marklogic - 删除多个集合失败。

Question

我正在使用以下代码删除 Test1 和 Test2 集合，但我收到 FailedRequestException。请指导我解决此问题。

仅当有多个集合时我才会遇到此问题。

QueryManager queryManager = client.newQueryManager();
DeleteQueryDefinition queryDefinition = queryManager.newDeleteDefinition();
String[] collections = {"Test1", "Test2"};
queryDefinition.setCollections(collections);
queryManager.delete(queryDefinition);

堆栈跟踪

Answer 1

DeleteQueryDefinition 应该只接受一个集合。

换句话来说，DeleteQueryDefinition 接受多个集合是 Java API 中的一个设计错误。

要删除多个集合，您可以多次调用queryManager.delete()。

希望有帮助，
