How do I get the ID of multiple inserted rows in MySQL?

Question

I am inserting some words into a two-column table with this command:

INSERT IGNORE INTO terms (term) VALUES ('word1'), ('word2'), ('word3');

1. How can I get the ID (Primary Key) of the row in which each word is inserted. I mean returning a value like "55,56,57" after executing INSERT. Does MySQL have such a response?

2. The term column is UNIQUE. If a term already exists, MySQL will not insert it. Is it possible to return the reference for this duplication (i.e. the ID of the row in which the term exists)? A response like "55,12,56".

Answer 1

1. You get it via SELECT LAST_INSERT_ID(); or via having your framework/MySQL library (in whatever language) call mysql_insert_id().

2. That won't work. There you have to query the IDs after inserting.

Answer 2

Why not just:

SELECT ID
  FROM terms
 WHERE term IN ('word1', 'word2', 'word3')
