+## CASE Expressions
+
+### Syntax
+
+```txt
+CASE value WHEN compare_value THEN result [WHEN compare_value THEN result ...] [ELSE result] END
+CASE WHEN condition THEN result [WHEN condition THEN result ...] [ELSE result] END
+```
+
+### Description
+CASE expressions let you use IF ... THEN ... ELSE logic in SQL statements without having to invoke procedures. 
+
+The first CASE syntax returns the `result` for the first `value`=`compare_value` comparison that is true. 
+
+The second syntax returns the `result` for the first `condition` that is true. 
+
+If no comparison or condition is true, the result after ELSE is returned, or NULL if there is no ELSE part.
+
+The return type of the CASE expression is the result type of the first WHEN WHEN part, and the result type of the other WHEN WHEN parts and ELSE parts can be converted to them, otherwise TDengine will report an error.
+
+### Examples
+
+A device has three status codes to display its status. The statements are as follows:
+
+```sql
+SELECT CASE dev_status WHEN 1 THEN 'Running' WHEN 2 THEN 'Warning' WHEN 3 THEN 'Downtime' ELSE 'Unknown' END FROM dev_table;
+```
+
+The average voltage value of the smart meter is counted. When the voltage is less than 200 or more than 250, it is considered that the statistics is wrong, and the value is corrected to 220. The statement is as follows:
+
+```sql
+SELECT AVG(CASE WHEN voltage < 200 or voltage > 250 THEN 220 ELSE voltage END) FROM meters;
+```
+
 ## JOIN
 
 TDengine supports natural joins between supertables, between standard tables, and between subqueries. The difference between natural joins and inner joins is that natural joins require that the fields being joined in the supertables or standard tables must have the same name. Data or tag columns must be joined with the equivalent column in another table.

 SELECT * FROM (SELECT COUNT(*) AS cnt, FIRST(ts) AS fst, status FROM temp_tb_1 STATE_WINDOW(status)) t WHERE status = 2;

+TDengine also supports the use of CASE expressions in state quantities. It can express that the beginning of a state is triggered by meeting a certain condition, and the end of this state is triggered by meeting another condition. For example, if the normal voltage range of the smart meter is 205V to 235V, you can judge whether the circuit is normal by monitoring the voltage.
+
+```
+SELECT tbname, _wstart, CASE WHEN voltage >= 205 and voltage <= 235 THEN 1 ELSE 0 END status FROM meters PARTITION BY tbname STATE_WINDOW(CASE WHEN voltage >= 205 and voltage <= 235 THEN 1 ELSE 0 END);

 The primary key, i.e. timestamp, is used to determine which session window a row belongs to. As shown in the figure below, if the limit of time interval for the session window is specified as 12 seconds, then the 6 rows in the figure constitutes 2 time windows, [2019-04-28 14:22:10，2019-04-28 14:22:30] and [2019-04-28 14:23:10，2019-04-28 14:23:30] because the time difference between 2019-04-28 14:22:30 and 2019-04-28 14:23:10 is 40 seconds, which exceeds the time interval limit of 12 seconds.

 - field_set 中的每个数据项都需要对自身的数据类型进行描述, 比如 1.2f32 代表 FLOAT 类型的数值 1.2, 如果不带类型后缀会被当作 DOUBLE 处理;
 - timestamp 支持多种时间精度。写入数据的时候需要用参数指定时间精度，支持从小时到纳秒的 6 种时间精度。
 - 为了提高写入的效率，默认假设同一个超级表中 field_set 的顺序是一样的（第一条数据包含所有的 field，后面的数据按照这个顺序），如果顺序不一样，需要配置参数 smlDataFormat 为 false，否则，数据写入按照相同顺序写入，库中数据会异常。（3.0.1.3 之后的版本 smlDataFormat 默认为 false） [TDengine 无模式写入参考指南](/reference/schemaless/#无模式写入行协议)

+
+### 语法
+
+```txt
+CASE value WHEN compare_value THEN result [WHEN compare_value THEN result ...] [ELSE result] END
+CASE WHEN condition THEN result [WHEN condition THEN result ...] [ELSE result] END
+```
+
+### 说明
+
+TDengine 通过 CASE 表达式让用户可以在 SQL 语句中使用 IF ... THEN ... ELSE 逻辑。
+
+第一种 CASE 语法返回第一个 value 等于 compare_value 的 result，如果没有 compare_value 符合，则返回 ELSE 之后的 result，如果没有 ELSE 部分，则返回 NULL。
+
+第二种语法返回第一个 condition 为真的 result。 如果没有 condition 符合，则返回 ELSE 之后的 result，如果没有 ELSE 部分，则返回 NULL。
+
+CASE 表达式的返回类型为第一个 WHEN THEN 部分的 result 类型，其余 WHEN THEN 部分和 ELSE 部分，result 类型都需要可以向其转换，否则 TDengine 会报错。
+
+### 示例
+
+某设备有三个状态码，显示其状态，语句如下：
+
+```sql
+SELECT CASE dev_status WHEN 1 THEN 'Running' WHEN 2 THEN 'Warning' WHEN 3 THEN 'Downtime' ELSE 'Unknown' END FROM dev_table;
+```
+
+统计智能电表的电压平均值，当电压小于 200 或大于 250 时认为是统计有误，修正其值为 220，语句如下：
+
+```sql
+SELECT AVG(CASE WHEN voltage < 200 or voltage > 250 THEN 220 ELSE voltage END) FROM meters;
+```
+
 ## JOIN 子句
 
 TDengine 支持“普通表与普通表之间”、“超级表与超级表之间”、“子查询与子查询之间” 进行自然连接。自然连接与内连接的主要区别是，自然连接要求参与连接的字段在不同的表/超级表中必须是同名字段。也即，TDengine 在连接关系的表达中，要求必须使用同名数据列/标签列的相等关系。
