Dear All,

I use hibernate 2.1.6 and the datasource is csv(use to test import data and not export data to datasource);

when linking the datasource there is no problem.

however,there are some errors in getting data:

help me pls,thanks!

your jdbc driver does not implement enough of the jdbc API to allow hibernate to query for it's state.

Go back to whoever wrote org.relique.jdbc.csv driver and say they should support setAutoCommit/getAutoCommit.

thanks ,I'll have a try
