You can't in the Execute sequence, but technically it's possible in the UI sequence as RuneC already found out - but it's a trick and you shouldn't use it for a couple of reasons: If your setup runs in silent or Basic UI mode the UI sequence is skipped and the SQL install won't be called. On Vista your custom action in the UI sequence may not have the required permissions to install SQL because of UAC. In general the UI sequence shouldn't modify the target system and there's no rollback functionality in the UI sequence. A bootstrapper is the officially recommended method to chain two msi setups.
