Body
asset_property table: <pre><code>| asset_id | property_id | property_value | |:--------:|:-----------:|:---------------| | 146 | 1 | 4G | | 146 | 3 | 68723-239Gs | | 147 | 1 | A7 | </code></pre> This is my query: <pre><code>INSERT INTO asset_property (asset_id, property_id, property_value) VALUES (146, 1, '4G'), (146, 2, 'Black & Decker'), (146, 3, ''), ON DUPLICATE KEY UPDATE property_value = VALUES(property_value); </code></pre> Is there a way to say something like this: <pre><code>INSERT INTO asset_property (asset_id, property_id, property_value) VALUES (146, 1, '4G'), (146, 2, 'Black & Decker'), (146, 3, ''), ON DUPLICATE KEY UPDATE property_value = VALUES(property_value) ON VALUES(property_value) IS NULL DELETE FROM asset_property WHERE asset_id = VALUES(asset_id) AND property_id = VALUES(property_id); </code></pre> Or I could use PHP to determine empty <code>property_value</code> sets and build a second query. So I would need this: <pre><code>DELETE FROM asset_property WHERE 'PRIMARY KEY' IN ('146-3'); </code></pre> The syntax is okay, but 0 rows are affected. I've tried this: <pre><code>SELECT 'PRIMARY KEY' FROM asset_property WHERE asset_id = 146; </code></pre> But the result is: <pre><code>| PRIMARY KEY | |:------------| | PRIMARY KEY | | PRIMARY KEY | </code></pre> The <a href="http://dev.mysql.com/doc/refman/4.1/en/multiple-column-indexes.html" rel="nofollow">MySQL Manual</a> seams to say you can't.

Guidance

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.
