  • Read and write .NET Objects in SQL Database without serialization.

    - by Mohit
    Hello, I have a small query. I need to create a Caching Service of my own that will write and read .NET Objects to and from the Database. Now, I have achieved that with the help of Binary Serialization. But the Problem is I need to deliberately marked my objects as [Serializable], which makes me think that what if someone will try to add an object which is not marked as [Serializable]. Thus, I need to find a way to read and write Objects to Database without Serialization. I have one thought too.. As we all know Session can store any object in it. Now, we can make sessions to be stored in the DB, outproc. What mechanism it uses to store these objects without serializing or deserializing. Any help will be highly appreciated. Thanks. M.B

  • Get top 'n' records by report_id

    - by Skudd
    I have a simple view in my MSSQL database. It consists of the following fields: report_id INT ym VARCHAR -- YYYY-MM keyword VARCHAR(MAX) visits INT I can easily get the top 10 keyword hits with the following query: SELECT TOP 10 * FROM top_keywords WHERE ym BETWEEN '2010-05' AND '2010-05' ORDER BY visits DESC Now where it gets tricky is where I have to get the top 10 records for each report_id in the given date range (ym BETWEEN @start_date AND @end_date). How would I go about getting the top 10 for each report_id? I've stumbled across suggestions involving the use of ROW_NUMBER() and RANK(), but have been vastly unsuccessful in their implementation.

  • Objective-C: how to splt a string constant across multiple lines

    - by Ilya
    Hi, I have a pretty long sqlite query: const char *sql_query = "SELECT statuses.word_id FROM lang1_words, statuses WHERE statuses.word_id = lang1_words.word_id ORDER BY lang1_words.word ASC"; How can I break it in a number of lines to make it easier to read? If I do the following: const char *sql_query = "SELECT word_id FROM table1, table2 WHERE table2.word_id = table1.word_id ORDER BY table1.word ASC"; I am getting a error. Is there a way to write queries in multiple lines? Thank you.

  • Sqlalchemy: Many to Many relationship error

    Dear everyone, I am following the Many to many relationship described on http://www.sqlalchemy.org/docs/mappers.html#many-to-many #This is actually a VIEW tb_mapping_uGroups_uProducts = Table( 'mapping_uGroups_uProducts', metadata, Column('upID', Integer, ForeignKey('uProductsInfo.upID')), Column('ugID', Integer, ForeignKey('uGroupsInfo.ugID')) ) tb_uProducts = Table( 'uProductsInfo', metadata, Column('upID', Integer, primary_key=True) ) mapper( UnifiedProduct, tb_uProducts) tb_uGroupsInfo = Table( 'uGroupsInfo', metadata, Column('ugID', Integer, primary_key=True) ) mapper( UnifiedGroup, tb_uGroupsInfo, properties={ 'unifiedProducts': relation(UnifiedProduct, secondary=tb_mapping_uGroups_uProducts, backref="unifiedGroups") }) where the relationship between uProduct and uGroup are N:M.

  • Obtaining kerning information

    - by chadb
    How can I obtain kerning information for GDI to then use in GetKerningPairs? The documentation states that The number of pairs in the lpkrnpair array. If the font has more than nNumPairs kerning pairs, the function returns an error. However, I do not know how many pairs to pass in, and I don't see a way to query for it. EDIT I tried to do the following, however, it still gave me 0. Font* myFont = new Font(L"Times New Roman", 10); Bitmap* bitmap = new Bitmap(256, 256, PixelFormat32bppARGB); Graphics* g = new Graphics(bitmap); SelectObject(g->GetHDC(), myFont); //DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), -1, NULL ); DWORD numberOfKerningPairs = GetKerningPairs( g->GetHDC(), INT_MAX, NULL );

  • Bash intercepting wildcard in script

    - by MrRoth
    I am using Bash script to read line by line from a text file, which has special characters in it (regular expression). When I use echo "${SOME_VAR}" it does not display the text as is. I am familiar with Prevent * to be expanded in the bash script. How can I display and use the text as is? UPDATE The text (TSV) file holds tuples similar to (the last entry is a psql query) bathroom bathroom select name from photos where name ~* '\mbathroom((s)?|(''s)?)\M'; I am reading the CSV as follows: tail -n+2 text.file | while IFS=$'\t' read x y z do echo "${z}" done which gives the output select name from photos where name ~* 'mbathroom((s)?|(''s)?)M'); note that the '\' is missing

  • does a git repository have its own local value for core.autocrlf that overrides the global one?

    - by Warren P
    As per this question, I understand that core.autocrlf=true in git will cause CRLF to LF translations. However when I type : git config core.autocrlf I see: false However, when I stage modified files that are already in the repo, I still get these warnings: Warning: CRLF will be replaced by LF in File1.X. The file will have its original line endings in your working directory. My guess is that the repo copy of the file is already set to "autocrlf=true". Questions: A. How do I query whether a file or git repo is already forcing AutoCrlf? B. How do I turn it autocrlf off?

  • Select rows where column LIKE dictionary word

    - by Gerve
    I have 2 tables: Dictionary - Contains roughly 36,000 words CREATE TABLE IF NOT EXISTS `dictionary` ( `word` varchar(255) NOT NULL, PRIMARY KEY (`word`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; Datas - Contains roughly 100,000 rows CREATE TABLE IF NOT EXISTS `datas` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `hash` varchar(32) NOT NULL, `data` varchar(255) NOT NULL, `length` int(11) NOT NULL, `time` int(11) NOT NULL, PRIMARY KEY (`ID`), UNIQUE KEY `hash` (`hash`), KEY `data` (`data`), KEY `length` (`length`), KEY `time` (`time`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=105316 ; I would like to somehow select all the rows from datas where the column data contains 1 or more words. I understand this is a big ask, it would need to match all of these rows together in every combination possible, so it needs the best optimization. I have tried the below query, but it just hangs for ages: SELECT `datas`.*, `dictionary`.`word` FROM `datas`, `dictionary` WHERE `datas`.`data` LIKE CONCAT('%', `dictionary`.`word`, '%') AND LENGTH(`dictionary`.`word`) > 3 ORDER BY `length` ASC LIMIT 15 I have also tried something similar to the above with a left join, and on clause that specified the like statement.

  • How to coerce type of ActiveRecord attribute returned by :select phrase on joined table?

    - by tribalvibes
    Having trouble with AR 2.3.5, e.g.: users = User.all( :select => "u.id, c.user_id", :from => "users u, connections c", :conditions => ... ) Returns, e.g.: => [#<User id: 1000>] >> users.first.attributes => {"id"=>1000, "user_id"=>"1000"} Note that AR returns the id of the model searched as numeric but the selected user_id of the joined model as a String, although both are int(11) in the database schema. How could I better form this type of query to select columns of tables backing multiple models and retrieving their natural type rather than String ? Seems like AR is punting on this somewhere. How could I coerce the returned types at AR load time and not have to tack .to_i (etc.) onto every post-hoc access?

  • check for several conditions when a user logs in

    - by paul
    I would like to accomplish the following: If a username or password field is null, notify the user. If user name already exists, do not insert into the database and notify user to create a different name. if the username is unique and password is not null, return the username to the user. As of now it always returns "Please enter a different user name." I believe the issue has to do with the database query but I am not sure. If anyone can have a look and see if I am making an error, I greatly appreciate it, thanks. if ($userName or $userPassword = null) { echo "Please enter a user name and password or return to the homepage."; } elseif (mysql_num_rows(mysql_query("SELECT count(userName) FROM logininfo WHERE userName = '$userName'")) ==1) { echo "Please enter a different user name."; } elseif ($userName and $userPassword != null) { echo "Your login name is: $userName"; }

  • How do I declare a C# Web User Control but stop it from initializing?

    - by Scott Stafford
    I have a C#/ASP.NET .aspx page that declares two controls that each represents the content of one tab. I want a query string argument (e.g., ?tab=1) to determine which of the two controls is activated. My problem is, they both go through the initialization events and populate their child controls, wasting CPU resources and slowing the response time. Is it possible to deactivate them somehow so they don't go through any initialization? My .aspx page looks like this: <% if (TabId == 0) { %> <my:usercontroltabone id="ctrl1" runat="server" /> <% } else if (TabId == 1) { %> <my:usercontroltabtwo id="ctrl2" runat="server" /> <% } %> And that part works fine. I assumed the that <%'s would have meant the control wouldn't actually be declared and so wouldn't initialize, but that isn't so...

  • Getting certain array from a multidimensional array

    - by Leron
    I have multidimensional array which is a query returning the info from a table named 'users'. In another part of my code I need to get the records of only one certain user and I want to take it using the array I mentioned above. It's of type: array(24) { [0]=>array(9) { ["id"]=>string(1) "1" ... } [1]=>array(9) { ["id"]=>string(1) "2" ... } [2]=>array(9) { ["id"]=>string(1) "5" ...} I'll use foreach compairing by ["id"] to find the record I need, but when I get a match I'm not sure how to extract only this array from the parent one. Thanks Leron

  • SQL - Break a start/end time into 15 minute records

    - by Chu
    I've got a record set that consists of a start and end time in two separate fields: id - Int startTime - DateTime endTime - DateTime I'd like to find a way to query a record and return it as X records based on the number of 15 minute intervals found between the start and end times. For example, let's say I have a record like this: id, StartTime, EndTime 1, 1/1/2010 8:28 AM, 1/1/2010 8:47 AM I would return 3 records, the first would represent the 8:15 interval, #2 for the 8:30 interval and then a 3rd for the 8:45 interval. I realize this could be done using logic in an sproc, but we are trying to remain db neutral as we support multiple database engines.

If anyone could shed some light on a possible solution, it would be greatly appreciated.

  • API for configuring static IP addresses in an android application

    - by awoodland
    Is it possible to set the IP address of an interface in Android within an application? I can query the available interfaces and their current addresses using java.net.NetworkInterface, but this doesn't provide a facility to change these. Did I just miss something somewhere or is it not allowed? I was hoping to be able to make my application either change or add an alias to one or more of the existing interfaces at runtime on an "off the shelf" device. (2.1/2.2). Ideally I'd like to do this for both IPv4 and v6 addresses.

  • Stackoverflow interesting tags

    - by Tom
    So, that's how works Interesting Tags: I add into them my interested tags like php, mysql, jquery and so on. Then, if any of questions has the same tags as mine it makes background orange. I understand how to use jquery to do that (there were related questions to that), but without mysql it can't be done. Now, here is a question. How is it done? I imagine like that: There is a row in mysql for every member, let's call it "interested_tags". After I write and submit my tag through input, it is being written in a row "interested_tags". Then, the main page has a query which shows all answers and it always checks answer's with mine tags with strpos like this if(strpos($question_tags, $my_tags) === true) {        //and here will be made background orange } Am I thinking right or is there any way to do it?

  • Stored procedure for selecting multiple records

    - by padmavathi
    I need to select records say 2000 from a table with a matching timestamp from c# .net code. Eg: SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME='Item1' and TimeStamp='2010-04-26 17:15:05.667' The above query has to execute for 2000 items more for the same timestamp. for this we can use SELECT * FROM ITEMDATA_TABLE WHERE ITEMNAME in ('Item1','Item2','Item3','Item4',......) AND TimeStamp='2010-04-26 17:15:05.667' from SQL Server Management Studio. I have tried appending all Item names to one string variable and giving it as a parameter to the stored procedure,but it resulted into a wrong concatenation. How can I do this as a stored procedure executing from the .net code? Can anyone suggest me/correct me in doing this? Thanks & Regards Padma

  • filter queryset based on list, including None

    - by jujule
    Hi all I dont know if its a django bug or a feature but i have a strange ORM behaviour with MySQL. class Status(models.Model): name = models.CharField(max_length = 50) class Article(models.Model) status = models.ForeignKey(status, blank = True, null=True) filters = Q(status__in =[0, 1,2] ) | Q(status=None) items = Article.objects.filter(filters) this returns Article items but some have other status than requested [0,1,2,None] looking at the sql query : SELECT [..] FROM `app_article` LEFT OUTER JOIN `app_status` ON (`app_article`.`status_id` = `app_status`.`id`) WHERE (`app_article`.`status_id` IN (1, 2) OR `app_status`.`id` IS NULL) ORDER BY [...] the OR app_status.id IS NULL part seems to be the cause. if i change it to OR app_article.status_id IS NULL it works correctly. How to deal with this ? Thanx.

  • Converting Informix 'Perform' screens to a Windows-based application

    - by Lunthita
    For the past several years we have slowly built an Access-based front end to access our InformixSE database (unix). Our Sun server will be shut down in a couple of months and I'm looking for a relatively inexpensive solution for porting over the remainder of our old ".per" screens to a Windows-based solution. And even for the screens that have been reprogrammed, there's nothing that beats being able to query any field on the screen like you could with those simple-to-get-up-and-running Informix "Perform" screens. Does anyone have experience with a solution?

  • How to force ListView to show first page programmatically

    - by doekman
    I have a paged ASP.NET ListView. The data shown is filtered, which can be controlled by a form. When the filter form changes, I create a new query, and perform a DataBind. The problem however, when I go to the next page, and set a filter, the ListView shows "No data was returned". That is not weird, because after the filter is applied, there is only one page of data. So what I want to do is reset the pager. Is that a correct solution to the problem? And how do I do that?

  • How do I get this php statement that gets all the values from database and outputs as checkboxes to

    - by ggfan
    I am a bit lost in all these "" and '' and . in this statement. Basically this query is to get all the tagname from table "tag" and display them for the users as checkboxes. If they have clicked 'submit' and they missed another field(say the title of a post), it would still have the tag they chose displayed. The part I need help with is the echoing part. It doesn't seem to remember the tag when they click submit. $query4 = "SELECT * FROM tags ORDER BY tagname"; $data4 = mysqli_query($dbc, $query4); while ($row4 = mysqli_fetch_array($data4)) { echo "<li><input type='checkbox' name='postingtag[]'"; if (!empty($postingtag)){ echo "value='$postingtag'"; } else{ echo "value='{$row4['tagID']}'"; } echo ">{$row4['tagname']}</li>"; }
