問題文
An author builds a dataset on a JDBC connection that returns no listing of schemas and tables. What does the documentation tell the author to do?
選択肢
- Upload a file that lists the schema names, then point the Connections pane at that file to stand in for the listing the source withholds.
- Drag the Manual Query item onto the Join Diagram, then click that table twice to reach the SQL editor where the defining statement is written.
- Switch the dataset over to the transform editor, where a table can be named by hand without any join diagram taking part in it.
- Add the same connection a second time from the Connections pane, which makes Oracle Analytics read the catalog of the source afresh.
