问题 Im new to oracle multidimensional models... I have followed the "Creating a Multidimensional Model" 15 min Oracle tutorial. Tutorial Link Note: This tutorial use sql developer data modeler. I would like to know how to query the created data cube using SQL Developer (I.E. using regular SQL DML statements).

问题 In Toad one can easily execute current line without highlighting it. Let say, you have a worksheet like this: select * from item -- cursor here select * from product When I click on CTRL+Enter I want only the line where the cursor is to be executed.

Basically, I want to do the same as described here, but for some reason, I can't find the Tools -> Preferences -> Window Types -> SQL Window and check "AutoSelect statement"

问题 I have 2 tables, a Users table and a User_permissions table. A user can have many permissions and each permission can be assigned to many different users, although this relationship has not been configured into the database (not my decision!). Let's say 2 new permissions are created - an admin permission and a superadmin permission. Furthermore, every user in the Users table need to be given this permission by inserting the username and permission name into the User_permissions table.

问题 I am trying to run the below query but looks like I am doing something wrong. (Just modified the sample query for clear understanding) SELECT name,total,rate FROM business b WHERE rate > 100 ORDER BY total DESC UNION SELECT name,total,rate FROM business b WHERE rate <= 100 ORDER BY rate ASC Now I want to union of these two queries and in the resultant output in first row the output should come from first query and then output from second query in the same sorted order however the single
