/**
 * @class vtkRowQueryToTable
 * @brief executes an sql query and retrieves results into a table
 *
 *
 * vtkRowQueryToTable creates a vtkTable with the results of an arbitrary SQL
 * query. To use this filter, you first need an instance of a vtkSQLDatabase
 * subclass. You may use the database class to obtain a vtkRowQuery instance.
 * Set that query on this filter to extract the query as a table.
 *
 * @par Thanks:
 * Thanks to Andrew Wilson from Sandia National Laboratories for his work
 * on the database classes.
