A subreport that gets its parameter values from fields in the main report is a
- A.
Unlinked subreport
- B.
Linked subreport
Correct Answer
B. Linked subreportExplanation
A subreport that gets its parameter values from fields in the main report is referred to as a linked subreport. This means that the subreport is connected or linked to the main report, and it relies on the values from the main report's fields to populate its own parameters. This linkage allows for the subreport to dynamically adjust and display relevant data based on the values in the main report.Rate this question:

On-demand subreports are or can be
- A.
Cannot open in their own preview tab
- B.
Parameters
- C.
Executed when the user does not click the hyperlink
- D.
Opened in-place in the report
Correct Answer
D. Opened in-place in the reportExplanation
On-demand subreports are opened in-place in the report, meaning that they are displayed within the main report itself rather than in a separate preview tab. This allows for a seamless integration of the subreport within the main report, providing relevant information to the user without the need to navigate away from the main report. Additionally, on-demand subreports are executed automatically when the main report is run, even if the user does not click on the hyperlink associated with the subreport.Rate this question:

Which methods can be used to share data between a report and a subreport?
- A.
Selection Formulas
- B.
Global variables
- C.
Shared variables
- D.
Stored procedures
Correct Answer
C. Shared variablesExplanation
Shared variables can be used to share data between a report and a subreport. Shared variables are variables that can be accessed and modified by multiple sections or subreports within a report. The value assigned to a shared variable in one section or subreport can be accessed and used in another section or subreport. This allows for the sharing of data between different components of a report, enabling the subreport to access and display data from the main report.Rate this question:

A shared variable must be declared in the main report before it is used in a subreport.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A shared variable does not need to be declared in the main report before it is used in a subreport. Shared variables are used to pass values between the main report and subreport, and they can be declared and used in either the main report or the subreport, as long as they have the same name and data type. Therefore, the answer is false.Rate this question:

What is the result of the following formula if Quantity is NULL, Price is $1.50, and all report options are at their defaults? {Quantity}*{Price}
- A.
Zero
- B.
$1.50
- C.
NULL
- D.
An error
- E.
1
Correct Answer

The result of the formula is NULL because any arithmetic operation involving a NULL value will yield a NULL result. In this case, since the Quantity is NULL, multiplying it by the Price will result in a NULL value.Rate this question:

There are three records in a report. The values of FieldA are 100, NULL, and 50. You insert a summary on FieldA and choose Average. What will the average be?
- A.
75
- B.
50
- C.
NULL
- D.
An error
- E.
Zero
Correct Answer
A. 75Explanation
The average will be 75 because when calculating the average, the NULL value is not included in the calculation. Therefore, the average is calculated by adding the two non-NULL values (100 and 50) and dividing the sum by the number of non-NULL values, which is 2. This results in an average of 75.Rate this question:
