# gorm2sql: auto generate sql from gorm model struct

A Swiss Army Knife helps you generate sql from [gorm](https://github.com/jinzhu/gorm) model struct.

## Installation

```

go get github.com/liudanking/gorm2sql

```

## Usage

`user_email.go`:

```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:

```sql

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;

```

## How it works

`gorm2sql` loads go source file to golang AST, then generate sql according to `tag` of gorm struct field.
