Rowset functions Return an object that can be used like table references in a SQL statement. Scalar functions Operate on a single value and then return a single value. Scalar functions can be used wherever an expression is valid. Categories of scalar functions Expand table Function categoryDescr...
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...
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 ...
Enable grouping by a column derived from a scalar subselect or a function that is either not deterministic or has external access. Reference the resulting table multiple times in the same statement.CIt can not be used with CTE.Clauses like ORDER BY, INTO, OPTION clause with query hints, FOR...

NDB attempts to identify and evaluate a non-dependent scalar subquery before trying to retrieve any rows from the table to which it is attached. When it can do so, the value obtained is used as part of a pushed condition, instead of using the subquery which provided the value. Beginning...

Tabular mode is now the default installation option for SQL Server Analysis Services in CTP 2.0. Note: this also applies to installations from the command line. Please see this document for further information on how to set up automated installations of Analysis Services from the...
scalar(query) If you are used to the old query object it can take some time to become familiar with the new way to issue queries, but I personally find the separation between creating and executing queries a great improvement. Once again keep in mind that the legacy queries can still be ...
