> 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
> LONG
> DOUBLE
> NULL
