All Implemented Interfaces:

Serializable

public abstract class ViewDefinition
extends TableDefinition

Google BigQuery view table definition. BigQuery's views are logical views, not materialized views, which means that the query that defines the view is re-executed every time the view is queried.

useLegacySql

@Nullable
public Boolean useLegacySql()

Returns whether to use BigQuery's legacy SQL dialect for this query. By default this property is set to false. If set to false, the query will use BigQuery's Standard SQL. If set to null or true, legacy SQL dialect is used. This property is experimental and might be subject to change.

toBuilder

public abstract ViewDefinition.Builder toBuilder()

Returns a builder for the ViewInfo object.

Specified by:

toBuilder in class TableDefinition

newBuilder

public static ViewDefinition.Builder newBuilder(String query)

Returns a builder for a BigQuery view definition.

Parameters:

query - the query used to generate the view

newBuilder
