Hi,

This patch makes Oracle a supported database for SQL source code
blocks:

  - separate or unified logins, take your pick of:
    :dbuser user :dbpassword password :dbhost connect_id
    :dbuser user/password@connect_id
    :cmdline user/password@connect_id

  - support for :colnames on/off

  - helpful error messages in minibuffer if execution fails

  - good looking result block (most of the time)

I've tested this extensively on Windows 7. It only needs the sqlplus
executable and < > file redirection, so it should work everywhere.

I am willing to execute an FSF copyright assignment.

Regards,
John
