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 for integer number types that fit in 64 bits (signed or unsigned are all converted to signed)
float64 for floating point values that fit in a float
[]byte for everything else

Types ¶

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.

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.
