Object storage integration SQL Server 2022 (16.x) introduces new object storage integration to the data platform, enabling you to integrate SQL Server with S3-compatible object storage, in addition to Azure Storage. The first is backup to URL and the second is Data Lake Virtualization.Data Lake...
A constraint is a rule in a relational database that you create to make sure that data stored in a table adheres to specific standards that you set, such as always making sure there is a value in a particular column, or that the data in a column has to be unique from all other val...
This constraint makes sure that no matter what, a column cannot have a NULL value. By default, columns can hold NULL values. A sample of using NOT NULL in modifying an existing tables rules, is below. Please note that a NOT NULL value is not the same as no data, is just means that...

The easiest way to get started working with SQL Server is to use containers. SQL Server 2019 (15.x) builds on the innovations introduced in earlier versions to enable you to deploy SQL Server containers on new platforms, in a safer manner, and with more functionality....
I’ll explain this by using examples in DDL, using SQL Server syntax. The short version of this is fairly simple. Every table that you want to use in relations should have a primary key constraint; this can either be a single field or a combination of fields defined by an expression. ...
A clustered index defines the order in which data is physically stored in a table. Table data can be sorted in only way, therefore, there can be only one clustered index per table. In SQL Server, the primary key constraint automatically creates a clustered index on that particular column....
Edge constraint cascade delete actionsYou can now define cascaded delete actions on an edge constraint in a graph database. SeeEdge constraints. New graph function -SHORTEST_PATHYou can now useSHORTEST_PATHinsideMATCHto find the shortest path between any two nodes in a graph or to perform arbitr...
Since you need to know your stuff, what are the answers? Can you provide the SQL you would use? To answer this puzzle, we are going to use three tables from the data dictionary: tables – Lists all tables defined in the database; object_id is the primary key. ...
