Adaption of Sql-Queries to work with derby:

The following scripts didn't have to be changed:

- ComplexMethod.sql
- DeadAttribute.sql
- DeadCode.sql
- DeadMethod.sql
- GeneralParameter.sql
- GodMethod.sql
- IgnoredAbstraction.sql
- ImproperNameLength.sql
- ImproperNameLengthCPP.sql
- InconsistentOperations.sql
- InterfaceBypass.sql


- ImportChaos.sql (not converted) can not be used with derby, since "group by" and other operations are not appicable to column data type "long varchar". 

- GenerationConflict.sql used a huge cartesian product for calculation. We converted it to a more performant "join" representation.

- ImproperNameLength / ImproperNameLengthCPP: (not converted)
	- "null" not proper type
	- "substring" function not known 
	- "from" keyword not known

- KnowsOfDerived.sql:
		- boolean-value for isStatic is not possible in derby => since isStatic is not used anyhow we remove the column from the query.
		- huge cartesian product needs a lot of time to process => refactor it to "join" structure
		==> TODO: test with example!
		
- LateAbstraction: refactored cartesian product => proper join-structure
			(runtime of query reduced from 130 s to 18 s (in derby))
