Functions

func Convert

func Convert(mysqlType int64, val sqltypes.Value) (interface{}, error)

Convert takes a type and a value, and returns the type: - nil for NULL value - int64 if possible, otherwise, uint64 - float64 for floating point values that fit in a float - []byte for everything else

Types

type Charset

type Charset struct {
	Client int // @@session.character_set_client
	Conn   int // @@session.collation_connection
	Server int // @@session.collation_server
}

Charset contains the per-statement character set settings that accompany binlog QUERY_EVENT entries.

func (*Charset) MarshalBson

func (charset *Charset) MarshalBson(buf *bytes2.ChunkedWriter, key string)

MarshalBson bson-encodes Charset.

func (*Charset) UnmarshalBson

func (charset *Charset) UnmarshalBson(buf *bytes.Buffer, kind byte)

UnmarshalBson bson-decodes into Charset.

type Field

type Field struct {
	Name string
	Type int64
}

Field described a column returned by mysql

func (*Field) MarshalBson

func (field *Field) MarshalBson(buf *bytes2.ChunkedWriter, key string)

MarshalBson bson-encodes Field.

func (*Field) UnmarshalBson

func (field *Field) UnmarshalBson(buf *bytes.Buffer, kind byte)

UnmarshalBson bson-decodes into Field.

type QueryResult

type QueryResult struct {
	Fields       []Field
	RowsAffected uint64
	InsertId     uint64
	Rows         [][]sqltypes.Value
}

QueryResult is the structure returned by the mysql library. When transmitted over the wire, the Rows all come back as strings and lose their original sqltypes. use Fields.Type to convert them back if needed, using the following functions.

func (*QueryResult) MarshalBson

func (queryResult *QueryResult) MarshalBson(buf *bytes2.ChunkedWriter, key string)

MarshalBson bson-encodes QueryResult.

func (*QueryResult) UnmarshalBson

func (queryResult *QueryResult) UnmarshalBson(buf *bytes.Buffer, kind byte)

UnmarshalBson bson-decodes into QueryResult.
