serializeStrBefore

protected String serializeStrBefore(com.google.common.collect.ImmutableList<? extends it.unibz.inf.ontop.model.term.ImmutableTerm> terms,
                                    Function<it.unibz.inf.ontop.model.term.ImmutableTerm,String> termConverter,
                                    it.unibz.inf.ontop.model.term.TermFactory termFactory)

The documentation of Denodo does not correspond to the implementation. In particular: SUBSTR( 1, 2) returns the first character of , whereas: SUBSTR( 0, 2) returns the two first character of . Instead, the documentation says that the third parameter ("2" here) should be the length of the returned value. It also says that indices start at 1 for SUBSTR and for POSITION. So: SUBSTR( 1, POSITION( IN )) should be the correct translation. But it returns one more (trailing) character than it should. And if instead we use: SUBSTR( 1, POSITION( IN ) - 1) then Denodo throws the exception: 'ERROR: negative substring length not allowed'

There is also another function: SUBSTRING (, , ) whose indices start at 0, and whose third parameter is the end index of the returned substring (excluded). So according to the documentation, the following should do the trick: SUBSTRING(, 0, POSITION( IN ) - 1) But again, Denodo throws the exception: 'ERROR: negative substring length not allowed'

Instead, we get the desired output with: SUBSTR( 0, POSITION( IN )) which does not make much sense.
