    <p>I am using CodeIgniter. My database is MySQL 5. The SQL statement below works fine, but I am thinking it would not really be compatible with MSSQL, PG, et al. I am wondering if it's possible to implement the statement using the Active Record class in CI, hence making it completely cross database ?</p> <p>I think the "GROUP_CONCAT" is where I'll fall down...</p> <p>EDIT - Found on the CodeIgniter board</p> <blockquote> <p>"It should be noted, however, that CONCAT is database specific. It’s not actually a part of the active record library, although I’m sure it’s supported by most, if not all database engines."</p> </blockquote> <p>I may have to rethink this, as it looks to be not possible using pure Active Record.</p> <pre><code>SELECT system.system_id, system.uuid, system.hostname, system.man_description, system.man_ip_address, system.os_short_name, system.os_full_name, system.man_type, system.man_icon, GROUP_CONCAT(DISTINCT '&lt;a href="', oa_group.group_id, '"&gt;', oa_group.group_description, '&lt;/a&gt;' ORDER BY group_description SEPARATOR ', ') as tag FROM system, oa_group, oa_group_sys WHERE system.system_id IN ( SELECT system.system_id FROM system, oa_group_sys, oa_group, oa_group_user WHERE system.man_status = 'production' AND system.system_id = oa_group_sys.system_id AND oa_group_sys.group_id = oa_group.group_id AND oa_group.group_id = oa_group_user.group_id AND oa_group_user.user_id = '1' ) AND system.system_id = oa_group_sys.system_id AND oa_group_sys.group_id = oa_group.group_id GROUP BY system.system_id </code></pre>

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.
