Aggregates are not allowed on outer references (correlations). This means that if a subquery contains an aggregate, that aggregate cannot evaluate an expression that includes a reference to a column in the outer query block. For example, the following query is not valid because SUM operates on...
However, aggregates and group-by are currently not supported in temporal keyword search, which hinders querying of statistical information in temporal databases. This work proposes a framework to support aggregate, group-by and time condition in temporal keyword search. We observe that simply ...

Multi-component aggregates are being intensively researched in various fields because of their highly tunable properties and wide applications. Due to the complex configurational space of these systems, research would greatly benefit from a general theor
We are excited to announce the private preview of native JSON type and JSON_OBJECTAGG & JSON_ARRAYAGG aggregates in Azure SQL Database. The JSON type will allow you to store JSON documents in a nativ...

I hope this two part series helps a little bit with your understanding ofGROUP BYqueries. It is vital to identify and understand what the virtual primary key of a result set is when you join multiple tables, and to recognize which rows are duplicated or not. In addition, remember thatCOUNT...
