MariaDB 10.1.2 introduced the -mysql56-temporal-format option, on by default, which allows MariaDB to store DATETMEs using the same low-level format MySQL 5.6 uses. For details, see date and time literals.ĭATETIME columns also accept CURRENT_TIMESTAMP as the default value.
MariaDB displays DATETIME values in ' YYYY-MM-DD HH:MM:SS.ffffff' format, butĪllows assignment of values to DATETIME columns using either strings or A total of 3 bytes would need extra for the storage of fractions.Syntax DATETIME Fraction (3, 4) takes 2 bytes, and fraction (5, 6) takes 3 bytes of storage. Considering precision and wanting to keep the precision fraction (0) takes 0 storage bytes.
We can also store the fraction, but holding the fraction would increase the storage. Datetime stores the data in year, month, date, hour, minutes, and seconds. If we want to store a value of date that contains both date and time, then we use the Datetime format. If we check the data for the “Date_time,” we can see that the storage taken for the column is 7 bytes as it saves the precision fraction of (3, 4). Now let us insert into the table with the current date: INSERT INTO TEST_DT1 VALUES (11,' 09:22:08:123')
Now let us insert into the table with the current date: INSERT INTO TEST_DT VALUES (1,' 09:22:08:123') Given below is the format of the above data: If we see the value of “ Date_time “ value: Here we check the data for the “order_date.” We could see that the storage taken for the column is 7 bytes as it saves the precision fraction of (3, 4). Let us insert the data into the table: INSERT INTO TEST_DATETIME1 VALUES ('O1',' 12:00:00') Now let us create a table with a column data type as datetime and get the result.
