Apache Derby 10.5.3 / SQL Error / SQLState: 42Y03

Question

Apache Derby 10.5.3
This one is working fine:
SELECT schemaname || '.' || tablename as TableName,
SYSCS_UTIL.SYSCS_CHECK_TABLE(schemaname, tablename) AS OK
FROM sys.sysschemas s, sys.systables t
WHERE s.schemaid = t.schemaid
and t.tabletype = 'T';
This one fails!
SELECT schemaname || '.' || tablename as TableName,
SYSCS_UTIL.SYSCS_EXPORT_TABLE('APP', tablename, 'D:\\' || tablename, ';', NULL, NULL) AS OK
FROM sys.sysschemas s, sys.systables t
WHERE s.schemaid = t.schemaid
and t.tabletype = 'T';
Error: 'SYSCS_UTIL.SYSCS_EXPORT_TABLE' wurde nicht als Funktion oder Prozedur erkannt.
SQLState: 42Y03
ErrorCode: 30000
Is there any error in this SQL Statement or is there somthing I missed?

You have an impossible situation. All the data that you have means that you have two contradictory positions. The two opposing positions cannot both be true.
Thus it means that one of your assumptions is wrong. Determine which assumption and it will make it obvious what the problem is.
(And in case anyone else is interested the "stupid" questions above were all common assumptions that one can make which can lead to incorrect conclusions.)
