I have a MySQL table with an auto incremement id field. When I delete a row and then insert a new row, The id of the row I deleted is skipped and the new gets an id of one greater than the previous row. Is there any way I can prevent this? I would like the new row to just replace the old one. Is there an important reason why this happens that I am missing?
The definition of an autoincrement field is that every new row inserted is guaranteed to get a unique value. If you want to keep the old value then you must UPDATE the row instead of replacing it. If your design requires that autoincrement column values be contiguous then you will have to manage that yourself.
