MS SQL Server SQL Server 2008 Get Previous Values
You're next requirement is to do a calculation on each row with the previous row. Since the first 12 rows are static (and I presume not calculated) then we don't have to ask "what about the first row".

The row with DepartmentID=10 was updated as indicated by the value “U” in the SYS_CHANGE_OPERATION column. The row with DepartmentID=17 was inserted as indicated by the value “I” in the SYS_CHANGE_OPERATION column.

- In SQL Server 2008 and later you can turn on the Change Data Capture feature so that you can retrieve information about the row insertion order. In earlier versions that information is not exposed
- UNPIVOT is another relational operator in SQL Server that performs almost the reverse operation of PIVOT, by rotating column values into rows values. Let me demonstrate this with an example; lets create a table with pivoted data from the previous query with the script below. The image below shows data of the newly created table with pivoted data.
- We can recover deleted rows if we know the time when data is deleted We can achieve this goal using LSN ( Log Sequence Numbers ). As per Microsoft, “Every record in the SQL Server transaction log is uniquely identified by a log sequence number (LSN)".
- The Quirky Update method of updating column values using information from previous rows held in variables goes back to the earliest days of SQL Server, and was inherited from Sybase. While the Quirky Update will still work in SQL 2012, the window frame option of the window functions now offers us a much safer, set-based and standards-compliant way of doing it.
