In this video we will discuss DATEFROMPARTS function in SQL Server
DATEFROMPARTS function
Example : All the function arguments have valid values, so DATEFROMPARTS returns the expected date

In this video we will discuss DATEFROMPARTS function in SQL Server
DATEFROMPARTS function
- Introduced in SQL Server 2012
- Returns a date value for the specified year, month, and day
- The data type of all the 3 parameters (year, month, and day) is integer
- If invalid argument values are specified, the function returns an error
- If any of the arguments are NULL, the function returns null
