• How to tell the Session to throw the error query[NHibernate]?

  - by xandy

  I made a test class against the repository methods shown below: public void AddFile<TFileType>(TFileType FileToAdd) where TFileType : File { try { _session.Save(FileToAdd); _session.Flush(); } catch (Exception e) { if (e.InnerException.Message.Contains("Violation of UNIQUE KEY")) throw new ArgumentException("Unique Name must be unique"); else throw e; } } public void RemoveFile(File FileToRemove) { _session.Delete(FileToRemove); _session.Flush(); } And the test class: try { Data.File crashFile = new Data.File(); crashFile.UniqueName = "NonUniqueFileNameTest"; crashFile.Extension = ".abc"; repo.AddFile(crashFile); Assert.Fail(); } catch (Exception e) { Assert.IsInstanceOfType(e, typeof(ArgumentException)); } // Clean up the file Data.File removeFile = repo.GetFiles().Where(f => f.UniqueName == "NonUniqueFileNameTest").FirstOrDefault(); repo.RemoveFile(removeFile); The test fails. When I step in to trace the problem, I found out that when I do the _session.flush() right after _session.delete(), it throws the exception, and if I look at the sql it does, it is actually submitting a "INSERT INTO" statement, which is exactly the sql that cause UNIQUE CONSTRAINT error. I tried to encapsulate both in transaction but still same problem happens. Anyone know the reason?

• MS SQL Server slows down over time?

  - by Dave Holland

  Have any of you experienced the following, and have you found a solution: A large part of our website's back-end is MS SQL Server 2005. Every week or two weeks the site begins running slower - and I see queries taking longer and longer to complete in SQL. I have a query that I like to use: USE master select text,wait_time,blocking_session_id AS "Block", percent_complete, * from sys.dm_exec_requests CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS s2 order by start_time asc Which is fairly useful... it gives a snapshot of everything that's running right at that moment against your SQL server. What's nice is that even if your CPU is pegged at 100% for some reason and Activity Monitor is refusing to load (I'm sure some of you have been there) this query still returns and you can see what query is killing your DB. When I run this, or Activity Monitor during the times that SQL has begun to slow down I don't see any specific queries causing the issue - they are ALL running slower across the board. If I restart the MS SQL Service then everything is fine, it speeds right up - for a week or two until it happens again. Nothing that I can think of has changed, but this just started a few months ago... Ideas? --Added Please note that when this database slowdown happens it doesn't matter if we are getting 100K page views an hour (busier time of day) or 10K page views an hour (slow time) the queries all take a longer time to complete than normal. The server isn't really under stress - the CPU isn't high, the disk usage doesn't seem to be out of control... it feels like index fragmentation or something of the sort but that doesn't seem to be the case. As far as pasting results of the query I pasted above I really can't do that. The Query above lists the login of the user performing the task, the entire query, etc etc.. and I'd really not like to hand out the names of my databases, tables, columns and the logins online :)... I can tell you that the queries running at that time are normal, standard queries for our site that run all the time, nothing out of the norm.

• Hyperic HQ- Monitor process statistics for 50+ processes on Linux machine

  - by Chris

  Is there an easy way to get metrics on all processes that start with the letters XYZ? I have about 80 processes that I have to monitor individually that all start with the prefix XYZ. I have created a query using the sigar shell: ps State.Name.sw=XYZ, which will give me a list of the processes that I want. What I need to do is define this list of processes through said query and collect and track statistics from the Process service: http://support.hyperic.com/display/hypcomm/Process+service What I need is 3 or 4 key statistics for each of the XYZ processes defined by my query to show up as graphs in the web front end. Note: Hyperic HQ server is installed on a windows machine and I'm monitoring a Linux box via an agent. Thanks, Chris Edit: Here is my try at a plugin that may give me what I want, but it's not being inventoried/detected by the Hyperic web UI. Simply pointing me to one of Hyperic's tutorials won't do. Thanks. <!DOCTYPE plugin [ <!ENTITY process-metrics SYSTEM "/pdk/plugins/process-metrics.xml">]> <plugin> <server name="ABCStats"> <config> <option name="process.query" description="Process Query" default="State.Name.sw=XYZ"/> </config> <metric name="Availability" alias="Availability" template="sigar:Type=ProcState,Arg=%process.query%:State" category="AVAILABILITY" indicator="true" units="percentage" collectionType="dynamic"/> &process-metrics; <plugin type="autoinventory"/> <plugin type="measurement" class="org.hyperic.hq.product.MeasurementPlugin"/> </server> </plugin>

• Concatenate cells that change daily automatically?

  - by Harold

  I use concatenate to pull data together from different cells in my spreadsheet. Since my data changes daily, I want the formula to also change daily without having to manually input the new cell in the concatenate formula. I am looking for a way to do this but not sure how. Can anyone out there help me out please!? I appreciate the assistance in advance! Maybe this will help to explain what I need. I have a row of data from D4:AH4 that I insert daily based on the new day. When I use the concatenate and us the following formula: =CONCATENATE(TEXT('Raw Data'!B4,"m/d")," ",TEXT('Raw Data'!C4,"")," ", TEXT('Raw Data'!E4,"0.0%"))... E4 being the cell that changes daily where next day would be F4, G4, etc... All other parts of the formula will stay the same. I hope this helps! Thanks! :)

• Excel 2007 - Adding line breaks in a cell and no line over 50 characters

  - by Richard Drew

  I have notes stored in an excel cell. I add line breaks and dates every time I add a new note. I need to copy this to another program, but it has a line limit of 50 characters. I want a line break for each new date and for when each date's comment goes over 50 characters. I'm able to do one or the other, but I can't figure out how to do both. I'd prefer words not to be split up, but at this point I don't care. Below is some sample input. If needed for a SUBSTITUTE or REPLACE function, I could add a ~ before each date in my input as a delimiter. Sample Input: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates and locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] 05/14 - Copy sent to John Public and [email protected] Ideal Output: 07/03 - FU on query. Copies and history included. CC to Jane Doe and John Public 06/29 - Cust claiming not to have these and wrong PO on query form. Responded with inv sent dates an d locations, correct PO values, and copies. 06/27 - New ticket opened using query form 06/12 - Opened ticket with helpdesk asking status 05/21 - Copy submitted to [email protected] om 05/14 - Copy sent to John Public and email@custome r.com

• Cisco 3560+ipservices -- IGMP snooping issue with TTL=1

  - by Jander

  I've got a C3560 with Enhanced (IPSERVICES) image, routing multicast between its VLANs with no external multicast router. It's serving a test environment where developers may generate multicast traffic on arbitrary addresses. Everything is working fine except when someone sends out multicast traffic with TTL=1, in which case the multicast packet suppression fails and the traffic is broadcast to all members of the VLAN. It looks to me like because the TTL is 1, the multicast routing subsystem doesn't see the packets, so it doesn't create a mroute table entry. If I send out packets with TTL=2 briefly, then switch to TTL=1 packets, they are filtered correctly until the mroute entry expires. My question: is there some trick to getting the switch to filter the TTL=1 packets, or am I out of luck? Below are the relevant parts of the config, with a representative VLAN interface. I can provide more info as needed. #show run ... ip routing ip multicast-routing distributed no ip igmp snooping report-suppression ! interface Vlan44 ip address 172.23.44.1 255.255.255.0 no ip proxy-arp ip pim passive ... #show ip igmp snooping vlan 44 Global IGMP Snooping configuration: ------------------------------------------- IGMP snooping : Enabled IGMPv3 snooping (minimal) : Enabled Report suppression : Disabled TCN solicit query : Disabled TCN flood query count : 2 Robustness variable : 2 Last member query count : 2 Last member query interval : 1000 Vlan 44: -------- IGMP snooping : Enabled IGMPv2 immediate leave : Disabled Multicast router learning mode : pim-dvmrp CGMP interoperability mode : IGMP_ONLY Robustness variable : 2 Last member query count : 2 Last member query interval : 1000

• Is there a more elegant way to apply conditions in nginx?

  - by Ryan Detzel

  Is there a better way to do this? I can't find a way to nest or apply boolean operators to conditions in nginx. Basically if there is a cookie set(non-anonymous user) we want to hit the server. If the cookie is not set and the file exists we want to server the file otherwise hit the server. set $test "D"; if ($http_cookie ~* "session" ) { set $test "${test}C"; } if (-f $request_filename/index.html$is_args$args) { set $test "${test}F"; } if ($test = DF){ rewrite (.*)/ $1/index.html$is_args$args? break; } if ($test = DCF){ proxy_pass http://django; break; } if ($test = DC){ proxy_pass http://django; break; } if ($test = D){ proxy_pass http://django; break; }

• BadPaddingException in Android encrypt

  - by DarthRoman

  Hi everyone, I am making an Android application, and I want to encrypt a String before sending it to a DataBase, and encrytpion is correct. The problem is when I am going to decrypt the String, because I get a BadPaddingException and I have no idea where the problem is. Here is the code: public final static String HEX = "36A52C8FB7DF9A3F"; public static String encrypt(String seed, String cleartext) throws Exception { byte[] rawKey = getRawKey(seed.getBytes()); byte[] result = encrypt(rawKey, cleartext.getBytes()); return toHex(result); } public static String decrypt(String seed, String encrypted) throws Exception { byte[] rawKey = getRawKey(seed.getBytes()); byte[] enc = toByte(encrypted); byte[] result = decrypt(rawKey, enc); return new String(result); } public static String toHex(String txt) { return toHex(txt.getBytes()); } public static String fromHex(String hex) { return new String(toByte(hex)); } public static byte[] toByte(String hexString) { int len = hexString.length()/2; byte[] result = new byte[len]; for (int i = 0; i < len; i++) result[i] = Integer.valueOf(hexString.substring(2*i, 2*i+2), 16).byteValue(); return result; } public static String toHex(byte[] buf) { if (buf == null) return ""; StringBuffer result = new StringBuffer(2*buf.length); for (int i = 0; i < buf.length; i++) { appendHex(result, buf[i]); } return result.toString(); } private static byte[] getRawKey(byte[] seed) throws Exception { KeyGenerator kgen = KeyGenerator.getInstance("AES"); SecureRandom sr = SecureRandom.getInstance("SHA1PRNG"); sr.setSeed(seed); kgen.init(128, sr); // 192 and 256 bits may not be available SecretKey skey = kgen.generateKey(); byte[] raw = skey.getEncoded(); return raw; } private static byte[] encrypt(byte[] raw, byte[] clear) throws Exception { SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES"); Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.ENCRYPT_MODE, skeySpec); byte[] encrypted = cipher.doFinal(clear); return encrypted; } private static byte[] decrypt(byte[] raw, byte[] encrypted) throws Exception { SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES"); Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.DECRYPT_MODE, skeySpec); byte[] decrypted = cipher.doFinal(encrypted); return decrypted; } private static void appendHex(StringBuffer sb, byte b) { sb.append(HEX.charAt((b>>4)&0x0f)).append(HEX.charAt(b&0x0f)); } I encrypt and decrypt with this code: String encrypted = encrypt(HEX, "some text"); String decrypted = decrypt(HEX, encrypted); Can anyone help me please?

• Chrome "refusing to execute script"

  - by TestSubject528491

  In the head of my HTML page, I have: <script src="https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js"></script> When I load the page in my browser (Google Chrome v 27.0.1453.116) and enable the developer tools, it says Refused to execute script from 'https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled. Indeed, the script won't run. Why does Chrome think this is a plaintext file? It clearly has a js file extension. Since I'm using HTML5, I omitted the type attribute, so I thought that might be causing the problem. So I added type="text/javascript" to the <script> tag, and got the same result. I even tried type="application/javascript" and still, same error. Then I tried changing it to type="text/plain" just out of curiosity. The browser did not return an error, but of course the JavaScript did not run. Finally I thought the periods in the filename might be throwing the browser off. So in my HTML, I changed all the periods to the URL escape character %2E: <script src="https://raw.github.com/cloudhead/less%2Ejs/master/dist/less-1%2E3%2E3.js"></script> This still did not work. The only thing that truly works (i.e. the browser does not give an error and the JS successfully runs) is if I download the file, upload it to a local directory, and then change the src value to the local file. I'd rather not do this since I'm trying to save space on my own website. How do I get the Chrome to recognize that the linked file is actually a javascript type?

• Does Hauppauge WinTV HVR-900 (r2) [USB ID 2040:6502] work with ubuntu 12.04 LTS?

  - by nightfly

  I have this DVB+Analog usb tv tuner Hauppauge WinTV HVR-900 (r2) [USB ID 2040:6502]. This used to work under ubuntu 10.04 LTS. But in 12.04 there seems to be a problem.

• How to implement child-parent aggregation link in C++?

  - by Giorgio

  Suppose that I have three classes P, C1, C2, composition (strong aggregation) relations between P <>- C1 and P <>- C2, i.e. every instance of P contains an instance of C1 and an instance of C2, which are destroyed when the parent P instance is destroyed. an association relation between instances of C1 and C2 (not necessarily between children of the same P). To implement this, in C++ I normally define three classes P, C1, C2, define two member variables of P of type boost::shared_ptr<C1>, boost::shared_ptr<C2>, and initialize them with newly created objects in P's constructor, implement the relation between C1 and C2 using a boost::weak_ptr<C2> member variable in C1 and a boost::weak_ptr<C1> member variable in C2 that can be set later via appropriate methods, when the relation is established. Now, I also would like to have a link from each C1 and C2 object to its P parent object. What is a good way to implement this? My current idea is to use a simple constant raw pointer (P * const) that is set from the constructor of P (which, in turn, calls the constructors of C1 and C2), i.e. something like: class C1 { public: C1(P * const p, ...) : paren(p) { ... } private: P * const parent; ... }; class P { public: P(...) : childC1(new C1(this, ...)) ... { ... } private: boost::shared_ptr<C1> childC1; ... }; Honestly I see no risk in using a private constant raw pointer in this way but I know that raw pointers are often frowned upon in C++ so I was wondering if there is an alternative solution.

• Chrome refused to execute this JavaScript file

  - by TestSubject528491

  In the head of my HTML page, I have: <script src="https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js"></script> When I load the page in my browser (Google Chrome v 27.0.1453.116) and enable the developer tools, it says: Refused to execute script from 'https://raw.github.com/cloudhead/less.js/master/dist/less-1.3.3.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled. Indeed, the script won't run. Why does Chrome think this is a plain text file? It clearly has a .js file extension. Since I'm using HTML5, I omitted the type attribute, so I thought that might be causing the problem. So I added type="text/javascript" to the <script> tag, and got the same result. I even tried type="application/javascript" and still got the same error. Then I tried changing it to type="text/plain" just out of curiosity. The browser did not return an error, but of course the JavaScript did not run either. Finally I thought the periods in the filename might be throwing the browser off. So in my HTML code, I changed all the periods to the URL escape character %2E: <script src="https://raw.github.com/cloudhead/less%2Ejs/master/dist/less-1%2E3%2E3.js"></script> This still did not work. The only thing that truly works (i.e. the browser does not give an error and the JS successfully runs) is if I download the file, upload it to a local directory, and then change the src value to the local file. I'd rather not do this since I'm trying to save space on my own website. How do I get Chrome to recognize that the linked file is actually a JavaScript type?

• Java and C# in web development [on hold]

  - by azalut

  I am wondering whether C# development(ASP.NET) is rather kind of "rapid development" or something "big" like JavaEE/Spring? We all know, that RoR or Django are really rapid-development frameworks - and so - is C# closer to Java "long-timed-development" or to frameworks like the two above - Django, RoR? I am, for now, an amateur Java programmer and sometimes I get annoyed with the amount of code that have to be written to create even a short CRUD app. We need a lot of skills to create at least a small app. I want some change, at least for some time and learn something new. I tried (just few hours) first: RoR, then Django and now I am writing in C#. It seems to be like Java but a little bit extended. In respect of future work as a professional coder - Is it profitable to know both competitive technologies like Java (and its frameworks) and C# with .NET(ASP.NET for example)? Maybe better choice is Python? Or just stop being stupid and still work with Java but with another framework(and master my Java skills) or JavaScript, jQuery to be better at web-development? Actually this question depends on your own opinions that is why I know that this question could be blocked by admins. But main question is in the top of the post I mean: is C# web-development rapid or closer to Java? I am afraid, that if I don't try, I will regret in the future, when I awake and think: oh my god, how could I not get familiar with (another_technology_or_language) Thanks for your attention :) ps I had asked the same question on stackoverflow, but it was hold because of being opinion based. Hope it fits here ;)

• MySQL Execution Time Spikes

  - by Brett

  I am having issues with MySQL all of the sudden today. Details: OS: CentOS release 5.7 Server type: Parallels virtuozzo container running on mediatemple DV 4.0 package Average total memory usage: <500mb Total memory usage allowed: 1gb (part of shared pool for emergency only, users are only guaranteed 500mb) Processor: 1ghz Main database sizes with most usage: 275mb & 107mb server stack: nginx 1.0.10, mysql 5.1.54, php 5.3.8 with php-fpm innodb_buffer_pool_size=100M php-fpm max children: 5 Webapps: custom php-based sites, magento & drupal slow query timeout is set to 1 second Steps I completed towards diagnosis: Cannot restart container yet - I will try later tonight when our domestic traffic has dropped Enabled mysql and php-fpm slowlog. Found functions that did DB queries in php-fpm slowlog were taking over 1s to complete at times Found some simple queries in mysql slowlog taking well over 1s to complete that should take less than 1s. Most interesting - execution time seems to spike at times. A query will take .2s a couple times, then one time it will take 8s to run the same query. These results were verified by running raw SQL queries through mysql command line. Top does not reveal anything too interesting Only resource related thing i can see is load averages much higher than normal Up until today, mysql has been fine, there have been no major changes to the db since yesterday. Sometimes things are so bad, I am seeing bad gateway errors after 60s of execution time. Innodb is doing on average 300-1400 reads/sec. Mysql is doing 3-10 queries/sec slow query count in 2 hours uptime is 171 (with slow timeout at 1 second) Tried restarting mysql, nginx, php-fpm multiple times For example: UPDATE `catalogsearch_query` SET `query_text` = 'EW 90', `num_results` = '7532', `popularity` = '99180', `redirect` = NULL, `synonym_for` = NULL, `store_id` = '1', `display_in_terms` = '1', `is_active` = '1', `is_processed` = '1', `updated_at` = '2012-05-08 21:38:31' WHERE (query_id='31'); This query took 17sec to complete one time, rest of the time around .079 sec. But varies, sometimes 1sec, sometimes .004 sec. This is running the same query, over and over with a couple seconds time in between each. Most tables are innodb, and sometimes I noticed the lock time taking 90% of the query execution time, but most of the time lock time is insignificant. Any idea what's going on here?

• VBA + Polymorphism: Override worksheet functions from 3rd party

  - by phi

  my company makes extensive use of a data provider using a (closed source) VBA plugin. In principal, every query follows follows a certain structure: Fill one cell with a formula, where arguments to the formula specify the query the range of that formula is extended (not an arrray formula!) and cells below/right are filled with data For this to work, however, a user has to have a terminal program installed on the machine, as well as a com-plugin referenced in VBA/Excel. My Problem These Excelsheets are used and extended by multiple users, and not all of them have access to the data provider. While they can open the sheet, it will recalculate and the data will be gone. However, frequent recalculation is required. I would like every user to be able to use the sheets, without executing a very specific set of formulas. Attempts remove the reference on those computers where I do not have terminal access. This generates a NAME error i the cell containing the query (acceptable), but this query overrides parts of the data (not acceptable) If you allow the program to refresh, all data will be gone after a failed query Replace all formulas with the plain-text result in the respective cells (press a button and loop over every cell...). Obviously destroys any refresh-capabilities the querys offer for all subsequent users, so pretty bad, too. A theoretical idea, and I'm not sure how to implement it: Replace the functions offered by the plugin with something that will be called either first (and relay the query through to the original function, if thats available) or instead of the original function (by only deploying the solution on non-terminal machines), which just returns the original value. More specifically, if my query function is used like this: =GETALLDATA(Startdate, Enddate, Stockticker, etc) I would like to transparently swap the function behind the call. Do you see any hope, or am I lost? I appreciate your help. PS: Of course I'm talking about Bloomberg... Some additional points to clarify issues raise by Frank: The formula in the sheets may not be changed. This is mission-critical software, and its way too complex for any sane person to try and touch it. Only excel and VBA may be used (which is the reason for the previous point...) It would be sufficient to prevent execution of these few specific formulas/functions on a specific machine for all excel sheets to come This looks more and more like a problem for stackoverflow ;-)

• Can Nokogiri Parse a Nokogiri Object?

  - by Jesse J

  I'm trying to parse a part of the result of a parse, like this: queries = @doc.xpath("//spectrum_query") queries.each do |query| hits = query.xpath("//search_hit") end But instead of Nokogiri only searching for search_hits inside the query, it searches for search_hits in the whole document. I'm sure there's a different way to accomplish what I want, but doing it like this would be the simplest. Anyone know if it's possible to search just the query object?

  Hi I have the following SQL query: select c.id from (select id from customers) c This query has no practical value - I simplified it greatly for the purpose of this post. My question: is it possible have a subquery in the from clause using HQL. If not, can I perhaps query the customers first, kinda like a temp table in sql, and then use the result as the source of the next query? thanks

  - by Ke

  Hi, I'm new to JPA. In SQL, there is "*" which means any all. For example, SELECT * FROM PRODUCT WHERE CATEGORY=* In JPA, the query is: Query query = entityManager.createQuery("select o from Product o WHERE o.category = :value"); query.setParameter("category", category); How can I set category to any category in JPA?

  Hi, I'm new to JPA. In JPA, the query is: Query query = entityManager.createQuery("select o from Product o WHERE o.category = :value"); query.setParameter("category", category); How can I set category to any category in JPA? So if the null category passed, I simple ignore the category parameter, select all products.

  Trying to access google spreadsheets using their api. following their example, the code doesnt work, and its not obvious why. All I'm trying to do is to connect, and I keep getting back the same error. This is with their code set as of 4/15/10. Can anyone offer any suggestion on what I'm doing wrong? CodE: using System; using Google.GData.Client; using Google.GData.Extensions; using Google.GData.Spreadsheets; namespace google_spreadsheet { class Program { static void Main(string[] args) { SpreadsheetsService myService = new SpreadsheetsService("MySpreadsheet" ); myService.setUserCredentials("[email protected]", "xxxxxxx"); string token1 = myService.QueryClientLoginToken(); Console.WriteLine("token is {0}", token1); Console.ReadLine(); SpreadsheetQuery query = new SpreadsheetQuery(); SpreadsheetFeed feed = myService.Query(query); Console.WriteLine("list"); foreach (SpreadsheetEntry entry in feed.Entries) { Console.WriteLine("Value: {0}", entry.Title.Text); When I run this, it keeps erroring out at the myService.Query statement, with the following error: Google.GData.Client.GDataRequestException was unhandled Message=Execution of request failed: http://spreadsheets.google.com/feeds/spreadsheets/private/full Source=Google.GData.Client ResponseString=<HTML> <HEAD> <TITLE>Not Found</TITLE> </HEAD> <BODY BGCOLOR="#FFFFFF" TEXT="#000000"> <H1>Not Found</H1> <H2>Error 404</H2> </BODY> </HTML> StackTrace: at Google.GData.Client.GDataRequest.Execute() at Google.GData.Client.GDataGAuthRequest.Execute(Int32 retryCounter) at Google.GData.Client.GDataGAuthRequest.Execute() at Google.GData.Client.Service.Query(Uri queryUri, DateTime ifModifiedSince, String etag, Int64& contentLength) at Google.GData.Client.Service.Query(Uri queryUri, DateTime ifModifiedSince) at Google.GData.Client.Service.Query(FeedQuery feedQuery) at Google.GData.Spreadsheets.SpreadsheetsService.Query(SpreadsheetQuery feedQuery) at google_spreadsheet.Program.Main(String[] args) in C:\Development Items\VS Projects\VS2008\google_spreadsheet\google_spreadsheet\Program.cs:line 21 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException: System.Net.WebException Message=The remote server returned an error: (404) Not Found.

  - by manu1001

  I'm running this query: SELECT FROM com.Data WHERE entryDate DATE('2010-3-16') I get this error: org.datanucleus.store.appengine.query.DatastoreQuery$UnsupportedDatastoreFeatureException: Problem with query DATE('2010-3-16'): Unsupported method while parsing expression: InvokeExpression{[null].DATE(Literal{2010-3-16})} The same query works when I use it on the admin console. But it does not work for code (java), either locally or when deployed. Any ideas?

• How triggers behave wrt concurrent visibility of transactions?

  - by stach

  I'm working on PostgreSQL 8.4 in read committed mode. I know that for each query, the server makes a snapshot of db state so that the query behaves consistently. Does it include triggers that are called in response to this query? Or is there a new snapshot created for each query called from within a trigger?
