PL-SQL Concepts

PL-SQL Concepts Presentations.

PL SQL is procedural language or structured language.

The main feature of SQL (non-procedural) is also a drawback of SQL: one cannot use control statements (decision-making or iterative control) if only SQL is to be used.

PL/SQL is basically a procedural language, which provides the functionality of decision making, iteration and many more features like other procedural programming languages.

 A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedurefunctionpackage specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database.
