I'm not too sure about the exact SQLBase solution, but I could offer a QlikView solution that seems to be a lot more elegant. You can simply format the QlikView number to always carry two digits. Your script would look like this:
NUM(Period, '00') as Period
Periode as Period

Thank you for helping me out, I appreciate that.
The thing is that I need to load (sql) data smaller than e.g. year 2016 period 10.
So if I use (e.g.) 'WHERE period <= 10' in the sql section, I miss periods 11 and 12 for previous years.
That's why I thought to load all years and periods (sql) and than filter the loaded data in the load sector.
But I do not know how to do that.
An other solution is to use a if-then-else in my query, but I cannot find the correct syntax (SQLBase).
I think you should look up the corresponding SQL syntax that will allow you formatting the Year-Month combinations using the SQL syntax. For example, something like this:
Think along the lines of formatting your data in a certain way, NOT along the lines of using CASE or IF statements to determine if the month is less than 10 - it will be way to slow...
