    <p>Let's say I have a class <code>Article</code> which is automatically mapped by Java Ebean as a database table.</p> <p>For this table I wanted to retrieve entries via a <code>RawSql</code> query, because I find SQL more simple when it gets to complex queries with many joins and such. By far I have managed to give my SQL statement to the Parser. The query is correct, I already checked that.</p> <p>The only problem is, that I don't know, how to map the database results to my <code>Article</code> class. I know, that there is a <code>columnMapping(...)</code> method but honestly, I am to lazy to map every single column manually...</p> <p>Isn't there another way to just like <code>myResults.mapToClass(Article.class)</code> to retrieve something like a <code>List&lt;Article&gt;</code>?</p> <p>This is the code I already have:</p> <pre><code>Finder&lt;String, Article&gt; find = new Finder&lt;String, Article&gt;( String.class, Article.class); String sql = "SELECT * FROM article [...]"; RawSql rawSql = RawSqlBuilder.parse(sql).create(); List&lt;Article&gt; returnList = find.setRawSql(rawSql).findList(); </code></pre> <p>Alternatively:</p> <pre><code>Finder&lt;String, Article&gt; find = new Finder&lt;String, Article&gt;( String.class, Article.class); String sql = "SELECT id, title, sub_title FROM article [...]"; RawSql rawSql = RawSqlBuilder.parse(sql) .columnMapping("id", "id") .columnMapping("title", "title") .columnMapping("sub_title", "subTitle") .create(); List&lt;Article&gt; resultList = find.setRawSql(rawSql).findList(); </code></pre>

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.
