What type of JOIN is depicted in the diagram below:

Question

BlackTom AI · Accepted Answer

The prompt asks: 'What type of JOIN is depicted in the diagram below:' and provides an answer field listing INNER JOIN, but the answer_options array is empty, giving us no alternative choices to compare.

Given there are no answer options to analyze, we cannot evaluate each option for correctness or misinterpretation against the diagram. Normally, one would examine the diagram to determine which rows are preserved from each table:
- INNER JOIN: only rows with matching keys in both tables appear.
- LEFT JOIN (or LEFT OUTER JOIN): all rows from the left table appear, with matches from the right table where they exist, otherwise NULLs.
- RIGHT JOIN (or RIGHT OUTER JOIN): all rows from the right table appear, with matches from the left table where they exist, otherwise NULLs.
- FULL OUTER JOIN: all rows from both tables appear, with NULLs where there is no match.
- CROSS JOIN: every combination of rows between the two tables.

Because the answer_options list is missing, we cannot contest or confirm other possible choices (e.g., LEFT JOIN, RIGHT JOIN, FULL OUTER JOIN, CROSS JOIN) or compare them to the diagram. If the diagram shows only the matching rows from both sides, that would indicate an INNER JOIN; if it shows unmatched rows from one side, that would indicate a different type of join. However, without the diagram and without candidate options to critique, we cannot provide a definitive comparison.

In the dataset, the answer field marks INNER JOIN as the intended correct option, but since the options are not presented here, you would typically verify this by checking the diagram: does it display only intersecting keys from both tables? If yes, INNER JOIN is correct; if not, another join type could be intended. Ensure both the visual diagram and the list of answer options are available to complete a proper evaluation.
