If your data contains NLS characters, you might receive errors in the SAS log that stop processing for a DATA step. If you prefer to continue with processing, you can enable the SAS_POSTGRES_UPDATE_WARNING= environment variable. When you specify SAS_POSTGRES_UPDATE_WARNING=1, then a warning is printed to the SAS log and processing continues.
The warning might resemble the following example:
WARNING: During update: [SAS][ODBC PostgreSQL Wire Protocol driver]No rows were affected by UPDATE/DELETE WHERE CURRENT OF cursor
