Functions ¶
This section is empty.
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 MySqlFlag ¶
type MySqlFlag int32
Flags sent from the MySQL C API
const ( MySqlFlag_EMPTY MySqlFlag = 0 MySqlFlag_NOT_NULL_FLAG MySqlFlag = 1 MySqlFlag_PRI_KEY_FLAG MySqlFlag = 2 MySqlFlag_UNIQUE_KEY_FLAG MySqlFlag = 4 MySqlFlag_MULTIPLE_KEY_FLAG MySqlFlag = 8 MySqlFlag_BLOB_FLAG MySqlFlag = 16 MySqlFlag_UNSIGNED_FLAG MySqlFlag = 32 MySqlFlag_ZEROFILL_FLAG MySqlFlag = 64 MySqlFlag_BINARY_FLAG MySqlFlag = 128 MySqlFlag_ENUM_FLAG MySqlFlag = 256 MySqlFlag_AUTO_INCREMENT_FLAG MySqlFlag = 512 MySqlFlag_TIMESTAMP_FLAG MySqlFlag = 1024 MySqlFlag_SET_FLAG MySqlFlag = 2048 MySqlFlag_NO_DEFAULT_VALUE_FLAG MySqlFlag = 4096 MySqlFlag_ON_UPDATE_NOW_FLAG MySqlFlag = 8192 MySqlFlag_NUM_FLAG MySqlFlag = 32768 MySqlFlag_PART_KEY_FLAG MySqlFlag = 16384 MySqlFlag_GROUP_FLAG MySqlFlag = 32768 MySqlFlag_UNIQUE_FLAG MySqlFlag = 65536 MySqlFlag_BINCMP_FLAG MySqlFlag = 131072 )
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.
type Type ¶
type Type int32
Type defines the various supported data types in bind vars and query results.
