What are SQL functions and how do I use them?
SQL functions are predefined operations that can be used to perform calculations, manipulate data, and return values. They can be categorized into aggregate functions, scalar functions, and window functions.
Can you give me examples of some common SQL functions?
Sure! Common SQL functions include COUNT(), SUM(), AVG(), MIN(), MAX() for aggregate functions, and UPPER(), LOWER(), LENGTH() for string manipulation.
How do I use the COUNT() function in a query?
You can use the COUNT() function to count the number of rows that match a specified condition. For example: SELECT COUNT(*) FROM employees WHERE department = 'Sales'; will return the number of employees in the Sales department.
What is the difference between aggregate functions and scalar functions?
Aggregate functions operate on a set of values and return a single value, while scalar functions operate on a single value and return a single value.
