2.Enterprise Architect原始DDL模板配置及存在的问题

查看原始DDL模板
在这里插入图片描述

1.DDL Column Definition原始模板（没有default值：可忽略）

6.导入数据库

6.1关于创建时间和修改时间自动填充更新的问题

要实现Java程序在插入数据时自动填充创建时间，在修改数据时自动填充修改时间，需要改一下相关字段的默认值
1、新建表时配置
自动获取创建时间：timestamp not null default CURRENT_TIMESTAMP
自动获取更新时间：timestamp not null default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP

create table test(
  id integer not null auto_increment primary key,
  name varchar(20) not null ,
  create_time timestamp not null default CURRENT_TIMESTAMP COMMENT '创建时间',
  update_time timestamp not null default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP COMMENT '更新时间');

2.修改现有表时配置
2.1用sql语句改

 ALTER TABLE test MODIFY create_time timestamp not null default CURRENT_TIMESTAMP COMMENT '创建时间';
 ALTER TABLE test MODIFY update_time timestamp not null default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP COMMENT '更新时间';

2.2用客户端改
2.1.创建时间默认值设为CURRENT_TIMESTAMP
在这里插入图片描述

2.修改时间默认值设为CURRENT_TIMESTAMP，同时勾选“根据当前时间戳更新”
在这里插入图片描述
