[GENERAL] fun in redmond
Microsoft adds Java support to database Microsoft is planning to make available software for linking Java programs to its database software. The Redmond, Wash., behemoth said Tuesday that it will sell software that allows Java programs to connect to data housed in Microsoft's SQL Server 2000 database. Microsoft is licensing the software, called a Java Database Connectivity (JDBC) driver, from software maker Merant and re-branding it under the Microsoft name. Isn't that a laugh. Microsoft supporting a non standard connection method... I thought that asp was a nice secure protocol for connecting web applications to SQL server =:-D Cheers Tony Grant ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send unregister YourEmailAddressHere to [EMAIL PROTECTED])

Nor do I believe these claims, btw. Has anyone done any measurements of performance with/without these options? I know I haven't.

[GENERAL] Fastest way to load data in a table
Hi all. I need to clean and fill periodically a database with several hundred thousands records readed from a plain ascii file. I have a Python script that opens the file and then, after a 'DELETE * FROM table' submits an INSERT for each registry, but this process is very slow. How can I accelerate this uploading process ?

Re: [GENERAL] fun in redmond
What was wrong with JDBC::ODBC? I don't use Java, but I thought this solution was out there for a while already? Just not db-specific enough for them? tony [EMAIL PROTECTED] on 09/26/2001 04:09:32 AM To: postgres list [EMAIL PROTECTED] cc:(bcc: Wesley Sheldahl/Lex/Lexmark) Subject: [GENERAL] fun in redmond Microsoft adds Java support to database Microsoft is planning to make available software for linking Java programs to its database software.

Re: [GENERAL] postgresql.conf
Thank you very much. Actually, it was the optimization parameters that I was interested in. My db works rather slow even in single user mode and I wondered if I had missed some setup. BTW, is there a way to see what parameters are in effect? -Original Message- From: Lamar Owen [EMAIL PROTECTED] To: Mihai Gheorghiu [EMAIL PROTECTED]; [EMAIL PROTECTED] [EMAIL PROTECTED] Date: Tuesday, September 25, 2001 8:30 PM Subject: Re: [GENERAL] postgresql.conf On Tuesday 25 September 2001 11:34 am, Mihai Gheorghiu wrote: I installed PG from RPMs. postgresql.conf comes with all options commented out.

Re: [GENERAL] JDBC update wont, plz help.
Vic,
Can you post the errors you are getting for both the build problem and
the runtime problem you originally reported?
Without the exact errors you are getting, I can only guess at the
problems you are encountering. But my guess as to your original problem
is that your code is trying to use updateable result sets which the
driver does not support.
I wouldn't bother trying to build the EE version of the driver. It
doesn't have very much additional functionality (it only impliments a
small subset of javax.sql), and I doubt that is the source of your
original problem.
thanks,
--Barry

Is there someone who can make a build with sqlX java (must have J2EE SDK
enviroment) ?
Help.. please
