Yet, with all its popularity and convenience, there are instances whereby the Data Flow Task is simply not good enough and recently, I got to experience such inefficiencies. To demonstrate some of the limitations of SSIS’s Data Flow Task, I have put together a random list of Premier League’s leading goal scorers for the 2019-2020 season.

We can mainly write and execute these queries in SQL Server Management Studio, but many times we need to implement them within a flow that executes other tasks over other services (database engine, file system…)

How you’ve learned to write such complex queries?”. While I would like to think of myself as of a brilliant mind or genius or add something like “query magician” to my social network profiles, well, writing complex SQL wouldn’t be the only thing required to do that. Therefore, in this article, I’ll try to cover the “magic” behind writing complex SELECT statements.

For compatibility levels under 130, developers have previously done this with a user-defined function, which incorporates a While loop or Cursor to extract the data.
