![]() ![]() This returns the full format string for a given date format, which saves you from having to remember the format string to use. You can also use the GET_FORMAT() function in the second argument to DATE_FORMAT(). Result: ERROR 1064 (42000): You have an error in your SQL syntax check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 1 The GET_FORMAT() Function Result: ERROR 1064 (42000): You have an error in your SQL syntax check the manual that corresponds to your MariaDB server version for the right syntax to use near ')' at line 1Īnd another example: SELECT DATE_FORMAT('') +-+ Missing ArgumentĬalling DATE_FORMAT() with the wrong number of arguments, or without passing any arguments, results in an error: SELECT DATE_FORMAT() When passed any invalid arguments, DATE_FORMAT() returns null: SELECT DATE_FORMAT('Homer', 'Simpson') Here, we pass NOW() as the date argument in order to format the current date: SELECT DATE_FORMAT(NOW(), '%r %W, %D %M %Y') So I guess the assumption is that if you want to use the Thai year, then the date you pass will already use the Thai year. The year 2030 would be 2573 when using the Thai calendar. In this case, the last one is Thai, and although it uses Thai characters for the month name and day name, it doesn’t change the year to the Thai calendar. Result: fr_FR: vendredi, 25th janvier 2030 When this is specified, it makes the function independent from the session settings. Starting with MariaDB 10.3.2, an optional third argument can be used to specify the locale. The default is always en_US regardless of the system’s locale setting. The date, time, or datetime values contained in str should be given in the format indicated by format. ![]() STRTODATE () returns a DATETIME value if the format string contains both date and time parts, or a DATE or TIME value if the string contains only date or time parts. The language for the month names, day names, etc are determined by the lc_time_names system variable. It takes a string str and a format string format. We can combine them, so that we get the time and date: SELECT DATE_FORMAT(' 10:30:45', '%r %W, %D %M %Y') Here it is again, but this time using %r to return the time returned in 12 hour format: SELECT DATE_FORMAT(' 10:30:45', '%r') Where date is the date, format is the format string (see accepted format specifiers), and locale is an optional locale to use for the returned format. The syntax goes like this: DATE_FORMAT(date, format) It also accepts an optional third argument that allows you to specify the locale. It requires two arguments the date and the format string. ![]() This function can be useful for when working with functions that require a format string.In MariaDB, DATE_FORMAT() is a built-in date and time function that formats a date according to the given format string. In addition to the above individual format specifiers, you can use the GET_FORMAT() function to return the full format string, without needing to remember which format specifiers, and in which order, to include in the format string. Here’s an example of using some of the above format specifiers to provide a format string for the DATE_FORMAT() function: SELECT DATE_FORMAT(' 10:30:45', '%r %W, %D %M %Y') Used with %v.įor STR_TO_DATE(), skip all punctation STR_TO_DATE(),skip all alpha characters. Year with 4 digits when first day of the week is Monday. Year with 4 digits when first day of the week is Sunday. Used with %x.įull weekday name in current locale (Variable lc_time_names).ĭay of the week. ![]() Week number (01-53), when first day of the week is Monday. Week number (01-53), when first day of the week is Sunday. Week number (00-53), when first day of the week is Monday. Week number (00-53), when first day of the week is Sunday. Time in 12 hour format, followed by AM/ PM. (1st, 2nd, 3rd…).įull month name in current locale (Variable lc_time_names).ĪM/PM according to current locale (Variable lc_time_names). For example, Feb (when using en_US).ĭay with English suffix th, nd, st or rd. Short weekday name in current locale (Variable lc_time_names). Below is a full list of format specifiers that can be used in format strings with functions like DATE_FORMAT(), STR_TO_DATE(), and FROM_UNIXTIME() in MariaDB. ![]()
