Turn: SQL Server to take the date and time part

The original text is reproduced from: http://www.cnblogs.com/weiqt/articles/2040800.html

The following is the reproduced content:

In this article, the date obtained by GetDate() consists of two parts, which are today's date and the current time: Select GetDate()
Use DateName() to get the corresponding year, month, and day, and then concatenate them That 's it:
Select Datename(year,GetDate())+'-'+Datename(month,GetDate())+'-'+Datename(day,GetDate())

In addition, DateName() can also get the hour, Time, second, day of week, week, respectively:
Select Datename(hour,GetDate())
Select Datename(minute,GetDate())
Select Datename(second,GetDate())
Select Datename(weekDay,GetDate())
Select Datename(week,GetDate())

The default format of the date type DateTime in SQL is yyyy-mm-dd hh:mi:ss: mmm, but in most cases we only want to get the date part, not the following time. In the previous article, I mentioned the use of the Datename() function to intercept and splice out dates that do not contain time parts. Now let's talk about a method, which makes it easier to get dates that do not contain time!

Use the Convert() function: select convert(char(10),GetDate(),120) as Date

* The third parameter is used to set the display style of date type data. The parameters of several styles are described below:
100 mm dd yyyy
101 mm/dd/yyyy
102   yyyy.mm.dd
103   dd/mm/yyyy
106   dd mm yyyy
108   hh:mi:ss(时间)
111   yyyy/mm/dd
112   yyyymmdd
120   yyyy-mm-dd
