  • how to invoke function writen in a validation.php and stroe all function name in database.

    - by saint
    Respected all, i'm in trouble. I created a file with name validation.php and store all my validation functionality in this file with different function names like, check_textbox(parm1, pram2, pram3, pram4) { // Definition here } check_chkBox(parm1, pram2) { // Definition here } and so on.....! then i created a table in mysql with the name tbValidation and stored all the function name with parameters in a table. the record stored in table look like as: interfaceid---------- functionNameWithReturnValue 1 ------------ check_textbox(parm1, pram2, pram3, pram4) = 1 2 ------------ check_textbox(parm1, pram2, pram4) = 0 3 ------------ check_textbox(parm1, pram2, pram4) = 1) AND (check_chkBox(parm1, pram2)=0) when i fetch record from database i want to invoke those functions that store in validation.php $data = mysql_fetch_array($drow); if($db->row_count > 0) { // when i fetch row one from database. I used this one but not working // @ $data[0] have value "check_textbox(parm1, pram2, pram3, pram4) = 1" if($data[0]) { // Do this } } How i can do this task...? :(

  • ORM framework that extends base class with database-implementation.

    - by aioobe
    I have a game consisting of a client / server + a webpage. A central notion in both client and game-/webserver is an Account. Accounts are stored in a database thus I'm in need of some ORM and recently had a look at Hibernate and Cayenne. My understanding however, is that both frameworks provide an "DatabaseBackedAccount"-class which I extend with my other Account methods. My problem is that the Account class is reused heavily on the client side, and I would obviously not want to include database-related code on the client implementation. My current solution is to have an Account class (shared by server and client) and extend this with a DatabaseBackedAccount (overriding setter-methods and providing a commit method) on the server side. I find this quite natural and nice, however I've had to implement all gory sql-details and ORM myself. Is there any way to "turn the table" in any existing ORM framework, so that the generated classes extend my existing class?

  • What is the advantage of using static methods in Python?

    - by Curious2learn
    I ran into unbound method error in python with the code class Sample(object): '''This class defines various methods related to the sample''' def drawSample(samplesize,List): sample=random.sample(List,samplesize) return sample Choices=range(100) print Sample.drawSample(5,Choices) After reading many helpful posts here, I figured how I could add @staticmethod above to get the code working. I am python newbie. Can someone please explain why one would want to define static methods? Or, why are not all methods defined as static methods. Thanks in advance.

  • Alternatives to connect to ORACLE database server without install the Oracle client.

    - by Salvador
    i am looking for an Delphi component to connect to an ORACLE database server in an direct way without install the oracle client. i knew the Oracle Data Access (ODAC) from DevArt. there are any other component with this capability? ODAC offers two connection modes to the Oracle server: connection through the Oracle Call Interface in Client mode and direct connection over TCP/IP in Direct mode. ODAC-based database applications are easy to deploy, do not require installation of other data provider layers. Thanks in advance.

  • Translate model fields' attributes from a Database with Django?

    - by Luiz C.
    I'm trying to create a Model that has fields that have the following attributes translatable: verbose_name and choices. I can easily do this by tagging the strings and using the i18l middleware. The problem is that I don't want to define the translation in po/mo files. Is there a way to pull this data from a database table? If so, any examples? There are some options out there that offer model content translation. That is not my case. I need to translate the verbose_name, choices and error_messages from database.

  • GAE uploading to database - or - how to create big dictionary in GAE?

    - by Koran
    Hi, I have a GAE application. A new request is to have a huge database to store many items for some functionality. The database needs to populated every week or so - and populating it is done by querying many external links which overall takes around 1-2 hours. So, doing it via GAE Cron is now out of the question. Another option I was thinking was to create it in external server and then uploading it to GAE DB. Is it possible to upload the data created externally to GAE DB straightaway? The question is because there will be close to 10 M items in it, so adding items individually to a DB is not going to work due to 30 second time limit. Thanks K

  • Search filenames in MySQL database table restricted by filetype?

    - by ju
    Hello I have a MySQL database that I replicate from another server. The database contains a table with this columns ID, FileName and FileSize In the table there are more than 4'000'000 records. I want to make fast a search in FileName (varchar) column I found that I can use for this Sphinx search engine. The problem is that I want to restrict searches by filetype. Do I have to and how (trigers?) to extract file extensions for all rows? May be I have to create another table (because this one is replicated) and join them in 1:1 relation? Can you give me some advices please :)

  • How does one declare the type of an Android preference?

    - by David R.
    I have a preferences.xml that looks like this: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <EditTextPreference android:name="Sample" android:enabled="true" android:persistent="true" android:summary="Sample" android:defaultValue="3.0" android:title="Sample" android:key="sample" /> </PreferenceScreen> When I do sp.getString("sample", "3.0"), it works fine and returns a string, but it shouldn't be a string, it should be a float. Running sp.getFloat("sample", 3.0f) throws a ClassCastException because it is a string. What should I put in the XML so that the preference is stored as a float?

  • mysql data read returning 0 rows from class

    - by Neo
    I am implementing a database manager class within my app, mainly because there are 3 databases to connect to one being a local one. However the return function isn't working, I know the query brings back rows but when it is returned by the class it has 0. What am I missing? public MySqlDataReader localfetchrows(string query, List<MySqlParameter> dbparams = null) { using (var conn = connectLocal()) { Console.WriteLine("Connecting local : " + conn.ServerVersion); MySqlCommand sql = conn.CreateCommand(); sql.CommandText = query; if (dbparams != null) { if (dbparams.Count > 0) { sql.Parameters.AddRange(dbparams.ToArray()); } } MySqlDataReader reader = sql.ExecuteReader(); Console.WriteLine("Reading data : " + reader.HasRows + reader.FieldCount); return reader; /* using (MySqlCommand sql = conn.CreateCommand()) { sql.CommandText = query; if (dbparams != null) { if (dbparams.Count > 0) { sql.Parameters.AddRange(dbparams.ToArray()); } } MySqlDataReader reader = sql.ExecuteReader(); Console.WriteLine("Reading data : " + reader.HasRows + reader.FieldCount); sql.Parameters.Clear(); return reader; }*/ } } And the code to get the results query = @"SELECT jobtypeid, title FROM jobtypes WHERE active = 'Y' ORDER BY title ASC"; //parentfrm.jobtypes = db.localfetchrows(query); var rows = db.localfetchrows(query); Console.WriteLine("Reading data : " + rows.HasRows + rows.FieldCount); while (rows.Read()){ } These scripts return the following : Connecting local : 5.5.16 Reading data : True2 Reading data : False0

  • Getting my webapp to be database agnostic with Hibernate...

    - by JellyHead
    So the ultimate in scope-creep came in the other day: since we're using Hibernate, could we make our webapp run on Oracle as well as MySQL, interchangably? I thought this would be a simple case of changing hibernate.cfg.xml so that instead of explicity stating MySQL-specific options, it would reference a JNDI datasource, allowing the application to build regardless of the database we intend to deploy to. Then changing to a different database would simply mean changing the separate datasource configuration in JBoss, Jetty, WebLogic etc. Is this realistic? Well, I got as far as setting that up in Jetty, but What's tripping me up right now is error about the hibernate.dialect not having been set in hibernate.cfg.xml. But If I set the dialect there, then my app is still going to be built in either MySQL or Oracle flavours, which is not really what I want. Either I'm trying to attempt the impossible or I've missed something fundamentally obvious... anyone else had a similar problem (and subsequent solution/workaround)?

  • does this raw sql only one trip to the database or many trips?

    - by Álvaro García
    I gues that I have this sql: string strTSQL = "Begin TRAN delete from MyTable where ID = 1"; string strTSQL = ";delete from MyTable where ID = 2"; string strTSQL = ";delete from MyTable where ID = 3 COMMIT"; using(Entities dbContext = new Entities()) { dbCntext.MyTable.SQLQuery(strTSQL); } This use a transaction in the dataBase, so all the commands are executed or no one. But how I execute it through EF, it does only one trip to the database or many? Thanks.

  • Excel macro to change external data query connections - e.g. point from one database to another

    - by Rory
    I'm looking for a macro/vbs to update all the external data query connections to point at a different server or database. This is a pain to do manually and in versions of Excel before 2007 it sometimes seems impossible to do manually. Anyone have a sample? I see there are different types of connections 'OLEDB' and 'ODBC', so I guess I need to deal with different formats of connection strings?

  • Trying to grab several random videos from database, but it just shows the same one all the time.

    - by Birk
    Hi guys, I'm trying to grab several random videos from my database, and have them show on a page. However, it just keeps on grabbing the same video rather than several different ones. So I end up with 5 of the same video rather than 5 different ones. Here's the grab random PHP code file... and after it is the template output file. //===================================================== // Random | Previous | Next //===================================================== $show['random'] = $db->quick_fetch( "SELECT file_id, title, title_seo, category_id, thumb FROM files WHERE files.category_id = '".$show['main']['category_id']."' AND files.verified=1 ORDER BY RAND() LIMIT 0,1; "); Here's the template CSS html thingy code I have this pasted 5 times to show 5 random videos <td valign="top" width="53%"><? $sql="select * from files ORDER BY rand() limit 0,5"; $res=@mysql_query($sql); $data=@mysql_result($res,0,'filename'); $id=@mysql_result($res,0,'file_id'); $title=@mysql_result($res,0,'title'); $title2=str_replace(" ", "-",$title); $path="{$siteurl}/media/{$file.random.file_id}/{$file.random.title_seo}/"; $img="{$siteurl}/thumbs/{$file.random.thumb}"; echo " {$file.random.title}"

  • How to implement automatic reflection of direct SQL Updates of the underlying database, in an ActiveRecord in Ruby on Rails ?

    - by Vadim Eisenberg
    Hello ! I am new to Ruby on Rails and I have a (maybe naive) question: I want to implement reflection of direct SQL Updates of the underlying database in an ActiveRecord (and finally in the generated html). By "direct updates" I mean updating the database bypassing the ActiveRecord methods, for example by MySQL console. I guess here MySQL triggers could be used that would call some stored procedure that would cause the appropriate ActiveRecord to be reloaded. Is there some automatic handling of this scenario in ActiveRecord/Ruby on Rails ? Did somebody implement this scenario ? Can somebody recommend using other MVC frameworks to reflect direct changes in mapped databases ?

  • Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

    - by Jay
    I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?

  • How can I make an Access database readable from the web while it is open in MS Access?

    - by djdilicious
    I have a website using ASP with an MS Access DB back-end for storing mainly blog posts. My company has a very long software approval process so I am stuck with what I have (i.e. I must use Access). I use server-side javascript to retrieve posts stored in the database using OLEDB calls. Everything works fine except that I cannot read any tables from the database when it is open in the MS Access program. The page displays an error message about the file being in use. This could lead to significant downtime while I am doing any work within Access. How can I make the file readable by my ASP application while it is open in Access?

  • Best Ruby ORM for Wrapping around Legacy MSSQL Database?

    - by Technocrat
    Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support mssql through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in MSSQL. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the MSSQL app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with MSSQL but never to do anything quite like this. Any suggestions?

  • Confusion using MYSQLI

    - by user1020069
    I just started using mysqli API for PHP. Apparently, every time an object of the class MYSQLI is instantiated, it can setup a connection to the database as it connects to the server unlike mysql_connect, which connects to the server first and then you are required to specify the database to query. Now this is a good problem if the db exists, in my case, the db does not exist on the first ever connection to the server/execution of the problem, hence I must connect without specifying the database, which is fine, since the msyqli constructor does not make this database mandatory. My challenge is essentially, how do I check if the database exists before attempting the first connection. The only way to really do this would be to establish a conection to the server and then use the result of the following query to gauge if the database exists: SELECT COUNT(*) AS `exists` FROM INFORMATION_SCHEMA.SCHEMATA WHERE SCHEMATA.SCHEMA_NAME="dbname" ; If this returns true, then the database exists, but now the challenge is how do I get the mysqli object to query this database rather than having to prefix the name of the database in the query. Thanks much
