MariaDB supports a large list of locales that are used by functions such as DAYNAME(), MONTHNAME() and DATE_FORMAT().
While these locales are available to MariaDB, by default they’re not loaded into any of the system tables, so you can’t run a query to retrieve them.
However, MariaDB provides a plugin that does load these into a table. Once the plugin has been installed, you can query that table to return the locales available in MariaDB.
Below is a full list of date and time locales available in MariaDB.
In MariaDB, DATE_FORMAT() is a built-in date and time function that formats a date according to the given format string.
It requires two arguments; the date and the format string. It also accepts an optional third argument that allows you to specify the locale.
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.
In MariaDB, DATEDIFF() is a built-in date and time function that returns the difference, in days, between two dates.
It accepts two arguments, both of which are date or datetime expressions. It then subtracts the second date from the first.
In MariaDB, DATE() is a built-in date and time function that extracts the date part of a date or datetime expression.
You pass the date/datetime expression as an argument when calling the function.
In MariaDB, LOCALTIMESTAMP and LOCALTIMESTAMP() are synonyms for NOW().
The NOW() function is a built-in date and time function that returns the current date and time.
The time is returned in either 'YYYY-MM-DD HH:MM:SS' or YYYYMMDDHHMMSS.uuuuuu format, depending on whether the function is being used in a string or numeric context.
In MariaDB, LOCALTIME and LOCALTIME() are synonyms for NOW().
The NOW() function is a built-in date and time function that returns the current date and time.
The time is returned in either 'YYYY-MM-DD HH:MM:SS' or YYYYMMDDHHMMSS.uuuuuu format, depending on whether the function is being used in a string or numeric context.
In MariaDB, CURRENT_TIMESTAMP and CURRENT_TIMESTAMP() are synonyms for NOW().
The NOW() function is a built-in date and time function that returns the current date and time.
The time is returned in either 'YYYY-MM-DD HH:MM:SS' or YYYYMMDDHHMMSS.uuuuuu format, depending on whether the function is being used in a string or numeric context.
In MariaDB, NOW() is a built-in date and time function that returns the current date and time.
The return value is returned in 'YYYY-MM-DD HH:MM:SS' or YYYYMMDDHHMMSS.uuuuuu format, depending on whether the function is used in a string or numeric context.
The return value is expressed in the current time zone.
You also have the option of specifying the microsecond precision.
