錯誤代碼：MySQL更新查詢中出現1064

Question

Table: immunization                 
id  vac_id  vaccine_id
1   5       0
2   5       0
3   3       0
4   4       0
5   4       0

Table: vaccine
id  vac_id
8   1
9   2
10  3
11  4
12  5

我有兩個表，現在我想通過匹配accurate.vac_id = immunization.vac_id將疫苗表的id設置為免疫表的vacuum_id

為此，我已經使用了查詢，但是卻收到錯誤1064

UPDATE immunization
SET  immunization.vaccine_id = vaccine.id
FROM vaccine,immunization
WHERE  vaccine.vac_id = immunization.vac_id

Answer 1

UPDATE immunization i
join vaccine v
on i.vac_id=v.vac_id
SET  i.vaccine_id = v.id

集最后
