                 Key: DERBY-3125
                 URL: https://issues.apache.org/jira/browse/DERBY-3125
             Project: Derby
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 10.4.0.0
            Reporter: Kathey Marsden
            Priority: Minor


Running the following program with either embedded or client does not adjust 
the scale of the output parameter.


public class DecimalOutParam {

    public static void main(String[] args) throws Exception
    {
        //Class.forName("org.apache.derby.jdbc.ClientDriver").newInstance();
        //Connection conn = 
DriverManager.getConnection("jdbc:derby://localhost:1527/wombat;create=true");
        Class.forName("org.apache.derby.jdbc.EmbeddedDriver").newInstance();
        Connection conn = 
DriverManager.getConnection("jdbc:derby:wombat;create=true");
        Statement s = conn.createStatement();
        try 
            {
            s.executeUpdate("DROP PROCEDURE DECPROC");
            } 
        catch (SQLException se)
            {
                
            }
        s.executeUpdate("CREATE PROCEDURE DECPROC(OUT DECIMAL(10,2))  parameter 
style java language java NO SQL external name 'DecimalOutParam.decProc'");
        
        CallableStatement cs = conn.prepareCall("CALL DECPROC(?)");
    cs.registerOutParameter(1,java.sql.Types.DECIMAL, 0);
    cs.executeUpdate();
    System.out.println(cs.getBigDecimal(1));    
       

    }


    public static void decProc(BigDecimal [] outDec)
    {
        outDec[0] = new BigDecimal("123.45");

    }
}
