问题 I have table like this- id object_id product_id 1 1 1 2 1 1 4 2 2 6 3 2 7 3 2 8 1 2 9 1 1 I want to delete all rows except these- 1 1 1 4 2 2 6 3 2 9 1 2 Basically there are duplicates and I want to remove them but keep one copy intact. what would be the most efficient way for this? 回答1: If this is a one-off then you can simply identify the records you want to keep like so: SELECT MIN(id) AS id FROM yourtable GROUP BY object_id, product_id; You want to check that this works before you do the

问题 Thanks for your help i'm stuck on this problem. Let me explain it, i have this kind of table : | domain | creationdate | value 1 | value 2 | |--------|---------------------|---------|---------| | abc | 2013-05-28 15:35:01 | value 1 | value 2 | | abc | 2013-04-30 12:10:10 | value 1 | value 2 | | aaa | 2011-04-02 13:10:10 | value 1 | value 2 | | bbb | 2012-02-12 10:48:10 | value 1 | value 2 | | bbb | 2013-04-15 07:15:23 | value 1 | value 2 | And i want to select (with subqueries) this : |

问题 due to some reason I'm getting the search bar in duplicate. I suspect I have a double function command somewhere...but I can not find it. Can someone look at the code with "fresh eyes" and try to find my mistake? as wordpress keeps giving me 2 search bars instead of one I am using Notepad++, Bootstrap v 3.0 and Wordpress 4.7.8 Here is the code <?php get_header(); ?> <div class="row"> <div class="col-xs-12 col-sm-8"> <div class="row text-center no-margin"> <?php $currentPage = (get_query_var(

问题 We have a list of parts in Excel in a certain order. For reasons I won't get into, we need to highlight when there are duplicates that aren't next to each other. Currently, I'm using this formula in a conditional format to do the job. =AND(COUNTIF($A$2:$A$82,$A2)>1,$A1<>$A2,$A2<>$A3) This mostly works well except in cases where there are pairs of duplicates like in the example below, we would want FO-1694 to be highlighted, because they aren't all next to each other. But we would not want

问题 I am trying to do a stock count through product stores but have several part numbers that are listed twice (Column A). When I try to consolidate these I recieve the error 'no data consolidated' which I think is caused by Columns B-F (which will always be the same if Column A value is the same). I want to consolidate the rows where columns A-F are the same, into a singular row with Column G representing the subtotal of Column F for all duplicate rows.

问题 Situation is that I in my project use library A. I also import external library which also has itself a library A. So as you can assume, when I try to compile, I receive Multiple DEX files define error which means that there are duplications. However, If I remove my library from the project, I cannot use its provided methods. And I cannot find how can I remove that library from the module. Any suggestions? 回答1: You should be able to exclude it like this: compile('library:1.0.0') { exclude

问题 I want to efficiently find the intersection of two lists , keeping duplicates from both , e.g. A=[1,1,2,3], B=[1,1,2,4] should return [1,1,1,1,2] I know a similar question was asked previously (Python intersection of two lists keeping duplicates) however this does not help me because only the duplicates from one list are retained. The following works def intersect(A,B): C=[] for a in A: for b in B: if a==b: C.append(a) return C however it isn't efficient enough for what I'm doing! To speed
