I think there should be a warning in the output if you try to enable 'Character literals' while being a non-ora db.
In our case, this has been a big issue in our project and is still listed as a potential issue.
Should I open a new idea to put a warning in the output?
After reviewing this Idea, it is working as expected. With DB2_COMPATIBILITY_VECTOR=ORA, "Character literals" is enabled:
https://www.ibm.com/docs/en/db2/11.5?topic=oracle-implicit-casting-character-graphic-constants
In this mode, the string literals 'OUT' and 'IN' are CHAR(3) and CHAR(2) respectively. The result type for the CASE expression is thus CHAR(3) and therefore the length is always 3.
