MySQL CONCAT: Combine Strings Easily
In MySQL, the CONCAT function can be used to concatenate strings. For example, here is a query example:
SELECT CONCAT(first_name, ' ', last_name) AS full_name
FROM employees;
In this example, we are querying the first_name and last_name columns from the employees table, concatenating them together using the CONCAT function, and then returning the result as an alias called full_name.
You can also use constant strings in the CONCAT function, as shown below:
SELECT CONCAT('Hello, ', first_name) AS greeting
FROM employees;
This will add a fixed greeting before the first name and then return the result as an alias called greeting.
