问题描述
我有一个包含一些数据的临时表 (products_temp)，我还有另一个表(产品)需要插入数据.我需要在新记录上手动设置一些常量，例如 vendor_id=1 等...
I have a temporary table (products_temp) with some data, and I have another table (products) I need to insert the data into. I have some constants I need to set manually on new records, like vendor_id=1, etc...
是否可以在一个请求中插入临时表数据和常量?
Is it possible to do the insertion with the temporary table data and the constants in one request?
temp_products:
temp_products:
product_name | product_desc | category_name | mf_name ...
产品(category_name，mf_name 不在):
products (category_name, mf_name is not in):
product_id | product_name | product_desc | vendor_id | distributor_id ...
常量:
vendor_id=1, distributor_id=2
推荐答案
使用 INSERT ... SELECT 语句，您在其中选择常量值以及来自 products_temp 的数据:
Use an INSERT ... SELECT statement where you are selecting constant values as well as data from products_temp:
INSERT INTO products (product_data, vendor_id)
SELECT data, '1' FROM products_temp
