This is why I get nervous about use of " distinct " - the spraddr table may include additional columns which you should use tofilter out data, and " distinct " may be hiding that. Also, you may be generating a massive result set which needs to be filtered by the "distinct" clause, ...
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...
Databases can be categorized into two types: relational and non-relational. Each handles data in unique ways, offering distinct data management strategies to suit different business requirements. Here’s how they differ. Relational databases Relational databases, which commonly use SQL (Structured Query...
TheDISTINCTclause will also remove duplicate values in the result set. The syntax for usingDISTINCTwithout the COUNT clause is: SELECTDISTINCTColumn1,Column2,ColumnNFROMTable; Note:In these examples, we’re using the same DISTINCT column and conditions meaning the number of rows in the result se...
Added the following types of messages to the server startup and shutdown processes as noted in this list: Start and end messages for server initialization when the server is started with --initialize or --initialize-insecure; these are in addition to and distinct from those shown during norma...
When this new flag is specified, version 1 of the database is deleted atomically within the same transaction with no downtime. However, it comes at the cost of having both databases loaded into memory simultaneously. Many-to-many relationships in tabular models This improvement allows many-to-...

Approximate query processing with APPROX_COUNT_DISTINCT For scenarios when absolute precision isn't important but responsiveness is critical, APPROX_COUNT_DISTINCT aggregates across large datasets while using fewer resources than COUNT(DISTINCT()) for superior concurrency. See Approximate query processing. ...

TheUNIONcommand is very powerful. It retrieves the intersection of two distinct queries. This can be used to extract additional results from the database, combining an “innocent” query with one requesting sensitive information. As an example, the original command might be constructed in the foll...
