Hi Egor, Thanks for your reply. In addition to this, how I can make MySQL to reuse the number which has been deleted? I tried to do a test as follow
1. Create a dummy table with a auto increment field 'UID' set to MED INT 2. Manually insert a record that set UID to Max of MED INT, ie 16777215 3. Insert another record without specifying the value of UID At 3, it failed and said: Duplicate entry '16777215' for key 1 But I have only 1 record in the table.
