SQL Server Partioning or Ranking ?
Posted on 2015-01-09
Hi, i have a table called test and below is my sample data for an application id.
so basically I want get the count in Days since the last status has changed based on the start date per each application. So in this example, it has to be the difference in days between the first row and the fourth row because eventough the second row is showing as the last changed date after 27th october 2014, it still got the same status as 7 so the status has not really changes so the query should look at the next latest date when the status was changed which is 4th record .
Can anyone please give me that tsql code please ?
appid statusid startdate
