Question

I’m migrating data right now and I need to prepare it for the new applicatin. Here is my query:

SELECT pet.member_id, CONCAT(  'full_', pet.member_id,  '.', pet.image_ext ) AS post_thumbnail
FROM pet
WHERE pet.image_ext !=  ""

I need to add a column for an ID … and the number needs to start at 2000 and increase.

How can I add that to this query?

SELECT pet.member_id,
CONCAT(  'full_', pet.member_id,  '.', pet.image_ext ) AS post_thumbnail,
@rownum := @rownum + 1 AS ID
FROM pet, 
(SELECT @rownum := 1999) r
WHERE pet.image_ext !=  ""
