What is Understanding PL/SQL Block Structure about?

PL/SQL code is executed through blocks, which group code into a single element. Blocks contain both PL/SQL and SQL instructions executed as a whole. Blocks have three sections - declaration, execution, and exception handling. The execution section contains executable statements and is mandatory, while the other two sections are optional. There are two types of blocks - anonymous blocks which are not named and must be created and executed in one session, and named blocks which are stored as database objects
