我遇到了一些Go和Gorm包的问题。我试图创建表和插入表使用原始查询。可悲的是,错误说我得到了一个语法错误的SQL代码,但当我试图执行它使用PhpMyAdmin它只是工作正常。
下面是代码最小再现代码:
package main
import (
"gorm.io/driver/mysql"
"gorm.io/gorm"
)
const CREATE_TABLE_SQL = "CREATE TABLE `mytable` (`a` int); INSERT INTO `mytable` (`a`) VALUES (1);"
func main() {
dsn := "sandbox:sandbox@tcp(localhost)/sandbox?charset=utf8mb4&parseTime=True&loc=Local"
db, err := gorm.Open(mysql.Open(dsn))
if err != nil {
panic(err)
}
err2 := db.Exec(CREATE_TABLE_SQL).Error
if err2 != nil {
panic(err2)
}
}
很遗憾,它产生了以下错误:
$ go run .

我目前正在使用Docker运行MySQL容器进行开发。以下是我正在使用的Docker组合:
version: '3.8'
services:
mysql:
image: mysql:8
container_name: mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: sandboxroot
MYSQL_DATABASE: sandbox
MYSQL_USER: sandbox
MYSQL_PASSWORD: sandbox
ports:
- 3306:3306
phpmyadmin:
image: phpmyadmin/phpmyadmin
container_name: phpmyadmin
restart: always
environment:
PMA_HOST: mysql
PMA_PORT: 3306
PMA_USER: sandbox
PMA_PASSWORD: sandbox
ports:
- 8080:80

在连接字符串中,应添加参数
multiStatements=true
因此,您的代码将如下所示:
