Summary: in this tutorial, you will learn about the MySQL TIME data type and how to use temporal functions to manipulate time data effectively. MySQL uses the 'HH:MM:SS' format for querying and displaying a time value that represents a time of day, which is within 24 hours.

The date and time data types for representing temporal values are DATE, TIME, DATETIME, TIMESTAMP, and YEAR. Each temporal type has a range of valid values, as well as a “ zero ” value that may be used when you specify an invalid value that MySQL cannot represent.

MySQL uses the ISO 8601 format to store the values in the following formats: DATE YYYY-MM-DD; TIME HH:MM:SS; TIMESTAMP YYYY-MM-DD HH:MM:SS; YEAR YYYY; Datetime compared to Timestamp

Jan 26, 2024 · DATE and TIME are foundational data types in database management systems like MySQL 8, essential for dealing with temporal data. Understanding how to manipulate and store these data types is critical for many applications, from scheduling systems to …

Here is an example that uses date functions. The following query selects all rows with a date_col value from within the last 30 days: . mysql> SELECT something FROM tbl_name-> WHERE DATE_SUB(CURDATE(),INTERVAL 30 DAY) <= date_col;. The query also selects rows with dates that lie in the future.

To define a column that includes a fractional seconds part, use the syntax type_name(fsp), where type_name is TIME, DATETIME, or TIMESTAMP, and fsp is the fractional seconds precision. For example: CREATE TABLE t1 (t TIME(3), dt DATETIME(6), ts TIMESTAMP(0));

Temporal data types that MySQL supports are as follows: The TIME data type can express the time of day or duration, and has a range of ‘-838:59:59’ to ‘838:59:59’. MySQL displays TIME values in ‘HH:MM:SS’ format, but TIME columns can be assigned using either strings or numbers.
