[TYPO3-dev] Use of subqueries

[Rik Willems]

Hi all,

For an extension I planning I wonder about the following. MySQL offers 
the opportunity to use subqueries (and subsubqueries etc). Can any one 
say anything about the use of subqueries in TYPO3 and how they influence 
performance?

An alternative would be to first select through php what you want and 
than afterward write a query without subqueries.

Looking forward to any ideas.

Greets, Rik
