  • How do I return the rows from an Oracle Stored Procedure using SELECT?

    - by Calanus
    I have a stored procedure which returns a ref cursor as follows: CREATE OR REPLACE PROCEDURE AIRS.GET_LAB_REPORT (ReportCurTyp OUT sys_refcursor) AS v_report_cursor sys_refcursor; report_record v_lab_report%ROWTYPE; l_sql VARCHAR2 (2000); BEGIN l_sql := 'SELECT * FROM V_LAB_REPORT'; OPEN v_report_cursor FOR l_sql; LOOP FETCH v_report_cursor INTO report_record; EXIT WHEN v_report_cursor%NOTFOUND; END LOOP; CLOSE v_report_cursor; END; I want to use the output from this stored procedure in another select statement like: SELECT * FROM GET_LAB_REPORT() but I can't seem to get my head around the syntax. Any ideas?

  • Inserting rows while fetching(from another table) in SQLite

    - by Samuel
    I'm getting this error no matter what with python and sqlite. File "addbooks.py", line 77, in saveBook conn.commit() sqlite3.OperationalError: cannot commit transaction - SQL statements in progress The code looks like this: conn = sqlite3.connect(fname) cread = conn.cursor() cread.execute('''select book_text from table''') while True: row = cread.fetchone() if row is None: break .... for entry in getEntries(doc): saveBook(entry, conn) Can't do a fetchall() because table and column size are big, and the memory is scarce. What can be done without resorting to dirty tricks(as getting the rowids in memory, which would probably fit, and then selecting the rows one by one)?.

  • NetworkOnMainThreadException while using AsyncTask

    - by Fansher
    Im making an app that uses the internet to retrive information. I get an NetworkOnMainThreadException as i tried to run it on 3.0 and above and have therefore tried to set it up using AsyncTask, but it still gives the exception and i don't know what is wrong. Oddly enough i read on this thread Android NetworkOnMainThreadException inside of AsyncTask that if you just removes the android:targetSdkVersion="10" statement from the manifest file it will be able to run. This works but i don't find it as the right solution to solve the problem this way. So if anyone can tell me what im doing wrong with the AsyncTask i will really appriciate it. Also if there is anybody that knows why removing the statement in the manifest makes it work, im really interested in that also. My code looks like this: public class MainActivity extends Activity { static ArrayList<Tumblr> tumblrs; ListView listView; TextView footer; int offset = 0; ProgressDialog pDialog; View v; String responseBody = null; HttpResponse r; HttpEntity e; String searchUrl; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

  • How to get a Javascript routine to NOT act if it's in a text box?

    - by talkingnews
    I've got a simple page, and in that page runs a simple jquery keypress routine to catch clicks of the numbers 1 to 9 (has to be that to pass RNIB accessibility test). And in that page is a form, which can have numbers entered as part of a postcode. http://find.talking-newspapers.co.uk/result.php?addressInput=kingston Scroll to the bottom, try typing 8 or 9 for example. The text is entered, but it also acts on the keypress. Expected, but not good. I'm aware of various things like document.getElementById, but I can't figure out how to put these together to ensure that while the cursor is in the text input box, it doesn't act out the keypress catcher.

  • LINQ causing my obfuscator to break

    - by JL
    I have the following LINQ that is causing my obfuscator to break. .Where(f => f.FileName == fileName).OrderByDescending(f => f.Position).FirstOrDefault(); Is there another way I could reword this LINQ statement to test against my obfuscator? I've reported the bug, but it could take 1-2 months to fix, so I need to try recode this LINQ in the meantime.

  • Fitts Law, applying it to touch screens

    - by Caylem
    Been reading a lot into UI design lately and Fitts Law keeps popping up. Now from what i gather its basically the larger an item is, and the closer it is to your cursor, the easier it is to click on. So what about touch screen devices where the input comes from multiple touches or just single touches. What are the fundamentals to take into account considering this? Should it be something like, the hands of the user are on the sides of the device so the buttons should be close to the left and right hand sides of the device? Thanks

  • Firefox, prevent rendering between javascript statements.

    - by Erik
    I'm trying to create some kind of zoom around the mouse cursor feature on my website which ultimately runs these two lines (+ the same for height/scrollTop). canvas.style.width = someValue; canvas.parentNode.scrollLeft = someOtherValue; The problem is that in firefox(3.6) the page is re-rendered directly after the first row has been executed and since the view is depending on both values this means that every time i recalculate the view firefox will will render an invalid view before the correct one, in other words creating flicker. I've tried swapping the two rows but get the same problem. In chrome, opera and IE this doesn't happen. Both lines are executed before any rendering is done. Is there any way to lock the rendering manually, maybe something like this? document.disableRendering(); //fantasy function canvas.style.width = someValue; canvas.parentNode.scrollLeft = someOtherValue; document.enableRendering(); //fantasy function

  • How does Gmail do comet on Opera?

    - by Unknown
    I would like to know how Gmail (or anyone else) does comet on Opera. Here is what I know so far from my experiments. It doesn't use the event-source tag which is broken in Opera 10.51. It doesn't use iframe which displays a spinning throbber and a busy mouse cursor. It doesn't use responseText on xmlhttprequest when readyState = 3 which is known to be broken on Opera. I tried seeing how it was done in mibbit and etherpad, and I found that they both use long-polling.

  • Activating Webkit CSS3 animation using Javascript

    - by jeffreyveon
    I am looking to use Webkit CSS3 to move a absolutely positioned DIV from one location to another on the screen when a button is pressed, by changing its left and right CSS properties. However, all the examples for doing this that I saw use a static CSS rule to apply this transition. I don't know the new position before hand, so how do I apply this CSS3 transition dynamically?

  • Creating standalone, console (shell) for domain-specific operations

    - by mr.b
    Say that I have a system service, and I want to offer a low-level maintenance access to it. For that purpose, I'd like to create a standalone, console application that somehow connects to server process and lets user type in commands, allow it to use auto-completion and auto-suggestion on single/double TAB press (just like linux bash shell, mysql cli, cmd.exe, and countless others), allow command line editing capabilities (history, cursor keys to move around text..), etc. Now, it's not that much of a problem to create something like that by rolling my own from scratch, handling user input, scanning pressed keys, and doing correct actions. But, why reinvent the wheel? Is there some library/framework that helps with this kind of problems, just like readline library that offers improved command-line editing capabilities under linux? Of course, this new "shell" would respond only to valid, domain-specific commands, and would suggest valid arguments, options, switches... Any ideas? Thanks!

  • pipelined function

    - by user289429
    Can someone provide an example of how to use parallel table function in oracle pl/sql. We need to run massive queries for 15 years and combine the result. SELECT * FROM Table(TableFunction(cursor(SELECT * FROM year_table))) ...is what we want effectively. The innermost select will give all the years, and the table function will take each year and run massive query and returns a collection. The problem we have is that all years are being fed to one table function itself, we would rather prefer the table function being called in parallel for each of the year. We tried all sort of partitioning by hash and range and it didn't help. Also, can we drop the keyword PIPELINED from the function declaration? because we are not performing any transformation and just need the aggregate of the resultset.

  • Parallel programming in C#

    - by Alxandr
    I'm interested in learning about parallel programming in C#.NET (not like everything there is to know, but the basics and maybe some good-practices), therefore I've decided to reprogram an old program of mine which is called ImageSyncer. ImageSyncer is a really simple program, all it does is to scan trough a folder and find all files ending with .jpg, then it calculates the new position of the files based on the date they were taken (parsing of xif-data, or whatever it's called). After a location has been generated the program checks for any existing files at that location, and if one exist it looks at the last write-time of both the file to copy, and the file "in its way". If those are equal the file is skipped. If not a md5 checksum of both files is created and matched. If there is no match the file to be copied is given a new location to be copied to (for instance, if it was to be copied to "C:\test.jpg" it's copied to "C:\test(1).jpg" instead). The result of this operation is populated into a queue of a struct-type that contains two strings, the original file and the position to copy it to. Then that queue is iterated over untill it is empty and the files are copied. In other words there are 4 operations: 1. Scan directory for jpegs 2. Parse files for xif and generate copy-location 3. Check for file existence and if needed generate new path 4. Copy files And so I want to rewrite this program to make it paralell and be able to perform several of the operations at the same time, and I was wondering what the best way to achieve that would be. I've came up with two different models I can think of, but neither one of them might be any good at all. The first one is to parallelize the 4 steps of the old program, so that when step one is to be executed it's done on several threads, and when the entire of step 1 is finished step 2 is began. The other one (which I find more interesting because I have no idea of how to do that) is to create a sort of worker and consumer model, so when a thread is finished with step 1 another one takes over and performs step 2 at that object (or something like that). But as said, I don't know if any of these are any good solutions. Also, I don't know much about parallel programming at all. I know how to make a thread, and how to make it perform a function taking in an object as its only parameter, and I've also used the BackgroundWorker-class on one occasion, but I'm not that familiar with any of them. Any input would be appreciated.
