  • MySQL date query only returns one year, when multiple exist

    - by Bowman
    I'm a part-time designer/developer with a part-time photography business. I've got a database of photos with various bits of metadata attached. I want to query the database and return a list of the years that photos were taken, and the quantity of photos that were taken in that year. In short, I want a list that looks like this: 2010 (35 photos) 2009 (67 photos) 2008 (48 photos) Here's the query I'm using: SELECT YEAR(date) AS year, COUNT(filename) as quantity FROM photos WHERE visible='1' GROUP BY 'year' ORDER BY 'year' DESC Instead of churning out all the possible years (the database includes photos from 2010-2008), this is the sole result: 2010 (35 photos) I've tried a lot of different syntax but at this point I'm giving in and asking for help!

  • Free and Simple Hosting Solution with DB Support?

    - by darren
    Hi everyone I have compiled an sqlite database that I would like to make public. I want to provide a very simple webpage that has a few form elements which are used to query the database. Does anybody know of a free hosting solution that would provide me with free web and database functionality? I am familiar with Google App Engine and that would work but I don't want to spend time using their custom storage scheme. I'm looking for something free that I can put together very quickly. Thanks for any suggestions.

  • Connecting Ingres from C

    - by avesus
    I need to connect to an Ingres supplied demodb through OpenAPI, both Ingres and C application running on windows. What i have done: Created a "node" in the Ingres Network Utility named "usernode". created user accounts in the Ingres installation (named "user" password "user") and in the Windows user management (the same creds.) Granted necessary privileges to the user in the database. In C code i have called IIapi_connect() function with an IIAPI_CONNPARM structure. Used members: co_target = "usernode::demodb", co_username = "user", co_password = "user" But IIapi_connect() call returns an error: "User provided a vnode as part of the database name (vnode::dbname), but connection information for that vnode is missing. Enter connection information for the vnode using NETUTIL." Anybody knows something that is a weird concept "node"? What are the minimum steps (in the database administration and the function parameters passing) necessary for the successful connect?

  • Why is the dictionary debug visualizer less useful in Visual Studio 2010?

    - by Kevin
    I was debugging in Visual Studio 2010, which we just installed and trying to look at a dictionary in the quick watch window. I see Keys and Values, but drilling into those shows the Count and Non-Public members, Non-Public members continues the trail and I never see the values in the dictionary. I can run test.Take(10) and see the values, but why should I have to do that. I don't have VS 2008 installed anymore to compare, but it seems that I could debug a dictionary much easier. Why is it this way now? Is it just a setting I set somehow on my machine? Test code: Dictionary<string, string> test = new Dictionary<string, string>(); test.Add("a", "b");

  • upload an m4a file in flex, saving it as a blob in oracle, and retrieving metadata info from it

    - by Angus
    Hi, I currently have a FileUpload.mxml component that uploads a .m4a to an oracle database, retrieves metadata from the file and saves the metadata info in the database. to acheive this I use FileReference() and set up, amoung others, the dispatcher.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, completeHandler); So the file is posted to a php file which saves it as a blob. Once the blob is saved, the script sends a message back to flex to dispatch the upload_complete_data event. In the complete handler, the metadata is then retreived by reading the value back from the database into a custom made meta data reader. The metadata info is then saved via flex. This seems a little long winded. Has anyone else successfully achieved this using a different way?

  • PHP/Mysql issues

    - by queryne
    Php/my sql newbie question. I have a database I've imported into my local phpmyadmin. However it seems I can't access it from my a php application. The connection string seems right and when i try to authenticate user credentials to access database information, no problems. However authenticate everyone and knows when i put in fake credentials. Still it won't pull any other information from the database. For instance, once a users login they should see something like, "Hello username"... that kind of thing. At this point I see "Hello" without the username. Any ideas what i might be missing?

  • Django adminsite customize search_fields query

    - by dArignac
    Howdy! In the django admin you can set the search_fields for the ModelAdmin to be able to search over the properties given there. My model class has a property that is not a real model property, means it is not within the database table. The property relates to another database table that is not tied to the current model through relations. But I want to be able to search over it, so I have to somehow customize the query the admin site creates to do the filtering when the search field was filled - is this possible and if, how? I can query the database table of my custom property and it then returns the ids of the model classes fitting the search. This then, as I said, has to flow into the admin site search query. Thanks!

  • PHP: best practice. Do i save html tags in DB or store the html entity value?

    - by Matt
    Hi Guys, I was wondering about which way i should do the following. I am using the tiny MCE wysiwyg editor which formats the users data with the right html tags. Now, i need to save this data entered into the editor into a database table. Should i encode the html tags to their corresponding entities when inserting into the DB, then when i get the data back from the table, not have the encode it for XSS purposes but i'd still have to use eval for the html tags to format the text. OR Do i save the html tags into the database, then when i get the data back from the database encode the html tags to their entities, but then as the tags will appear to the user, i'd have to use the eval function to actually format the data as it was entered. My thoughts are with the first option, i just wondered on what you guys thought. Thanks M

  • which lightweight SQL Server type could I use on my Dev machine for a C# VS2010 project?

    - by Greg
    Hi, Which lightweight SQL Server type could I use on my Dev machine for a C# VS2010 project? (e.g. sql server express, sql server ce, full version etc). That is, I'm running on a VMWare fusion instance on my MacBook, and just want something to develop against for a C# VS2010 project. I'm planning on having a simple database (not many tables) but will use Entity Framework. I haven't used SQL Server before so a quick pointer re what is the best database admin interface/app to use for the version you recommend (e.g. to create database, tables etc).

  • Is it a good idea to use a computed column as part of a primary key ?

    - by Brann
    I've got a table defined as : OrderID bigint NOT NULL, IDA varchar(50) NULL, IDB bigint NULL, [ ... 50 other non relevant columns ...] The natural primary key for this table would be (OrderID,IDA,IDB), but this it not possible because IDA and IDB can be null (they can both be null, but they are never both defined at the same time). Right now I've got a unique constraint on those 3 columns. Now, the thing is I need a primary key to enable transactional replication, and I'm faced with two choices : Create an identity column and use it as a primary key Create a non-null computed column C containing either IDA or IDB or '' if both columns were null, and use (OrderID,C) as my primary key. The second alternative seams cleaner as my PK would be meaningful, and is feasible (see msdn link), but since I've never seen this done anywhere, I was wondering if they were some cons to this approach.

  • Rails: Converting from MySQL to PostGres breaks Geokit Distance Calculations???

    - by Kevin
    I recently switched my database from MySQL to PostGres. I also use GeoKit. When I started my app up with the new database already seeded, I get the following error: PGError: ERROR: function radians(character varying) does not exist LINE 1: ...COS(0.661045389762993)*COS(-2.12957994527573)*COS(RADIANS(ti... ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. Anyone know why this is breaking now? I know GeoKit still works because it's still performing the geocoding in the model per ticket when the database is seeded, it just won't do the distance calculations correctly.

  • How should images be stored when multiple sizes are needed?

    - by Josh Curren
    What is the best way to store images? Currently when an image is uploaded I resize it to 3 different sizes (a thumbnail, a normal size, and a large size). I save in a database a description of the image, the format, and use the id number from the database as the image name. Each size image has its own directory. Should I be storing the images in the database? Should I only be storing the larger size and generate the thumbnail as needed? Or any other ideas you have?

  • How to make a jquery datePicker button image unclickable

    - by Farzana
    I have a jquery UI datePicker in my page. I have a text box on which the date is displayed. The code is: $("#cal").datepicker({ minDate: new Date(), defaultDate: new Date(), buttonImage: '/images/calendar.gif', constrainInput: false, closeText: 'Close', showButtonPanel: true, showButtonText: 'Choose a date', buttonImageOnly : true, showOn : 'button' }); $("#till").datepicker('setDate', today); I want to disable this on some conditions. I use the following code to disable: $("#cal").datePicker('disable'); It blacks out the text box but the image is still clickable. The problem is in IE, the date picker pop up comes up but does not close when the image button associated with the date picker is clicked. I also tried to bind a onclick function with the image to make it non-clickable. But that does not work as well. How can make the date picker image button non-clickable when the date picker is disabled. Any help would be appreciated. Thanks, Farzana

  • Getting "select permission denied" when using LINQ but my account is a sysadmin

    - by Wayne M
    I have a console app that's geared to be automatically ran as a Scheduled Task. I use LINQ to SQL to pull some data out of the database, format it into a CSV and email it to a client. All of a sudden I am getting the error "SELECT permission denied for table", but the account I'm using to connect to the database (specified in my app.config file) has the "sysadmin" server role (bad programmer, I know; I'll get around to changing it to a better account later but I want to make sure it works first). I can connect directly to the SQL database using that very same account and query the table in question without a problem, it only seems to be when using the LINQ code. Any idea what would be causing this?

  • Can Tomcat provide seperate (or HTTPS only) sessions for HTTPS requests?

    - by Joe
    I have a web application which contains both secure (SSL) and non-secure pages. A user can login to the site and must appear logged-in in both the SSL and non-SSL areas. (NB. SSL isn't implemented via Tomcat, but via Apache HTTPD servers which sit in front of Tomcat - so Tomcat has no SSL configuration.) The logged-in state is currently maintained via a servlet session (using Tomcat's vanilla session management). The obvious issue with this approach is that the JSESSIONID cookie is transported over both HTTP and HTTPS connections, meaning that it's potentially possible to intercept it and hijack the session. Are there any solutions to this without rolling our own session management (i.e. does Tomcat cater for this situation)? I'm prepared to implement our own session management, but don't want to reinvent something that may already be supported.

  • SaaS Multi-tenancy Applications: How is data import/export/backup being implemented?

    - by Mark Redman
    How are applications providing import / export (or backups) of data in SaaS based multi-tenancy applications, particularly single database designs? Imports: Keeping things simple I think basic imports are useful, ie CSV to a spec (or a way of providing a mapping between CSV columns and fields in the database. Exports: In single database designs I have seen XML exports and HTML (basic sitse generated) exports of data? I would assume that XML is a better option? How does one cater for relational data? Would you reference various things within XML and provide documentation of the relationships or let users figurethis out? Are vendors providing an export/backup that can be imported back in/restored? Your comments appreciated.

  • How to show / debug PEAR::DB errors in webpage?

    - by Markus Ossi
    I am connecting to MySQL database on my webpage and have this copy-pasted code for errors: if(DB::isError($db)) die($db->getMessage()); I have the connection code in an outside file called connection.inc that I include at the beginning of my page before the DOCTYPE and html tags. For debugging purposes, how can I print the database errors on my webpage? I thought I could do something like this: echo 'Could not connect to database. The error was:' . $db->getMessage(); but this returns: Fatal error: Call to undefined method DB_mysql::getMessage()

  • What Use are Threads Outside of Parallel Problems on MultiCore Systesm?

    - by Robert S. Barnes
    Threads make the design, implementation and debugging of a program significantly more difficult. Yet many people seem to think that every task in a program that can be threaded should be threaded, even on a single core system. I can understand threading something like an MPEG2 decoder that's going to run on a multicore cpu ( which I've done ), but what can justify the significant development costs threading entails when you're talking about a single core system or even a multicore system if your task doesn't gain significant performance from a parallel implementation? Or more succinctly, what kinds of non-performance related problems justify threading? Edit Well I just ran across one instance that's not CPU limited but threads make a big difference: TCP, HTTP and the Multi-Threading Sweet Spot Multiple threads are pretty useful when trying to max out your bandwidth to another peer over a high latency network connection. Non-blocking I/O would use significantly less local CPU resources, but would be much more difficult to design and implement.

  • Do I need multiple template specializations if I want to specialize for several kinds of strings?

    - by romkyns
    For example: template<typename T> void write(T value) { mystream << value; } template<> void write<const char*>(const char* value) { write_escaped(mystream, value); } template<> void write<char*>(char* value) { write_escaped(mystream, value); } template<> void write<std::string>(std::string value) { write_escaped(mystream.c_str(), value); } This looks like I'm doing it wrong, especially the two variants for const and non-const char*. However I checked that if I only specialize for const char * then passing a char * variable will invoke the non-specialized version, when called like this in VC++10: char something[25]; strcpy(something, "blah"); write(something); What would be the proper way of doing this?
