Cloud Spanner V1 Client - Class TypeCode (1.57.0)

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; null s are always encoded as a JSON null .

Protobuf type google.spanner.v1.TypeCode

  Value: 0 
 

Not specified.

Generated from protobuf enum TYPE_CODE_UNSPECIFIED = 0;

  Value: 1 
 

Encoded as JSON true or false .

Generated from protobuf enum BOOL = 1;

  Value: 2 
 

Encoded as string , in decimal format.

Generated from protobuf enum INT64 = 2;

  Value: 3 
 

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

Generated from protobuf enum FLOAT64 = 3;

  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;

  Value: 5 
 

Encoded as string in RFC 3339 date format.

Generated from protobuf enum DATE = 5;

  Value: 6 
 

Encoded as string .

Generated from protobuf enum STRING = 6;

  Value: 7 
 

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

Generated from protobuf enum BYTES = 7;

  Value: 8 
 

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

Generated from protobuf enum ARRAY = 8;

  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;

  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;

  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;
