Controls whether zero-length VARCHAR data is treated as NULLs for insert, load, and update operations.
DBA permissions are not required to set this option. Can be set temporary for an individual connection or for the PUBLIC group. 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.
