writeDisposition property

String? writeDisposition
getter/setter pair

Options for what to do if the destination table already exists. Possible string values are:

  • "WRITE_DISPOSITION_UNSPECIFIED" : Write disposition is not specified. Defaults to WRITE_TRUNCATE.
  • "WRITE_TRUNCATE" : If the table already exists, BigQuery will overwrite the table data and use the schema from the load.
  • "WRITE_APPEND" : If the table already exists, BigQuery will append data to the table.

Implementation

core.String? writeDisposition;
