null 
import "gopkg.in/guregu/null.v3"
null is a library with reasonable options for dealing with nullable SQL and JSON values
There are two packages: null and its subpackage zero.
Types in null will only be considered null on null input, and will JSON encode to null. If you need zero and null be considered separate values, use these.
Types in zero are treated like zero values in Go: blank string input will produce a null zero.String, and null Strings will JSON encode to "". Zero values of these types will be considered null to SQL. If you need zero and null treated the same, use these.
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, and json.Unmarshaler.
null package
import "gopkg.in/guregu/null.v3"
null.String
Nullable string.
Marshals to JSON null if SQL source data is null. Zero (blank) input will not produce a null String. Can unmarshal from sql.NullString JSON input or string input.
null.Bool
Nullable bool.
Marshals to JSON null if SQL source data is null. False input will not produce a null Bool. Can unmarshal from sql.NullBool JSON input.
null.Time
Marshals to JSON null if SQL source data is null. Uses time.Time's marshaler. Can unmarshal from pq.NullTime and similar JSON input.
null.Float32
Nullable float32.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Float32. Can unmarshal from null.NullFloat32 JSON input.
null.Float64
Nullable float64.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Float64. Can unmarshal from sql.NullFloat64 JSON input.
null.Int
Nullable int.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int. Can unmarshal from null.NullInt JSON input.
null.Int8
Nullable int8.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int8. Can unmarshal from null.NullInt8 JSON input.
null.Int16
Nullable int16.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int16. Can unmarshal from null.NullInt16 JSON input.
null.Int32
Nullable int32.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int32. Can unmarshal from null.NullInt32 JSON input.
null.Int64
Nullable int64.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int64. Can unmarshal from sql.NullInt64 JSON input.
null.Uint
Nullable uint.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Uint. Can unmarshal from null.NullUint JSON input.
null.Uint8
Nullable uint8.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Uint8. Can unmarshal from null.NullUint8 JSON input.
null.Uint16
Nullable uint16.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Uint16. Can unmarshal from null.NullUint16 JSON input.
null.Uint32
Nullable int32.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Uint32. Can unmarshal from null.NullUint32 JSON input.
null.Int64
Nullable uint64.
Marshals to JSON null if SQL source data is null. Zero input will not produce a null Uint64. Can unmarshal from null.NullUint64 JSON input.
zero package
import "gopkg.in/guregu/null.v3/zero"
zero.String
Nullable string.
Will marshal to a blank string if null. Blank string input produces a null String. Null values and zero values are considered equivalent. Can unmarshal from sql.NullString JSON input.
zero.Int
Nullable int64.
Will marshal to 0 if null. 0 produces a null Int. Null values and zero values are considered equivalent. Can unmarshal from sql.NullInt64 JSON input.
zero.Float
Nullable float64.
Will marshal to 0 if null. 0.0 produces a null Float. Null values and zero values are considered equivalent. Can unmarshal from sql.NullFloat64 JSON input.
zero.Bool
Nullable bool.
Will marshal to false if null. false produces a null Float. Null values and zero values are considered equivalent. Can unmarshal from sql.NullBool JSON input.
zero.Time
Will marshal to the zero time if null. Uses time.Time's marshaler. Can unmarshal from pq.NullTime and similar JSON input.
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.
