<a name="information_schema"></a><h3>Information Schema</h3>
<p>
The system tables in the schema 'INFORMATION_SCHEMA' contain the meta data
of all tables in the database as well as the current settings.
</p>
<table><tr><th>Table</th><th>Columns</th></tr>
<c:forEach var="item" items="informationSchema">
<tr><td>${item.topic}</td><td>${item.syntax}</td></tr>

<br />
<a name="range_table"></a><h3>Range table</h3>
<p>
The range table is a dynamic system table that contains all values from a start to an end value.
The table contains one column called X. Both the start and end values are included in the result. 
The table is used as follows:
</p>
<pre>
SELECT X FROM SYSTEM_RANGE(1, 10);
</pre>
