Return ROWID Parameter from insert statement using JDBC connection to oracle

Question

I can\'t seem to get the right magic combination to make this work:

OracleDataSource ods = new oracle.jdbc.pool.OracleDataSource();
ods.setURL(\"jdbc:oracle

A few things you'll need to do

• Change CallableStatement to OracleCallableStatement
• Try and return into a NUMBER, ie: OracleTypes.Number

Sample code for returning info from a query:

OraclePreparedStatement pstmt = (OraclePreparedStatement)conn.prepareStatement(
       "delete from tab1 where age < ? returning name into ?");
pstmt.setInt(1,18);

/** register returned parameter
  * in this case the maximum size of name is 100 chars
  */
pstmt.registerReturnParameter(2, OracleTypes.VARCHAR, 100);

// process the DML returning statement
count = pstmt.executeUpdate();
if (count>0)
{
  ResultSet rset = pstmt.getReturnResultSet(); //rest is not null and not empty
  while(rset.next())
  {
    String name = rset.getString(1);
    ...
  }
}
