insufficient privilege for SQL PREPARE statement

I am using the below statement on the hanatrial.ondemand.com account in an .xsjs script:

pStmt = conn.prepareStatement('insert into "<account>.<package>:Person"("oid", "history.createdAt",  "history.createdBy","name", "firstName" ) values (?, now(), ?, now(), ?, ?, ?)');

  pStmt.setInteger(1,personOid);  // object id

  pStmt.setString(2,user);

  pStmt.setString(3,user);

  pStmt.setString(4,name);

  pStmt.setString(5,firstname);

  pStmt.execute();

  conn.commit();

as a result I am getting the error:

InternalError: dberror(Connection.prepareStatement): 258 - insufficient privilege: Not authorized at ptime/query/checker/query_check.cc:2422 (line 277 position 0....

how can I set the authorization to execute a prepare statement?
