Any SQL query that is valid for the database.
For example:
<database driver="oracle.jdbc.driver.OracleDriver" url="jdbc:oracle:thin:@host:1521:salesdb" user="joe" password="password" <query> select * from SalesOrders </query> </database>
Query strings that contain XML meta-characters such as > must be marked as CDATA to prevent the XML parser from interpreting it. For example:
<query>
<![CDATA[
select * from SalesPipeline where confidence > 0.9
]]>
</query>
The field names and types (used by the map elements) are taken from the column names and types of the query result set.
