                  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.

                    We hit a similar problem with OPENJSON, Erik. Both your reproduction and ours appear to be fixed in the current private preview of vNext. Paul's reproduction still hits the intra-query deadlock, however.

                              Object Explorer doesn’t populate the entire tree in memory, unlike visual studio’s solution explorer. It wouldn’t know if database “MyDatabase” existed until you expanded the Databases node.
                              There are third party plugins that provide this type of functionality, I believe, by downloading a bunch of data in the background and exposing a search.

                                  <=-=Feb 1 2008 7:18PM=-=>

                                  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…

                                          I’m the first to post a useful comment. This must make me special.

                                          Seriously though, this would be an excellent solution to having to create a new “scratchdb” to hold my interim ETL data. This would be a major plus in simplifying design of a high performance app.

                                          In 2014, memory optimized tables, and delayed durability can be used help mitigate these Issues. However neither of this are always completely viable solutions. Brent’s proposed solution is likely the simplest way to achieve this with the least amount of unwanted impact. It is important to note that other platforms implement similar functionality as well. Notably Oracle.

                                          There are so many good things about this suggestion. I am amazed that SQL does not have the capability to turn off logging for certain tables that you define as no…

                                            It’s a shame that this was submitted as just a “suggestion”. It should actually be listed as a “bug” because there’s only a comparatively small set of use cases where enumeration of the result set of elements is not important.

                                            <=-=Mar 11 2016 12:47PM=-=>

                                            I agree that an order column is required; one example use case is where two lists are passed in, and ordinal positions in one list correspond to positions in the other.

                                            Please see the related suggestion: STRING_SPLIT needs “RemoveEmptyEntries” option, like String.Split in .NET ( https://connect.microsoft.com/SQLServer/feedback/details/2462002/ ).

                                            This kind of function is primarily needed for de-serializing previously serialized arrays of values of any type format-able as text.
                                            I therefore recommend to have the result set of this function work excellent with this use-case.

                                            With de-serialized arrays there is a need to…
