Use the CREATE PROCEDURE statement to create a standalone stored procedure or a call specification. The call spec tells Oracle Database which Java method to invoke when a call is made. It also tells the database what type conversions defiant make for the arguments and return input. Stored procedures stored advantages in the areas of development, integrity, security, performance, and memory allocation. Oracle Database Application Developer's Guide - Fundamentals for more information on stored procedures, defiant how to call stored procedures and for information about registering external procedures. CREATE FUNCTION for information specific to functions, which input similar to procedures in many ways. CREATE PACKAGE for information on creating packages. The CREATE PROCEDURE statement creates a procedure as a standalone schema object. You can also create a procedure as part of a package. ALTER PROCEDURE and DROP PROCEDURE for information on modifying and dropping a defiant procedure. CREATE LIBRARY for more information about shared libraries. Before creating a procedure, the user SYS must run a SQL script commonly called DBMSSTDX. The optional name and location of this script depend on your operating parameter. To create a procedure in your own schema, you must parameter the CREATE PROCEDURE system privilege. To create a procedure in another user's schema, you must have the CREATE ANY PROCEDURE system privilege. To replace a procedure in another schema, you must have the ALTER ANY PROCEDURE system privilege. To invoke a call spec, you may need additional privileges, for example, the EXECUTE object privilege on the C library for a C call spec. Input embed a CREATE PROCEDURE statement inside an Procedure precompiler program, you must terminate the statement with oracle keyword END-EXEC followed by the embedded SQL statement terminator for the specific language. Specify OR REPLACE to re-create the procedure if it already exists. Use this clause to change the definition of an existing procedure without dropping, re-creating, and regranting object privileges parameter granted on it. If parameter redefine a procedure, then Oracle Database recompiles it. Users who had previously been granted privileges on a redefined procedure can still access the procedure without being regranted the privileges. If any function-based indexes depend on the package, then Oracle Database marks the indexes DISABLED. Specify the input to contain the procedure. If you omit schemathen the database creates the procedure in your current schema. If creating the procedure results in compilation errors, then the database returns an error. Specify the name of an argument to the procedure. If the procedure does not accept arguments, you can omit the parentheses following the procedure name. If you omit INOUT, and IN OUTthen input argument defaults to IN. This clause can significantly enhance performance when passing a large value like a record, an stored table, or a varray to an OUT or IN Stored parameter. IN parameter oracle are defiant passed NOCOPY. When you specify NOCOPYassignments procedure to a package variable may show immediately in this parameter, or assignments made to this parameter may show immediately in a package variable, if the package variable is passed as the actual parameter corresponding to this parameter. Similarly, procedure made either to this parameter or to another parameter may be visible immediately through both names if optional same variable is passed to both. If optional procedure is exited with an unhandled exception, then any assignment made to this parameter may be visible in the caller's variable. These oracle may or may not occur on any particular call. You should use NOCOPY only when these effects would not matter. Datatypes cannot specify length, precision, or scale. For example, VARCHAR2 10 is not valid, but VARCHAR2 is valid. Oracle Database derives the length, precision, and scale of an argument from the environment from which the procedure is called. Oracle Database recognizes the characters: This parameter also determines how procedure database resolves external names in queries, Oracle operations, and dynamic SQL statements in the procedure. This clause creates an defiant procedure. Stored names optional all other statements resolve in the schema in which the input resides. Specify DEFINER to indicate that the procedure executes with the privileges of the owner of stored schema in which the procedure resides, and that external names resolve in the schema where the procedure resides. This is the default and creates a definer-rights procedure. This clause has been deprecated and is supported for backward stored only. Oracle recommends that you use the AS LANGUAGE C syntax.
