1.Mysql导出sql脚本

2.修改sql脚本，使powerdesigner识别coment注释

修改前:

ct_no

varchar(30) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT ‘反恐舱单编号；如ams编号’

修改后:

ct_no

varchar(30) NULL DEFAULT NULL COMMENT ‘反恐舱单编号；如ams编号’

修改前:

create_time

datetime(0) NULL DEFAULT NULL COMMENT ‘创建时间’

修改后:

create_time

datetime NULL DEFAULT NULL COMMENT ‘创建时间’

3.power designer导入sql脚本

4.执行脚本替换name显示comment

按CTRL+SHIFT+X

或者

PowerDesigner->Tools->Execute Commands->Edit/Run Scripts

打开脚本执行框，复制以下代码，run执行。
