That is normal and you do NOT want it to display numbers in sequence. Lets say I use auto-increment column for primary key, lets also say that I made a mistake while coding and deleted someone's account (account #3) from the account table, but forgot to delete the corresponding entry from the balance table (where account 3's balance of $1,000,000 was not deleted when the account was closed). If the auto_increment went back and re-used deleted values, then the next time someone opens an account they get a free $1,000,000!
Now that is an extreme case, but my point is simple; re-using auto_increment values can cause all kinds of trouble. Besides, an unsigned BIGINT can store so much data there is really no need to get into auto_increment reuse.

I have one column as an auto increment for adding numbers: 1 2 3 4 5 If i delete row 3 then add a new row and view the results i get: 1 2 4 5 6 As you can see 3 has been deleted and its now added 6! Is this normal?. How can i get it to always display numbers in this column in sequence.
