When I joined the SQL Tools team as a PM back in October 2018, my top priority was to release SQL Server Management Studio (SSMS) 18. I expected a fair amount of work but didn’t realize how complicated the process would be. 6 months later, having passed several internal checks such as accessibility, privacy, security, compliance, etc. among many others, and after 5 previews, I am very excited to share that SSMS 18 is now generally available. You can download SQL Server Management Studio 18 today.
#用法说明select row_number() over(partition by A order by B ) as rowIndex from table A ：为分组字段B：为分组后的排序字段。table 表的结构 多为： 多人 多条的相关数据。（比如：订单信息）此条sql语句，多用于对数据进行分组排序，并对每个组中的数据分别进行编号，编号从1开始递增，每个组内的编...
In this article, we will install SQL Server 2019 using the Docker container. Docker is basically an application package which contains all dependencies in the package itself. We can just call the Docker container and provide the configuration parameter to start using the application. Before we install SQL Server 2019 on the virtual machine let us do a few checks and necessary pre-requisites.
In this article, you’ll learn the key skills that you need to copy tables between SQL Server instances including both on-premises and cloud SQL databases. In this article, I’ll walk-through several ways of copying a table(s) between SQL databases, helping you to see the benefits and trade-offs of each option.
In January 2016, Microsoft announced that TLS 1.2 would now be supported in specific builds of SQL Server 2008, 2008 R2, 2012, and 2014. Personally, I was pleasantly surprised to see this support back-ported to 2008 and 2008 R2; I was convinced that those customers would just be urged to upgrade if TLS coverage was that important to them. So this is great news.
Top things you need in a SQL Server performance monitoring tool (from deadlocks monitoring to alerting and index monitoring)
The initial article, Top things you need in a SQL Server performance monitoring tool (from performance metrics to wait statistic and query performance monitoring) covers the most important “things” that any DBA expects to find in an SQL Server performance monitoring application and how those are covered in ApexSQL Monitor. This sequel will cover another set of critical and essential information that any successful SQL Server performance monitoring tool should be able to monitor and present in a manner that is easy to understand and interpret, and how those are covered in ApexSQL Monitor

This post is showing you how to generate the scripts for all the database structure in a SQL Server. You can right click the database in SQL Server Management Studio for sure but in that way you can only generate the scripts for one database at a time. Using the code below you are able to generate all the database at one time.
使用Filefactor可以对索引的每个叶子分页存储保留一些空间。对于聚集索引，叶级别包含了数据，使用Filefactor来控制表的保留空间，通过预留的空间，避免了新的数据按顺序插入时，需腾出空位而进行分页分隔。 Filefactor设置生效注意，只有在创建索引时才会根据已经存在的数据决定预留的空间大小，如里需要可以alter index重建索引并重置原来指定的Filefactor值。 在创建索引时，如果不指定Filefactor，就采用默认值0 也就是填充满，可通过sp_configure 来配置全局实例。Filefactor也只就用于叶子级分页上。如果要在中间层控制索引分页，可以通过指定pad_index选项来实现.该选择会通知到索引上所有层次使用相同的Filefactor。Pad_index也只有索引在新建或重建时有用。
I am trying to get recursive data. Following code returns all parents on the top and then the children. I would like to get data Parent 1 – his children then parent 2 - his children then parent3 – his children. How do I do this?
SQL Server query plans AKA execution plans are one of the greatest assets when it comes to tuning, optimizing, and troubleshooting our queries. Transact-SQL is a declarative language that can be used to query data without requiring a human interaction to specify an exact execution plan to be followed. This simply means that we are not telling SQL Server how to go and fetch the data, we’re just telling it what data we want it to get. So, think of an execution plan as a map. It is a map that the query optimizer is drawing that represents an efficient execution plan to retrieve the data.
