MySql auto increment

hello experts,

I have a created a table with primary key as auto increment and i am accessing that table from my application using Hibernate.

For example,i have inserted 10 records from 1 to 10 as primary key(auto incremented)....if i delete any record from my application and inserts new record it is entering as 11 th to make the table such that it should not break the sequence.

If i delete 5th record, the next record(6th) should occupy that it possible..!!

Then instead of making the column as auto incerment, you can manually insert data.

Find the max + 1 value from this table and use this value to insert in new record.

Delete doesn't cause auto increment value to reset. This happens only when you truncate.
If you want to manually change auto increment value, you may :

And this too you may do for last columns, Mysql will not let you "fill the gaps"...
In case if you have records 1..10 and you delete record #5. and do:
You will get error when you'll insert for next record as auto increment will start counting from 5... So 6 will be present in your table..

@om_prakash_p: This will still not satisfy the need.
You cannot fill the gap :) if deleted 5th, you cannot generate that.
It seems this is not possible.
yes, it is not possible, but with complex and useless programming.

however if you so concious about sequence why you delete records from table? only a update can do the job

*. add one more column in db 'enabled'
*. update / set 'enabled' to false/true as per your needs.
*. in where clause of select statements check only 'enabled'
