# CallableStatements and OUT Parameters

Derby supports OUT parameters and CALL statements that return values, as in the following example:

    CallableStatement cs = conn.prepareCall(
       "? = CALL getDriverType(cast (? as INT))"
    cs.registerOutParameter(1, Types.INTEGER);
    cs.setInt(2, 35);
    cs.executeUpdate();

Note: Using a CALL statement with a procedure that returns a value is only supported with the ? = syntax.

Register the output type of the parameter before executing the call.
