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

// 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
