  • Soft delete an entity in Grails with Hibernate Filters Plugin

    - by canotto90
    I was looking for a way to avoid deleting my users from DB, but instead to mark them as deleted and don't bring them back in queries. I found this plugin http://grails.org/plugin/hibernate-filter, which was a great tool for the task. But when I tried to implement my solution, I passed trought same problems whose solutions wheren't (or I was not able to find) on internet. So, next, I describe the way that I solve the problem of soft delete.

  • Select and delete selected

    - by Donator
    I am programming something like e-mail for my users. I want to allow people to select letters and delete selected. How can I do it? I can't imagine how can I do it only with one MySQL query. Is it even possible?

  • Delete System Files containing string

    - by Fuzz Evans
    I am trying to write a batch file that will examine a given directory, read each file for a given string "Example" and then delete any files that contain the string. The files are also System Files so I don't know what the exact extension is or if that matters (maybe you can just omit a file type filter and have it read all files?). Some of the files will be locked from reading as well so it needs to handle access denial errors if that occurs, not sure how batch files handle that.

  • Delete duplicate rows, do not preserve one row

    - by Radley
    I need a query that goes through each entry in a database, checks if a single value is duplicated elsewhere in the database, and if it is - deletes both entries (or all, if more than two). Problem is the entries are URLs, up to 255 characters, with no way of identifying the row. Some existing answers on Stackoverflow do not work for me due to performance limitations, or they use uniqueid which obviously won't work when dealing with a string. Long Version: I have two databases containing URLs (and only URLs). One database has around 3,000 urls and the other around 1,000. However, a large majority of the 1,000 urls were taken from the 3,000 url database. I need to merge the 1,000 into the 3,000 as new entries only. For this, I made a third database with combined URLs from both tables, about 4,000 entries. I need to find all duplicate entries in this database and delete them (Both of them, without leaving either). I have followed the query of a few examples on this site, but whenever I try to delete both entries it ends up deleting all the entries, or giving sql errors. Alternatively: I have two databases, each containing the separate database. I need to check each row from one database against the other to find any that aren't duplicates, and then add those to a third database. Edit: I've got my own PHP solution which is pretty hacky, but works. I cannot answer my own question for 8 hours because I'm new, so here it is for now: I went with a PHP script to accomplish this, as I'm more familiar with PHP than MySQL. This generates a simple list of urls that only exist in the target database, but not both. If you have more than 7,000 entries to parse this may take awhile, and you will need to copy/paste the results into a text file or expand the script to store them back into a database. I'm just doing it manually to save time. Note: Uses MeekroDB <pre> <?php require('meekrodb.2.1.class.php'); DB::$user = 'root'; DB::$password = ''; DB::$dbName = 'testdb'; $all = DB::query('SELECT * FROM old_urls LIMIT 7000'); foreach($all as $row) { $test = DB::query('SELECT url FROM new_urls WHERE url=%s', $row['url']); if (!is_array($test)) { echo $row['url'] . "\n"; }else{ if (count($test) == 0) { echo $row['url'] . "\n"; } } } ?> </pre>

  • How do I delete old calendar items in Outlook 2003?

    - by Ramesh
    Hi. I'm trying to delete old calendar items (I have a few years' worth) in Outlook and was wondering if there was a way to delete only non-recurring items as I need the recurring events for the future. I tried View Arrange by Current view Category and figured that I could manually check and delete any calendar items by hand. Is there a more efficient way to do this without having to actually script code? Thanks for your time!

  • Windows XP: How to delete files and folders that cannot be deleted?

    - by glenneroo
    I have a backup copy of a previous Windows' Documents and Settings folder which only contains my original user and within 2 more directories: Favorites and Local Settings. When I try to delete Local Settings I get this error: When I try to delete Favorites, I get this error: I ran this in a cmd shell: attrib *.* -r -a -s -h /s ...but it did not help, nor did it return any errors/warnings. I used Unlocker v1.8.5 and LockHunter repeatedly at multiple levels to see if any files are in use, but both always say: No Files Locked. Update #1: I was able to rename the directory, which now gives me this warning before (trying to) delete: If I press Yes (or Yes to All) then I get this error: Update #2: I let chkdsk /f run which required a reboot since it's on my primary system partition. During Stage 2 scanning, I received about 40 of these: Deleting an index entry from index $0 of file 25. ...followed by: Deleting index entry cookies in index $I30 of file 37576. ...but I still get the first error dialog above when trying to delete. Update #3: Digging deeper, the 99 is the name of one of many directories located deep in here: C:\Documents and Settings.OLD\User\Local Settings\Application Data\Microsoft\Messenger\[email protected]\SharingMetadata\[email protected]\DFSR\Staging\CS{D4E4AE55-B5E2-F03B-5189-6C4DA6E41788}\ Inside each of those directories were files with names such as: 2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-{C93D01AC-0739-4FD9-88C7-13D2F21A208E}-v2300-Downloaded.frx I noticed that, unlike all the directories, I couldn't rename any of these files. I also noticed that the file + dir names were extremely long: Original directory = 194 characters Filenames = 100+ characters Together the length exceeds the 255-char limit which is bad and would explain the error message I posted in Update #1. Partial Solution: Rename all directories until the total path length is less than 100. Afterwards I was able to rename the .frx files, not to mention delete everything inside the Local Settings directory. This is only a partial solution because this (empty) directory is still undeleteable: C:\1\2\Favorites\Wien\What To Do.. I'm guessing because of the ".." at the end, Windows (Explorer and cmd) can't deal with it: Here is what Explorer properties shows: Any ideas?

C:\1\2\Favorites\Photography\FIRE Same error as above: Here is what Explorer properties shows for both folders: Update #4 (another partial solution): Using harrymc's answer combined with thoroughly reading through this amazing MS-KB article which contains nearly everyone's idea and then some, inconspicuously titled: You cannot delete a file or a folder on an NTFS file system volume. I was able to delete the 2nd folder C:\1\2\Favorites\Photography\FIRE - the problem being that there was an invisible trailing space at the end. I got lucky when I did an auto-complete whilst playing around with the del "\\?\<path>" command which he suggested. NOTE: A normal del did NOT work, nor did deleting from explorer. Now all that is left is the first directory C:\1\2\Favorites\Wien\What To Do.. (yes I tried endlessly with multiple combinations of the above solution ;) Keep 'em coming! =)

  • Why is it not possible to delete IE addons from the IE interface?

    - by axk
    You can disable but you can't delete them from the "Manage addons" dialog. In IE 7 there was a delete button but I've never seen it enabled, in IE 8 I don't see the button at all. My guess would be that IE addons are registered as COM components and you cannot track who uses that component besides IE itself so it would be unsafe to delete.
