performance - How do you adjust Sybase optimizer settings in Java at the session level? -
per sybase, can adjust optimizer settings @ session level such:
set plan optgoal allrows_dss
but syntax use include in connection string using java's drivermanager.getconnection? right this:
connection conn = drivermanager.getconnection("jdbc:sybase:tds:myservername:myportnum/mydbname", user, password);
thanks in advance answers.
ok, figured out, sharing wants know in future. don't know if right or best way, works:
connection conn = drivermanager.getconnection(url, user, password); statement s = conn.createstatement().executeupdate(" set plan optgoal allrows_oltp "); resultset rs = conn.createstatement().executequery(" select @@optgoal "); rs.next(); system.out.println("session-level optimizer set to: " + rs.getstring(1));
