问题 I'm trying to export data to a csv file, as there are chinese characters in the data i had to use unicode.. but after adding the preamble for unicode, the commas are not recognized as delimiters and all data are now written to the first column. I'm not sure what is wrong. Below is my code which i wrote in a .ashx file. DataView priceQuery = (DataView)context.Session["priceQuery"]; String fundName = priceQuery.Table.Rows[0][0].ToString().Trim().Replace(' ', '_'); context.Response.Clear();

Export MySQL to CSV, some columns with quotes and some without

由 半世苍凉 提交于 2019-12-07 03:27:07
问题 I am exporting a MySQL table and I want to export the integer type columns without double quotes but the varchar type columns with double quotes. I need to do this to have the correct formatting for the next step in my work. Can this be done in MySQL? I know I could probably do this in a python script but the csv files are pretty large (>1 GB) so I think it might take awhile to do that. Anyway, is this possible using MySQL Queries? Here's my current export script format: SELECT 'column_name_1

Python/Numpy - Save Array with Column AND Row Titles

由 无人久伴 提交于 2019-12-06 23:49:09
问题 I want to save a 2D array to a CSV file with row and column "header" information (like a table). I know that I could use the header argument to numpy.savetxt to save the column names, but is there any easy way to also include some other array (or list) as the first column of data (like row titles)? Below is an example of how I currently do it. Is there a better way to include those row titles, perhaps some trick with savetxt I'm unaware of? import csv import numpy as np data = np.arange(12)

How to save Amazon Redshift output to local CSV through PSQL on SQL WorkBench?

由 拜拜、爱过 提交于 2019-12-06 22:38:46
问题 I am writing psql through Amazon Redshift and now I am trying to save the output as CSV through PSQL query, on SQL WorkBench The reason I am planning to do this through query instead of using select clause and then right click to save the output as csv, is because there are large amount of data, I found that if I generate the output into a temp table, it's much much faster than using select to display all the output. Therefore, I am thinking whether saving to local CSV can be faster too. I

Creating a CSV file from MySQL table using php

由 人盡茶涼 提交于 2019-12-06 17:18:00
问题 this code creates a csv file. However, I have avoided printing out commas in the fields because it is used as a delimeter (see line 22). Now I want to remove (carriage returns and new lines) from the fields. Adding $somecontent .= str_replace("\n", "", $val); on line 23 does not seem to work. any ideas? @chmod($export_csv, 0777); $fe = @fopen($export_csv."/export.csv", "w+"); if($fe){ $somecontent = ""; $fields_count = 0; // print field headers $db->query($sql_view); if($row = $db->fetchAssoc

I have an "Export to CSV" button that exports all car models. When I export all cars into CSV, the "features" (e.g. AM/FM Radio, Moon Roof, Leather Interior, Bluetooth, GPS etc..) column displays as the following: [<Feature: GPS>, <Feature: Leather>] How do I get rid of all that other stuff, and just have "GPS, Leather"? MODEL class Features(models.Model): name = models.CharField(max_length=20) def __unicode__(self): return self.name class Car(models.Model): model_name = models.CharField(max_length=20) features = models.ManyToManyField(features) def __unicode__(self): return self.model_name
