This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
Hi I have a situation where I need to look up data from different databases.This is the case : I have data on Oracle and also data on Informix. I have entire access to the data on Oracle but not on the other. The only thing I can do is read data. How do I frame my query to retrieve data. Can some help me. Please give it to me as a sequence of steps Thanks Suneel
Hi Thomas Thanks for the answer. But I think I must also add that I don't have a common field to link the 2 databases. What I wanted to know was that do I need to create a relation table and then frame a query. If I do need to, how do I go about it? Thanks Suneel
Ashish: as of the latest release of jdbc(not including the jdk 1.4 beta) you can only have one connection per statement/prepared statement. So you can not do this in java as you would need two different connections if you were to join 2 tables from different databases in one statement. You can have 2 different connections open at the same time, but you can only have 1 connection for a statement. Jamie

Ashish & Jamie, Db2 UDB has a function called federated databe support. This lets a DB2 server 'front' two or more different databases so that an application can use only one connection (to the DB2 server) and actually access two other databases. /Anders
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
