  • Example of moving from MySQL to NoSQL?

    - by OverTheRainbow
    Hello, For a Facebook-like site, ie. which is write-intensive and delivers user-customized pages, I'd like to build a prototype to investigate whether the document-centric NoSQL architecture would be a good alternative to sharding and reduce the load on the single master (+ multiple slaves) that we currently use and is the bottleneck. Does someone know of a good article that would give actual, simple examples of going from a relational layout in MySQL to a NoSQL layout? Thank you.

  • when to index on multiple keys in mongodb

    - by Evan
    say I have an Item document with :price and :qty fields. I sometimes want to find all documents matching a given :price AND :qty, and at other times it will be either :price on its own or :qty on its own. I have already indexed the :price and :qty keys, but do I also need to create a compound index on both together or are the single key indexes enough?

  • Shortcodes and Custom Fields

    - by user1429400
    How do I get shortcodes to process properly in custom fields? I've tried using the code below, but I cannot figure out where to place it ("button" is the name of the field): <?php if ( get_post_meta($post->ID, 'button', true) ) echo do_shortcode(get_post_meta($post->ID, 'button', $single = true)); ?> As of now, the shortcode is working in the sense that the button is displaying, but the shortcode text is displaying where the "buy now" button is supposed to be. See screenshot: http://i.imgur.com/41vsr.png

  • Reset SQL variable inside SELECT statement

    - by Jason McCreary
    I am trying to number some rows on a bridge table with a single UPDATE/SELECT statement using a counter variable @row. For example: UPDATE teamrank JOIN (SELECT @row := @row + 1 AS position, name FROM members) USING(teamID, memberID) SET rank = position Is something like this possible or do I need to create a cursor? If it helps, I am using MySQL 5.

  • dojo dgrid tree, subrows in wrong position

    - by Ventura
    I have a dgrid, working with tree column plugin. Every time that the user click on the tree, I call the server, catch the subrows(json) and bind it. But when it happens, these subrows are show in wrong position, like the image bellow. The most strange is when I change the pagination, after go back to first page, the subrows stay on the correct place. (please, tell me if is possible to understand my english, then I can try to improve the text) My dgrid code: var CustomGrid = declare([OnDemandGrid, Keyboard, Selection, Pagination]); var grid = new CustomGrid({ columns: [ selector({label: "#", disabled: function(object){ return object.type == 'DOCx'; }}, "radio"), {label:'Id', field:'id', sortable: false}, tree({label: "Title", field:"title", sortable: true, indentWidth:20, allowDuplicates:true}), //{label:'Title', field:'title', sortable: false}, {label:'Count', field:'count', sortable: false} ], store: this.memoryStore, collapseOnRefresh:true, pagingLinks: false, pagingTextBox: true, firstLastArrows: true, pageSizeOptions: [10, 15, 25], selectionMode: "single", // for Selection; only select a single row at a time cellNavigation: false // for Keyboard; allow only row-level keyboard navigation }, "grid"); My memory store: loadMemoryStore: function(items){ this.memoryStore = Observable(new Memory({ data: items, getChildren: function(parent, options){ return this.query({parent: parent.id}, options); }, mayHaveChildren: function(parent){ return (parent.count != 0) && (parent.type != 'DOC'); } })); }, This moment I am binding the subrows: success: function(data){ for(var i=0; i<data.report.length; i++){ this.memoryStore.put({id:data.report[i].id, title:data.report[i].created, type:'DOC', parent:this.designId}); } }, I was thinking, maybe every moment that I bind the subrows, I could do like a refresh on the grid, maybe works. I think that the pagination does the same thing. Thanks. edit: I forgot the question. Well, How can I correct this bug? If The refresh in dgrid works. How can I do it? Other thing that I was thinking, maybe my getChildren is wrong, but I could not identify it. thanks again.

  • Delphi plugin for pasting text constants in source code?

    - by mjn
    Inserting (pasting from clipboard) of text constants in the Delphi code editor requires some manual "postprocessing" ... split up long text into multiple lines (and insert the string concatenation symbol) escape quotes (replace single quotes with double quotes) enclose the string with quotes keep original white space (leadinng blanks, line feeds) Is there a IDE plugin available which helps to reduce these manual steps?

  • Dynamic swappable Data Access Layer

    - by Andy
    I'm writing a data driven WPF client. The client will typically pull data from a WCF service, which queries a SQL db, but I'd like the option to pull the data directly from SQL or other arbitrary data sources. I've come up with this design and would like to hear your opinion on whether it is the best design. First, we have some data object we'd like to extract from SQL. // The Data Object with a single property public class Customer { private string m_Name = string.Empty; public string Name { get { return m_Name; } set { m_Name = value;} } } Then I plan on using an interface which all data access layers should implement. Suppose one could also use an abstract class. Thoughts? // The interface with a single method interface ICustomerFacade { List<Customer> GetAll(); } One can create a SQL implementation. // Sql Implementation public class SqlCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Query SQL db and return something useful // ... return new List<Customer>(); } } We can also create a WCF implementation. The problem with WCF is is that it doesn't use the same data object. It creates its own local version, so we would have to copy the details over somehow. I suppose one could use reflection to copy the values of similar fields across. Thoughts? // Wcf Implementation public class WcfCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Get date from the Wcf Service (not defined here) List<WcfService.Customer> wcfCustomers = wcfService.GetAllCustomers(); // The list we're going to return List<Customer> customers = new List<Customer>(); // This is horrible foreach(WcfService.Customer wcfCustomer in wcfCustomers) { Customer customer = new Customer(); customer.Name = wcfCustomer.Name; customers.Add(customer); } return customers; } } I also plan on using a factory to decide which facade to use. // Factory pattern public class FacadeFactory() { public static ICustomerFacade CreateCustomerFacade() { // Determine the facade to use if (ConfigurationManager.AppSettings["DAL"] == "Sql") return new SqlCustomrFacade(); else return new WcfCustomrFacade(); } } This is how the DAL would typically be used. // Test application public class MyApp { public static void Main() { ICustomerFacade cf = FacadeFactory.CreateCustomerFacade(); cf.GetAll(); } } I appreciate your thoughts and time.

  • Oracle - Return shortest string value in a set of rows

    - by Sridhar
    Hi, I'm trying to write a query that returns the shortest string value in the column. For ex: if ColumnA has values ABCDE, ZXDR, ERC, the query should return "ERC". I've written the following query, but I'm wondering if there is any better way to do this? BTW, the query should return a single value. select distinct ColumnA from ( select ColumnA, rank() over (order by length(ColumnA), ColumnA) len_rank from TableA where ColumnB = 'XXX' ) where len_rank <= 1 Thank you.

  • What does [a|b|c] evaluate to in Prolog?

    - by Ambrose
    The pipe operator in prolog returns one or more atomic Heads and a Tail list. ?- [a,b,c] = [a,b|[c]]. true. Nesting multiple pipes in a single match can be done similar to this: ?- [a,b,c] = [a|[b|[c]]]. true. What does the statement [a|b|c] infer about a, b and c?
