Returns
Type	Description
ArrowSerializationOptions	The arrowSerializationOptions.

getRowRestriction()

public abstract String getRowRestriction()

SQL text filtering statement, similar to a WHERE clause in a query. Aggregates are not supported.

Examples: "int_field > 5" "date_field = CAST('2014-9-27' as DATE)" "nullable_field is not NULL" "st_equals(geo_field, st_geofromtext("POINT(2, 2)"))" "numeric_field BETWEEN 1.0 AND 5.0"

Restricted to a maximum length for 1 MB.

string row_restriction = 2;

Returns
Type	Description
String	The rowRestriction.

getRowRestrictionBytes()

public abstract ByteString getRowRestrictionBytes()

SQL text filtering statement, similar to a WHERE clause in a query. Aggregates are not supported.

Examples: "int_field > 5" "date_field = CAST('2014-9-27' as DATE)" "nullable_field is not NULL" "st_equals(geo_field, st_geofromtext("POINT(2, 2)"))" "numeric_field BETWEEN 1.0 AND 5.0"

Restricted to a maximum length for 1 MB.

string row_restriction = 2;

Returns
Type	Description
ByteString	The bytes for rowRestriction.

getSelectedFields(int index)

public abstract String getSelectedFields(int index)

Names of the fields in the table that should be read. If empty, all fields will be read. If the specified field is a nested field, all the sub-fields in the field will be selected. The output field order is unrelated to the order of fields in selected_fields.

repeated string selected_fields = 1;

Parameter
Name	Description
index	int The index of the element to return.

Returns
Type	Description
String	The selectedFields at the given index.

getSelectedFieldsBytes(int index)

public abstract ByteString getSelectedFieldsBytes(int index)

Names of the fields in the table that should be read. If empty, all fields will be read. If the specified field is a nested field, all the sub-fields in the field will be selected. The output field order is unrelated to the order of fields in selected_fields.

repeated string selected_fields = 1;

Parameter
Name	Description
index	int The index of the value to return.

Returns
Type	Description
ByteString	The bytes of the selectedFields at the given index.

getSelectedFieldsCount()

public abstract int getSelectedFieldsCount()

Names of the fields in the table that should be read. If empty, all fields will be read. If the specified field is a nested field, all the sub-fields in the field will be selected. The output field order is unrelated to the order of fields in selected_fields.

repeated string selected_fields = 1;

Returns
Type	Description
int	The count of selectedFields.

getSelectedFieldsList()

public abstract List<String> getSelectedFieldsList()

Names of the fields in the table that should be read. If empty, all fields will be read. If the specified field is a nested field, all the sub-fields in the field will be selected. The output field order is unrelated to the order of fields in selected_fields.

repeated string selected_fields = 1;

Returns
Type	Description
List<String>	A list containing the selectedFields.

hasArrowSerializationOptions()

public abstract boolean hasArrowSerializationOptions()

Optional. Options specific to the Apache Arrow output format.

.google.cloud.bigquery.storage.v1beta2.ArrowSerializationOptions arrow_serialization_options = 3 [(.google.api.field_behavior) = OPTIONAL];

Returns
Type	Description
boolean	Whether the arrowSerializationOptions field is set.
