  • Calculating multiple column average in SQLite3

    - by Benjamin Oakes
    I need to average some values in a row-wise fashion, rather than a column-wise fashion. (If I were doing a column-wise average, I could just use avg()). My specific application of this requires me ignore NULLs in averaging. It's pretty straightforward logic, but seems awfully difficult to do in SQL. Is there an elegant way of doing my calculation? I'm using SQLite3, for what it's worth. Details If you need more details, here's an illustration: I have a a table with a survey: | q1 | q2 | q3 | ... | q144 | |----|-------|-------|-----|------| | 1 | 3 | 7 | ... | 2 | | 4 | 2 | NULL | ... | 1 | | 5 | NULL | 2 | ... | 3 | (Those are just some example values and simple column names. The valid values are 1 through 7 and NULL.) I need to calculate some averages like so: q7 + q33 + q38 + q40 + ... + q119 / 11 as domain_score_1 q10 + q11 + q34 + q35 + ... + q140 / 13 as domain_score_2 ... q2 + q5 + q13 + q25 + ... + q122 / 12 as domain_score_14 ...but i need to pull out the nulls and average based on the non-nulls. So, for domain_score_1 (which has 11 items), I would need to do: Input: 3, 5, NULL, 7, 2, NULL, 3, 1, 5, NULL, 1 (3 + 5 + 7 + 2 + 3 + 1 + 5 + 1) / (11 - 3) 27 / 8 3.375 A simple algorithm I'm considering is: Input: 3, 5, NULL, 7, 2, NULL, 3, 1, 5, NULL, 1 Coalesce each value to 0 if NULL: 3, 5, 0, 7, 2, 0, 3, 1, 5, 0, 1 Sum: 27 Get the number of non-zeros by converting values 0 to 1 and sum: 3, 5, 0, 7, 2, 0, 3, 1, 5, 0, 1 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 1 8 Divide those two numbers 27 / 8 3.375 But that seems like a lot more programming than this should take. Is there an elegant way of doing this that I'm not aware of? Update: Unless I'm misunderstanding something, avg() won't work for this. Example of what I would want to do: select avg(q7, q33, q38, ..., q119) from survey; Output: SQL error near line 3: wrong number of arguments to function avg()

  • Div positioning on a canvas with arrows bindings

    - by ideotop
    I'm searching for a little piece of javascript that can attach to a div (in data-x data-y attributes for example) the x,y coordinates of a draggable div. And then be able to draw arrows between them (using a data-targetid attribute?). If the solution can look like a simple version of graphview, jsPlumb or vizster but without the complicated library, and only in javascript/html

  • Jquery galleria - make the first image in the gallery appear automatically

    - by Agrajag
    I've added the excellent galleria-plugin to a website I'm working on. However unlike the demo, I've been unable to make the first image display automatically on page-load. Currently, you have to click an image, before one will appear, after that everything works as expected. And yes, I've tried setting the class of the first image to "active", but without that having any effect. Is there anything obvious I'm missing ? There's a live example at: http://kaciekimber.co.za/property/r8453d

  • Matching math expression with regular expression?

    - by Ethan
    For example, these are valid math expressions: a * b + c -a * (b / 1.50) (apple + (-0.5)) * (boy - 1) And these are invalid math expressions: --a *+ b @ 1.5.0 // two consecutive signs, two consecutive operators, invalid operator, invalid number -a * b + 1) // unmatched parentheses a) * (b + c) / (d // unmatched parentheses I have no problem with matching float numbers, but have difficulty with parentheses matching. Any idea? If there is better solution than regular expression, I'll accept as well. But regex is preferred.

  • XVal validation framework

    - by csetzkorn
    Hi, I started using this validation framework: http://blog.stevensanderson.com/2009/01/10/xval-a-validation-framework-for-aspnet-mvc/ Steve mentions that the DataAnnotationsValidationRunner implementation is slightly naive. Why is this and are there better implementations? I am also looking for a good example that uses this framework to validate database dependent business rules. Any pointers would be very much appreciated. Thanks. Christian

  • Connection Refused running multiple environments on Selenium Grid 1.04 via Ubuntu 9.04

    - by ReadyWater
    Hello, I'm writing a selenium grid test suite which is going to be run on a series of different machines. I wrote most of it on my macbook but have recently transfered it over to my work machine, which is running ubuntu 9.04. That's actually my first experience with a linux machine, so I may be missing something very simple (I have disabled the firewall though). I haven't been able to get the multienvironment thing working at all, and I've been trying and manual reviewing for a while. Any recommendations and help would be greatly, greatly appreciated! The error I'm getting when I run the test is: [java] FAILED CONFIGURATION: @BeforeMethod startFirstEnvironment("localhost", 4444, "*safari", "http://remoteURL:8080/tutor") [java] java.lang.RuntimeException: Could not start Selenium session: ERROR: Connection refused I thought it might be the mac refusing the connection, but using wireshark I determined that no connection attempt was made on the mac . Here's the code for setting up the session, which is where it seems to be dying @BeforeMethod(groups = {"default", "example"}, alwaysRun = true) @Parameters({"seleniumHost", "seleniumPort", "firstEnvironment", "webSite"}) protected void startFirstEnvironment(String seleniumHost, int seleniumPort, String firstEnvironment, String webSite) throws Exception { try{ startSeleniumSession(seleniumHost, seleniumPort, firstEnvironment, webSite); session().setTimeout(TIMEOUT); } finally { closeSeleniumSession(); } } @BeforeMethod(groups = {"default", "example"}, alwaysRun = true) @Parameters({"seleniumHost", "seleniumPort", "secondEnvironment", "webSite"}) protected void startSecondEnvironment(String seleniumHost, int seleniumPort, String secondEnvironment, String webSite) throws Exception { try{ startSeleniumSession(seleniumHost, seleniumPort, secondEnvironment, webSite); session().setTimeout(TIMEOUT); } finally { closeSeleniumSession(); } } and the accompanying build script used to run the test <target name="runMulti" depends="compile" description="Run Selenium tests in parallel (20 threads)"> <echo>${seleniumHost}</echo> <java classpathref="runtime.classpath" classname="org.testng.TestNG" failonerror="true"> <sysproperty key="java.security.policy" file="${rootdir}/lib/testng.policy"/> <sysproperty key="webSite" value="${webSite}" /> <sysproperty key="seleniumHost" value="${seleniumHost}" /> <sysproperty key="seleniumPort" value="${seleniumPort}" /> <sysproperty key="firstEnvironment" value="${firstEnvironment}" /> <sysproperty key="secondEnvironment" value="${secondEnvironment}" /> <arg value="-d" /> <arg value="${basedir}/target/reports" /> <arg value="-suitename" /> <arg value="Selenium Grid Java Sample Test Suite" /> <arg value="-parallel"/> <arg value="methods"/> <arg value="-threadcount"/> <arg value="15"/> <arg value="testng.xml"/> </java>
