SQL Equivalent of Oracle OVER (PARTITION BY ORDER BY RANGE UNBOUNDED PRECEDING)
I'm in the process of converting Oracle materialized view to SQL indexed view. This view has following analytical functions in written in Oracle:
……
SUM(Vacation_Hrs) OVER(PARTITION BY Emp_ID ORDER BY Pay_Period RANGE UNBOUNDED PRECEDING) As ‘Running Total of Vac_Hrs’,
SUM(SickLeave_Hrs) OVER(PARTITION BY Emp_ID ORDER BY Pay_Period RANGE UNBOUNDED PRECEDING) As ‘Running Total of SickLeave_Hrs’,
……. Etc.
I have tried to use the T-SQL’s OVER() function but it doesn’t have the feature like oracle does. I see there are couple of other postings in the internet, SQL Server Magazine. But none of them are as clean as the Oracle’s one. I appreciate any idea of solving this problem.
Thanks.

For those of us who are not Oracle users (anymore), you'll need to give an example of a data set and what results set you expect the function to create. Follow the example in the thread below for proper posting.

It's 2015. Just had to say, thank you for not even trying to answer the question. You are technically correct; however, very unhelpful to those who might stumble across this page in the future, struggling to find an answer.

What version of SQL Server are you using? Sounds like you may be using SQL Server 2008 and the features you are looking for were released in SQL Server 2012.

Actually...asking for detailed information is often the first step in being able to provide a relevant answer. For the record, the original post is 6 years old. I am sort of surprised you found this old forum in a search. Being that as it may, in sql 2012 the windowing functions have been extended to do the same thing and the syntax is pretty much identical. Prior to 2012 it is more difficult.

Here is the BOL (books online) page about the OVER clause. https://msdn.microsoft.com/en-us/library/ms189461.aspx

Quick question, which version of SQL Server are you using? As Lynn said, the extended analytical functionality was introduced in SQL Server 2012, slightly later than in ORA. IIRC this functionality wasn't even fully defined when SQL Server 2005 was released 😉

It's six years old but still appears in a search engine query result. If the information/thread is incomplete or not marked as resolved and it's this old, it should be removed.

Why should it be removed? It still serves a purpose.
