TEMP_EXTRACT_NULL_AS_EMPTY Option

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.

TEMP_EXTRACT_NULL_AS_EMPTY controls the representation of null values in the output of the data extraction facility for ASCII extractions. When the TEMP_EXTRACT_NULL_AS_EMPTY option is set to ON, a null value is represented as '' (the empty string) for all data types.

The quotes shown above are not present in the extract output file. When the TEMP_EXTRACT_NULL_AS_EMPTY option is set to OFF, the string 'NULL' is used in all cases to represent a NULL value. OFF is the default value.
