我们的系统非常庞大，架构中有大约100多个表。有一个业务要求，我们决定在存储过程中处理它。在我们的应用程序中，我们也有java，但我们选择使用存储过程。为了满足要求创造3个功能。 这些函数是SQL查询的一部分，它被触发以获取计数和显示记录。现在我们在连接中设置SQL超时，设置为60秒。 当我们对40K的记录运行此查询时，操作会超时并且我们不会得到任何结果。 我在这里粘贴所有这三个函数的实际实现，下面是查询谁利用所有这些创建的函数。
在下面的查询中，标记了以粗体字母调用的函数。
我正在查看您的专家建议，通过该建议，我可以调整此实现以处理100K数据。 我们有oracle 11gR1 ..即使这个实现也是在Ajax调用中从web访问。
如果您还有其他需要，请告诉我。
