--------------------------------------------------------------

hi [~zhztheplayer] Some discussions about the adding of MySQL JSON functions in 
the dev list. I think it's a great idea. We can start talking about this.

> The data in json can be =, <, <=, >, >=, <>,! =, and <=>. But the data types 
> in json can be diverse, so when you compare different types, you have a 
> priority, and the high priority is greater than the low priority (you can 
> view the types with the JSON_TYPE() function). The priorities are as follows:
>  BOOLEAN
>  ARRAY
>  OBJECT
>  STRING
>  INTEGER
> DOUBLE
>  NULL
