getRowRestriction()

public 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 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.

getSamplePercentage()

public double getSamplePercentage()

Optional. Specifies a table sampling percentage. Specifically, the query planner will use TABLESAMPLE SYSTEM (sample_percentage PERCENT). The sampling percentage is applied at the data block granularity. It will randomly choose for each data block whether to read the rows in that data block. For more details, see https://cloud.google.com/bigquery/docs/table-sampling)

optional double sample_percentage = 5 [(.google.api.field_behavior) = OPTIONAL];

Returns
Type	Description
`double`	The samplePercentage.

getSelectedFields(int index)

public String getSelectedFields(int index)

Optional. The names of the fields in the table to be returned. If no field names are specified, then all fields in the table are returned.

Nested fields -- the child elements of a STRUCT field -- can be selected individually using their fully-qualified names, and will be returned as record fields containing only the selected nested fields. If a STRUCT field is specified in the selected fields list, all of the child elements will be returned.

As an example, consider a table with the following schema:

{ "name": "struct_field", "type": "RECORD", "mode": "NULLABLE", "fields": [ { "name": "string_field1", "type": "STRING", . "mode": "NULLABLE" }, { "name": "string_field2", "type": "STRING", "mode": "NULLABLE" } ] }

Specifying "struct_field" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 string_field2 }

Specifying "struct_field.string_field1" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 }

The order of the fields in the read session schema is derived from the table schema and does not correspond to the order in which the fields are specified in this list.

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 ByteString getSelectedFieldsBytes(int index)

Optional. The names of the fields in the table to be returned. If no field names are specified, then all fields in the table are returned.

As an example, consider a table with the following schema:

Specifying "struct_field" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 string_field2 }

Specifying "struct_field.string_field1" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 }

The order of the fields in the read session schema is derived from the table schema and does not correspond to the order in which the fields are specified in this list.

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 int getSelectedFieldsCount()

Optional. The names of the fields in the table to be returned. If no field names are specified, then all fields in the table are returned.

As an example, consider a table with the following schema:

Specifying "struct_field" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 string_field2 }

Specifying "struct_field.string_field1" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 }

The order of the fields in the read session schema is derived from the table schema and does not correspond to the order in which the fields are specified in this list.

repeated string selected_fields = 1;

Returns
Type	Description
`int`	The count of selectedFields.

getSelectedFieldsList()

public ProtocolStringList getSelectedFieldsList()

Optional. The names of the fields in the table to be returned. If no field names are specified, then all fields in the table are returned.

As an example, consider a table with the following schema:

Specifying "struct_field" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 string_field2 }

Specifying "struct_field.string_field1" in the selected fields list will result in a read session schema with the following logical structure:

struct_field { string_field1 }

The order of the fields in the read session schema is derived from the table schema and does not correspond to the order in which the fields are specified in this list.

repeated string selected_fields = 1;

Returns
