Mastering Advanced SQL Techniques with MySQL

MySQL provides five data types for temporal values, i.e., `DATE`, `TIME`, `DATETIME`, `TIMESTAMP`, and `YEAR`. To work with these data types, we must first create corresponding values. For that purpose, we work with the following table:

DROP TABLE IF EXISTS date_and_time;
-- Generate a table that records temporal values.
CREATE TEMPORARY TABLE date_and_time
(
    a_date      DATE,
    a_time      TIME,
    a_datetime  DATETIME,
    a_timestamp TIMESTAMP,
    a_year      YEAR
);

As we can observe from the above SQL script, the table `date_and_time` contains five columns that represent the five temporal data types of MySQL: `a_date` for `DATE`, `a_time` for `TIME`, `a_datetime` for `DATETIME`, `a_timestamp` for `TIMESTAMP`, and `a_year` for `YEAR`. Intuitively, we can create a row in `date_and_time` by specifying the values for the five columns literally. However, this is tedious and may not even work when automated creation of temporal values is necessary.

# Create date values

As mentioned before, one common way of creating a date value is using a literal string that provides a date in a particular format:
