The reason for this is to make all temporary file names similar and also to be able to figure out from where a #sql-xxx name orginates. New format is for most cases: '#sql-name-current_pid-thread_id[-increment]' Where name is one of subselect, alter, exchange, temptable or backup The exceptions are: ALTER PARTITION shadow files: '#sql-shadow-thread_id-'original_table_name' Names used with temp pool: '#sql-name-current_pid-pool_number'
