包頭:
create or replace package pack_test1 is
? type userClass is ref cursor;
? procedure pro_test1(pkCorp in varchar2,userList out userClass);
end pack_test1;
包體:
create or replace package body pack_test1 is
? -- Function and procedure implementations
procedure pro_test1(pkCorp in varchar2,userList out userClass) is
? begin
?? open userList for SELECT * FROM rp_user? where corpcode in pkCorp;
? end;

end pack_test1;
Java代碼:
DBConnection DBConn = new DBConnection();
Connection Conn = DBConn.getConn();
ResultSet rs = null;
String sql = "call pack_test1.pro_test1(?,?)";
CallableStatement call = Conn.prepareCall(sql);
//輸入參數賦值
call.setString(1, pk_corps);
//申明輸出參數
call.registerOutParameter(2, OracleTypes.CURSOR);

//執行
call.execute();
//取出結果
? rs = ((oracle.jdbc.OracleCallableStatement)call).getCursor(2);
while(rs.next()){
UserVo userVo = new UserVo();
userVo.setUnitname(rs.getString("username"));
userVo.setRealname(rs.getString("realname"));
list.add(userVo);

}
不報錯，但是結果集沒有數據，我確定我表里面是有數據的，麻煩老師幫我看看吧，哪里出錯了呀！
