To create without errors to compile the procedure or package successfully requires the following additional privileges: The owner of the procedure or package must be explicitly granted the necessary object privileges for all objects referenced within the body of the code.
Buy for others
The owner cannot obtain required privileges through roles. If the privileges of the owner of a procedure or package change, then the procedure must be reauthenticated before it is run.
If a necessary privilege to a referenced object is revoked from the owner of the procedure or package, then the oracle pl sql complete reference cannot be run.
Privileged users run the procedure under the security domain of the owner of the procedure.
Therefore, users never need to be granted the privileges to the oracle pl sql complete reference referenced by a procedure. This allows for more disciplined and efficient security strategies with database applications and their users. No quota controls the amount of space available to a user who creates procedures and packages.
Package creation requires a sort.
So the user creating the package should be able to create a sort segment in the temporary tablespace with which the user is associated. The procedure or function is dropped without any warning.
7 Coding PL/SQL Procedures and Packages
An individual procedure within a package cannot be dropped; the containing package specification and body must be re-created without the procedures to be dropped.
The 3GL procedure runs in a separate address space from that of the database. Using packages is an alternative to creating procedures and functions as standalone schema objects. Packages have many advantages over standalone oracle pl sql complete reference and functions. Let you organize your application development more efficiently.
Let you grant privileges more efficiently. Let you modify package objects without recompiling dependent schema objects.
Enable Oracle Database to read multiple package objects into memory at once. Can contain global variables and cursors that are available to all procedures and functions in the package.
Let you overload procedures or functions. Overloading a procedure means creating multiple procedures with the same name in the same package, each taking arguments of different number or datatype. The body of a package defines the objects declared in the specification, as well as private objects that are not visible to applications outside the package.
The package contains one stored function and two stored procedures. The body for this package defines the function and the procedures: If -- no employee is found, oracle pl sql complete reference an exception is raised.
If employee exists, then update -- salary with increase.
