// .NAME vtkSQLTableReader - executes an sql query and retrieves results into a table
//
// .SECTION Description
// vtkSQLTableReader 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 vtkSQLQuery instance.
// Set that query on this filter to extract the query as a table.
//
// .SECTION Thanks
// Thanks to Andrew Wilson from Sandia National Laboratories for his work
// on the database classes.

// vtkSQLDatabase vtkSQLQuery
