  • MySQL Select names with last names ending with certain letter

    - by Brian
    I have a MySQL database with a field Name which contains full names. To select all people with last names ending in a particular letter, let's say A for this example, I use the following query: SELECT * FROM db WHERE Name LIKE '% A%'. However, this also selects users who have a middle name starting with A. Is there anyway to alter this query so that only a last name ending in A will be selected?

  • Why doesn't nHibernate support LIMIT when doing "join fetch"?

    - by HeavyWave
    In nHibernate, if you do an HQL query with "join fetch" to eagerly load a child collection, nHibernate will ignore SetMaxResults and SetFirstResult and try to retrieve every single item from the database. Why? This behavior is specific to HQL, as ICriteria supports eager loading (with an outer join, though) and LIMIT. There are more details here http://www.lesnikowski.com/blog/index.php/nhibernate-ignores-setmaxresults-in-sql/ .

  • Crystal reports .net visual studio 2008 bundled edition

    - by DeveloperChris
    I have a serious issue with crystal reports. when run in my development environment or debugged on my local machine it works fine. but when the application is published to a windows server 2003 it has the dreaded "The report you requested requires further information" Message I have had no luck trying to get rid of this message Anybody know what I can try? DC Here is a bunch more info. I use a placeholder in the aspx page and then set the user/password and database in the codebehind I could not get it to work with a dataset and found that I had to assign odbc connection in the cr designer. and then in the code behind change the above details as required. This is done because the same report can get the data from 3 different databases (live development and training) protected override void Page_Load(object sender, EventArgs e) { base.Page_Load(sender, e); CrystalReportSource1.ReportDocument.Load(Server.MapPath(@"~/Reports/Report5asp.rpt")); CrystalReportViewer1.ReportSource = ConfigureCrystalReports(CrystalReportSource1.ReportDocument,CrystalReportViewer1); // parameters CrystalReportViewer1.ParameterFieldInfo.Clear(); AddParameter("DIid", _app.Data["DIid"], CrystalReportViewer1.ParameterFieldInfo); AddParameter("EEid", _app.Data["EEid"], CrystalReportViewer1.ParameterFieldInfo); AddParameter("CTid", _app.Data["CTid"], CrystalReportViewer1.ParameterFieldInfo); } public ReportDocument ConfigureCrystalReports(ReportDocument report, CrystalReportViewer viewer) { String _connectionString = _app.ConnectionString(); String dsn = _app.DSN(); SqlConnectionStringBuilder SConn = new SqlConnectionStringBuilder(_connectionString); TableLogOnInfos crtableLogoninfos = new TableLogOnInfos(); TableLogOnInfo crtableLogoninfo = new TableLogOnInfo(); ConnectionInfo crConnectionInfo = new ConnectionInfo(); crConnectionInfo.ServerName = dsn;// SConn.DataSource; crConnectionInfo.DatabaseName = SConn.InitialCatalog; crConnectionInfo.UserID = SConn.UserID; crConnectionInfo.Password = SConn.Password; crConnectionInfo.Type = ConnectionInfoType.SQL; crConnectionInfo.IntegratedSecurity = false; foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in report.Database.Tables) { crtableLogoninfo = CrTable.LogOnInfo; crtableLogoninfo.ConnectionInfo = crConnectionInfo; CrTable.ApplyLogOnInfo(crtableLogoninfo); } return report; } As stated this works fine on my XP machine used for development when deployed on winserver 2003 I get the error DC Some interesting additional information I moved the development to my home machine so I could work on the problem this weekend. So now I am developing debugging and testing on the same machine! In VS2008 I can edit and preview the reports with no problems If I fire up the debugger I can view the reports in the browser with no problems But if I publish the website to another folder on the same machine and fire up IIS and try to browse to a report I get the aforementioned error. All else works as expected. IIS runs under different permissions than VS2008 so perhaps its something to do with that, but I have tried lots of different permissions and cannot get it to run. DC

    What would be the simplest implementation of an A/B testing system running on App engine? I'm especially keen towards performance implications of using Datastore for back-end (with looong query times), and database design.

  • svg diagrams using python

    - by Zitrax
    I am looking for a library to generate svg diagrams in python (I fetch data from a sql database). I have found python-gd, but it has not much documentation and last update was in 2005 so I wonder if there are any other libraries that are good for this purpose. I am mostly thinking about simple line graphs, something like this:

  • Delphi / ADO : how to get result of Execute() ?

    - by mawg
    I have declared AdoConnection : TADOConnection; and successfully connected to the default "mysql" database (so, no need to pass that code). Now, taking baby steps to learn, I would like to AdoConnection.Execute('SHOW DATABASES', cmdText); which seems to work ok, in the sense that it doesn't throw an exception, but I am such a n00b that I don't know how I can examine the result of the command :-/ Halp!

  • Is Zend Framework a total waste of my time?

    - by Citizen
    Ok, I'm about 50% done with the "30 minute" quickstart guide from Zend. I must be missing something, because this seems like a total waste of time. The point of this quickguide is to create a guestbook, something I could do in 5 minutes with regular naked non-framework php. Here's my path to zend framework: c:/program files/wamp/www/_zend/ Here's my path to my quickstart project: c:/program files/wamp/www/_zend/bin/quickstart/ I have a number of questions at this point: http://framework.zend.com/docs/quickstart/create-a-model-and-database-table 1: I'm running the command line to run my database loading script. I get an error stating the it can't find the Zend/AutoLoader.php becuase my path to the zend library is wrong. I followed all of the steps. I defined the path to my zend library in the main config file, but for some reason, its defined again in my db loader. In all of these scripts that they have me load, it points the relative path to the zend library as being /../library Problem is, there's nothing in that folder. To get to my actual zend folder, you'd need to be (relatively) /../../../../library Which brings me to my 2nd question: 2: Where the #$#$ is the main Zend files supposed to be? The install directions were basically "put it wherever you want", when the real answer (after a bunch of errors and wasted time was) was "put it somewhere so that its really easy to type the full path a thousand times in command line" and "it also better be in a runnable place on your webserver since its going to create your quickstart application in a subdirectory within zend". Which brings us to the third question 3: Am I supposed to have this libary in both the parent core Zend (wamp/_zend/library) AND my application (quickstart/library)? 4: If that is the case, it seems like a ton of wasted files to be uploading. I'd like to use Zend to create products that my customers will download. 5 megs of overhead seems like a bit much. Zend claims you can use these library components separately, but it looks to me like I'm going to have to upload them every time. Which leads to the next question: 5: It appears that perhaps Zend is more for a single application that is not supposed to be distributed. Is this not the case? 6: According to their default file structure everything but my /public folder would be above public_html on my server if I wanted this to rest on my TLD. I would need to rename every reference of /public/ to /public_html/, or am I missing something else?

  • FileMaker Pro vs CiviCRM

    - by Silvana Procopio
    Hello, I would like some input about these two softwares since we are trying to change our current Access database, which has brought many problems and is completely outdated (it was built 10 years ago). These are the 2 options we have in mind and being a non-profit organization (20 employees), it's quite a big decision in particular in terms of costs. Due to the type of business, we will need several hours of development too. Any feedback will be greatly appreciated. Thank you so much in advance, Silvana

  • Codeigniter Best Practices for Model functions

    - by user270797
    Say my application has a "Posts" model, and one of the function is add_post(), it might be something like: function add_post($data) { $this-db-insert('posts',$data); } Where $data is an array: $data = array ('datetime'='2010-10-10 01:11:11', 'title'='test','body'='testing'); Is this best practice? It means if you use that function you need to know the names of the database fields where as my understanding of OOP is that you shouldnt need to know how the method works etc etc

    - by alistair.mp
    Hello, We're running a large site at the moment which has a dedicated VPS for it's database server which is running MySQL and nothing else. At the moment all four CPU cores are running at close to 100% all of the time but the memory usage sticks at around 268MB out of an available 4096MB. I'm wondering what we can do to better utilise the memory and reduce the CPU load by tweaking MySQL's settings? Here is what we currently have in my.cnf: http://pastie.org/private/hxeji9o8n3u9up9mvtinbq Thanks

  • JSP/Servlet CRUD form with special input field based on join table relationship

    - by user1701467
    There's database with a bunch of tables that are joined with join tables. E.g. Members and Division are joined with MembersDivisions table. JSP/Servlet login functionality has been developed, but now the CRUD functionality needs to be implemented and I was unable to find any tutorials about it, especially involving the join table(when creating new division you can add members to it, or add more to the existing one). Maybe someone could, theoretically, explain how to do the Division part of the CRUD web form?

By right with 18 columns, there should be 17 comma delimiters, but the comma delimiter for the last column (which all null) never been written to the CSV. Does anyone ever encounter this and how to handle this?

  • How to use EntityFramework connection string for Elmah?

    - by Andrii Kovalchuk
    In ELMAH for logging errors to the database you can write: <errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="EducoparkEntities"/> However, if I use EntityFramework, this doesn't work because the connection string for EF contains metadata as well: <add name="EducoparkEntities" connectionString="metadata=res://*/EducoparkData.csdl|res://*/EducoparkData.ssdl|res://*/EducoparkData.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=(Local);Initial Catalog=...;User Id=...;Password=...;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient"/> So, how can I use the EntityFramework connection string in Elmah?

  • Sensible Doctrine Expression and Zend_Auth setCredentialTreatment()

    - by takeshin
    How to create reasonable expression to store password in database using Doctrine and Zend_Auth::setCredentialTreatment()? I don't want to use md5() and the code must be portable, and with salt. I would call this not easy one to guess: setCredentialTreatment("SHA1(CONCAT(username, SHA1(CONCAT(username, ?)))"); but it is not portable to all databases. Seems that Doctrine_Expression has only md5 expression portability.
