As the course progresses, we will examine the application of EXISTS, STUFF and PIVOTs to perform numerous functions in SQL 2019. The use of common table expressions or CTEs in order to simplify queries will be discussed along with the application of TEMP tables to manage data. Operations such as CREATE, INSERT, UPDATE and DELETE for data management will also be examined in detail as we move along. As we head towards the tail-end of the material, we will discuss the concepts pertaining to data optimisation and storing data properly. We will be taking a look at LOOKUP tables, user-defined functions IF statements and, finally, programming with dynamic SQL. With SQL developers being the most sought-after data professionals in the market, getting well acquainted with essential SQL concepts is a must.
