export-to-csv

问题 I am trying count the rows containing values in a bunch of CSV in a folder. I managed to get the code to count it but I can't seem to find a way to export the results to a CSV. All I got is a blank CSV. What am I missing here? $FOLDER_ROOT = "C:\Test\2019" $OUTPUT_CSV = "C:\Test\2019\Count.csv" Get-ChildItem $FOLDER_ROOT -re -in "*.csv" | ForEach-Object { $filestats = Get-Content $_.Fullname | Measure-Object -Line $linesInFile = $filestats.Lines - 1 Write-Host "$_,$linesInFile" } | Export-Csv

问题 Currently, I am using Go to access my database. Ideally, I'd like to generate .csv based on the table's name and export data to those files based on the query. For example, if I ran: select t1.*,t2.* from table1 t1 inner join table2 t2 on t2.table_1_id = t1.id where t1.linking_id = 22 I'd like a .csv file generated for both table 1 and table 2 where data from each table would generate and then export into these two generated files with the same names as the table's names. I know in PHP I can

问题 I have a large number of html tables that I'd like to convert into CSV. Pasting individual tables into excel and saving them as .csv works, as does pasting the html tables into simple online converters. But I have thousands of individual tables, so I need a script that can automate the conversion process. I was wondering if anyone has any suggestions as to how I could go about doing this? Python is the only language I have a decent knowledge of, so some sort of python script would be ideal. I
