Is there a way I can use a combination of hard values and a subquery to insert into a table with one command?
有没有办法可以使用硬值和子查询的组合来插入一个命令的表？
For example:
例如：
INSERT INTO suppliers (supplier_id, supplier_name, supplier_type)
SELECT account_no, name
FROM customers
WHERE city = 'San Diego';
I need supplier_type to be 3. So can I do the following for the second line?
我需要supplier_type为3.所以我可以为第二行执行以下操作吗？
SELECT account_no, name, supplier_type = 3
supplier_type is not in the customers table
supplier_type不在customers表中

Just add it with your SELECT fields.
只需将其与SELECT字段一起添加即可。
INSERT INTO suppliers (supplier_id, supplier_name, supplier_type)
SELECT account_no, name, 3 AS supplier_type
FROM customers
WHERE city = 'San Diego';
