问题 I have searched the site a bit for a solution to this question but have been unable to find an answer that fits precisely what I am looking for. I am attempting to count consecutive duplicate values for each ID number, ordered by the date. My current table resembles the first 3 columns of the table below, whereas the fourth column in what I would like to add. ID | date | value | consec_duplicates 1 1/1 1 0 1 1/2 2 0 1 1/3 2 1 1 1/4 2 2 1 1/5 3 0 1 1/6 3 1 2 1/14 1 0 2 1/15 2 0 2 1/16 3 0 2 1

问题 I have this code: Episode.php <?$feedback = new feedback; $articles = $feedback->fetch_all(); if (isset($_POST['name'], $_POST['post'])) { $cast = $_GET['id']; $name = $_POST['name']; $email = $_POST['email']; $post = nl2br ($_POST['post']); $ipaddress = $_SERVER['REMOTE_ADDR']; if (empty($name) or empty($post)) { $error = 'All Fields Are Required!'; }else{ $query = $pdo->prepare('INSERT INTO comments (cast, name, email, post, ipaddress) VALUES(?, ?, ?, ?, ?)'); $query->bindValue(1, $cast);

问题 I have a dataframe of the following form: ID value modified 1 AA 30 2016-11-03 2 AB 40 2016-11-04 3 AC 50 2016-11-05 4 AA 60 2016-11-06 5 AB 20 2016-11-07 I want to identify all the duplicate rows for ID column and remove rows which has comparatively old modification time. So the output will be: ID value modified 1 AC 50 2016-11-05 2 AA 60 2016-11-06 3 AB 20 2016-11-07 The code I am trying is as follows: ID<-c('AA','AB','AD','AA','AB') value<-c(30,40,50,60,20) modified<-c('2016-11-03','2016

问题 MySQL query gives duplicate data in query result. Here is how I am trying to avoid it. Actual query: $product_sql_test2 = $this->db->query("SELECT p.product_id, p.price, pc.product_id AS product_id FROM oc_product p INNER JOIN oc_product_to_category pc ON p.product_id = pc.product_id WHERE p.price BETWEEN '".$product_info['related_kv4nt_min_2']."' and '".$product_info['related_kv4nt_max_2']."' AND pc.category_id = '".$product_info['related_kv4nt_id_2']."' GROUP BY pc.product_id ORDER BY RAND(

问题 I am looking for an XSLT transformation to de-duplicate the children element of a parent. In my case both parent and children are given (i.e I don't want to deduplicate any children of any element). for example, say I want to deduplicate the <ID> children of <ROWSET> input: <ROWSET> <ROW> <ID> 1 </ID> ... <ID> 1 </ID> ... </ROW> <ROW> <ID> 2 </ID> ... <ID> 2 </ID> ... </ROW> ... </ROWSET> I want the output to be <ROWSET> <ROW> <ID> 1 </ID> ... </ROW> <ROW> <ID> 2 </ID> ... </ROW> ... </ROWSET

问题 I have rows in a list that are sometimes similar up to the first "space" character, then can change (i.e. a date afterwards). wsmith jul/12/12 bwillis jul/13/13 wsmith jul/14/12 tcruise jul/12/12 I can easily sort the lines, but I'd love to remove the duplicate later dated entry. I did find a regex suggestion, but it matches only exactly the same lines. I need to be able to mark the entire row of similar usernames in the file. In my example above, lines 1 and 3 would be highlighted. (edited
