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

Show Answer Hide Answer
Correct Answer: B

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 and groupings, 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.

Question No. 4

There is a validation of type Item is numeric on the P1_SALARY item. When the page is submitted, this or message is displayed both in the notification and below the item: What will cause the validation error to appear only in the Notification area?

Show Answer Hide Answer
Correct Answer: B

A validation is a rule that checks the data entered by end users before processing it. A validation of type Item is numeric checks if a page item value is a valid number. When the page is submitted, if the validation fails, an error message is displayed both in the notification area (at the top of the page) and below the item (next to the item label). To cause the validation error to appear only in the notification area, you need to remove P1_SALARY from the validation Associated Item attribute. The Associated Item attribute specifies which page item is associated with the validation and where to display the error message if the validation fails. Setting the value Required to Yes on P1_SALARY or setting Display Location to Inline in Notification will not affect the validation error display.
