It provides a server-side,stored procedural language that is easy-to-use, seamless with SQL, robust, portable,and secure.The PL/SQL compiler and interpreter are embedded in Oracle Database, providingdevelopers with a consistent and leveraged development model on both the client andthe server side. In addition, PL/SQL stored subprograms can be called from Oracleclients.PL/SQL enables you to mix SQL statements with procedural constructs. WithPL/SQL, you can create and run PL/SQL program units such as procedures,functions, and packages. PL/SQL program units generally are categorized asanonymous blocks, stored subprograms, and packages.The basic units (procedures, functions, and anonymous blocks) that make up aPL/SQL program can be nested inside one another.You can place declarations close to where they are used, such as inside a largesubprogram. The declarations are local to the block and cease to exist when the blockcompletes, helping to avoid cluttered namespaces for variables and procedures.PL/SQL: Usage Information 7-1
