golanggorm框架数据库的连接操作示例-木庄网络博客

本文整理自网络，侵删。

1. 连接数据库

要连接到数据库首先要导入驱动程序。例如

import _ "github.com/go-sql-driver/mysql"

为了方便记住导入路径，GORM包装了一些驱动。

import _ "github.com/jinzhu/gorm/dialects/mysql"
// import _ "github.com/jinzhu/gorm/dialects/postgres"
// import _ "github.com/jinzhu/gorm/dialects/sqlite"
// import _ "github.com/jinzhu/gorm/dialects/mssql"

1.1 MySQL

注：为了处理time.Time，您需要包括parseTime作为参数。（更多支持的参数）

import (
    "github.com/jinzhu/gorm"
    _ "github.com/jinzhu/gorm/dialects/mysql"
)
func main() {
  db, err := gorm.Open("mysql", "user:password@/dbname?charset=utf8&parseTime=True&loc=Local")
  defer db.Close()
}

1.2 PostgreSQL

import (
    "github.com/jinzhu/gorm"
    _ "github.com/jinzhu/gorm/dialects/postgres"
)
func main() {
  db, err := gorm.Open("postgres", "host=myhost user=gorm dbname=gorm sslmode=disable password=mypassword")
  defer db.Close()
}

1.3 Sqlite3

import (
    "github.com/jinzhu/gorm"
    _ "github.com/jinzhu/gorm/dialects/sqlite"
)
func main() {
  db, err := gorm.Open("sqlite3", "/tmp/gorm.db")
  defer db.Close()
}
