Seeing “USE AdventureWorks2008R2″ makes me think you’re using SQL 2008R2. LEAD/LAG is only available in SQL 2012

Msg 195, Level 15, State 10, Line 2
‘LEAD’ is not a recognized built-in function name.

Sorry this is the error I am getting when I am trying to execute the below query.

USE AdventureWorks2008R2
GO
SELECT s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty,
LEAD(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID
) LeadValue,
LAG(SalesOrderDetailID) OVER (ORDER BY SalesOrderDetailID
) LagValue
FROM Sales.SalesOrderDetail s
WHERE SalesOrderID IN (43670, 43669, 43667, 43663)
ORDER BY s.SalesOrderID,s.SalesOrderDetailID,s.OrderQty
GO

Thanks
Anil

I have a table that has 1-24 hours of sales information, Table has date, store name, store location, Intrvl_1, sales $$. Like this I have 24 rows for one day for one store, I need those store where there was a consistent sales $$ (or 5% deviation is OK) between Intrvl_9 to Intrvl_15.
Any help?

I have got some doubt in conversion of varbinary to varchar. The problem is, I am actually replicating a pdf file(saved as varbinary) from one db to another db through dynamic query but I am getting an error varbinary datatype is incompatible with add operator.Also explicitly mentioning convert varchar() gives me a unidentified file type!! Any possible solution for this problem?

This is tech from the early 2000s (Oraclee, DB2) that was finally added to ansi sql in 2003, and it merits an article in 2012? This is literally ten year old tech.
