Meanwhile, extra characters at the end of str are ignored: Scanning starts at the beginning of str and fails if format is found not to match. Here are a couple of Dates in Navicat for MySQL 16: Moreover, if the date, time, or datetime value extracted from str is invalid, STR_TO_DATE() returns NULL and produces a warning. a DATETIME value if the format string contains both date and time parts.a TIME value if the string contains only time. a DATE value if the string contains only date.It takes a date string and a format string and returns: The second argument can have a fractional part for milliseconds: The STR_TO_DATE() FunctionĪnother option for creating a DATE, TIME, or DATETIME is to use the STR_TO_DATE() function. If you're looking to create a TIME only, MAKETIME() returns a time value calculated from the hour, minute, and second arguments: This SELECT statement includes the day as well: The MAKETIME() Function Here's an example that sets the year and month only: MAKEDATE() with a day of 1 will give you a DATE for the first day of the given year, and then you can add to it the month and day with DATE_ADD(). In that case, you can make a DATE by combining MAKEDATE() with DATE_ADD(). The downside to this function should be readily obvious it takes some calculation to determine the dayofyear if you have a year, month, and day. For instance, MAKEDATE(2021, 200) would return a Date of "". It takes a year and dayofyear and returns the resulting Date value. In Part 3, we took a brief look at the MAKEDATE() function. In this installment, we'll be covering a few ways to create dates and times in MySQL. In this this series on Dates and Times, we've explored MySQL's five temporal data types, as well as some of its many date/time-oriented functions.
