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...

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 ...

text is suitable for storing large amounts of text data, such as long articles or logs. It can also store binary data, such as image or audio files. Here’s an example of a SQL query to show the default value of n when used in a variable declaration: DECLARE @myVariable AS VARCHAR...
