#'
#' @usage TruncateCDMTables(connectionDetails,cdmDatabaseSchema)
#'
#' @param connectionDetails  An R object of type\cr\code{connectionDetails} created using the
#'                                     function \code{createConnectionDetails} in the
#'                                     \code{DatabaseConnector} package.
#' @param cdmDatabaseSchema  The name of the database schema that contains the OMOP CDM
#'                                     instance.  Requires read and write permissions to this database. On SQL
#'                                     Server, this should specifiy both the database and the schema,
