Body
Here are a few examples of errors that can occur even with SQL statements that are syntactically correct and which may work in your development environment: <ul> <li><a href="http://dev.mysql.com/doc/refman/5.1/en/constraint-primary-key.html" rel="nofollow noreferrer">Duplicate key violation</a> from an <code>INSERT</code> or <code>UPDATE</code>. That is, a <code>PRIMARY KEY</code> or <code>UNIQUE KEY</code> prevents you from setting a column to the same value in another row. Sleeping is not likely to fix this, you need to change the values you're inserting/updating.</li> <li><a href="http://dev.mysql.com/doc/refman/5.1/en/constraint-invalid-data.html" rel="nofollow noreferrer">Constraint violations</a> such as unsatisfied <a href="http://dev.mysql.com/doc/refman/5.0/en/innodb-foreign-key-constraints.html" rel="nofollow noreferrer">foreign key</a> references or setting a <code>NOT NULL</code> column to NULL. You need to insert/update using values that do not violate the constraints. Deleting a row that has foreign key dependencies results in an error unless you defined cascading behavior in the FK constraint declaration. Also it's an error to insert or update using a value that's out of range for a column's data type.</li> <li><a href="http://dev.mysql.com/doc/refman/5.1/en/privilege-system.html" rel="nofollow noreferrer">SQL privileges</a> can restrict the operations you can perform.</li> <li><code>SELECT</code> may give an error if you generate queries dynamically with your application code, and the query it generates is flawed.</li> <li>A query that worked before may give an error if someone changes the MySQL <a href="http://dev.mysql.com/doc/refman/5.1/en/server-sql-mode.html" rel="nofollow noreferrer"><code>SQL MODE</code></a> to be more strict. For example, some implicit data type conversions or permissive enforcement of the Single-Value Rule in <code>GROUP BY</code> queries may fail.</li> </ul>

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.
