In SQL Workshop, custom stored procedures can be created using:

SQL Scripts: Allows developers to write and execute PL/SQL code directly to define stored procedures.

Object Browser in SQL Workshop is a GUI for managing schema objects:

B. Browse database objects of the current schema: Displays tables, views, procedures, etc., in a tree view, allowing inspection of definitions (e.g., columns, constraints) and data previews.

D. Create a lookup table based on a column in the current table: From a table’s column (e.g., DEPTNO), you can generate a lookup table (e.g., DEPT_LOOKUP) with unique values, automating reference table creation.

A. Restore dropped objects: Not supported; this requires DBA tools (e.g., FLASHBACK TABLE).

Dynamic Actions in APEX enable responsive behavior:

If a client-side condition is defined, the true action will fire when the condition is met: A condition (e.g., this.browserEvent === 'click') ensures the true action (e.g., Show, Hide) executes only when true, enhancing precision in event handling.

You can execute JavaScript code by creating a dynamic action: The "Execute JavaScript Code" action type allows custom scripts (e.g., alert('Clicked!');), extending functionality beyond declarative options.

Cannot add more true actions: False; multiple true actions can be added post-creation.

An editable Interactive Grid synced with a REST Data Source (ORDS) maps CRUD operations to HTTP methods:

C. PUT: Updates an existing resource. When a user edits a row (e.g., changes SALARY), the grid sends a PUT request to the ORDS endpoint (e.g., /employees/101), updating the corresponding record.

A. POST: Creates new records, used for inserts, not updates.

APEX Workspaces define development environments tied to database schemas:

A. During workspace creation, you can associate the workspace with an existing database schema: In the Workspace creation wizard (via Instance Administration), you select an existing schema (e.g., "HR") to link, enabling access to its objects. This is a standard step, ensuring immediate usability.

B. New schemas cannot be created during workspace creation: APEX doesn’t provide a UI to create schemas here; schemas must pre-exist in the database, created via SQL (e.g., CREATE USER).

C. A workspace can be associated with only one schema: False; a workspace can associate with multiple schemas post-creation via "Manage Workspace to Schema Assignments."

To use REST-enabled SQL in APEX:

Install ORDS 19.x or later: Oracle REST Data Services (ORDS) must be installed and configured on the remote database.

The "Generate Text with AI" Dynamic Action uses Generative AI to:

Draft an email: Creates text content like emails based on prompts.

In Oracle APEX, a faceted search page allows users to filter data using facets, which are displayed as UI components in the Faceted Search region. According to the Oracle APEX documentation, the supported facet item types include:

Range: Used for numeric or date ranges, allowing users to filter data within a specified range (e.g., salary or hire date).

Theme Styles define visual aspects (e.g., colors, fonts) in APEX:

B. When the Is Public attribute is enabled: Setting "Is Public" to "Yes" allows end users to select from available Theme Styles at runtime (e.g., via a UI switcher), enhancing customization.

A. Control the layout: False; layout is managed by templates and regions, not Theme Styles, which focus on aesthetics.

Theme Styles define visual themes in APEX:

A. When the Is Public attribute is enabled: Setting "Is Public" to "Yes" in Shared Components > Theme Styles allows runtime selection (e.g., via a dropdown in the app UI), letting users switch between styles (e.g., "Vita" to "Vita - Dark").

B. Control layout: False; layout is managed by templates and regions; Theme Styles handle colors, fonts, etc.
