Hi Tom,
I'm also having problems with fecthing and moving backwards within a view.
ie. (comparison_region_protein is a view)
int result = stmt.executeUpdate("declare test cursor for select id from " +
"comparison_region_protein where db_db_comparison =
1 order by id");
I can move and fetch forward, but i can't fetch or move backwards. Is
this because of the reasons metioned before? Is there a work around?
Many thanks
Noel
