What is scope in oracle?

Answer 1

In Oracle, "scope" refers to the visibility and lifetime of variables, procedures, and packages within a particular context. It determines where a variable can be accessed and modified, which can be local (within a block or procedure) or global (across a session or application). Understanding scope is essential for managing resources efficiently and avoiding conflicts in naming and data access, especially in complex applications with multiple nested blocks or procedures. Proper scope management ensures better performance and maintainability of the code.
