Year | Day | CreatedDate.

I want to update CreatedDate column, so day part like CreatedDate=Day and year part in CreatedDate=Year.

I tried with datepart function in update statement but wasn’t succesful.How can I do it?

Answer 1

Try something like this:

UPDATE
   YourTable
SET
   CreatedDate = DateAdd(year, [Year] - DatePart(year, CreatedDate), 
      DateAdd(day, [Day] - DatePart(day, CreatedDate), CreatedDate))
