导出模型中表的DDL语句
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
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
project_id |
是 |
String |
项目ID,获取方法请参见项目ID和账号ID。 |
model_id |
是 |
String |
所属关系建模的模型ID,填写String类型替代Long类型。model_id可从接口获取模型中获取。 |
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
tb_names |
否 |
Array of strings |
待导出的表名。 |
with_db |
否 |
Boolean |
导出的DDL包不包括数据库名。 |
请求参数
参数 |
是否必选 |
参数类型 |
描述 |
---|---|---|---|
X-Auth-Token |
是 |
String |
IAM Token,通过调用IAM服务获取用户Token接口获取(响应消息头中X-Subject-Token的值) 使用Token认证时必选。 |
workspace |
是 |
String |
工作空间ID,获取方法请参见实例ID和工作空间ID。 |
X-Project-Id |
否 |
String |
项目ID,获取方法请参见项目ID和账号ID。 多project场景采用AK/SK认证的接口请求,则该字段必选。 |
Content-Type |
否 |
String |
默认值:application/json;charset=UTF-8 可选,有Body体的情况下必选,没有Body体则无需填写和校验。 |

GET https://{endpoint}/v2/{project_id}/design/workspaces/1217123720355803136/export?with_db=true&tb_names=class&tb_names=trl_aSCb01c
响应示例
状态码: 200
Success,返回data数据是DDL文本信息。
{ "data" : { "value" : "CREATE TABLE IF NOT EXISTS ${database}.class (\n class_id BIGINT NOT NULL comment '1111',\n class_name VARCHAR(1024) NOT NULL comment '2222',\n teacher VARCHAR(255) comment '3333'\n,\nPRIMARY KEY(class_id)\n);\nALTER TABLE ${database}.pd_test COMMENT '无';\nCREATE TABLE IF NOT EXISTS ${database}.logic_{}$A_2 (\n id VARCHAR(255) \n);\nALTER TABLE ${database}.logic_{}$A_2 COMMENT 'aaa';" } }
状态码: 400
