Rails2.2.2 on the adapter to install mysql

Gem install mysql on Rails2.2.2

Environment: WindowsXP RadRails ruby1.8.2 rails2.2.2 mysql5.1.30

click google and found Rails2.2.2 database does not include the mysql adapter, needs its own installation.

The first attempt to directly run

gem install mysql

Agent has found a corporate network can not be remote installation, the local installation to find the corresponding gem has no library, but to then try again.

Then, try to install mysql's jdbc adapter.

Start up http://gems.rubyforge.vm.bytemark.co.uk/gems/ download

activerecord-jdbc-adapter-0.9.gem ,

jdbc-mysql-5.0.4.gem ,

activerecord-jdbcmysql-adapter-0.9.gem .

Run

gem install E:\study\Ruby_on_Rails\ruby-gems\activerecord-jdbcmysql-adapter-0.9.gem
gem install E:\study\Ruby_on_Rails\ruby-gems\activerecord-jdbc-adapter-0.9.gem

At this point I found myself on the wrong one to start, there is no clear environment parroting the installation database adapter. (This is also a common problem for some articles online, on account of some relevant things unclear, accidentally on the Road, a)

Commands out of sync in client error

If you are in your client code to be Commands out of sync; You can't run this command now, you are in the wrong order of client function calls!

This may happen, for example, if you are using mysql_use_result() and you have to call the mysql_free_result() before trying to implement the new query. If you or mysql_use_result() between mysql_store_result() trying to return data on the implementation of two inquiries, it may also happen.

Errors found at places mysql_adapter.rb: 414, code

    def tables(name = nil) #:nodoc:
        tables = []
        execute("SHOW TABLES", name).each { |field| tables << field[0] } #414 Line  
        tables
      end

Why get this wrong? Guess is that mysql libraries do not match, put the previous% MYSQL_HOME% / bin libmySQL.dll available to the system under the Copy% RUBY_HOME% / bin directory, according to speculation, with InstantRails-2.0-win.zip under libmySQL.dll available to the system replacement, re-run db: migrate, really all ok.

Might well be described as full of twists and turns of its people!
