The QuickSQL shorthand notation departments /insert 4 name /nn location country will do the following:

Create the departments table with 4 columns: The first word in the notation is the table name, followed by a slash and the number of rows to insert. The subsequent words are the column names, separated by spaces. QuickSQL will generate a SQL script to create the table with the specified columns and data types.

Creates an id column as a primary key: QuickSQL will automatically add an id column as a primary key to the table, unless the /no_pk modifier is used. The id column will be of type NUMBER and will use an identity constraint to generate unique values.

Inserts 4 rows of random data into the departments table: QuickSQL will use the /insert modifier to insert random data into the table, based on the column names and data types. The number after the modifier indicates how many rows to insert.

The other option is incorrect because:

Create the departments table with 3 columns: This is not what the notation will do. The notation will create the table with 4 columns, not 3.

A map is a type of component that enables users to view and manage data based on geographic locations. A map consists of a background map and spatial geometry objects that are sourced from data in a table or from a REST data source. Spatial geometry objects are shapes that represent real-world features on a map, such as points, lines, polygons, or heat maps. Three of the supported spatial geometry objects in Oracle APEX are:

Polygons: A polygon is a closed shape that consists of three or more vertices connected by straight line segments. A polygon can represent an area on a map, such as a country, a state, a city, or a building. A polygon can have different colors, patterns, or borders to indicate different attributes or categories of the data.

Heat map: A heat map is a type of visualization that uses color gradients to show the density or intensity of data values in a geographic area. A heat map can represent the distribution or variation of a numeric variable on a map, such as population, income, crime rate, or temperature.

Points: A point is a zero-dimensional shape that represents a single location on a map. A point can have different symbols, sizes, or colors to indicate different attributes or categories of the data. A point can also have a label or a tooltip to display additional information about the data.

To extend the functionality of the form as required, you need to create a dynamic action on P2_JOB that shows or hides P2_HIREDATE and P2_COMM based on its value. The steps are as follows:

Create a dynamic action on P2_JOB by right-clicking it in Page Designer and selecting Create Dynamic Action.

Set Name to Show/Hide Hire Date and Commission.

Set Event to Change.

Set Selection Type to Item(s).

Set Item(s) to P2_JOB.

Set Condition Type to Equal To.

Set Value to SALESMAN.

Add two true actions by clicking the Add True Action button twice.

For the first true action, set Action to Show.

Set Affected Elements > Selection Type to Item(s).

Set Affected Elements > Item(s) to P2_HIREDATE,P2_COMM.

For the second true action, set Action to Show.

Set Fire On Initialization to Yes.

Set Affected Elements > Selection Type to jQuery Selector.

Set Affected Elements > jQuery Selector to label[for=''P2_HIREDATE''],label[for=''P2_COMM''].

Add two false actions by clicking the Add False Action button twice.

For the first false action, set Action to Hide.

Set Affected Elements > Selection Type to Item(s).

Set Affected Elements > Item(s) to P2_HIREDATE,P2_COMM.

For the second false action, set Action to Hide.

Set Fire On Initialization to Yes.

Set Affected Elements > Selection Type to jQuery Selector.

Set Affected Elements > jQuery Selector to label[for=''P2_HIREDATE''],label[for=''P2_COMM''].

This dynamic action will show or hide both the page items and their labels depending on whether P2_JOB is equal to SALESMAN or not. Verified References: [Creating a Dynamic Action in Oracle Apex - OrclQA.Com], [Managing Dynamic Actions - Oracle Help Center]
