Problem Note 62591: SAS® assigns expanded length to Netezza NVARCHAR and NCHAR data types when using SAS/ACCESS® Interface to Netezza
NVARCHAR and NCHAR formatted columns are mapped to a CHAR format that is up to four times the database length under the following conditions:
- You connect to a double-byte character set (DBCS) encoded Netezza database such as UTF-8.
- You use SAS session encoding such as Latin1 or other single-byte character set (SBCS) encoding.
Here are the workarounds:
- Set the data to the VARCHAR or CHAR data type in the database before you import.
- Set the desired SAS format with the DBSASTYPE data set option upon import. (See DBSASTYPE= Data Set Option for more information.)
