Thread: JDBC Support - prepared Statements?

JDBC Support - prepared Statements?

From
Mariano Kamp
Date:
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 ;-)

I would get the newest Jdbc from:
http://jdbc.fastcrypt.com

It has more bug fixes than 7.1.X.

Hm, I build everything from source. Perhaps the RPM is buggy.

Did you try the latest 7.1.2 release? I did so recently and did not
encounter any problems with PreparedStatements. (There are still other bugs in the
JDBC driver, but that's another story.)

I would get the JAR from:
http://jdbc.fastcrypt.com

This is a copy of the CVS tree, which has some bugs fixed from 7.1.2.
