 * annotated with @Column(unique = true).
 */
private static void initializeUniqueConstraints(Table table) {
  Iterator<Column> colIterator = table.getColumnIterator();
  while (colIterator.hasNext()) {
    Column col = colIterator.next();
    if (col.isUnique()) {
      String name = Constraint.generateName("UK_", table, col);
      UniqueKey uk = table.getOrCreateUniqueKey(name);
      uk.addColumn(col);
    }
