功能介绍

1.支持多种数据库的建表 sql转xorm, 其中包含(pg、oracle、mysql)等数据库; 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(normal, postgresql, oracle), 默认: normal.
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. 所以 normal 状态下可以同时处理多个建表语句; postgresql 和 oracle 由于需要解析注释, 只支持单个建表语句.

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)
);

处理后

package model

import (
    "time"
)

type User struct {
    Id int32 `xorm:"pk autoincr not null int 'id'"`
    Name string `xorm:"not null comment('姓名') varchar(10) 'name'"`
    Gender int8 `xorm:"not null default 0 comment('性别 0-未知 1-男 2-女') tinyint 'gender'"`
    Age int32 `xorm:"not null comment('年龄') int 'age'"`
    CreatedDate time.Time `xorm:"default 'CURRENT_TIMESTAMP' datetime 'created_date'"`
    UpdatedDate time.Time `xorm:"default 'CURRENT_TIMESTAMP' datetime 'updated_date'"`
}

func (u *User) TableName() string {
    return "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';

oracle 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,
