When logging in, start typing How can I correct this behavior when displaying this data?

  • Looking for solution to persist rows sequence in a database table that allow efficient reordering at

    - by Chau Chee Yang
    I have a database table. There is a field name "Sequence" that indicate sequence when user presents the rows in report or grid visually. When the rows are retrieved and presented in a grid, there are few UI gadget that allow user to reorder the rows arbitrary. The new sequence will be persist in database table when user commit the changes. Here are some UI operations: Move to first Move to last Move up 1 row Move down 1 row multi-select rows and move up or down multi-select rows and drag to new position For operation like "Move to first" or "Move to Last", it usually involve many rows and the sequence those rows would need to be updated accordingly. This may not be efficient enough at runtime. It is a common practice to use INTEGER as sequence's data type. Other solution is using "DOUBLE" or "FLOAT" that could overcome the mass update of row sequence but we will face problem if we reach the limit of precision.

  • Carrierwave upload to a tmp dir before saving to database

    - by user827570
    I'm trying to build a visual editor where users can click an image they are presented with an image upload form once the upload is done I use ajax to return the image and insert it back into the page. But the above method inserts the image straight into the database but I want users to be able to visualize the image before the image is inserted into the database. So I was wondering if the image using carrierwave could be uploaded to a temp location, sent back to the user and then when the user saves the page the image is moved into the permanent location. Here's what I have so far. def edit_image @page = Page.find(1) @page.update_attributes(params[:page]) @page.save return :text => @page.file end But this is what I want to achieve def temp_image #uploads received image to a temp location #returns image to the user end And once the user clicks save def save #moves the file in the temp folder to the permanent location end Cheers

    This is a question that originated from this question by Jamie. I thought I'll check Dougman's answer. What's happening here? A restore? select created from dba_users where username = 'SYS'; select min(created) FROM dba_objects; select created from v$database; CREATED ------------------------- 10-SEP-08 11:24:44 MIN(CREATED) ------------------------- 10-SEP-08 11:24:28 CREATED ------------------------- 18-DEC-09 15:49:00 Created from v$database is more than one year later than creation date of user SYS and SYS' objects.

  • How to Practically Split Values from CSV File into MySQL Database

    - by Ryan
    Let's suppose I have the following line in a CSV file (I removed the header row in this example): "500,000",2,50,2,90000 I have a PHP script read the CSV file, break the file into individual lines, and store each line in an array called $linearray. Then, I use a foreach loop to look at each line individually. Within the foreach loop, I break the line into separate variables using the following function: $line = str_replace("'","\'",$line); From here, I insert the values into separate columns within a MySQL database. The script works. The values are inserted into a database, but I run into a problem. I want: "500,000" | 2 | 50 | 2 | 90000 But I get this: "500 | 000" | 2 | 50 | 2 | 90000 The script isn't smart enough to understand it should skip commas within quotation marks. Do you know how I can alter my script to make sure I get the output I'm looking for? Thanks.

  • How can I get started with PHPUnit, where my class construct requires a preconfigured db connection?

    - by Ben Dauphinee
    I have a class that uses a lot of database internally, so I built the constructor with a $db handle that I am supposed to pass to it. I am just getting started with PHPUnit, and I am not sure how I should go ahead and pass the database handle through setup. public function setUp(/*do I pass a database handle through here, using a reference? aka &$db*/){ $this->_acl = new acl; } public function __construct(Zend_Db_Adapter_Abstract $db, $config = array()){

  • Class design when working with dataset

    - by MC
    If you have to retrieve data from a database and bring this dataset to the client, and then allow the user to manipulate the data in various ways before updating the database again, what is a good class design for this if the data tables will not have a 1:1 relationship with the class objects? Here are some I came up with: Just manipulate the DataSet itself on the client and then send it back to the database as is. This will work though obviously the code will be very dirty and not well-structured. Same as #1, but wrap the dataset code around classes. What I mean is that you may have a class that takes a dataset or a datatable in its constructor, and then provides public methods and properties to simplify the code. Inside these methods and properties it will be reading or manipulating the dataset. To update the database afterwards will be easy because you already have the updated dataset. Get rid of the dataset entirely on the client, convert to objects, then convert back to a dataset when needing to update the database. Is there any good resources where I can find information on this?

  • MonoTouch & SQLite - Cannot open database after previous successful connections

    - by Tanis Draven
    I am having difficulty in reading data from my SQLite database from MonoTouch. I can read and write without any difficulty for the first few screens and then suddenly I am unable to create any further connections with the error: Mono.Data.Sqlite.SqliteException: Unable to open the database file at Mono.Data.Sqlite.SQLite3.Open (System.String strFilename, SQLiteOpenFlagsEnum flags, Int32 maxPoolSize, Boolean usePool) [0x0007e] in /Developer/MonoTouch/Source/mono/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0/SQLite3.cs:136 at Mono.Data.Sqlite.SqliteConnection.Open () [0x002aa] in /Developer/MonoTouch/Source/mono/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0/SQLiteConnection.cs:888 I ensure that i dispose and close every connection each time i use it but still i have this problem. For example: var mySqlConn = new SqliteConnection(GlobalVars.connectionString); mySqlConn.Open(); SqliteCommand mySqlCommand = new SqliteCommand(SQL, mySqlConn); mySqlCommand.ExecuteNonQuery(); mySqlConn.Close(); mySqlCommand.Dispose(); mySqlConn.Dispose(); I'm guessing that I'm not closing the connections correctly. Any help would be greatly appreciated.

  • How to setup port forwarding from my Webserver (apache) to my Database server (mysql)

    - by karman888
    Hello again guys, and thank you for your help so far. Here is my problem: I have two remote dedicated servers, one webserver that runs apache, and one db server that runs mysql. The apache server is visible on the internet of course, but the second server is only visible to the apache server because they are connected with LAN. I need to connect to the remote mysql server through internet from my home-pc , but only apache server is visible to my home-pc. How can i setup port-forwarding from my apache server to the mysql server so i will be able to "see" the mysql server from my home-pc? This question is a follow-up from my first question Connect to remote mysql server from my application. Problem is that Mysql server is on LAN in which you answered me and helped me a lot by telling me to do "port-forwarding". I looked over the internet, and i cant find a good how-to to do port-forwarding. I'm an experienced programmer, but have little experience on hardware and networks. I can understand though what must be done, so i just need a litle help to sort things out :) I hope you can help me guys, Thank you in advance p.s. machine that Apache is running is on CentOS, mysql server also CentOS. p.s2 webserver runs WebHostManager i dont know if that makes any difference or it can be made easily through this, i just mention it :)

  • Is this a valid backup strategy for MongoDB?

    - by James Simpson
    I've got a single dedicated server with a MongoDB database of around 10GB. I need to do daily backups, but I can't have downtime with the database. Is it possible to use a replica set on a single disk (with 2 instances of mongod running on different ports), and simply take the secondary one offline and backup the data files to an offsite storage such as S3 (journaling is turned on)? Or would using master/slave be better than a replica set? Is this viable, and if so, what potential problems could I have? If not, how do I conceptualize this to work?

  • Zend without Database

    - by dbemerlin
    Hi, i googled for an hour now but maybe my Google-Fu is just too weak, i couldn't find a solution. I want to create an application that queries a service via JSON requests (all data and backend/business logic is stored in the service). With plain PHP it's simple enough since i just make a curl request, json_decode the result and get what i need. This already works quite well. A request might look like this: Call http://service-host/userlist with body: {"logintoken": "123456-1234-5678-901234"} Get Result: { "status": "Ok", "userlist":[ {"name": "foo", "id": 1}, {"name": "bar", "id": 2} ] } Now we want to get that into the Zend Framework since it's a hobby project and we want to learn about Zend. The problem is that all information i could find use a Database. Is there even a way to create a Zend Project that does not use a Database? And how can i write a model that represents the actions instead of objects and object-relations?

  • NoSQL vs. MySQL when scalability is irrelevant

    - by Bryan Ward
    Recently I have read a lot about different NoSQL databases and how they are being effectively deployed by some major websites out there. I'm starting a project in which I think the schema-free nature of a database such as MongoDB would be tremendously useful. Everything I have read though seems to indicate that the main advantage of a NoSQL database is scalability. Is choosing a NoSQL database for the schema-free design just as legitimate a design decision as that of scalability?

  • Which is better for multi-use auth, MySQL, PostgreSQL, or LDAP?

    - by Fearless
    I want to set up an Oracle Linux 6 server that gives users secure IMAP email (with dovecot), Jabber IM, FTP (with vsftpd), and calDav. However, I want each user logon to be able to authenticate all services (e.g. Joe Smith signs up once for a username and password that he can use for email, ftp, and his calendar). My question is, which database service will be best suited for that application? Also, is there a way to link the database with the preexisting server shell logins (e.g. so I can read the root account's LogCheck emails on a different device)?

  • Add version control to existing SQL Server database

    - by ederbf
    I am part of a development team currently working with a database that does not have any kind of source control. We work with SQL Server 2008 R2 and have always managed the DB directly with SSMS. It now has ~340 tables and ~1600 stored procedures, plus a few triggers and views, so it is not a small DB. My goal is to have the DB under version control, so I have been reading articles, like Scott Allen's series (http://bitly.com/9cJmGR) and many old SO related questions. But I am still unable to decide on how to proceed. What I'm thinking of is to script the database schema in one file, then procedures, triggers and views in one file each. Then keep everything versioned under Mercurial. But of course, every member of the team can access SSMS and directly change the schema and procedures, with the possibility that any of us can forget to replicate those changes in the versioned files. What better options are there? And, did I forget any element worth having source control of?

  • database change after pressing 'X' button

    - by Anup Prakash
    What i know:- We can use Ajax to change database from javascript. So whenever we press the 'X' button on title bar it calls "onbeforeunload" event. And by this event we can change the database. But in my case, i want to change the status of user only when user click on 'X' button. Not in case of changing the page. As because changing the page is unloading the page. and closing the page is also unloading the page(As much i know). Is there any way to differentiate between closing the page and moving from one page to other page? I want to use it for changing the status of user(i.e. login/logout), whenever he presses cross button. I don't want to set status "logout" when user changes the page. I want to set status "logout" when user 'X' the button. Plese help me.
