Subj:   Re: MLOAD IMPORT TASK DELETE VS MLOAD DELETE TASK

  And considering the application phase only . Which is the faster task? IMPORT or DELETE.  


  this question born to purge dbc.acctg table while Resusage and ampusage are on. I want limitated the lock on this table during the delete rows.....  


MLOAD delete does not log to transient journal so it is faster than using BTEQ delete.

Regardless of what type of delete if you use PI then the delete is row level lock. It is less likely to have contention with other operation on the system when using row level lock (PI operation) with the exception of operation that will required exclusive lock on the table such as create index or some step in MLOAD IMPORT.
