如何在 Julia 中连接到 MySQL 数据库 [英] How to connect to MySQL database in Julia

问题描述

我是 Julia 的新手，过去几年一直使用 R，我正在努力完成我的第一个任务，即连接到我的 AWS MySQL 数据库.

I am new to Julia having used R for the last few years and I am struggling with my first task which is connecting to my AWS MySQL database.

我学习了许多在线教程，但无论我做什么，我都会收到相同的信息.

I have followed many online tutorials but I get the same message no matter what I do.

所有东西都是昨天安装的，所以应该都是当前版本.

Everything was installed yesterday so it should all be the current version.

julia-version = 版本 1.5.2

julia-version = Version 1.5.2

代码如下:

Pkg.add(PackageSpec(url="https://github.com/JuliaComputing/MySQL.jl"))
Pkg.add(PackageSpec(url="https://github.com/JuliaDB/DBI.jl"))

using MySQL
con = MySQL.connect("ec2blah.eu-west-2.compute.amazonaws.com", "name", "password", db = "database")

当我运行它时，我收到以下错误:

When I run this I get the following error:

UndefVarError: connect not defined
getproperty(::Module, ::Symbol) at Base.jl:26
top-level scope at data_prep.jl:18

谢谢

推荐答案

根据 文档，你可能应该这样做:

As per the documentation, you should probably do something like this:

using Pkg
Pkg.add("MySQL")       # No need for a full PackageSpec here
Pkg.add("DBInterface")

using MySQL
using DBInterface
conn = DBInterface.connect(MySQL.Connection, "ec2blah.eu-west-2.compute.amazonaws.com",
                           "name", "password", db = "database")
