+## Json类型使用说明
+- 语法说明
+
+  1. 创建json类型tag
+
+     ```mysql
+     create stable s1 (ts timestamp, v1 int) tags (info json)
+
+     create table s1_1 using s1 tags ('{"k1": "v1"}')
+     ```
+  3. json取值操作符 ->
+
+     ```mysql   
+     select * from s1 where info->'k1' = 'v1'
+
+     select info->'k1' from s1 
+     ```
+  4. json key是否存在操作符 contains
+
+     ```mysql
+     select * from s1 where info contains 'k2'
+    
+     select * from s1 where info contains 'k1'
+     ```
+     
+- 支持的操作
+
+  1. 在where条件中时，支持函数match/nmatch/between and/like/and/or/is null/is no null，不支持in
+
+     ```mysql 
+     select * from s1 where info→'k1' match 'v*'; 
+
+     select * from s1 where info→'k1' like 'v%' and info contains 'k2';
+
+     select * from s1 where info is null; 
+  
+     select * from s1 where info->'k1' is not null
+     ```
+
+  2. 支持json tag放在group by、order by、join子句、union all以及子查询中，比如group by json->'key'
+
+  3. 支持distinct操作.
+
+     ```mysql 
+     select distinct info→'k1' from s1
+     ```
+  
+  5. 标签操作
+    
+     支持修改json标签值（全量覆盖）
+
+     支持修改json标签名 
+  
+     不支持添加json标签、删除json标签、修改json标签列宽
+
+- 其他约束条件
+  
+  1. 只有标签列可以使用json类型，如果用json标签，标签列只能有一个。
+  
+  2. 长度限制：json 中key的长度不能超过256，并且key必须为可打印ascii字符；json字符串总长度不超过4096个字节。
+
+  3. json格式限制：
+
+     1. json输入字符串可以为空（"","\t"," "或null）或object，不能为非空的字符串，布尔型和数组。
+     2. object 可为{}，如果object为{}，则整个json串记为空。key可为""，若key为""，则json串中忽略该k-v对。
+     3. value可以为数字(int/double)或字符串或bool或null，暂不可以为数组。不允许嵌套。
+     4. 若json字符串中出现两个相同的key，则第一个生效。
+     5. json字符串里暂不支持转义。
+  
+  4. 当查询json中不存在的key时，返回NULL
+
+  5. 当json tag作为子查询结果时，不再支持上层查询继续对子查询中的json串做解析查询。
+  
+     比如暂不支持 
+     ```mysql 
+     select jtag→'key' from (select jtag from stable)
+     ```
+  
+     不支持 
+     ```mysql 
+     select jtag->'key' from (select jtag from stable) where jtag->'key'>0

 **Availability of is no null**
 
 Is not null supports all types of columns. Non-null expression is < > "" and only applies to columns of non-numeric types.
+
+**Restrictions on order by**
+
+- A non super table can only have one order by.
+- The super table can have at most two order by expression, and the second must be ts.
+- Order by tag must be the same tag as group by tag. TBNAME is as logical as tag.
+- Order by ordinary column must be the same ordinary column as group by or top/bottom. If both group by and top / bottom exist, order by must be in the same column as group by.
+- There are both order by and group by. The internal of the group is sorted by ts
+- Order by ts.
+
+## JSON type instructions
+- Syntax description
+
+  1. Create JSON type tag
+
+     ```mysql
+     create stable s1 (ts timestamp, v1 int) tags (info json)
+
+     create table s1_1 using s1 tags ('{"k1": "v1"}')
+     ```
+  3. JSON value operator(->)
+
+     ```mysql   
+     select * from s1 where info->'k1' = 'v1'
+
+     select info->'k1' from s1 
+     ```
+  4. JSON key existence operator(contains)
+
+     ```mysql
+     select * from s1 where info contains 'k2'
+    
+     select * from s1 where info contains 'k1'
+     ```
+
+- Supported operations
+
+  1. In where condition，support match/nmatch/between and/like/and/or/is null/is no null，in operator is not support.
+
+     ```mysql 
+     select * from s1 where info→'k1' match 'v*'; 
+
+     select * from s1 where info→'k1' like 'v%' and info contains 'k2';
+
+     select * from s1 where info is null; 
+  
+     select * from s1 where info->'k1' is not null
+     ```
+
+  2. JSON tag is supported in group by、order by、join clause、union all and subquery，like group by json->'key'
+
+  3. Support distinct operator.
+
+     ```mysql 
+     select distinct info→'k1' from s1
+     ```
+
+  5. Tag
+
+     Support change JSON tag（full coverage）
+
+     Support change the name of JSON tag
+
+     Not support add JSON tag, delete JSON tag
+
+- Other constraints
+
+  1. Only tag columns can use JSON type. If JSON tag is used, there can only be one tag column.
+
+  2. Length limit:The length of the key in JSON cannot exceed 256, and the key must be printable ASCII characters; The total length of JSON string does not exceed 4096 bytes.
+
+  3. JSON format restrictions:
+
+    1. JSON input string can be empty (""," ","\t" or null) or object, and cannot be nonempty string, boolean or array.
+    2. Object can be {}, if the object is {}, the whole JSON string is marked as empty. The key can be "", if the key is "", the K-V pair will be ignored in the JSON string.
+    3. Value can be a number (int/double) or string, bool or null, not an array. Nesting is not allowed.
+    4. If two identical keys appear in the JSON string, the first one will take effect.
+    5. Escape is not supported in JSON string.
+
+  4. Null is returned when querying the key that does not exist in JSON.
+
+  5. When JSON tag is used as the sub query result, parsing and querying the JSON string in the sub query is no longer supported in the upper level query.
+
+     The following query is not supported:
+     ```mysql 
+     select jtag→'key' from (select jtag from stable)
+      
+     select jtag->'key' from (select jtag from stable) where jtag->'key'>0
+     ```
