功能介绍

根据模型ID导出指定表的DDL语句。

调用方法

请参见如何调用API

URI

GET /v2/{project_id}/design/workspaces/{model_id}/export

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方法请参见项目ID和账号ID

model_id

String

所属关系建模的模型ID,ID字符串。model_id可从接口获取模型中获取。

表2 Query参数

参数

是否必选

参数类型

描述

tb_names

Array of strings

待导出的表名。
