When using MySQL, you can use the MAKEDATE() function to return a date from the year and day-of-year parts.
In other words, you provide two arguments; one being the year, and the other being the day-of-year. The MAKEDATE() function will then return the date value based on those two arguments.
When using MySQL, you can use the LAST_DAY() function to return the last day of a given month.
You can provide the current date, or you can provide another specified date (for example, a date from a column in a database), and LAST_DAY() will return the last day of the month for that date.
The MySQL MICROSECOND() function is used to return the microsecond component from a time value.
The return value for this function is in the range 0 to 999999. Below are examples to demonstrate.
The MySQL SECOND() function is used to return the second component from a time value.
The return value for this function is in the range 0 to 59. Below are examples to demonstrate.
The MySQL MINUTE() function is used to return the minute component from a time value.
The return value for this function is in the range 0 to 59. Below are examples to demonstrate.
The MySQL HOUR() function is used to return the hour component from a time value.
The return value for a time-of-day value will be between 0 and 23, however the range returned by this function could be much larger, due to the fact that a time data type isn’t limited to just a time of day (it can also be used to represent elapsed time or a time interval between two events). This means that the returned value could be greater than 24 hours or even a negative value.
In MySQL, you can use the GET_FORMAT() function to return a format string for the provided arguments. This can be useful when you need to provide a format string to another function, such as DATE_FORMAT() or STR_TO_DATE().
The MySQLÂ FROM_UNIXTIME() function enables you to return a date representation of a Unix timestamp.
More specifically, it returns the Unix timestamp as a value in ‘YYYY-MM-DD HH:MM:SS’ or YYYYMMDDHHMMSS format, depending on whether the function is used in a string or numeric context.
