copy

问题 I have two tables with the same column anomaly_id . I want to copy the row of anomaly_id from the first table to the second table using this code UPDATE amb.anamoly_log_update SET anamoly_id = t2.anomaly_id FROM amb.anamoly_log_update t1 INNER JOIN amb.anomaly_fee t2 ON t1.anamoly_id=t2.anomaly_id Even after I did that it shows 0 rows affected, when there is data in amb.anomaly.fee (source table) Please help Edit: Comment from post: I just want to copy all the anamoly_id from amb.anamoly_fee

问题 So I have been banging my head over this seemingly insignificant issue. I don't necessarily know what to search for. I have scoured around for solutions. I need to make a copy of 2D array. The array consists of objects (a class I created call Cell), but the as soon as I make a copy I store that copy into a hash map (for possible reference later), then continue to modify the original array. The issue is that the modifications to the original also affect the copy now in the hash map.

问题 I have a text file named 1.txt which contains the following: 123456 011111 02222 03333 and I have created a python code which copy the first line to x number of folders to file number.txt then copy the second to x number of folders: progs = int(raw_input( "Folders Number : ")) with open('1.txt', 'r') as f: progs2 = f.read().splitlines() progs3 = int(raw_input( "Copy time for each line : ")) for i in xrange(progs): splis = int(math.ceil(float(progs)/len(progs3))) with open("{0}/number.txt"

问题 I have to make a very large number of simulations on a R*C grid. These simulations are altering the grid, so I need to copy my reference grid before each, and then apply my simulating function on the fresh new grid. What is the fastest way to do this in Python? Since I have not found a similar question on StackOverflow, I did the tests myself and decided to post them here thinking they could be useful to other people. The answer will be a community response so that other people can add new

问题 I am trying to copy a range of cells from a range of rows from two workbooks. This information is used to do a comparison of the contents of both workbooks rows by ID. The first solution I tried involved cell by cell "binary" comparison. This works for worksheets with few rows: For i = 2 To LastSheetRow Set FoundCell = Workbooks(WorkbookA).Sheets(SheetNameFromArray).Range("A:A").Find(What:=Workbooks(WorkbookB).Sheets(SheetNameFromArray).Cells(i, 1).Value) If Not FoundCell Is Nothing Then

问题 I receive an array as a pointer from a function and want to initialize a QVector from that. For now I do it like this: void foo(double* receivedArray, size_t size) { QVector<double> vec(size); std::copy(receivedArray, receivedArray + size, std::begin(vec)); } Would it be equally possible to do this: void foo(double* receivedArray, size_t size) { QVector<double> vec(size); vec.data() = receivedArray; } Would this break some kind of Qt mechanism that I am not aware of? 回答1: The first one does

问题 As the topic, this is the code and there is no error message but data did not get insert. This is my code, and can anyone tell me what's wrong with it? import psycopg2 import sys import os import glob import csv #open the csv folder dictfile='******' os.chdir(dictfile) total=[] for file in glob.glob("*.csv"): total.append(file) con = None try: con = psycopg2.connect(host='localhost',database='*****',user='postgres', password='*****') cur = con.cursor() for i in range(0,1): filename='/Users

问题 I have a function which processes and stores a lot of data in it and then it returns the results as a vector of class. The amount of data stored in this function is tremendous and I want to clear the storage memory of the function after it finished its job. Is it necessary to do so (does the function automatically clear the memory) or should I clear the memory by some function? Update: vector<customers> process(char* const *filename, vector<int> ID) { vector<customers> list_of_customers;

问题 I am trying to copy every 30th file from one folder to another and automate the process for other folders. I have already tried the batch script in this thread: windows batch file script to copy every tenth file from a folder to another folder and just get "The syntax in that command is incorrect" when I run the file (and yes, I've tried both versions). My folders do have spaces in the names (not my choice and cannot be changed). The files are named image00000X.jpg and yes, there are over

问题 How would you copy several directories to a destination directory in docker? I do not want to copy the directory contents , but the whole directory structure. The COPY and ADD commands copy the directory contents, flattening the structure, which I do not want. That is, if these are my sources: . ├── a │ ├── aaa.txt │ └── uuu.txt ├── b │ ├── ooo.txt │ └── ppp.txt └── c └── jjj.txt I want this to be deployed to the docker image: code/ ├── a │ ├── aaa.txt │ └── uuu.txt ├── b │ ├── ooo.txt │ └──
