Though this is not directly related to the OP's exact question but I just found out that using a Oracle reserved word in your query (in my case the alias IN
) can cause the same error.
Example:
SELECT * FROM TBL_INDEPENTS IN
JOIN TBL_VOTERS VO on IN.VOTERID = VO.VOTERID
Or if its in the query itself as a field name
SELECT ..., ...., IN, ..., .... FROM SOMETABLE
That would also throw that error. I hope this helps someone.
