Using SQL SERVER and Cloud Hosted Databases with OBIEE 11g
If your organisation is committed to using Oracle Business Intelligence Enterprise Edition (OBIEE) 10g/11g /12c as their BI solution, you aren't thereby committed to using Oracle throughout your organisation. You can use a range of data sources including SQL Server, and save a great deal of money by doing so. Sadly, Oracle will only support the use of the venerable SQL Server 2008 R2. Zafar Ali demonstrates how to connect OBIEE to the world beyond Oracle.

Question of the Day
Changing the Schema
I set up a few users on my SQL Server 2022 instance.
CREATE LOGIN User1 WITH PASSWORD = 'Demo12#1' CREATE USER User1 FOR LOGIN User1 GO CREATE LOGIN User2 WITH PASSWORD = 'Demo12#2' CREATE USER User2 FOR LOGIN User2 GO CREATE LOGIN User3 WITH PASSWORD = 'Demo12#3' CREATE USER User3 FOR LOGIN User3 GOI then created a schema that one of them owned. Under this schema, I added a table with some data.
CREATE SCHEMA MySchema AUTHORIZATION User1
GO
CREATE TABLE Myschema.MyTable(myid INT)
GO
INSERT MySchema.MyTable
(
myid
)
VALUES
(1), (2), (3)
GO
SELECT * FROM MySchema.MyTable
GO
I granted rights and verified that User2 could access this table.
GRANT SELECT ON Myschema.MyTable TO User2 GO SETUSER 'USER2' GO SELECT * FROM MySchema.MyTable GOThis worked. Now, I move this schema to a new user.
ALTER AUTHORIZATION ON SCHEMA::Myschema TO User3; GOWhat happens with this code?
SETUSER 'USER2' GO SELECT * FROM MySchema.MyTable GOSee possible answers
