Databricks Connection: Text fields truncated at 255 characters

melperso21 — Tue, 09 Dec 2025 21:10:32 GMT

Hi Community,

I am facing an issue with my Databricks connection in Qlik Sense.

The Problem: I have a table in Databricks that contains text columns with descriptions longer than 255 characters. When I load this data into Qlik, the text is being truncated (cut off) at exactly 255 characters.

Environment:

Source: Databricks (Hive Metastore)
Connection Type: Qlik Databricks Connector (via Qlik Cloud/SaaS)

What I have tried: I attempted to adjust the settings in the connection dialog, but I couldn't find a direct option that resolves the truncation issue. I suspect this is related to a default driver limitquation for String/Varchar length.

Question: Is there a specific parameter or "Advanced Property" I need to add to the connection string (e.g., in the Name/Value pairs) to allow strings longer than 255 characters?

Thanks in advance for your help!
