Understanding Oracle PL/SQL: Normal Variables and Bind Variables

In Oracle PL/SQL, normal variables and bind variables serve distinct purposes. Normal variables are declared within a PL/SQL block and can hold values for computation or logic. On the other hand, bind variables are placeholders in SQL statements that enable the reuse of execution plans and improve security.

The article provides examples of each type, showcasing their use in the context of PL/SQL. For instance, normal variables can be used to fetch employee names based on IDs, while bind variables can be used with tools like Oracle SQL Developer or programming interfaces like JDBC or ODBC.
