bug：SQLUpdateStatement缺少对with语句的访问

[1123183721]

acceptChild方法访问子节点时漏了with节点

protected void acceptChild(SQLASTVisitor visitor)
{
if (with != null) {
with.accept(visitor);
}

    if (tableSource != null) {
        tableSource.accept(visitor);
    }

    if (from != null) {
        from.accept(visitor);
    }

    for (int i = 0; i < items.size(); i++) {
        SQLUpdateSetItem item = items.get(i);
        if (item != null) {
            item.accept(visitor);
        }
    }

    if (where != null) {
        where.accept(visitor);
    }

    if (orderBy != null) {
        orderBy.accept(visitor);
    }
}
