Type Description
Long

getSchemaUpdateOptions()

public abstract List<JobInfo.SchemaUpdateOption> getSchemaUpdateOptions()

[Experimental] Returns options allowing the schema of the destination table to be updated as a side effect of the query job. Schema update options are supported in two cases: when writeDisposition is WRITE_APPEND; when writeDisposition is WRITE_TRUNCATE and the destination table is a partition of a table, specified by partition decorators. For normal tables, WRITE_TRUNCATE will always overwrite the schema.

Returns
Type Description
List<SchemaUpdateOption>

getTableDefinitions()

public abstract Map<String,ExternalTableDefinition> getTableDefinitions()

Returns the external tables definitions. If querying external data sources outside of BigQuery, this value describes the data format, location and other properties of the data sources. By defining these properties, the data sources can be queried as if they were standard BigQuery tables.

Returns
Type Description
