  • PHP 'smart' search engine to search Mysql tables advice

    - by Anonymous12345
    I am creating a search engine for my php based website. I need to search a mysql table. Thing is, the search engine must be pretty 'smart', so that users can easily find their items (it's a classifieds website). I have currently set up a FULLTEXT search with this piece of code: MATCH (headline) AGAINST ($querystring) But this isn't enough... For instance, lets say the field headline contains something like Bmw 330ci. If I search for 330, I wont get any results. The ending ('ci') is just one of many endings in car models which must be taken into account when searching the table. Or what if the headline field is bmw330? Also no results, because it only matches full words. Or also, what if the headline is bmw 330, and I search for bmw 520, still with FULLTEXT I will get the bmw 330 as a result, even though I searched for bmw 520... Not good! How should I solve this problem?

  • Saving multiple items per single database cell...

    - by eugeneK
    Hi, i have a countries list. Each user can check multiple countries. Once saved, this "user country list" will be used to get whether other users fit into countries certain user chose. Question is what would be the most efficient approach to this problem... I have one, one to save user selection as delimited list like Canada,USA,France ... in single varchar(max) field but problem with it would be that once user from Germany enters page i perform this check on. To search for Germany i would be needed to get all items and un-delimit each field to check against value or to use sql 'like' which again is pretty damn slow.. If you have better solution or some tips i would be glad to hear. Just to make sure, many users will have their own selections of countries from which and only they want to have users to land on their page. While millions of users will reach those pages. So the faster approach will be the better. technology, MSSQL and ASP.NET thanks

  • What noncluster index would be better to create on SQL Server?

    - by Junior Mayhé
    Here I am studying nonclustered indexes on SQL Server Management Studio. I've created a table with more than 1 million records. This table has a primary key. SELECT CustomerName FROM Customers Which leads the execution plan to show me: I/O cost = 3.45646 Operator cost = 4.57715 For the first attempt to improve performance, I've created a nonclustered index for this table: CREATE NONCLUSTERED INDEX [IX_CustomerID_CustomerName] ON [dbo].[Customers] ( [CustomerId] ASC, [CustomerName] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO With this first try, I've executed the select statement and the execution plan shows me: I/O cost = 2.79942 Operator cost = 3.92001 Now the second try, I've deleted this nonclustered index in order to create a new one. CREATE NONCLUSTERED INDEX [IX_CategoryName] ON [dbo].[Categories] ( [CategoryId] ASC ) INCLUDE ( [CategoryName]) WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO With this second try, I've executed the select statement and the execution plan shows me the same result: I/O cost = 2.79942 Operator cost = 3.92001 Am I doing something wrong or this is expected? Shall I use the first nonclustered index with two fields, or the second nonclustered with one field (CategoryID) including the second field (CategoryName)?

  • Pop-up and font colour based problems in a form which is designed in Share Point.

    - by ephieste
    I am designing a system in Share Point via Share Point Designer. We have a form in my Share Point site. Users have to fill some fields in the form and send it to the approval committee. We cannot upload anything to the servers. The design is site based. Our problems are: 1- I want to add small (?) icons for the descriptions of that field. When the user click on the (?) icon for "brief description" field a pop-up or another window will be opened and perhaps it will say: Enter a description of the requested thing. Be as specific as possible. 2- I want to change the font colors of the fields in the form. The share point brings them black as default. Such as I want to see the "Brief description:" and "Status:" as purple instead of black. Brief description: ..... Status: ..... 3- I want to add an agreement pop-up to the new form which will be open just after clicking "send" button in the form. The pop up will say: "Are you sure that you read the procedure" . The user has to click "Yes" to continue sending the form. Otherwise It will return to previous screen again. I would be glad if you kindly help me.

  • Mysql random rows

    - by n00b
    please read the whole question... 90% of you dont seem to do that and some of you only read the title obviously... and if you dont know the solution, dont answer - i wont have to downvote you -.-'' im entertaining the idea of getting random rows directly from mysql. what i found was SELECT * FROM tablename WHERE somefield='something' ORDER BY RAND() LIMIT 5 but even i see how slow that would be.. is the only way to do this doing something like SELECT * FROM tablename WHERE somefield='something' LIMIT RAND(aincrementvalue-5), 1 5 times? or is there a way that i with my little knowlege of databases cant come up with ? (no i dont want random indexes. i hate the idea of them...) @commenters - please first look, then think, then look again, think again and then post. i wont point fingers but i dislike stupid comments and why i think random indexes are a nasty hack ? it doesnt give you random results. it gives you x results from a random index in a predefined order its like a gapless id only in the wrong order if you fetch by 1 row and get true randomness you fall back to my method but with an additional junk field finally the reason the field exists is only to serve as a helper to something that can be done without it with almost same performance (but the quality (randomness) is better), so it is a nasty hack ;) i solved it, look @ my answer... if you think its incorrect please tell me :)

  • C# Virtual method call in constructor - how to refactor?

    - by Cristi Diaconescu
    I have an abstract class for database-agnostic cursor actions. Derived from that, there are classes that implement the abstract methods for handling database-specific stuff. The problem is, the base class ctor needs to call an abstract method - when the ctor is called, it needs to initialize the database-specific cursor. I know why this shouldn't be done, I don't need that explanation! This is my first implementation, that obviously doesn't work - it's the textbook "wrong way" of doing it. The overridden method accesses a field from the derived class, which is not yet instantiated: public abstract class CursorReader { private readonly int m_rowCount; protected CursorReader() { m_rowCount = CreateCursor(sqlCmd); //virtual call ! } protected abstract int CreateCursor(string sqlCmd); } public class SqlCursorReader : CursorReader { private SqlConnection m_sqlConnection; public SqlCursorReader(string sqlCmd, SqlConnection sqlConnection) { m_sqlConnection = sqlConnection; //field initialized here } protected override int CreateCursor(string sqlCmd) { //uses not-yet-initialized member *m_sqlConnection* //so this throws a NullReferenceException var cursor = new CustomCursor(sqlCmd, m_sqlConnection); return cursor.Count(); } } I will follow up with an answer on my attempts to fix this...

  • Testing form submission with Cucumber

    - by picardo
    I wrote a simple Cuke feature for a form on a demo site. The feature looks like this. Given I am on the home page When I set the "Start Date" to "2010-10-25" And I set the "End Date" to "2011-1-3" And I press the "Go" button Then I should see "Cake Shop" The idea is that after I press the Go button, a new page will load, showing a list of results, and one of the results should be "Cake Shop." But I have not managed to get this to work. Is there something that I am missing? Edit: here is the step definitions. Given /^I am on the "([^"]*)" page$/ do |page| visit root_path end When /^I set the "([^"]*)" to "([^"]*)"$/ do |field, date| fill_in field, :with=>date end When /^I press the "([^"]*)" button$/ do |arg1| click_button('Go') end The final step is defined in web_steps.rb I believe....and it's always there that it's failing. Then I should see "Cake Shop" # features/step_definitions/web_steps.rb:107 expected #has_content?("Cake Shop") to return true, got false (RSpec::Expectations::ExpectationNotMetError) ./features/step_definitions/web_steps.rb:110:in block (2 levels) in <top (required)>' ./features/step_definitions/web_steps.rb:14:in with_scope' ./features/step_definitions/web_steps.rb:108:in /^(?:|I )should see "([^"]*)"(?: within "([^"]*)")?$/' features/specify_timerange.feature:12:in Then I should see "Cake Shop"'

  • OpenSocial create activity from submit click

    - by russp
    Hi I'm "playing with OpsnSocial" and think I get a lot of it (well thanks to Googles' bits) but one question if I may. Creating an activity Lets say I have a form like this (simple) <form> <input type="text" name="" id="testinput" value=""/> <input type="submit" name="" id="" value=""/> </form> And I want to post the value of the text field (and or a message i.e "just posted" to the "users" activity. Do I use a function like this? function createActivity() { if (viewer) { var activity = opensocial.newActivity({ title: viewer.getDisplayName() + ' VALUE FROM FORM '}); opensocial.requestCreateActivity(activity, "HIGH", function() { setTimeout(initAllData,1000); }); } }; If so, how do I pass the text field value to it - is it something like this? var testinput = document.getElementById("testinput"); so the function may look like function createActivity() { if (viewer) { var activity = opensocial.newActivity({ title: viewer.getDisplayName() + testinput }); opensocial.requestCreateActivity(activity, "HIGH", function() { setTimeout(initAllData,1000); }); } }; And how do I trigger the function by using the submit button. In my basic JQuery I would use $('#submitID').submit(function(){ 'bits in here '}); Is at "simple as that i.e. use the createActivity function and it will use the OS framework to "post" to the activity.xml

  • Java - How to find the redirected url of a url?

    - by Yatendra Goel
    I am accessing web pages through java as follows: URLConnection con = url.openConnection(); But in some cases, a url redirects to another url. So I want to know the url to which the previous url redirected. Below are the header fields that I got as a response: null-->[HTTP/1.1 200 OK] Cache-control-->[public,max-age=3600] last-modified-->[Sat, 17 Apr 2010 13:45:35 GMT] Transfer-Encoding-->[chunked] Date-->[Sat, 17 Apr 2010 13:45:35 GMT] Vary-->[Accept-Encoding] Expires-->[Sat, 17 Apr 2010 14:45:35 GMT] Set-Cookie-->[cl_def_hp=copenhagen; domain=.craigslist.org; path=/; expires=Sun, 17 Apr 2011 13:45:35 GMT, cl_def_lang=en; domain=.craigslist.org; path=/; expires=Sun, 17 Apr 2011 13:45:35 GMT] Connection-->[close] Content-Type-->[text/html; charset=iso-8859-1;] Server-->[Apache] So at present, I am constructing the redirected url from the value of the Set-Cookie header field. In the above case, the redirected url is copenhagen.craigslist.org Is there any standard way through which I can determine which url the particular url is going to redirect. I know that when a url redirects to other url, the server sends an intermediate response containing a header field that tells the url which it is going to redirect but I am not receiving that intermediate response through the url.openConnection(); method.

  • Using CookieJar in Python to log in to a website from "Google App Engine". What's wrong here?

    - by brilliant
    Hello everybody, I've been trying to find a python code that would log in to my mail box on yahoo.com from "Google App Engine" . Here (click here to see that page) I was given this code: import urllib, urllib2, cookielib url = "https://login.yahoo.com/config/login?" form_data = {'login' : 'my-login-here', 'passwd' : 'my-password-here'} jar = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(jar)) form_data = urllib.urlencode(form_data) # data returned from this pages contains redirection resp = opener.open(url, form_data) # yahoo redirects to http://my.yahoo.com, so lets go there instead resp = opener.open('http://mail.yahoo.com') print resp.read() The author of this script looked into HTML script of yahoo log-in form and came up with this script. That log-in form contains two fields, one for users' Yahoo! ID and another one is for users' password. Here is how HTML code of that page for both of those fields looks like: User ID field: <input type="text" maxlength="96" class="yreg_ipt" size="17" value="" id="username" name="login"> Password field: <input type="password" maxlength="64" class="yreg_ipt" size="17" value="" id="passwd" name="passwd"> However, when I uploaded this code to Google App Engine I discovered that this log-in form keeps coming back to me, which, I assume, means that logging-in process didn't succeed. Why is it so?

  • how can i check ID of a clicked element js

    - by necker
    how can i check if an ID of a clicked element is lets say 'target'. what i am trying to do is actually show and hide comment form on clicking in the text field and hide it when the user clicks out of the form. the problem is that if the user clicks Submit button the form hides and nothing is sent over. so i'll have to check if the submit buttons id matches the clicked element and not hide it in this case. i am using ruby on rails remote_form_for and onblur and onfocus events now. this is my bigger form that i am showing. <div id="bigArea" style="display:none"> <% remote_form_for @horses do |f|%> <%= f.text_area :description, {:onBlur=>"{$(bigArea').hide();$('smallField').show();}"} %> <%= f.submit "Submit"%> <% end %> </div> and this is the smaller form field that hides everytime you click in it. <div id="smallField"> <%= text_field_tag 'sth',"Click to comment, {:onFocus=>"$('bigArea').show();$('smallField').hide();"} %> </div> My question is how can i disallow the form to hide when a user clicks submit button? i suppose i should check which element's id has been clicked. and if it's submit button's ID i should not hide the form. Or maybe there is some other way to do all this? i would greatly appreciate any answers!

  • Is going for a BCS the right move for me?

    - by Michel Carroll
    I'm at a fork in the road. I need somebody to give me some advice from their personal journey in IT. At the moment, I have a college diploma (2 years) in Computer Programmer, and about 2 years of professional experience in the field of software. I'm currently freelancing my programming skills to the public, and am enjoying a nice income, and the rewards of flexibly working on a variety of projects with different cool people. I'm young (21 years old), passionate about software, technology, the internet, and also business. I know if I ever want to dwell deeper into the software industry, I might have a hard time doing so without a Bachelors in Computer Science. On one side, I think I'm better off getting my BCS while I'm still young and malleable. Also, the thought of learning even more stuff in my field is really exciting to me. On the flip side, it means another 3-4 years of studying, and jeopardizing my chances of going on vacation and accumulating wealth for a long time. Considering that I'm already pretty successful with my college diploma, do you think it's a good idea for me to go get my BCS? Will it open up many more doors in the future?

  • How to create C++ istringstream from a char array with null(0) characters?

    - by Morpheus
    I have a char array which contains null characters at random locations. I tried to create an iStringStream using this array (encodedData_arr) as below, I use this iStringStream to insert binary data(imagedata of Iplimage) to a MySQL database blob field(using MySQL Connector/C++'s setBlob(istream *is) ) it only stores the characters upto the first null character. Is there a way to create an iStringStream using a char array with null characters? unsigned char *encodedData_arr = new unsigned char[data_vector_uchar->size()]; // Assign the data of vector<unsigned char> to the encodedData_arr for (int i = 0; i < vec_size; ++i) { cout<< data_vector_uchar->at(i)<< " : "<< encodedData_arr[i]<<endl; } // Here the content of the encodedData_arr is same as the data_vector_uchar // So char array is initializing fine. istream *is = new istringstream((char*)encodedData_arr, istringstream::in || istringstream::binary); prepStmt_insertImage->setBlob(1, is); // Here only part of the data is stored in the database blob field (Upto the first null character)

  • Compound Primary Key in Hibernate using Annotations

    - by Rich
    Hi, I have a table which uses two columns to represent its primary key, a transaction id and then the sequence number. I tried what was recommended http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-mapping in section 2.2.3.2.2, but when I used the Hibernate session to commit this Entity object, it leaves out the TXN_ID field in the insert statement and only includes the BA_SEQ field! What's going wrong? Here's the related code excerpt: @Id @Column(name="TXN_ID") private long txn_id; public long getTxnId(){return txn_id;} public void setTxnId(long t){this.txn_id=t;} @Id @Column(name="BA_SEQ") private int seq; public int getSeq(){return seq;} public void setSeq(int s){this.seq=s;} And here are some log statements to show what exactly happens to fail: In createKeepTxnId of DAO base class: about to commit Transaction :: txn_id->90625 seq->0 ...<Snip>... Hibernate: insert into TBL (BA_ACCT_TXN_ID, BA_AUTH_SRVC_TXN_ID, BILL_SRVC_ID, BA_BILL_SRVC_TXN_ID, BA_CAUSE_TXN_ID, BA_CHANNEL, CUSTOMER_ID, BA_MERCHANT_FREETEXT, MERCHANT_ID, MERCHANT_PARENT_ID, MERCHANT_ROOT_ID, BA_MERCHANT_TXN_ID, BA_PRICE, BA_PRICE_CRNCY, BA_PROP_REQS, BA_PROP_VALS, BA_REFERENCE, RESERVED_1, RESERVED_2, RESERVED_3, SRVC_PROD_ID, BA_STATUS, BA_TAX_NAME, BA_TAX_RATE, BA_TIMESTAMP, BA_SEQ) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) [WARN] util.JDBCExceptionReporter SQL Error: 1400, SQLState: 23000 [ERROR] util.JDBCExceptionReporter ORA-01400: cannot insert NULL into ("SCHEMA"."TBL"."TXN_ID") The important thing to note is I print out the entity object which has a txn_id set, and then the following insert into statement does not include TXN_ID in the listing and thus the NOT NULL table constraint rejects the query.

  • Return value mapping on Stored Procedures in Entity Framework

    - by Yucel
    Hi, I am calling a stored procedure with EntityFramework. But custom property that i set in partial entity class is null. I have Entities in my edmx (I called edmx i dont know what to call for this). For example I have a "User" table in my database and so i have a "User" class on my Entity. I have a stored procedure called GetUserById(@userId) and in this stored procedure i am writing a basic sql statement like below "SELECT * FROM Users WHERE Id=@userId" in my edmx i make a function import to call this stored procedure and set its return value to Entities (also select User from dropdownlist). It works perfectly when i call my stored procedure like below User user = Context.SP_GetUserById(123456); But i add a custom new column to stored procedure to return one more column like below SELECT *, dbo.ConcatRoles(U.Id) AS RolesAsString FROM membership.[User] U WHERE Id = @id Now when i execute it from SSMS new column called RolesAsString appear in result. To work this on entity framework i added a new property called RolesAsString to my User class like below. public partial class User { public string RolesAsString{ get; set; } } But this field isnt filled by stored procedure when i call it. I look to the Mapping Detail windows of my SP_GetUserById there isnt a mapping on this window. I want to add but window is read only i cant map it. I looked to the source of edmx cant find anything about mapping of SP. How can i map this custom field?

  • How can I use SQL to select duplicate records, along with counts of related items?

    - by mipadi
    I know the title of this question is a bit confusing, so bear with me. :) I have a (MySQL) database with a Person record. A Person also has a slug field. Unfortunately, slug fields are not unique. There are a number of duplicate records, i.e., the records have different IDs but the same first name, last name, and slug. A Person may also have 0 or more associated articles, blog entries, and podcast episodes. If that's confusing, here's a diagram of the structure: I would like to produce a list of records that match this criteria: duplicate records (i.e., same slug field) for people who also have at least 1 article, blog entry, or podcast episode. I have a SQL query that will list all records with the same slug fields: SELECT id, first_name, last_name, slug, COUNT(slug) AS person_records FROM people_person GROUP BY slug HAVING (COUNT(slug) > 1) ORDER BY last_name, first_name, id; But this includes records for people that may not have at least 1 article, blog entry, or podcast. Can I tweak this to fit the second criteria?

  • Presenting collection of structures of strings in grid or similar in WPF - Example? Ideas?

    - by Andrew
    Hi, I have a collection of structures. The structure is just some strings. Example public struct ReportLine { public string Name; public string Address; public string Phone; ...// about 10 other strings } I can't change this part. What I want to do is display it in a simple grid or simlar in WPF. My only requirements are: a) need column headers b) rows must alternate in color c) columns big enough to hold largest datum (which is not know until run time) Can someone point me to an example to get me started? Is the GridView the way to go? Or DataGrid? Or perhaps just the grid? I have the book Pro WPF in C# 2008 and it covers binding ListBox's to collections, but the collections always seem to be collections of one field (ex. a collection of 40 names). Here I have a collection (an array in fact) of a structure. How do I setup the databinding? As you can see, I'm new to this and probably would most benefit from a reference to an article. I've found articles covering collections of 1 field, but no examples covering binding to an array of structures. Also, my intitial research indicates c) can't be easily done, if you demand that the column is big enough for all the data in that column, not just the visible data. Thanks, dave

  • How to Map Two Tables To One Class in Fluent NHibernate

    - by Richard Nagle
    I am having a problem with fluent nhiberbate mapping two tables to one class. I have the following database schema: TABLE dbo.LocationName ( LocationId INT PRIMARY KEY, LanguageId INT PRIMARY KEY, Name VARCHAR(200) ) TABLE dbo.Language ( LanguageId INT PRIMARY KEY, Locale CHAR(5) ) And want to build the following class definition: public class LocationName { public virtual int LocationId { get; private set; } public virtual int LanguageId { get; private set; } public virtual string Name { get; set; } public virtual string Locale { get; set; } } Here is my mapping class: public LocalisedNameMap() { WithTable("LocationName"); UseCompositeId() .WithKeyProperty(x => x.LanguageId) .WithKeyProperty(x => x.LocationId); Map(x => x.Name); WithTable("Language", lang => { lang.WithKeyColumn("LanguageId"); lang.Map(x => x.Locale); }); } The problem is with the mapping of the Locale field being from another table, and in particular that the keys between those tables don't match. Whenever I run the application with this mapping I get the following error on startup: Foreign key (FK7FC009CCEEA10EEE:Language [LanguageId])) must have same number of columns as the referenced primary key (LocationName [LanguageId, LocationId]) How do I tell nHibernate to map from LocationName to Language using only the LanguageId field?

    - by tye
    If I allow a group of users to submit "explain $whatever" to mysql (via Perl's DBI using DBD::mysql), is there anything that a user could put into $whatever that would make any database changes, leak non-trivial information, or even cause significant database load? If so, how? I know that via "explain $whatever" one can figure out what tables / columns exist (you have to guess names, though) and roughly how many records are in a table or how many records have a particular value for an indexed field. I don't expect one to be able to get any information about the contents of unindexed fields. DBD::mysql should not allow multiple statements so I don't expect it to be possible to run any query (just explain one query). Even subqueries should not be executed, just explained. But I'm not a mysql expert and there are surely features of mysql that I'm not even aware of. In trying to come up with a query plan, might the optimizer actual execute an expression in order to come up with the value that an indexed field is going to be compared against? explain select * from atable where class = somefunction(...) where atable.class is indexed and not unique and class='unused' would find no records but class='common' would find a million records. Might 'explain' evaluate somefunction(...)? And then could somefunction(...) be written such that it modifies data?

  • Incorrect component when querying immediately after insert using NHibernate

    - by Am
    I have the following mapping for my table in MySql: <class name="Tag, namespace" table="tags" > <id name="id" type="Int32" unsaved-value="0"> <generator class="native"></generator> </id> <property name="name" type="String" not-null="true"></property> <component name="record_dates" class="DateMetaData, namespace" > <property name="created_at" type="DateTime" not-null="true"></property> <property name="updated_at" type="DateTime" not-null="true"></property> </component> </class> As you see the record_dates property is defined as a component field of type DateMetaDate. Both created_at and updated_at fields in 'tags' table are updated via triggers. Thus I can insert a new record like such: var newTag = new Tag() { name = "some string here" } Int32 id = (Int32)Session.Save(tag); Session.Flush(); ITag t = Session.Get<Tag>(id); ViewData["xxx"] = t.name; // -----> not null ViewData["xxx"] = t.record_dates.created_at; // -----> is null However when querying the same record back immediately after it was inserted the record_dates field ends up null even though in the table those fields have got values. Can any one please point out why the Session.Get ignores getting everything back from the table? is it because it caches the newly created record for which the records_dates is null? If so how can it be told to ignore the cached version?
