NON_ANSI_NULL_VARCHAR
Option
Controls whether zero-length VARCHAR data is treated as NULLs for insert, load, and update operations.
ON, OFF
OFF
Option can be set at the database (PUBLIC) or user level. At the database level, the value becomes the default for any new user, but has no impact on existing users. At the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.
Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.
NON_ANSI_NULL_VARCHAR lets you revert to non-ANSI (Version 12.03.1) behavior for treating zero-length VARCHAR data during load or update operations. When this option is set to OFF, zero-length VARCHAR data is stored as zero-length during load, insert, or update. When this option is set to ON, zero-length VARCHAR data is stored as NULLs on load, insert, or update.
