| For 2023 (and 2024 ...) - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk. Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active! I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |

MySQL database from Ruby - an example
Both MySQL and Ruby are huge subjects - the former being an excellent database engine and the latter a superb programming language. Yet although each individually is a huge subject, linking the two (i.e. accessing data stored in a MySQL database via a Ruby program) is so each that it's almost trivial. Here's one way of doing it - my "Hello MySQL in Ruby" if you like. 1. Download the Ruby/MySQL module from http://www.tmtm.org/en/ruby/mysql/ 2. Add the following lines (or equivalent) into your code: require "mysql"3. Enjoy! The code loads in the module that you've downloaded (require), connects to the database engine and database (Mysql::new), runs the query (the query method on the connection object) and iterates through the result set. The full source code of this example is here, and we cover the topic on our Ruby Programming course.
