Go implementation of MS SQL Server Uniqueidentifier type.

mssql-uuid

• Go implementation of MS SQL Server uniqueidentifier type.
• Implements the JSON Marshal/Unmarshal and SQL Scan interfaces to ensure that data is read correctly from DB.
• The uniqueidentifier data type is a 16-byte GUID*.
• This data type is used as primary key alternative to identity columns.
• uniqueidentifier is globally unique, whereas identity is unique within a table.
• Can be used alongside ORM such as GORM

Example

package main

import uuid "github.com/tentone/mssql-uuid"

func main() {
	var uid uuid.UUID = uuid.NewV4()
	print(uid.String())
}

UUID Storage

• Microsoft implementation of UUID uses litle endian for the first half the first 8 bytes, and big Endian encoding for the second 8 bytes.
• Because of this other UUID libs fail to correctly parse the data.
