* 3) We have to keep the entry with the highest autoinc-id, because mysql calculates the
* autoinc-id as "new value = max(row) +1" and does not store this in a separate table.
* This means, if we delete to entry with the highest autoinc-value then this value is

* for example 4 Weeks). This is confusing for our system.
* ATTENTION 2) and 3) is in some case NOT the same! so we have to check both!
