Go 各种数据库连接字符串汇总

各种数据库的连接字符串的连接格式(一般叫做database source name, 简称DSN)是不同的，本文汇总了各个数据库驱动程序的字符串连接方式。

一、关系型数据库 1.1 Mysql

[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...¶mN=valueN]
// user@unix(/path/to/socket)/dbname
// root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
// user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
// user:password@/dbname?sql_mode=TRADITIONAL
// user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
// id:password@tcp(your-amazonaws-uri.com:3306)/dbname
// user@cloudsql(project-id:instance-name)/dbname
// user@cloudsql(project-id:regionname:instance-name)/dbname
