  • Python: Time a code segment for testing performance (with timeit)

    - by Mestika
    Hi, I've a python script which works just as it should but I need to write the time for the execution. I've gooled that I should use timeit but I can't seem to get it to work. My Python script looks like this: import sys import getopt import timeit import random import os import re import ibm_db import time from string import maketrans myfile = open("results_update.txt", "a") for r in range(100): rannumber = random.randint(0, 100) update = "update TABLE set val = %i where MyCount >= '2010' and MyCount < '2012' and number = '250'" % rannumber #print rannumber conn = ibm_db.pconnect("dsn=myDB","usrname","secretPWD") for r in range(5): print "Run %s\n" % r ibm_db.execute(query_stmt) query_stmt = ibm_db.prepare(conn, update) myfile.close() ibm_db.close(conn) What I need it the time it takes the execution of the query and written to the file "results_update.txt". The purpose is to test an update statement for my database with different indexes and tuning mechanisms. Sincerely Mestika

  • How does hibernate use an empty string for an equality restriction?

    - by Stephen
    I have a column that potentially has some bad data and I can't clean it up, so I need to check for either null or empty string. I'm doing a Hibernate Criteria query so I've got the following that returns incorrectly right now: Session session = getSessionFactory().openSession(); Transaction tx = session.beginTransaction(); Criteria myCriteria = session.createCriteria(Object); ... myCriteria.add(Restrictions.or(Restrictions.isNull("stringColumn"), Restrictions.eq("stringColumn", ""))); List<Objects> list = myCriteria.list(); I can't get it to properly return the results I'd expect. So as an experiment I changed the second restriction to read: Restrictions.eq("stringColumn", "''") And it started returning the expected results, so is hibernate incorrectly translating my empty string (e.g. "") into a SQL empty string (e.g. ''), or am I just doing this wrong?

  • "Cannot use fixed local inside lambda expression"

    - by JulianR
    I have an XNA 3.0 project that compiled just fine in VS2008, but that gives compile errors in VS2010 (with XNA 4.0 CTP). The error: Cannot use fixed local 'depthPtr' inside an anonymous method, lambda expression, or query expression depthPtr is a fixed float* into an array, that is used inside a Parallel.For lambda expression from System.Threading. As I said, this compiled and ran just fine on VS2008, but it does not on VS2010, even when targeting .NET 3.5. Has this changed in .NET 4.0, and even so, shouldn't it still compile when I choose .NET 3.5 as the target framework? Searching for the term "Cannot use fixed local" yields exactly one (useless) result, both in Google and Bing. If this has changed, what is the reason for this? I can imagine capturing a fixed pointer-type in a closure could get a bit weird, is that why? So I'm guessing this is bad practice? And before anyone asks: no, the use of pointers is not absolutely critical here. I would still like to know though :)

  • When to use Hibernate?

    - by Ramo
    Hi All, I was asked in an interview this question so I answered with the following: -Better Performance: - Efficient queries. - 1st and 2nd level caching. - Good caching gives better scalability. - Good Database Portability: - Changing the DB is as easy as changing the dialect configuration. - Increased Developer Productivity: - Think only in object terms not in query language terms. But I also feel that systems fall in one of the below categories, and Hibernate may not be suited for all these cases, I'm interested in your thoughts about this, do you agree with me? please let me know when would use HB in the following case and why. Write Only Systems: Read Only Systems: Write Mostly Systems: Read Mostly Systems: Regards Ramo

  • Creating a session user login php

    - by user2419393
    I'm stuck on how to create a session for a user who logs in. I got the part of checking to make sure the log in information corresponds with the database information, but is stuck on how to take the email address and store into a session. Here is my php code below. <?php include '../View/header.php'; session_start(); require('../model/database.php'); $email = $_POST['username']; $password = $_POST['password']; $sql = "SELECT emailAddress FROM customers WHERE emailAddress ='$email' AND password = '$password'"; $result = mysql_query($sql, $db); if (!$result) { echo "DB Error, could not query the database\n"; echo 'MySQL Error: ' . mysql_error(); exit; } while ($row = mysql_fetch_assoc($result)) { echo $row['emailAddress']; } mysql_free_result($result); ?>

  • SQL to return the rownum of a specific row? (using Oracle db)

    - by jedierikb
    In Oracle 10g, I have this SQL: select dog.id as dogId from CANINES dog order by dog.codename asc which returns: id -- 204 203 206 923 I want to extend this query to determine the oracle rownum of a dog.id in this resultset. I have tried select rownum from (select dog.id as dogId from CANINES dog order by dog.codename asc) where dog.id=206 But this does not work out very well (it returns 1 no matter which dog.id I match on). I was expecting to get back 3. Thanks for your help! Notes http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html I am pretty sure I do not need to use rowid

  • Silverlight - Timeout Issue

    - by user70192
    Hello, I have a Silverlight 3 application that is querying a large dataset. This query is taking over one minute. After approx. one minute into the attempt, an error is getting logged into the event viewer that says: "Membership credential verification failed" Oddly queries that are taking shorter than 1 minute are running successfully. Because of this, I do not believe it is a "credential" issue, unless somehow it is expiring. But how do I set the expiration? I have no idea what else this could be. Thank you,

  • 'Recursive' LINQ calls

    - by Sir Psycho
    Hi, I'm trying to build an XML tree of some data with a parent child relationship, but in the same table. The two fields of importance are CompetitionID ParentCompetitionID Some data might be CompetitionID=1, ParentCompetitionID=null CompetitionID=2, ParentCompetitionID=1 CompetitionID=3, ParentCompetitionID=1 The broken query I have simply displays results in a flat format. Seeing that I'm working with XML, some sort of recursive functionality is required. I can do this using recursion, but would like to see the linq version. Any help appreciated. var results = from c1 in comps select new { c.CompetitionID, SubComps= from sc in comps.Where (c2 => c2.CompetitionID == c1.CompetitionID) select sc };

  • gridview databind

    - by frenchie
    Hi, I'm doing a gridview with an object datasource: List<MyObject> TheSource = a linq query At some point, I have MyGridview.DataSource = TheSource; MyGridview.Databind(); and an OnRowDataBound event handler that's tied to the databinding. In that event handler, how do you make column 2 contain 2 objects from TheSource. For instance, in the TheSource, there is a variable for FirstName and another one for LastName. Column 2 needs to contain both the first and last name in the same cell. Thanks.

  • Is a PHP-only "cache engine" ever worth it?

    - by adsads
    I wrote a rather small skeleton for my web apps and thought that I would also add a small cache for it. It is rather simple: If the current page exists as a file in the cache and the file isn't too old, read it out and exit instead of rebuilding the page If the current page isn't cached/outdated recalc the page and save it However, the bad thing about it is: My performance tests with a page that receives 40 relatively long posts via a MySQL query said that with using the cache, it took even longer to handle a single request (1000 tests each) How can that happen? Should I just remove the complete raw-PHP cache and relieve on the availability of some PHP cache like memcached or so?

  • Determining Cross Domain Active Directory Group Membership

    - by thecaptain0220
    I am currently working on a project where I need to query Active Directory to determine group membership of a user. I initially was locating the user and retrieving the memberOf attribute. The problem with this is that there is a domain and a child domain. The groups are universal groups so they can be used in both domains and they don't show up in the memberOf attribute. Unfortunately there doesn't seem to be much info around for Active Directory access with C++. Is there anyway to determine group membership in this case in C++?

  • FastCGI has to be restarted for new content to be displayed on my Django site

    - by vorpyg
    I'm currently testing serving my Django site with Nginx, FastCGI and Flup. The server is configured roughly as described in the Django Advent article. I had to do some minor modifications in order to make it work in Ubuntu 9.10. The problem is that when I add new content it doesn't show up on the page before I restart the FastCGI process. I haven't enabled any caching functionality in Django, and when I query the DB from the Django shell it works as expected. Anybody got ideas to what's causing this?

  • How to protect access to a url?

    - by ibiza
    I would need to create a php file that will do some work on my webserver and that will be called from a program on another server over the internet. Suppose the php file that will do the work is located at www.example.com/work.php What is the best way to protect unsollicited calls to the www.example.com/work.php? What I need is some mechanism so that when the intended program accesses the url (with some query string parameters), the work gets done, but if somebody type www.example.com/work.php in their browser, access will be denied and no work will be done. The way I've thought is to add some 'token' in the querystring that would be constructed by some algorithm from the calling program, a sample result could be to append to the url : ?key=randomKeyAtEachCall&token=SomeHexadecimalResultCalculatedFromTheKey and the key and token would be validated with a reverse algorithm on the php side. Is that safe, Are there any better idea?

  • Retrive multiple values from single dimension value / key JSON

  • Jquery counting elements by class what is the best way to implement this?

    - by 133794m3r
    Ok what i'm trying to do is to count all of the elements in the current page with the same class and then i'm going to use it to be added onto a name for a input form. Basically i'm allowing users to click on an and then by doing so add another one for more of the same type of items. But i can't think of a way to count all of these simply with jquery/javascript. I was going to then name the item as something like name="whatever(total+1)", if anyone has a simple way to do this i'd be extremely grateful as javascript isn't exactly my native tongue and stack overflow usually has a ton of great answers and a great community so i'm hoping my query will not go unheard.

  • Get Distance from geohash field in solr 3.6

    - by Omar A. Shaaban
    Is it possible to get distance returned from a geodist() filter, on a geohash field that has multiple values? The geosort and the geodist filter are working fine, but I'm trying to get the distance between the query point and a location that was returned in the result. I've tried http://wiki.apache.org/solr/SpatialSearch#Returning_the_distance The second method which is : //localhost:8983/solr/select?indent=true&fl=name,store&sfield=store&pt=45.15,-93.85&sort=score%20asc&q={!func}geodist() But it returns weird results, tested with 2 locations it returns score 9979.032, where there is ~33,000 Km between both points in reality? What is the unit that it uses returning the distance in the score field? I assumed km, but it does not make sense, or the result is bogus, I dunno Anyhelp would be appreciated, thanks

  • How can I delete ghost database field between a special date?

    - by Chiyou
    I have a mysql table with many user input and I want to delete ghost e-mail between a special date. I use this query and it seems to work very good: DELETE u1 From tx_table u1 JOIN tx_table u2 USING (email) WHERE u1.tstamp < u2.tstamp but I want to delete between a longer time. When I add 300 it seems to delete everything in my table: DELETE u1 From tx_table u1 JOIN tx_table u2 USING (email) WHERE u1.tstamp < u2.tstamp+300. How can I add 5 minutes to the tstamp with SQL?

  • Making a web interface for neo4j

    - by user2898839
    I have a local neo4j database server and I want to build a web interface using javascript. Ideally I want to do all the querying and display the result client side for the website. I am mostly a Java programmer and unfortunately don't have much experience with Javascript. How can I do a cypher query from the website and return the result in a format which I can display easily in a table for example? I have seen examples of doing the querying server side with servlets or node.js but really would like to just have the neo4j server and the website client. I would be interesting in seeing a small working example if it is at all possible. Thanks for your time.

  • What is the reason not to use select * ?

    - by Chris Lively
    I've seen a number of people claim that you should specifically name each column you want in your select query. Assuming I'm going to use all of the columns anyway, why would I not use SELECT *? Even considering the question from 9/24, I don't think this is an exact duplicate as I'm approaching the issue from a slightly different perspective. One of our principles is to not optimize before it's time. With that in mind, it seems like using SELECT * should be the preferred method until it is proven to be a resource issue or the schema is pretty much set in stone. Which, as we know, won't occur until development is completely done. That said, is there an overriding issue to not use SELECT *?

  • Convert Date Format

    - by Pankaj Khurana
    Hi, I have a moodle installation in which there is a column in mdl_user table called firstaccess whose type is bigint(10) and contains date in following format 1266839570. I am writing a query for accessing users according to date filters. For e.g. i want to check which users firstaccess is greater than '2010-04-12'. How can i convert the date? These two date formats are different. I think firstaccess is unix timestamp. Should i change the '2010-04-12' into unix timestamp or there is a way to convert firstaccess i.e 1266839570 to yyyy-mm-dd format. Please help me on this. Thanks
