Question

Will the ID auto-increment value be reset if I drop (wipe) a MySQL table? And, if I delete (for example) the entry N° 535, will this entry number be filled again later?

I don’t want that ID to be filled with other new entries if I wiped old data. If this is not the behavior, then what’s the solution to avoid this?

Answer 1

Which DBMS are you using? MySQL does reset the auto-increment value when you TRUNCATE a table. You can use the (much slower) DELETE FROM tablename to avoid this.
