Unable to read Oracle data - ORA-22835



I am having an issue to get data from ORACLE and it seems the problem is related when i want to read specific columns.


I tried to limit the length of the column by using Select SUBSTR (Column_Name, 1,4000) From Table_name  but i am still getting the same error.

Any ideas/suggestions on how to solve this is welcomed.

If the data in the column is an Oracle Large OBject (LOB), you might need to use DBMS_LOB to access the data ( to convert CLOB to CHAR or BLOB to RAW.  I've googled several articles (search:  Oracle ora22835).  I believe that this challenge is with Oracle rather than with use of Alteryx.


I did get to read some interesting posts in their community.  One that caught my eye was:


How do you expect anyone to be able to help you if you don't post any information about what you are doing?


Wow!  How helpful was that person?
