    ,name string 
    , course array<string>)

102 student3 java,hadoop 
103 student4 .net,hadoop

** **等於或** **包含？ –

具有以上數據的課程數據類型，我想篩選正在做hadoop課程的學生 –

select * 
from student 
where array_contains (course,'hadoop') 
;

+-----+----------+--------------------------+ 
| id | name |   course   | 
+-----+----------+--------------------------+ 
| 100 | student1 | ["java",".net","hadoop"] | 
| 101 | student2 | [".net","hadoop"]  | 
| 102 | student3 | ["java","hadoop"]  | 
| 103 | student4 | [".net","hadoop"]  | 
| 105 | student6 | ["java",".net","hadoop"] | 
| 106 | student7 | [".net","hadoop"]  |
