This is an incomplete summary of what's new with SQL Server 2012 as I discover them:
- Data Center edition will be moved into Enterprise Edition.
- Licensing will be based on the number of cores rather than the number of processors.
- A database-level sequence number, similar to identity within a table, will be available for use.
- Create the sequence under the Programmability section of the database in Object Explorer, or with SQL:
CREATE SEQUENCE DemoSequence
START WITH 1
INCREMENT BY 1;
- Assign the sequence to a field or variable with,
SELECT @seqvar=NEXT VALUE FOR dbo.DemoSequence
- Paging now acts more like MySQL (but why couldn't they just use LIMIT and be done with it?):
SELECT *
FROM Customers
ORDER BY CustomerID
OFFSET 10 ROWS -- I assume this is base 1, as opposed to LIMIT which is base 0.
FETCH NEXT 10 ROWS ONLY; -- So if I understand it right, this will return rows 11-20.
- Working with results from stored procedures was sometimes cumbersome. The new WITH RESULT SETS option makes EXECUTE work more like a common table expression, or SELECT INTO.
- Reporting services are being replaced with Power View, with the results being more graphically oriented as opposed to text or chart based.
- Power View reports can be exported directly to MS Word or Excel formats.
- Improved high availability features, termed "Always On."
- SQL Express LocalDB can be placed into a user directory and run without requiring Admin rights to the PC.
- There is the expected mix of overall performance, security, and capacity improvements.
