When using MySQL, you can use the MAKETIME() function to return a time from the various time parts.
In other words, you provide three arguments; the hour, the minutes, and the seconds. The MAKETIME() function will then return the time value based on those two arguments.
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().
