writeDisposition property

String? writeDisposition

Specifies the action that occurs if the destination table or partition already exists.

The following values are supported: * WRITE_TRUNCATE: If the table or partition already exists, BigQuery overwrites the entire table or all the partitions data. * WRITE_APPEND: If the table or partition already exists, BigQuery appends the data to the table or the latest partition. * WRITE_EMPTY: If the table already exists and contains data, a 'duplicate' error is returned in the job result. The default value is WRITE_EMPTY.
