prompt英文版本如下：

### Task
Generate a SQL query to answer the following question:
`What is our total revenue by product in the last week?`

### Database Schema
This query will run on a database whose schema is represented in this string:
CREATE TABLE products (
  product_id INTEGER PRIMARY KEY, -- Unique ID for each product
  name VARCHAR(50), -- Name of the product
  price DECIMAL(10,2), -- Price of each unit of the product
  quantity INTEGER  -- Current quantity in stock
);

CREATE TABLE customers (
   customer_id INTEGER PRIMARY KEY, -- Unique ID for each customer
   name VARCHAR(50), -- Name of the customer
   address VARCHAR(100) -- Mailing address of the customer
);

CREATE TABLE salespeople (
  salesperson_id INTEGER PRIMARY KEY, -- Unique ID for each salesperson
  name VARCHAR(50), -- Name of the salesperson
  region VARCHAR(50) -- Geographic sales region
);

CREATE TABLE sales (
  sale_id INTEGER PRIMARY KEY, -- Unique ID for each sale
  product_id INTEGER, -- ID of product sold
  customer_id INTEGER,  -- ID of customer who made purchase
  salesperson_id INTEGER, -- ID of salesperson who made the sale
  sale_date DATE, -- Date the sale occurred
  quantity INTEGER -- Quantity of product sold
);

CREATE TABLE product_suppliers (
  supplier_id INTEGER PRIMARY KEY, -- Unique ID for each supplier
  product_id INTEGER, -- Product ID supplied
  supply_price DECIMAL(10,2) -- Unit price charged by supplier
);

-- sales.product_id can be joined with products.product_id
-- sales.customer_id can be joined with customers.customer_id
-- sales.salesperson_id can be joined with salespeople.salesperson_id
-- product_suppliers.product_id can be joined with products.product_id

### SQL
Given the database schema, here is the SQL query that answers `What is our total revenue by product in the last week?`:
```sql

### Task
生成一个SQL来回答如下问题:
`上一周按照产品分组查询各个产品的总计收入是多少？`

### Database Schema
查询语句基于如下使用字符串描述的数据库:
CREATE TABLE products (
  product_id INTEGER PRIMARY KEY, -- 每个产品的唯一ID
  name VARCHAR(50), -- 产品名称
  price DECIMAL(10,2), -- 产品价格
  quantity INTEGER  -- 当前库存量
);

CREATE TABLE customers (
   customer_id INTEGER PRIMARY KEY, -- 每个客户端唯一ID
   name VARCHAR(50), -- 客户姓名
   address VARCHAR(100) -- 客户端email地址
);

CREATE TABLE salespeople (
  salesperson_id INTEGER PRIMARY KEY, -- 每个销售人员ID
  name VARCHAR(50), -- 销售人员姓名
  region VARCHAR(50) -- 销售人员的地理销售区域，也就是销售员的负责区域
);

CREATE TABLE sales (
  sale_id INTEGER PRIMARY KEY, -- 每笔销售订单的ID
  product_id INTEGER, -- 售出的商品ID
  customer_id INTEGER,  -- 购买的客户ID
  salesperson_id INTEGER, -- 销售人员ID
  sale_date DATE, -- 销售日期
  quantity INTEGER -- 产品的售出数量
);

CREATE TABLE product_suppliers (
  supplier_id INTEGER PRIMARY KEY, -- 供应商ID
  product_id INTEGER, -- 供应商的产品ID
  supply_price DECIMAL(10,2) -- 供应商的单价
);

-- sales.product_id 可以和 products.product_id进行连接
-- sales.customer_id 可以和customers.customer_id进行连接
-- sales.salesperson_id 可以和 salespeople.salesperson_id进行连接
-- product_suppliers.product_id 可以和 products.product_id进行连接

### SQL
通过以上给定的数据库描述，我再重复一遍编写SQL查询语句来回答 `上一周按照产品分组查询各个产品的总计收入是多少?`:
```sql

默认为语法是 PostgreSQL ，输出如下SQL查询语句：

SELECT p.name, SUM(s.quantity * ps.supply_price) AS total_revenue FROM products p JOIN sales s ON p.product_id = s.product_id JOIN product_suppliers ps ON p.product_id = ps.product_id WHERE s.sale_date >= (CURRENT_DATE - interval '1 week') GROUP BY p.name;

我自己格式化后的效果：

SELECT   
    p.name,   
    SUM(s.quantity * ps.supply_price) AS total_revenue   
FROM   
    products p   
JOIN   
    sales s   
ON   
    p.product_id = s.product_id   
JOIN   
    product_suppliers ps   
ON   
    p.product_id = ps.product_id   
WHERE   
    s.sale_date >= (CURRENT_DATE - INTERVAL '1 week')   
GROUP BY   
    p.name;

我让它生成MySQL语法的他不会，还是输出PGsql的语句，可以自己找sql翻译工具进行转换，相信通过不断增加MySQL的训练数据进行训练，它支持MySQL语法指日可待。
