Write a query to get all the name and price from a product database in MySQL using Rust sqlx library<|im_end|>
<|im_start|>assistant
Here is code of a Rust sqlx query that retrieves the name and price of all products from a MySQL database:

````
use sqlx::{mysql::{MySqlPool, MySqlQueryAs}, query_as};

#[derive(Debug, sqlx::FromRow)]
struct Product {
    name: String,
    price: f64,
}

#[tokio::main]
async fn main() -> Result<(), sqlx::Error> {
    // Replace "mysql://user:password@localhost/database" with your database connection string
    let pool = MySqlPool::connect("mysql://user:password@localhost/database").await?;

    let products: Vec<Product> = query_as!(Product, "SELECT name, price FROM products")
        .fetch_all(&pool)
        .await?;

    for product in products {
        println!("Name: {}, Price: {}", product.name, product.price);
    }

    Ok(())
}
````

In this example, we define a Product struct with name and price fields that correspond to the columns in the products table. We use the sqlx::query_as macro to build a query that selects the name and price columns from the products table. We then use the fetch_all method on the resulting QueryAs object to execute the query and retrieve a Vec<Product>.

Finally, we loop through the Vec<Product> and print out the name and price fields for each product.<|im_end|>

How to write SQL table using Python3?<|im_end|>
<|im_start|>assistant
You can use the Python package **`sqlite3`** to create and manipulate SQL tables. Here is an example of how to create a simple table:

```python
import sqlite3

# Create a connection to the database
conn = sqlite3.connect('example.db')

# Create a cursor object to execute SQL commands
cursor = conn.cursor()

# Create a table called 'users'
cursor.execute('''CREATE TABLE users
                  (id INTEGER PRIMARY KEY, name TEXT, age INTEGER)''')

# Save the changes and close the connection
conn.commit()
conn.close()
```

In this example, we first create a connection to a new SQLite database called **`example.db`**. Then we create a cursor object to execute SQL commands on this database. We use the **`execute()`** method to create a new table called **`users`** with three columns: **`id`**, **`name`**, and **`age`**. Finally, we commit the changes and close the connection.

You can modify this code to add more columns or change the data types of the columns. You can also insert data into the table using SQL commands executed through the **`cursor`** object.<|im_end|>
