1. The error is as follows
2. Check the code
3. Analysis errors
According to the error message you provided, you encountered a MySQL connector error with error code 1046 and error message "No database selected". This error usually occurs when you have not selected a database before attempting to perform a SQL query or operation.
To get around this, you can specify a default database when connecting to MySQL. When using the Python mysql.connector
library to connect, you can specify the default database in the connection parameters:
import mysql.connector # Connect to the MySQL server and specify the default database cnx = mysql.connector.connect(user='username', password='password', host='localhost', database='mydatabase')
Be sure to replace username
, password
, localhost
, and mydatabase
with your actual connection parameters.
Before executing the SQL statement, make sure you have selected the correct database. For example, the following statement can be used to select a database before creating a table: cursor.execute("USE mydatabase;")
4. Modify the code
5. View the running results
Note: If the newly created table is created successfully, create a new table again, otherwise the operation will report an error that the table already exists.
Hope to help you, thank you~
