driver first and then get the connection, also the
url for the connection s/b
jdbc:postgresql://hostname/test&user=test&password=test"
Assuming your database name is test
So your code needs to execute
Class.forName("org.postgresql.Driver")
And then
Connection db =
DriverManager.getConnection("jdbc:postgresql://hostname/test"test",test"
);

That should work fine. I've been doing that since Ant version 1.3. Do you have
a specific case that doesn't work? (You can always specify absolute paths in
the properties, if you like...)

You can either set-it in the build.xml file via a property tag
or during the startup of ant using the -D flag. (set the ANT_OPTS var to
"-Dbuild.compiler=jikes" in your environment before running ant)

I know and I've used GNU Make when working with Windows, but that taught me that you often need alot more than GNU Make to port a makefile to Windows. Maybe maintaining two versions would be the best, ie. Make is used when building the distribution and Ant makefiles are provided for the convenience of users that think Ant works better.

Re: [JDBC] FW: Re: [PATCHES] Ant configuration
Tom, My reasons for not wanting to depend on Ant are: Many binary distributions of Postgres are not including the JDBC code because of the added overhead of the jdbc build process (i.e. getting Ant installed). Users have complained to the mail lists in the past about the requirement for Ant (they expect make; make install to work for jdbc just like it does for the rest of the postgres). (However I realize there are equally good arguments on why depending on Ant is a good thing.) Thus I thought a good compromise was to include the Ant libraries in postgres for building, however after seeing the size of them, I agree that is clearly not an option. Your rationale with regards to "since you require java to build, what is one more dependency" is a little flawed. The java dependency is both a build time and runtime dependency. In order to use the result of the build you need java so the expectation that you will have java if you are dealing with jdbc is high (otherwise why would you bother). However the dependency on Ant is only for building. The one thing this thread has made abundantly clear for me it that we are far from agreement on what the ideal solution is (and there probably isn't an ideal solution), thus I feel we should stick with status quo for 7.2 and deal with all of this in a few months after 7.2 is production. thanks, --Barry Tom Lane wrote: > Barry Lind <[EMAIL PROTECTED]> writes: > >>If we can include the ANT libraries in our CVS then my >>objection to ANT (requiring users to trackdown and download ANT) goes >>away, and I would then suggest we continue to use ANT for the other >>reasons you mention. >> > > The sheer bulk of the ANT libraries rules that out, even if there > weren't a management/synchronization issue: do you want a PG release to > be using an older ANT than what you have already installed locally? > > On the other hand, I can see no reason why we shouldn't say that you > *must* have ANT installed to build the JDBC driver.

Yes, but ant refused to recognize the srcdir as absolute and thinks it's
relative to the build dir. (Or at least it was something stupid like
that; it's been a while.)

Yeah, but how do you set the "build.compiler" property? This requires
pretty advanced knowledge.

Re: [JDBC] Ant installation (and other) issues!
Title: RE: [JDBC] Ant installation (and other) issues! Why is this such a big issue? Shipping the Ant binary would be like shipping the make binary, which seems silly to me. However, I would far prefer to use Ant to build the JDBC driver. So, is it not possible to simply maintain a Makefile.in, and a build.xml, and then people can specify --with-java-ant or --with-java-make on the configure command line? And if you specify --with-java without specifying a build tool, then it uses make. And the build.xml should be for the current production version of Ant, unless otherwise agreed by the developers for some or other good reason. At the end of the day, there are some versions of make which just won't build Postgres, because of some or other proprietary stuff, or because they are buggy, or whatever. Same goes for Ant. If you want to use Ant, you either use the latest production release, or you're on your own. What's the big deal? I'm sure there is at least one person in each 'camp' who is willing to maintain the Makefile.in or build.xml respectively. Isn't there?

[JDBC] JDBC issues for JDK1.4
Hi folks I'd like to make the JDBC driver comple with JDK1.4. I've got the following list of errors and potential remedies. Does anyone have any objections if I start work on this? The following are the methods defined in JDK1.4 which are not currently implemented in the JDBC driver: javax.transaction.RollbackException is not defined in 1.4. -- this appears to be renamed to TransationRolledbackException Statement.getMoreResults(int) -- defines the behaviour of the current ResultSet when the next one is retrieved. Appears that we need to simply perform appropriate operations on the result instance field of jdbc2.Statement. PreparedStatement.setURL(java.net.URL) -- Presumably convert the URL to a string and set it like everything else? CallableStatement.registerOutParameter(String, int) -- There are a bunch of these actually, javac is only listing one. They all take parameter names rather than indexes. Should be straightforward to fix? Connection.setHoldability(int) -- Not too sure about this. It defines the "holdability" of result sets between commits. Need to investigate further (tips?) DataBaseMetaData.supportsSavepoints() -- Presumably: "return false;" ResultSet.getURL(int) -- Presumably, "return new URL(getParameter...));" PGblob.setBytes(long, byte[]) PGclob.setString(long, String) -- This stuff looks harder, there are setBinaryStream() etc methods. Not sure how to go about this at this stage. Maybe an Unsupported exception? ClientConnection.setHoldability(int) -- presumably, pass the call to Connection.setHoldability()?

[JDBC] Compliance? Plans?
Hi again all, First off, I´d like to declare that my intention is not to be a pain in the B** :-) Working on customer´s campuses equipped with laptop and a viennaSQL (a pure java sql client) i have had the need for many different drivers for different dbmses. The effort involved getting a working jdbc driver for the dbms at hand has varied; from extremely easy to almost impossible. As I´m currently promoting postgreSQL as an Orcacle alternative, I have been working in parallell with both drivers and the driver´s compliance to the api differs, which has really been a hazzle. My questions to the people actively developing the driver is: 1. How is the driver compliance tests carried out? The test harness from sun? 2. How often is compliance tests carried out? 3. Is there a policy for those issues where postgres has limited backend support for the jdbc API functions? 4. Is there a development plan for the jdbc package, similar to that of the server itself? lastly, while I´m at it :-) Is there a known problem with the implementation of java.sql.Blob.getBinaryStream() implmentation? I get the size of the blob with length() and its correct While reading the Stream I get returncode -1 immediatly server is 7.1.3 jdbc built on jdk 1.3 on linux. Same error appears on win2000 (using the same driver) Regards, Per-Olof Norén Stockholm, Sweden

The sheer bulk of the ANT libraries rules that out, even if there weren't a management/synchronization issue: do you want a PG release to be using an older ANT than what you have already installed locally? On the other hand, I can see no reason why we shouldn't say that you *must* have ANT installed to build the JDBC driver. You've gotta have Java to build JDBC, no? Seems like ANT is just one more dependency, and hardly an unreasonable one if it's the standard for Java projects.

Would someone want to build the JDBC driver without building the rest of postgresql? If this is the case, then we need to make sure that we provide the tools needed build the JDBC driver in this type of environment. If this is not the case, then it doesn't/shouldn't matter, since the build is directly linked to postgresql. Let me ask people this question: Do we support building of the JDBC driver externally to building postgresql? Or, do we 'ship' or otherwise make available the various JDBC driver in pre-build jar/binaries? Up to this point, people have basically been expected to get the latest JDBC driver from CVS and re-build it. If this is expected to continue, I recomend making the JDBC driver easy to build outside of the postgresql project. However, if the releases will start to contain all the fixes from 7.2 and beyond, then it doesn't matter to non-postgresql developers as much. (It may still matter, but its less of a big deal.) (Personally, I love Ant as a development tool. But the quality of Ant isn't the issue here, its ease of development. Multiple build-tools can create confusion. If 'from now on', we don't expect individuals to build the JDBC driver on their own, but use binaries, than simplfying the build procedure by only using make should be fine.)

Here is updated patch:
* fixed couple of typos.
* installdirs and uninstall targets
* converted contrib/retep to make too, now no parts
of PostgreSQL source _require_ Ant.
* made the JUnit tests work too

This seems to be Ant-based build process. * What the PostgreSQL core developers find themselves comfortable with. This means keeping the overall PostgreSQL build process complexity down and making the general './configure;make;make install' as smooth as possible. As the rest of the PostgreSQL uses make, it would be simpler for them to use make for Java too. * Special case: general UN*X system, Java but no Ant. How probable this is? User probably wants to compile all of PostgreSQL distribution. One solution is to include Ant .jars in PostgreSQL source. * Special case: non-Unix system, Unix tools are hard to use, Ant is easier. How probable this is? User is hacking only JDBC. I sent a patch earlier which solves the above problems by using both Ant and make to compile JDBC: when driver is compiled with rest of the PostgreSQL, the build is make-only, but it also makes Ant-only build possible by preparing ant.cfg file with configure variables. But this has new problem: now two build systems must be maintained. Whether this is acceptable depends on how complex they are and how often they must be modified. I tried to keep the make variant as simple as possible: no dependencies need to be tracked specially, only few special files are mentioned explicitly. On what direction to take the final word must be said by JDBC developers, as they are most affected by it. -- marko ---(end of broadcast)--- TIP 4: Don't 'kill -9' the postmaster

Thank you very much. ;-) I can't your point or the joke, please enlighten me ;-) make is AFAIK the most common build program, but that doesn't mean that the tool is ideal everywhere. Progress is possible you know, evolutionary or revolutionary. GNU Make has been evolutionary, Ant is revolutionary. configure management is certainly a lot more than configure. I would argue that CVS is the most important configuration management tool, but the issue is of course broader. But anyway this off topic, what need to have is a build process that works nicely and I think including the ant binaries(around 500k) would be the best solution here. -- Gunnar Rønning - [EMAIL PROTECTED] Senior Consultant, Polygnosis AS, http://www.polygnosis.com/ ---(end of broadcast)--- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]

If we were, I could see a stronger argument for Ant. As it is now, we have to weigh using a Java-standard Ant vs. a PostgreSQL/C-standard makefile solution. -- Bruce Momjian| http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup.| Drexel Hill, Pennsylvania 19026 ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org

Some people see Ant as problematic because it isn't the standard build tool used for Postgres. Others see make as problematic because it isn't a standard for building java applications (although I know of as many java apps built with make as with Ant personally). But the jdbc driver for postgres is both a postgres component and in java. thanks, --Barry ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
