orderBy in recursive select query (typo3 / typoscript) - typo3

Question

I have a problem ordering the results from a recursive select-query.
It's just about ordering 2 levels of pages. I want the result to look like this:
Parent 1
Child 1-1
Child 1-2
Parent 2
Child 2-1
Child 2-2
Child 2-3
In my results I want one parent page followed by its children, then the next parent's page followed by its children and so on.
When using orderBy = sorting, I seem to get the results in a kind of "random" order, because it's sorting all the entries by the "sorting" field. It is ignoring if the result is a parent or a child-page of the result.
If I don't use orderBy at all, I get the parent's pages first, then the child's pages (maybe this is just a random result).
How can I sort my results correctly?
(I've been thinking about a workaround, using HMENU or TMENU to display my results in the correct order)
Here's my typoscript:
table=pages
select{
pidInList={leveluid:1}
pidInList.insertData=1
recursive=1
orderBy=sorting
max=200
}

Answer 1

Another option would be to nest the SELECT queries.
If you have the result cached, it's the same anyways ;)
tmp.data = CONTENT
tmp.data {
table = pages
select {
pidInList.data = leveluid:1
orderBy = sorting
max = 200
}
renderObj = CONTENT
renderObj {
table = pages
select {
pidInList.field = uid
orderBy = sorting
}
}
}
