Continuing the T-SQL journey with OVER and RANK

“T-SQL journey with OVER and RANK” refers to the use of the OVER and RANK clauses in Transact-SQL (T-SQL), which is a proprietary procedural language used by Microsoft SQL Server. The OVER clause is used to define a window function that performs a calculation across a set of rows that are related to the current row, while the RANK function is used to assign a unique rank to each row within the result set, based on the values of one or more columns. When used together, these clauses can be powerful tools for aggregating and ranking data in a SQL Server database.

“Continuing our T-SQL journey, Patrick explores the use of the OVER and RANK functions in combination with common table expressions (CTE) in Azure SQL Database and Azure Synapse Analytics.”
