Golang (Go) SQL+JSON+Validator Support for Null Database/SQL Types

SQL Null Field Types

• sql.NullString
• sql.NullBool
• sql.NullInt64
• sql.NullFloat64

Adds support to Null* field types for database/sql.

Validator library is:

• Go Playground Validator: gopkg.in/go-playground/validator.v9

Allows simultaneous use of validator validations, null sql values in struct fields for database/sql, and still support JSON Marshal and Unmarshal for those Null* fields.

Usage

Please see integration test files, in particular those for validation.

You need to register custom types for validator. See how it is done in integration tests too.
