duplicates

问题 We have 4 React components bundled with Webpack (version 1): A, B, C and D. The dependency tree looks like this: A B D C D We want each component to be reusable, so we use webpack to generate a UMD module. The generated bundle for each component is located in ./dist/index.js , and the package.json of each component sets this script as the entry point for the library: "main": "./dist/index.js" This is the webpack config file for component A: const webpack = require('webpack'); const

问题 I am looking to find an effective way to delete duplicated records from my database. First, I used a stored procedure that uses joins and such, which caused the query to execute very slow. Now, I am trying a different approach. Please consider the following queries: /* QUERY A */ SELECT * FROM my_table WHERE col1 = value AND col2 = value AND col3 = value This query just executed in 12 seconds, with a result of 182.400 records. The row count in the table is currently 420.930.407, and col1 and

问题 I'm trying to import some data from a MS-Access file to my SQL Server database. I keep getting primary key errors because some of the data overlaps. Therefore I tried using ON DUPLICATE KEY UPDATE as well as INSERT IGNORE . Both seem to be unknown to my SQL Server (running 2008 R2) as I get syntax errors. Do I need some add-on library or is INSERT IGNORE and ON DUPLICATE KEY not usable when inserting with a select query to .mdb? Here's the code snippet: INSERT INTO XCManager.XC_DATA1 (STATION

问题 First of all, the table I'm struggling with: DispatchLocations ================= DispatchID int StopNumber int Arrived bool Departed bool The idea is that on a trucking route, there are many stops in a dispatch. This is a list of each location on each dispatch (essentially, it's a route table). In this view, there should only be one dispatch for each row of output, which points to the "current stop" that the dispatch is at. SELECT TOP 4 DispatchID, Min(StopNumber) AS NextStop, Arrived,

问题 I'm using this command to merge multiple identical directories and to remove duplicate lines from each of the corresponding files: for f in app1/*; do bn="$(basename "$f")" sort -u "$f" "app2/$bn" > "app/$bn" done Is there a way to edit this so that it checks the lines of all the files and removes all the duplicates as well? I do need to keep the existing file structure with individual files. The end result creates a directory with 300 text files that's no larger than 30mb. Example: *

问题 To begin with I have decided to post my code here so everyone can understand the issues I have with the code and will be able to assist me better. main.cpp #include <sstream> #include <iostream> #include <cstdlib> #include <string> #include "validate.h" #include "main.h" using namespace std; int main() { name = getName(); score = quiz(); cout << "\n\n"; system("pause"); return (0); } string getName() { cout << "Enter your name: "; getline(cin, name); val.set_item(name); valid = val.vName();

问题 Hi this is my first post here, sorry for my bad english. I'd like to see if all the age of one value are the same. If they is no duplicate or if the values are the same, then it's ok to me. In the example below, when it's "NOT OK", i'd like to copy my row, then paste it in another sheet (I can deal with this part ^^) ID Age My Value ------------------- 1 15 NOT OK 2 50 OK 2 50 OK 3 35 OK 1 16 NOT OK 1 15 NOT OK Thanks in advance 回答1: You can compare a COUNTIF that simply counts based on the

问题 I created a javascript function to copy data from an input on another jQuery tab to a Summary tab. I am having an issue with duplication with a dropdown. I need for it to replace the exisiting information when choosing another selection if a change is needed.

问题 As a policy, we do not update our documents, but we recreate with updated values. When I will process the events, I would like to keep only the updated ones, so I would like to filter items out of my RDD based on multiple values. For instance, say an item would be: { "name": "Sample", "someId": "123", "createdAt": "2016-09-21T02:16:32+00:00" } and when it is updated: { "name": "Sample-Updated", "someId": "123", # This remains the same "createdAt": "2016-09-21T03:16:32+00:00" # This is greater
