ArrayQueryParameter(name, array_type, values)

Named / positional query parameters for array values.

Parameters
Name	Description
name	Optional[str] Parameter name, used via @foo syntax. If None, the parameter can only be addressed via position (?).
array_type	Union[str, ScalarQueryParameterType, StructQueryParameterType] The type of array elements. If given as a string, it must be one of 'STRING', 'INT64', 'FLOAT64', 'NUMERIC', 'BIGNUMERIC', 'BOOL', 'TIMESTAMP', 'DATE', or 'STRUCT'/'RECORD'. If the type is 'STRUCT'/'RECORD' and values is empty, the exact item type cannot be deduced, thus a StructQueryParameterType instance needs to be passed in.
values	List[appropriate type] The parameter array values.
