[TYPO3] How to get the pageid of the next page in the pagetree

[Janno Schouwenburg]

Does someone know a way to get the pageid of the next page in the tree? Best 
would be in typoscript but also a sql statement would help me. I am looking 
for the next page in the tree nomather what level it's in.

Thanks,
