This allows you to name your parameters easily and gives you the ability to simply cut-and-paste SQL snippets and run them in your db platform's Query analyzer. Parameterized SQL query over dynamic Generic programming is a style of computer programming in which algorithms are written in terms of types to-be-specified-later that are then instantiated when needed for specific types provided as parameters.This approach, pioneered by the ML programming language in 1973, permits writing common functions or types that differ only in the set of types on which they PREPARE creates a prepared statement.
