    Benefits:
    Improved Readability, therefore Maintainablity, therefore reduced manpower $ and time expenditure.

    I definitely see the value of this. Thanks for proposing it. We’ll try to squeeze it in to SQL Server 2008 but things are really tight in terms of room for changes like this. It has to compete with many other things, including a bunch that have a larger impact on query performance, or that don’t have an easy workaround. This issue has a workaround, though it is not pretty and programmability would be enhanced a lot with the proposed enhancement. I’ll see what I can do.

    Best regards,
    Eric

    Things do not look good for this enhancement for Katmai. It probably will not make it into the release. We’ll make a final assessment in a couple of weeks. Before we can consider this,…

    I particularly like his suggestion for a IS & IS NOT syntax

    Thanks for the valuable suggestion.

    This seems more like adding the sequence support which we’re seriously considering for the next major release.

    Meanwhile, would using identity column help?

    <=-=Feb 2 2008 2:11AM=-=>

    It does not seem that you understood the request. This definitely has nothing to do with
    IDENTITY. I am less versed about sequences, but I don’t think they will cut it either. If you think
    it does, maybe you could provide an example? Take this problem: For the Orders table in
    Northwind, write a query that lists the number of orders for all days in 1997. The result set should
    include all 365 days, and list zero for days without a number.

    This is a typical problem where you need a table of of numbers (or dates). While it’s easy to
    create such a table, I argue in this request that…

    Just wanted to add that both Oracle and DB2 seem to support this feature:

    http://docs.oracle.com/database/122/SQLRF/LAG.htm#SQLRF00652
    https://www.ibm.com/support/knowledgecenter/en/SSGU8G_12.1.0/com.ibm.sqls.doc/ids_sqs_1513.htm

    Cheers,
    Itzik

    <=-=Apr 16 2017 10:08PM=-=>

    That last IBM link was for Informix!

    The DB2 link is https://www.ibm.com/support/knowledgecenter/SSEPGG_11.1.0/com.ibm.db2.luw.sql.ref.doc/doc/r0023461.html

    <=-=Jul 4 2017 3:30AM=-=>

    Thanks for reporting this request.
    It is in our backlog, and we have planned to do something like this, but we cannot confirm when it would be completed.

    Jovan

    <=-=Jul 10 2017 11:54AM=-=>

    Thanks, Jovan; good to hear.

    This feature vastly simplifies development of certain types of applications. Would be interesting at least know if microsoft has some intention to implement it.

    <=-=Jul 27 2016 5:19PM=-=>

    A fully compliant implementation to ansi sql 2011 would nice too.

    <=-=Jul 28 2016 1:01AM=-=>

    I would also like to see bitemporal support added, it would be most useful!

    <=-=Mar 7 2017 11:54AM=-=>

    This feature would really help people trying to migrate their DBs from DB2 or Oracle to SQL Server that much easier.

    This would definitely be a good build. I walked through an initial investigation of clustered columnstore on one of our data sets, and the number of reads was reduced by about 80% for some queries in the workload once I started paying careful attention to segments and loading data in a single-threaded manner to optimize segment elimination. However, this results in slower loading of data, and it would be great to be able to create columnstore indexes in order for segment elimination.

    Having an optional ORDER BY clause for the columnstore initial creation, removing the need to first create a clustered index in order to control order and allowing parallelism without breaking order, would be particularly powerful.

    <=-=Jul 3 2014 10:30AM=-=>

    Neugebauer: thanks. you identified the issue correctly. This is something we are actively looking. One question
    (1) once the index is build, the…
