    <p>Jacob Quinn here, package maintainer for the ODBC package for Julia.</p> <p>A few things to help you understand how the process works:</p> <p>-ODBC is an API middle layer originally developed by Microsoft to create a common interface between DB systems and applications. This was useful because with the number of different DB systems, it would be hard to have applications that could reliably connect to any DB.</p> <p>-ODBC has been ported to Linux/Unix/OSX systems through 2 main projects: iodbc (mainly OSX) and unixODBC (Linux)</p> <p>-The basic components of the API are the ODBC Manager, which is the middle layer, the DB system, the application, and the ODBC <em>driver</em>, which is DB-specific and actually implements the communication between application-ODBC Manager and ODBC Manager-DB system.</p> <p>-In the case of RMySQL, only the MySQL driver has been implemented with R wrapper functions which allow the connection to MySQL DB systems</p> <p>-In the case of ODBC.jl (and the corresponding RODBC for R), a more generalized approach is taken where wrapper functions of the ODBC Manager are provided, which allow connection with <em>any</em> DB system, provided the user has the correct DB driver installed and connection string</p> <p>Hopefully that helps understand the ODBC process a little better.</p> <p>So for your case, it looks like you don't have the MySQL driver installed since it didn't show up in your ODBC Manager. You can find the driver <a href="http://dev.mysql.com/downloads/connector/odbc/#downloads" rel="noreferrer">here</a>. </p> <p>Once you have the driver installed, it should be pretty simple to set up a DSN (following either MySQL documentation or the excellent connectionstrings.com, <a href="http://www.connectionstrings.com/mysql-connector-odbc-5-1/" rel="noreferrer">MySQL Section</a>).</p> <p>You should then be able to start using ODBC in julia:</p> <pre><code>Pkg.add("ODBC") using ODBC ODBC.connect(dsn) query("select * from customers") </code></pre> <p>If you run into any other issues or troubles getting things setup or installed, feel free to open an issue <a href="https://github.com/karbarcca/ODBC.jl/issues?state=open" rel="noreferrer">here</a> and I'm more than willing to help troubleshoot the setup to get you going.</p>

    1. COThanks a lot for the great explanation. I think I installed the required driver successfully, but when I tried to run the commands you wrote in above, I still got an error `[ODBC] 08S01: [MySQL][ODBC 5.2(w) Driver]Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)`. I'm sure this happened because I originally installed and used MySQL via MAMP, where the default path of the socket is `/Applications/MAMP/tmp/mysql/mysql.sock`, instead of `/tmp/mysql.sock`. However, I don't understand where and how I can tell the correct socket path to the driver or function...

    2. COYou might be missing a [client] section in your /etc/my.cnf. Add (or modify) the socket key key under that section with something like "socket=/var/lib/mysql/mysql.sock". HTH.

    3. COI already modified that section as `socket = /Applications/MAMP/tmp/mysql/mysql.sock` in `/Applications/MAMP/conf/my.cnf`, but isn't it sufficient? Or do I have to create `/etc/my.cnf`? (which I don't have right now)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
