• DROP TABLE fails for temp table

  - by StarBright

  I have a client application that creates a temp table, the performs a bulk insert into the temp table, then executes some SQL using the table before deleting it. Pseudo-code: open connection begin transaction CREATE TABLE #Temp ([Id] AS int) bulk insert 500 rows into #Temp UPDATE [OtherTable] SET [Status]=0 WHERE [Id] IN (SELECT [Id] FROM #Temp) AND [Group]=1 DELETE FROM #Temp WHERE [Id] IN (SELECT [Id] FROM [OtherTable] WHERE [Group]=1) INSERT INTO [OtherTable] ([Group], [Id]) SELECT 1 as [Group], [DocIden] FROM #Temp DROP TABLE #Temp COMMIT TRANSACTION CLOSE CONNECTION This is failing with an error on the DROP statement: Cannot drop the table '#Temp', because it does not exist or you do not have permission. I can't imagine how this failure could occur without something else going on first, but I don't see any other failures occurring before this. Is there anything that I'm missing that could be causing this to happen?

• How to transfer SQLite db to web server

  - by Shane

  Hi, I have an application that creates an SQLite database and saves information to it over the course of a day. At the end of the day i want to export this database to a web server. Could anyone point me in the right direction for this? Should I use httppost or put. I have researched this myself online but there seems to be so many different ways to explore. The server side does not exist yet either. I have access to an apache server so i am hoping to use that. Could anyone advise me the best/most simple way to do this? Thanks

• Alternative to DITA Open Toolkit

  - by Adam

  I'm working on a web app that will need to process DITA documents from persistent storage (likely a JCR). The DITA Open Toolkit is the only DITA implementation I'm aware of, but it requires all of your documents to exist on the filesystem. Ideally, I'd like something that works like the DITA OT, but allows you to provide a resolver (much like an XSLT URIResolver) to pull referenced content from other sources. If people have other ideas, such as using a virtual filesystem to trick the DITA OT into working, I'd love to hear those too. Thanks!

• GORM ID generation and belongsTo association ?

  - by fabien-barbier

  I have two domains : class CodeSetDetail { String id String codeSummaryId static hasMany = [codes:CodeSummary] static constraints = { id(unique:true,blank:false) } static mapping = { version false id column:'code_set_detail_id', generator: 'assigned' } } and : class CodeSummary { String id String codeClass String name String accession static belongsTo = [codeSetDetail:CodeSetDetail] static constraints = { id(unique:true,blank:false) } static mapping = { version false id column:'code_summary_id', generator: 'assigned' } } I get two tables with columns: code_set_detail: code_set_detail_id code_summary_id and code_summary: code_summary_id code_set_detail_id (should not exist) code_class name accession I would like to link code_set_detail table and code_summary table by 'code_summary_id' (and not by 'code_set_detail_id'). Note : 'code_summary_id' is define as column in code_set_detail table, and define as primary key in code_summary table. To sum-up, I would like define 'code_summary_id' as primary key in code_summary table, and map 'code_summary_id' in code_set_detail table. How to define a primary key in a table, and also map this key to another table ?

• Rails: ValidationReflection and Formtastic not working together

  - by user336777

  I installed validation_reflection as a gem and out of the box it picked up on my validates_presence_of validations. But it is not picking up on any of the other default rails validations such as validates_format_of. I know from the documentation that i am supposed to add something like: config.reflected_validations << :validates_format_of to my config/plugins/validation_reflection.rb file (which didn't exist initially). I did this but nothing changed (i restarted the web server in between). I am not sure if it just isn't picking up on my file and loading validation_reflection.rb or if i have done something wrong. Anyone have any insights?

• Jetty 6 to Jetty 7 upgrade: what happened to system property "jetty.lib"? (-Djetty.lib=my/lib/dir)

  - by StaxMan

  Looks like Jetty team wanted to do some spring cleaning between versions 6 and 7, and it looks as if one useful system property, "jetty.lib" either does not exist, does not work, or just has changed in an unspecified way so as to make my jetty 6 set up work easily with Jetty 7. I tried searching through Jetty 7 docs, but about the only reference I saw was that "some commonly used properties (such as "jetty.home") still work as they used to". So, what am I missing? I really would want to avoid messing with things within Jetty distribution dirs (otherwise I could -- and maybe I have to? -- just use JETTY_BASE/lib/ext), and that's what "jetty.lib" was useful for.

• basic device that can connect to internet

  - by Hellnar

  Hello, I am looking for a cheap solution to my problem: I need to find either a common device (that is used in restaurants, bars clubs) or a cheap new device that can connect to internet (via the already existing ethernet or wireless based internet) and do HTTP request/receive response and retrieve information ? (For instance can a POS device connect to internet?) For a project, I need to do identity validation on several restaurants and bars and not all of them have computers. So I will be giving "cheap and easy to use devices" and non-IT personal can use it to do http request to my server and get response. All I can think of is Cell phones and SMS.

• Sharepoint Foundation 2010 development environment installation problems

  - by Robert Koritnik

  I'm having problems installing development machine for Sharepoint (Foundation) 2010. This is what I did so far on the same machine: Installed a clean Windows 7 x64 with 4GB of RAM without being part of any domain. Just a simple standalone machine. Enabled IIS related features as described here except IIS6 related ones (two of them) Installed SQL Server 2008 R2 Development Edition (DB Engine and Writer being enabled but not SQL Agent) Installed Visual Studio 2010 Premium Started installing Sharepoint Foundation 2010 with first extracting files, changing config to enable Windows 7 installation and then installed it as Server Farm (then Complete) to avoid installing SQL Express. Created a separate SPF_CONFIG local user with Logon on as a service right. Opened SPF Management Shell and run New-SPConfigurationDatabase so I am able to use a non-domain username (SPF_CONFIG that I created in the previous step) But all I get is this: The outcome after this error is: Database Sharepoint2010Config is created User SPF_CONFIG is added to SQL Server and attached to this newly created database as dbowner Checking SQL server security logins this user has following rights: dbcreator securityadmin public

• Building dictionary of words from large text

  - by LiorH

  I have a text file containing posts in English/Italian. I would like to read the posts into a data matrix so that each row represents a post and each column a word. The cells in the matrix are the counts of how many times each word appears in the post. The dictionary should consist of all the words in the whole file or a non exhaustive English/Italian dictionary. I know this is a common essential preprocessing step for NLP. Does anyone know of a tool\project that can perform this task? Someone mentioned apache lucene, do you know if lucene index can be serialized to a data-structure similar to my needs?

• Exceptions in constructors

  - by FredOverflow

  In C++, the lifetime of an object begins when the constructor finishes successfully. Inside the constructor, the object does not exist yet. Q: What does emitting an exception from a constructor mean? A: It means that construction has failed, the object never existed, its lifetime never began. [source] My question is: Does the same hold true for Java? What happens, for example, if I hand this to another object, and then my constructor fails? Foo() { Bar.remember(this); throw new IllegalStateException(); } Is this well-defined? Does Bar now have a reference to a non-object?

• Strange error in ASP.NET

  - by rockinthesixstring

  Every once in a while I get about 10 - 20 identical errors on my asp.net app. It's always the same, and I'm wondering if it is someone trying to hack in (it happens about once a month).

• Which layer should create DataContext?

  - by Kevin

  I have a problem to decide which layer in my system should create DataContext. I have read a book, saying that if do not pass the same DataContext object for all the database updates, it will sometimes get an exception thrown from the DataContext. That's why i initially create new instance of DataContext in business layer, and pass it into data access layer. So that the same datacontext is used for all the updates. But this lead to one design problem, if i wanna change my DAL to Non-LinqToSQL in future, i need to re-write the code in business layer as well. Please give me some advice on this. Thanks. Example code 'Business Layer Public Sub SaveData(name As String) Using ts AS New TransactionScope() Using db As New MyDataContext() DAL.Insert(db,name) DAL.Insert(db,name) End Using ts.Complete() End Using End Sub 'Data Access Layer Public Sub Insert(db as MyDataContext,name As string) db.TableAInsert(name) End Sub

• XHtml Strict, Float: Center ?

  - by Axel Myers

  Hi everyone. I'm having hard time with Xhtml Strict 1.0 and Css. And I'm almost out of solutions. My Site Url: http://www.pro-turk.net/beta/ I made a jquery multilevel dropdown menu for my site. It looks like OK, but I have used inline-block property of css display attribute on navigation menu which is a part of css 2.1 and isn't supported by some browsers (including ie6 and ie7). I want to make #nav li elements block level elements, but to do this and having all of them in same line, the only way is using float in #nav li. But I want to center them in their parent (the menu bar). So I need something like float:center (I know it's pretty stupid and doesn't exist). But is there a way to include block level elements as children elements without linebreaks (I mean without making a block level element). Regards.

• pyODBC and Unicode Problem

  - by Aviv Giladi

  Hey guys, I'm working with pyODBC communicate with a MS SQL 2005 Express server. The table to which i'm trying to save the data consists of nvarchar columns. query = u"INSERT INTO tblPersons (name, birthday, gender) VALUES('" query = query + name + u"', '" query = query + birthday + u"', '" query = query + gender + u"')" cur.execute(query ) The variables name, birthrday and gende are read from an Excel file and they are Unicode strings. When I execute the query and either look at the table with SQL Server Management Studio or execute a query that fetches the data that was just inserted, all the data that was written in a non-English languages turn into question marks. The data that was written in English is preserved and appears in the table in the correct way. I tried adding CHARSET=UTF16 to my connection string, but had no luck with that. I can use UTF-8 which works fine but as a working convention, I need all the data saved in my DB to be UTF16. Thanks!

• Easy way to Populate a Dictionary<string,List<string>>

  - by zion

  Greetings Guru's, my objective is to create a Dictionary of Lists, does a simpler technique exist? I prefer the List(t) to IEnumerable(t) which is why I chose the Dictionary of Lists over Ilookup or IGrouping. The code works but it seems like a messy way of doing things. string[] files = Directory.GetFiles (@"C:\test"); Dictionary<string,List<string>> DataX = new Dictionary<string,List<string>>(); foreach (var group in files.GroupBy (file => Path.GetExtension (file))) { DataX.Add (group.Key, group.ToList()); }

• How to debug unreleased COM references from managed code?

  - by Marek

  I have been searching for a tool to debug unreleased COM references, that usually cause e.g. Word/Outlook processes to hang in memory in case the code does not call Marshal.ReleaseCOMObject on all COM instances correctly. (Outlook 2007 partially fixes this for outlook addins, but this is a generic question). Is there a tool that would display at least a list of COM references (by type) held by managed code? Ideally, it would also display memory profiler-style object trees helping to debug where the reference increment occured. Debugging at runtime is not that important as being able to attach to a hung process - because the problem typically occurs when the code is done with the COM interface and someone forgot to release something - the application (e.g. winword) hangs in memory even after the calling managed application quits. If such tool does not exist, what is the (technical?) reason? It would be very useful for debugging a lot of otherwise very hard to find problems when working with COM interop.

• Data import wizard library for .Net?

  - by Phil

  Does anyone know of a 3rd party data import wizard that can be embedded into applications? It should import from Excel, Access, SQLServer, csv, tab-separated flat file, XML, Oracle etc. We have a fixed data structure within our application and the user should be able to configure the wizard to match his/her import fields to our own data structure. The wizard should be a library of sorts – preferably a .Net type library. We may want to have it both web-based and desktop based (hence we may need an ASP.Net controls version and a Winforms version). We may also want integration with WPF and Silverlight. If there’s no UI wizard available, does anyone know of a non-UI library that supports easily configurable import from many, many different datasources?

• Python: Why can't I use `super` on a class?

  - by cool-RR

  Why can't I use super to get a method of a class's superclass? Example: Python 3.1.3 >>> class A(object): ... def my_method(self): pass >>> class B(A): ... def my_method(self): pass >>> super(B).my_method Traceback (most recent call last): File "<pyshell#2>", line 1, in <module> super(B).my_method AttributeError: 'super' object has no attribute 'my_method' (Of course this is a trivial case where I could just do A.my_method, but I needed this for a case of diamond-inheritance.) According to super's documentation, it seems like what I want should be possible. This is super's documentation: (Emphasis mine) super() - same as super(__class__, <first argument>) super(type) - unbound super object super(type, obj) - bound super object; requires isinstance(obj, type) super(type, type2) - bound super object; requires issubclass(type2, type) [non-relevant examples redacted]

• Which collection interface should I use in .NET for COM-interop?

  - by jhominal

  That is a followup from my previous question, but you don't need to read it to understand that one. I'm designing an interface in .NET that would be consumed from COM applications (mainly VB6, but Visual C++ 6 is also a possibility) and I would like to use Collection types as argument and return types for the methods in the interface. Questions: What happens to the VB6 built-in collection types (arrays, collections, dictionaries) when they go through interop? My current guess is that: arrays - System.Array collections - Microsoft.VisualBasic.Collection dictionaries - System.Collections.Hashtable Is that correct? Which interfaces should I use as return types? IEnumerable, ICollection, IList, IDictionary? Would I be able to do a For Each in VB6 to iterate over these interfaces? Should I use the generic or non-generic variants of the interfaces?

• Sql Server - INSERT INTO SELECT to avoid duplicates

  - by Ashish Gupta

  I have following two tables:- Table1 ------------- ID Name 1 A 2 B 3 C Table2 -------- ID Name 1 Z I need to insert data from Table1 to Table2 and I can use following sytax for the same:- INSERT INTO Table2(Id, Name) SELECT Id, Name FROM Table1 However, In my case duplicate Ids might exist in Table2 (In my case Its Just "1") and I dont want to copy that again as that would throw an error. I can write something like this:- IF NOT EXISTS(SELECT 1 FROM Table2 WHERE Id=1) INSERT INTO Table2 (Id, name) SELECT Id, name FROM Table1 ELSE INSERT INTO Table2 (Id, name) SELECT Id, name FROM Table1 WHERE Table1.Id<>1 Is there a better way to do this without using IF - ELSE? I want to avoid two INSERT INTO-SELECT statements based on some condition. Any help is appreciated.

• Strange Recurrent Excessive I/O Wait

  - by Chris

  I know quite well that I/O wait has been discussed multiple times on this site, but all the other topics seem to cover constant I/O latency, while the I/O problem we need to solve on our server occurs at irregular (short) intervals, but is ever-present with massive spikes of up to 20k ms a-wait and service times of 2 seconds. The disk affected is /dev/sdb (Seagate Barracuda, for details see below).

Therefore, we did a sync and then this to flush the cache and buffers: echo 3 > /proc/sys/vm/drop_caches and directly afterwards the I/O wait and service times virtually went through the roof, and everything on the machine felt like slow motion. During the next few hours the latency recovered and everything was as before - small to medium lags in short, unpredictable intervals. Now my question is: does anybody have any idea what might cause this annoying behaviour? Is it the first indication of the disk array or the raid controller dying, or something that can be easily mended by rebooting? (At the moment we're very reluctant to do this, however, because we're afraid that the disks might not come back up again.) Any help is greatly appreciated. Thanks in advance, Chris. Edited to add: we do see one or two processes go to 'D' state in top, one of which seems to be kjournald rather frequently. If I'm not mistaken, however, this does not indicate the processes causing the latency, but rather those affected by it - correct me if I'm wrong. Does the information about uninterruptibly sleeping processes help us in any way to address the problem? @Andy Shinn requested smartctl data, here it is: smartctl -a -d megaraid,2 /dev/sdb yields: smartctl 5.40 2010-07-12 r3124 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Device: SEAGATE ST3500620SS Version: MS05 Serial number: Device type: disk Transport protocol: SAS Local Time is: Mon Oct 14 20:37:13 2013 CEST Device supports SMART and is Enabled Temperature Warning Disabled or Not Supported SMART Health Status: OK Current Drive Temperature: 20 C Drive Trip Temperature: 68 C Elements in grown defect list: 0 Vendor (Seagate) cache information Blocks sent to initiator = 1236631092 Blocks received from initiator = 1097862364 Blocks read from cache and sent to initiator = 1383620256 Number of read and write commands whose size <= segment size = 531295338 Number of read and write commands whose size > segment size = 51986460 Vendor (Seagate/Hitachi) factory information number of hours powered up = 36556.93 number of minutes until next internal SMART test = 32 Error counter log: Errors Corrected by Total Correction Gigabytes Total ECC rereads/ errors algorithm processed uncorrected fast | delayed rewrites corrected invocations [10^9 bytes] errors read: 509271032 47 0 509271079 509271079 20981.423 0 write: 0 0 0 0 0 5022.039 0 verify: 1870931090 196 0 1870931286 1870931286 100558.708 0 Non-medium error count: 0 SMART Self-test log Num Test Status segment LifeTime LBA_first_err [SK ASC ASQ] Description number (hours) # 1 Background short Completed 16 36538 - [- - -] # 2 Background short Completed 16 36514 - [- - -] # 3 Background short Completed 16 36490 - [- - -] # 4 Background short Completed 16 36466 - [- - -] # 5 Background short Completed 16 36442 - [- - -] # 6 Background long Completed 16 36420 - [- - -] # 7 Background short Completed 16 36394 - [- - -] # 8 Background short Completed 16 36370 - [- - -] # 9 Background long Completed 16 36364 - [- - -] #10 Background short Completed 16 36361 - [- - -] #11 Background long Completed 16 2 - [- - -] #12 Background short Completed 16 0 - [- - -] Long (extended) Self Test duration: 6798 seconds [113.3 minutes] smartctl -a -d megaraid,3 /dev/sdb yields: smartctl 5.40 2010-07-12 r3124 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Device: SEAGATE ST3500620SS Version: MS05 Serial number: Device type: disk Transport protocol: SAS Local Time is: Mon Oct 14 20:37:26 2013 CEST Device supports SMART and is Enabled Temperature Warning Disabled or Not Supported SMART Health Status: OK Current Drive Temperature: 19 C Drive Trip Temperature: 68 C Elements in grown defect list: 0 Vendor (Seagate) cache information Blocks sent to initiator = 288745640 Blocks received from initiator = 1097848399 Blocks read from cache and sent to initiator = 1304149705 Number of read and write commands whose size <= segment size = 527414694 Number of read and write commands whose size > segment size = 51986460 Vendor (Seagate/Hitachi) factory information number of hours powered up = 36596.83 number of minutes until next internal SMART test = 28 Error counter log: Errors Corrected by Total Correction Gigabytes Total ECC rereads/ errors algorithm processed uncorrected fast | delayed rewrites corrected invocations [10^9 bytes] errors read: 610862490 44 0 610862534 610862534 20470.133 0 write: 0 0 0 0 0 5022.480 0 verify: 2861227413 203 0 2861227616 2861227616 100872.443 0 Non-medium error count: 1 SMART Self-test log Num Test Status segment LifeTime LBA_first_err [SK ASC ASQ] Description number (hours) # 1 Background short Completed 16 36580 - [- - -] # 2 Background short Completed 16 36556 - [- - -] # 3 Background short Completed 16 36532 - [- - -] # 4 Background short Completed 16 36508 - [- - -] # 5 Background short Completed 16 36484 - [- - -] # 6 Background long Completed 16 36462 - [- - -] # 7 Background short Completed 16 36436 - [- - -] # 8 Background short Completed 16 36412 - [- - -] # 9 Background long Completed 16 36404 - [- - -] #10 Background short Completed 16 36401 - [- - -] #11 Background long Completed 16 2 - [- - -] #12 Background short Completed 16 0 - [- - -] Long (extended) Self Test duration: 6798 seconds [113.3 minutes]

• Access to Apache::DBI from DBI

  - by hpavc

  Is it possible to access a Apache::DBI database handle from a perl script (that isn't running under mod_perl). What I am looking for is database pooling for my perl scripts, I have a fair number of database sources (oracle/mysql) and a growing number of scripts. Some ideas like SQLRelay, using Oracle10XE with database links and pooling, and or convert all scripts to SOAP calls, etc are becoming more and more viable. But if there was a mechanism for reusing Apache::DBI I could fight this a bit. I have no non-perl requirements, so we don't have a php/jdbc implementation or similar to deal with. Thanks

• Getting empty result within PHP when in browser I get the JSON exception

  - by Pentium10

  I have this code: $url="https://graph.facebook.com/me/friends?access_token=".$access_token."&fields=id,first_name,last_name&limit=10"; $content=file_get_contents($url); Whenever I use this on a non authenticated user I should get feedback of OAuthException, which doesn't show up in the PHP the $content is empty. While if I copy the URL to the browser I get the result and I see the exception. I want to detect if the user is logged in and the session data is valid. What might be wrong?

• How to make teamcity's svn checkout more verbose?

  - by Benju

  We have a very large svn external containing about 30,000 500k files. This checkout can take a long time and we would like to see the progress in the TeamCity logs as it happens. Is there a way to use a more verbose logging when doing the svn checkout than just.... [19:26:00]: Updating sources: Agent side checkout...

• Regex question: Why isn't this matching?

  - by AllenG

  I have the following regex: (?<=\.\d+?)0+(?=\D|$) I'm running it against a string which contains the following: SVC~NU^0270~313.3~329.18~~10~~6.00: When it runs, it matches the 6.00 (correctly) which my logic then trims by one zero to turn into 6.0. The regex then runs again (or should) but fails to pick up the 6.0. I'm by no means an expert on Regex, but my understanding of my expression is that it's looking for a decimal with 1 or more optional (so, really zero or more) digits prior to one or more zeros which are then followed by any non-digit character or the line break. Assuming that interpretation is correct, I can't see why it wouldn't match on the second pass. For that matter, I'm not sure why my Regex.Replace isn't matching the full 6.00 on the first pass and removing both of the trailing zeros... Any suggestions?
