Getting warning while doing the test connectivity of a class



Test connectivity of frame work class is throwing warning such as either BLOB or CLOB should be there, not both.

Error Messages

Warning: Class <CLASS-NAME> is mapped to table <TABLE-NAME> which contains both BLOB and CLOB column types. The table should only contain either CLOB or BLOB columns, not both.

Steps to Reproduce

Not Applicable

Root Cause

A validation was added into the Test Connection logic to warn a user if their table contains both a BLOB and a CLOB.


This is an expected behavior and the reason for this behavior is, the property that is stored in the CLOB column will also be stored in the pzPvStream column, this combination could lead to a large amount of space to be taken up in the database for each record.
