  • Would vector of vectors be contiguous?

    - by user1150989
    I need to allocate a vector of rows where row contains a vector of rows. I know that a vector would be contiguous. I wanted to know whether a vector of vectors would also be contiguous. Example code is given below vector<long> firstRow; firstRow.push_back(0); firstRow.push_back(1); vector<long> secondRow; secondRow.push_back(0); secondRow.push_back(1); vector< vector < long> > data; data.push_back(firstRow); data.push_back(secondRow); Would the sequence in memory be 0 1 0 1?

  • Using jQuery, how do I way attach a string array as a http parameter to a http request?

    - by predhme
    I have a spring controller with a request mapping as follows @RequestMapping("/downloadSelected") public void downloadSelected(@RequestParam String[] ids) { // retrieve the file and write it to the http response outputstream } I have an html table of objects which for every row has a checkbox with the id of the object as the value. When they submit, I have a jQuery callback to serialize all ids. I want to stick those ids into an http request parameter called, "ids" so that I can grab them easily. I figured I could do the following var ids = $("#downloadall").serializeArray(); Then I would need to take each of the ids and add them to a request param called ids. But is there a "standard" way to do this? Like using jQuery?

  • Get drop down selection from GridView on button press

    - by Chris Stewart
    I have an ASP.NET GridView that has four columns. The first three are typical BoundField elements bound to a DataTable. The forth is a TemplateField element that I create a DropDownList in on the OnRowCreated event for the GridView. What I'm attempting to do is walk down the data source for the GridView when a button is pressed. I really just need to get the values for columns one and four of each row. The first three columns have data as expected but the forth is displaying as empty. Is this because it wasn't a part of the DataTable originally? Is there any way to get the value for each drop down as I've described it, or will I need to rework this so each drop down list is a part of the DataTable?

  • SQL query help - merge a value to all rows in a column

    - by Tommy
    I'm trying to migrate a site from a joomla system to a drupal. The problem is that drupal needs filename and sourcepath in the same row, but joomla only has filename. I'm looking for a way to add sourcepath before the filename in all the rows in that column. I'm figuring it's the UPDATE statement that I should use, but I can't figure out how to construct the query. There's a person with a similar problem here, but I don't find the answers in that thread helpful to my problem: http://www.daniweb.com/forums/showth...t+value&page=2 Any suggestions?

  • Multi "column" DataGridView C#

    - by Wesley
    I have a DataGridView that's bound to a DataSet. It has columns DateCreated, Weight, DateUsed. Those three columns do not take up much horizontal space on DataGridView that is nearly full screen. Is it possible to have those columns wrap back to the top if the view is wide enough to support a second group of those colums. So across the header it would read DateCreated, Weight, DateUsed, DateCreated, Weight, DateUsed. Then when a row is clicked, only 3 cells would be highlighted, not all six. Is there something that can provide this functionality?

  • How can I loop through each of the days of a given week in Ruby?

    - by Angela
    I am defining monday and friday using the following: @monday = Date.today.at_beginning_of_week @friday = 5.days.since(@monday) But I actually need, for any given day, to loop through Monday, Tuesday, Wednesday and take that date and put the output into a column. <th>Monday</th> <th>Tuesday</th> etcetera A given row, for example, would be: <tr><td>value(monday)</td><td>value(tuesday)</td><td>value(wednesday)</td></tr> This is where value is a method that takes args date. What's the cleanest way to do this? Thanks.

  • MySQL - Counting rows in preparation for greatest-n-per-group not working?

    - by John M
    Referring to SO and other sites have given me examples of how to use MySQL to create a 'greatest-n-per-group' query. My variant on this would be to have a query that returns the first 3 rows of each category. As the basis for this I need to sort my data into a usable sequence and that is where my problems start. Running just the sequence query with row numbering shows that changes in category are mostly ignored. I should have 35 categories returning rows but only 5 do so. My query: set @c:=0; set @a:=0; SELECT IF(@c = tdg, @a:=@a+1, @a:=1) AS rownum, (@c:=tdg) , julian_day, sequence, complete, year, tdg FROM tsd WHERE complete = 0 order by tdg, year, julian_day, sequence Do I have a syntax mistake with this query?

I have tried textread,fscanf and a few other matlab commands but the result is that they all read each row in decimal format and create a 840946*1 array.I want to create a 840946*125 array to compute a column wise sum. Kindly help, Thanks!

  • MySQL Full-text Search Workaround for innoDB tables

    - by Rob
    I'm designing an internal web application that uses MySQL as its backend database. The integrity of the data is crucial, so I am using the innoDB engine for its foreign key constraint features. I want to do a full-text search of one type of records, and that is not supported natively with innoDB tables. I'm not willing to move to MyISAM tables due to their lack of foreign key support and due to the fact that their locking is per table, not per row. Would it be bad practice to create a mirrored table of the records I need to search using the MyISAM engine and use that for the full-text search? This way I'm just searching a copy of the data and if anything happens to that data it's not as big of a deal because it can always be re-created. Or is this an awkward way of doing this that should be avoided? Thanks.

  • Set to null a parent record so that children are removed: howto?

    - by EugeneP
    How to delete a child row (on delete cascade ?) when setting a null value on a parent? Here's the db design. table A [id, b_id_1, b_id_2] table B [id, other fields...] b_id_1 and b_id_2 can be NULL if any of them is null, it means NO B records for corresponding FK (there are 2 of them) so (b_id_1,b_id_2) can be (null,null), (100, null), (null, 100_or_any_other_number) etc How in one SQL query both set b_id_1 or b_id_2 to null and delete all rows from B that have this id? What FK design should be applied to the 2 tables? what foreign keys should be added? A - B (FK_1: A.b_id_1 references B.id, FK_2: A.b_id_2 references B.id) and also B-A (FK_3: B.id references A.b_id_1, FK_4: B.id references A.b_id_2) ? But again, setting an A's b_id_1 or A's b_id_2 to null - will it remove any of B's records? I don't think so. So how to do that?

  • HTML, CSS: how can I merge these divs in order to use float:left property on their children ?

    - by Patrick
    hi, I've 2 sets of thumbnails and in each set I'm displaying them one nearby each other in 4 columns using float:left. I would like to "merge" the 2 sets (but I cannot change the html code) because I want the thumbnails of the second set floating right after the last thumbnail of the first set. In other terms, if in the last row there are only 2 thumbnails and the last 2 columns are empty, the thumbnails of the second set should fill the empty columns of the last row of the first set.

Maybe one loop instead 2?

  • JAVA-SQL- Data Migration - ResultSets comparing Failing JUnit test

    - by user1865053
    I CANNOT get this JUnit Test to pass for the life of me. Can somebody point out where this has gone wrong. I am doing a data migration(MSSQL SERVER 2005), but I have the sourceDBUrl and the targetDCUrl the same URL so to narrow it down to syntax errors. So that is what I have, a syntax error. I am comparing the results of a table for the query SELECT programmeapproval, resourceapproval FROM tr_timesheet WHERE timesheetid = ? and the test always fails, but passes for other junit tests I have developed. I created 3 diffemt resultSetsEqual methods and none work. Yet, some other JUnit tests I have developed have PASSED. THE QUERY: SELECT timesheetid, programmeapproval, resourceapproval FROM tr_timesheet Returns three columns timesheetid (PK,int, not null) (populated with a range of numbers 2240 - 2282) programmeapproval (smallint,not null) (populated with the number 1 in every field) resourceapproval (smallint, not null) (populated with a number 1 in every field) When I run the query that is embedded in the code it only returns one row with the programmeapproval and resourceapproval columns and both field populated with the number 1.

  • How to concatenate text on existing database entry?

    - by Starx
    I have a table, whose fields are id, name, link the link holds the name of the page like "link" = "index.php". Now I want to update this field and add "page=" in front of "index.php". Using this method I would like to update every entry in my table. My desired SQL syntax need to be something like this UPDATE mytable set link= 'page=' + <existing value of link> WHERE 1; I am using 'WHERE 1;' to denote every row. Anyone know how to accomplish this?

  • How to seperate database entries and display them as individual records using PHP?

    - by Clark
    I used to have database entries separated by ampersands (&), but this was causing certain search issues so I decided to encapsulate my entries on both sides by $ and & symbols like: $this& But I am having trouble displaying all the entries of a cell as indiivdual records. Before I used: $unsplitItems = $row['files']; $files = explode("@", $unsplitItems); foreach ($files as $file) { if(strlen($file)) { echo "<li>$file</li>"; } } Any idea how I can split my records and display all the items in the array as individual entries?

  • Activiti Engine: Task Event - User is null

    - by sockeqwe
    I have a problem, which should be simple to solve, but i can't find the method to call to solve this problem: My problem is, that every Task Event (org.activiti.engine.task.Event) returnes null by calling Event.getUserId(); If I take a look into the database I see that the database table ACT_HI_COMMENT has null as value for the column USER_ID_ for every row. I generate these TaskEvents programmatically by calling (for example) processEngine.getTaskService().addComment(task.getId(), null, commentMessage); processEngine.getTaskService().addUserIdentityLink(task.getId(), user.getId(), IDENTITY_LINK_OBSERVER); I guess there is a simple method that I must call to solve this problem, something like processEngine.setCurrentUser(authenticatedUser.getId()); Any suggestions?

  • UITableViewController executes delate functions before network request finishes

    - by user1543132
    I'm having trouble trying to populate a UITableView with the results of a network request. It seems that my code is alright as it works perfectly when my network is speedy, however, when it's not, the function - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath- still executes, which results in a bad access error. I presume that this is because the array that the aforesaid function attempts to utilize has not been populated. This brings me to my question: Is there anyway that I can have the UITableView delegate methods delayed to avoid this? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"AlbumsCell"; //UITableViewCell *basicCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; AlbumsCell *cell = (AlbumsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { **// Here is where the Thread 1: EXC_BAD_ACCESS (code=2 address=0x8)** cell = [[[AlbumsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } Album *album = [_albums objectAtIndex:[indexPath row]]; [cell setAlbum:album]; return cell; }

  • Most efficient way to maintain a 'set' in SQL Server?

    - by SEVEN YEAR LIBERAL ARTS DEGREE
    I have ~2 million rows or so of data, each row with an artificial PK, and two Id fields (so: PK, ID1, ID2). I have a unique constraint (and index) on ID1+ID2. I get two sorts of updates, both with a distinct ID1 per update. 100-1000 rows of all-new data (ID1 is new) 100-1000 rows of largely, but not necessarily completely overlapping data (ID1 already exists, maybe new ID1+ID2 pairs) What's the most efficient way to maintain this 'set'? Here are the options as I see them: Delete all the rows with ID1, insert all the new rows (yikes) Query all the existing rows from the set of new data ID1+ID2, only insert the new rows Insert all the new rows, ignore inserts that trigger unique constraint violations Any thoughts?
