[PERFORM] effizient query with jdbc

[Bühler , Johannes]

Hi,
I have a java.util.List of values (1) which i wanted to use for a query in 
the where clause of an simple select statement. iterating over the list and and 
use an prepared Statement is quite slow. Is there a more efficient way to 
execute such a query.
Thanks for any help.

.
 
List ids = new ArrayList(); 

 List is filled with 1 values ...

List uuids = new ArrayList();
 
PreparedStatement pstat = db.prepareStatement("SELECT UUID FROM 
MDM.KEYWORDS_INFO WHERE KEYWORDS_ID = ?");
 
for (Iterator iter = ids.iterator(); iter.hasNext();) {
   String id = (String) iter.next();
   pstat.setString(1, id);
   rs = pstat.executeQuery();
 if (rs.next()) {
uuids.add(rs.getString(1));
   }
   rs.close();
  }
...
