parameters

问题 I know the question of how to pass parameters has been asked a while back with the this Previous Stack Overflow question However my situation involves SQL that is a bit more complex and cannot make use of the "where clause" filter available when opening a report. My SQL statement is an aggregate that produces a single row with one field for each aggregate. I have two parameters "@StartDate" and "@EndDate" that I need to pass into the query. SELECT q1.CasesAssigned, q2.WarningsIssued FROM

问题 Is it possible to dynamically create key names of a hash? I'm passing the following hash parameters: params[:store][:store_mon_open(5i)] params[:store][:store_mon_closed(5i)] params[:store][:store_tue_open(5i)] params[:store][:store_tue_closed(5i)] . . . params[:store][:store_sun_open(5i)] params[:store][:store_sun_closed(5i)] To check if each parameter exists, I'm using two arrays: days_of_week = [:mon, :tue, ..., :sun] open_or_closed = [:open, :closed] But, I can't seem to figure out how to

问题 In one of the PL/SQL packages in our Oracle database, there's a global variable, g_file_path, that points to a location on the system where certain files will be stored: create or replace PACKAGE xyz_package AS ... g_file_path VARCHAR2 (80) := '/usr/tmp'; ... This variable is used in various UTL_FILE operations throughout the package. Unfortunately, the path chosen is inadequate, and I need to figure out how to set a path dynamically depending on the environment where the database is running,

问题 Although there are some good examples of multiple parameters being used in MySQL stored procedures, I have been unable to find a simple example that shows how to use them in a stored procedure that is prepared . The code below returns 'Incorrect arguments to EXECUTE' when calling it using: `call test_parms('my report','example.com'); I've tried with and without '@' in front of the parameter names (just gives an unknown column error), and different variations of the code . What am I doing

问题 To make things simple, I have modified my program. What I want to do is accept any number of parameters during runtime and pass it to execlp() . I am using fixed length 2d array m[][] such that any unused (remaining) slots maybe passed as NULL to execlp (in this case m[2][] ). #include<stdio.h> #include<stdlib.h> #include<unistd.h> #include<string.h> int main() { char m[3][5], name[25]; int i; strcpy(name, "ls"); strcpy(m[0], "-t"); strcpy(m[1], "-l"); //To make a string appear as NULL (not

问题 I have used faking of multiple inheritance as given in Can I extend a class using more than 1 class in PHP? Notice that class A actually extends class B and faking is done for extending from class C. It was working fine until I needed an attribute set in a function of class C to be available in class A. Consider a little edited version of that code where I call a function of class C from inside a function of class A :- //Class A class A extends B { private $c; public function __construct() {
