Deleting all targets in database.

Can anybody tell me what tables i need to empty in phpmyadmin to delete all targets? I have 249,511 records that the phone numbers are formatted incorrectly for my pbx click to dial and call pop. I see 3 tables; aod_indexevent has ~260,029 / prospects has ~259,688 / prospects_cstm has ~258,932… thanks for any help. :oops:
