  • Hibernate custom join clause on association

    - by myso
    I would like to associate 2 entities using hibernate annotations with a custom join clause. The clause is on the usual FK/PK equality, but also where the FK is null. In SQL this would be something like: join b on a.id = b.a_id or b.a_id is null From what I have read I should use the @WhereJoinTable annotation on the owner entity, but I'm puzzled about how I specify this condition...especially the first part of it - referring to the joining entity's id. Does anyone have an example?

  • How to access xmlParserCtxt structure from within xmlSAXHandler callbacks?

    - by Lux In Tenebris
    I'm parsing (X)HTML pages content with libxml using the following call: htmlDocPtr doc = htmlSAXParseDoc(content, NULL, &html_handler, NULL); But for debugging purposes I need to analyze some of the current node properties in the start/end element callbacks. I know that the fourth argument of htmlSAXParseDoc can be used to pass any user defined data to the callbacks, but I don't have a pointer to xmlParserCtxt.

  • What makes a Winform position initially stale?

    - by msorens
    The code below demonstrates a very simple problem; I am hoping that I am just missing a setting that someone might be able to reveal. Goal (1) Launch main winform (MainForm). (2) Press button to display secondary winform (ShadowForm) that is semi-transparent and should exactly overlay MainForm. What Actually Happens Scenario 1: Launch main winform then press button: ShadowForm displays with correct size but incorrect location, lower and to the right (as if it was cascaded). Press button to close ShadowForm again. Press button once more to reopen ShadowForm and now it is in the correct position, covering MainForm. Scenario 2: Launch main winform, move it around, then press button: ShadowForm displays with correct size but incorrect location (where the MainForm was before moving it). Press button to close; press again to reopen and now ShadowForm is in the correct position. using System; using System.Windows.Forms; namespace LocationTest { static class Program { static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new MainForm()); } } public class MainForm : Form { ShadowForm shadowForm = new ShadowForm(); Button button1 = new Button(); System.ComponentModel.IContainer components = null; public MainForm() { this.SuspendLayout(); this.button1.Location = new System.Drawing.Point(102, 44); this.button1.Size = new System.Drawing.Size(75, 23); this.button1.Text = "button1"; this.button1.Click += new System.EventHandler(this.button1_Click); this.ClientSize = new System.Drawing.Size(292, 266); this.Controls.Add(this.button1); this.ResumeLayout(false); } private void button1_Click(object sender, EventArgs e) { if (shadowForm.Visible) { shadowForm.Hide(); } else { shadowForm.Size = Size; // this always works shadowForm.Location = Location; // this fails first time, but works second time! shadowForm.Show(); } } protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } } public class ShadowForm : Form { private System.ComponentModel.IContainer components = null; public ShadowForm() { this.SuspendLayout(); this.BackColor = System.Drawing.Color.Black; this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; this.Opacity = 0.5; this.Click += new System.EventHandler(this.ShadowForm_Click); this.ResumeLayout(false); } private void ShadowForm_Click(object sender, EventArgs e) { Hide(); } protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); } } }

  • Update multiple table column values using single query

    - by Dave Jarvis
    How would you update data in multiple tables using a single query? In MySQL it would be: UPDATE party p LEFT JOIN party_name n ON p.party_id = n.party_id LEFT JOIN party_details d ON p.party_id = d.party_id LEFT JOIN incident_participant ip ON ip.party_id = p.party_id LEFT JOIN incident i ON ip.incident_id = i.incident_id SET p.employee_id = NULL, c.em_address = '[email protected]', c.ad_postal = 'x', n.first_name = 'x', n.last_name = 'x' WHERE i.confidential_dt IS NOT NULL What is the equivalent SQL statement using Oracle 11g? (Is ANSI SQL possible?) Thank you!

  • Function returning MYSQL_ROW

    - by Gabe
    I'm working on a system using lots of MySQL queries and I'm running into some memory problems I'm pretty sure have to do with me not handling pointers right... Basically, I've got something like this: MYSQL_ROW function1() { string query="SELECT * FROM table limit 1;"; MYSQL_ROW return_row; mysql_init(&connection); // "connection" is a global variable if (mysql_real_connect(&connection,HOST,USER,PASS,DB,0,NULL,0)){ if (mysql_query(&connection,query.c_str())) cout << "Error: " << mysql_error(&connection); else{ resp = mysql_store_result(&connection); //"resp" is also global if (resp) return_row = mysql_fetch_row(resp); mysql_free_result(resp); } mysql_close(&connection); }else{ cout << "connection failed\n"; if (mysql_errno(&connection)) cout << "Error: " << mysql_errno(&connection) << " " << mysql_error(&connection); } return return_row; } And function2(): MYSQL_ROW function2(MYSQL_ROW row) { string query = "select * from table2 where code = '" + string(row[2]) + "'"; MYSQL_ROW retorno; mysql_init(&connection); if (mysql_real_connect(&connection,HOST,USER,PASS,DB,0,NULL,0)){ if (mysql_query(&connection,query.c_str())) cout << "Error: " << mysql_error(&conexao); else{ // My "debugging" shows me at this point `row[2]` is already fubar resp = mysql_store_result(&connection); if (resp) return_row = mysql_fetch_row(resp); mysql_free_result(resp); } mysql_close(&connection); }else{ cout << "connection failed\n"; if (mysql_errno(&connection)) cout << "Error : " << mysql_errno(&connection) << " " << mysql_error(&connection); } return return_row; } And main() is an infinite loop basically like this: int main( int argc, char* args[] ){ MYSQL_ROW row = NULL; while (1) { row = function1(); if(row != NULL) function2(row); } } (variable and function names have been generalized to protect the innocent) But after the 3rd or 4th call to function2, that only uses row for reading, row starts losing its value coming to a segfault error... Anyone's got any ideas why? I'm not sure the amount of global variables in this code is any good, but I didn't design it and only got until tomorrow to fix and finish it, so workarounds are welcome! Thanks!

  • Javascript - proper getAttributeNode on IE6+

    - by Darrow
    I have a regular input box (no onchange attribute). <input type="text" id="bar" name="bar" /> For some reason, IE6+ does returns [object], while FF and Chrome returns null. if ((elem.getAttributeNode('onchange')) != null) elem.onchange(); I did also try as: if (typeof(elem.onchange) !== 'undefined') elem.onchange(); What would be the proper cross-browser way to check if the element has the attribute? Thanks

  • SAX parser does not resolve filename

    - by phantom-99w
    Another day, another strange error with SAX, Java, and friends. I need to iterate over a list of File objects and pass them to a SAX parser. However, the parser fails because of an IOException. However, the various File object methods confirm that the file does indeed exist. The output which I get: 11:53:57.838 [MainThread] DEBUG DefaultReactionFinder - C:\project\trunk\application\config\reactions\TestReactions.xml 11:53:57.841 [MainThread] ERROR DefaultReactionFinder - C:\project\trunk\application\config\reactions\null (The system cannot find the file specified) So the problem is obviously that null in the second line. I've tried nearly all variations of passing the file as a parameter to the parser, including as a String (both from getAbsolutePath() and entered by hand), as a URI and, even more weirdly, as a FileInputStream (for this I get the same error, except that the entire relative path gets reported as null, so C:\project\trunk\null). All that I can think of is that the SAXParserFactory is incorrectly configured. I have no idea what is wrong, though. Here is the code concerned: SAXParserFactory factory = SAXParserFactory.newInstance(); factory.setValidating(true); try { parser = factory.newSAXParser(); } catch (ParserConfigurationException e) { throw new InstantiationException("Error configuring an XML parser. Given error message: \"" + e.getMessage() + "\"."); } catch (SAXException e) { throw new InstantiationException("Error creating a SAX parser. Given error message: \"" + e.getMessage() + "\"."); } ... for (File f : fileLister.getFileList()) { logger.debug(f.getAbsolutePath()); try { parser.parse(f, new ReactionHandler(input)); //FileInputStream fs = new FileInputStream(f); //parser.parse(fs, new ReactionHandler(input)); //fs.close(); } catch (IOException e) { logger.error(e.getMessage()); throw new ReactionNotFoundException("An error occurred processing file \"" + f + "\"."); } ... } I have made no special provisions to provide a custom SAX parser implementation: I use the system default. Any help would be greatly appreciated!

  • Are Conditional subquery

    - by Tobias Schulte
    I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out?

  • How can I validate two or more fields in combination?

    - by DR
    I'm using JPA 2.0/Hibernate validation to validate my models. I now have a situation where the combination of two fields has to be validated: public class MyModel { public Integer getValue1() { //... } public String getValue2() { //... } } The model is invalid if both getValue1() and getValue2() are null and valid otherwise. How can I perform this kind of validation with JPA 2.0/Hibernate? With a simple @NotNull annotation both getters must be non-null to pass validation.

  • Error:A generic error occurred in GDI+

    - by sanfra1983
    Hi, I created a web project on the server, and when I upload an image shows me the error Error: A generic error occurred in GDI +. I have read many links on the net that talk about this issue, and although I made the changes, nothing went wrong. I was thinking if the case is not an issue of permissions to folders. In fact I have two folders one inside the other.

In order to accomplish that, i'm using the following daemonize() code: static void daemonize(void) { pid_t pid, sid; /* already a daemon */ if ( getppid() == 1 ) return; /* Fork off the parent process */ pid = fork(); if (pid < 0) { exit(EXIT_FAILURE); } /* If we got a good PID, then we can exit the parent process. */ if (pid > 0) { exit(EXIT_SUCCESS); } /* At this point we are executing as the child process */ /* Change the file mode mask */ umask(0); /* Create a new SID for the child process */ sid = setsid(); if (sid < 0) { exit(EXIT_FAILURE); } /* Change the current working directory. This prevents the current directory from being locked; hence not being able to remove it. */ if ((chdir("/")) < 0) { exit(EXIT_FAILURE); } /* Redirect standard files to /dev/null */ freopen( "/dev/null", "r", stdin); freopen( "/dev/null", "w", stdout); freopen( "/dev/null", "w", stderr); } int main( int argc, char *argv[] ) { daemonize(); /* Now we are a daemon -- do the work for which we were paid */ return 0; } I have a strange side effect when testing the server on Debian (Ubuntu). The accept() function always fail to accept connections, the pid returned is -1 I have no idea what causing this, since in RedHat & CentOS it works well. When i remove the call to daemonize(), everything works well on Debian, when i add it back, same accept() error reproduce. I've been monitring the /proc//fd, everything looks good. Something in the daemonize() and the Debian release just doesn't seem to work. (Debian GNU/Linux 5.0, Linux 2.6.26-2-286 #1 SMP) Any idea what causing this? Thank you

  • Setting the first two bytes of a block of memory

    - by idealistikz
    Suppose I have a block of memory as such: void *block = malloc(sizeof(void *) + size); How do I set the first two bytes of the block as NULL or have it point somewhere? I do not want to simply assign 'block' to NULL or to another pointer because I want to access the rest of the memory I malloc'ed.
