null GoDoc Coverage

null is a library with reasonable options for dealing with nullable SQL and JSON values.

Types in null will only be considered null on null input, and will JSON encode to null.

All types implement sql.Scanner and driver.Valuer, so you can use this library in place of sql.NullXXX. All types also implement: encoding.TextMarshaler, encoding.TextUnmarshaler, json.Marshaler, json.Unmarshaler and sql.Scanner.

Installation

Null used to be versioned with gopkg.in, so once you upgrade to v8 and beyond please stop using gopkg.in and ensure you're using vgo, dep or vendoring to version null.

go get -u "github.com/admpub/null"

Usage

import "github.com/admpub/null"

Type Description Notes
null.JSON Nullable []byte Will marshal to JSON null if Invalid. []byte{} input will not produce an Invalid JSON, but []byte(nil) will. This should be used for storing raw JSON in the database. Also has null.JSON.Marshal and null.JSON.Unmarshal helpers to marshal and unmarshal foreign objects.
null.Bytes Nullable []byte []byte{} input will not produce an Invalid Bytes, but []byte(nil) will. This should be used for storing binary data (bytes in PSQL for example) in the database.
null.String Nullable string
null.Byte Nullable byte
null.Bool Nullable bool
null.Time Nullable `time.Time Marshals to JSON null if SQL source data is null. Uses time.Time's marshaler.
null.Float32 Nullable float32
null.Float64 Nullable float64
null.Int Nullable int
null.Int8 Nullable int8
null.Int16 Nullable int16
null.Int32 Nullable int32
null.Int64 Nullable int64
null.Uint Nullable uint
null.Uint8 Nullable uint8
null.Uint16 Nullable uint16
null.Uint32 Nullable uint32
null.Uint64 Nullable uint64

Bugs

json's ",omitempty" struct tag does not work correctly right now. It will never omit a null or empty String. This might be fixed eventually.
