README

What is it?

The sqltype package is a set of types that embraces the sql.Scanner interface from database/sql to other types, e.g. time.Time with sqltype.NullTime and time.Duration with sqltype.NullDuration.

Prior art

Parts of this are taken from the lib/pq library, e.g. the sqltype.NullTime has been take from here.

Types

type NullDuration

type NullDuration struct {
	Duration time.Duration
	Valid    bool // Valid is true if Duration is not NULL
}

NullDuration represents a time.Duration that may be null. NullDuration implements the sql.Scanner interface so it can be used as a scan destination, similar to sql.NullString.

func (*NullDuration) Scan

func (nd *NullDuration) Scan(value interface{}) error

Scan implements the Scanner interface.

func (NullDuration) Value

func (nd NullDuration) Value() (driver.Value, error)

Value implements the driver Valuer interface.

type NullTime

type NullTime struct {
	Time  time.Time
	Valid bool // Valid is true if Time is not NULL
}

NullTime represents a time.Time that may be null. NullTime implements the sql.Scanner interface so it can be used as a scan destination, similar to sql.NullString.

func (*NullTime) Scan

func (nt *NullTime) Scan(value interface{}) error

Scan implements the Scanner interface.

func (NullTime) Value

func (nt NullTime) Value() (driver.Value, error)

Value implements the driver Valuer interface.
