Problem
SQL Server 2008 and earlier versions used the CONVERT functions to handle date formatting. In this tip, Date and Time Conversions Using SQL Server, we have a list of the available examples on how to use the CONVERT function to handle different date formats. As you may notice, this function is not very flexible and we have limited date formats. In SQL Server 2012 and future versions, a new function FORMAT has been introduced which is much easier to use. This article shows different examples of using this new function.
Solution
SQL Server 2012 includes a new function to handle formatting dates. This function is similar to Oracle's to_date function. Many Oracle DBAs complained about the CONVERT function and its poor flexibility and now we have a new way to format dates in SQL Server.
With the FORMAT function we do not need to know the format number, we can just specify the format that we want and we get that format.
The syntax of the FORMAT function is the following:
FORMAT (Value,format[,culture]) GO
FORMAT Samples
Let's start with an example:
select FORMAT (getdate(), 'dd-MM-yy') as date GO
The format is day-month-year. The output will be: 07-03-12.
Let's try another one:
select FORMAT (getdate(), 'hh:mm:ss') as time GO
The format is hours:minutes:seconds. The output will be: 02:48:42.
Culture Option
Another option for this function is the culture. With the culture option you can obtain regional formatting.
For example the hour in USA format is:
select FORMAT (getdate(), 'd', 'en-us') as date GO
The output is: 3/7/2012
Here is another example where we will use the Spanish culture in Bolivia (es-bo):
select FORMAT (getdate(), 'd', 'es-bo') as date GO
The output is: 07/03/2012 which is different because each country has its own format. In Bolivia the format is day, month, year where in the United States it is month, day, year.
For a complete list of values for cultures, tale a look at this article language codes.
