-/*                    COMPILE TIME SANITY CHECKS                    */
-/* ================================================================ */
-
-/*
- * NOTE 1:
- * -------
- *
- * All checks done in this file are intentionally placed in a public
- * header file which is pulled by curl/curl.h when an application is
- * being built using an already built libcurl library. Additionally
- * this file is also included and used when building the library.
- *
- * If compilation fails on this file it is certainly sure that the
- * problem is elsewhere. It could be a problem in the curlbuild.h
- * header file, or simply that you are using different compilation
- * settings than those used to build the library.
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * curl library user nor by the curl library builder.
- *
- * Do not deactivate any check, these are done to make sure that the
- * library is properly built and used.
- *
- * You can find further help on the libcurl development mailing list:
- * http://cool.haxx.se/mailman/listinfo/curl-library/
- *
- * NOTE 2
- * ------
- *
- * Some of the following compile time checks are based on the fact
- * that the dimension of a constant array can not be a negative one.
- * In this way if the compile time verification fails, the compilation
- * will fail issuing an error. The error description wording is compiler
- * dependent but it will be quite similar to one of the following:
- *
- *   "negative subscript or subscript is too large"
- *   "array must have at least one element"
- *   "-1 is an illegal array size"
- *   "size of array is negative"
- *
- * If you are building an application which tries to use an already
- * built libcurl library and you are getting this kind of errors on
- * this file, it is a clear indication that there is a mismatch between
- * how the library was built and how you are trying to use it for your
- * application. Your already compiled or binary library provider is the
- * only one who can give you the details you need to properly use it.

- * Verify that some macros are actually defined.

 TDengine 采用 SQL 作为查询语言。应用程序可以通过 C/C++, Java, Go, Python 连接器发送 SQL 语句，用户可以通过 TDengine 提供的命令行（Command Line Interface, CLI）工具 TAOS Shell 手动执行 SQL 即席查询（Ad-Hoc Query）。TDengine 支持如下查询功能：

 为满足物联网场景的需求，TDengine支持几个特殊的函数，比如twa(时间加权平均)，spread (最大值与最小值的差)，last_row(最后一条记录)等，更多与物联网场景相关的函数将添加进来。TDengine还支持连续查询。

-## 多表聚合查询
 物联网场景中，往往同一个类型的数据采集点有多个。TDengine采用超级表(STable)的概念来描述某一个类型的数据采集点，一张普通的表来描述一个具体的数据采集点。同时TDengine使用标签来描述数据采集点的静态属性，一个具体的数据采集点有具体的标签值。通过指定标签的过滤条件，TDengine提供了一高效的方法将超级表(某一类型的数据采集点)所属的子表进行聚合查询。对普通表的聚合函数以及绝大部分操作都适用于超级表，语法完全一样。

 物联网场景里，经常需要通过降采样（down sampling）将采集的数据按时间段进行聚合。TDengine 提供了一个简便的关键词 interval 让按照时间窗口的查询操作变得极为简单。比如，将智能电表 d1001 采集的电流值每10秒钟求和

 物联网场景里，每个数据采集点采集数据的时间是难同步的，但很多分析算法(比如FFT)需要把采集的数据严格按照时间等间隔的对齐，在很多系统里，需要应用自己写程序来处理，但使用TDengine的降采样操作就轻松解决。如果一个时间间隔里，没有采集的数据，TDengine还提供插值计算的功能。
