SQL Server 2012 FORMAT Function vs. CONVERT Function
One of the most frequently asked questions in SQL Server forums is how to format a datetime value or column into a specific date format.Here's a summary of the different date formats that come standard in SQL Server as part of the CONVERT function and the corresponding syntax using the new SQL Server 2012 FORMAT string function.
It is worth to note that the outputs of these date formats are of VARCHAR data types already and not of DATETIME data type.
