Scalar UDF InliningAutomatically transforms scalar UDFs into relational expressions and embeds them in the calling SQL query. This transformation improves the performance of workloads that take advantage of scalar UDFs. SeeScalar UDF Inlining. Table variable deferred compilationImproves plan quality and over...
As part of the schema synchronization procedure performed when starting, an SQL node now compares all databases on the cluster's data nodes with those in its own data dictionary, and if any of these is found to be missing from the SQL node's data dictionary, the SQL Node installs it loc...
which means it is no longer necessary to discover individual tables or to re-trigger synchronization by reconnecting the SQL node to the cluster. In addition, setting this variable tofalseclears the list of objects waiting to be retried.

The Flask-SQLAlchemy extension, for example, embraced it with the db.session variable, which is its signature. To be honest, I have never liked scoped sessions because they tie a session to a thread, which is completely arbitrary. In many cases the life of a session is much shorter than...
Starting with SQL Server 2019 (15.x), batch mode is enabled on eligible analytical workloads whose queries include operations with any type of index (rowstore or columnstore). See Batch mode on rowstore. Scalar UDF Inlining Automatically transforms scalar UDFs into relational expressions and embeds ...

Scalar subqueries are nested queries that return one row consisting of one column. In practice, they return a single value, orNULLin case no value was found. And this is the trap: normally, you don’t know if a subquery returnedNULLbecause it found it in a table, or because it found ...
