    <p>I have two tables, that relate via a one-to-many relationship i.e </p> <pre><code>tableOne (1)----------(*) tableTwo </code></pre> <p>Given the basic schema below</p> <pre><code>tableOne { groupID int PK, groupTitle varchar } </code></pre> <p>and</p> <pre><code>tableTwo { bidID int PK, groupID int FK } </code></pre> <p>Consider the two tables yield the following record-set based on joining the tables on the <code>tableOne.groupID = tableTwo.groupID,</code></p> <pre><code>tableOne.groupID | tableOne.groupTitle | tableTwo.bidID | tableTwo.groupID ________________________________________________________________________________ 1 | Physics Group | 1 | 1 2 | Chemistry Group | 2 | 2 2 | Chemistry Group | 3 | 2 1 | Physics Group | 4 | 1 </code></pre> <p>I would like to list such a record-set in an HTML table as follows: </p> <pre><code>tableOne.groupID | tableOne.groupTitle | tableTwo.bidID | tableTwo.groupID ________________________________________________________________________________ 1 | Physics Group | 1 | 1 | Physics Group | 4 | 1 2 | Chemistry Group | 2 | 2 | Chemistry Group | 3 | 2 </code></pre> <p>I'm interested in finding out if this can be done in SQL, or alternatively finding out ways of listing such a record-set in HTML using good standards.</p> <p>The solution that comes to mind is simply iterating through the record-set and leveraging a sentinel to list all records with the same <code>tableOne.groupID</code> grouped in a single row <code>&lt;tr&gt;</code> - and also listing <code>tableOne.groupID</code>s once as a unique identifier of that record-group. However I don't want to go down that path as I would like to avoid mixing code with HTML if possible.</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.
