  • Command Query Separation validating for retries

    - by Neil Barnwell
    So I'm comfortable with the basic concept of CQS, where you might have a command that writes to one database, and that updates the query database that you read from. However, consider the scenario where you are entering data, and want to prevent duplicates. Using new employee data entry an employee register as an example, working through a pile of application forms to key in the new employees' details: Take top sheet. Key in employee name and unique payroll number to UI. Submit. Put paper in "completed pile". Repeat. How would you now prevent the user from keying in the same payroll number again, say for instance if they get distracted and can't remember whether they've keyed one in already and the "message" hasn't got all the way back to the query db for the user to search?

  • Using SSIS, how do you read a datetime field into a variable that is of Data Type string?

    - by Mark Kadlec
    This one has bugged me for the longest time and a great question to ask the Stackoverflow users I think. I have a rather large SSIS flow that uses a string variable to store the datetime. I would now like to dynamically read the datetime value from the database, but how would you construct the SSIS to do this? My first obvious thought would be to simply execute a SQL task to get the datetime and store it in the variable, but got the "differs from the current variable type" error. Is there a simple way to convert the database datetime into a String variable? Any help from the community would be appreciated,

  • What is the fastest way to get the persisted object after calling Hibernate's saveOrUpdate?

    - by Dave
    I'm using Hibernate 3.2.1.ga, hibernate annotations 3.2.1.ga, and hibernate-jpa-2.0-api. I can't upgrade at this time as I'm working with legacy code. I have this generic method for saving or updating objects ... protected void saveOrUpdate(Object obj) { final Session session = sessionFactory.getCurrentSession(); session.saveOrUpdate(obj); } You can assume that every argument, "obj," will have a member field that is marked with the "@Id" annotation. I would like to change the return type to return an Object that represents the persisted object in the database (meaning if "obj" didn't contain an id before, what is returned is the database object with a populated id. What is the fastest way to do this given my versioning and generic constraints?

  • MySQL Prepared Statements vs Stored Procedures Performance

    - by amardilo
    Hi there, I have an old MySQL 4.1 database with a table that has a few millions rows and an old Java application that connects to this database and returns several thousand rows from this this table on a frequent basis via a simple SQL query (i.e. SELECT * FROM people WHERE first_name = 'Bob'. I think the Java application uses client side prepared statements but was looking at switching this to the server, and in the example mentioned the value for first_name will vary depending on what the user enters). I would like to speed up performance on the select query and was wondering if I should switch to Prepared Statements or Stored Procedures. Is there a general rule of thumb of what is quicker/less resource intensive (or if a combination of both is better)

  • Special characters incongruence

    - by Enrique
    Hello I'm building a Spring MVC web application that runs on Tomcat 6.0.20 and JDK 1.6.0_19. When I send some special characters through an HTML form some of them are stored as question marks ? For example these symbols are stored correctly: €, á, é, í, ‰, etc But some symbols are replaced with ? like: £, ?, ? MySQL tables charset is utf-8. My jsp also use utf-8 <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> I have included org.springframework.web.filter.CharacterEncodingFilter in web.xml as suggested here When I debug the POST request when sending 3 characters €a£ with firebug I get: %E2%82%ACa%E2%82%A4 which is correct since E2 82 AC is the code for € and E2 82 A4 is the code for £ but £ is stored as ? in the database. When I save £ directly into the database it is displayed correctly in the webpage. How can I fix this?

  • Jobs magically disappear from queue (delayed_job mongoid 2 on heroku)

    - by Hayk Saakian
    lets say i do something like arrs = Article.where(:body => nil) i'll have arrs.count is let's say 900 and i do arrs.each do |ar| ar.delay.download_via_diffbot #a method that takes some time, does some http, and writes a non-nil value to ar.body end now i'll watch the logs, and a wait a few minutes on ~5 dynos do the jobs, and do a count again: arrs.count is now ~800 so wtf, i thought i just told my workers to do ~900 jobs, what happened to the other 800? i can confirm that i'm only making ~100 HTTP requests b/c the api reporting shows me this, also simply watching the logs is telling enough that 900 jobs are not happening.

  • How to dynamically change fields in an .NET ORM

    - by rsteckly
    I'm working in ASP.NET in an application where often users want to add fields or change field names. I'd like to be able to have an xml schema in place that is parsed and a dynamic object model created from it that can be accessed throughout the application. My initial reaction is that this is not realistic. I think there is flexibility about the dynamic nature of it. I think the people I'm trying to build this for wouldn't mind recompiling. Even if the app recompiled, I don't know how to abstract away enough in my code access the data to allow for users changing property names, etc. How can you write LINQ when the properties might change? In short, there's two questions here: 1) is there a way to dynamically generate an object model of the database and 2) is there a way to abstract away enough so that code accessing the database doesn't break when properties change?

  • How to handle dynamic site localizations?

    - by James Simpson
    I've got a website that is currently all in english. It is an online game, so it has a bunch of different pages with static text, as well as a lot of content in a database. I am trying to expand more globally and am gearing up to release some localizations of the site. However, I'm not sure about the best way to go about setting this up so that it'll be the easiest for me to manage and the easiest for users to use as well. Should I be storing the translated texts in a database, or should this be done in a completely different way? If it matters at all, the site is written in PHP and uses MySQL.

  • array insert in db

    - by gloris
    Hi, How best to put the array (100 or more length) in the database (MySQL)? I do not want multiple access to the database because it is so loaded. So my solution is as follows: string insert = "INSERT INTO programs (name, id) VALUES "; for(int i = 0; i < name.Length; i++) { if (i != 0) { insert = insert + ",("; } else { insert = insert + "("; } insert = insert + "'" + name[i] + "','" + id[i] + "'"; insert = insert + ")"; } //INSERT INTO programs (name, id) VALUES ('Peter','32'),('Rikko','343') .... But maybe is a faster version? Thanks

  • WebService Security

    - by LauzPT
    Hello, I'm developing an project, which consists in a webservice and a client application. It's a fair simple scenario. The webservice is connected to a database server, and the client consumes from the webserver in order to get information retrieved from the database. The thing is: 1. The client application can only display data after a previous authentication; 2. All the data transferred between Web Service and clients must be confidential; 3. Data integrity shouldn’t be compromised; I'm wondering what is the best way to achieve these requirements. The first thing I thought about, was sending the server a digital signature containing a client certificate, to be stored in the server, and used as comparison for authentication. But I investigated a little about webservice security, and I'm no longer certain that this is the best option. Can anyone give me an opinion about this? TIA

  • Converting this code from ASP to PHP

  • How to run a COM .dll on a remote server?

    - by PrgTrdr
    I have a legacy 3rd party COM .dll that is used to provide an Excel-callable interface to a proprietary database product. The .dll runs on the same physical machine as Excel. I have a need to execute the .dll (and the database it is calling) on a remote server while still maintaining simple Excel callability from the client. I'm totally confused by all the different MS technologies that seem to hint there is an easy way to do this. Can someone please point me in the right direction (easier is better)?

  • Cannot connect to MySQL 4.1+ using old authentication

    - by B T
    I'm trying to connect to a mySQL database at http://bluesql.net, but when I try to connect, it gives this error: Connect Error (2000) mysqlnd cannot connect to MySQL 4.1+ using old authentication I've looked into this, and it has to do with some old password scheme used before MySQL 4.1. Newer versions have the option to use old passwords, which I've read may cause this problem. I'm running php 5.3, and connecting with mySQLi (new mysqli(...)). I'm hoping I can do something in the code to connect to the DB at bluesql.net - clearly I don't control how their database is set up. Downgrading php versions isn't an option. Anyone have any ideas?

  • Inserting asyncronously into Oracle, any benefits?

    - by Karl Trumstedt
    I am using ODP.NET for loading data into Oracle. I am bulking inserts into groups of a 1000 rows each call. Is there any performance benefits in calling my load method asynchronously? So say I want to insert 10000 rows, instead of making 10 calls synchronously I make 10 calls asynchronously. My database is using ASSM right now but otherwise plenty of freelists are used of course. The database server has several cores as well. My initial tests seem to point to a performance increase, but maybe there is something I cannot see? Potential deadlock or contention issues? Of course, there is added complexity in handling transactions and such doing my load this way.

  • How do I effectively store a connection string in machine.config only?

    - by Scott Bedwell
    We are moving to an environment with multiple engines of MS SQL running on the same server (a test engine and a production engine). We also have separate test and production web servers, and would like for our asp.net applications to "magically" use the test database engine on the test web server and the production database engine on the production web servers. We would like to store the connection strings in machine.config rather than in web.config, but when we put it in machine.config, visual studio's IDE (particularly with datasets) does not recognize that the machine.config contains the connection. Does anyone know of a solution for displaying these machine.config connection strings in visual studio, or of a different solution that would accommodate for this? Thanks.

  • Hibernate, select by id or unique column

    - by Nican
    I am using hibernate for Java, and I want to be able to select users by id or by name from the database. Nice thing about Hibernate is that it caches the result by id, but I seem to be unable to make it cache by name. static Session openSession = Factory.openSession(); public static User GetUser(int Id) { return (User) openSession.get(User.class, new Integer(Id)); } public static User GetUser( String Name ){ return (User) openSession.createCriteria( User.class ). add( Restrictions.eq("username", Name) ). uniqueResult(); } If I use GetUser(1) many times, hibernate will only show that it executed the first time. But every time I use GetUser("user1"), hibernate shows that it is executing a new query to database. What would be the best way to have the string identifier be cached also?

  • Improving MySQL Update Query Efficiency

    - by Russell C.
    In our database tables we keep a number of counting columns to help reduce the number of simple lookup queries. For example, in our users table we have columns for the number of reviews written, photos uploaded, friends, followers, etc. To help make sure these stay in sync we have a script that runs periodically to check and update these counting columns. The problem is that now that our database has grown significantly the queries we have been using are taking forever to run since they are totally inefficient. I would appreciate someone with more MySQL knowledge than myself to recommend how we can improve it's efficiency: update users set photos=(select count(*) from photos where photos.status="A" AND photos.user_id=users.id) where users.status="A"; If this were a select statement I would just use a join but I'm not sure if that is possible with update. Thanks in advance for your help!

  • Why can't I pass in a uniqueidentifier/GUID to a stored procedure

    - by chobo2
    Hi I have this SP USE [TestDB] GO /****** Object: StoredProcedure [dbo].[sp_test] Script Date: 06/12/2010 11:47:27 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE PROCEDURE [dbo].[sp_test] @id uniqueidentifier AS BEGIN select * from TestTbl where ProductId= @id END I then went to the SP with ms sql 2005 and clicked execute. It comes up with a box where I entered in the GUID. I copied and pasted it straight from my test database. I get this error. Msg 102, Level 15, State 1, Line 5 Incorrect syntax near 'cac671b'. So why can't I sent in GUIDs? even ones that are copied right from the database and must be valid as they where allowed into the db.

    I'm creating a ASP MVC application. And because of the complex authorization i'm trying to build my own login system. (So i'm not using asp membership providers, and related classes). Now i'm able to create new accounts in the database with hashed passwords. But how do i keep track that a user is logged in. Is generating a long random number and putting this with the userID in the database and cookie enough? Sorry for my rather bad english! Ty in advance :)

  • output all data from db to a php page

    Hi, I'm a real beginner with PHP & mysql. Just for studying and for a simple example at school I would like to work this simple query and possibly output all the rows (or maybe even one) to a very basic output on a php page: <?php $user= "root"; $host="localhost"; $password=""; $database = "PetCatalog"; $cxn = mysqli_connect($host,$user,$password,$database) or die ("couldn’t connect to server"); $query = "SELECT * FROM Pet"; $result = mysql_query($cxn,$query) or die ("Couldn’t execute query."); $row = mysqli_fetch_assoc($result); echo "$result"; ?> this is the error message i've been getting: Warning: mysql_query() expects parameter 1 to be string, object given in C:\xampplite\htdocs\myblog\query.php on line 18 Couldn’t execute query. What should I do? Thanks!

  • Using multiple databases within one application (ASP.NET MVC, LINQ to SQL)

    - by Alex
    I have a web application made for several groups of people not connected with each other. Instead of using one database for all of them, I'm thinking about making separate databases. This will improve the speed of the queries and make me free from checking to what group the user belongs. But since I'm working with LINQ to SQL, my classes are explicitly connected with the databases, so I will have to make separate DataContexts for all of the databases. So how can I solve this problem? Or should I just not bother and use one database only?

  • Finding out event that called a CGI script

    - by Acorn
    What I want is to be able to make my CGI script do different things depending on what action initiated the calling of the script. For example, if one button is pressed, a database is cleared. If another button is pressed, a form is submitted and that data is added to the database. Should I be doing something like adding the name of the form/button to the end of the POST data submitted in jQuery and then .poping it off in the script? Or is there some other data that's already sent in the POST that I could get from FieldStorage that would give me the information I need to decide what the script should do when it's called? And what if I wasn't using javascript? Would I have to have a hidden field that gets submitted with the name of the form/button? Or is it best to use a different target script for each button on a page?
