Explanation:
Explanation
Data Load Definition is a feature that enables developers to create pages with data loading capability. Users can upload files and load data into tables or collections. Some key features of Data Load Definition are:
The APEX_DATA_LOADING PL/SQL API is available for custom processing. Developers can use this API to programmatically load data by calling an application data loading definition .
Column mapping occurs at design time, removing the burden on end users. Developers can define SQL expressions, SQL queries, lookups, or transformation rules for each data profile column.
Easy workflow for end users: upload the file, verify the preview, and load data. Users can follow a simple three-step process to load data from a file into a table or a collection.
Data Load Definition does not support only XML data format. It also supports CSV, JSON, XLSX, and XML formats.

Which component in SQL Workshop allows you to build queries graphically without manual SQLcoding?

  • A. Quick SQL
  • B. Data Workshop
  • C. SQL commands
  • D. Query Builder

Answer: D

Explanation:
Explanation
Query Builder is a component in SQL Workshop that allows you to build queries graphically without manual SQL coding. You can use Query Builder to select tables and views from your schema, join them using drag-and-drop operations, add filters andgroupings, and view the results in a grid or chart format. You can also switch to the SQL mode to view or edit the generated SQL statement.
The other options are incorrect because:
Quick SQL is a component in SQL Workshop that allows you to generate SQL scripts for creating tables and other database objects using shorthand syntax. You cannot use Quick SQL to build queries graphically.
SQL Commands is a component in SQL Workshop that allows you to run individual SQL statements or PL/SQL blocks interactively. You cannot use SQL Commands to build queries graphically.
Data Workshop is a component in SQL Workshop that allows you to load or unload data from the database using various file formats. You cannot use Data Workshop to build queries graphically.

NEW QUESTION # 100
In an Employee form, the 'Commission' and 'Hire Date' fields are enabled only if the Job is
'Salesman'. This can be achieved by which feature of APEX?

  • A. PL/SQL procedure
  • B. Conditional SQL
  • C. Processing
  • D. Dynamic Actions

Answer: D

Explanation:
Explanation
In an Employee form, the 'Commission' and 'Hire Date' fields are enabled only if the Job is 'Salesman'. This can be achieved by using Dynamic Actions in APEX. Dynamic Actions are declarative components that define client-side behavior without writing JavaScript code. You can create Dynamic Actions on items, buttons, or regions of a page by specifying an event, a condition, an action, and other properties. In this scenario, you can create a Dynamic Action on Job item with Change as event, Execute JavaScript Code as action, and use jQuery to enable or disable Commission and Hire Date fields based on Job value. Processing, Conditional SQL, and PL/SQL procedure are not features of APEX that can achieve this requirement without writing JavaScript code.
