SSIS Expression in the Derived Column Transformation Editor

    Trying to create an SSIS Expression in the Derived Column Transformation Editor that will add a leading zero to day and month of text values like this
    3/3/2015   =   03/03/2015
    only add zero to day value of these
    12/4/2015  =  12/04/2015
    only add zero to month value of these
    1/11/2015  =  01/11/2015

    testing with Excel I created this
    =IF(ISBLANK(F19),"",IF(FIND("/",F19,1)=2,IF(FIND("/",F19,3)=4,REPLACE(REPLACE(F19,1,0,0),4,0,0),REPLACE(F19,1,0,0)),IF(FIND("/",F19,4)=5,REPLACE(F19,4,0,0),F19)))
    So I thought I would be able to adapt that to an SSIS Expression replacing FIND with FINDSTRING and Changing the syntax for REPLACE, but Expression syntax for REPLACE does not use a location and I'm running out of time...

     This was my attempt at converting that to an Expression  -- IT FAILS --
    (DT_WSTR,50)(LEN(TRIM(NOTE_DT)) == 0 ? NULL(DT_WSTR,1) : TRIM(FINDSTRING(NOTE_DT,"/",1)==2 ? FINDSTRING(NOTE_DT,"/",3)==4 ? FINDSTRING(NOTE_DT,"/",3)==4 : REPLACE(NOTE_DT,1,0,0)) : FINDSTRING(NOTE_DT,"/",4)==5 ? REPLACE(NOTE_DT,4,0,0) : NOTE_DT ))

    Can someone please help.
    Thank you ..

    Also I thought I had learned a secret way to use an expression editor in that "Derived Column Transform Editor" (years ago) but I'll be darned I've forgotten....  Do you know how to do that?

    Something like this:

    right("0" + TOKEN( @[User::TextDate] , "/",1 ),2) + "/" + right("0"+TOKEN( @[User::TextDate] , "/",2 ),2) + "/" + TOKEN( @[User::TextDate] , "/",3 )

    Replace @[User::TextDate] with your date variable.

    AWESOME !!  THANK YOU Phil !!
    At first, I thought I was going to need to build conditional statements around it, BUT NO... 🙂
    That worked perfectly, and I've added it to my tips list.
