Reference documentation and code samples for the Cloud Spanner V1 Client class Part.
An ssformat key is composed of a sequence of tag numbers and key column
values. Part
represents a single tag or key column value.
Generated from protobuf message google.spanner.v1.KeyRecipe.Part
Namespace
Google \ Cloud \ Spanner \ V1 \ KeyRecipeMethods
__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ tag
int
If non-zero, tag
is the only field present in this Part
. The part is encoded by appending tag
to the ssformat key.
↳ order
int
Whether the key column is sorted ascending or descending. Only present if tag
is zero.
↳ null_order
int
How NULLs are represented in the encoded key part. Only present if tag
is zero.
↳ type
↳ identifier
string
identifier
is the name of the column or query parameter.
↳ value
Google\Protobuf\Value
The constant value of the key part. It is present when query uses a constant as a part of the key.
↳ random
bool
If true, the client is responsible to fill in the value randomly. It's relevant only for the INT64 type.
↳ struct_identifiers
array
It is a repeated field to support fetching key columns from nested structs, such as STRUCT
query parameters.
