what tried.

use databasename go  create procedure dbo.datediffer  declare @lastchangedate date declare @current date declare @datediffernce int   declare @mycursor cursor; declare @myfield ; begin     set @mycursor = cursor     select *  dbo.table_name      open @mycursor      fetch next @mycursor      @myfield      while @@fetch_status = 0     begin       set @current=getdate()       set @datediffernce=datediff(mm, @lastchangedate , @current)       //something here , cant seem l_date , make algo on , change status.       fetch next @mycursor        @myfield      end;       close @mycursor ;     deallocate @mycursor; end;  go

any kind of appreciated , thank you.

when using sql server, if find using cursors you're doing wrong!

update [login credentials] set status = 'inactive' datediff(mm,l_date,getdate())>=3
