After setting up the data mining repository in 12c, I tried the tutorial in https://www.oracle.com/webfolder/technetwork/tutorials/obe/db/12c/r1/dm/dm_41/ODM12c-41_SQLQry.html#section2s3. However, I can't find the SQL Query Node in the Data folder. Has anyone encountered the same and found an answer (I can't after extensive web search)?
