I've shown in recent posts how to extract components out of dates and times. You might also want the name of a month or a day, rather than just its number. The DATENAME() function does that.
In this query, I've asked for the name of the month that's part of the date 28th February 2019. So it returns:
An important concept here though is that this is based upon my regional settings. Mine currently are set to US English, to it returned February. But if I had different regional settings, it would display the name in whatever region I was configured to use. So if I had a French configuration that would come back with Février instead.
