What you're doing here is unnecessary thanks to <a href="http://dev.mysql.com/doc/refman/5.0/en/example-auto-increment.html" rel="nofollow"><code>AUTO_INCREMENT</code></a> in mysql. Run this command from PhpMyAdmin (or another DB management system): <pre><code>ALTER TABLE db MODIFY COLUMN ID INT NOT NULL AUTO_INCREMENT; </code></pre> Now when insert a row into <code>db</code> mysql will assign the ID for you: <pre><code>INSERT INTO db (id, column1, column2) VALUES(NULL, 'abc', 'def'); </code></pre> <code>SELECT * FROM db;</code>: <pre><code>+--+-------+-------+ |id|column1|column2| +--+-------+-------+ |1 |old |oldrow | +--+-------+-------+ |2 |abc |def | <--- Your newly inserted row, with unique ID +--+-------+-------+ </code></pre> If you delete a row, it is true that there will be an inconsistency in the order of the ID's, but this is ok. IDs are not intended to denote the numeric position of a row in a table. They are intended to uniquely identify each row so that you can perform actions on it and reference it from other tables with foreign keys. <hr> Also if you need to grab a group of ID's (stored in an array, for example), it is much more efficient to perform one query with an <code>IN</code> statement. <pre><code>$ids = array(1,2,3,4,5,6); $in = implode(',', $ids); mysql_query('SELECT * FROM db WHERE id IN ('.$in.')'); </code></pre> However, if you want all rows just use: <pre><code>SELECT * FROM dbs; </code></pre> But be weary of <a href="http://bobby-tables.com/" rel="nofollow">bobby tables</a>.

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.
