`` `def` executeStatement(relationStatement : Relation) : Relation

  Executes a statement that returns a relation on this database.

Parameters
  `relationStatement -` The statement to execute.
Returns
  The relation returned by the database for this statement.

`` `def` executeStatement(relationStatement : Relation, debug : Boolean) : Relation

  Executes a statement that returns a relation on this database.

Parameters
  `relationStatement -` The statement to execute.
  `debug -` Whether debugging information should be printed on the console.
Returns
  The relation returned by the database for this statement.
