How to use the EXTRACT() function in MySQL and MariaDB databases

MySQL and MariaDB contain the EXTRACT() function, which is used to extract a specific part (year, month, day, hour, etc.) from a "date" or "date and time" expression. Column names or other expressions can also be used as parameters in the function to retrieve individual date or time components of a value in queries, where the function returns the extracted component as an integer value or as a string, based on the chosen unit. In queries, you can work with individual components of date and time information and perform various operations on the basis of these components.
