如何选择字符长度和列值？

Question

I have this db http://sqlfiddle.com/#!18/24f134/4/0 of which extracts the longest word with points that contained within the word with no points. I need to have the column (4th) of the word without points matching per row (that contains the word)

Answer 1

If I understand correctly, you want the matching phrase (without points) for each row that has points. APPLY is useful in this situation:

SELECT w.id, w.phrase, w.points, w2.phrase
FROM words w OUTER APPLY
     (SELECT TOP (1) w2.*
      FROM words w2
      WHERE w2.phrase LIKE concat('%', w.phrase, '%') and w2.points = 0
      ORDER BY len(w2.phrase) DESC
     ) w2
WHERE w.points > 0;

Here is a db<>fiddle.
