SQL 201-Formatting Dates in Microsoft SQL

Posted on by slowder

One of the more frequent questions I get for SQL Server is how to format a DATETIME 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. Following the standard date formats are some extended date formats that are often requested by SQL Server developers. It is worth to note that the outputs of these conversions are VARCHAR and not DATETIME. With this in mind, any date comparisons performed after the DATETIME value has been formatted are using the VARCHAR value of the date and time and not its original DATETIME value.
