Bad luck. Because of our main customer (our own company) we had to change
the like-predicate according to SQL92-standard, meaning that only
'%' and '_' as written in the docs 
http://www.sapdb.org/7.4/htmhelp/8c/ccce27c71c11d2a97100a0c9449261/frameset.htm
are handled starting with 7.4.3.17.

In your example cNumber >= '9660' and cNumber < '9666' could be helpful.
in more complex situations (several ranges in the like-pattern) this will not do,
unfortunately.

Yes, we are thinking of regexp in SAP DB, but no decision made and no timeschedule 
available.
