How to use Python to operate QuestDB

To operate QuestDB using Python, you first need to install the 'questdb' library. You can use the pip command to install the library, such as running the following command from the command line: pip install questdb After the installation is completed, you can introduce the 'questdb' library into the Python script and connect to the QuestDB database. Here is a simple connection example: python from questdb import connect #Connect to the local QuestDB database conn = connect(user="admin", password="quest", host="localhost", port=9000) In the above code, the 'user', 'password', 'host', and 'port' parameters are required to connect to the QuestDB database. It can be modified according to the actual situation. After the connection is successful, various operations can be performed, such as creating tables, inserting data, updating data, and querying data. Here are a few example operations: **Create Table:** python #Create a table named 'users' conn.execute("CREATE TABLE users (id INT, name STRING, age INT)") **Insert data:** python #Insert a piece of data into the 'users' table conn.execute("INSERT INTO users (id, name, age) VALUES (1, 'John', 28)") **Update data:** python #Update the age of the record with id 1 in the "users" table to 30 conn.execute("UPDATE users SET age = 30 WHERE id = 1") **Query data:** python #Query all data in the 'users' table result = conn.execute("SELECT * FROM users") for row in result: print(row) In the above code, SQL statements can be executed using the 'execute()' method. When querying data, the query results can be obtained by traversing the 'result' object. The above is a basic example of using Python to operate QuestDB, which you can modify and expand according to your own needs. At the same time, you can also refer to the official documentation of QuestDB for more detailed information and examples: [QuestDB Python Driver Documentation]（ https://questdb.io/docs/reference/interfaces/python/ ）.
