Thus, using multiple columns implies a hierarchical structure of columns, which is 
 usually used for partitioning tables. This processor can be used to retrieve only those rows that have been added/updated since the last retrieval. Note that some JDBC types such as bit/boolean are not conducive to maintaining maximum value, so columns of these types should not be listed in this property, and will result in error(s) during processing.

+    		QueryRecord provides users a tremendous amount of power by leveraging an extremely well-known
+    		syntax (SQL) to route, filter, transform, and query data as it traverses the system. In order to
+    		provide the Processor with the maximum amount of flexibility, it is configured with a Controller
+    		Service that is responsible for reading and parsing the incoming FlowFiles and a Controller Service
+    		that is responsible for writing the results out. By using this paradigm, users are not forced to
+    		convert their data from one format to another just to query it, and then transform the data back
+    		into the form that they want. Rather, the appropriate Controller Service can easily be configured
+    		and put to use for the appropriate data format. 
+    	</p>
+    	
+    	<p>
+    		Rather than providing a single "SQL SELECT Statement" type of Property, this Processor makes use
+    		of user-defined properties. Each user-defined property that is added to the Processor has a name
+    		that becomes a new Relationship for the Processor and a corresponding SQL query that will be evaluated
+    		against each FlowFile. This allows multiple SQL queries to be run against each FlowFile.
+    	</p>
+    	
+    	<p>
+			The SQL syntax that is supported by this Processor is ANSI SQL and is powered by Apache Calcite. Please
+			note that identifiers are quoted using double-quotes, and column names/labels are case-insensitive.

The result of the SQL query then becomes the content of the output FlowFile. This can be used, for example, for field-specific filtering, transformation, and row-level filtering. Columns can be renamed, simple calculations and aggregations performed, etc. The Processor is configured with a Record Reader Controller Service and a Record Writer service so as to allow flexibility in incoming and outgoing data formats. The Processor must be configured with at least one user-defined property. The
  name of the Property is the Relationship to route data to, and the value of the Property is a SQL SELECT statement that is used to specify how input data should be transformed/filtered. The SQL statement must be valid ANSI SQL and is powered by Apache Calcite. If the transformation fails, the original FlowFile is routed to the 'failure' relationship. Otherwise, the data selected will be routed to the associated relationship. If the Record Writer chooses to inherit the schema from the Record, it is important to note that the schema that is inherited will be from the ResultSet, rather than the input Record. This allows a single instance of the QueryRecord processor to have multiple queries, each of which returns a different set of columns and aggregations. As a result, though, the schema that is derived will have no schema name, so it is important that the configured Record Writer not attempt to write the Schema Name as an attribute if inheriting the Schema from the Record.

 rocessor Usage documentation for more information.</p><p><a href="additionalDetails.html">Additional Details...</a></p><h3>Tags: </h3><p>sql, query, calcite, route, record, transform, select, update, modify, etl, filter, record, csv, json, logs, text, avro, aggregate</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.

+        <h2>Usage Example</h2>
+        <p>
+            This processor routes FlowFiles based on their attributes
+            using the NiFi Expression Language. Users add properties with
+            valid NiFi Expression Language Expressions as the values. Each Expression must
+            return a value of type Boolean (true or false).
+        </p>
+        <p>
+            Example: The goal is to route all files with filenames that start with ABC down a certain path. 
+            Add a property with the following name and value:
+        </p>
+        <ul>
+            <li><strong>property name</strong>: ABC
+            </li>
+            <li><strong>property value</strong>: ${filename:startsWith('ABC')}
+            </li>
+        </ul>
+        <p>
+            In this example, all files with filenames that start with ABC will follow the ABC relationship.
+        </p>
