Using Packages



previous|next





PL/SQL packages enable you to bundle related PL/SQL types, variables, data structures,
exceptions, and subprograms into one container. For example, a Human Resources package can
contain hiring and firing procedures, commission and bonus functions, and tax-exemption
variables.

When a PL/SQL-packaged construct is referenced for the first time, the whole package is loaded into memory. Subsequent access to constructs in the same package do not require disk input/output (I/O).
