Oracle connector returns blank columns

[Sonja_Bauernfeind]

When loading a table from Oracle in Qlik Sense June 2018, many columns show empty although they do have values in the database. 

Environment:
Qlik Sense June 2018 (ODBC Connector Package 5.2)

Fixed in:

Qlik Sense February 2019 Patch 1 (Release notes)
Qlik Sense April 2019 (Release notes)
and later releases.

See the relevant Release Notes for ID QVXODBC-1615.

The workaround in previous versions:

Add an advanced parameter MEMLIM = 2000000 to the connector dialog. This increases the size of the buffer that the driver uses for data retrieval.
