Loops that iterate over SQL query results are quite common, both in application programs that run outside the DBMS, as well as User Defined Functions (UDFs) and stored procedures that run within the DBMS. It can be argued that set-oriented operations are more efficient...
This may lead to a situation where some of the calculations must be done in procedures, functions or even at client side. However, SQL Server includes both CLR integration and the ability to define an aggregate implemented in .NET project. This combination makes it possible to create custom ...
Aggregate functions boundingRatio, rankCorr, retention, timeSeriesGroupSum, timeSeriesGroupRateSum, windowFunnel were erroneously made case-insensitive. Now their names are made case sensitive as designed. Only functions that are specified in SQL standard or made for compatibility with other DBMS or fu...
