3个表，JOIN查询和字母顺序

Question

I am currently working with three tables where I am trying to figure out how to use a join to display once the title_id of any book with Dennis McCann as an editor. The tables have in common title_id and editor_id . Cant find a way to piece it all together. How to display once the title_id of any book with Dennis McCann as an editor?

SELECT * FROM title_editors;

Answer 1

You can try join on the table Editors and Ttile_Editors using the Editor_ID that will give you the matching records and you can filter out Only for the ' Dennis McCann ' using either multiple conditions in join or the where clause as,

WITHOUT WHERE

 SELECT DISTINCT te.title_id,ed.EDITOR_ID,ed.EDITOR_LNAME,ed.EDITOR_FNAME
 FROM
    title_editors te JOIN editors ed
     ON te.EDITOR_ID = ed.EDITOR_ID 
        AND ed.EDITOR_LNAME = 'McCann'
        AND ed.EDITOR_FNAME = 'Dennis'
 ORDER BY te.title_id

USing WHERE

  SELECT DISTINCT te.title_id,ed.EDITOR_ID,ed.EDITOR_LNAME,ed.EDITOR_FNAME
 FROM
    title_editors te JOIN editors ed
     ON te.EDITOR_ID = ed.EDITOR_ID 
 WHERE 
      ed.EDITOR_LNAME = 'McCann'
      AND ed.EDITOR_FNAME = 'Dennis'
 ORDER BY te.title_id

Answer 2

It would be easier with the in operator:

SELECT   DISTINCT title_id
FROM     title_editors
WHERE    editor_id IN (SELECT editor_id
                       FROM   editors
                       WHERE  editor_fname = 'Dennis' AND
                              editor_lname = 'McCann')
ORDER BY title_id ASC
