Types

type NullDuration

type NullDuration struct {
	Data time.Duration

	Valid bool // Valid is true if Data is not NULL
}

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

func (*NullDuration) Scan

func (nj *NullDuration) Scan(src interface{}) error

Scan implements the sql.Scanner interface.

func (NullDuration) Value

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

Value implements the driver.Valuer interface.

type NullJson

type NullJson struct {
	Data interface{} // must be set with a pointer to zero value of expect type

	Valid bool // Valid is true if Data is not NULL
}

NullJson represents an interface that may be null. NullJson implements the Scanner interface so it can be used as a scan destination, similar to sql.NullString. Deprecate, use go-nulljson instead. For more information, see: https://godoc.org/github.com/searKing/golang/tools/cmd/go-nulljson

func (*NullJson) Scan

func (nj *NullJson) Scan(src interface{}) error

Scan implements the sql.Scanner interface.

func (NullJson) Value

func (nj NullJson) Value() (driver.Value, error)

Value implements the driver.Valuer interface.
