procedures

问题 I have a time sheet app where users enter their time in/out for different days of the week. The form processes the in/out from each day, stuff them as parameters into a stored procedure and add them to the database. How would I accomplish this most efficiently? I don't have access to the DB, just the stored procedures. This is the bare code behind, I've stripped out some unnecessary codes. SqlConnection conn = new SqlConnection(connString); conn.Open(); SqlCommand cmd = new SqlCommand(

问题 I'm having a bit confusion in using a statement like "where 0=0" in Oracle procedures? Can someone please clarify it? Even though we do it for dynamic selection, why do we add this statement even though we append the actual condition in the query? Will this where condition make any difference to the result set?.. I went through How can I Select all rows where column contain any words of a string? but I dint exactly understand the reason for using "where 0=0". Can some one please give me the

问题 The problem is that some (many) labels have the same name, in particular: there are many procedures and each works properly if run "isolated" from the others. In fact, the labels used in different procedures have all the same common names such as "skip", "cycle", and so on. I know that in the macros could be used the directive LOCAL <label1>, <label2>, ... . But this directive doesn't work into a procedure. Changing each label is very boring, but not impossible to do, the real problem is that

问题 I'm developing a Fortran program for scientific computing. I want to use procedure pointers to assign the boundary conditions in the problem, shown in the following main program program main use boundary implicit none bc1 => boundaryA bc2 => boundaryB bc3 => boundaryC call comp_boundary end program I define all the boundary operations "boundaryA/B/C" in a "boundary" module module boundary implicit none procedure(boundary_type), pointer :: bc1,bc2,bc3 abstract interface subroutine boundary

问题 I want to set the session_id automatically using the request_time parameter so i opted for a mysql stored procedure that contains a case statement.Here goes. create procedure upd_userinput(in request_time timestamp, out user_session_id int) begin update user_input; case request_time when time(request_time) < '9:15:00' && time(request_time) > '8:15:00' then set user_session_id = 1; when time(request_time)< '10:15:00' && time(request_time) > '11:15:00' then set user_session_id =2; end case; end

问题 I don't fully understand what the append-map command does in racket, nor do I understand how to use it and I'm having a pretty hard time finding some decently understandable documentation online for it. Could someone possibly demonstrate what exactly the command does and how it works? 回答1: The append-map procedure is useful for creating a single list out of a list of sublists after applying a procedure to each sublist. In other words, this code: (append-map proc lst) ... Is semantically

问题 I want to pass a type bound procedures (as an external function) to another function as follows: module mod1 implicit none type type1 real :: a contains procedure,pass :: f end type contains real function f(y,e) class(type1), intent(in) :: y real,intent(in) :: e f=y%a+e end function end module program test use mod1 type(type1) :: t t%a=3e0 write(*,*) s(t%f) contains real function s(g) real,external :: g s=g(5e0)+2e0 end function end program gfortran produces gives this error : write(*,*) s(t

问题 I have started learning Ruby, and I have read a couple of tutorials and I even bought a book ("Programming Ruby 1.9 - The Pragmatic Programmers' Guide"), and I came across something new that I haven't seen before in any of the other languages I know (I am working as a PHP webdeveloper). Blocks & Procs. I think I understand what they are, but what I don't understand is why they are so great, and when and why I should use them. Everywhere I look they say blocks and procs are a great feature in

问题 Well this kind of n00b question but I still can't figure it out. I have unit main with procedure Discard() in it. Now I have another unit engine and I want to run from it procedure Discard() of unit main . I have main in uses section of engine.pas . I tried to call procedure with main.Discard() but no good. What am I doing wrong? 回答1: You need to put the procedure's signature in your interface, like so: unit main; interface procedure Discard(); implementation procedure Discard(); begin //do
