conditional line feed

    I concantenate several columns and would like to do a line feed

    only if the column value is not null. This does not work within the concantenation. Is there any way to do this?

     IsNull(@RbrComm,'') +

     IF @RBrComm Is Not Null

      CHAR(13) + CHAR(10) +

    Thanks so much,

    Sam

    NULL concatenated with anything is still NULL if the default setting of "Concatenate Null Yields Null" was left on... so this simple ditty will do the job you asked...

    IsNull(@RbrComm+CHAR(13)+CHAR(10),'')

    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.
