These include functions that perform date arithmetic or that map parts of dates to names. Functions that take temporal arguments accept values with fractional seconds.
Return values from temporal functions include fractional seconds as appropriate. When invoked with the days form of the second argument, MySQL treats it as an integer number of days to be added to expr. Time zones are specified as described in Section 5.
This function returns NULL if the arguments are invalid. For instructions, see Section 5. Returns the current time as a value in 'hh:mm:ss' or hhmmss format, depending on whether the function is used in string or numeric context. The value is expressed in the session time zone. If the fsp argument is given to specify a fractional seconds precision from 0 to 6, the return value includes a fractional seconds part of that many digits.
DATE expr. Extracts the date part of the date or datetime expression expr. Only the date parts of the values are used in the calculation. These functions perform date arithmetic.
The date argument specifies the starting date or datetime value. For more information about temporal interval syntax, including a full list of unit specifiers, the expected form of the expr argument for each unit value, and rules for operand interpretation in temporal arithmetic, see Temporal Intervals. Formats the date value according to the format string.
The specifiers shown in the following table may be used in the format string. Ranges for the month and day specifiers begin with zero due to the fact that MySQL permits the storing of incomplete dates such as ''.
The mode affects how week numbering occurs. DAY date. Returns the name of the weekday for date. Returns the day of the month for date , in the range 1 to 31 , or 0 for dates such as '' or '' that have a zero day part. These index values correspond to the ODBC standard.
Returns the day of the year for date , in the range 1 to For information on the unit argument, see Temporal Intervals. It is not intended for use with values that precede the advent of the Gregorian calendar The value returned is expressed using the session time zone.
Clients can set the session time zone as described in Section 5. Returns a format string. HOUR time. Returns the hour for time. The range of the return value is 0 to 23 for time-of-day values. Takes a date or datetime value and returns the corresponding value for the last day of the month.
Returns NULL if the argument is invalid. Returns a date, given year and day-of-year values. Returns a time value calculated from the hour , minute , and second arguments. The second argument can have a fractional part. Returns the microseconds from the time or datetime expression expr as a number in the range from 0 to Returns the minute for time , in the range 0 to MONTH date.
Returns the month for date , in the range 1 to 12 for January to December, or 0 for dates such as '' or '' that have a zero month part.
Returns the full name of the month for date. The column or one of the columns to be updated. It must be the name of a column in the referenced table or view. You can retrieve the column values into variables or host variables, or into collections or host arrays. The old column values are used on the right side of the equal sign. The subquery must return exactly one row and one column. Choose your interests Get the latest news, expert insights and market research, sent straight to your inbox.
