Types

type BindVariable

type BindVariable struct {
	Type  Type   `protobuf:"varint,1,opt,name=type,enum=query.Type" json:"type,omitempty"`
	Value []byte `protobuf:"bytes,2,opt,name=value,proto3" json:"value,omitempty"`
	// values are set if type is TUPLE.
	Values []*Value `protobuf:"bytes,3,rep,name=values" json:"values,omitempty"`
}

BindVariable represents a single bind variable in a Query.

type EventToken

type EventToken struct {
	// timestamp is the MySQL timestamp of the statements. Seconds since Epoch.
	Timestamp int64 `protobuf:"varint,1,opt,name=timestamp" json:"timestamp,omitempty"`
	// The shard name that applied the statements. Note this is not set when
	// streaming from a vttablet. It is only used on the client -> vtgate link.
	Shard string `protobuf:"bytes,2,opt,name=shard" json:"shard,omitempty"`
	// The position on the replication stream after this statement was applied.
	// It is not the transaction ID / GTID, but the position / GTIDSet.
	Position string `protobuf:"bytes,3,opt,name=position" json:"position,omitempty"`
}

EventToken is a structure that describes a point in time in a replication stream on one shard. The most recent known replication position can be retrieved from vttablet when executing a query. It is also sent with the replication streams from the binlog service.

type Field

type Field struct {
	// name of the field as returned by mysql C API
	Name string `protobuf:"bytes,1,opt,name=name" json:"name,omitempty"`
	// vitess-defined type. Conversion function is in sqltypes package.
	Type Type `protobuf:"varint,2,opt,name=type,enum=query.Type" json:"type,omitempty"`
	// Remaining fields from mysql C API.
	// These fields are only populated when ExecuteOptions.included_fields
	// is set to IncludedFields.ALL.
	Table    string `protobuf:"bytes,3,opt,name=table" json:"table,omitempty"`
	OrgTable string `protobuf:"bytes,4,opt,name=org_table,json=orgTable" json:"org_table,omitempty"`
	Database string `protobuf:"bytes,5,opt,name=database" json:"database,omitempty"`
	OrgName  string `protobuf:"bytes,6,opt,name=org_name,json=orgName" json:"org_name,omitempty"`
	// column_length is really a uint32. All 32 bits can be used.
	ColumnLength uint32 `protobuf:"varint,7,opt,name=column_length,json=columnLength" json:"column_length,omitempty"`
	// charset is actually a uint16. Only the lower 16 bits are used.
	Charset uint32 `protobuf:"varint,8,opt,name=charset" json:"charset,omitempty"`
	// decimals is actualy a uint8. Only the lower 8 bits are used.
	Decimals uint32 `protobuf:"varint,9,opt,name=decimals" json:"decimals,omitempty"`
	// flags is actually a uint16. Only the lower 16 bits are used.
	Flags uint32 `protobuf:"varint,10,opt,name=flags" json:"flags,omitempty"`
}

Field describes a single column returned by a query

type ResultExtras

type ResultExtras struct {
	// event_token is populated if the include_event_token flag is set
	// in ExecuteOptions.
	EventToken *EventToken `protobuf:"bytes,1,opt,name=event_token,json=eventToken" json:"event_token,omitempty"`
	// If set, it means the data returned with this result is fresher
	// than the compare_token passed in the ExecuteOptions.
	Fresher bool `protobuf:"varint,2,opt,name=fresher" json:"fresher,omitempty"`
}

ResultExtras contains optional out-of-band information. Usually the extras are requested by adding ExecuteOptions flags.

type Row

type Row struct {
	// lengths contains the length of each value in values.
	// A length of -1 means that the field is NULL. While
	// reading values, you have to accummulate the length
	// to know the offset where the next value begins in values.
	Lengths []int64 `protobuf:"zigzag64,1,rep,packed,name=lengths" json:"lengths,omitempty"`
	// values contains a concatenation of all values in the row.
	Values []byte `protobuf:"bytes,2,opt,name=values,proto3" json:"values,omitempty"`
}

Row is a database row.
