What is the SELECT command in SQL?
The SELECT command is used to query data from a database. It allows you to specify which columns to retrieve.
Can you give me an example of a SELECT statement?
Sure! A basic example is: SELECT * FROM employees;
This retrieves all columns from the employees table.
How do I select specific columns?
You can specify columns by listing them: SELECT first_name, last_name FROM employees;
This retrieves only the first and last names.
What if I want to filter the results?
You can use the WHERE clause. For example: SELECT * FROM employees WHERE department = 'Sales';
This filters results to only show employees in the Sales department.
