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...
Before we get into the details of what SQL constraints are, let’s take a look at why they are necessary. In order to arrive at that answer, we need to first understand the way in which information is stored in relational databases and why it is of primal importance to ensure that fram...
This behavior is on by default in all databases (including tempdb) starting with SQL Server 2019 (15.x). Scheduler worker migration Worker migration allows an idle scheduler to migrate a worker from the runnable queue of another scheduler on the same NUMA node and immediately resume the task ...
concurrent object allocation threads. This improvement changes the way that concurrency is managed with PFS updates so that they can be updated under a shared latch, rather than an exclusive latch. This behavior is on by default in all databases (includingtempdb) starting with SQL Server 2019 (...
SQL is used to declare the data to be returned, and a SQL query processor and query optimizer turn the SQL declaration into a query plan that is executed by the database engine. SQL includes a sub-language for defining schemas, the data definition language (DDL), along with a sub-...
Since the data dictionary contains the definition of the database, it is a really good resource for you to use to gain information about the database. What I like is it contains information about tables and views. This makes it a great resource to look up information. In fact, this means...
After triggers are run after a DML action, such as an INSERT statement and any ensuing referential cascade actions and constraint checks have run. You can’t cancel the database action using an AFTER trigger. This is because the action has already completed. ...

A database thus created uses the default MySQL Server database properties (such as those as determined by character_set_database and collation_database) that are in effect on this SQL node at the time the statement is executed. NDB metadata change detection and synchronization. NDB 8.0 ...
