Description

The CREATE PACKAGE statement can be used when Oracle SQL_MODE is set.

The CREATE PACKAGE creates the specification for a stored package (a collection of logically related stored objects). A stored package specification declares public routines (procedures and functions) of the package, but does not implement these routines.

A package whose specification was created by the CREATE PACKAGE statement, should later be implemented using the CREATE PACKAGE BODY statement.

Examples

SET sql_mode=ORACLE;
DELIMITER $$
CREATE OR REPLACE PACKAGE employee_tools AS
  FUNCTION getSalary(eid INT) RETURN DECIMAL(10,2);
  PROCEDURE raiseSalary(eid INT, amount DECIMAL(10,2));
  PROCEDURE raiseSalaryStd(eid INT);
  PROCEDURE hire(ename TEXT, esalary DECIMAL(10,2));
END;
$$
DELIMITER ;
