【店小二】公告:
sql轉ent
| | |
功能介紹
1.支持多種數據庫的建表 sql轉ent, 其中包含(pg、mysql)數據庫; 建表語句, 建表語句, 建表語句(重要的說3遍)
2.在轉換 sql 的時候, 需要確認下是否需要切換處理類型, 暫時支持3種處理方式(mysql, postgresql), 默認: mysql.
3.支持自定義過濾不需要的字段, 多個字段通過 , 隔開
說明: 不能在 sql 中包含註釋內容(即:-- xxx
或# xxx
); 由於此工具是通過 ; 來分割語句處理.
示例
mysql 建表語句
CREATE TABLE if not exists user (
id int NOT NULL AUTO_INCREMENT,
name varchar(10) NOT NULL COMMENT '姓名',
gender tinyint NOT NULL DEFAULT 0 COMMENT '性別 0-未知 1-男 2-女',
age int NOT NULL COMMENT '年齡',
created_date datetime DEFAULT CURRENT_TIMESP,
updated_date datetime DEFAULT CURRENT_TIMESP ON UPDATE CURRENT_TIMESP,
PRIMARY KEY (id)
);

)
type User struct {
ent.Schema
}
func (u *User) Fields() []ent.Field {
return []ent.Field{
field.String("id").SchemaType(map[string]string{dialect.MySQL: "character"}).Default(sys_guid).Nillable(),
field.String("name").SchemaType(map[string]string{dialect.MySQL: "character"}).Nillable().Comment("姓名"),
field.Int32("gender").SchemaType(map[string]string{dialect.MySQL: "tinyint"}).Nillable().Comment("性別 0-未知 1-男 2-女"),
field.Int32("age").SchemaType(map[string]string{dialect.MySQL: "tinyint"}).Nillable().Comment("年齡"),
field.Time("created_date").SchemaType(map[string]string{dialect.MySQL: "timesp"}).Optional().Default(now()).Nillable(),
field.Time("updated_date").SchemaType(map[string]string{dialect.MySQL: "timesp"}).Optional().Default(now()).Nillable()
}
}
func (u *User) Edges() []ent.Edge {
return nil
}
func (u *User) Annotations() []schema.Annotation {
return []schema.Annotation{entsql.Annotation{Table: "user"}}
}
pgsql 建表語句
CREATE TABLE if not exists user (
id character varying(32) NOT NULL DEFAULT sys_guid(),
name character varying(10) NOT NULL,
gender tinyint NOT NULL,
age tinyint NOT NULL,
created_date timesp without time zone DEFAULT now(),
updated_date timesp without time zone DEFAULT now(),
CONSTRAINT user_pkey PRIMARY KEY (id)
);
COMMENT ON TABLE user IS '用戶表';
COMMENT ON COLUMN user.id IS '主鍵';
COMMENT ON COLUMN user.name IS '姓名';
COMMENT ON COLUMN user.gender IS '性別 0-未知 1-男 2-女';
COMMENT ON COLUMN user.age IS '年齡';
COMMENT ON COLUMN user.created_date IS '創建時間';
COMMENT ON COLUMN user.updated_date IS '更新時間';
