mysql-python

问题 I just solved some problems in my Django 1.3 app by using PyMySQL instead of MySQLdb. I followed this tutorial on how to make the switch: http://web-eng-help.blogspot.com/2010/09/install-mysql-5-for-python-26-and.html Now I want to know what PyMySQL actually is and how it is different from MySQLdb. I am using it on localhost and will then upload it to some hosting. Is it fine to use PyMySQL on localhost and on hosting whatever they provide? Since I have changed "MySQLdb" in base.py and

问题 I can connect to my local mysql database from python, and I can create, select from, and insert individual rows. My question is: can I directly instruct mysqldb to take an entire dataframe and insert it into an existing table, or do I need to iterate over the rows? In either case, what would the python script look like for a very simple table with ID and two data columns, and a matching dataframe? 回答1: Update: There is now a to_sql method, which is the preferred way to do this, rather than

问题 I have a program that is exporting MSSQL data and importing it into MySQL. I have a function that is importing as follows: def importMySql (mycursor,exportedfilename,table,delimiter): file_loc = str(sys.path[0] +"\\" +exportedfilename.lower()+".out").replace("\\", "\\\\") mycursor.execute("LOAD DATA LOCAL INFILE '%s' INTO TABLE %s FIELDS TERMINATED BY '%s' LINES TERMINATED BY '\r\n'" %(str(file_loc), table, delimiter)) the cursor (MySQLdb) is raising the following warnings: C:\Users\tfy

问题 This post is the same with my question in MySQL in Python: UnicodeEncodeError: 'ascii' this is just to clear things up. I am trying to save a string to a MySQL database but I get an error: File ".smart.py", line 51, in (number, text, 'smart', 'u') UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 25: ordinal not in range(128) and the string is saved at m['Text'] Lala*=#&%@<>_?!:;-'"/()¥¡¿ Here is a snippet to the code risk = m['Text'] msg = risk.encode('utf8') text = db

问题 I have a very weird problem with mysqldb (mysql module for python). I have a file with queries for inserting records in tables. If I call the functions from the file, it works just fine; but when trying to call one of the functions from another file it throws me a _mysql_exception.InterfaceError: (0, '') I really don't get what I'm doing wrong here.. I call the function from buildDB.py : import create create.newFormat("HD", 0,0,0) The function newFormat(..) is in create.py (imported) : from

问题 This question already has answers here : Python sqlite3 parameterized drop table (1 answer) How do I use SQL parameters with python? (1 answer) Closed last year . So i use flask_mysqldb in a Flask(Python website) I'm trying to write a function to delete a row in any table. It works perfectly when I hardcode the tablename, but what do I need to do to be able to use a variable instead? @app.route('/delete/<string:table>/<string:id>', methods=['POST']) @is_logged_in def delete(table, id): #

问题 I've installed the flask-mysqldb module with pip package management system on my Windows machine and I don't know how to run it. I have tried to add the path to the MySQLdb in System properties and still nothing. 回答1: When I work with Flask and MySQL in Windows, I use XAMPP that includes MariaDB, PHP, and Perl. I run the XAMPP server and start MySQL service. I use Flask-MySQL which can be installed using pip install Flask-MySQL . Then I create database from phpMyAdmin which comes with XAMPP .

问题 I'm trying to start a django server and I'm getting an error I don't understand. This is the error at the bottom of the terminal output: django.db.utils.OperationalError: (2026, 'SSL connection error: error:00000001:lib(0):func(0):reason(1)') This: Error Loading MySQLdb Module and "pip install MySQLdb" Is a question I asked earlier that gives some background. I'm really new to Django and python and I saw this: mysql ERROR 2026 (HY000): SSL connection error: error:00000001:lib(0):func(0)
