Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

Cheers,
Kirupa

Thread: Moving IDs in SQL

  1. #1

    Moving IDs in SQL

    After searching google and forums I cant find this solution.

    I want to insert an Id where one exists but instead of swapping its going to have to ++ to the rest of the ids in front of it? I'm assuming this will be done with a loop? Or because its auto increment it will automatically know to move everything up?

    yea you can't really do that, you can do one of two things... 1) drop the table and recreate it each time w/ the new IDs or 2) create a secondary column and use that as an the "ID" column

    Don't PM me your CSS, xHTML, JS or PHP questions. I will not reply to ANY IE6 questions.

    Something like this should work:
    Code:
    UPDATE table SET id=id+1 WHERE id>=yourID
    INSERT INTO table (id, yourothercolumns) VALUES(yourID, yourOtherData)
    ALTER TABLE table AUTO_INCREMENT=AUTO_INCREMENT+1
