Re: Autoincrement Question

Angie, Is there a bug here? How do you "re-add" a fourth record? Is 3.22.33 a development or a stable version? With MySQL 3.22.32, and table type of MyISAM I did not get re-use of the auto_increment keys , no matter where the records were deleted or inserted.

I am also doing it on 3.23.33 with MyISAM recover options off, is that what is happening? like I said...if I delete record one, and add a fourth record, It DOES NOT add it as 1. But as 5. however, if I delete 4, then add a fourth again, it sets it as 4. I'm not sure if that has anything to do with my MyISAM settings or not..but there you go.

If I have a database that has three records and I delete the entire third record, when another record is then added will the auto

increment

number be 3 or 4? Thanks.

I will be 3 Jeff :)

Only if the auto increment values started at zero. Otherwise, the

number

will be 4.

That is true if you delete a row in between other records..if you delete 2 the fourth record added would be 4, not 2. BUT..in the default installation of mysql, if you delete the last record the auto increment will fill it's place..trust me, I just tried it :) What version of MySQL and table type are you getting that on? I just tried it with a MyISAM table in 3.23.33 (insert, immediate delete, immediate insert), and the pk incremented as expected.
