我想要计算在Oracle BBDD上返回函数的行数。我在其他一些问题中看到过（例如：rs.last() gives Invalid operation for forward only resultset : last），需要添加ResultSet.TYPE_SCROLL_INSENSITIVE，ResultSet.CONCUR_READ_ONLY到可调用语句。resultset.last（）在java中抛出一个异常
我已经试过ResultSet.TYPE_SCROLL_INSENSITIVE，也ResultSet.TYPE_SCROLL_SENSITIVE ...没有结果。我仍然得到相同的无效操作异常。
我失踪了什么？
继承人我的代码：
String call = "{ ? = call MyProcedure (?) }";
CallableStatement cstmt= conn.prepareCall(call, ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
cstmt.setString(2,"param 1");
cstmt.registerOutParameter(1, OracleTypes.CURSOR);
cstmt.execute();
ResultSet rset = (ResultSet)cstmt.getObject(1);
rset.last(); //Exception comes here
int rowsnumber = rset.getRow();
感谢。
编辑：
正如评论说，我第一次添加了Oracle功能我打电话：
create or replace FUNCTION MyProcedure
(IdC IN VARCHAR2
)
RETURN sys_refcursor
IS
c_result sys_refcursor;
BEGIN
OPEN c_result FOR SELECT name, properties FROM city WHERE name = IdC;
RETURN c_result;
END;
