  • How can I dump my MS SQL Server Database Schema to a human readable & printable format?

    - by Kyle West
    I want to generate something like the following: LineItems Id ItemId OrderId Price Orders Id CustomerId DateCreated Customers Id FirstName LastName Email I don't need all the relationships, the diagram that will never print correctly, the metadata, anything. Just a list of the tables and their columns in a simple text format. Has anyone done this before? Is there a simple solution? Thanks, Kyle

  • What is the query string of a BlazeDS request?

    - by dacracot
    I have a Tomcat service running on localhost:8080 and I have installed BlazeDS. I created and configured a simple hello world application like this... package com.adobe.remoteobjects; import java.util.Date; public class RemoteServiceHandler { public RemoteServiceHandler() { //This is required for the Blaze DS to instantiate the class } public String getResults(String name) { String result = “Hi ” + name + “, the time is : ” + new Date(); return result; } } With what query string can I invoke RemoteServiceHandler to my Tomcat instance via just a browser? Something like... http://localhost:8080/blazeds/?xyz

    - by acidzombie24
    I have a string like a=6&id=99 (i might store it in html as 'a=6&id=99' however thats not what js will see).

Part 2: How do i convert that object back to a query string? it would probably be trivial code that i can write.

  • Ruby on Rails: How to sanitize a string for SQL when not using find and other built-in methods?

    - by williamjones
    I'm trying to sanitize a string that involves user input without having to resort to manually crafting my own possibly buggy regex if possible. There are a number of methods in Rails that can allow you to enter in native SQL commands, how do people escape user input for those? The question I'm asking is a broad one, but in my particular case, I'm working with a column in my Postgres database that Rails does not natively understand as far as I know, the tsvector, which holds plain text search information. Rails is able to write and read from it as if it's a string, however, unlike a string, it doesn't seem to be automatically escaping it when I do things like vector= inside the model. For example, when I do model.name='::', where name is a string, it works fine. When I do model.vector='::' it errors out: ActiveRecord::StatementInvalid: PGError: ERROR: syntax error in tsvector: "::" "vectors" = E'::' WHERE "id" = 1 This seems to be a problem caused by lack of escaping of the semicolons, and I can manually set the vector='\:\:' fine. I also had the bright idea, maybe I can just call something like: ActiveRecord::Base.connection.execute "UPDATE medias SET vectors = ? WHERE id = 1", "::" However, this syntax doesn't work, because the raw SQL commands don't have access to find's method of escaping and inputting strings by using the ? mark. This strikes me as the same problem as calling connection.execute with any type of user input, as it all boils down to sanitizing the strings, but I can't seem to find any way to manually call Rails' SQL string sanitization methods. Can anyone provide any advice?

  • How do I match complete XML objects in a string?

    - by cyclotis04
    I'm attempting to find complete XML objects in a string. They have been placed in the string by an XmlSerializer, but may or may not be complete. I've toyed with the idea of using a regular expression, because it seems like the kind of thing they were built for, except for the fact that I'm trying to parse XML. I'm trying to find complete objects in the form: <?xml version="1.0"?> <type> <field>value</field> ... </type> My thought was a regex to find <?xml version="1.0"?><type> and </type>, but if a field has the same name as type, it obviously won't work. There's plenty of documentation on XML parsers, but they seem to all need a complete, fully-formed document to parse. My XML objects can be in a string surrounded by pretty much anything else (including other complete objects). hw<e>reR@lot$0fr@ndm&nchrs%<?xml version="1.0"?><type><field>...</field>...</type>@ndH#r$omOre!!>nuT6erjc?y!<?xml version="1.0"?><type><field>...</field>...</type>ty!=] A regex would be able to match a string while excluding the random characters, but not find a complete XML object. I'd like some way to extract an object, parse it with a serializer, then repeat until the string contains no more valid objects.

  • How to populate List<string> with Datarow values from single columns...

    - by James
    Hi, I'm still learning (baby steps). Messing about with a function and hoping to find a tidier way to deal with my datatables. For the more commonly used tables throughout the life of the program, I'll dump them to datatables and query those instead. What I'm hoping to do is query the datatables for say column x = "this", and convert the values of column "y" directly to a List to return to the caller: private List<string> LookupColumnY(string hex) { List<string> stringlist = new List<string>(); DataRow[] rows = tblDataTable.Select("Columnx = '" + hex + "'", "Columny ASC"); foreach (DataRow row in rows) { stringlist.Add(row["Columny"].ToString()); } return stringlist; } Anyone know a slightly simpler method? I guess this is easy enough, but I'm wondering if I do enough of these if iterating via foreach loop won't be a performance hit. TIA!

    - by dario

  • In OpenRasta, how do I configure a URI where I get "the remainder of the path" as a single string?

    - by Daniel Earwicker
    Normally in OpenRasta there is some configuration like this: ResourceSpace.Has.ResourcesOfType<Customers>() .AtUri("/customers/region/{region}") ... // and so on ... where the {region} part of the path is automatically mapped to a string parameter in the handling method. So if the user hits: http://server/customers/region/emea Then the handler method is passed the string "emea". As well as doing this, I'd like to register a handler with something like this: ResourceSpace.Has.ResourcesOfType<Customers>() .AtUri("/someotherthing/*") ... // and so on In this imaginary syntax, the asterisk would mean "take the rest of the path, including slashes, to be a single string parameter to pass to the handling method". And so if the user hits: http://server/someotherthing/how/about/this?that=other Then my handler method receives a string parameter: how/about/this?that=other Is such a thing possible in OpenRasta? In Sinatra (Ruby) I'd use a regular expression to do exactly this.

  • If it is possible to auto-format code before and after a source control commit, checkout, diff, etc.

    - by dennisjtaylor
    If it is possible to auto-format code before and after a source control commit, checkout, diff, etc. does a company really need a standard code style? It feels like standard coding style debates that have been raging since programming began like "put the bracket on the following line" or "properly indent your (" are no longer essential. I realize in languages where white space matters the diff will have to consider it but for languages where the style is a personal preference is there really a need to worry about it anymore?

  • What is the best way to format Django urls for two parameters, either of which are optional?

    - by Parker
    I'm designing a gallery application for viewing vehicle pictures and there are two parameters: Manufacturer Vehicle type Right now you can view either, but not both. Urls go like so: /manufacturer/# /type/# Where # is an ID number. How/can I format my URLs so it can accept both? My current solution is to do: /both/#/# but this requires some retooling since the application doesn't know when you want to filter by both. Any insight would be appreciated.

  • Can a BufferedImage be written to file any format?

    - by ncoder
    Is it correct that if we have a BufferedImage object in java, we could potentially write it out in ANY format using ImageIO.write (if we have a Writer object for the same)? I tried writing a BufferedImage object into a jpg file, it outputted an empty image file however when i tried writing it in to a png file, it worked fine.

  • How to easily pass a very long string to a worker process under Windows?

    - by sharptooth
    My native C++ Win32 program spawns a worker process and needs to pass a huge configuration string to it. Currently it just passes the string as a command line to CreateProcess(). The problem is the string is getting longer and now it doesn't fit into the 32K characters limitation imposed by Windows. Of course I could do something like complicating the worker process start - I use the RPC server in it anyway and I could introduce an RPC request for passing the configuration string, but this will require a lot of changes and make the solution not so reliable. Saving the data into a file for passing is also not very elegant - the file could be left on the filesystem and become garbage. What other simple ways are there for passing long strings to a worker process started by my program on Windows?

  • Objective-C - How To Remove Characters From a String?

    - by iAm
    I have a UILable that has a formatted String (formatted for currency), so there is a dollar sign, $21.34. In the core data entity the attribute is of a type double, I am using an NSDecimalNumber to save to the database. self.purchase.name = self.nameTextField.text; NSString *string = self.amountLabel.text NSDecimalNumber *newAmount = [[NSDecimalNumber alloc] initWithString:string]; NSLog(@"%@", string); // THIS RETURNS NaN, because of dollar sign i think NSManagedObjectContext *context = self.purchase.managedObjectContext; NSError *error = nil; if (![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } Anyway, I need this to not be NaN, so my thinking is to remove the dollar sign, but i do not know how to do that, or perhaps there is a better way to accomplish my goal.

  • How to regex match a string of alnums and hyphens, but which doesn't begin or end with a hyphen?

    - by Shahar Evron
    I have some code validating a string of 1 to 32 characters, which may contain only alpha-numerics and hyphens ('-') but may not begin or end with a hyphen. I'm using PCRE regular expressions & PHP (albeit the PHP part is not really important in this case). Right now the pseudo-code looks like this: if (match("/^[\p{L}0-9][\p{L}0-9-]{0,31}$/u", string) and not match("/-$/", string)) print "success!" That is, I'm checking first that the string is of right contents, doesn't being with a '-' and is of the right length, and then I'm running another test to see that it doesn't end with a '-'. Any suggestions on merging this into a single PCRE regular expression? I've tried using look-ahead / look-behind assertions but couldn't get it to work.
