  • What causes subprocess.call to output blank file when attempting db export with mysqldump?

    - by caldazar
    I am having some problems using subprocess.call to export a database using mysqldump. I'm using Python 3.1 installed on Windows 7. from time import gmtime, strftime import subprocess DumpDir = "c:/apps/sqlbackup/"; DumpFile = "mysqldump-" + strftime("%Y-%m-%d-%H-%M-%S", gmtime()) + ".sql"; params = [r"mysqldump --user root --password=mypassword --force --flush-privileges --compress --comments mydatabase --result-file=" + DumpDir + DumpFile]; subprocess.call(params, shell=True); The above code causes a blank file to be created in the DumpDir. I've tried getting python to print the command so I can test it via the CMD prompt using: print(subprocess.list2cmdline(params)); If I paste the output to the CMD prompt and execute it, everything works fine. Any ideas? I'm new to Python, so I am sure the answer is simple but I've tried so many variations to get this working that I just can't figure this out.

  • ISBNs are used as primary key, now I want to add non-book things to the DB - should I migrate to EAN

    - by fish2000
    I built an inventory database where ISBN numbers are the primary keys for the items. This worked great for a while as the items were books. Now I want to add non-books. some of the non-books have EANs or ISSNs, some do not. It's in PostgreSQL with django apps for the frontend and JSON api, plus a few supporting python command-line tools for management. the items in question are mostly books and artist prints, some of which are self-published. What is nice about using ISBNs as primary keys is that in on top of relational integrity, you get lots of handy utilities for validating ISBNs, automatically looking up missing or additional information on the book items, etcetera, many of which I've taken advantage. some such tools are off-the-shelf (PyISBN, PyAWS etc) and some are hand-rolled -- I tried to keep all of these parts nice and decoupled, but you know how things can get. I couldn't find anything online about 'private ISBNs' or 'self-assigned ISBNs' but that's the sort of thing I was interested in doing. I doubt that's what I'll settle on, since there is already an apparent run on ISBN numbers. should I retool everything for EAN numbers, or migrate off ISBNs as primary keys in general? if anyone has any experience with working with these systems, I'd love to hear about it, your advice is most welcome.

  • How to access GMAIL for storage in custom CRM SQL Server DB?

    - by Optimal Solutions
    I have a client who wants his custom-written CRM to be able to access his sales people's emails so that, effectively, a history of email conversations between customer and salesperson is stored inside the CRM's database. The CRM is written in VB 2008 and the database is SQL Server 2008. The only email these people use, in the shop and on the road, is GMAIL. Each sales person has their own GMAIL address. Thats how they operate. If they're on the road and respond to a customer's email inquiry about a product, they would like that email conversation to be stored in a table in the database. I think thats the part I cant wrap my head around. How to get access to the email data (knowing the user id and password) and doing so from VB 2008

  • Application Design: Single vs. Multiple Hits to the DB

    - by shyneman
    I'm building a service that performs a set of configured activities based on the type of request that it receives. Each activity involves going to the database and retrieving/updating some kind of information. The logic for each activity can be generalized and re-used across different request types. The activities may need to participate in a transaction for the duration of the servicing the request. One option, I'm considering is having each activity maintain its own access to DAL/database. This fully encapsulates the activity into a stand-alone re-usable piece, but hitting the database multiple times for one request doesn't seem like a viable option. I don't really know how to easily implement the concept of a transaction across the multiple activities here either. The second option is to encapsulate ALL the activities into one big activity and hit the database once. But this does not allow re-use and configuration of these activities for different requests. Does anyone have any suggestions and input about what should be the best way to approach my problem? Thanks for any help.

  • What's wrong with this code? Values not saved to db

    - by Scott B
    Been trying to get this code to work for several days now to no avail. I'm at wits end. I've managed, with the code below, to create a customized category picker widget that appears on the PAGE editor. However, for the life of me, I cannot get the checked categories to save. function my_post_options_box() { if ( function_exists('add_meta_box') ) { //add_meta_box( $id, $title, $callback, $page, $context, $priority ); add_meta_box('categorydiv', __('Page Options'), 'post_categories_meta_box_modified', 'page', 'side', 'core'); } } //adds the custom categories box function post_categories_meta_box_modified($post) { $noindexCat = get_cat_ID('noindex'); $nofollowCat = get_cat_ID('nofollow'); if(in_category("noindex")){ $noindexChecked = " checked='checked'";} else {$noindexChecked = "";} if(in_category("nofollow")){ $nofollowChecked = " checked='checked'";} else {$noindexChecked = "";} ?> <div id="categories-all" class="ui-tabs-panel"> <ul id="categorychecklist" class="list:category categorychecklist form-no-clear"> <li id='category-<?php echo $noindexCat ?>' class="popular-category"><label class="selectit"><input value="<?php echo $noindexCat ?>" type="checkbox" name="post_category[]" id="in-category-<?php echo $noindexCat ?>"<?php echo $noindexChecked ?> /> noindex</label></li> <li id='category-<?php echo $nofollowCat ?>' class="popular-category"><label class="selectit"><input value="<?php echo $noindexCat ?>" type="checkbox" name="post_category[]" id="in-category-<?php echo $nofollowCat ?>"<?php echo $nofollowChecked ?> /> nofollow</label></li> <li id='category-1' class="popular-category"><label class="selectit"><input value="1" type="checkbox" name="post_category[]" id="in-category-1" checked="checked"/> Uncategorized</label></li> </ul> </div> <?php }

  • Using mod-rewrite to conditionally select existing file in a subdirectory based on Host header?

    - by Kevin Hakanson
    I'm working through a problem where I want to select a different static content file based on the incoming Host header. The simple example is a mapping from URLs to files like this: www.example.com/images/logo.gif - \images\logo.gif skin2.example.com/images/logo.gif - \images\skin2\logo.gif skin3.example.com/images/logo.gif - \images\skin3logo.gif I have this working with the following RewriteRules, but I don't like how I have to repeat myself so much. Each host has the same set of rules, and each RewriteCond and RewriteRule has the same path. I'd like to use the RewriteMap, but I don't know how to use it to map the %{HTTP_HOST} to the path. <VirtualHost *:80> DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" ServerName www.example.com ServerAlias skin2.example.com ServerAlias skin3.example.com RewriteEngine On RewriteCond %{HTTP_HOST} skin2.example.com RewriteCond %{DOCUMENT_ROOT}$1/skin2/$2 -f RewriteRule ^(.*)/(.*) $1/skin2/$2 [L] RewriteCond %{HTTP_HOST} skin3.example.com RewriteCond %{DOCUMENT_ROOT}$1/skin3/$2 -f RewriteRule ^(.*)/(.*) $1/skin3/$2 [L] </VirtualHost> The concept behind the rules is if the same filename exists in a subdirectory for that host, use it instead of the direct targeted file. This uses host based subdirectories at the lowest level, and not a top level subdirectory to separate content.

  • Letting users trial your web app before sign-up: sessions or temp db?

    - by Mat
    I've seen a few instances now where web applications are letting try them out without you having to sign-up (though to save you need to of course). example: trial at http://minutedock.com/ I'm wondering about doing this for my own web app and the fundamental question is whether to store their info into sessions or into a temp user table? The temp user table would allow logging and potentially be less of a hit on the server correct? Is there a best practice here?

  • Sanitize HTML before storing in the DB or before rendering? (AntiXSS library in ASP.NET)

    - by user102533
    I have an editor that lets users add HTML that is stored in the database and rendered on a web page. Since this is untrusted input, I plan to use Microsoft.Security.Application.AntiXsSS.GetSafeHtmlFragment to sanitize the HTML. Should I santiize before saving to the database or before rendering the untrusted input into the webpage? Is there an advantage in including the AntiXSS source code in my project instead of just the DLL? (Maybe I can customize the white list?) Which class file should I look in for actual implementation of the GetSafeHtmlFragment

  • Writing a custom auth system (like the default django auth system), use it to generate tables in DB

    - by dotty
    Hay all, I've been reading up on middleware and how to use it with a context object. I want to write a simple middleware class which i can use on my own applications, it will essentially be a cut down version of the django one. The problem i seem to have is that if i have INSTALLED_APPS = ('django.contrib.my_auth') in the settings file, all is well. I've also added MIDDLEWARE_CLASSES = ('django.contrib.my_auth.middleware.MyAuthMiddleware') in it and everything is fine. My question is, how would i make my middleware automatically generate tables from a models.py module, much like how the django auth does when i run manage.py syncdb? thanks

  • Is DB logging more secure than file logging for my PHP web app?

    - by iama
    I would like to log errors/informational and warning messages from within my web application to a log. I was initially thinking of logging all of these onto a text file. However, my PHP web app will need write access to the log files and the folder housing this log file may also need write access if log file rotation is desired which my web app currently does not have. The alternative is for me to log the messages to the MySQL database since my web app is already using the MySQL database for all its data storage needs. However, this got me thinking that going with the MySQL option is much better than the file option since I already have a configuration file with the database access information protected using file system permissions. If I now go with the log file option I need to tinker the file and folder access permissions and this will only make my application less secure and defeats the whole purpose of logging. Is this correct? I am using XAMPP for development and am a newbie to LAMP. Please let me know your recommendations for logging. Thanks.

  • Sqlite. How to create an index in attached DB?

    - by kappa
    I have a problem with adding index to memory database attached to main database. 1) I open the database (F) from file 2) Attach the :memory: (M) database 3) Create tables in database M 4) Copy data from F to M I would also like to create an index in database M, but don't know how to do that. This code creates index but in F database: sQuery = "CREATE INDEX IF NOT EXISTS [INDID] ON [PANEL]([ID] ASC);"; I tried to add the name qualifier before table name like this: sQuery = "CREATE INDEX IF NOT EXISTS [INDID] ON [M.PANEL]([ID] ASC);"; but SQLite returns with message that column main.M.PANEL does not exist. What can I do?

  • Generated sql from LINQ to SQL

    - by Muhammad Kashif Nadeem
    Following code ProductPricesDataContext db = new ProductPricesDataContext(); var products = from p in db.Products where p.ProductFields.Count > 3 select new { ProductIDD = p.ProductId, ProductName = p.ProductName.Contains("hotel"), NumbeOfProd = p.ProductFields.Count, totalFields = p.ProductFields.Sum(o => o.FieldId + o.FieldId) }; Generated follwing sql SELECT [t0].[ProductId] AS [ProductIDD], (CASE WHEN [t0].[ProductName] LIKE '%hotel%' THEN 1 WHEN NOT ([t0].[ProductName] LIKE '%hotel%') THEN 0 ELSE NULL END) AS [ProductName], ( SELECT COUNT(*) FROM [dbo].[ProductField] AS [t2] WHERE [t2].[ProductId] = [t0].[ProductId] ) AS [NumbeOfProd], ( SELECT SUM([t3].[FieldId] + [t3].[FieldId]) FROM [dbo].[ProductField] AS [t3] WHERE [t3].[ProductId] = [t0].[ProductId]) AS [totalFields] FROM [dbo].[Product] AS [t0] WHERE (( SELECT COUNT(*) FROM [dbo].[ProductField] AS [t1] WHERE [t1].[ProductId] = [t0].[ProductId] )) > 3 Why is this CASE statement for ProductName and because of this instead of ProductName i am just getting 0 in my result set. It should generate sql like following, (where ProductName like '%hotel%' SELECT [t0].[ProductId] AS [ProductIDD], [ProductName], ( SELECT COUNT(*) FROM [dbo].[ProductField] AS [t2] WHERE [t2].[ProductId] = [t0].[ProductId] ) AS [NumbeOfProd], ( SELECT SUM([t3].[FieldId] + [t3].[FieldId]) FROM [dbo].[ProductField] AS [t3] WHERE [t3].[ProductId] = [t0].[ProductId]) AS [totalFields] FROM [dbo].[Product] AS [t0] WHERE (( SELECT COUNT(*) FROM [dbo].[ProductField] AS [t1] WHERE [t1].[ProductId] = [t0].[ProductId] )) > 3 AND t0.ProductName like '%hotel%' Thanks.

  • Is there any framework for Windows Forms, DB driven application development/prototyping?

    - by dolzenko
    I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

  • Update table without using cursor and on date

    - by Muhammad Kashif Nadeem
    Please copy and run following script DECLARE @Customers TABLE (CustomerId INT) DECLARE @Orders TABLE ( OrderId INT, CustomerId INT, OrderDate DATETIME ) DECLARE @Calls TABLE (CallId INT, CallTime DATETIME, CallToId INT, OrderId INT) ----------------------------------------------------------------- INSERT INTO @Customers SELECT 1 INSERT INTO @Customers SELECT 2 ----------------------------------------------------------------- INSERT INTO @Orders SELECT 10, 1, DATEADD(d, -20, GETDATE()) INSERT INTO @Orders SELECT 11, 1, DATEADD(d, -10, GETDATE()) ----------------------------------------------------------------- INSERT INTO @Calls SELECT 101, DATEADD(d, -19, GETDATE()), 1, NULL INSERT INTO @Calls SELECT 102, DATEADD(d, -17, GETDATE()), 1, NULL INSERT INTO @Calls SELECT 103, DATEADD(d, -9, GETDATE()), 1, NULL INSERT INTO @Calls SELECT 104, DATEADD(d, -6, GETDATE()), 1, NULL INSERT INTO @Calls SELECT 105, DATEADD(d, -5, GETDATE()), 1, NULL ----------------------------------------------------------------- I want to update @Calls table and need following results. I am using the following query UPDATE @Calls SET OrderId = ( CASE WHEN (s.CallTime > e.OrderDate) THEN e.OrderId END ) FROM @Calls s INNER JOIN @Orders e ON s.CallToId = e.CustomerId and the result of my query is not what I need. Requirement: As you can see there are two orders. One is on 2010-12-12 and one is on 2010-12-22. I want to update @Calls table with relevant OrderId with respect to CallTime. In short If subsequent Orders are added, and there are further calls then we assume that a new call is associated with the most recent Order Note: This is sample data so this is not the case that I always have two Orders. There might be 10+ Orders and 100+ calls. Note2 I could not find good title for this question. Please change it if you think of any better. Thanks.

  • What's the proper way to use sqlite on the iPhone?

    - by Elliot Chen
    Hi, Experts: Can you please give some suggestions on sqlite using on the iPhone? Within my application, I use a sqlite DB to store all local data. Two methods can be used to retrieve those data during running time. 1, Load all the data into memory at initialization stage. (More memory used, less DB open/close operation needed) 2, Read corresponding records when necessary, free the occupied memory after using. (Good habit for memory using, but much DB open/close operations needs). I prefer to use method 2, but not sure whether too many DB opening/closing operations could affect app's efficiency. Or do you think I can 'upgrade' method 2 by opening DB when app launches and closing DB when app quits? Thanks for your suggestions very much!
