  • Serialization of Queue type not working

    - by Soham
    Consider this piece of code: private Queue Date=new Queue(); //other declarations public DateTime _Date { get { return (DateTime)Date.Peek();} set { Date.Enqueue(value); } } //other properties and stuff.... public void UpdatePosition(...) { //other code IFormatter formatter = new BinaryFormatter(); Stream Datestream = new MemoryStream(); formatter.Serialize(Datestream, Date); byte[] Datebin = new byte[2048]; Datestream.Read(Datebin,0,2048); //Debug-Bug Console.WriteLine(Convert.ToString(this._Date)); Console.WriteLine(BitConverter.ToString(Datebin, 0, 3)); //other code } The output of the first WriteLine is perfect. I.e to check if really the Queue is initialised or not. It is. The right variables are stored etc. (I inserted a value in that Queue, that part of the code is not shown.) But the second WriteLine is not giving the right expected answer: It serializes the entire Queue to 00-00-00.

  • Which method of 'clearfix' is best?

    - by Pickledegg
    I have the age old problem of a div wrapping a 2 column layout. My sidebar is floated so my container div fails to wrap the content & sidebar. <div id="container"> <div id="content"> </div> <div id="sidebar"> </div> </div> There seem to be numerous methods of fixing the clear bug in FF: <br clear="all"/> overflow:auto overflow:hidden etc. But in my situation, the only one that seems to work correctly is the <br clear="all"/> solution, which is a little bit scruffy. overflow:auto gives me nasty scrollbars, and overflow:hidden must surely have side effects. Also, apparently IE7 is supposed to not suffer from this problem due to its incorrect behaviour, but again, in my situation its suffering the same as FF. Whats the most reliable/best practice method currently available to us?

  • Segmentation fault on returning from main (very short and simple code, no arrays or pointers)

    - by Gábor Kovács
    I've been wondering why the following trivial code produces a segmentation fault when returning from main(): //Produces "Error while dumping state (probably corrupted stack); Segmentation fault" #include <iostream> #include <fstream> #include <vector> using namespace std; class Test { vector<int> numbers; }; int main() { Test a; ifstream infile; cout << "Last statement..." << endl; // this gets executed return 0; } Interestingly, 1) if only one of the two variables is declared, I don't get the error, 2) if I declare a vector variable instead of an object with a vector member, everything's fine, 3) if I declare an ofstream instead of an ifstream, again, everything works fine. Something appears to be wrong with this specific combination... Could this be a compiler bug? I use gcc version 3.4.4 with cygwin. Thanks for the tips in advance. Gábor

  • UITableViewRowAnimationBottom doesn't work for last row

    - by GendoIkari
    I've come across a very similar question here: Inserting row to end of table with UITableViewRowAnimationBottom doesn't animate., though no answers have been given. His code was also a little different than mine. I have an extremely simple example, built from the Navigation application template. NSMutableArray *items; - (void)viewDidLoad { [super viewDidLoad]; items = [[NSMutableArray array] retain]; self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addItem)] autorelease]; } - (void)addItem{ [items insertObject:@"new" atIndex:0]; [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:0 inSection:0]] withRowAnimation:UITableViewRowAnimationBottom]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return items.count; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [items objectAtIndex:indexPath.row]; return cell; } - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { [items removeObjectAtIndex:indexPath.row]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationBottom]; } } The problem is, when I either insert or delete the very last row in the table, the animation doesn't work at all; the row just appears or disappears instantly. This only happens with UITableViewRowAnimationBottom, but that's the animation that makes the most sense for creating or deleting table cells in this way. Is this a bug in Apple's framework? Or does it do this on purpose? Would it make sense to add an extra cell to the count, and then setup this cell so that it looks like it's not there at all, just to get around this behavior?

  • How to catch unintentional function interpositioning?

    - by SiegeX
    Reading through my book Expert C Programming, I came across the chapter on function interpositioning and how it can lead to some serious hard to find bugs if done unintentionally. The example given in the book is the following: my_source.c mktemp() { ... } main() { mktemp(); getwd(); } libc mktemp(){ ... } getwd(){ ...; mktemp(); ... } According to the book, what happens in main() is that mktemp() (a standard C library function) is interposed by the implementation in my_source.c. Although having main() call my implementation of mktemp() is intended behavior, having getwd() (another C library function) also call my implementation of mktemp() is not. Apparently, this example was a real life bug that existed in SunOS 4.0.3's version of lpr. The book goes on to explain the fix was to add the keyword static to the definition of mktemp() in my_source.c; although changing the name altogether should have fixed this problem as well. This chapter leaves me with some unresolved questions that I hope you guys could answer: Does GCC have a way to warn about function interposition? We certainly don't ever intend on this happening and I'd like to know about it if it does. Should our software group adopt the practice of putting the keyword static in front of all functions that we don't want to be exposed? Can interposition happen with functions introduced by static libraries? Thanks for the help. EDIT I should note that my question is not just aimed at interposing over standard C library functions, but also functions contained in other libraries, perhaps 3rd party, perhaps ones created in-house. Essentially, I want to catch any instance of interpositioning regardless of where the interposed function resides.

  • FluentNHibernate: multiple one-to-many relationships between the same entities.

    - by Venemo
    Hi, I'm working on a bug tracking application. There are tickets, and each ticket has an opener user and an assigned user. So, basically, I have two entities, which have two many-to-one relationships with each other. Their schematic is this: User: public class User { public virtual int Id { get; private set; } ... public virtual IList<Ticket> OpenedTickets { get; set; } public virtual IList<Ticket> AssignedTickets { get; set; } } Ticket: public class Ticket { public virtual int Id { get; protected set; } ... [Required] public virtual User OpenerUser { get; set; } public virtual User AssignedUser { get; set; } } I use FluentNHibernate's auto mapping feature. The problem is, that no matter whether relationship I set, on the side of the User, both collections always contain the same data. I guess Fluent can't tell which end of which relationship belongs to where. I googled around but haven't found anything useful. Could anyone help me, please?

  • "date_part('epoch', now() at time zone 'UTC')" not the same time as "now() at time zone 'UTC'" in po

    - by sirlark
    I'm writing a web based front end to a database (PHP/Postgresql) in which I need to store various dates/times. The times are meant to be always be entered on the client side in the local time, and displayed in the local time too. For storage purposes, I store all dates/times as integers (UNIX timestamps) and normalised to UTC. One particular field has a restriction that the timestamp filled in is not allowed to be in the future, so I tried this with a database constraint... CONSTRAINT not_future CHECK (timestamp-300 <= date_part('epoch', now() at time zone 'UTC')) The -300 is to give 5 minutes leeway in case of slightly desynchronised times between browser and server. The problem is, this constraint always fails when submitting the current time. I've done testing, and found the following. In PostgreSQL client: SELECT now() -- returns correct local time SELECT date_part('epoch', now()) -- returns a unix timestamp at UTC (tested by feeding the value into the date function in PHP correcting for its compensation to my time zone) SELECT date_part('epoch', now() at time zone 'UTC') -- returns a unix timestamp at two time zone offsets west, e.g. I am at GMT+2, I get a GMT-2 timestamp. I've figured out obviously that dropping the "at time zone 'UTC'" will solve my problem, but my question is if 'epoch' is meant to return a unix timestamp which AFAIK is always meant to be in UTC, why would the 'epoch' of a time already in UTC be corrected? Is this a bug, or I am I missing something about the defined/normal behaviour here.

  • Has subversion lost some of my revisions in a branch?

    - by BombDefused
    I've been working on my project using a subversion branch. I've used the branching feature few times before without issue, until today. I've come to merge back into the trunk, and noticed that not everything from my branch was there. I go back to my project folder which I've been committing to the branch and look at the log messages using TortoiseSVN (the command line basic log command shows the same). See the attached image. The revision numbers go up incrementally, until revision 303 (the last trunk revision was 299). Then there are numbers missing. The latest commit, about half an hour ago was 316, but it doesn't show up in the log for the branch. Trying to commit the files again doesn't do anything. I am the only person committing to this repository at present. The missing revisions do not show up in the log for the trunk project. What's going on here. Is this a bug or am I doing something wrong? Update - the revisions do show in the repo browser (Thanks Antonio Perez), but I don't understand why they are not being included with the merge?

  • Should I have one dll or multiple for Business Logic?

    - by Brian
    In my situation, my company services many types of customers. Almost every customer requires their own Business Logic. Of course, there will be a base layer that all business logic should inherit from. However, I'm going back and forth on architecting this--either in one dll for all customers or one dll for each. My biggest point of contention deals with upgrading the software. We have about 12 data entry personnel that work with 20 companies and it's critical that they have little down time. My concern is that if I deploy everything in one dll, I could introduce a bug in company A's logic while only intending to update Company B's logic. I believe I could reduce the risk if each company's logic had their own dll, so then, I could deploy Company B's update w/o harming Company A's. -- I will be the only one supporting this. That said, this also seems like a nightmare to manage 20 different .dll's -- that's for the BLL alone. I also need to create a View layer and ViewModel layer. So, potentially, I could have 20 (companies) * 3 (layers) which would equate to 60 .dll's. Thank You.

  • DBD::CSV: Problem with userdefined functions

    - by sid_com
    From the SQL::Statement::Functions documentation: Creating User-Defined Functions ... More complex functions can make use of a number of arguments always passed to functions automatically.

  • Javascript style variables with "-" in their name aren't able to be changed?

    - by William
    Okay, so this bug has cost me quite a bit of time and embarrassment. It seems that any style variable with a - in it's name can't be modified by javascript. As seen here: <!DOCTYPE html> <html lang="en"> <head> <title>Class Test</title> <meta charset="utf-8" /> <style> body { text-align: center; background-color: #ffffff;} #box { position: absolute; left: 610px; top: 80px; height: 50px; width: 50px; background-color: #ff0000; color: #000000;} </style> <script type="text/javascript"> var box = 0; </script> </head> <body> <div id="box" ></div> <script type="text/javascript"> box = document.getElementById('box'); box.style.background-color = "#0000ff"; </script> </body> </html> The box in said example will just remain red. So how do I change a style variable with a - in it's name?

  • "Ghost" values in PHP/Smarty.

    - by Kyle Sevenoaks
    I've been working on a site for a while changing the layout and skin of a webshop checkout process. I've noticed that if you go all the way through the process until the last page, then click the link to go back to the view products page, the delivery method price displays underneath the navigation buttons, until you refresh and it goes away again. I've downloaded both sourced from the browser (Chrome, but this bug applies to all browsers) and used a file difference tool to display the differences, the result being only: < error.html vs > normal.html 34c34 < <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272181" rel="Stylesheet" type="text/css"/> --- > <link href="gzip.php?file=167842c1496093fbcd391b41cf7b03da.css&time=1272272348" rel="Stylesheet" type="text/css"/> Which is just the way it zips up the CSS stylesheets. (afaik) Has anyone ever encountered such a problem, or anything similar? Normal: Error: I can't even hazard a guess as to what is causing this, at all. I've searched over Google for anything and come up with nothing. What could be causing this? The site in question is Euroworker.no. HTML @ Pastebin. Smarty snippet: {if !$CANONICAL} {canonical}{self}{/canonical} {/if} <link rel="canonical" href="{$CANONICAL}" /> <!-- Css includes --> {includeCss file="frontend/Frontend.css"} {includeCss file="backend/stat.css"} {if {isRTL}} {includeCss file="frontend/FrontendRTL.css"} {/if} {compiledCss glue=true nameMethod=hash} <!--[if lt IE 8]> <link href="stylesheet/frontend/FrontendIE.css" rel="Stylesheet" type="text/css"/> {if $ieCss} <link href="{$ieCss}" rel="Stylesheet" type="text/css"/> {/if} <![endif]--> Thanks.

  • Tab Content Does Not Refresh After First Click of Like Button

    - by Adam
    I've implemented a very simple "like guard" for a facebook tab, and am running into an issue with my test users. Multiple testers are reporting that when they open a tab and click the "like" button, they do not always get a page refresh (so the like guard does not disappear until they do a manual reload). This is using facebook's like button at the top of the page, not one I've coded up myself. As a sanity check, I enabled some simple logging on my server and have been able to recreate the issue - I hit "like" or "unlike" but there seems to be no request made to my index.php page, so definitely no refresh happening. I'm aware of this old bug https://developers.facebook.com/bugs/228778937218386 but this one seems different. For starters, after the first click of the "like" button, if I just continue clicking unlike/like/.... then the refresh happens automatically, as expected. What's especially weird is that if I reload the page after the first failed refresh, the refreshes start working again as expected, ie the first update to my like status triggers a page refresh. Some possibly (?) relevant info: My Tab is part of a test page, and is unpublished I am only using http hosting for the tab content, since my https isn't set up yet So far I've just tested with other admins - so maybe user role affects this? Curious to see if anyone has run into this issue before.

  • LicenseChecker checkAccess leaks ServiceConnection

    - by Bill The Ape
    I am receiving this exception in LogCat every time I press the Back button in my app: Activity has leaked ServiceConnection com.android.vending.licensing.LicenseChecker@471cc039 that was originally bound here The code responsible for this leak in onCreate() is: mLicenseCheckerCallback = new MyLicenseCheckerCallback(); mChecker.checkAccess(mLicenseCheckerCallback); How do I get rid of this leak? I tried not assigning MyLicenseCheckerCallback to a member, thinking perhaps when the activity goes onPause() the reference to the callback is responsible for the leak: mChecker.checkAccess(new MyLicenseCheckerCallback()); But that didn't get rid of the leak. Update: Thanks to @zapl's comment below, I looked at Google's LicenseChecker.java: /** Unbinds service if necessary and removes reference to it. */ private void cleanupService() { if (mService != null) { try { mContext.unbindService(this); } catch (IllegalArgumentException e) { // Somehow we've already been unbound. This is a non-fatal error. Log.e(TAG, "Unable to unbind from licensing service (already unbound)"); } mService = null; } } At first I thought that I may be neglecting to call it, but I double-checked and I am calling mChecker.onDestroy(); in my activity's onDestroy(). I also checked onDestroy() in LicenseChecker.java and it is calling unbindService: /** * Inform the library that the context is about to be destroyed, so that * any open connections can be cleaned up. * <p> * Failure to call this method can result in a crash under certain * circumstances, such as during screen rotation if an Activity requests * the license check or when the user exits the application. */ public synchronized void onDestroy() { cleanupService(); mHandler.getLooper().quit(); } So, what is really going on? Is this a bug in LVL?

  • SQL developer here -- Nesting with select * finicky in Oracle 10g?

    - by John Sullivan
    I am writing a simple diagnostic query I will execute in my Oracle 10g scratchpad. I am trying to do this as part of a step to build the query. In the SQL Scratchpad for Oracle 10g Enterprise Manager Console, this statement runs fine. SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ' If I try to wrap that up in Select * from () tb2 I get an error, "ORA-00918: Column Ambiguously Defined". I didn't think that could ever happen with this kind of statement so I am a bit confused. select * from (SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ') tb2 You should always be able to select * from the result set of another select * statement using this structure as far as I'm aware... right? Is Oracle/10g/the scratchpad trying to force me to accept a certain syntactic structure to prevent excessive nesting? Is this a bug in scratchpad or something about how oracle works?

  • A member variable's hashCode() value is different

    - by Jacques René Mesrine
    There's a piece of code that looks like this. The problem is that during bootup, 2 initialization takes place. (1) Some method does a reflection on ForumRepository & performs a newInstance() purely to invoke #setCacheEngine. (2) Another method following that invokes #start(). I am noticing that the hashCode of the #cache member variable is different sometimes in some weird scenarios. Since only 1 piece of code invokes #setCacheEngine, how can the hashCode change during runtime (I am assuming that a different instance will have a different hashCode). Is there a bug here somewhere ? public class ForumRepository implements Cacheable { private static CacheEngine cache; private static ForumRepository instance; public void setCacheEngine(CacheEngine engine) { cache = engine; } public synchronized static void start() { instance = new ForumRepository(); } public synchronized static void addForum( ... ) { cache.add( .. ); System.out.println( cache.hashCode() ); // snipped } public synchronized static void getForum( ... ) { ... cache.get( .. ); System.out.println( cache.hashCode() ); // snipped } }

  • Vertical line on HxW canvas of pixels

    - by bobby williams
    I searched and found nothing. I'm trying to draw lines (simple y=mx+b ones) on a canvas of black pixels. It works fine, but no line occurs when it is vertical. I'm not sure why. My first if statement checks if the denominator is zero, therefore m is undefined and no need for a line equation. My second and third if statement check how steep it is and based on that, calculate the points in between. I don't think there is a need for other classes, since I think there is a bug in my code or I'm just not translating the mathematics into code properly. If more is needed, I'll be happy to post more. /** * Returns an collection of points that connects p1 and p2 */ public ArrayList getPoints() { ArrayList points = new ArrayList(); // checks to see if denominator in m is zero. if zero, undefined. if ((p2.getX() - p1.getX()) == 0) { for (int y = p1.getY(); y<p2.getY(); y++) { points.add(new Point(p1.getX(), y, getColor())); } } double m = (double)(p2.getY()-p1.getY())/(double)(p2.getX()-p1.getX()); int b = (int)(p1.getY() - (m * p1.getX())); // checks to see if slope is steep. if (m > -1 || m < 1) { for (int x = p1.getX(); x<p2.getX(); x++) { int y = (int) ((m*x)+b); points.add(new Point(x, y, getColor())); } } // checks to see if slope is not steep. if (m <= -1 || m >= 1) { for (int y = p1.getY(); y<p2.getY(); y++) { int x = (int) ((y-b)/m); points.add(new Point(x, y, getColor())); } } return points; }

  • Subversion update misses new directories

    - by Mike Q
    Hi all, Periodically we have trouble with SVN when doing updates. Very occasionally when someone adds a new directory doing an update through Tortoise doesn't work. If we do a "Fully Recursive" update using "Update from revision..." option then it picks it up fine. I'm poked around and seen this question which is virtually identical but with no answer. I've found the item on the SVN website, referenced by that post, that talks about an issue in 1.6.0 which is now fixed. However my SVN version is 1.6.9 and Tortoise is 1.6.7 so I wouldn't expect to have this problem any more. This only seems to occur with new directories, never seen it for individual files. We may have had older versions of Tortoise at one point (can't remember which tho) so maybe some issue has been introduced into our repo that an upgrade doesn't solve. We have the workaround but it wastes a few minutes of head-scratching after failed builds to figure it out and people who haven't come across this problem before really struggle until they ask someone else. Anyone know if this is a known bug and any permanent solutions? Thanks.

  • What are your Programming Falacies/Myths?

    - by pms1969
    I recently started a new job and as is typical of all jobs, if you've left, you get blamed for everything. Not long after I started there was a change required for an app (web based) that we maintain, and it was quickly pointed out that the actual code for this site had been lost a long time ago, and the only changes we could make to the it were ones that required changes to mark-up [it was a pre-compiled site]. Being new, I needed a little help finding my way around the code, and enlisted the services of one of my colleagues. Made my changes, and then re-enlisted his help to deploy it. While prepping for the deployment (getting the app on the QA server) we discovered that there were actually 2 different, very similarly named, folders in our source repository. It transpired that for the last year or so, mark-up changes had been made to the site directly, and these were the only differences with the code in the slightly incorrectly named folder in source control. So we did have all the code, and can now properly support the site. This put me in mind of a trick we played on a junior programmer once in a previous job, where we told him he couldn't/shouldn't do a certain thing in code as this would likely bring the server to it's knees and cost the company thousands of pounds (a gag that last months :-). And another one in the first programming job I took on - the batch commission run was just going to crash once a month and there was nothing to be done about it, causing a call out, and call out compensation for the on-call guy (a bug I fixed as soon as I became the on-call guy - 2am call outs don't work for me). So I was wondering... What other programming fallacies/myths are out there that are worth sharing?

  • jquery focusin() and preventing bubbling.

    - by DA
    I'm showing a div via an onclick event. If you click outside the div, I want to hide it. To do so, I'm binding a one time click event on the body: $('body').one('click.myDivPopup', function(e) { ...close my div... }); Within the div itself, I tell it to not propogate events so that actually clicking within the div won't trigger a click on the body: $myDiv.click(function(e){e.stopPropagation()}); This works fine as intended. I also want to hide the div if one tabs out of the div. My thinking was that in that scenario, I could use a focusin event on the body: $('body').one('focusin.myDivPopup', function(e) { ...close my div... }); Again, I don't want the events to bubble out of the div itself, so added this: $myDiv.focusin(function(e){e.preventDefault()}); This does NOT work. Changing focus within elements within myDiv triggers the focusin event on the body. Is this maybe a bug in jQuery? If so is there a better way to accomplish this?

  • How to detect a Socket disconnection?

    - by AngryHacker
    I've implemented a task using the async Sockets pattern in Silverlight 3. I started with Michael Schwarz's implementation and built on top of that. So basically, my Silverlight app establishes a persistent socket connection to a device and then data flows both ways as necessary between the device and the Silverlight app. One thing I am struggling with is how to detect disconnection. I could think of 2 approaches: Keep-Alive. I know this can be done at the Sockets level, but I am not sure how to do this in an async model. How would the Socket class let me know there has been a disconnection. Manual keep alive. Basically, I am having the Silverlight app send a dummy packet every 20 seconds or so. If it fails, I'd assume disconnection. However, incredibly, SocketAsyncEventArgs.SocketError always reports success, even if I simply unplug the device that the Silverlight app is connected to. I am not sure whether this is a bug or what or perhaps I need to upgrade to SL4. Any ideas, direction or implementation would be appreciated.

  • Update text on CCLabelTFF end in bad access?

    - by TheDeveloper
    I'm doing a little game in Coco2D and I have a countdown clock Note: As I am just trying to fix a bug, I am not working on cleanup so the timer can stop, etc. Here is my code I'm using to setup the label and start the timer: timer = [CCLabelTTF labelWithString:@"10.0000" fontName:@"Helvetica" fontSize:20]; timerDisplay = timer; timerDisplay.position = ccp(277,310); [self addChild:timerDisplay]; timeLeft = 10; timerObject = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES]; Note: timeLeft is a double This is updateTimers's code: -(void)updateTimer { NSLog(@"Got Called!"); timeLeft = timeLeft -0.1; [timer setString:[NSString stringWithFormat:@"%f",timeLeft]]; timerDisplay = timer; timerDisplay.position = ccp(277,310); [self removeChild:timerDisplay cleanup:YES]; //[self addChild:timerDisplay]; if (timeLeft <= 0) { [timerObject invalidate]; } } When I run this I toggle between crashing on this this: [timer setString:[NSString stringWithFormat:@"%f",timeLeft]]; and in the green arrow thing it gives Thread 1: EXEC_BAD_ACCESS (code=2, address=0x8) and 0x197a7ff: movl 16(%edi), %esi and in the green arrow thing it gives Thread 1: EXEC_BAD_ACCESS (code=2, address=0x8)

  • Best way to update/insert into a table based on a remote table.

    - by martilyo
    I have two very large enterprise tables in an Oracle 10g database. One table keeps the historical information of the other table. The problem is, I'm getting to the point where the records are just too many that my insert update is taking too long and my session is getting killed by the governor. Here's a pseudocode of my update process: sqlsel := 'SELECT col1, col2, col3, sysdate FROM table2@remote_location dpi WHERE (col1, col2, col3) IN ( SELECT col1, col2, col3 FROM table2@remote_location MINUS SELECT DISTINCT col1, col2, col3 FROM table1 mpc WHERE facility = '''||load_facility||''' )'; EXECUTE IMMEDIATE sqlsel BULK COLLECT INTO table1; I've tried the MERGE statement: MERGE INTO table1 t1 USING ( SELECT col1, col2, col3 FROM table2@remote_location ) t2 ON ( t1.col1 = t2.col1 AND t1.col2 = t2.col2 AND t1.col3 = t2.col3 ) WHEN NOT MATCHED THEN INSERT (t1.col1, t1.col2, t1.col3, t1.update_dttm ) VALUES (t2.col1, t2.col2, t2.col3, sysdate ) But there seems to be a confirmed bug on versions prior to Oracle 10.2.0.4 on the merge statement when doing a merge using a remote database. The chance of getting an enterprise upgrade is slim so is there a way to further optimize my first query or write it in another way to have it run best performance wise? Thanks.
