Question

I have a timestamp column. Say I want to get the rows where the day number in the year is < 50

Where Jan 1 = 1 and Dec 31 = 366

So the function is not year specific, I want to get the results between a day range e.g. 50 and 100 for all years.

Example

Timestamp

1. 2012-02-01
2. 2011-02-01
3. 2012-04-01

So retrieving those results where DAY < 50 would return results: 1 and 2 but NOT 3.

Answer 1

Try this:

  SELECT * FROM TableA 
  WHERE  DAYOFYEAR(DateCol) < 50 -- for < 50



SELECT * FROM TableA 
WHERE  DAYOFYEAR(DateCol) between 50 and 100 --between a day range e.g. 50 and 100
