I'm trying to display a tree structure in MYSQL with this reference (<a href="http://mikehillyer.com/articles/managing-hierarchical-data-in-mysql/" rel="nofollow">http://mikehillyer.com/articles/managing-hierarchical-data-in-mysql/</a>) and I'm seeing that only works with 1 parent in same table. If you have another table to join with, nothing go well. Example: Table Menu: <pre><code>+----+--------+-------+ | id | name | order | | 1 | Father | 0 | | 2 | Father | 1 | | 3 | Son | 0 | | 4 | Child | 1 | | 5 | Granson| 2 | +----+--------+-------+ </code></pre> Table Relations <pre><code>+----+---------+-----------+ | id | menu_id | parent_id | | 1 | 1 | NULL | | 2 | 2 | NULL | | 3 | 3 | 1 | | 4 | 4 | 3 | | 5 | 5 | 4 | +----+---------+-----------+ </code></pre> Do the SELECT <pre><code>SELECT child_menu.*, menu.* FROM menu, relations AS child_menu WHERE menu.id = child_menu.menu_id GROUP BY menu_id </code></pre> I Have this: <pre><code>+----+--------+-------+ | id | name | order | | 1 | Father | 0 | | 2 | Father | 1 | | 3 | Son | 0 | | 4 | Child | 1 | | 5 | Granson| 2 | +----+--------+-------+ </code></pre> I'm trying to leave their children in order in the same SELECT. From what I see in the examples, only works if the parent is in the same table. Can someone help me? thank you Edited: EXPECTED OUTPUT: <pre><code>+----+--------+-------+ | id | name | order | | 1 | Father | 0 | | 3 | Son | 0 | | 4 | Child | 1 | | 5 | Granson| 2 | | 2 | Father | 1 | +----+--------+-------+ I.E. Father Son Child Grandson </code></pre>

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.
