As mentioned on the list, I am currently working on a golang client/driver for avatica using protobufs for serialization.

I've got all datatypes working, except for BINARY and VARBINARY.

For my test table looks like this:
CREATE TABLE test (int INTEGER PRIMARY KEY, bin BINARY(20), varbin VARBINARY) TRANSACTIONAL=false

In go, we have a datatype called a slice of bytes ([]byte) which is essentially an array of bytes (8-bits each).

When I generated the golang protobufs using the .proto files, this is the definition of TypedValue:
type TypedValue struct {
Type Rep `protobuf:"varint,1,opt,name=type,enum=Rep" json:"type,omitempty"` BoolValue bool `protobuf:"varint,2,opt,name=bool_value,json=boolValue" json:"bool_value,omitempty"` StringValue string `protobuf:"bytes,3,opt,name=string_value,json=stringValue" json:"string_value,omitempty"` NumberValue int64 `protobuf:"zigzag64,4,opt,name=number_value,json=numberValue" json:"number_value,omitempty"` BytesValues []byte `protobuf:"bytes,5,opt,name=bytes_values,json=bytesValues,proto3" json:"bytes_values,omitempty"` DoubleValue float64 `protobuf:"fixed64,6,opt,name=double_value,json=doubleValue" json:"double_value,omitempty"` Null bool `protobuf:"varint,7,opt,name=null" json:"null,omitempty"`
}

I am currently creating a TypedValue that looks like this when sending binary data:
{BYTE_STRING false  0 [116 101 115 116] 0 false}

So, the Rep is set to BYTE_STRING and ByteValues is populated with the string "test" in bytes (it's shown here as decimal because I printed it).

The problem is that even though the insert executes properly, if I look at the row using SquirrelSQL, both the BINARY and VARBINARY columns are <null>.

Is BYTE_STRING the correct rep type for sending binary data? Do I also have to encode my bytes in a special format?

Thanks!
