    <p>I am having a problem where I am getting duplicated values from what I think I should be getting.</p> <p>here is my sql:</p> <pre><code> SELECT DISTINCT p.products_image, pd.products_name, p.products_id, p.products_model, p.manufacturers_id, m.manufacturers_name, p.products_price, p.products_sort_order, p.products_tax_class_id, pd.products_viewed, group_concat(p2i.icons_id separator ",") AS icon_ids, group_concat(pi.icon_class separator ",") AS icon_class, IF(s.status, s.specials_new_products_price, NULL) AS specials_new_products_price, IF(s.status, s.specials_new_products_price, p.products_price) AS final_price FROM products p LEFT JOIN specials s ON p.products_id = s.products_id LEFT JOIN manufacturers m ON p.manufacturers_id = m.manufacturers_id JOIN products_description pd ON p.products_id = pd.products_id JOIN products_to_categories p2c ON p.products_id = p2c.products_id INNER JOIN products_specifications ps7 ON p.products_id = ps7.products_id LEFT JOIN products_to_icon p2i ON p.products_id = p2i.products_id LEFT JOIN products_icons pi ON p2i.icons_id = pi.icons_id WHERE p.products_status = '1' AND pd.language_id = '1' AND ps7.specification IN ('Polycotton' , 'Reflective') AND ps7.specifications_id = '7' AND ps7.language_id = '1' AND p2c.categories_id = '21' GROUP BY p.products_id ORDER BY p.products_sort_order </code></pre> <p>The column that is getting double values is icon_ids from the group concact. This seams to happen only if ploycotton, and reflective are both IN ps7.specification. </p> <p>If it is only one or the other then it works fine.</p> <p>The products_to_icon table contains 2 columns, products_id and icons_id. </p> <p>If a product has 2 icons, there are 2 rows so I'm pretty sure it is this fact that is causing the duplicate icons ids. </p> <p>When I run this, the icon_ids column for a product with 2 icons is "4,4,6,6" for example, when what I need is "4,6"</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.
