Greetings.

the table function JSON_TABLE is not supported. Without it, your statement works just fine.

SELECT  id
        , knowledge_type_code
        , knowledge_data
        , url_routing
        , keyword
        , update_by
        , update_time
        , sort
FROM "SUNYA-SYSTEM".sys_knowledge_base
WHERE ( ( Json_Unquote( Json_Extract( knowledge_data, '$.title' ) ) LIKE '%记%'
            OR EXISTS ( SELECT 1
                        FROM dual AS drug
                        WHERE drug.drugsname LIKE '%记%' ) )
        AND knowledge_type_code = 'literatureGuidelines' )
ORDER BY sort ASC
;

Yes of course, because I replaced your table function and altered the meaning of your query.
It definitely will either not execute or return wrong results because its not the same query.

Ok, thank you. Is there any possibility to consider support in the future?
