Hi,

I am gettting error ORA-12014 when creating a MV on local table with complete refresh. Not on MV log create. Sounds strange. Primary key cannot be created on this table. I do not need fast refresh anyway. Why does it need PK for complete refresh. I tried creating a MV log with rowid option on the table and that did not help either. Any workaround.
Is there any issue with creating a MV on a MV. For some reason access is not available to the original table.
For getting sql being executed by a session I generally use v$sqlarea.sql_text by joining it with address. However, I see that sometimes if a session is doing DDL like create I cannot get it. Is there some other way of getting ddl. Especially in case of heavy load and trying to find out what a long running session is doing.
What is the difference between Number and decimal datatype : Manual says : DECIMAL A decimal number with up to 15 significant digits.

NUMBER
A decimal number with up to 38 significant digits. When I specify DECIMAL in the create table and then look at describe table I see it creates it as NUMBER. On 9i. So is it synonymous or is there something DECIMAL can do that NUMBER cannot or vice versa.

5) I have schema schemaA which has a table tableA, tableB. Another schema schemaB has a view viewA selecting from these tables. There is user userC who needs to select from view viewA. I gave grant on schemaA tables to schemaB with "grant option". Then select on viewA was granted to userC. Did not work. : error : ORA-01031: insufficient privileges
Then after long struggle I gave select any table select any dictionary to userD. It works with just those two privs. Howver if I grant select on viewA to userC it does not work. STrange.

Please help on any of the above items. Sorry about too many Q. Thanks for help.

Thanks
