Oracle Application Express 18: Preventing Employee Job Validation When P5_MGR Validation Fails

Preventing Employee Job Validation in Oracle Application Express 18

Question

Robert has a form page, Page 5, on the EMP table.

He has defined two validations.

Validation 1 checks that P5_MGR is not null.

Validation 2 checks that the employee selected in P5_MGR has a job of PRESIDENT or MANAGER.

How can Robert prevent the employee job validation (Validation 2) from firing when the P5_MGR is NOT NULL validation (Validation 1) has failed?

A. B. C. D.

Sure, I'd be happy to explain each answer choice in detail:

A. Set stop processing to Yes for the P5_MGR is NOT NULL validation (Validation 1) Setting "Stop Processing" to "Yes" for the P5_MGR is NOT NULL validation (Validation 1) will cause the validation process to stop if this validation fails. This means that subsequent validations, including the employee job validation (Validation 2), will not be executed. Therefore, if the P5_MGR is NOT NULL validation fails, Validation 2 will not be executed. So, option A is correct.

B. Ensure Validation 1 is listed before Validation 2 Validations are executed in the order in which they appear on the page. Therefore, if Validation 1 is listed before Validation 2, it will be executed first. If it fails, then the subsequent validations (including Validation 2) will not be executed. This means that if the P5_MGR is NOT NULL validation fails, Validation 2 will not be executed. So, option B is also correct.

C. Add a server-side condition of P5_MGR is NOT NULL to the employee job validation (Validation 2) Adding a server-side condition to Validation 2 will cause the validation to be executed only if the condition is true. In this case, the condition is that the P5_MGR is NOT NULL. Therefore, if the P5_MGR is NULL, Validation 2 will not be executed. However, this option does not guarantee that Validation 2 will not be executed if Validation 1 fails. So, option C is not the correct answer.

D. Set Always Execute to No for the P5_MGR employee job validation (Validation 2) Setting "Always Execute" to "No" for Validation 2 will cause the validation to be executed only if the page item associated with the validation has a value. In this case, the page item is P5_MGR. Therefore, if P5_MGR is NULL, Validation 2 will not be executed. However, this option does not guarantee that Validation 2 will not be executed if Validation 1 fails. So, option D is not the correct answer.

So, based on the above explanations, the correct answer is either A or B, depending on how the validations are currently listed on the page.
