An example of an AI chatbot conversation about logical operators in SQL.
What are logical operators in SQL?
Logical operators in SQL are used to combine multiple conditions in a query. The main ones are AND, OR, and NOT.
Can you give me an example of using AND in a SQL query?
Sure! For example: SELECT * FROM employees WHERE department = 'Sales' AND salary > 50000; This retrieves employees in Sales with a salary over 50,000.
What about using OR?
An example using OR would be: SELECT * FROM employees WHERE department = 'Sales' OR department = 'Marketing'; This gets employees from either department.
How does NOT work in SQL?
The NOT operator negates a condition. For instance: SELECT * FROM employees WHERE NOT department = 'HR'; This retrieves employees not in the HR department.
