Обсуждение: JDBC Support - prepared Statements?
Hi there, we are developing reporting software and want to support at least one open source alternative to oracle. Things were going very smoothly with postgresql and the only problem we are facing is the I get an exception stating that with the current jdbc driver prepared statements are not supported (yet). Are there any plans, probably even kind of time frames, when to support prepared statements? Even if postgresql wouldn't support preparing the statement it would be nice if it would at least fake it, so that the API can be used. We are relying on a third party component, which just can do prepared statements. Thanks, Mariano
Hello Rainer, yes I did so. The name of the rpm I recently downloaded is: postgresql-jdbc-7.1.2-4PGDG.i386.rpm and it is throwing the exception when calling the prepareStatement() Method. But when I get back some air to breathe I will go and double-double-check that my classpath is setup properly ;-) Mariano On Tuesday 03 July 2001 10:02 am, Rainer Klute wrote: > > ... and the only problem we are facing is the I get an exception stating > > that > > > with the current jdbc driver prepared statements are not supported (yet). > > Did you try the latest 7.1.2 release?

I would get the newest Jdbc from: http://jdbc.fastcrypt.com It has more bug fixes than 7.1.X. > Hello Rainer, > > yes I did so.

Hm, I build everything from source. Perhaps the RPM is buggy. -- Best regards Rainer Klute Dipl.-Inform.

<p><font size="2">The release postgresql-jdbc-7.1.2-4PGDG.i386.rpm is definately buggy. Or at least there has been a confusionwith versioning. I have a had a number of small issues, but when I downloaded the source and compiled the JDBC driversthrough ANT they worked fine.</font><p><font size="2">addBatch() and executeBatch() should work also in the RPM butthey throw "method not yet implemented errors"...</font><p><font size="2">jon folland</font><p><font size="2">head oftechnology</font><br /><font size="2">_ tripledash /</font><p><font size="2">phone +44 020 7377 07 75</font><br /><fontsize="2">fax +44 020 7247 69 30</font><br /><font size="2">mobile +44 07974 324 260</font><p><font size="2">www.tripledash.co.uk</font><br /><br /><p><font size="2">-----Original Message-----</font><br /><font size="2">From:Bruce Momjian [<a href="mailto:pgman@candle.pha.pa.us">mailto:pgman@candle.pha.pa.us</a>]</font><br /><fontsize="2">Sent: 10 July 2001 22:21</font><br /><font size="2">To: Rainer Klute</font><br /><font size="2">Cc: MarianoKamp; pgsql-hackers@postgresql.org</font><br /><font size="2">Subject: Re: [HACKERS] JDBC Support - prepared Statements?</font><br/><p><font size="2">> > yes I did so.
