  • SubSonic 3.0 Simple Repository Adding a DateTime Property To An Object

    - by Blounty
    I am trying out SubSonic to see if it is viable to use on production projects. I seem to have stumbled upon an issue whith regards to updating the database with default values (String and DateTime) when a new column is created. If a new property of DateTime or String is added to an object. public class Bug { public int BugId { get; set; } public string Title { get; set; } public string Overview { get; set; } public DateTime TrackedDate { get; set; } public DateTime RemovedDate { get; set; } } When the code to add that type of object to the database is run var repository = new SimpleRepository(SimpleRepositoryOptions.RunMigrations); repository.Add(new Bug() { Title = "A Bug", Overview = "An Overview", TrackedDate = DateTime.Now }); it creates the following sql: UPDATE Bugs SET RemovedDate=''01/01/1900 00:00:00'' For some reason it is adding double 2 single quotes to each end of the string or DateTime. This is causing the following error: System.Data.SqlClient.SqlException - Incorrect syntax near '01' I am connecting to SQL Server 2005 Any help would be appreicated as apart from this issue i am finding SubSonic to be a great product. I have created a screen cast of my error here:

  • Bash and regex problem : check for tokens entered into a Coke vending machine

    - by Michael Mao
    Hi all: Here is a "challenge question" I've got from Linux system programming lecture. Any of the following strings will give you a Coke if you kick: L = { aaaa, aab, aba, baa, bb, aaaa"a", aaaa"b", aab"a", … ab"b"a, ba"b"a, ab"bbbbbb"a, ... } The letters shown in wrapped double quotes indicate coins that would have fallen through (but those strings are still part of the language in this example). Exercise (a bit hard) show this is the language of a regular expression And this is what I've got so far : #!/usr/bin/bash echo "A bottle of Coke costs you 40 cents" echo -e "Please enter tokens (a = 10 cents, b = 20 cents) in a sequence like 'abba' :\c" read tokens #if [ $tokens = aaaa ]||[ $tokens = aab ]||[ $tokens = bb ] #then # echo "Good! now a coke is yours!" #else echo "Thanks for your money, byebye!" if [[ $token =~ 'aaaa|aab|bb' ]] then echo "Good! now a coke is yours!" else echo "Thanks for your money, byebye!" fi Sadly it doesn't work... always outputs "Thanks for your money, byebye!" I believe something is wrong with syntax... We didn't provided with any good reference book and the only instruction from the professor was to consult "anything you find useful online" and "research the problem yourself" :( I know how could I do it in any programming language such as Java, but get it done with bash script + regex seems not "a bit hard" but in fact "too hard" for anyone with little knowledge on something advanced as "lookahead"(is this the terminology ?) I don't know if there is a way to express the following concept in the language of regex: Valid entry would consist of exactly one of the three components : aaaa, aab and bb, regardless of order, followed by an arbitrary sequence of a or b's So this is what is should be like : (a{4}Ua{2}bUb{2})(aUb)* where the content in first braces is order irrelevant. Thanks a lot in advance for any hints and/or tips :)

  • Is Software Engineering Dead? [closed]

    - by nik
    Right from Jeff's blog: Software Engineering: Dead? I was utterly floored when I read this new IEEE article by Tom DeMarco (pdf). See if you can tell why. He quotes DeMarco, "I'm gradually coming to the conclusion that software engineering is an idea whose time has come and gone". Further, "What DeMarco seems to be saying -- and, at least, what I am definitely saying -- is that control is ultimately illusory on software development projects." I am writing these lines without context to invoke reading of the related subject. What are the views of the programming community here? I have started to realize that a community wiki is not getting the right amount of participation here. That is the reason I left this question out in the open, while still contemplating a change to CW. It was closed once, and I thought that was the end of it. But, now I see it was reopened and has more answers (all of which I have not yet read). However, I see a lot of CW requests and am forced to reconsider that. This is how I intend to make the CW decision here. There is a comment by Neil Butterworth requesting a CW at 12 upvotes -- "should be community wiki" There is a comment by Lance Roberts requesting no CW at 0 upvotes -- "+1 for not putting it in community wiki" The difference is 12 for a CW request at the moment If this difference becomes 5 more (that is 17), I'll move this question to CW, and it will not return back from there Of course, there is also a close vote at the moment; the question may be closed again.

  • How can I stop SQL Server Management Studio replacing 'SELECT *' with the column list ?

    - by Ben McIntyre
    SQL Server Mgmt Studio is driving me crazy. If I create a view and SELECT '*' from a table, it's all OK and I can save the view. Looking at the SQL for the view (eg.by scripting a CREATE) reveals that the 'SELECT *' really is saved to the view's SQL. But as soon as I reopen the view using the GUI (right click modify), SELECT * is replaced with a column list of all the columns in the table. How can I stop Management Studio from doing this ? I want my 'SELECT *' to remain just that. Perhaps it's just the difficulty of googling 'SELECT *' that prevented me from finding anything remotely relevant to this (i did put it in double quotes). Please, I am highly experienced in Transact-SQL, so please DON'T give me a lecture on why I shouldn't be using SELECT *. I know all the pros and cons and I do use it at times. It's a language feature, and like all language features can be used for good or evil (I emphatically do NOT agree that it is never appropriate to use it). Edit: I'm giving Marc the answer, since it seems it is not possible to turn this behaviour off. Problem is considered closed. I note that Enterprise Manager did no similar thing. The workaround is to either edit SQL as text, or go to a product other than Managment Studio. Or constantly edit out the column list and replace the * every time you edit a view. Sigh.

  • PHP Json Encoding w/ quote escaping in 5.2?

    - by NickAldwin
    I'm playing with the flickr api and php. I want to pass some information from PHP to Javascript through Ajax. I have the following code: json_encode($pics); which results in the following example JSON string: [{"id":"4363603591","title":"blue, white and red...another seattle view","date_faved":"1266379499"},{"id":"4004908219","title":"\u201cI just told you my dreams and you made me see that I could walk into the sun and I could still be me and now I can't deny nothing lasts forever.\u201d","date_faved":"1259987670"}] Javascript has problems with this, however, due to the unescaped single-quote in the second item ("can't deny"). I want to use the function json_encode with the options parameter to make it strip the quotes, but that's only available in PHP 5.3, and I'm running 5.2 (not my server). Is there a fast way to run through the entire array and escape everything before encoding it in Json? I looked for a way to do this, but it all seems to deal with encoding it as the data is generated, something I cannot do as I'm not the one generating the data. If it helps, I'm currently using the following javascript after the ajax request: var photos = eval('(' + resptxt + ')');

  • Binding a date string parameter in an MS Access PDO query

    - by harryg
    I've made a PDO database class which I use to run queries on an MS Access database. When querying using a date condition, as is common in SQL, dates are passed as a string. Access usually expects the date to be surrounded in hashes however. E.g. SELECT transactions.amount FROM transactions WHERE transactions.date = #2013-05-25#; If I where to run this query using PDO I might do the following. //instatiate pdo connection etc... resulting in a $db object $stmt = $db->prepare('SELECT transactions.amount FROM transactions WHERE transactions.date = #:mydate#;'); //prepare the query $stmt->bindValue('mydate', '2013-05-25', PDO::PARAM_STR); //bind the date as a string $stmt->execute(); //run it $result = $stmt->fetch(); //get the results As far as my understanding goes the statement that results from the above would look like this as binding a string results in it being surrounded by quotes: SELECT transactions.amount FROM transactions WHERE transactions.date = #'2013-05-25'#; This causes an error and prevents the statement from running. What's the best way to bind a date string in PDO without causing this error? I'm currently resorting to sprintf-ing the string which I'm sure is bad practise. Edit: if I pass the hash-surrounded date then I still get the error as below: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22018]: Invalid character value for cast specification: -3030 [Microsoft][ODBC Microsoft Access Driver] Data type mismatch in criteria expression.

  • Does posting data with a textarea automatically add slashes to (escape) the text?

    - by animuson
    Ok, so I'm having a problem with a simple textarea. I'm using a kind of hidden page to easily encode some data using JSON. However, all of my text input is automatically being escaped somewhere and I don't know where. All of my $_POST variables are automatically run through the htmlentities() function when the script starts up, as seen below: $ani->i->post = $this->clean($_POST, true); function clean($values, $unset = false) { if (is_array($values)) { foreach ($values as $key => $value) { $newkey = strtolower($key); $return[$newkey] = $this->clean($value); unset($values[$key]); } return $return; } return htmlentities($values); } I keep getting \' for all of my single quotes when I put the value back into the textarea. I can't find anywhere where it would be adding slashes and I don't remember it being a feature that they were automatically added when you submit from a textarea, and if that was so, why would they not be returning back to a single quote when put back into the textarea? Do I really need to run variables through stripslashes() to get them back to their original form? Edit: My 'test.php' file is as follows: <h1>To Be Encoded:</h1> <form action="/test" method="post"> <textarea name="encode" rows="20" cols="50"><?= html_entity_decode($ani->i->post['encode']) ?></textarea> <input type="submit" name="submit" value="Encode It!" /> </form> <h1>Encoded By JSON:</h1> <textarea name="encoded" rows="20" cols="50"><?= json_encode(html_entity_decode($ani->i->post['encode'])) ?></textarea> <?php die(); ?> P.S. The die() is just there for compatibility with my framework.

  • 404 Not Found When Requesting URI With Encoded Patameters

    - by Richard Knop
    I am pretty sure this is some problem with the Apache configuration because it used to work on the previous hosting provider with the same PHP/MySQL configuration. In my application, users are able to delete photos by going to URIs like this: http://example.com/my-account/remove-media/id/9/ret/my-account%252Fedit-album%252Fid%252F1 The paramater id is an id of a photo to be removed, the parameter ret is a relative URL where user should be redirected after the removal of the photo but after clicking on a link like that I get 404 Not Found error with the text: Not Found The requested URL /public/my-account/remove-media/id/9/ret/my-account/edit-album/id/1 was not found on this server. Though it used to work on my previous hosting provider so I guess it is just some easy Apache configuration issue? One more thing, there is a htaccess file that changes the document root to /public: RewriteEngine On php_value upload_max_filesize 15M php_value post_max_size 15M php_value max_execution_time 200 php_value max_input_time 200 # Exclude some directories from URI rewriting #RewriteRule ^(dir1|dir2|dir3) - [L] RewriteRule ^\.htaccess$ - [F] RewriteCond %{REQUEST_URI} ="" RewriteRule ^.*$ /public/index.php [NC,L] RewriteCond %{REQUEST_URI} !^/public/.*$ RewriteRule ^(.*)$ /public/$1 RewriteCond %{REQUEST_FILENAME} -f RewriteRule ^.*$ - [NC,L] RewriteRule ^public/.*$ /public/index.php [NC,L] In the public folder there is a second htaccess file for MVC: RewriteEngine On RewriteCond %{REQUEST_FILENAME} -s [OR] RewriteCond %{REQUEST_FILENAME} -l [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^.*$ - [NC,L] RewriteRule ^.*$ /index.php [NC,L] # Turn off magic quotes #php_flag magic_quotes_gpc off

  • How to access "Custom" or non-System TFS workitem fields using PowerShell?

    - by DaBozUK
    When using PowerShell to extract information from TFS, I find that I can get at the standard fields but not "Custom" fields. I'm not sure custom is the correct term, but for example if I look at the Process Editor in VS2008 and edit the Work Item type, there are fields such as listed below, with Name, Type and RefName: Title String System.Title State String System.State Rev Integer System.Rev Changed By String System.ChangedBy I can access these with Get-TfsItemHistory: Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table Title, State, Rev, ChangedBy -Auto So far so good. However, there are also some other fields in the WorkItem type, which I'm calling "Custom" or non-System fields, e.g.: Activated By String Microsoft.VSTS.Common.ActivatedBy Resolved By String Microsoft.VSTS.Common.ResolvedBy And the following command does not retrieve the data, just spaces. Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table ActivatedBy, ResolvedBy -Auto I've also tried the names in quotes, the fully qualified refname, but no luck. How do you access these "non-System" fields? Thanks Boz UPDATE: From Keith's answer I can get the fields I need: Get-TfsItemHistory "$/Hermes/Main" -Version "D01/12/10~" -Recurse ` | Select ChangeSetId, Comment -exp WorkItems ` | Select ChangeSetId, Comment, @{n='WI-Id'; e={$_.Id}}, Title -exp Fields ` | Where {$_.ReferenceName -eq 'Microsoft.VSTS.Common.ResolvedBy'} ` | Format-Table ChangesetId, Comment, WI-Id, Title, @{n='Resolved By'; e={$_.Value}} -Auto

  • Setting Up OpenCV and .lib files

    - by jhaip
    I have been trying to set up OpenCV for the past few days with no results. I am using Windows 7 and VS C++ 2008 express edition. I have downloaded and installed OpenCV 2.1 and some of the examples work. I downloaded CMake and ran it to generate the VS project files and built all of them but there with several errors, and couldn't get any farther than that. When I ran CMake I configured it to use the VS 9 compiler, and then it brought up a list of items in red such as BUILD_EXAMPLES, BUILD_LATEX_DOCS, ect. All of them were unchecked except BUILD_NEW_PYTHON_SUPPORT, BUILD_TESTS, ENABLE_OPENMP, and OPENCV_BUILD_3RDPARTY_LIBS. I configured and generate without changing anything and then it generated the VS files such as ALL_BUILD.vcproj. I built the OpenCV VS solution in debug mode and it had 15 failures (maybe this is part of the problem or is it because I don't have python and stuff like that?) Now there was a lib folder created after building but inside there was just this VC++ Minimum Rebuild Dependency file and Program Debug Database file, both called cvhaartraining. I believe it should have created the .lib files I need instead of this. Also, the bin folder now has a folder called Debug with the same types of files with names like cv200d and cvaux200d. Believe I need those .lib files to move forward. I would also greatly appreciate if someone could direct me to a reliable tutorial to set up VS for OpenCV because I have been reading a lot of tutorials and they all say different things such as some say to configure Window's environment variables and other say files are located in folders such as OpenCV/cv which I don't have. I have gotten past the point of clear headed thinking so if anyone could offer some direction or a simple list of the files I need to link then I would be thankful. Also a side question: why when linking the OpenCV libs do you have to put them in quotes?

  • Best way to split a string by word (SQL Batch separator)

    - by Paul Kohler
    I have a class I use to "split" a string of SQL commands by a batch separator - e.g. "GO" - into a list of SQL commands that are run in turn etc. ... private static IEnumerable<string> SplitByBatchIndecator(string script, string batchIndicator) { string pattern = string.Concat("^\\s*", batchIndicator, "\\s*$"); RegexOptions options = RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.Multiline; foreach (string batch in Regex.Split(script, pattern, options)) { yield return batch.Trim(); } } My current implementation uses a Regex with yield but I am not sure if it's the "best" way. It should be quick It should handle large strings (I have some scripts that are 10mb in size for example) The hardest part (that the above code currently does not do) is to take quoted text into account Currently the following SQL will incorrectly get split: var batch = QueryBatch.Parse(@"-- issue... insert into table (name, desc) values('foo', 'if the go is on a line by itself we have a problem...')"); Assert.That(batch.Queries.Count, Is.EqualTo(1), "This fails for now..."); I have thought about a token based parser that tracks the state of the open closed quotes but am not sure if Regex will do it. Any ideas!?

  • What are some typing patterns using a standard QWERTY keyboard that work well for you as a programme

    - by OrbMan
    After hunting and pecking for about 35 years, I have decided to learn to type. I am learning QWERTY and have learned about 2/3 of the letters so far. While learning, I have noticed how asymmeterical the keyboard is, which really bothers me. (I will probably switch to a symmetrical keyboard eventually, but for now am trying to do everything as standard and "correct" as possible.) Although I am not there yet in my lessons, it seems that many of the keys I am going to use as a C# web developer are supposed to be typed by the pinky of my right hand. Are there any typing patterns you have developed that are more ergonomic (or faster) when typing large volumes of code rife with braces, colons, semi-colons and quotes? Or, should I just accept the fact that every other key is going to be hit with my right pinky? It is not that speed is such a huge concern, as much as that it seems so inefficient to rely on one finger so much... As an example, some of the conventions I use as a hunt and pecker, like typing open and close braces right away with my index and middle finger, and then hitting the left arrow key to fill in the inner content, don't seem to work as well with just a pinky. What are some typing patterns using a standard QWERTY keyboard that work really well for you as a programmer? Update: US layout and I use home row Update 2: Despite my best efforts to the contrary, people are interpreting this questionas "how do I learn to type" or "what keyboard should I use". Take it as a given, that I will learn to type, and that I will be doing so on a standard QWERTY layout keyboard, not DVORAK. I am interested in aquiring a skill that will be useful wherever I go.

  • XCode can't find headers in /usr/include

    - by mindthief
    Hi all, I'm trying to use standard system header files in my C++ XCode project: #include <openssl/bio.h> #include <openssl/ssl.h> #include <openssl/err.h> The build fails and it complains: "Openssl/bio.h: No such file or directory" I added /usr/include to the "Header Search Paths" in Project settings, but that doesn't fix it. I COULD fix it by adding the whole path like: #include </usr/include/openssl/bio.h> -- but the project is full of similar includes and I don't want to change all of them this way. Also, I feel I shouldn't have to do this. Another way to fix it would be as another thread mentioned, which is to add /usr/include to User Header Search Paths. But if I do that, then I'd have to change all the angle brackets < to quotes "", which again seems like a hack. I mean, these are standard system header files so I feel it should be something simple, not requiring these kinds of hacks. Any ideas? Thanks!

  • Ruby hpricot does not like dash in symbol, is there a workaround?

    - by eakkas
    I am trying to parse an xml file with hpricot. The xml element that I am trying to get has a dash though and hence the issue that I am facing xml <xliff xmlns="urn:oasis:names:tc:xliff:document:1.1" version="1.1"> <trans-unit> <source>"%0" can not be found. Please try again.</source> <target>"%0" can not be found.

This does not work because of the dash. If I rename the tag to transunit and edit the symbol reference accordingly everything seems to be fine. I thought using the symbol between quotes should work but hpricot does not seem to like this. Can anyone think of a workaround? Thanks in advance

  • binding nested json object value to a form field

    - by Jack
    I am building a dynamic form to edit data in a json object. First, if something like this exists let me know. I would rather not build it but I have searched many times for a tool and have found only tree like structures that require entering quotes. I would be happy to treat all values as strings. This edit functionality is for end users so it needs to be easy an not intimidating. So far I have code that generates nested tables to represent a json object. For each value I display a form field. I would like to bind the form field to the associated nested json value. If I could store a reference to the json value I would build an array of references to each value in a json object tree. I have not found a way to do that with javascript. My last resort approach will be to traverse the table after edits are made. I would rather have dynamic updates but a single submit would be better than nothing. Any ideas? // the json in files nests only a few levels. Here is the format of a simple case, { "researcherid_id":{ "id_key":"researcherid_id", "description":"Use to retrieve bibliometric data", "url_template" :[ { "name": "Author Detail", "url": "http://www.researcherid.com/rid/${key}" } ] } } $.get('file.json',make_json_form); function make_json_form(response) { dataset = $.secureEvalJSON(response); // iterate through the object and generate form field for string values. } // Then after the form is edited I want to display the raw updated json (then I want to save it but that is for another thread) // now I iterate through the form and construct the json object // I would rather have the dataset object var updated on focus out after each edit. function show_json(form_id){ var r = {}; var el = document.getElementById(form_id); table_to_json(r,el,null); $('body').html(formattedJSON(r)); }

  • how to display my list with n amount on each line in Python

    im trying to display my list with 7 states on each line here is what i have so far, but it displays as one long string of all the states with quotes around each state. I forgot to mention that this is for my CS class and we havent learned iter yet so we not allowed to use it. the only hint i was given was to to turn STATE_LIST into a string then use '\n' to break it up state = str(STATE_LIST) displaystates = Text(Point(WINDOW_WIDTH/2, WINDOW_HEIGHT/2), state.split('\n')) displaystates.draw(win) and STATE_LIST looks like this STATE_VOTES = { "AL" : 9, # Alabama "AK" : 3, # Alaska "AZ" : 11, # Arizona "AR" : 6, # Arkansas "CA" : 55, # California "CO" : 9, # Colorado "CT" : 7, # Connecticut "DE" : 3, # Delaware "DC" : 3, # Washington DC "FL" : 29, # Florida "GA" : 16, # Georgia "HI" : 4, # Hawaii "ID" : 4, # Idaho "IL" : 20, # Illinois "IN" : 11, # Indiana "IA" : 6, # Iowa "KS" : 6, # Kansas "KY" : 8, # Kentucky "LA" : 8, # Louisiana "ME" : 4, # Maine "MD" : 10, # Maryland "MA" : 11, # Massachusetts "MI" : 16, # Michigan "MN" : 10, # Minnesota "MS" : 6, # Mississippi "MO" : 10, # Missouri "MT" : 3, # Montana "NE" : 5, # Nebraska "NV" : 6, # Nevada "NH" : 4, # New Hampshire "NJ" : 14, # New Jersey "NM" : 5, # New Mexico "NY" : 29, # New York "NC" : 15, # North Carolina "ND" : 3, # North Dakota "OH" : 18, # Ohio "OK" : 7, # Oklahoma "OR" : 7, # Oregon "PA" : 20, # Pennsylvania "RI" : 4, # Rhode Island "SC" : 9, # South Carolina "SD" : 3, # South Dakota "TN" : 11, # Tennessee "TX" : 38, # Texas "UT" : 6, # Utah "VT" : 3, # Vermont "VA" : 13, # Virginia "WA" : 12, # Washington "WV" : 5, # West Virginia "WI" : 10, # Wisconsin "WY" : 3 # Wyoming } STATE_LIST = sorted(list(STATE_VOTES.keys())) I am trying to get it to look somewhat like this

  • GWT Animation final value is not respected

    - by brad
    I have a FlowPanel that I'm trying to animate back and forth like an iphone nav. (See this post for my original question on how to do this) So I have it "working" with the code shown below. I say working in quotes because I'm finding that my final position of my scroller is not precise and always changes when scrolling. The GWT.log always says the actual values I'm looking for, so for instance with the call below to scrollTo, my GWT.log says: ScrollStart: 0 scrollStop: -246 But when I actually analyze the element in fireBug, its css, left position is never exactly -246px. Sometimes it's off by as much as 10px so my panel has just stopped scrolling before being finished. The worst part is that this nav animates back and forth, so subsequent clicks can really throw it off, and I need pixel perfect positioning otherwise the whole things looks off. I don't even know where to start with debugging this other than what I've already done. Any tips are appreciated. Code to call animation scroller = new Scroller(); scroller.scrollTo(-246,400); Animation Code public class Scroller extends Animation { private FlowPanel scroller; private final Element e; public Scroller(){ scroller = new FlowPanel(); e = scroller.getElement(); } public void scrollTo(int position, int milliseconds) { scrollStart = e.getOffsetLeft(); scrollStop = position; GWT.log("ScrollStart: " + scrollStart + " scrollStop: " + scrollStop); run(milliseconds); } @Override protected void onUpdate(double progress) { double position = scrollStart + (progress * (scrollStop - scrollStart)); e.getStyle().setLeft(position, Style.Unit.PX); } }

  • Foreign key not working in MySQL: Why can I INSERT a value that's not in the foreign column?

    - by stalepretzel
    I've created a table in MySQL: CREATE TABLE actions ( A_id int NOT NULL AUTO_INCREMENT, type ENUM('rate','report','submit','edit','delete') NOT NULL, Q_id int NOT NULL, U_id int NOT NULL, date DATE NOT NULL, time TIME NOT NULL, rate tinyint(1), PRIMARY KEY (A_id), CONSTRAINT fk_Question FOREIGN KEY (Q_id) REFERENCES questions(P_id), CONSTRAINT fk_User FOREIGN KEY (U_id) REFERENCES users(P_id)); This created the table I wanted just fine (although a "DESCRIBE actions;" command showed me that the foreign keys were keys of type MUL, and I'm not sure what this means). However, when I try to enter a Q_id or a U_id that does not exist in the questions or users tables, MySQL still allows these values. What did I do wrong? How can I prevent a table with a foreign key from accepting invalid data? If I add TYPE=InnoDB to the end, I get an error: ERROR 1005 (HY000): Can't create table './quotes/actions.frm' (errno: 150) Why might that happen? I'm told that it's important to enforce data integrity with functional foreign keys, but also that InnoDB should not be used with MySQL. What do you recommend?

  • SQL placeholder in WHERE IN issue, inserted strings fail.

    - by Alastair Pitts
    As part of my jobs, I need to writes SQL queries to connect to our PI database. To generate a query, I need to pass an array of tags (essentially primary keys), but these have to be inserted as strings. As this will be a modular query and used for multiple tags, a placeholder is being used. The query relies upon the use of the WHERE IN statement, which is where the placeholder is, like below: SELECT SUM(value * 5/1000) as "Hourly Flow [kL]" from piarchive..pitotal WHERE tag IN (?) AND time between ? and ? and timestep = '1d' and calcbasis = 'Eventweighted' and value <> '' The issue is the format in which the tags are to be passed in as. If I add them directly into the query (for testing), they go in the format (these are example numbers): '000000012','00000032','005050236','4560236' and the query looks like: SELECT SUM(value * 5/1000) as "Hourly Flow [kL]" from piarchive..pitotal WHERE tag IN ('000000012','00000032','005050236','4560236') AND time between ? and ? and timestep = '1d' and calcbasis = 'Eventweighted' and value <> '' which works. If I try and add the same tags into the placeholder, the query fails. If I only add 1 tag, with no quotes (using the placeholder), the query works. Why is this happening? Is there anyway around it?

  • How do I join three tables with SQLalchemy and keeping all of the columns in one of the tables?

    - by jimka
    So, I have three tables: The class defenitions: engine = create_engine('sqlite://test.db', echo=False) SQLSession = sessionmaker(bind=engine) Base = declarative_base() class Channel(Base): __tablename__ = 'channel' id = Column(Integer, primary_key = True) title = Column(String) description = Column(String) link = Column(String) pubDate = Column(DateTime) class User(Base): __tablename__ = 'user' id = Column(Integer, primary_key = True) username = Column(String) password = Column(String) sessionId = Column(String) class Subscription(Base): __tablename__ = 'subscription' userId = Column(Integer, ForeignKey('user.id'), primary_key=True) channelId = Column(Integer, ForeignKey('channel.id'), primary_key=True) And the SQL commands that are executed to create them: CREATE TABLE subscription ( "userId" INTEGER NOT NULL, "channelId" INTEGER NOT NULL, PRIMARY KEY ("userId", "channelId"), FOREIGN KEY("userId") REFERENCES user (id), FOREIGN KEY("channelId") REFERENCES channel (id) ); CREATE TABLE user ( id INTEGER NOT NULL, username VARCHAR, password VARCHAR, "sessionId" VARCHAR, PRIMARY KEY (id) ); CREATE TABLE channel ( id INTEGER NOT NULL, title VARCHAR, description VARCHAR, link VARCHAR, "pubDate" TIMESTAMP, PRIMARY KEY (id) ); NOTE: I know user.username should be unique, need to fix that, and I'm not sure why SQLalchemy creates some row names with the double-quotes. And I'm trying to come up with a way to retrieve all of the channels, as well as an indication on what channels one particular user (identified by user.sessionId together with user.id) has a subscription on. For example, say we have four channels: channel1, channel2, channel3, channel4; a user: user1; who has a subscription on channel1 and channel4. The query for user1 would return something like: channel.id | channel.title | subscribed --------------------------------------- 1 channel1 True 2 channel2 False 3 channel3 False 4 channel4 True This is a best-case result, but since I have absolutely no clue as how to accomplish the subscribed column, I've been instead trying to get the particular users id in the rows where the user has a subscription and where a subscription is missing, just leave it blank. The database engine that I'm using together with SQLalchemy atm. is sqlite3 I've been scratching my head over this for two days now, I've no problem joining together all three by way of the subscription table but then all of the channels where the user does not have a subscription gets omitted. I hope I've managed to describe my problem sufficiently, thanks in advance.

  • Query to MySQL from c# returns System.Byte[]

    - by karthik
    I am using the below SP to return the value of Generated Insert statement and it works fine when executed in Query browser. When i try to get the value from C#, it give's me "System.Byte[]" as return value. When i try to get the value from MySql query browser, it give's me return value as : 'insert into admindb.accounts values("54321","2","karthik2","karthik2","1");' I guess the problem is with the single quotes of the returned value. Is it so ? DELIMITER $$ DROP PROCEDURE IF EXISTS `admindb`.`InsGen` $$ CREATE DEFINER=`root`@`localhost` PROCEDURE `InsGen`( in_db varchar(20), in_table varchar(20), in_ColumnName varchar(20), in_ColumnValue varchar(20) ) BEGIN declare Whrs varchar(500); declare Sels varchar(500); declare Inserts varchar(2000); declare tablename varchar(20); declare ColName varchar(20); set tablename=in_table; # Comma separated column names - used for Select select group_concat(concat('concat(\'"\',','ifnull(',column_name,','''')',',\'"\')')) INTO @Sels from information_schema.columns where table_schema=in_db and table_name=tablename; # Comma separated column names - used for Group By select group_concat('`',column_name,'`') INTO @Whrs from information_schema.columns where table_schema=in_db and table_name=tablename; #Main Select Statement for fetching comma separated table values set @Inserts=concat("select concat('insert into ", in_db,".",tablename," values(',concat_ws(',',",@Sels,"),');') as MyColumn from ", in_db,".",tablename, " where ", in_ColumnName, " = " , in_ColumnValue, " group by ",@Whrs, ";"); PREPARE Inserts FROM @Inserts; EXECUTE Inserts; END $$ DELIMITER ;
