code: public QueryBuilder<T, ID> leftJoinOr(QueryBuilder<?, ?> joinedQueryBuilder) throws SQLException {
  		addJoinInfo(JoinType.LEFT, null, null, joinedQueryBuilder, JoinWhereOperation.OR);
  		return this;
  	}
docs: Like {@link #leftJoin(QueryBuilder)} but this combines the WHERE statements of two query builders with a SQL
  "OR".
