nullMarker property

String? nullMarker
getter/setter pair

Specifies a string that represents a null value in a CSV file.

For example, if you specify "\N", BigQuery interprets "\N" as a null value when querying a CSV file. The default value is the empty string. If you set this property to a custom value, BigQuery throws an error if an empty string is present for all data types except for STRING and BYTE. For STRING and BYTE columns, BigQuery interprets the empty string as an empty value.

Optional.

Implementation
