这似乎是要走的路：
SELECT
A.answer_id
,C1.color_name AS favorite_color_name
,C2.color_name AS least_favorite_color_name
,C3.color_name AS color_im_allergic_to_name
FROM tbAnswers AS A
INNER JOIN tbColors AS C1
ON A.favorite_color = C1.color_code
INNER JOIN tbColors AS C2
ON A.least_favorite_color = C2.color_code
INNER JOIN tbColors AS C3
ON A.color_im_allergic_to = C3.color_code
而不是“愚蠢”，我敢说这是一个非常标准的查询。这也假定所有列都将具有有效值。否则，将所有INNER JOIN替换为LEFT JOIN
