How can I convert a week number to an actual date?

This is more of a solution to a question I had.

 

To start, I'll tell you what I'm working with. I have a string which is my week number named `Week` and it looks like this:

 

  • Week 1
  • Week 2
  • Week 3

I also have an integer of the four digit year (e.g. 2016) named `Year`.

 

From these I wanted to create a date recognized within Domo as a date. I built this within a Beastmode, but the code applies to SQL very closely:

 

(

 CASE

  WHEN `Year` = 2016

          THEN STR_TO_DATE(CONCAT('2016,',TRIM(RIGHT(`Week`,2)),',Sunday'),'%Y,%U,%W')

 END

)

 

The String to Date function does the converstion of a string with a known or specified format into a date. The Concat puts the string elements together. Trim removes the white space and Right takes the specified rightmost characters.  The Sunday in the code specifies that for my circumstance I want the date that begins with Sunday.

 

If your year was a string instead of an integer like mine the above code could be further simplified. 

 

I hope this helps you out!
