插入我的表时,我收到此错误:
错误:关系“项目”的列“品牌”不存在
brandId 列上有一个外键约束,将其链接到另一个表的 id。
我插入的表是这样定义的:
Column | Type | Modifiers | Storage | Stats target | Description
---------+---------+-----------------------------------------------------+----------+--------------+-------------
id | integer | not null default nextval('"Item_id_seq"'::regclass) | plain | |
name | text | not null | extended | |
price | money | not null | plain | |
sizes | json | not null | extended | |
brandId | integer | not null | plain | |
deptId | integer | not null | plain | |
Indexes:
"item_pk" PRIMARY KEY, btree (id)
Foreign-key constraints:
"Item_fk0" FOREIGN KEY ("brandId") REFERENCES "Brand"(id)
"Item_fk1" FOREIGN KEY ("deptId") REFERENCES "Department"(id)
我正在尝试执行以下插入语句:
INSERT INTO "Item" (name, price, sizes, brandId, deptId) VALUES
('Air Force 1', '120.00', '{"12" : 1 , "10" : 12}',
(SELECT id FROM "Brand" WHERE name= 'Nike'),
(SELECT id FROM "Department" WHERE name= 'Mens Shoes'));
我数据库中的所有 id 列都是串行类型。
Brand 和 Department 表已经被填充,并且这些 select 语句已经过测试并且可以正常工作。
