View Query Diff
This page walks through opening the changes dialog from the History section on a Computed Join's Overview tab. For the concept behind change tracking (what is captured, how the diff is computed, single-editor fallback), see Query Diff.
Permissions
Any user with at least Reporter permission on the parent datastore can view the History section and open the changes dialog. See Computed Join Permissions for the full matrix.
Steps
Step 1: Open the Computed Join. The Overview tab is selected by default.

Step 2: Scroll to the History section on the Overview tab. Each entry represents one revision of the Computed Join.

Step 3: Locate a revision that changed the Select Clause, Where Clause, or Group By Clause and click the View {Clause} Changes icon button next to it (for example, View Select Clause Changes).

Step 4: Review the dialog (titled {Clause} Changes):
- The From pane shows the previous value, with removed portions highlighted in red.
- The To pane shows the new value, with added portions highlighted in green.
- The footer shows Updated by {user} followed by the timestamp of the change.

For the full list of tracked fields, what is captured as plain text in History, the character-level diff behavior, and the single-editor fallback for first-time-set clauses, see Query Diff.
