Answer 1

你可以試試這個：

select * from tablename where log 
not exists(select 1 from tablename where 
     log like '%"Hour": "01", "Minute": "00"%' 
    or log like '%"Hour": "01", "Minute": "30"%' 
    or log like '%"Hour": "02", "Minute": "00"%' 
    or log like '%"Hour": "23", "Minute": "30"%' 
    or log like '%"Hour": "00", "Minute": "00"%' 
    or log like '%"Hour": "00", "Minute": "30"%')
