Mysql CFloop处理非常慢
我在自学CF开发，并在学习过程中使用共享的CF托管站点进行测试 我有一个电子表格，包含2500多条数据记录，大约15列。电子表格包含对该应用程序的基础至关重要的数据。它保持脱机状态，并使用cffile定期上载到服务器。上传后，电子表格逐行导入到MySQL表中 问题是它花的时间太长了。例如，它目前正在运行。在过去43分钟内，2500条记录中只有192条被添加到MySQL表中。有没有更有效的方法 如果您查看下面的代码，在cfloop内部，它将运行cfspreadsheet标记，并检索当前行。然后将该行作为CSV数据添加到MySQL表中 关于如何更有效地做到这一点，有什么建议吗Mysql CFloop处理非常慢,mysql,coldfusion-9,cfloop,cfspreadsheet,Mysql,Coldfusion 9,Cfloop,Cfspreadsheet,我在自学CF开发，并在学习过程中使用共享的CF托管站点进行测试 我有一个电子表格，包含2500多条数据记录，大约15列。电子表格包含对该应用程序的基础至关重要的数据。它保持脱机状态，并使用cffile定期上载到服务器。上传后，电子表格逐行导入到MySQL表中 问题是它花的时间太长了。例如，它目前正在运行。在过去43分钟内，2500条记录中只有192条被添加到MySQL表中。有没有更有效的方法 如果您查看下面的代码，在cfloop内部，它将运行cfspreadsheet标记，并检索当前行。然后将该
每次迭代都要读取整个XLS文件，只是为了获取一行。只需在循环之前读取一次文件，然后在其行上循环。Yes'r试图找到一种方法来防止每次循环都打开电子表格，这就解决了它。。。现在快多了

关键的应用程序的基础，然后你可以考虑使用不同的方法，因为上面它易碎。使用加载数据插入工作表将更快，并提供对导入过程的更好控制。另外，请始终将cfqueryparam与查询参数一起使用。除了防止sql注入之外，它还有助于在多次执行同一查询时提高性能？存储分隔数据几乎从来都不是一个好方法。
