In Excel, you can combine Date and Time together by using the + . However, you cannot do this in SQL Server:
SELECT @Dat + @Tim
This results in an error.
In this video, we'll look at how to CAST or CONVERT the values into datetime, and then we can use the + operator to add them together.
However, what if you want to have it as a DateTime2? You cannot use the + operator then. Instead, you can use CAST (or CONVERT), DATEDIFF and DATEADD.
In this video, we'll see how you can do both of these options.
If you would like to do this as a Practice Activity, then here is the code to start with:
declare @Dat as date = '2024-01-31'
declare @Tim as time = '17:14:00'
