..and in the cloudsWhen I first saw early builds of SQL Server 2017, one of the features that caught my eye immediately was Automatic Tuning with an option called Automatic Plan Correction. SQL Server 2017 was released in October of 2017 right on the heels of one of my favorites releases, SQL Server 2016. In SQL Server 2016, we brought to the product a new feature called Query Store. When Query Store is enabled for a database via ALTER DATABASE, the SQL Server engine will start collecting query performance telemetry in memory and system tables in the database. No longer do you need to poll Dynamic Management Views and store them into your own tables. This performance telemetry is collected by the SQL Server engine itself when queries are compiled and executed.
Like many features we build into SQL Server, you can use T-SQL queries to find out the details of this performance data through a series of catalog views. Query store opens up all types of cool performance insights and we have documented some of the key usage scenarios. One of these scenarios is called a query plan regression (also known as plan choice regressions).
Imagine this scenario. You

Microsoft is pleased to announce that the Analytics Platform System (APS) appliance update 7 (AU7) is now generally available. APS is Microsofts scale-out Massively Parallel Processing (MPP) system based on SQL Server for data warehouse specific workloads on-premises.
Customers will get significantly improved query performance and enhanced security features with this release. APS AU7 builds on appliance update 6 (APS 2016) release as a foundation. Upgrading to APS appliance update 6 is a prerequisite to upgrade to appliance update 7.
APS AU7 now provides the ability to automatically create statistics and update of existing outdated statistics for improved query optimization. APS AU7 also adds support for setting multiple variables from a single select statement reducing the number of redundant round trips to the server and improving overall query and ETL performance time. Other T-SQL features include HASH and ORDER GROUP query hints to provide more control over improving query execution plans.
APS AU7 also includes latest firmware and drivers along with the hardware and software patch to address the Spectre/Meltdown vulnerability from our hardware partners.
Customers already on APS2016 will experience an enhanced upgrade process to APS AU7 allowing a shorter maintenance window with

A few weeks ago, developers from around the world gathered for the Microsoft Build Conference. It was an amazing display of Microsofts products and cloud services to meet the needs of all types of applications. I missed the //build event this year because I found myself in San Francisco at the Red Hat Summit 2018. I cant even imagine five years ago someone telling me I would represent Microsoft and SQL Server at an open-source based event.
Travis Wright, Jamie Reding, and I travelled to the event to speak and show amazing demos of SQL Server running on Red Hat Enterprise Linux (RHEL) and OpenShift. We were part of the Microsoft team attending the event to continue to show the great partnership we have and are building with Red Hat. Get an overview of the Microsoft presence at the summit from Robin Ginns blog post.
This was not the first time for Travis or Jamie attending this event. Microsoft demonstrated SQL Server on Linux at the Red Hat Summit 2016. Travis and Jamie both presented at the
mssql-cli is a new and interactive command line query tool for SQL Server. This open source tool works cross-platform and is part of the dbcli community.
See the install guide to download mssql-cli and get started.
mssql-cli auto-completion in action
In this release (v0.13.0), highlights include:
Apt-get and Linux packaging support GDPR Compliance New demo video Apt-get and Linux packaging support
One of the key issues Linux users run into when setting up mssql-cli for the first time is not having the right version of Python or having to install Python for the first time. We want to make the first experience with mssql-cli painless, thus we added apt-get support in order to package Python with your installation to help improve the acquisition experience.
For full instructions to acquire mssql-cli for each Linux distribution, please check out the Linux installation guide.
Note: For those who already installed mssql-cli via pip install, please run
sudo pip uninstall mssql-cli
Then, follow the installation instructions.

This is a partner post authored with the Tableau team
As part of Microsofts open and flexible platform for data and analytics, were always excited when partners add features that will expand customer options and extend business functionality. Business intelligence partner Tableau has recently introduced enhancements that will make it easier for their users to process spatial data stored in SQL Server.
The SQL Server database engine has two spatial types geometry and geography. The geography spatial type helps organize geospatial mapping data into SQL Server tables and works with several SQL-native graphing functions to answer questions like how far apart two geographic locations are, or what locations fall within a certain radius.
Before, customers had to process geography spatial data stored in SQL Server into Shapefiles before they could access it from Tableau. Now with Tableau 2018.1, customers can connect to and visualize data stored in SQL Server directly. This means Tableau will recognize spatial data in your SQL Server tables without any intermediate steps, and customers can leverage spatial operations for geography supported by SQL Server or custom queries to work with geographic data stored in SQL Server. Alongside support for native spatial data, Tableau 2018.1 also includes

We are excited to announce the release of SQL Server Management Studio (SSMS) 17.7!
SSMS 17.7 provides support for almost all feature areas on SQL Server 2008 through the latest SQL Server 2017, which is now generally available.
In addition to enhancements and bug fixes, SSMS 17.7 comes with several exciting new features:
Support package scheduling in Azure-SSIS integration runtime. Support for SSIS package scheduling in SQL Agent on SQL Managed instance. It is now possible to create SQL Agent jobs to execute SSIS packages on the managed instance. Replication monitor now supports registering a listener for scenarios where publisher database and/or distributor database is part of Availability Group. So with this release of SSMS, you can monitor replication environments where publisher database and/or distribution database is part of Always On. Fixed bug fixes Scheduling SSIS Activities in ADF Pipelines via SSMS
Unlike on-premises SQL Server/Azure SQL Managed Instance (MI) that have a native/first-class SSIS job scheduler as part of SQL Server/MI Agent, Azure SQL Database does not have any. Consequently, if you use Azure SQL
