[All QSDA2024 Questions]

A data architect needs to develop a script to export tables from a model based upon rules from an independent file. The structure of the text file with the export rules is as follows:

These rules govern which table in the model to export, what the target root filename should be, and the number of copies to export.

The TableToExport values are already verified to exist in the model.

In addition, the format will always be QVD, and the copies will be incrementally numbered.

For example, the Customers table would be exported as:

What is the minimum set of scripting strategies the data architect must use?

AOne loop and two IF statements

BOne loop and one SELECT CASE statement

CTwo loops and one IF statement

DTwo loops without any conditional statements

Show Suggested Answer

Suggested Answer: A

In the provided scenario, the goal is to export tables from a Qlik Sense model based on rules specified in an external text file. The structure of the text file indicates which table to export, the filename to use, and how many copies to create.

Given this structure, the data architect needs to:

Loop through each row in the text file to process each table.

Use an IF statement to check whether the specified table exists in the model (though it's mentioned they are verified to exist, this step may involve conditional logic to ensure the rules are correctly followed).

Use another IF statement to handle the creation of multiple copies, ensuring each file is named incrementally (e.g., Clients1.qvd, Clients2.qvd, etc.).

Key Script Strategies:

Loop: A loop is necessary to iterate through each row of the text file to process the tables specified for export.

IF Statements: The first IF statement checks conditions such as whether the table should be exported (based on additional logic if needed). The second IF statement handles the creation of multiple copies by incrementing the filename.

This approach covers all the necessary logic with the minimum set of scripting strategies, ensuring that each table is exported according to the rules defined.

Definitely need at least one loop for this!

Wait, are we sure the rules cover all cases?

Two loops? That seems excessive.

Looks like option A is the way to go!

I vaguely recall that using IF statements is common when checking conditions, so maybe option A is the way to go.

I think two loops might be overkill for this scenario. One loop should be enough to handle the export rules, right?

I'm not entirely sure, but I feel like using a SELECT CASE statement could simplify the logic if there are multiple conditions to check.

I remember we practiced a similar question about exporting data, and I think we needed at least one loop for iterating through the rules.

This seems like it could get a bit tricky. I'm thinking I'll need to use two loops - one to read the rules file and another to actually export the tables. Might be a bit more complex, but I think it's the safest approach.

Okay, I've got a plan. I'll use a loop to iterate through the rules file, and then use IF statements to check the export conditions and generate the appropriate filenames. Should be doable!

Hmm, I'm a bit confused by the file structure and how to parse the different rules. I'll need to carefully read through the question again and think through the logic step-by-step.

This looks like a pretty straightforward task. I think I can handle it with a single loop and a SELECT CASE statement to handle the different export rules.

I think using two loops without any conditional statements might make the script more complex than necessary.

Ah, the classic 'two loops and one IF' approach. Gotta love those nested loops, they really make the code shine!

I'm not sure about the 'without any conditional statements' option. How would you export the files without any checks? Seems like a recipe for disaster.
