1.1. 数据集说明

1.1.1. 数据集定义

数据集是结构化的数据的集合,对外展示的形式是一张数据表。根据数据集数据的来源,数据集可以分成数据连接SQL查询多表联合数据聚合数据合并等种类。其中,数据连接 类型的数据集的数据来自某个数据源中的某张数据表;SQL查询类型的数据集的数据来自某个数据源中的SQL语句查询生成的结果;多表联合类型的数据集的数据来自已经存在的两个或两个以上的数据集通过字段连接(join)生成的结果;数据聚合 类型的数据集的数据来自已经存在的一个数据集通过字段分组聚合生成的结果;数据合并类型的数据集的数据来自已经存在的两个或两个以上的数据集通过字段对齐后的行合并(union)生成的结果;

POST /api/v1/apps/${appId}/datasets/${datasetId}/replace

需要认证:是

请求参数

数据集的共同结构见数据集结构说明。用文件数据集去替换,参照新建文件数据集的 request body 参数。用数据连接数据集去替换,参照新建数据连接数据集的 request body 参数。用 SQL 查询数据集去替换,参照 SQL 查询数据集的 request body 参数。

当原数据集中的字段被引用后,字段名就不能改变了。如果新的替换表中字段名和原字段名不一致,那需要把新的字段名存到 options.schema[].dbfieldName 里面。

获取数据集中哪些字段被引用了,参照获取数据集所有字段,注意把 url 参数中的 inUseOnly 设置为 true。
