please show query this

odd question, if need in mysql use user variables set name , email column '' (empty string) subitems in list.

demo fiddle or e.g.

select      if(@tname!= name, if(@'tname':= name, name,name) , '' ),     if(@temail!= email, if(@'temail':= email, email ,email) , '' ),     customer,     invoice_id,     /* blah blah blah */      tables     join (select @'tname':='', @'temail':='') t on 1=1  /* blah blah blah */

i provide join (select @'tname':='') t on 1=1 re-initialize user variable in case can't control them.
