GORM CheatSheet

To import the module and init db connection

import (
  "gorm.io/driver/mysql"
  "gorm.io/driver/postgres"
  "gorm.io/gorm"
)

func main() {
  // MYSQL:
  // refer https://github.com/go-sql-driver/mysql#dsn-data-source-name for details
  dsn := "user:pass@tcp(127.0.0.1:3306)/dbname?charset=utf8mb4&parseTime=True&loc=Local"
  db, err := gorm.Open(mysql.Open(dsn), &gorm.Config{})

  // PostgreSQL:
  dsn := "host=localhost user=gorm password=gorm dbname=gorm port=9920 sslmode=disable TimeZone=Asia/Shanghai"
  db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{})

  // SQLite:
  db, err := gorm.Open(sqlite.Open("gorm.db"), &gorm.Config{})

  // SQL Server:
  dsn := "sqlserver://gorm:LoremIpsum86@localhost:9930?database=gorm"
  db, err := gorm.Open(sqlserver.Open(dsn), &gorm.Config{})
}

• To handle time.Time correcxtly, include the parseTime as a parameter
