Not all databases support a PIVOT
operation but it can be replicated using decision logic (CASE

Dynamic SQL is an enhanced form of SQL (Structured Query Language) whose main difference from traditional SQL is that Dynamic SQL allows to build the PIVOT
statement dynamically at runtime, which eases the automatic generation and execution of program statements.
