    <p>You don't specify the id (or key column) in your ON DUPLICATE KEY UPDATE clause.</p> <p>From: <a href="http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html" rel="nofollow">http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html</a></p> <blockquote> <p>For example, if column a is declared as UNIQUE and contains the value 1, the following two statements have identical effect:</p> <blockquote> <p>INSERT INTO table (a,b,c) VALUES (1,2,3) ON DUPLICATE KEY UPDATE c=c+1;</p> <p>UPDATE table SET c=c+1 WHERE a=1;</p> </blockquote> </blockquote> <p>What you currently have is most likely changing the last row you inserted into the database and not the duplicate key row. Read the docs on LAST_INSERT_ID(): <a href="http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_last-insert-id" rel="nofollow">http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_last-insert-id</a></p> <p>Looking back at your question, I know I'm not really/fully answering your question. I'm partially trying to understand what the use case is. In cases where I'm creating a user through code, if it is the admin creating a user, I just set the account active (and set the activated column if there is one). If it is a user creating an account through a web form, they get set as pending until they use the link in their email. The link in the email uses an activation code that allows me to do something like: </p> <pre><code>update user set status='active' activated=NOW() where code=:activation_code </code></pre>

    1. COActually, the "id=LAST_INSERT_ID(id)" part is there on purpose, it makes sure I can retrieve the id of the updated row. (which is also described in the mysql documentation)

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.
