String query = "select * from cdr where phone_number=? AND day_of_year between 291 AND 292 " ; PreparedStatement stmt = conn.prepareStatement(query); stmt.clearParameters(); stmt.setString(1,"+552192223293"); ResultSet rs = stmt.executeQuery();
/* String query = "select * from cdr where phone_number='+552192223293' AND day_of_year between 291 AND 292" ; Statement stmt = conn.createStatement(); ResultSet rs = stmt.executeQuery(query); */ if(rs.next()) System.out.println("Successful"); else System.out.println("Unsuccessful"); rs.close(); stmt.close(); conn.close(); } } When I Comment the Prepared Statement and use normal Statement the query comes out very fast however When I use Prepared Satement it just hangs .
The Load in the Table is around 2000 million. and the Phone number is indexed. and day_of_year is partitioned.
Any help is appriciated as to why Prepared Staement is hanging.
Thanks in Advance

You have a table with 2 billion entries? Impressive.
Can you run an analyzer to see what plan is actually executed? Maybe the index is disregarded for some reason, and a table scan would take some time for such a big table. [ November 07, 2005: Message edited by: Ulf Dittmer ]
