插入不重复的值
Insert values without duplicates
我想为所有商家添加付款方式 3。我怎样才能用 MariaDB 做到这一点。
我喜欢这样:
insert into business_payment_type
(id_payment_type, active)
select "4", "1"
from business_payment_type
where id_business in (select distinct(id_business)
from business_payment_type)
但是return错误:
1364 - Field 'id_business' doesn't have a default value
Table 喜欢图片
在一条语句中获取所有 id_business
值和新值,然后 INSERT
该记录集到您的 table。
INSERT INTO business_payment_type (
id_business
,id_payment_type
,active
)
SELECT DISTINCT
id_business
,4 AS id_payment_type
,1 AS active
FROM business_payment_type;
I want to add payment type 3 to all businesses.
所有商家大概都在营业table。因此:
insert into business_payment_type (id_business, id_payment_type, active)
select id_business, 3, 1 from business;
