sqlt: More SQL types for Go

Overview

Note: This module should not be used in new code. The generic type database/sql.Null is available in the standard library since Go 1.22.

The sqlt package provides types that implement Go's database/sql.Scanner and database/sql/driver.Valuer interfaces:

• github.com/soroushj/sqlt.NullRawMessage - Nullable encoding/json.RawMessage
• github.com/soroushj/sqlt.NullUUID - Nullable github.com/google/uuid.UUID (Note: This type should not be used in new code. github.com/google/uuid.NullUUID is available since v1.3.0.)

Overview

Package sqlt provides types that implement the database/sql.Scanner and database/sql/driver.Valuer interfaces.

Note: This module should not be used in new code. The generic type database/sql.Null is available in the standard library since Go 1.22.

Index

• type NullRawMessage
  • func (nm *NullRawMessage) Scan(value interface{}) error
  • func (nm NullRawMessage) Value() (driver.Value, error)
• type NullUUID
  • func (nu *NullUUID) Scan(value interface{}) error
  • func (nu NullUUID) Value() (driver.Value, error)

Types

type NullRawMessage

type NullRawMessage struct {
	RawMessage json.RawMessage
	Valid      bool // Valid is true if RawMessage is not NULL
}

NullRawMessage represents a encoding/json.RawMessage that may be null. NullRawMessage implements the database/sql.Scanner interface so it can be used as a scan destination.

func (*NullRawMessage) Scan

func (nm *NullRawMessage) Scan(value interface{}) error

Scan implements the database/sql.Scanner interface.

func (NullRawMessage) Value

func (nm NullRawMessage) Value() (driver.Value, error)

Value implements the database/sql/driver.Valuer interface.

type NullUUID

type NullUUID struct {
	UUID  uuid.UUID
	Valid bool // Valid is true if UUID is not NULL
}

NullUUID represents a github.com/google/uuid.UUID that may be null. NullUUID implements the database/sql.Scanner interface so it can be used as a scan destination.

Note: This type should not be used in new code. github.com/google/uuid.NullUUID is available since v1.3.0.

func (*NullUUID) Scan

func (nu *NullUUID) Scan(value interface{}) error

Scan implements the database/sql.Scanner interface.

func (NullUUID) Value

func (nu NullUUID) Value() (driver.Value, error)

Value implements the database/sql/driver.Valuer interface.
