I have searched the archives and tried two different approaches, both are giving me errors.
(Calling a stored function that returns e.g. an Integer works fine).
Could this be because I'm running PG 7.3.2 ? Would an upgrade to 7.3.4 help?
aa_test is a stored function that takes an integer and returns a refcursor. aa_test works as expected when run from pgsql command line.
Approach #1:
PreparedStatement ps = dbConn.prepareStatement("select aa_test(1)");
ResultSet rs = ps.executeQuery();
while (rs.next())
{
System.out.println("Got : " + rs.getString(2));
// or System.out.println(rs.getString("rpu_name"));
}
rs.close();
ps.close();
Gives the run-time error:
"The column index is out of range"
Approach #2:
CallableStatement cs = dbConn.prepareCall("{? = call aa_test(?) }");
cs.registerOutParameter(1,Types.OTHER);
cs.setInt(2,27);
try
{
cs.execute();
ResultSet rs = (ResultSet) cs.getObject(1);
while (rs.next())
{
System.out.println(rs.getString("rpu_name"));
}
}
catch (java.sql.SQLException ex)
{
System.out.println("test function exception :" + ex);
}
rs.close();
cs.close();
Gives the run-time error "No class found for refcursor"
