Reference documentation and code samples for the Cloud Spanner V1 Client class Type.

Type indicates the type of a Cloud Spanner value, as might be stored in a table cell or returned from an SQL query.

Generated from protobuf message google.spanner.v1.Type

Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ code	int Required. The TypeCode for this type.
↳ array_element_type	Google\Cloud\Spanner\V1\Type If code == ARRAY, then array_element_type is the type of the array elements.
↳ struct_type	Google\Cloud\Spanner\V1\StructType If code == STRUCT, then struct_type provides type information for the struct's fields.
↳ type_annotation	int The TypeAnnotationCode that disambiguates SQL type that Spanner will use to represent values of this type during query processing. This is necessary for some type codes because a single TypeCode can be mapped to different SQL types depending on the SQL dialect. type_annotation typically is not needed to process the content of a value (it doesn't affect serialization) and clients can ignore it on the read path.

getCode

Required. The TypeCode for this type.

Returns
Type	Description
int

setCode
