Question

Suppose i have a table with columns: Approved, Joining_Date, Period.

Approve-String, Joining_Date-DateTime, Period-Integer.
Now I want to update the Approved column value to yes if the difference between today’s date and the Joining_Date column is greater than Period column. How can this be accomplished in a single query? Something like:

"UPDATE table_name SET Approved='Yes' WHERE (SYSDATE-Joining_Date>Period)"

I am using ASP.NET 4 and MS-SQL 2008 Express in VS 2010. Thanks in advance!!!

Answer 1

Assuming Period is in days:

UPDATE table_name SET Approved='Yes' 
WHERE DATEDIFF(DAY,Joining_Date, GETDATE()) > Period
