xuqianjin updated CALCITE-2791:
-------------------------------
Description:
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:
BLOB
BIT
OPAQUE
DATETIME
TIME
DATE
BOOLEAN
ARRAY
OBJECT
STRING
INTEGER,
DOUBLE
NULL
