metadata

问题 I want to clone the shell of a Snowflake database (metadata only, no data). Is this possible? I have checked the documentation and haven't found a solution. 回答1: If you're just trying to get an empty shell of an existing database, you could clone the entire database, and then script out a truncate of all of the tables that exist in the database. The clone doesn't add any data, and the truncate would be very quick on the clone (while not affecting the original tables). 来源： https:/

问题 Not all that familiar with XSD, I wonder if it is possible to do the following: <xs:group name="SomeGroup"> <xs:sequence> <xs:element name="Groupingcode" type="OurType" origin="DB" /> <xs:element name="Description" type="StringType" origin="XML" /> To explain: I have an XSD schema file. I need to generate an XML file according to the XSD (this part works fine) containing database data. However, some elements need additional data to be able to find the proper field to get from the database.

问题 I write lots of little test apps on my devices. Is there some metadata I can add to the app so it appears more readily in Spotlight searches? For instance, I made a laundry timer app named Lavado Can I make it appear in Spotlight searches when I search for "timer" or "laundry"? This is not for the Apple App Store, just on my devices. 回答1: Spotlight searches both names as they appear in SpringBoard (your home screen) and their full App Store names. So if your application full name is "Lavado

问题 On iOS 4.2 when I use UIImagePickerController to let the user select a image from the photo library these are the dictionary keys that are returned to me: 2011-03-02 13:15:59.518 xxx[15098:307] didFinishPickingMediaWithInfo: info dictionary: { UIImagePickerControllerMediaType = "public.image"; UIImagePickerControllerOriginalImage = "<UIImage: 0x3405d0>"; UIImagePickerControllerReferenceURL = "assets-library://asset/asset.JPG?id=1000000050&ext=JPG"; } Using one or more of these keys, how can I

问题 I have DAL (model first entity framework 4.1) and Service which is using it in separate projects. Everything was working fine, but after some minor changes (for example I generated model from database) it stoppedd working. I am now getting metadata exception. After many hours of research I downloaded ILSpy and checked that inside DAL.dll there are no resources. My connection string looks like: metadata=res://*/DataModel.TerminalRegistryModel.csdl| res://*/DataModel.TerminalRegistryModel.ssdl|

问题 I'm using Drews Metadata Extractor for Java to extract IPTC-keywords from a JPEG Image. Works good so far. I assigned the keywords using Adobe Bridge. Unfortunately, Bridge supports keywords longer than 64 chars but the metadata extractor library only reads the first 64 chars of the String. Are there any ideas of how to read the whole keyword? (max. 128 chars) PS: It's not possible to shorten the Keywords. 回答1: If you have a sample image I can test this with, I'll give it a shot. You can open

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I was looking for something to help me parse general meta-tags from websites similar to this github project I found for open graph data. Here's a demo app. Basically, I'd like to be able to have a user input a URL from a news site and have it retrieve from that the Title, Desc, etc., leaving as little work

问题 I have some site metadata I'd like to be changeable... for example, in my application, if the sysadmin didn't want to use the "Inventory" portion of the site, he/she could turn it off, and it would disappear from the main site. So I was thinking, maybe I could make a table in my database called "meta", and insert values (or tuples) there! Then, if a module got turned off, the script would update the row, and set "module x" to 0, and I'd be done with it, right? Except it seems like an awful
