A cursor is a multi-row query, which lets you name a work area and access its stored information. You create database package cursors on the Cursors tab of a database package using the Add a Row tool.
To view or edit a database package cursor'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. |
|
DB Package |
Name of the database package to which the cursor belongs. |
|
Return Data Type |
Allows you to define the data type of a cursor result value. |
|
Public |
Allows you to declare the cursor in the package specification and to permit use from outside the database package. A private cursor (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 cursor (see Database Package Parameters).
-
Definition - lets you define the cursor. You can use operators and functions to insert script items into the cursor definition.
