在不依赖Oracle的Java中使用Oracle ref游标 [英] Using Oracle ref cursor in Java without Oracle dependency

问题描述

根据Google和其他一些来源(例如， http://www.enterprisedt. com/publications/oracle/result_set.html )，如果我想调用一个返回引用游标的存储函数，则需要编写如下代码才能访问ResultSet:

According to google and some other sources (e.g., http://www.enterprisedt.com/publications/oracle/result_set.html), if I want to call a stored-function that returns a ref cursor, I need to write something like this in order to access the ResultSet:

String query = "begin ? := sp_get_stocks(?); end;";
CallableStatement stmt = conn.prepareCall(query);
// register the type of the out param - an Oracle specific type
stmt.registerOutParameter(1, OracleTypes.CURSOR);
// set the in param
stmt.setFloat(2, price);
// execute and retrieve the result set
stmt.execute();
ResultSet rs = (ResultSet)stmt.getObject(1);

在没有引入对Oracle的编译时依赖性的情况下，仍然可以做到这一点.是否有OracleTypes.CURSOR的通用替代方法?

Is there anyway to do it without introducing the compile-time dependency on Oracle. Is there a generic alternative to OracleTypes.CURSOR?

推荐答案

常量OracleTypes.CURSOR为-10.很丑陋的解决方案，但是您可以在那里写-10或创建自己的值为-10的常量.

Constant OracleTypes.CURSOR is -10. Quite ugly solution but you can just write -10 there or create your own constant which value is -10.
