    - by ereffe
    i have 2 queries in vb.net with an if clause - if x=0 then insert into table1 else update table1 both queries have 5 fields. now what i want to do is after this insert or update takes place, i need to look at this inserted/updated record and compare it with another table (table2).

  • Does having a longer string in a SQL Like expression allow hinder or help query executing speed?

    - by Allain Lalonde
    I have a db query that'll cause a full table scan using a like clause and came upon a question I was curious about... Which of the following should run faster in Mysql or would they both run at the same speed? Benchmarking might answer it in my case, but I'd like to know the why of the answer. The column being filtered contains a couple thousand characters if that's important. SELECT * FROM users WHERE data LIKE '%=12345%' or SELECT * FROM users WHERE data LIKE '%proileId=12345%' I can come up for reasons why each of these might out perform the other, but I'm curious to know the logic.

  • Why do I get strange output from Perl using SQL?

    - by benjamin button
    Here is my Perl code: foreach my $line (@tmp_field_validation) { chomp $line; my ($cycle_code,$cycle_month,$cycle_year)= split /\s*\|\s*/, $line; $cycle_code=~ s/^\s*(.*)\s*$/$1/; $cycle_month=~ s/^\s*(.*)\s*$/$1/; $cycle_year=~ s/^\s*(.*)\s*$/$1/; print "$line\n"; print "$cycle_code|$cycle_month|$cycle_year"; } Here is the output: 1 10 2009 1 10 2009|| What's wrong over here? I expected the pipes to be between the variables. Why are the pipes getting printed after all the three variables?

  • PL/SQL 'select in' from a list of values whose type are different from the outer query

    - by Attilah
    I have the following tables : Table1 ( Col1 : varchar2, Col2 : number, Col3 : number) Table2 ( Col1 : number, Col2 : varchar2, Col3 : varchar2) I want to run a query like this : select distinct Col2 from Table1 where Col1 in ( select Col1 from Table2 ) Table1.Col1 is of type varchar2 while Table2.Col1 is of type number. so, I need to do some casting, it seems but it fails to succeed. The problem is that any attempts to run the query returns the following error : ORA-01722: invalid number 01722. 00000 - "invalid number" *Cause: *Action: Table1.Col1 contains some null values.

  • Is it possible to run a SQL-only file from a "rake db:create"?

    - by Somebody still uses you MS-DOS
    I'm trying to install a software called Teambox in my Dreamhost shared account. I have no experience with Rails. I just want to install the software in the shared hosting. In this shared hosting, all dependencies are ok, but I have to create the dabatase from their panel. I can't create in command line (ssh). So, when I run "rake db:create" these's an error, because the db already exists (because I created in panel). I've already contacted support. They can't change this policy. How do I populate my tables "by hand" in this case? Which files should I look inside Teambox's folder... Thanks!

  • MS SQL 2005: Why would a delete from a temp table hang forever?

    - by Dr. Zim
    DELETE FROM #tItem_ID WHERE #tItem_ID.Item_ID NOT IN ( SELECT DISTINCT Item_ID FROM Item_Keyword JOIN Keyword ON Item_Keyword.Keyword_ID = Keyword.Record_ID WHERE Keyword LIKE @tmpKW) The Keyword is %macaroni%. Both temp tables are 3300 items long. The inner select executes in under a second. All strings are nvarchar(249). All IDs are int. Any ideas? I executed it (it's in a stored proc) for over 12 minutes without it finishing.

  • sortable list using jquery ui not passing updated list order

    - by Matthew Berman
    I am following the sortable lists railscast and got everything working except when I sort, the same (original) order gets passed to the update method each time, so it doesn't update the true order. Here's the code: In the view: %tbody#lineup{"data-update-url" => sort_lineups_url} - @lineup.pieces.each_with_index do |piece, index| = content_tag_for :tr, piece do = render 'piece', :piece => piece, :index => index and pieces.js.coffee: jQuery -> $('#lineup').sortable( axis: 'y' update: -> $.post($(this).data('update-url'), $(this).sortable('serialize')) ); sort and show methods of lineupscontroller: def show @lineup = Lineup.find_by_user_id(current_user.id) @pieces = @lineup.pieces.order("position") end def sort params[:piece].each_with_index do |id, index| current_user.lineup.pieces.update_all({position: index+1}, {id: id}) end render nothing: true end and the update request: Started POST "/lineups/sort" for 127.0.0.1 at 2012-06-24 20:06:14 -0700 Processing by LineupsController#sort as */* Parameters: {"piece"=>["8", "2", "1", "4", "3", "7"]} User Load (0.4ms) SELECT `users`.* FROM `users` WHERE `users`.`id` = 2 LIMIT 1 Lineup Load (0.6ms) SELECT `lineups`.* FROM `lineups` WHERE `lineups`.`user_id` = 2 LIMIT 1 SQL (2.9ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 1 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 8 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 2 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 2 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 3 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 1 SQL (0.5ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 4 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 4 SQL (0.6ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 5 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 3 SQL (0.5ms) UPDATE `pieces` INNER JOIN `piece_lineups` ON `pieces`.`id` = `piece_lineups`.`piece_id` SET `position` = 6 WHERE `piece_lineups`.`lineup_id` = 3 AND `pieces`.`id` = 7 Rendered text template (0.0ms) so each time i drag+drop the list, it sends the same order again. what am I doing wrong that the params isn't passing the right, updated order?

  • Intelligently removing excess indention from a string

    - by TravisO
    I'm trying to remove some excessive indention from a string, in this case it's SQL, so it can be put into a log file. So I need the find the smallest amount of indention (aka tabs) and remove it from the front of each line, but the following code ends up printing out exactly the same, any ideas? In other words, I want to take the following SELECT blah FROM table WHERE id=1 and convert it to SELECT blah FROM table WHERE id=1 here's the code I tried and fails $sql = ' SELECT blah FROM table WHERE id=1 '; // it's most likely idented SQL, remove any idention $lines = explode("\n", $sql); $space_count = array(); foreach ( $lines as $line ) { preg_match('/^(\t+)/', $line, $matches); $space_count[] = strlen($matches[0]); } $min_tab_count = min($space_count); $place = 0; foreach ( $lines as $line ) { $lines[$place] = preg_replace('/^\t{'. $min_tab_count .'}/', '', $line); $place++; } $sql = implode("\n", $lines); print '<pre>'. $sql .'</pre>';

  • Simple HTML form with POST to SQL function encoding problem?

    - by Spoonk
    Hi again, I have a simple html form that submits information with POST function. But when information contains a Cyrillic characters, in table in MySql there becomes азазаза symbols instead of text. The table is on utf-8_general_ci, the site is on UTF-8 encoding. I visualize the result from this table with $query = " SELECT ".$db->nameQuote('ingredients')." FROM ".$db->nameQuote('other')." ORDER by id DESC "; $db->setQuery($query); $ingredients = $db->loadResult(); I cant understand how to tell the form to send chyrillic characters correct. Or where is the problem at all? How to fetch this characters correctly? Or how to send them correctly?

  • New SSIS tool on Codeplex – SSIS Log Analyzer

    I stumbled across a new SSIS tool on Codeplex today, the SSIS Log Analyzer which was only released a few days ago. Whilst it is a beta release and currently only supports 2005 (2008 is promised) it looks quite interesting. It seems to be a fancy log viewer, but with some clever features and a nice looking front-end. I’ve only read the documentation so far, but it has graphs and a debug view that shows your package with the colour animations similar to when debugging in BIDS, and everyone knows, the way the pretty colours and numbers change is the best bit! I’ll quote some of the features for you here and then let you make your own mind up, is it useful in the real world? Option to analyze the logs manually by applying row and column filters over the log data or by using queries to specify more complex criterions. Automated Performance Analysis which provides a quick graphical look on which tasks spent most time during package execution. Rerun (debug) the entire sequence of events which happened during package execution showing the flow of control in graphical form, changes in runtime values for each task like execution duration etc. Support for Auto Analyzers to automatically find out issues and provide suggestions for problems which can be figured out with the help of SSIS logs and/or package. Option to analyze just log file or log and package together. Provides a lightweight environment to have a quick look at the package. Opening it in BIDS takes some time as being an authoring environment it does all sorts of validations resulting in some delay. See http://ssisloganalyzer.codeplex.com/  for more details.
