解决500行限制

我已经写了一个Google Fusion Tables脚本，我很满意（下面），但它只加载了500行，我的表中有超过20000行。这是我第一次在这附近，我真的很惊讶地发现这个限制。有没有办法加载所有的行？解决500行限制

我使用json调用方法解决了这个问题。下面的代码。

辉煌。只是我希望的线索。能够为我的测试案例做这项工作。 ChartTools API处理将FT响应对象转换为DataTable的许多便利，但应用500行限制。直接使用Ajax允许人们绕过这个限制，而且还能直接处理它返回的底层数据结构。 – prototype

Gviz API确实对给定查询有500行限制。

任何表限制为100,000 可映射行，但这远远超出您报告的20,000行。

当前接受可信测试人员的新JavaScript API为查询返回的任意数量的行提供了JSON格式支持。您可以通过此组中的成员资格申请办理的TT程序： https://groups.google.com/group/fusion-tables-api-trusted-testers

我经常通过删除所有行和插入新的刷新2500行的表。我的代码中构建INSERT sql的循环有一个嵌套的循环，数量为400，发送该sql，然后开始构建另一个与下一个400记录。
