[Joseph_Musekura]

The following error or similar could be generated when loading data of type NCLOB or CLOB from an Oracle Data Source.

ERROR [HY000] [Qlik][OracleOCI] (3000) Oracle Caller Interface: ORA-00942:the table or view does not exist

 Only fields of data type NCLOB or CLOB are affected.

Environment

• Qlik Sense Enterprise May 2022 and other earlier versions.

Resolution

Fix Version

August 2022 Patch 1
May 2022 Patch 7
February 2022 Patch 10
November 2021 Patch 15
and any later releases.

Workaround

A workaround could be a downgrade of Qlik ODBC connector package to the previous working version. Alternatively, you can reach out to Qlik Support in order to get a temporary fixed ODBC connector package version 6.191 (a new official patch will be provided soon).

See How to upgrade the Qlik Sense Enterprise on Windows ODBC Connector Packages for instructions on how to swap out the ODBC Connector Package for Qlik Sense Enterprise on Windows.

Has anyone noticed if this issue also is affecting Oracle SQL queries that are using a function, like substr() ---- or a custom stored function?

Hello @Joseph_Musekura 

there still seems to be something not working in the oracle connector in the nov 2022 patch 2. 

all oracle queries that use joins seem to fail (no error messages, they just keep loading). normal/simple queries seem ok. 

could you check? thanks
