Daniel John Debrunner commented on DERBY-3125:
----------------------------------------------
It would be good to get some clarification on what the scale set by
registerOutParameter should affect. E.g.
- should decimal digits be modified on a setBigDecimal for INOUT parameters ?
- should parameter meta data reflect the scale of the declared parameter of
the procedure or of the scale set by registerOutParameter?
- how does getBigDecimal() that takes a scale value behave?
> registerOutputParameter with a specified scale does not adjust the scale of
> the output parameter

> 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");
