    <p>There is no problem querying tables from different databases. </p> <pre><code>SELECT a.*, b.* FROM db1.table1 a INNER JOIN db2.table2 b ON (a.id = b.id) </code></pre> <p>Will run with no problems, as will your insert query.<br> <strong>However</strong> the user that starts the query needs to have proper access to the databases and tables involved. </p> <p>That means that user1 (who does the insert) has to be <code>grant</code>ed insert+select rights to table <code>{$joomla_db}.jos_muscol_artists</code> and select rights to <code>{$sam_db}.songlist</code></p> <p>If you don't want to expand the rights of your existing users, then you can just create a new <code>inserter</code> user that has the proper access rights to use both databases in the proper manner.<br> Only use this user to do inserts. </p> <p><strong>Alternative solution without adding users</strong><br> Another option is to create a blackhole table on db1 (the db you select from) </p> <pre><code>CREATE TABLE db1.bh_insert_into_db2 ( f1 integer, f2 varchar(255), f3 varchar(255) ) ENGINE = BLACKHOLE; </code></pre> <p>And attach a trigger to that that does the insert into db2.</p> <pre><code>DELIMITER $$ CREATE TRIGGER ai_bh_insert_into_db2_each ON bh_insert_into_db2 FOR EACH ROW BEGIN INSERT INTO db2.table2 (f1,f2,f3) VALUES (NEW.f1, NEW.f2, NEW.f3); END $$ DELIMITER ; </code></pre> <p>The insert into table <code>db2.table2</code> will happen with the access rights of the user how created the trigger. </p> <p><a href="http://dev.mysql.com/doc/refman/5.1/en/grant.html" rel="nofollow">http://dev.mysql.com/doc/refman/5.1/en/grant.html</a></p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
