Question

我已经完成了代码，它在scala中执行任何查询都是完美的，除非我的查询必须使用两次相同的参数。数据库版本是12，oracle jar是ojdbc6，我写这段代码才能执行查询

def executeQuery(locale: String, query: String, input: Map[String, String], output: List[String]): Vector[Map[String, Any]] = {
    var connection: Connection = null;
    val properties = ConnectionLoader.getConnectionProperties(locale);
    try {
      connection = getDBConnection(properties);
      val statement = connection prepareCall (query)
      if (null != input)
        for ((k, v) <- input) {
          statement.setObject(k, v)
        }

      for (k <- output) {
        statement.registerOutParameter(k, OracleTypes.INTEGER)
      }
      val resultSet = statement.executeQuery();


      realize(resultSet);
    } catch {
      case e => throw e;
    } finally {
      if (null != connection)
        connection.close();
    }
  }

我的查询是

SELECT COUNT (1) 
  FROM ORDERS
 WHERE ORDER_ID = :P_ORDER_ID  AND STATUS_ID = 4

这个查询工作正常，但我在执行时遇到错误

SELECT COUNT (1)
  FROM ORDERS
 WHERE ORDER_ID = :P_ORDER_ID  AND STATUS_ID = 4 and :P_ORDER_ID=9

无论这个非逻辑查询我都会收到此错误

执行异常[[SQLException：在索引:: 2处缺少IN或OUT参数]] 我已经搜索了所有内容，但我没有结果请建议

如何在scala中绑定oracle params？
