SDU Tools: Seconds to Duration in T-SQL

There are a few places in T-SQL where instead of a time value, you need to work with a duration.

An example is if I want to sleep for a short period. In T-SQL, we can do that with the WAITFOR statement, used like this:

This command would cause SQL Server to wait for 10 minutes. One of the challenges though, is how do I create this duration string in a programmatic way? For example, how do I create the string '00:02:00' if I'm starting with a value of 120 seconds?

One of our free SDU Tools for developers and DBAs does just this. You can see it being used in the main image above.

SecondsToDuration converts a number of seconds to a SQL Server duration string (similar to programming identifiers). Note that the value must be less than 24 hours (between 0 and 86399) otherwise the return value is NULL.

You can use it directly from our toolkit or use it as an example of how to write the function.
