  • Java: How to have an ArrayList as instance variable of an object?

    - by JDelage
    All, I'm working on a class project to build a little Connect4 game in Java. My current thinking is to have a class of Columns that have as instance variable a few integers (index, max. length, isFull?) and one ArrayList to receive both the integers above and the plays of each players (e.g., 1's and 0's standing for X's and O's). This is probably going to be split between 2 classes but the question remains the same. My current attempt looks like this: import java.util.ArrayList; public class Conn4Col { public int hMax; public int index; public final int initialSize = 0; public final int fullCol = 0; public ArrayList<Integer>; (...)} Unfortunately, this doesn't compile. The compiler says an is missing where my ArrayList declaration stands. We're just starting objects and we haven't really looked into other instance variables than the basic types. Can someone tell me where my error is and how to correct it? Many thanks, JDelage

  • Display ASP.NET GridView inside a selected row in another GridView

    - by Justin C
    I have been given a mockup that I do not know is possible to code in ASP.NET without being a real html and javascript wizard. I want a GridView that when a row is selected, the selected row expands and below the selected row a panel of additional information is shown, which would also include another small GridView. The idea is this would all be in-line. So if the user selected row 4, then the additional information would appear below row 4 and then after the additional information the parent GridView would continue with row 5. Ultimately I would want to do a multi-select type of set up, but first I need to figure out if this is even possible. Also, the solution must be 508 Compliant The one solution I considered was using only one "column". Then I would put all my fields in the ItemTemplate, and my detail panel content in the EditItemTemplate and instead of selecting the row, set it to edit mode. The problem with this solution is I lose the functionality of multiple columns if I throw everything in one huge ItemTemplate. Any and all suggestions or ideas are appreciated.

  • How to override ATTR_DEFAULT_IDENTIFIER_OPTIONS in Models in Doctrine?

    - by user309083
    Here someone explained that setting a 'primary' attribute for any row in your Model will override Doctrine_Manager's ATTR_DEFAULT_IDENTIFIER_OPTIONS attribute: http://stackoverflow.com/questions/2040675/how-do-you-override-a-constant-in-doctrines-models This works, however if you have a many to many relation whereby the intermediate table is created, even if you have set both columns in the intermediate to primary an error still results when Doctrine tries to place an index on the nonexistant 'id' column upon table creation. Here's my code: //Bootstrap // set the default primary key to be named 'id', integer, 4 bytes Doctrine_Manager::getInstance()->setAttribute( Doctrine_Core::ATTR_DEFAULT_IDENTIFIER_OPTIONS, array('name' => 'id', 'type' => 'integer', 'length' => 4)); //User Model class User extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('users'); } public function setUp() { $this->hasMany('Role as roles', array( 'local' => 'id', 'foreign' => 'user_id', 'refClass' => 'UserRole', 'onDelete' => 'CASCADE' )); } } //Role Model class Role extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('roles'); } public function setUp() { $this->hasMany('User as users', array( 'local' => 'id', 'foreign' => 'role_id', 'refClass' => 'UserRole' )); } } //UserRole Model class UserRole extends Doctrine_Record { public function setTableDefinition() { $this->setTableName('roles_users'); $this->hasColumn('user_id', 'integer', 4, array('primary'=>true)); $this->hasColumn('role_id', 'integer', 4, array('primary'=>true)); } } Resulting error: SQLSTATE[42000]: Syntax error or access violation: 1072 Key column 'id' doesn't exist in table. Failing Query: "CREATE TABLE roles_users (user_id INT UNSIGNED NOT NULL, role_id INT UNSIGNED NOT NULL, INDEX id_idx (id), PRIMARY KEY(user_id, role_id)) ENGINE = INNODB". Failing Query: CREATE TABLE roles_users (user_id INT UNSIGNED NOT NULL, role_id INT UNSIGNED NOT NULL, INDEX id_idx (id), PRIMARY KEY(user_id, role_id)) ENGINE = INNODB I'm creating my tables using Doctrine::createTablesFromModels();

  • css: Cross-browser, reflowing, top-to-bottom, multi-column lists

    - by Sai Emrys
    See http://cssfingerprint.com/about#stats. See also http://stackoverflow.com/questions/933645/multi-column-css-lists. I want a multi-column list that: uses no JS reflows on window size makes as many columns as fit the enclosing element therefore, does not require batching the list into manual column groups works in all browsers works for an arbitrary number of unknown-width (but single-line-height) elements makes each column fit the width of its (dynamic) contents does not create scrollbars or other overflow issues is sorted top to bottom where possible My code is currently: ul.multi, ol.multi { width: 100%; margin: 0; padding: 0; list-style: none; -moz-column-width: 12em; -webkit-column-width: 12em; column-width: 12em; -moz-column-gap: 1em; -webkit-column-gap: 1em; column-gap: 1em; } ul.multi li, ol.multi li { <!--[if IE]> float: left; <![endif]--> width: 20em; margin: 0; padding: 0; } Although this works okay, it has some problems: I have to guess the content width it is right-to-left in IE (though this is acceptable as a graceful degradation mode) it won't work at all in non-IE, non-Moz/Webkit/CSS3 browsers How can this be improved?

  • Jmock mock DAO object

    - by Gandalf StormCrow
    Hi all, I wrote a method that retrieves certain list of strings, given a correct string key. Now when I create a list(the one to be retrieved by method descibed in previous sentence) and create test I can easily get results and test passes successfully. Now on the other hand if I save the content of this list to database in 2 columns, key and value I wrote a class which retrieves this items with method inside it. And when I print it out to console the expected results are correct, now I initialize my DAO from application context where inside its bean it gets session and because of DAO works. Now I'm trying to write a test which will mock the DAO, because I'm running test localy not on the server .. so I told jmock to mock it : private MyDAO myDAO; in the setup() myDAO = context.mock(MyDAO.class); I think I'm mocking it correctly or not, how can I mock this data from database? what is the best way? Is there somewhere good Jmock documentation? on their official site its not very good and clear, you have to know what you seek in order to find it, can't discover something cool in the mean time.

  • iTextSharp - Bug in the table functions?

    - by Matthias
    Hello all together, I try to make a table like this: PdfPTable Table = new PdfPTable(6); PdfPCell Cell = new PdfPCell(new Phrase("a", Font1)); Cell.Rowspan = 2; Cell.Colspan = 2; Table.AddCell(Cell); Cell = new PdfPCell(new Phrase("b", Font1)); Cell.Rowspan = 2; Cell.Colspan = 2; Table.AddCell(Cell); Cell = new PdfPCell(new Phrase("c", Font1)); Cell.Colspan = 2; Table.AddCell(Cell); Cell = new PdfPCell(new Phrase("d", Font1)); Cell.Colspan = 2; Table.AddCell(Cell); That works fine. But changing the number of columns will destory the table. Is it a bug or do I make something wrong? This code destroys the table: PdfPTable Table = new PdfPTable(17); PdfPCell Cell = new PdfPCell(new Phrase("a", Font1)); Cell.Rowspan = 2; Cell.Colspan = 2; Table.AddCell(Cell); Cell = new PdfPCell(new Phrase("b", Font1)); Cell.Rowspan = 2; Cell.Colspan = 10; Table.AddCell(Cell); Cell = new PdfPCell(new Phrase("c", Font1)); Cell.Colspan = 5; Table.AddCell(Cell); Cell = new PdfPCell(new Phrase("d", Font1)); Cell.Colspan = 5; Table.AddCell(Cell); Edit: The table should have this layout: |-------------------------------------------------------| | Cell "a" with | Cell "b" with | Cell "c", colspan = 5 | | colspan = 2 | colspan = 10 |-----------------------| | rowspan = 2 | rowspan = 2 | Cell "d", colspan = 5 | |-------------------------------------------------------| Best regards, Matthias

  • Flex vs. jQuery vs. GWTvs./ Closre vs. Cappuccino vs. plain JS and HTML5?

    - by Laith J
    Hello, I'm creating my first web application and I'm really confused as to what technology to go for. My application needs to look serious (like an application), it doesn't need many colorful graphical interfaces. It only needs a toolbar, a tab bar, a split panel (preferably 3 columns), an easily-formatable text field, and a status bar. It will connect to a MySQL database through PHP (unless I go for GWT). Users will upload files. My evaluation of the options: Flex: Probably the easiest to develop but I'm pretty sure my application is something one would use on an iPad and with Flash's future on the iPad still unsure, I don't want to take the risk, otherwise Flex would've been my choice. jQuery: I've heard a lot about it and a lot of people recommend but I don't know how easy it is to use and how customizable the look of my app is. GWT: The problem with GWT is that it doesn't have many widgets. Another problem is that I'm gonna have to host the files in AppEngine's datastore and transfer them back and forth to a web server that will do operations on them (I need to process them) which adds more traffic and slows the process which worsens the user experience. Closure: It has a nice toolbar and a nice text field. I'm not sure how easy it is to use. Plus, I read an article that makes it sound really bad. Cappuccino: It has a very nice UI and it has a mac feel. I'm planning to give my application a mac feel anyway so this will save me a lot of theming. But if I go for this option I won't be able to make use of HTML5's new features (especially working offline). Plain JS and HTML5: This gives me the most flexibility but it is the hardest to work for. I'm sorry if this is subjective but I really need help with this.

  • WPF Toolkit Charting and IndependentValueBinding, IndependentValuePath

    - by Joel Barsotti
    So I'm having a problem with the charting engine from the WPF toolkit. We haven't moved our data to a proper object model, so the ItemSource is backed with a DataView. First attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValueBinding="{Binding Path=TargetSeries_X}" DependentValueBinding="{Binding Path=TargetSeries_X}" /> This crashes because, I believe, it thinks the bindings are the values to plot or some sort of mismatch. Second attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="{Binding Path=TargetSeries_X}" DependentValuePath="{Binding Path=TargetSeries_X}" /> This crashes during the init step becaue the Path properties aren't backed with dependency properties and therefore cannot be bound. Third attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="targetFooXColumnName" DependentValuePath="targetFooYColumnName" /> Now this works! But I wanted to use the binding so I can switch from using the targetFooXColumnName to the targetFooBarXColumnName. So this solution will cause a whole lot of hacky looking code to switch the Path's manually. Anyway to fix this? Can I use some sort of convertor to get the Binding properties to correctly pull the data from the columns in the DataView? Thanks, Joel

  • Database with "Open Schema" - Good or Bad Idea?

    - by Claudiu
    The co-founder of Reddit gave a presentation on issues they had while scaling to millions of users. A summary is available here. What surprised me is point 3: Instead, they keep a Thing Table and a Data Table. Everything in Reddit is a Thing: users, links, comments, subreddits, awards, etc. Things keep common attribute like up/down votes, a type, and creation date. The Data table has three columns: thing id, key, value. There’s a row for every attribute. There’s a row for title, url, author, spam votes, etc. When they add new features they didn’t have to worry about the database anymore. They didn’t have to add new tables for new things or worry about upgrades. This seems like a terrible idea to me, but it seems to have worked out for Reddit. Is it a good idea in general, though? Or is it a peculiarity of Reddit that happened to work out for them?

  • using text and ntext SQL Datatypes in RPG

    - by David Stratton
    I'll preface this with saying that I'm a .NET developer, and am NOT an RPG developer. I'm working with one of our RPG developers to come up with a solution, so any suggestions you provide will get passed to him. We have a scenario where we want our iSeries to read from a SQL Server database. One of the columns is a TEXT column. IN RPG, there is no equivalent data type to use for this. We've gone back and forth on this, and our current plan is to change course, and have our SQL Server write out a text file, which the iSeries can pick up and parse. This is, however, a last resort option, as the data in the file is sensitive, and we'd like to avoid the additional security overhead. We've already got the SQL Server locked down as tight as possible (one user only has read access to this, and that user is an iSeries user.) We don't want to have to worry about transferring files back and forth. However, at this point, we see no other option. We have no in-house Java developers, and need to do this in RPG. So I'm wondering if there are any RPG developers out there who have faced this situation and have any advice.

  • Hyphen vs Dash : Replace Dash with Hyphen

    - by soldieraman
    Alright so we had a problem recently In reporting services some of the String Columns were appearing as gibberish Chinese characters. On further investigation we found it is the hyphen. Well that's what we though first. On further investigation we found it a dash (or en dash) . Basically the reason this has happened is people copy pasting values into this column from word which converts hyphens into dashes automatically. But if you look at the database they both look the same. Though on the application side you can see the difference. How do I replace the dash with a normal hyphen. If you copy the value in put it in SQL server. A hyphen is gray while a dash is black but they both look exactly the same (i.e not bigger or smaller). Problem is I can't write a REPLACE script then (they are the freakin same) REPLACE ('-' with '-') is there a way special characters like the dash can be identified in SQL server? SQL Server v 2005

  • Update CGridView when a dropdown value changes

    - by Gautam Borad
    I have a CGridView with columns from a table "product" => {'product_id','category_id',...} I have another table "category" => {'category_id','category_name'} category_id is the FK in the product table. Now i want a dropdown list of the category table and on selecting a particular value the CGridView of product should be updated to show only the rows with that category_id. I also need the column filtering/sorting for the CGridView to work (using AJAX). I was able to refresh the CGridView when a value is selected from the dropdown, however i am not able to send the category_id with the 'data' for the CGridView: clientScript-registerScript('search', " $('.cat_dropdown').change(function(){ $.fn.yiiGridView.update('order-grid', { data: $(this).serialize(), }); return false; }); "); The data: $(this).serialize() sends only the values that are present in the filtering text fields of the CGridView. How do i append the category_id with it? If the above method is not the right one, please suggest an alternative method.

  • how to show a large jpg image to the right in jqGrid's edit form ?

    - by cLee
    Is it possible to show a large (i.e. bigger than a thumbnail) jpeg image in the right-hand side of jqGrid's edit form ? Users want to look at a photo while entering data into fields ... they are describing things in the photo. I'm sure all things are possible with jQuery, but I don't know where to begin. thanks ... html: function afterSubmit(r, data, action) { // if session timeout returned: if (r.responseText == "logout") { window.location = '../scripts/logout.php'; } // if an error message is returned: if (r.responseText != "") { $('#submit_errors').html('Alert:'+r.responseText+''); // show div with error message $('#submit_errors').slideDown(); // hide error div after 10 seconds window.setTimeout(function() { $('#submit_errors').slideUp(); }, 10000); return false; // don't remove this! } return true; // don't remove this! } var lastsel; jQuery(document).ready(function(){ var mygrid = jQuery("#mobile_incidents").jqGrid({ url:'list.php?q=e', editurl:'edit.php', datatype: "json", // note: all column names are required even though some columns are hidden colNames:['Rec#','Date','Line','Photo'], colModel:[{ name:'id', index:'id', editable:true, editoptions: {readonly:'readonly'} }, { name:'mobile_discoveryDate', index:'mobile_discoveryDate', sortable:false, editable:true, edittype:'text', formatter:'date', formatoptions:{ srcformat:'Y/m/d', newformat:'m/d/Y' }, editoptions:{ size:12, maxlength:10, dataInit: function(element) { $(element).blur(); $(element).datepicker({dateFormat:'mm/dd/yyyy'}) } } }, { name:'mobile_lineName', index:'mobile_lineName', editable:true, sortable:false}, { name:'mobile_photo_name', index:'mobile_photo_name', editable:false, sortable:false} ], pager: '#mobile_incidents_pager', altRows: false, rowNum:10, rowList:[10,20], imgpath: '../include/images/jqgrid', viewrecords: true, emptyrecords:'No submissions found!', height: 260, sortname: 'id', sortorder: 'desc', gridview: true, scrollrows: true, autowidth: true, rownumbers: false, multiselect: false, subGrid:false, caption: '' }) .navGrid('#mobile_incidents_pager', // params: {add:false, edit:true, del:false, search:false, view:false, refresh:true, alertcap:' to edit:', alerttext:' . . . click on a row to highlight' }, // edit params: {top:50, left:5, editCaption: 'Edit Submission', bSubmit: 'Approve/Save', closeAfterEdit:true, afterSubmit:function(r,data){return afterSubmit(r,data,'edit');} }, {}, // add params {}, // delete params // search params: {multipleSearch: false}, // view params: {top: 150, left: 5, caption: 'View Mobile Rail Submission'} ); });

  • Character set issues with Oracle Gateways, SQL Server, and Application Express

    - by Brian Deterling
    I am migrating data from a Oracle on VMS that accesses data on SQL Server using heterogeneous services (over ODBC) to Oracle on AIX accessing the SQL Server via Oracle Gateways (dg4msql). The Oracle VMS database used the WE8ISO8859P1 character set. The AIX database uses WE8MSWIN1252. The SQL Server database uses "Latin1-General, case-insensitive, accent-sensitive, kanatype-insensitive, width-insensitive for Unicode Data, SQL Server Sort Order 52 on Code Page 1252 for non-Unicode Data" according to sp_helpsort. The SQL Server databases uses nchar/nvarchar or all string columns. In Application Express, extra characters are appearing in some cases, for example 123 shows up as %001%002%003. In sqlplus, things look ok but if I use Oracle functions like initcap, I see what appear as spaces between each letter of a string when I query the sql server database (using a database link). This did not occur under the old configuration. I'm assuming the issue is that an nchar has extra bytes in it and the character set in Oracle can't convert it. It appears that the ODBC solution didn't support nchars so must have just cast them back to char and they showed up ok. I only need to view the sql server data so I'm open to any solution such as casting, but I haven't found anything that works. Any ideas on how to deal with this? Should I be using a different character set in Oracle and if so, does that apply to all schemas since I only care about one of them.

  • Excel Prorated SUMIF

    - by Pete Michaud
    I have a worksheet with 2 columns, one is a dollar amount, and the other is a day of the month (1 through 31) that the dollar amount is due by (the dollars are income streams). So, I use the following formula to SUM all the income streams due on or before a certain day: =SUMIF(C5:C14, "<="&$B$42,B5:B14) Column C is the due day B42 is the cell in which I input the day to compare to like "15" for "total of all income due on or before the 15th" - the idea is to have a sum of all income received for the period. Column B is the dollar amount for each income stream. My question is: Some of the income streams don't have a day next to them (the day cell in column C is blank). That means that that income stream doesn't come in as a check or a chunk on a certain date, it trickles in roughly evenly through out the month. So if the amount for the income stream is $10,000 and the day is 15 in a 30 day month, then I should add $5,000 to the total. That would be something like: =SUMIF(C5:C14, "",???) So where the due date is blank, select ???. ??? isn't just the number, it's the number*(given_day/total_days_in_month). So I think what I need for an accurate total is: =SUMIF(C5:C14, "<="&$B$42,B5:B14) + SUMIF(C5:C14, "",???) But I'm not sure how to write that exactly.

  • Implementing Naïve Bayes algorithm in Java - Need some guidance

    - by techventure
    hello stackflow people As a School assignment i'm required to implement Naïve Bayes algorithm which i am intending to do in Java. In trying to understand how its done, i've read the book "Data Mining - Practical Machine Learning Tools and Techniques" which has a section on this topic but am still unsure on some primary points that are blocking my progress. Since i'm seeking guidance not solution in here, i'll tell you guys what i thinking in my head, what i think is the correct approach and in return ask for correction/guidance which will very much be appreciated. please note that i am an absolute beginner on Naïve Bayes algorithm, Data mining and in general programming so you might see stupid comments/calculations below: The training data set i'm given has 4 attributes/features that are numeric and normalized(in range[0 1]) using Weka (no missing values)and one nominal class(yes/no) 1) The data coming from a csv file is numeric HENCE * Given the attributes are numeric i use PDF (probability density function) formula. + To calculate the PDF in java i first separate the attributes based on whether they're in class yes or class no and hold them into different array (array class yes and array class no) + Then calculate the mean(sum of the values in row / number of values in that row) and standard divination for each of the 4 attributes (columns) of each class + Now to find PDF of a given value(n) i do (n-mean)^2/(2*SD^2), + Then to find P( yes | E) and P( no | E) i multiply the PDF value of all 4 given attributes and compare which is larger, which indicates the class it belongs to In temrs of Java, i'm using ArrayList of ArrayList and Double to store the attribute values. lastly i'm unsure how to to get new data? Should i ask for input file (like csv) or command prompt and ask for 4 values? I'll stop here for now (do have more questions) but I'm worried this won't get any responses given how long its got. I will really appreciate for those that give their time reading my problems and comment.

  • How do I eliminate Error 3002?

    - by Andrew
    Say I have the following table definitions in SQL Server 2008: CREATE TABLE Person (PersonId INT IDENTITY NOT NULL PRIMARY KEY, Name VARCHAR(50) NOT NULL, ManyMoreIrrelevantColumns VARCHAR(MAX) NOT NULL) CREATE TABLE Model (ModelId INT IDENTITY NOT NULL PRIMARY KEY, ModelName VARCHAR(50) NOT NULL, Description VARCHAR(200) NULL) CREATE TABLE ModelScore (ModelId INT NOT NULL REFERENCES Model (ModelId), Score INT NOT NULL, Definition VARCHAR(100) NULL, PRIMARY KEY (ModelId, Score)) CREATE TABLE PersonModelScore (PersonId INT NOT NULL REFERENCES Person (PersonId), ModelId INT NOT NULL, Score INT NOT NULL, PRIMARY KEY (PersonId, ModelId), FOREIGN KEY (ModelId, Score) REFERENCES ModelScore (ModelId, Score)) The idea here is that each Person may have only one ModelScore per Model, but each Person may have a score for any number of defined Models. As far as I can tell, this SQL should enforce these constraints naturally. The ModelScore has a particular "meaning," which is contained in the Definition. Nothing earth-shattering there. Now, I try translating this into Entity Framework using the designer. After updating the model from the database and doing some editing, I have a Person object, a Model object, and a ModelScore object. PersonModelScore, being a join table, is not an object but rather is included as an association with some other name (let's say ModelScorePersonAssociation). The mapping details for the association are as follows: - Association - Maps to PersonModelScore - ModelScore ModelId : Int32 <=> ModelId : int Score : Int32 <=> Score : int - Person PersonId : Int32 <=> PersonId : int On the right-hand side, the ModelId and PersonId values have primary key symbols, but the Score value does not. Upon compilation, I get: Error 3002: Problem in Mapping Fragment starting at line 5190: Potential runtime violation of table PersonModelScore's keys (PersonModelScore.ModelId, PersonModelScore.PersonId): Columns (PersonModelScore.PersonId, PersonModelScore.ModelId) are mapped to EntitySet ModelScorePersonAssociation's properties (ModelScorePersonAssociation.Person.PersonId, ModelScorePersonAssociation.ModelScore.ModelId) on the conceptual side but they do not form the EntitySet's key properties (ModelScorePersonAssociation.ModelScore.ModelId, ModelScorePersonAssociation.ModelScore.Score, ModelScorePersonAssociation.Person.PersonId). What have I done wrong in the designer or otherwise, and how can I fix the error? Many thanks!

  • Change find method in database search so that it isn't case sensitive in Rails app

    - by Ryan
    Hello, I am learning Rails and have created a work-in-progress app that does one-word searches on a database of shortcut keys for various programs (http://keyboardcuts.heroku.com/shortcuts/home). The search method in the Shortcut model is the following: def self.search(search) search_condition = "%" + search + "%" find(:all, :conditions => ['action LIKE ? OR application LIKE ?', search_condition, search_condition]) end ...where 'action' and 'application' are columns in a SQLite table. (source: https://we.riseup.net/rails/simple-search-tutorial) For some reason, the search seems to be case sensitive (you can see this by searching 'Paste' vs. 'paste'). Can anyone help me figure out why and what I can do to make it not case sensitive? If not, can you at least point me in the right direction? Database creation: I first copied shortcuts from various website into Excel and saved it as a CSV. Then I migrated the database and filled it with the data using db:seed and a small script I wrote (I viewed the database and it looked fine). To get the SQLite database to the server, I used Taps as outline by the Heroku website (http://blog.heroku.com/archives/2009/3/18/push_and_pull_databases_to_and_from_heroku/). I am using Ubuntu. Please let me know if you need more information. Thanks in advance for you help, very much appreciated! Ryan

  • JPA : many-to-many - only one foreign key in the association table

    - by Julien
    Hi, I mapped two classes in a ManyToMany association with these annotations : @Entity @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) public abstract class TechnicalItem extends GenericBusinessObject implements Resumable{ @SequenceGenerator(name="TECHNICAL_ITEM_ID_GEN", sequenceName="TECHNICAL_ITEM_ID_SEQ") @Id @Column(name = "\"ID\"", nullable = false) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "TECHNICAL_ITEM_ID_GEN") private int id; @ManyToMany(mappedBy = "referencePerformanceItems", fetch=FetchType.LAZY) private List testingRates; } @Entity @DiscriminatorValue("T") public class TestingRate extends Rate { @ManyToMany(fetch=FetchType.LAZY) @JoinTable(name="ecc.\"TESTING_RATE_TECHNICAL_ITEM\"", joinColumns = {@JoinColumn(name = "\"TESTING_RATE_ID\"")}, inverseJoinColumns = {@JoinColumn(name = "\"TECHNICAL_ITEM_ID\"")}) //@ManyToMany(mappedBy = "testingRates", fetch=FetchType.LAZY) private List referencePerformanceItems; } The sql generated for the association table creation is : create table ecc."TESTING_RATE_TECHNICAL_ITEM" ( "TESTING_RATE_ID" int4 not null, "TECHNICAL_ITEM_ID" int4 not null ); alter table ecc."TESTING_RATE_TECHNICAL_ITEM" add constraint FKC5D64DF6A2FE2698 foreign key ("TESTING_RATE_ID") references ecc."RATE"; There is no mention of the second foreign key "TECHNICAL_ITEM_ID" (the second part of the composite foreign key which should be in the association table). Is it a normal behaviour ? What should I do in the mapping if I want my 2 columns are 2 foreign keys referencing the primary keys of my 2 concerned tables. I use a PostGreSQL database and Hibernate as JPA provider. Thanks, Julien

  • Filter rows on the basis of "First Name" + "Last Name" in SQL

    - by Raghav Khunger
    Hi, I have a user table in my database which contains two columns FirstName and LastName. Now in my front end there is a textbox to filter out the users from this table. Let's suppose I am taking that input from the front end in the form of a input parameter "@SEARCHKEYWORD". I have created a sample below: DECLARE @Test TABLE ([ID] INT IDENTITY, [FNAME] NVARCHAR(100), [LNAME] NVARCHAR(100) ) INSERT INTO @Test( FNAME, LNAME ) SELECT 'John','Resig' UNION ALL SELECT 'Dave','Ward' UNION ALL SELECT 'Peter','Smith' UNION ALL SELECT 'Dave','Smith' UNION ALL SELECT 'Girija','Acharya' UNION ALL SELECT 'Devendra', 'Gujel' UNION ALL SELECT 'Arjit', 'Gupta' DECLARE @SEARCHKEYWORD NVARCHAR(100) SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD i.e. so far I have thought of this query to filter out the rows but it is not giving the desired results: SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD Here are the desired outputs which I needed for the inputs mentioned below: --WHEN @SEARCHKEYWORD='John Resig' --Desired OUTPUT: the row which contains 'John','Resig' --WHEN @SEARCHKEYWORD='Ac' --Desired OUTPUT: the row which contains 'Girija','Acharya' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith' --WHEN @SEARCHKEYWORD='g' --Desired OUTPUT: the row which contains 'Devendra', 'Gujel' and 'Arjit', 'Gupta' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith'
