功能介绍

1.支持多种数据库的建表 sql转ent, 其中包含(pg、mysql)数据库; 建表语句, 建表语句, 建表语句(重要的说3遍)
2.在转换 sql 的时候, 需要确认下是否需要切换处理类型, 暂时支持3种处理方式(mysql, postgresql), 默认: mysql.
3.支持自定义过滤不需要的字段, 多个字段通过 , 隔开 说明: 不能在 sql 中包含注释内容(即: -- xxx 或 # xxx); 由于此工具是通过 ; 来分割语句处理.

示例

mysql 建表语句

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 '性别 0-未知 1-男 2-女',
    age int NOT NULL COMMENT '年龄',
    created_date datetime DEFAULT CURRENT_TIMESTAMP,
    updated_date datetime DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    PRIMARY KEY (id)
);

func (u *User) Edges() []ent.Edge {
    return nil
}

func (u *User) Annotations() []schema.Annotation {
    return []schema.Annotation{entsql.Annotation{Table: "user"}}
}

pgsql 建表语句

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 timestamp without time zone DEFAULT now(),
  updated_date timestamp without time zone DEFAULT now(),
  CONSTRAINT user_pkey PRIMARY KEY (id)
);
COMMENT ON TABLE user IS '用户表';
COMMENT ON COLUMN user.id IS '主键';
COMMENT ON COLUMN user.name IS '姓名';
COMMENT ON COLUMN user.gender IS '性别 0-未知 1-男 2-女';
COMMENT ON COLUMN user.age IS '年龄';
COMMENT ON COLUMN user.created_date IS '创建时间';
COMMENT ON COLUMN user.updated_date IS '更新时间';
