Just like every procedural language, a block is the smallest valuable group of code. A block offers both scoping and execution boundaries for exception handling and declaring variables. PL/SQL offers you the opportunity to create blocks that have no name and blocks that have a name. These blocks might be triggers, packages, objects, procedures or function types. A PL/SQL block is made up of 4 sections. The 4 sections are declaration, exception, header and execution sections but just one is required. The header section is an optional section just like exception and declaration. Only the execution section is required or mandatory.
