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…

      • 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

          <=-=Jan 10 2017 9:51AM=-=>

          @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…

          • 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.

              • Correctly escape predefined entities in deadlock XML

                If you create a table that has &, ", <, or > in the name, it's not correctly escaped in all instances of deadlock XML.

                This causes an error when trying to convert extended event/system health data to valid XML for analysis.

                • 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…

                  • 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…

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

                      I have a very strange issue happening that is causing Script Task code to clear out. I have been able to test on 2-3 different machines. We are running SSDT 15.4 preview. The steps to reproduce were as follows.

                      1. Create a script task inside of a foreach loop container. 2. Create a comment in the script task. 3. Change or add a variable mapping in the foreach. 4. Save package. 5. Open the script task and the comment will have vanished.

                      As my last attempt for success,I have upgraded to 15.5.1 and the problem still exists.

                      • 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.

                          • SET STATISTICS IO should also show schema name for tables

                            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.
                            Table 'Profile'. Scan count 3, logical reads 13, physical reads 1, read-ahead reads 342, lob logical reads 0,…

                            • Script Tasks losing code in SSDT 17.1 for Visual Studio 2015

                              I have an SSIS 2016 package with a number of For Each ADO Loops, each with a single script task, which are usually working fine.

                              However, every so often, a script task will suddenly 'forget' all the code within it. I'm presented with an empty task editor which has reset to C# (if using VB), and lost the ReadOnlyVariable names.
                              If I click Edit Script, I get a brand new script created in the editor. This can occur intermittently on reopening the package, or after editing _a different_ script task.

                              The same thing also occurs with both VB and C#…

                                I have had the exact same issue, intermittently whenever I open script tasks all my code seems to have vanished and all the “ReadOnlyVaraiables” and “ReadWriteVariables” have also disappeared. It happens for c# and VB script tasks. This is is extremely frustrating and is impossible to develop a project when code randomly keeps disappearing. I’m wondering if this is a bug with Visual Studio 14.0.23107.0 D14REL. Can anyone at Microsoft shed some light on this please?

                                Got the same problem. Seems like the Script Task is cleared when the project/Visual Studio i closed/shut down.

                                Same problem for me, too. Once the original code in Script Task was still present after reloading the solution. But after that they are gone, along with ReadOnly/ReadWriteVariables and ConnectionManagers. I’m using SSDT 14.0.61705.170 (which just came out) with VS 14.0.25431.01 update…

                                T-SQL Common Table Expression "Materialize" Option

                                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…

                                  Deadlock XML for column store indexes is missing several pieces of information about which objects were deadlocked in the resource-list section of the XML

                                  • Maintenance Plan Portability

                                    Maintenance Plans should be scriptable, deployable and maintainable without the need to manually create/update a plan on each server/instance. Current functionality requires the DBA to manually generate a SQL Maintenance Plan one at a time for each instance in the environment. Built in SQL Maintenance Plans should be scriptable, deployable and maintainable with TSQL or in some automated fashion that will allow deployment to large enterprise environments that do not require the use of a GUI.

                                    • "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.
