A Swiss Army Knife helps you generate sql from gorm model struct.
go get github.com/liudanking/gorm2sql
user_email.go:
type UserBase struct {
UserId string `sql:"index:idx_ub"`
Ip string `sql:"unique_index:uniq_ip"`
}
type UserEmail struct {
Id int64 `gorm:"primary_key"`
UserBase
Email string
Sex bool
Age int
Score float64
UpdateTime time.Time `sql:"default:CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP"`
CreateTime time.Time `sql:"default:CURRENT_TIMESTAMP"`
}gorm2sql sql -f user_email.go -s UserEmail -o db.sql
Result:
CREATE TABLE `user_email`
(
`id` bigint AUTO_INCREMENT NOT NULL ,
`user_id` varchar(128) NOT NULL ,
`ip` varchar(128) NOT NULL ,
`email` varchar(128) NOT NULL ,
`sex` boolean NOT NULL ,
`age` int NOT NULL ,
`score` double NOT NULL ,
`update_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`create_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
INDEX idx_ub (`user_id`),
UNIQUE INDEX uniq_ip (`ip`),
PRIMARY KEY (`id`)
) engine=innodb DEFAULT charset=utf8mb4;gorm2sql loads go source file to golang AST, then generate sql according to tag of gorm struct field.
