metadata

问题 I'm trying to use the mutagen module to read the metadata of an mp3 file. The problem is that the module is expecting a local mp3 file, but my mp3 files are on a remote server. This is the line in the module that raises an error when I send a remote mp3 URL as the first parameter. fp = file(f, "rb") How can I alter this line of code so that it can open a remote file (e.g. http://remotedomain.com/file.mp3 ) in rb mode ? 回答1: fp = urllib2.urlopen("http://remotedomain.com/file.mp3") binary mode

问题 Generally to get the meta data from SQL Server backup files, we need to use TSQL commands like restore headeronly or restore filelistonly . However, there are some third party tools can read this information directly from the backup files, like this one http://www.yohz.com/sqlbakreader_details.htm. Since this tool don't have a command line version, which makes it less useful. I want to know whether there are some ways that I can read this data directly. Thanks. 回答1: The .bak file is a

问题 As I understand, ffmpeg by default places all meta info at the end of the file when generating mp4s. Source: http://www.stoimen.com/blog/2010/11/12/how-to-make-mp4-progressive-with-qt-faststart/ What I need to do is create the video, one frame at a time and then stream it. This is impossible if the header info is at the 'end' of the file. But is it possible to move this to the beginning or otherwise work around this? I would definitely prefer to not have to switch to another library and use

问题 I've figured out how to query for some metadata for example calling this in my query: <td>" + record['created'].value + "</td> <-- populates some table data But this comes back undefined which confuses me because the CloudKit dashboard has a value for Created By (as part of the automatic Metadata that is created with each record.) How do I query for the ID/UUID as well as get the response in a HTML/JS-readable manner? 回答1: After fetching one or more records with CloudKit.js you'll notice you

问题 I was mildly surprised recently to discover that my carefully crafted xml comments weren't showing up in intellisense for my colleagues. Having always used the associated assemblies with project references, I hadn't realised that you had to export the .xml document as well to access this information. This led me to wondering how the .Net framework intellisense works. If I understand correctly, the .xml files must be hidden away somewhere in a special folder? But my main question is about

问题 What would be the URL for the newly set up SAML SSO's metadata URL, or how could I download this in XML format from WSO2 Identity Server (version 4.6.0) acting as IdP? Thanks, Tamas 回答1: AFAIK there is no option to auto-generate metadata files for IS. You have to manually write the metadata file. An example is as follows, taken from this blog post. <md:entitydescriptor entityid="https://localhost:9443/samlsso" validuntil="2023-09-23T06:57:15.396Z" xmlns:ds="http://www.w3.org/2000/09/xmldsig#"

问题 I am working on a programming tutorial project, and I want the sample source code for this tutorial to have a meaningful revision history, relevant to the tutorial's progress. Inevitably, I won't get all the tutorial commits perfectly right the first time, and I don't want that revision history cluttered with commits where I modify the tutorial's commits in a meta way. I think this means that I want two levels of version control: an inner one that is relevant to users of the tutorial, and an

问题 How do you get a list of the input parameters for a stored procedure using metadata in SQL Server 2005? I want to do a SELECt on it and then iterate through the variable names. 回答1: start here select * from information_schema.PARAMETERS where SPECIFIC_NAME = 'YourStoredProcedureName' order by ORDINAL_POSITION look for parameter_name, data_type, parameter_mode 回答2: SQL-Server native way: select type_name(system_type_id) as type_name , parameter_id , name , max_length from sys.parameters where

问题 I am trying to create a single query for getting information from the main table (WordPress user table), and the user meta table. If you're not familiar with WP DB architecture: wp_users holds basic user information and their IDs, wp_usermeta holds the ID, meta_key, and meta_value. Let's say I want to get all users that have certain meta_keys and meta_values. This is the query I currently have (generated via PHP based on available meta_keys): SELECT ID, user_email, user_login, first_name.meta

问题 I have a MySQL database that, I would like to annotate by adding comments to all of the columns, From what I read on the MySQL documentation, it is necessary to include the data type and all attributes when changing any single one of these. For example, I must type ALTER TABLE `dbname`.`tablename` CHANGE COLUMN `columnname` `columnname` INT(11) NULL DEFAULT NULL COMMENT 'this is my comment`; It would be much faster for me to avoid having to restate the column info for each change, for example
