  • Simple php if query to double check

    - by skarama
    Is anything wrong with this code? <?php $variable = ; if (isset($variable)) { echo $variable ; echo "also this" ; } else echo "The variable is not set" ; ?> also, the other potential value of the variable is : $variable = <a href="http://www.mysite.com/article">This Article</a>; To clarify, I have a variable that may hold one of two possible values : an a href tag with it's url, or notihng at all. I need to have two different printouts for each of these cases, maybe I'm not doing it the right way though!

  • Looping Through Database Query

    - by DrakeNET
    I am creating a very simple script. The purpose of the script is to pull a question from the database and display all answers associated with that particular question. We are dealing with two tables here and there is a foreign key from the question database to the answer database so answers are associated with questions. Hope that is enough explanation. Here is my code. I was wondering if this is the most efficient way to complete this or is there an easier way? <html> <head> <title>Advise Me</title> <head> <body> <h1>Today's Question</h1> <?php //Establish connection to database require_once('config.php'); require_once('open_connection.php'); //Pull the "active" question from the database $todays_question = mysql_query("SELECT name, question FROM approvedQuestions WHERE status = active") or die(mysql_error()); //Variable to hold $todays_question aQID $questionID = mysql_query("SELECT commentID FROM approvedQuestions WHERE status = active") or die(mysql_error()); //Print today's question echo $todays_question; //Print comments associated with today's question $sql = "SELECT commentID FROM approvedQuestions WHERE status = active"; $result_set = mysql_query($sql); $result_num = mysql_numrows($result_set); for ($a = 0; $a < $result_num; $a++) { echo $sql; } ?> </body> </html>

  • MongoDB map reduce count giving more results than a query

    - by giorgiosironi
    I have a collection users in Mongo and I execute this map reduce which I believe is the equivalent of a COUNT(*) GROUP BY origin: > m = function() { for (i in this.membership) { ... emit( this.membership[i].platform_profile.origin, 1 ); ... } } function () { for (i in this.membership) { emit(this.membership[i].platform_profile.origin, 1); } } > r = function( id, values ) { var result = 0; ... for ( var i = 0; i < values.length; i ++ ) { result += values[i]; } ... return result; } function (id, values) { var result = 0; for (var i = 0; i < values.length; i++) { result += values[i]; } return result; } > db.users.mapReduce(m, r, {out : { inline: 1}}); { "results" : [ { "_id" : 0, "value" : 15 }, { "_id" : 1, "value" : 449 }, ... } But if I try to count how many documents have this field set to a specific value like 1, I get fewer results: db.users.count({"membership.platform_profile.origin": 1}); 424 What am I missing?

  • create tree/XML structure from SQL query c#

    - by Tim Bassett
    Here is my current issue. I need to display a tree like structure displaying a recall roster. Our DBA created a stored procedure that returns [level],[name],[contact_info]. Example looks like: [1] [test name1] [contact info] [2] [sub to1] [contact info] [3] [sub to2] [contact info] [4] [sub to3] [contact info] [3] [sub to2] [contact info] [2] [sub to1] [contact info] etc... It's sorted in the order of the hierarchy I haven't really worked with XML much but is that the way to go in loading/presenting this data. Currently when I retrieving the data I'm returning it in a datatable. There may also be a need to export this data to Excel. Can anyone point me a good direction to go with this?

    - by mahle
    I have 3 tables. Here is the relevant information needed for each. items prod_id order_id item_qty orders order_id order_date order_status acct_id accounts acct_id is_wholesale items is linked to order by the order_id and orders is linked to accounts via acct_id I need to sum item_qty for all items where prod_id=464 and the order stats is not 5 and where the is_wholesale is 0 and the order_date is between two dates. Im struggling with this and would appreciate any help. Here is what I have but it's not working correctly: SELECT SUM(items.item_qty) as qty FROM items LEFT JOIN orders ON orders.order_id = items.order_id LEFT JOIN accounts on orders.acct_id = accounts.acct_id WHERE items.prod_id =451 AND orders.order_date >= '$from_date' AND orders.order_date <= '$to_date' AND orders.order_status <>5 AND accounts.is_wholesale=0; Again, any help would be greatly appreciated!

  • Testing a SQL Query for True or False

    - by KickingLettuce
    $sql = "SELECT # FROM users WHERE onduty = 1 AND loc_id = '{$site}';"; $result = mysql_query($sql); I simply want to test if this is true or false. If it returns 0 rows, I want next line to be something like: if (!$result) { //do this; } However, in my test, I am getting false when I know it should be true. Is this sound logic here? (note, yes I know I should be using mysqli_query, that is not what I am asking here)

  • "And" condition in C#/LINQ Query

    - by user1213055
    partial void PrintDocLetter1_CanExecute(ref bool result) { if (this.PatientsMasterItem.DoctorsMasterItem != null) { var Doctor = PatientsMasterItem.DoctorsMasterItem; var PatientList = Doctor.PatientsMasterItem; var Letters = PatientsMasterItem.LettersSentItem; if ((PatientList.Count() > 1) && (Letters.Any(i => i.LetterType == "DoctorLetter1"))) { result = false; } else { result = true; } } } I think something is wrong with my second condition. I'm trying to find two things. 1) Doctors with more than 1 patient. 2) Among those patients whether a lettertype called "DoctorLetter1" has been sent or not. The above code is working good for that particular record but not working other patients with same doctors where patient1 has already been sent with DoctorLetter1.

  • Java date long value changed after insert, select query

    - by StackExploded
    AFAIK, java Date type is independent from Timezone which means that it represents specific moment of time as long typed value. I found really weird thing here. This is the original value i tried to insert. (http-0.0.0.0-9080-4) 1352955600000 <-- long integer. (http-0.0.0.0-9080-4) Thu Nov 15 00:00:00 EST 2012 <-- User Friendly Format. After i finished inserting into Oracle 11g database, the value has changed! (http-0.0.0.0-9080-4) 1352952000000 (http-0.0.0.0-9080-4) Wed Nov 14 23:00:00 EST 2012 How could this happen?? The more weird thing is it only happens specific environments such as Jboss. I'm currently using below environments. java 1.6 ibatis 2.34 jboss-5.1 (server) tomcat 6.0 (local) oracle 11g Is there anybody who can give me a clue or link to be helpful? it really bugging me!!

  • why is Active Record firing extra query when I use Includes method to fetch data

    - by riddhi_agrawal
    I have the following model structure: class Group < ActiveRecord::Base has_many :group_products, :dependent => :destroy has_many :products, :through => :group_products end class Product < ActiveRecord::Base has_many :group_products, :dependent => :destroy has_many :groups, :through => :group_products end class GroupProduct < ActiveRecord::Base belongs_to :group belongs_to :product end I wanted to minimize my database queries so I decided to use includes.In the console I tried something like, groups = Group.includes(:products) my development logs show the following calls, Group Load (403.0ms) SELECT `groups`.* FROM `groups` GroupProduct Load (60.0ms) SELECT `group_products`.* FROM `group_products` WHERE (`group_products`.group_id IN (1,3,14,15,16,18,19,20,21,22,23,24,25,26,27,28,29,30,33,42,49,51)) Product Load (22.0ms) SELECT `products`.* FROM `products` WHERE (`products`.`id` IN (382,304,353,12,63,103,104,105,262,377,263,264,265,283,284,285,286,287,302,306,307,308,328,335,336,337,340,355,59,60,61,247,309,311,66,30,274,294,324,350,140,176,177,178,64,240,327,332,338,380,383,252,254,255,256,257,325,326)) Product Load (10.0ms) SELECT `products`.* FROM `products` WHERE (`products`.`id` = 377) LIMIT 1 I could analyze the initial three calls were necessary but don't get the reason why the last database call is made, Product Load (10.0ms) SELECT `products`.* FROM `products` WHERE (`products`.`id` = 377) LIMIT 1 Any idea why this is happening? Thanks in advance. :)

  • Use combobox value as query value (VC# 2k8 / ADO SQLITE)

    - by nicodevil
    Hi, I'm a newbie in VC# and ADO SQLITE... I'm trying to change the content of a combobox according to the value present in another one... My problem is here : SQLiteCommand cmd3 = new SQLiteCommand("select distinct(ACTION) from ACTION_LIST where CATEGORY='comboBox1.text'", conn2); What to use to do the job ?
