The following functions are created:
Create function JSON_VALID and test cases
Create function JSON_DEPTH and test cases
Create function JSON_LENGTH and test cases
Create function JSON_EQUALS and test cases
Create function JSON_NORMALIZE and test cases
Create function JSON_TYPE and test cases
Create function JSON_OBJECT and test cases
Create function JSON_ARRAY and test cases
Create function JSON_KEYS and test cases
Create function JSON_EXISTS and test cases
Create function JSON_QUOTE/JSON_UNQUOTE and test cases
Create function JSON_COMPACT/DETAILED/LOOSE and test cases
Create function JSON_MERGE and test cases
Create function JSON_MERGE_PATCH and test cases
Create function JSON_VALUE and test cases
Create function JSON_QUERY and test cases
Create function JSON_CONTAINS and test cases
Create function JSON_ARRAY_APPEND and test cases
Create function JSON_ARRAY_INSERT and test cases
Create function JSON_INSERT/REPLACE/SET and test cases
Create function JSON_REMOVE and test cases
Create function JSON_CONTAINS_PATH and test cases
Create function JSON_OVERLAPS and test cases
Create function JSON_EXTRACT and test cases
Create function JSON_SEARCH and test cases
