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

TypeCode is used as part of Type to indicate the type of a Cloud Spanner value.

Each legal value of a type can be encoded to or decoded from a JSON value, using the encodings described below. All Cloud Spanner values can be null, regardless of type; nulls are always encoded as a JSON null.

Constants

TYPE_CODE_UNSPECIFIED

Value: 0

Not specified.

Generated from protobuf enum TYPE_CODE_UNSPECIFIED = 0;

BOOL

Value: 1

Encoded as JSON true or false.

Generated from protobuf enum BOOL = 1;

INT64

Value: 2

Encoded as string, in decimal format.

Generated from protobuf enum INT64 = 2;

FLOAT64

Value: 3

Encoded as number, or the strings "NaN", "Infinity", or "-Infinity".

Generated from protobuf enum FLOAT64 = 3;

TIMESTAMP

Value: 4

Encoded as string in RFC 3339 timestamp format. The time zone must be present, and must be "Z".

If the schema has the column option allow_commit_timestamp=true, the placeholder string "spanner.commit_timestamp()" can be used to instruct the system to insert the commit timestamp associated with the transaction commit.

Generated from protobuf enum TIMESTAMP = 4;

DATE

Value: 5

Encoded as string in RFC 3339 date format.

Generated from protobuf enum DATE = 5;

STRING

Value: 6

Encoded as string.

Generated from protobuf enum STRING = 6;

BYTES

Value: 7

Encoded as a base64-encoded string, as described in RFC 4648, section 4.

Generated from protobuf enum BYTES = 7;

PBARRAY

Value: 8

Encoded as list, where the list elements are represented according to array_element_type.

Generated from protobuf enum ARRAY = 8;

STRUCT

Value: 9

Encoded as list, where list element i is represented according to [struct_type.fields[i]][google.spanner.v1.StructType.fields].

Generated from protobuf enum STRUCT = 9;

NUMERIC

Value: 10

Encoded as string, in decimal format or scientific notation format.

Decimal format:
[+-]Digits[.[Digits]] or
<xref uid="\\Digits">+-</xref>.Digits Scientific notation:
[+-]Digits[.[Digits]][ExponentIndicator[+-]Digits] or
<xref uid="\\Digits">+-</xref>.Digits[ExponentIndicator[+-]Digits]
(ExponentIndicator is "e" or "E")

Generated from protobuf enum NUMERIC = 10;

JSON

Value: 11

Encoded as a JSON-formatted string as described in RFC 7159. The following rules are applied when parsing JSON input:

• Whitespace characters are not preserved.

• If a JSON object has duplicate keys, only the first key is preserved.

• Members of a JSON object are not guaranteed to have their order preserved.
• JSON array elements will have their order preserved.

Generated from protobuf enum JSON = 11;
