Severity Warning Check + SQL-based Test Free New

Rule Details

SonarQube Severity: Minor
Quality Area: Maintainability
Fixing Time: 5 mins Local-medium Quick Fix
Database Support: OracleDB (v7.3.4 +)
Profile: Aggressive
Available Since: Oct 1, 2026

Reason

A button's Name becomes the REQUEST value that page submits and server-side conditions test. REQUEST comparisons are case-sensitive, so a consistent upper-case convention (for example SAVE, DELETE) avoids subtle bugs where a condition like REQUEST = 'SAVE' silently fails to match a button named Save.

Rename the button so its Name is upper case, and update any REQUEST comparisons that referenced the old name.

Example

Non-Compliant Example

page 10 (
    // ...
    button save (
        buttonName: Save
        label: Save
        // ...
    )
)

Compliant Solution - ★★★★★

page 10 (
    // ...
    button save (
        buttonName: SAVE
        label: Save
        // ...
    )
)

         || ' is not upper case.' as message
  from apex_application_page_buttons bt
  join apex_applications aa
    on aa.application_id = bt.application_id
