使用R从phpmyadmin连接到本地数据库 [英] Connect to a local database from phpmyadmin with R
问题描述
我已经搜索了很多线程来解释与具有R的数据库的连接，但是我仍然无法使其正常工作.
I have searched for a lot of threads explaining the connexion with a database with R but I still can't make it work.
此刻，我知道我必须安装软件包'ROBDC'并使用odbcConnect()或odbcDriverConnect().但是第一个似乎更困难，因为我必须设置OBDC连接(尝试了一些操作，但在t.t上却无法正常工作).
At the moment, I know that I have to install the package 'ROBDC' and use either odbcConnect() or odbcDriverConnect(). But the first one seems harder since I have to set an OBDC connection (tried some things but didn't work too t.t).
我的最终目标是在位于Web服务器上的数据库中提取一些数据，但是，首先，我想了解这些功能如何用于使用Wamp Server创建的本地数据库.我目前正在Windows 7上工作.
My final goal is to extract some data in a database located in a web server but, first, I wanted to see how the functions work for a local database created with Wamp Server. I'm currently working on Windows 7.
我的数据库的名称是'extraction'，而id是'root'(通常没有密码)，所以我写道:
My database's name is 'extraction' and the id is 'root' (no pwd, usually) so I wrote :
install.packages('RODBC',repos="http://cran.rstudio.com/")
odbcDriverConnect(Driver='mysql'; Server=localhost;
Database=extraction; Uid='root'; pwd='')
我不知道语法是否正确，我已经尝试了很多并且总是遇到相同的错误，无法获得驱动程序和数据源.
I don't know if the syntax is correct, I have tried a lot and always the same error with drivers and data source unobtainable.
这里是完整的消息(以法语对不起，D:)
Here the full message (in French sorry D:)
"[[RODBC]错误:状态IM002，代码0，消息[Microsoft] [飞行员ODBC语法]无法解释的源代码和非专家术语"
"[RODBC] ERROR: state IM002, code 0, message [Microsoft][Gestionnaire de pilotes ODBC] Source de données introuvable et nom de pilote non spécifié"
我使用此功能来避免obdcConnect()所需的dns事情，但是我仍然不知道我是否在做正确的事情(显然不是因为他不工作:D)，但这是我第一次尝试使用R与数据库进行交互，因此即使我一直在寻找所有帮助，我也不知道该去哪里.
I used this function to avoid the dns thing required for obdcConnect() but still I don't know if I'm doing the right thing (obvsly not since he doesn't work :D) but it's my first time trying with R to interact with databases so I don't know where to go even with all the help I have looked for.
谢谢.
推荐答案
好吧，我找到了一个名为RMySQL的程序包
Well, I found a solution with a package called RMySQL
install.packages('RMySQL')
require(RMySQL) #if already installed
con <- dbConnect(RMySQL::MySQL(), host = "localhost",dbname="extraction",user = "root", password = "")
test_extraction <- dbReadTable(con, "utilisateurs") #utilisateurs is a table from my database called extraction
