I don’t run across this very often but I’m going to start referencing errors here for my reference, this information is strait from MOS support doc (1047894.1)

Applies to:
Oracle Taleo Platform Cloud Service – Connect – Version 12A and later
Information in this document applies to any platform.

Purpose
ORA-00932: inconsistent datatypes: expected – got CLOB
ORA-00932: inconsistent datatypes: expected – got BLOB

These errors are raised when an export file has the Prevent Duplicates flag checked and include a projection for a field that is stored as a BLOB or CLOB in the database.

The BLOB and CLOB type fields include:

JobInformation,DescriptionExternalHTML
JobInformation,DescriptionInternalHTML
JobInformation,ExternalQualificationHTML
JobInformation,InternalQualificationHTML
CandidateAttachedFile,Content

Troubleshooting Steps
To resolve the issue, use one of the following solutions:

Uncheck the Prevent Duplicates flag in the selection query (sq.xml) file.
Remove the problematic projections from the export file.
Apply the To char function to the projection.
