How can SQL concatenate multiple fields together?

In SQL, you can use the CONCAT function to concatenate multiple fields together. For example, if there is a students table that includes the first_name and last_name fields, you can combine these two fields into a full name using the following statement:

SELECT CONCAT(first_name, ' ', last_name) AS full_name
FROM students;

This will return a new column named full_name containing the complete name. You can also add any number of fields in the CONCAT function, separated by commas.
