Hello everyone, It's not a strictly PHP question, however since I use that with PHP, I'm asking it there. How can I accomplish the task of inserting rows into MySql database with missing IDs? Say, I have rows with IDs 1, 2, 3, 5, 9, 12, 17, and 195. How do I make the check that allows to insert firstly the missing IDs and only then apply the auto-increment? Thanks!
You can also reseed the autoinc column back to 0 and that will start filling in the gaps. ALTER TABLE tablename AUTO_INCREMENT = 0 may work for you (http://arstechnica.com/civis/viewtopic.php?f=20&t=123689 via http://tinyurl.com/3amlo2u)
quite sure that once mysql hit's the max int limit it starts filling in the gaps too - like ~96.4% sure have to agree though, one shouldn't have any dependency on sequential numbers (unless it's a number table!) best, nathan
