This video is a quick overview of using the SQL Server Datetime function.
The datetime is actually made up of two different pieces:
This can be demonstrated using the SQL Cast function on a string to convert it to a datetime.
Here is some SQL for the Date portion:
select cast('20121019' as datetime)
Here is some SQL for the Time portion:
select cast('10:05:00' as datetime)
Now, you can also simply use the built-in getdate() function to bring back the current system time.
And finally, I want to bring back a datetime from an actual table.
In this case, we will use the employee table from the SQL Training Online Simple DB:
select hire_date from employee
If we want to convert the result to a more formatted string, we will use the TSQL CONVERT function:
In this example, we are converting from a datetime to a varchar (string). The result will be in the format of 104.
To translate 104 to a datetime format, you will want to look at the MSDN Documentation.
And, that is how you use the Datetime SQL.
