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
TypeDescription
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.

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
NameDescription
indexint

The index of the element to return.

Returns
TypeDescription
String

The selectedFields at the given index.

getSelectedFieldsBytes(int index)

The index of the value to return.

Returns
TypeDescription
