  • Open Source - EER Modeling Tool

    - by Nick Fergis
    Is there a good open source or reasonably priced EER modeling tool for MySQL besides MySQL Workbench? I find the MySQL Workbench interface to be clunky. I would like to be able to manage my production schema beginning all design changes in the EER and propogating those out to my schema for created and altered tables. Is anyone use a tool they love to manage their environments in this way? Thanks. - Nick

  • The standard map/associative-array structure to use in flash actionscript 3?

    - by tstyle
    I'm relatively new to flash, and is confused about what I should use to store and retrieve key value pairs. After some googling I've found various map-like things to choose from: 1) Use a Object: var map:Object = new Object(); map["key"] = "value"; The problem is that it seems to lack some very basic features. For example to even get the size of map I'd have to write a util method. 2) Use a Dictionary What does this standard library class provide over the simple object? It seems silly for it to exist if it's functionally identical to Object. 3) Go download some custom HashMap/HashTable implementation from the web. I've used a lot of modern languages, and this is the first time I haven't been able to find a library implementation of an associative array within 5 minutes. So I'd like to get some best-practice advice from an experienced flash developer. Thanks!

I also checked out link and was not able to get a clue from it. I want to handle it in the report level. Thank you. NLV

  • how to store data crawled from website

    - by Richard
    I want to crawl a website and store the content on my computer for later analysis. However my OS file system has a limit on the number of sub directories, meaning storing the original folder structure is not going to work. Suggestions? Map the URL to some filename so can store flatly? Or just shove it in a database like sqlite to avoid file system limitations?

  • How to retain a row which is foreign key in another table and remove other duplicate rows?

    - by Mithril
    I have two table: A: id code 1 A1 2 A1 3 B1 4 B1 5 C1 6 C1 ===================== B: id Aid 1 1 2 4 (B doesn't contain the Aid which link to code C1) Let me explain the overall flow: I want to make each row in table A have different code(by delete duplicate),and I want to retain the Aid which I can find in table B.If Aid which not be saved in table B,I retain the id bigger one. so I can not just do something as below: DELETE FROM A WHERE id NOT IN (SELECT MAX(id) FROM A GROUP BY code, ) I can get each duplicate_code_groups by below sql statement: SELECT code FROM A GROUP BY code HAVING COUNT(*) > 1 Is there some code in sql like for (var ids in duplicate_code_groups){ for (var id in ids) { if (id in B){ return id } } return max(ids) } and put the return id into a idtable?? I just don't know how to write such code in sql. then I can do DELETE FROM A WHERE id NOT IN idtable

    I have a row of IDs in a database that has been serialized. What I'm trying to do is check those serialized IDs against a known ID to see if it should be excluded or not. for example: "SELECT * FROM mydb WHERE id = 4 AND checkID != 'an id in the serialized column' " What's the best way to go about this?

    - by Richard
    So I have this registration script: The HTML: <form action="register.php" method="POST"> <label>Username:</label> <input type="text" name="username" /><br /> <label>Password:</label> <input type="text" name="password" /><br /> <label>Gender:</label> <select name="gender"> <optgroup label="genderset"> <option value="Male">Male</option> <option value="Female">Female</option> <option value="Hermaphrodite">Hermaphrodite</option> <option value="Not Sure!!!">Not Sure!!!</option> </optgroup> </select><br /> <input type="submit" value="Register" /> </form> The PHP/SQL: <?php $username = $_POST['username']; $password = $_POST['password']; $gender = $_POST['gender']; mysql_query("INSERT INTO registration_info (username, password, gender) VALUES ('$username', '$password', '$gender') ") ?> The problem is, the username and password gets inserted into the "registration_info" table just fine. But the Gender input from the select drop down menu doesn't. Can some one tell me how to fix this, thanks.

  • What exactly is the Nullify delete rule doing?

    - by dontWatchMyProfile
    Does that mean that if I delete an managed object which has references (relationship) to some others, the relationships are removed to those others? Example: objectA references objectB and objectC. objectA gets deleted, it's relationship to objectB and objectC is set to the Nullify rule. What happens in detail?

  • How to **delete-protect** a file or folder on Windows Server 2003 and onwards using C#/Vb.Net?

    - by Steve Johnson
    Hi all, Is it possible to delete-protect a file/folder using Registry or using a custom written Windows Service in C#? Using Folder Permissions it is possible, but i am looking for a solution that even restricts the admin from deleting specific folders. The requirement is that the administrator must not be easily track the nature of protection and/or may not be able to avert it easily. Obviously all administrators will be able to revert the procedure if the technique is clearly understood. Like folder Permissions/OwnerShip Settings can easily be reset by an administrator. SO that is not an option. Folder protection software can easily be uninstalled and show clear indication that a particular folder is protected by some special kind of software. SO that too is not an option. Most antivirus programs protect folders and files in Program Dir. Windows itself doesnt allow certain files such as registry files in c:\windows\system32\config to not even copied. Such a protection is desired for folders which allowse to read and write to files but not allow deletion. Similar functionality is desired. The protection has to seemless and invisible. I do not want to use any protection features like FolderLock and Invisible secrets/PC Security and Desktop password etc. Moreover, the solution has to be something other than folder encryption. The solution has to be OS-native so ** that it may implemented ** pro grammatically using C#/VB.Net. Please help. Thanks

  • ASP.NET DynamicData: Whats happening during an update?

    - by Jens A.
    I am using ASP.NET DynamicData (based on LINQ to SQL) on my site for basic scaffolding. On one table I have added additional properties, that are not stored in the table, but are retrieved from somewhere else. (Profile information for a user account, in this case). They are displayed just fine, but when editing these values and pressing "Update", they are not changed. Here's what the properties look like, the table is the standard aspnet_Users table: public String Address { get { UserProfile profile = UserProfile.GetUserProfile(UserName); return profile.Address; } set { UserProfile profile = UserProfile.GetUserProfile(UserName); profile.Address = value; profile.Save(); } } When I fired up the debugger, I've noticed that for each update the set accessor is called three times. Once with the new value, but on a newly created instance of user, then once with the old value, again on an new instance, and finally with the old value on the existing instance. Wondering a bit, I checked with the properties created by the designer, and they, too, are called three times in (almost) the same fashion. The only difference is, that the last call contains the new value for the property. I am a bit stumped here. Why three times, and why are my new properties behaving differently? I'd be grateful for any help on that matter! =)

  • Validation - Data Integrity

    - by Thomas
    A table can only store 10 records in a particular state, 10 users over 30 years for example, the others must be less than 30 years. It is a business rule and as such should be respected. How to ensure that state? Think: multiple users accessing this table.

  • SQLite: does data type depend on the quotes?

    - by Septagram
    In SQLite, the datatype of a value is associated with the value itself, not with the column type. So suppose we have a table with an integer primary key "id" and an integer column "some_number". If I do a query like this: INSERT INTO mytable (id, some_number) VALUES (NULL, "1234") Will 123 be inserted as an integer or as string? What consequences it will have later for me, say, when I'm comparing it with other value like "234" (as a number 1234 234, as a string "1234" < "234", right?)?

  • Random begining index iterator for HashSet

    - by funktku
    I use HashSet for add(); remove(); clear(); iterator(); methods. So far everything worked like a charm. However, now I need to fulfill a different requirement. I'd like to be able to start iterating from a certain index. For example, I'd like the following two programs to have same output. Program 1 Iterator it=map.iterator(); for(int i=0;i<100;i++) { it.next(); } while (it.hasNext()) { doSomethingWith(it.next()); } Program 2 Iterator it=map.iterator(100); while (it.hasNext()) { doSomethingWith(it.next()); } The reason I don't want to use the Program 1 is that it creates un-neccesary overhead. From my researchs, I couldn't not find a practical way of creating an iterator with begining index. So, my question is, what would be a good way to achieve my goal while minimizing the overheads? Thank you.

  • Is is faster to filter and get data or filter then get data ?
