Sdo_util.from_gml311geometry and NLS

Question

Hello,
We use sdo_util for simple conversions between coordinates. The problem is that this function changes NLS settings:

Temporarily, we enclose sdo_util by our function that restores our NLS settings.
Is it a bug or misuse? Strange is that sdo_util.to_gml311geometry doesn't have this feature.
Database version: 11.2.0.2, 11.2.0.3 Standard on different platforms.
I'll appreciate your help.

Answer 1

Czesc nieznany,
I don't see that happening on my default AMERICAN NLS setup for 11.2.0.3. It could be something specific to your Polish setup. I would open a support ticket and post how it gets resolved here.
Cheers,
Paul
