SQL Server

Microsoft SQL Server 2017 powers your entire data estate by supporting structured and unstructured data sources. It builds on previous versions of SQL Server, which have been industry leading for four years in a row and a leader in TPC-E. It scales to petabytes of data and allows customers to process big data through PolyBase using T-SQL over any data. SQL Server has also been the least vulnerable database during the last seven years. SQL Server 2017 brings data insights with business intelligence capabilities that provide analytics at a fraction of the cost on any device along with advanced analytics with support for R and Python.

More details about SQL Server are available in the SQL Server documentation.
If you have a technical issue, please open a post on the developer forums through Stack Overflow or MSDN.

  1. binary or string data would be truncated => error message enhancments

    if you have that error (in production), it's not obvious to see which column or row this error comes from, and how to locate it exactly.
    it's even more complicated if it's coming from a trigger, for example, and not the original insert/update.

    I have seen that oracle meanwhile gives clear information which column the error is raising, which actual data length was passed, and the column's max size.

    • Add FOR CSV to facilitate CSV export

      We have FOR XML and FOR JSON. But it is not uncommon that people want to produce CSV files. This can be done with BCP, but it is not straightforward not the least if you want to add headers. And if you only want fields to be quoted when needed, BCP is not really what you are looking for. SSIS is also an alternative, but SSIS does not always fit in.
      Thus, it would be handy if there was a an option like FOR CSV, with a syntax like:
      FOR CSV [, HEADERS] [,DELIMITER(',')] [, QUOTE('"')]

      HEADERS would mean that…

      • Add a Keyboard Shortcut that Executes the Statement where the Cursor is placed

        Having to select statements by clicking and holding the mouse is just bad ergonomics. Request to have a keyboard shortcut which runs the current sql statement. The current sql statement is defined based on where the cursor is placed. For example, proposed shortcut runs only runs a single sql statement to the next semicolon. This shortcut would be an equivalent to Oracle's SQL developer's ctrl + enter shortcut. Note that this is probably the most used shortcut in SQL Developer and not having an equivalent on SQL Server Management Studio is disappointing. I know that not everyone ends their statements…

        • Provide a mechanism for columns to automatically update themselves

          It is extremely common for databases to contain columns like "UpdatedDate," "UpdatedBy," etc. These columns work based on a trust model: As a database designer, I must trust that all of my downstream consumers will follow the intended rules, remembering to update the columns every single time any transaction occurs. And of course I have to trust that they'll put in the correct values. The only alternative to trust is to put ugly and potentially slow triggers in place to make sure everything happened the right way.

          This situation needs to change, and this is especially prevalent now, thanks to…

            This is similar to my feedback located here: https://connect.microsoft.com/SQLServer/feedback/details/2769130/sql-2016-temporal-tables-with-triggers. The solution I suggest is similar to this, and could be used in many different cases developing using SQL server.

            I would love this too. The issue is that many/most applications don’t use Windows Auth in the connection to SQL Server (connection pooling issues, etc), so SQL can’t get the User information

            @Sanford

            Just to clarify, I am not asking for an “automatically store user name” feature. I’m asking for “automatically store whatever I want, based on whatever expression I provide.” So the fact that the user name may or may not be available is not really relevant.

            That said, there are plenty of workarounds for various situations. I imagine that if you’re using a shared connection, you can get some notion of “user” some other…

          • Dark Theme for SQL Server Management Studio 2017 (SSMS 2017)

            Dark Theme works well in Visual Studio and should be included in SSMS. It helps reduce eye strain after long periods of development and debugging.

              • Easier identification of Implicit Transactions

                Lots of ORMs let developers choose to enable implicit transactions, but there's no easy way to identity them without:

                1. Running Profiler
                2. Using the existing_connection XE session

                Though it's a SET option, it's not included in the plan XML where SET options are identified, nor is it in sys.dm_exec_plan_attributes or sys.query_context_settings.

                Using implicit transactions haphazardly can lead to some pretty nasty blocking chains. It should be much easier to identify when they're in use.

                Thanks!

                • Enable Query Store for collection on a read-only replica in an Availability Group

                  Currently, Query Store can only be enabled for the read-write database in Availability Group. As many customers issue queries against the read-only replicas, capturing query and performance metrics for those queries would be beneficial for understanding the workload, troubleshooting performance issues, etc.

                  • Provide XEvents target directly into SQL Server table

                    Provide a way to directly write XEvent output directly into a SQL Server database table in a same or different instance and same or different database.

                    The goal being to be able to not have any events missed but have the entire stream captured to the table and also provide header information for when the capture table was created for easier management and deletion. Ideally there should be a purge task that could be activated to clean out such captures after X days.

                    XEvents is a great and powerful tool.
                    Customers should have an easier way to get it directly…

                    • In SQL Server Always oafter a failover, SQL Server keep the connections open without killing any session

                      Hi Msft Team!
                      I want to suggest one improvement to your sql server always on feature. Normally, once we perform failovers we need to ask app teams for maintenance windows... or in worst cases ,if this happens automatically, we need to discover the RCA of this because all the application or users connections had been terminated. Also many times that we had automatic failovers or perform failovers with long executions happening the secondary instance turned into recovery state because it was waiting for this session to finish to synchronize again. So, is it possible to add the capability for failovers…

                        • Use column aliases directly in SELECT clause

                          It would be nice if queries like this were possible:

                          SELECT
                          A AS B
                          ,C AS D
                          ,D-B AS E
                          FROM table

                          In other words, use column directly in the SELECT clause where they are defined. Other database vendors have implemented this, so I assume it's not rocket science.

                          Right now, we have to use subqueries just to define an extra calculation.

                            I have run into a couple performance and results issues using Common Table Expressions (CTEs).

                            The first case is where I coded a data retrieval as a single, large query with a CTE that is referenced multiple times in the query. The CTE has an expensive query. I was able to determine, via execution plans, etc., that the results of the CTE were being recalculated multiple times, resulting in slow execution. I rewrote the data retrieval as multiple steps where the query of the CTE was first executed into a table variable, and I…

                            • MAX/MIN as NON-aggregate function

                              Please add the GREATEST/LEAST functions, just like in PostgreSQL/Oracle (with the same name for syntax-compatibility).
                              SQL-Server lacks functions for MAX/MIN as NON-aggregate function.
                              e.g. When I need the MAXIMUM of two values, or the minimum of two values (in columns, not rows).
                              When the value is a lengthy expression, it sucks having to write it in a case expression.
                              Also, the case-expression doesn't work for N > 2, and having to put it into a subselect-value-statement to use the aggregate functions as workaround affects readability severely (and thus maintainability).
                              Also, since SQL-server user-defined functions are damn slow, and on top…

                                would like it very much, particularly since you already have the CONCAT / GREATEST() a variable number of paramenters and does something with it…

                                GREATEST / LEAST functions would be fantastic addition.

                                The workarounds using CROSS APPLY or CASE expressions are difficult to manage and read. I’d love to see these implemented.

                                When you use schemas in your database, and you have the same table names in multiple schemas, it is not clear, which schema the table belongs too in the output of the SET STATISTICS IO. E.g. a table called Profile, or configuration in different schema is very common at our databases

                                Today the output is just
                                Table 'Profile'. Scan count 1, logical reads 123, physical reads 1, read-ahead reads 121, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

                                • "Call Stack"

                                  Provide DMV to provide the call stack of stored procedures, triggers, CLR functions etc prefferable in JSON format so it is parsable.

                                  As Erland Sommarskog says this is available but only in the "event Blocked Process Report:

                                  <executionStack>
                                  <frame line="17" stmtstart="1332" stmtend="2906" sqlhandle="0x03000d00399f00558c840601a29800000100000000000000"/>
                                  <frame line="1" sqlhandle="0x01000d00638e300f302e10ac000000000000000000000000"/>
                                  </executionStack>

                                  That is, here the call stack is available. Through the sqlhandle it is possible to retrieve
                                  the objectids of the calling procedures.

                                  If if it's available this way, it can't be too difficult to expose this in a DMV. Only exposing the
                                  sqlhandle would not match with my observation with permissions above, but…

                                  • Replace the import wizard with Power Query

                                    Instead of using the outdated import wizard (not the new one that was released recently in SSMS), a new one should be created that leverages the Power Query engine (aka the M language) to import data into SQL Server.

                                    • Please create a redistributable command-line equivalent for SSMS -> Extended Events -> Export

                                      We've created a .NET C# based export for XEL to CSV using QueryableXEventData but it takes 4 minutes to export a 1GB file. In SSMS, clicking Extended Events -> Export -> CSV takes 45 seconds for the same file.

                                      Unfortunately, interative SSMS is required, so the process cannot be automated. Please create a command-line executable so we can automate the export at the delicious speeds of SSMS.

                                      Also, if the NULL can be removed from output in both SSMS and the command line tool, that would be far better.

                                      • SQL Agent Job Chaining

                                        It would be a great feature to make SQL Agent Jobs hierarchical so that one (or more) job(s) can be dependent on another job allowing SQL Agent Jobs to be chained together.

                                        • The Scalar Expression function would speed performance while keeping the benefits of functions.

                                          SQL Server scalar User-Defined Functions (UDFs) have a performance problem that could be solved with an enhancement to the SQL Server database engine. Because SQL Server must execute each function on every row, using any function incurs a cursor like performance penalty.� However, since many UDFs are simple, they can often be converted to a single expression.� This suggestion proposes that a new type of UDF, the Scalar Expression UDF, be added to SQL Server.� Doing so would often eliminate the performance penalty paid when using scalar UDFs and allow them to be used more widely.� Using UDFs has the…

                                            ANS SQL 99 actualy defines a syntax (section 11.49) for function definition that can be used for an inline scalar function (body consisting of a single RETURN statement) – inlining being an implementation rather than a definitional issue. There are other database products (e.g. IBM DB2 UDB) that already support this, so going the ANS way would assist portability.

                                            The enhancement is clearly necessary.

                                            <=-=Oct 11 2007 8:45AM=-=>

                                            In other programming languages, this might be a macro expansion, where an include file contains the macro, which expands into inline code at compile time. (I believe that this was discussed as a possibility in the very early days of Yukon.) In any case, however implemented, Inline Scalar UDF would be a major improvement over the speed-bump that exists now.

                                            I was going to post this myself, but happily add my vote to the existing…
