The DATEPART function in SQL is used to extract a specified part of a date or time expression, such as year, month, day, hour, minute, etc. Here is the syntax:

DATEPART(datepart, date)

Among them, the datepart parameter specifies the part to extract, which can be one of the following values:

year: the period of time equal to the time it takes the earth to make one complete revolution around the sun
quarter: a period of three months
month: time period within a year
dayofyear: the number of the day in the year
date
week: what week of the year it is
What day of the week is it?
hour: a unit of time equal to 60 minutes
minute: a unit of time equal to 60 seconds.
second: a unit of time equal to 1/60th of a minute

The date parameter is a date and time expression that can be a combination of date, time, or date and time. The DATEPART function will return the integer value for the specified part.
