Oracle Updated 1z0-771 Exam Questions and Answers by abdulrahman

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).

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.

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."

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.
