The string value should be quoted with single quotes. Literal single quote inside the string must be preceded with backslash, like `\'`. The length must be specified when defining a column or tag of NCHAR type, for example nchar(10) means it can store at most 10 characters of nchar type and will consume fixed storage of 40 bytes.

##### Use of TaosResult class
In the above example of using the `TaosConnection` class, we have shown two ways to get the result of a query: `fetch_all()` and `fetch_all_into_dict()`. In addition, `TaosResult` also provides methods to iterate through the result set by rows (`rows_iter`) or by data blocks (`blocks_iter`). Using these two methods will be more efficient in scenarios where the query has a large amount of data.

查询结果只能获取一次。比如上面的示例中 `fetch_all()` 和 `fetch_all_into_dict()` 只能用一个。重复获取得到的结果为空列表。

##### TaosResult 类的使用
上面 `TaosConnection` 类的使用示例中，我们已经展示了两种获取查询结果的方法： `fetch_all()` 和 `fetch_all_into_dict()`。除此之外 `TaosResult` 还提供了按行迭代(`rows_iter`)或按数据块迭代(`blocks_iter`)结果集的方法。在查询数据量较大的场景，使用这两个方法会更高效。

该提示是创建 db 的 vnode 数量不够了，需要的 vnode 不能超过了 dnode 中 vnode 的上限。因为系统默认是一个 dnode 中有 CPU 核数两倍的 vnode，也可以通过配置文件中的参数 supportVnodes 控制。
正常调大 taos.cfg 中 supportVnodes 参数即可。
### 21 在服务器上的使用 taos-CLI 能查到指定时间段的数据，但在客户端机器上查不到？
这种情况是因为客户端与服务器上设置的时区不一致导致的，调整客户端与服务器的时区一致即可解决。
### 22 表名确认是存在的，但在写入或查询时返回表名不存在，什么原因？
TDengine 中的所有名称，包括数据库名、表名等都是区分大小写的，如果这些名称在程序或 taos-CLI 中没有使用反引号（`）括起来使用，即使你输入的是大写的，引擎也会转化成小写来使用，如果名称前后加上了反引号，引擎就不会再转化成小写，会保持原样来使用。
### 23 在 taos-CLI 中查询，字段内容不能完全显示出来怎么办？
可以使用 \G 参数来竖式显示，如 show databases\G; （为了输入方便，在"\"后加 TAB 键，会自动补全后面的内容）
### 24 使用 taosBenchmark 测试工具写入数据查询很快，为什么我写入的数据查询非常慢？
TDengine 在写入数据时如果有很严重的乱序写入问题，会严重影响查询性能，所以需要在写入前解决乱序的问题。如果业务是从 kafka 消费写入，请合理设计消费者，尽可能的一个子表数据由一个消费者去消费并写入，避免由设计产生的乱序。
### 25 我想统计下前后两条写入记录之间的时间差值是多少？
使用 DIFF 函数，可以查看时间列或数值列前后两条记录的差值，非常方便，详细说明见 SQL手册->函数->DIFF
