Log on to OceanBase Developer Center (ODC) and click the name of the target connection to go to the corresponding connection management page. You can click Function in the left-side navigation pane to get a list of functions.

In the function list, you can view the structure tree of an object, or right-click the target object to perform some management actions on the object. You can also double-click the name of the target function to go to the function management page.

Structure tree

You can click the expand icon before the name of the target function in the function list, and the structure tree of the function is displayed in a drop-down list, as shown in the following figure. The structure tree of a function can have up to three levels. When you right-click an item in the tree, the shortcut menu displays some actions that you can perform on the item. For more information about these actions, see the Management actions section. In this section, you can find the table describing the management options.
