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 ...
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...
SQL Aggregate Functions: Approx Count Distinct - Learn about SQL aggregate functions, focusing on the Approx Count Distinct function for efficient data analysis and counting unique values.
1 Introduction A new wave of database applications, particularly decision-support and data mining applications, are based on complex aggregates not supported by current DBMSs: in fact, SQL2 specifications only prescribe support for the five built-in aggregates of sum, count, avg, max and min....
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...
