How do you query a database in MySQL?

To query the MySQL database, you can follow these steps:

1. Open the MySQL client or use a visual tool (such as phpMyAdmin) to connect to the MySQL server.
2. Enter your username and password to log in to the MySQL server.
3. Switch to database_name.
4. Retrieve columns 1, 2, etc. from table name where a certain condition is met.
5. Execute the query statement. Use a MySQL client or visualization tool to execute the query statement and view the results.

Here is an example for querying the names and salaries of all employees in a table named “employees”.

SELECT name, salary FROM employees;

Please make sure you are properly connected to the MySQL server and have selected the correct database before executing the query.
