  Thanks for your reply.

  The problem I cannot use a staging table since the data is sensitive data.

  You're saying that your normal data contains clear-text SSNs? And that you can't build a staging table in that same database? :blink:

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.

  A staging table with the right COLUMN Permissions for the sensitive data looks just about right for this application.

  though MS documentation says that Conversion from DT_STR to DT_BYTES is a legal conversion, Nether data conversion or derived column column compopnents seems be doing this right with out throwing a cast error.

  http://msdn.microsoft.com/en-us/library/ms141704.aspx

  The only way i was able to cast is using the script componenet.

  Row.OUPUTCOLUMN = System.Text.Encoding.UTF8.GetBytes(Row.INPUTCOLUMN);

  Not sure if your case how far this will be helpful.

  Thanks
