  • db2 stored procedure. locking / releasing table

    I use a stored procedure to read/update/return certain fields in a journaled as400 table. I want to lock the table first and then release it after the record is updated. I tried tons of stuff, but releasing table is a problem. SP defines and opens cursor, selects record into variables and updates the record. I tried 'begin atomic', then lock table in exclusive mode and then when it's over, it doesn't release. Is there any statement i missing or do i need to compile it with certain parameters? I use a simple create procedure statement in AS400 navigator's sql panel to compile it. Will very appreciate some help with example. Thanks.

  • Javascript dynamic table memory usage

    - by Dan
    I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?

    Write a JavaScript that accepts a number from the user using the “prompt” function. Then it draws a table in the HTML document that has the user specified number of rows and columns. In each table data, it displays the result of the math operation (row raised to the power of column). For example, if the user enters the number 3, the JavaScript should draw the following table: 1 1 1 2 4 8 3 9 27

  • MySql query and table optimisation

    - by Cheeky
    Hi everyone. I am trying to run the following simple query on a table with 500K records. SELECT COUNT(*) AS impressionCount FROM impression WHERE 0 = 0 AND impressionObjectId1 = 'C69A54B8-B828-E2E4-2319A93011DF4120' AND impressionObjectId2 = '1'; This query is taking 10 seconds to run. I have tried creating individual indexes for the impressionObjectId1 and impressionObjectId2 columns, as well as a composite index using both. The composite worked well for a while, but now it is also slow. Here is my table structure: DROP TABLE IF EXISTS `impression`; CREATE TABLE `impression` ( `impressionId` varchar(50) NOT NULL, `impressionObjectId1` varchar(50) NOT NULL, `impressionObjectId2` varchar(50) default NULL, `impressionStampDate` datetime NOT NULL, PRIMARY KEY (`impressionId`), KEY `IX_object` (`impressionObjectId1`,`impressionObjectId2`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC COMMENT='InnoDB free: 191488 kB'; Any advice would be greatly appreciated. Thanks EDIT: When adding an EXPLAIN, this is the output: 1, 'SIMPLE', 'impression', 'ref', 'IX_object', 'IX_object', '105', 'const,const', 304499, 'Using where; Using index'

  • SQL update a table with a foreign key

    - by drousseau
    I have a categories table, which one of the fields serves as the foreign key for a sub-categories table. One field that serves as part of the primary key for each table is the language id. I need to update these in both tables. Basically, wherever the language id = x in both tables, I need to set it to y. When I try to do an update on either table, I get a 'The UPDATE statement conflicted with the REFERENCE constraint..' which refers to the foreign key constraint. How can I update the language field on both of these tables?

    If I have the following: <table> <thead> <tr> <th><a href="Index.cfm?Sort=0">First</a></th> <th><a href="Index.cfm?Sort=1">Second</a></th> <th><a href="Index.cfm?Sort=2">Third</a></th> </tr> </thead> <tbody> <tr> <td>A</td> <td class="num">123</td> <td>XYZ</td> </tr> </tbody> </table> Q: How do I sort the table body based upon which table header cell was clicked? <script> $('th a').click(function() { var $this = $(this).closest('th'); console.log($this.index()); return false; }); </script> (I made each of the table header cells hyperlinks so that if the user has JavaScript turned off, it will follow the link and be sorted on the server side).

    - by user1908568
    I am trying to generate a table dynamically using ajax call. To simplify things i have just added my code to js fiddle here - http://jsfiddle.net/5yLrE/81/ As you click on the button "HI" first two columns are created properly.. but some how as the td length reaches 2 . its not creating another row. The reason is that when i do find on the table elements its actually retrieving the children table elements. Can some one pls help. I want a two column table.. Thank you. sample code: var tr = $("#maintable tbody tr:first"); if(!tr.length || tr.find("td:first").length >= max) { $("#maintable").append("<tr>"); } if(count==0) { $("#maintable tr:last").append("<td>hi"+content+"</td>"); }

  • why Haskell can deduce [] type in this function

    - by Sili
    rho x = map (((flip mod) x).(\a -> a^2-1)) (rho x) This function will generate an infinite list. And I tested in GHCi, the function type is *Main> :t rho rho :: Integral b => b -> [b] If I define a function like this fun x = ((flip mod) x).(\a -> a^2-1) The type is *Main> :t fun fun :: Integral c => c -> c -> c My question is, how can Haskell deduce the function type to b - [b]? We don't have any [] type data in this function. Thanks!

  • difficulty with deleting a function from jquery snippet

    - by user1691389
    I'm trying to get rid of a function that appends a loading gif while the script is busy ajax'ing in new content, but I keep breaking the script so I'm posting it here hoping someone can just kindly edit it for me correctly. (I'd like to get rid of everything that has to do with #load and keep everything else intact.) $('#header_nav_content_container a, a.scroll_to_top, a.clear_banner, a.desire').not('.exception').click(function(){ var toLoad = $(this).attr('href')+' #content'; $('#content').hide(1555,'easeInOutQuint',loadContent); $('#load').remove(); $('body').append('<span id="load">LOADING...</span>'); $('#load').fadeIn(888); window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-0); function loadContent() { $('#content').load(toLoad,'',showNewContent); } function showNewContent() { $('#content').show(777,'',hideLoader); } function hideLoader() { $('#load').fadeOut(888); } return false; }); Thanks for your help.

    - by Andha
    I'm going to delete data in an SQL Server table (parent) which has a relationship with another table (child). I tried the basic Delete query. But it isn't working (and I know it won't). DELETE FROM table WHERE ... It returned following error The DELETE statement conflicted with the REFERENCE constraint ... I need to keep the table's schema. I know that I just need to add some words in the query, I've ever done this before, but I just couldn't recall it.

  • mysql query for change in values in a logging table

    - by kiasectomondo
    I have a table like this: Index , PersonID , ItemCount , UnixTimeStamp 1 , 1 , 1 , 1296000000 2 , 1 , 2 , 1296000100 3 , 2 , 4 , 1296003230 4 , 2 , 6 , 1296093949 5 , 1 , 0 , 1296093295 Time and index always go up. Its basically a logging table to log the itemcount each time it changes. I get the most recent ItemCount for each Person like this: SELECT * FROM table a INNER JOIN ( SELECT MAX(index) as i FROM table GROUP BY PersonID) b ON a.index = b.i; What I want to do is get get the most recent record for each PersonID that is at least 24 hours older than the most recent record for each Person ID. Then I want to take the difference in ItemCount between these two to get a change in itemcount for each person over the last 24 hours: personID ChangeInItemCountOverAtLeast24Hours 1 3 2 -11 3 6 Im sort of stuck with what to do next. How can I join another itemcount based on latest adjusted timestamp of individual rows?
