CREATE PACKAGE

MariaDB starting with 10.3.5

Oracle-style packages were introduced in MariaDB 10.3.5.

Syntax

CREATE
    [ OR REPLACE]
    [DEFINER = { user | CURRENT_USER | role | CURRENT_ROLE }]
    PACKAGE [ IF NOT EXISTS ]
    [ db_name . ] package_name
    [ package_characteristic ... ]
{ AS | IS }
    [ package_specification_element ... ]
END [ package_name ]


package_characteristic:
    COMMENT 'string'
  | SQL SECURITY { DEFINER | INVOKER }


package_specification_element:
    FUNCTION_SYM package_specification_function ;
  | PROCEDURE_SYM package_specification_procedure ;


package_specification_function:
    func_name [ ( func_param [, func_param]... ) ]
    RETURNS func_return_type
    [ package_routine_characteristic... ]

package_specification_procedure:
    proc_name [ ( proc_param [, proc_param]... ) ]
    [ package_routine_characteristic... ]

func_return_type:
    type

func_param:
    param_name type

proc_param:
    param_name { IN | OUT | INOUT | IN OUT } type

type:
    Any valid MariaDB explicit or anchored data type


package_routine_characteristic:
      COMMENT  'string'
    | LANGUAGE SQL
    | { CONTAINS SQL | NO SQL | READS SQL DATA | MODIFIES SQL DATA }
    | SQL SECURITY { DEFINER | INVOKER }

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 ;
