code: public String escapeColumnName(String columnName) {
  		StringBuilder sb = new StringBuilder(columnName.length() + 4);
  		databaseType.appendEscapedEntityName(sb, columnName);
  		return sb.toString();
  	}
docs: Same as {@link #escapeColumnName(StringBuilder, String)} but it will return the escaped string. The StringBuilder
  method is more efficient since this method creates a StringBuilder internally.
