Mongodb: upsert multiple documents at the same time (with key like $in)

由 落花浮王杯 提交于 2021-01-29 18:38:25
问题 I stumbled upon a funny behavior in MongoDB: When I run: db.getCollection("words").update({ word: { $in: ["nico11"] } }, { $inc: { nbHits: 1 } }, { multi: 1, upsert: 1 }) it will create "nico11" if it doesn't exist, and increase nbHits by 1 (as expected). However, when I run: db.getCollection("words").update({ word: { $in: ["nico10", "nico11", "nico12"] } }, { $inc: { nbHits: 1 } }, { multi: 1, upsert: 1 }) it will correctly update the keys that are already in the DB, but not insert the

Using xlswrite I can only add in rows at the end of the file or replace some rows. EDIT 1: I have another set of file in which the index is

Write to MS Access table, python win32com

问题 I'm playing around with win32com.client for python to try to write/insert a row to a MS Access table. I've found an example of how to connect and query an Access table here. Basically, their code slightly modified for my own use is: import win32com.client connection = win32com.client.Dispatch(r'ADODB.Connection') DSN = 'PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=c:\\testdb.mdb;' connection.Open(DSN) recordset = win32com.client.Dispatch(r'ADODB.Recordset') recordset.Open('SELECT * FROM

My Python code is only selecting half of a list's contents?

由 廉价感情. 提交于 2021-01-28 20:57:57
问题 I'm very new to Python, and I'm going through some example projects I found online but I'm stuck on my palindrome checker at the moment. Right now, my code takes a word as an input, splits it in half, saves each part into separate variables, makes both of the variables lists, and from there it SHOULD reverse the second list so I can compare it to the first, but from what I've gathered trying to fix it, it's only appending half of the selection to the new list. For example, if I enter "racecar
