duplicates

I want to count the same value among parent_id and id_article, but it can be 0 if there is no same value among parent_id and id_article table:t_article id_article parent_id 441 0 1093 18 18 0 3141 3130 3130 0 3140 3130 3142 3130 Expected output id_article parent_id Total 441 0 0 1093 18 0 18 0 1 3141 3130 0 3130 0 3 3140 3130 0 3142 3130 0 How do I make it happen? You can get your count by doing a sub clause and then join with your main query select a.*, coalesce(b.cnt,0) from t_article a left join ( select parent_id, sum(parent_id <> 0) cnt from t_article group by parent_id ) b on (a.id

We all know these excellent ABAP statements which allows finding unique values in one-liner: it_unique = VALUE #( FOR GROUPS value OF <line> IN it_itab GROUP BY <line>-field WITHOUT MEMBERS ( value ) ). But what about extracting duplicates? Can one utilize GROUP BY syntax for that task or, maybe, table comprehensions are more useful here? The only (though not very elegant) way I found is: LOOP AT lt_marc ASSIGNING FIELD-SYMBOL(<fs_marc>) GROUP BY ( matnr = <fs_marc>-matnr werks = <fs_marc>-werks ) ASSIGNING FIELD-SYMBOL(<group>). members = VALUE #( FOR m IN GROUP <group> ( m ) ). IF lines(

So the first fact section in this HTML import article states that html imports know better than to request (and execute - if javascript) resources multiple times. This works within the framework of HTML imports but doesn't work for other type of imports (as in javascript). In this network view of the devtools you can see Polymer.html being loaded first from javascript ( d3.js ) then again from HTML imports ( my-app.html ) which I wasn't expecting. Is there a way to explicitly tell HTML imports that a resource has already been loaded (as in from javascript in this case)? If I understand this

First of all, I would like to say that I have searched for an answer to this, but did not get an suitable solution. So I have decided to post it here. I have an ArrayList of Objects (ArrayList(Provider)). The Provider Object has First Name, Last Name, NPI Number, List (I have not listed all the fields). Provider { private long providerId; private String npiNumber; private PersonName providerName; private List<Address> providerAddresses; } Now I want to find if the ArrayList has duplicates based on these attributes (First Name, Last Name, NPI, Addresses). Each Provider will have 2 addresses.

I have a table, sessionBasket, that holds a list of the items in the shopping baskets of visitors to my site. It looks like: id INT NOT NULL AUTO_INCREMENT PRIMARY KEY usersessid VARCHAR date_added DATETIME product_id INT qty INT My add to basket script first checks for the presence of an item with the current product_id in this table associated with the usersessid and if it finds one, it updates the qty. If not, a separate query inserts a new row with the relevant information. I have since discovered there is a condition ON DUPLICATE KEY UPDATE but I'm not sure what I need to change to cause

I have the following python code which almost works for me (I'm SO close!). I have text file from one Shakespeare's plays that I'm opening: Original text file: "But soft what light through yonder window breaks It is the east and Juliet is the sun Arise fair sun and kill the envious moon Who is already sick and pale with grief" And the result of the code I worte gives me is this: ['Arise', 'But', 'It', 'Juliet', 'Who', 'already', 'and', 'and', 'and', 'breaks', 'east', 'envious', 'fair', 'grief', 'is', 'is', 'is', 'kill', 'light', 'moon', 'pale', 'sick', 'soft', 'sun', 'sun', 'the', 'the', 'the'

in CKEDITOR Document I have a node named User_Image <User_Image><sometags><sometags>sometext<sometags>sometext</sometags></sometags></sometags></User_Image> User_Image node i stored in Variable Uimage var Duimage=CKEDITOR.dom.element.createFromHtml(Uimage.getOuterHtml()); now just i created (dummy) duplicate node but this code supported me in all browsers other than IE. in IE Missing Customtags. the all tags are dynamic. then i try with following : var Duimage=ediInstance.document.createElement("User_Image"); Uimage.appendTo(Duimage); but in this code if i changed in Duimage it also affect in

I have seen the following solution used for removing duplicate rows in a DataTable using LINQ : Say if we have a DataTable with duplicate rows called dt , then the following statemend apparently does the job: IEnumerable<DataRow> uniqueContacts = dt.AsEnumerable().Distinct(DataRowComparer.Default); But this is only removing duplicate rows that are identical. What I want to do is to remove all the rows that have duplicate values of a specific row. E.g. If we have a datatable with a row called "Email", how can we remove all the rows that have the same email value? Tim.Tang simple way: use

I'm using MySQL 4.1. Some tables have duplicates entries that go against the constraints. When I try to group rows, MySQL doesn't recognise the rows as being similar. Example: Table A has a column "Name" with the Unique proprety. The table contains one row with the name 'Hach?' and one row with the same name but a square at the end instead of the '?' (which I can't reproduce in this textfield) A "Group by" on these 2 rows return 2 separate rows This cause several problems including the fact that I can't export and reimport the database. On reimporting an error mentions that a Insert has failed
