JDBC - varchar or nvarchar fields?

Posted by D. on 05/09/06 18:40

Hi, I'm starting a new application in java using JTDS jdbc driver
(http://jtds.sourceforge.net) and SQLServer 2005 Express.
I have to design the database from scratch and my doubt is if I have to use
varchar or nvarchar fields to store string data.

Any experience about performance issues using nvarchar instead of varchar
(considering that Java internally works in unicode too)?

Thanks in advance,
Davide.
