    <p>Check the <a href="https://www.doctrine-project.org/projects/doctrine-orm/en/2.6/reference/basic-mapping.html#identifiers-primary-keys" rel="nofollow noreferrer">latest doctrine documentation</a></p> <p>Here is a summary : the list of possible generation strategies:</p> <p><strong>AUTO (default)</strong>: Tells Doctrine to pick the strategy that is preferred by the used database platform. The preferred strategies are <code>IDENTITY</code> for MySQL, SQLite and MsSQL and <code>SEQUENCE</code> for Oracle and PostgreSQL. This strategy provides full portability.</p> <p><strong>SEQUENCE:</strong> Tells Doctrine to use a database sequence for <code>ID</code> generation. This strategy does currently not provide full portability. Sequences are supported by Oracle and PostgreSql.</p> <p><strong>IDENTITY:</strong> Tells Doctrine to use special identity columns in the database that generate a value on insertion of a row. This strategy does currently not provide full portability and is supported by the following platforms: </p> <ul> <li>MySQL/SQLite => <code>AUTO_INCREMENT</code></li> <li>MSSQL => <code>IDENTITY</code> </li> <li>PostgreSQL => <code>SERIAL</code></li> </ul> <p><strong>TABLE:</strong> Tells Doctrine to use a separate table for <code>ID</code> generation. This strategy provides full portability. <em>This strategy is not yet implemented!</em></p> <p><strong>NONE:</strong> Tells Doctrine that the identifiers are assigned, and thus generated, by your code. The assignment must take place before a new entity is passed to EntityManager#persist. <code>NONE</code> is the same as leaving off the <code>@GeneratedValue</code> entirely.</p> <h3>SINCE VERSION 2.3 :</h3> <p><strong>UUID:</strong> Tells Doctrine to use the built-in Universally Unique Identifier generator. This strategy provides full portability.</p>

    1. COYou referenced 2.0 doc, so I guess table is available now.. I still wonder about UUID if you have any idea.

    2. COI never use this kind of generator id with doctrine 2. All i can say, it's that if your database support UUID generation, you will able to use this feature. It's interesting only for distributed systems. With Oracle Database it will generate an ID thanks to the SYS_GUID() oracle command. It's done by the Doctrine DBAL layer. And you're right Table generator is available now in the current version of doctrine.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
