ORA-22835 - Error while selecting VARCHAR2(4000) field

3354507Nov 29 2016 — edited Nov 29 2016

Hi,

I am using Oracle SQL Developer 1.5.5.

I am querying a description column (TERM_DESCRIPTION) from Informatica Business Glossary View MRX_BG_TERM and i came across ORA-22835. Here is the screenshot

This column has datatype as VARCHAR2(4000). But it appears to be oracle is considering this as CLOB and suggested the action items.

  • Still I went ahead and tried actions it listed (using Substr, dbms_lob.substr ) but none of them worked
  • Tried looking for maximum length, it has thrown the same error ORA-22835
  • I also tried casting field (TERM_DESCRIPTION) as LONG CHAR(5000), this time it has thrown a different error ORA-00600

Can anyone please help me with the way to read the description column.

Thanks,

Shravan
