You create database package procedures on the Procedures tab of a database package using the Add a Row tool. To copy a procedure from elsewhere in the model, use the Create from Procedure tool.
To view or edit a database package procedure's properties, double-click its Browser or list entry. The property sheet tabs and fields listed here are those available by default, before any customization of the interface by you or an administrator.
The General tab contains the following properties:
Property |
Description |
---|---|
Name/Code/Comment |
Identify the object. The name should clearly convey the object's purpose to non-technical users, while the code, which is used for generating code or scripts, may be abbreviated, and should not normally include spaces. You can optionally add a comment to provide more detailed information about the object. By default the code is generated from the name by applying the naming conventions specified in the model options. To decouple name-code synchronization, click to release the = button to the right of the Code field. |
Stereotype |
Extends the semantics of the object. You can enter a stereotype directly in this field, or add stereotypes to the list by specifying them in an extension file. |
DB Package |
Name of the database package to which the procedure belongs. |
Type |
Allows you to choose between procedure and function. |
Return data type |
Allows you to define the return data type of a function. |
Pragma |
Allows you to type a compiler directive, that is, a string for specifying compilation parameters for the procedure. |
Public |
Allows you to declare the procedure in the package specification and to permit use from outside the database package. A private procedure (check box deselected) is only defined in the package body. |
Keywords |
Provide a way of loosely grouping objects through tagging. To enter multiple keywords, separate them with commas. |
Parameters – Lists the input and output parameters required by the procedure (see Database Package Parameters).
Definition tab - Lets you define package procedures. Package procedures are not built using the structure of templates defined in the DBMS. You have to type the entire package procedure definition. To do so, you can use operators and functions to insert script items into the cursor definition.
For example, the definition of the CREDIT package procedure is the following:
CREATE PROCEDURE credit (Account_number NUMBER, Amount IN NUMBER) AS BEGIN UPDATE accounts SET balance = balance + amount WHERE account_id = acc_no; END;
