| <<pk>> | PRIMARY KEY | id : bigint(20) <<pk>> |
| * | NOT NULL | *type : tinyint(4) |

table COMMENT '{TABLE_COMMENT}' | entity "tbl_user" { 用户表 -- } entity "tbl_user" { 用户表 .. } entity "tbl_user" { 用户表 == } entity "tbl_user" { 用户表 __ } |
Usage
Convert PlantUML to DDL
- Open a PlantUML file
- In this file, Right-click or Alt-Insert
- Select
Generate->PlantUML -> DDL.
For example: mall.puml
@startuml
' hide the spot
hide circle
' avoid problems with angled crows feet
skinparam linetype ortho
entity "tbl_user" as user {
用户表
--
#id : bigint(20) <<generated>>
--
*type : tinyint(4) <<default:0>> --用户类型：0-PC用户,1-移动端用户
*name : varchar(50) <<default:'anonymous'>> --用户名
description : varchar(200) <<default:'some string'>> --用户描述
}
entity "tbl_order" as order {
订单表
==
#id : bigint(20) <<generated>>
--
* **order_number** : varchar(20) <<default:'0'>> -- 订单号
*user_id : bigint(20) <<FK>> <<default:0>> -- 用户id
*item_id: bigint(20) <<FK>> <<default:0>> -- 商品id
}
entity "tbl_item" as item {
商品表
..
#id : bigint(20) <<generated>>
--
title : varchar(50) <<default: 'wahaha'>> <<notnull>> -- 商品标题
*price : int(11) <<default: 0>> -- 商品价格
}
user }|..|{ order
item }|..|{ order

In the same directory, will generate a file mall-{yyyyMMddHHmmss}.sql:
CREATE TABLE IF NOT EXISTS `tbl_user` (
`id` BIGINT(20) NOT NULL AUTO_INCREMENT,
`type` TINYINT(4) NOT NULL DEFAULT 0 COMMENT '用户类型：0-PC用户,1-移动端用户',
`name` VARCHAR(50) NOT NULL DEFAULT 'anonymous' COMMENT '用户名',
`description` VARCHAR(200) DEFAULT 'some string' COMMENT '用户描述',
PRIMARY KEY (`id`)
) COMMENT '用户表';
CREATE TABLE IF NOT EXISTS `tbl_order` (
`id` BIGINT(20) NOT NULL AUTO_INCREMENT,
`order_number` VARCHAR(20) NOT NULL DEFAULT '0' COMMENT '订单号',
`user_id` BIGINT(20) NOT NULL DEFAULT 0 COMMENT '用户id',
`item_id` BIGINT(20) NOT NULL DEFAULT 0 COMMENT '商品id',
PRIMARY KEY (`id`)
) COMMENT '订单表';
CREATE TABLE IF NOT EXISTS `tbl_item` (
`id` BIGINT(20) NOT NULL AUTO_INCREMENT,
`title` VARCHAR(50) NOT NULL DEFAULT 'wahaha' COMMENT '商品标题',
`price` INT(11) NOT NULL DEFAULT 0 COMMENT '商品价格',
PRIMARY KEY (`id`)
) COMMENT '商品表';
