Error with correct long Query in [Read Database] Operator - ORA-01722:invalid number
USING ORACLE 12 and RapidMiner 8.0.001 (FREE)
Get a ORA-01722:invalid number Error in [Read Database] Operator. This is a long running (20s) and complex Query with result about just 170 rows. The query runs fine in my SQL Console. Rapid Miner told me this error after running 7 Seconds... What going on?
Smaller Query run well on this place using [Read Database] Operator.
