I'm trying to create a Materialized View on a remote database from a simple view. The reason is, the data owners don't want to grant explicit tables privileges to external subscribers.
A new schema is created to publish data in the form of a view. I've created mlogs on the master tables, and granted them to the subscriber, but it's still complaining about a missing primary key on the view. A primary key does exist in the master table.
Is there another work around for this situation without having to work inside the data sources' environment?
There are 2 databases, database A and database B. Database A is Oracle 11.2.0.2 which runs on linux and Database B is Oracle 11.2.0.2 which runs on windows xp machine. In database A, there are 100's of tables which are being updated every 10 minutes or 15 minutes. For reporting purpose, the developer wants to run report for the tables. But since database A is being updated every now and then, generating reports takes almost 15 to 20 minutes. So the reports can be generated in Database B. Once in a day the database B should have the updated data from database A so that the reports can be generated in database B with less time. What could be the best solution for the database B to have the updated data on daily basis from database A in oracle?
i have a union all query (two quiries i suppose) that runs fine and returns the results i am after.... when i try to use this query to create a view I get
SQL Command: CREATE OR REPLACE FORCE Failed: Warning: execution completed with warning
CREATE OR REPLACE FORCE VIEW "schema1"."name_of_view" ("column1", "column2", "column3") AS SELECT b.column1, a.column2, c.column3
H want to Create a view which reside in one instance for example xxx Instance . I want to create the same view which reside in xxx instance to another instance for example YYY Instance How to acheive this ?I tried desc the View take the view script from XXX instance and copied the view script to YYY instance when I compiled Iam getting an Error
For Example My view in XXX Instance CREATE OR REPLACE FORCE VIEW xxx.sample ( First_name, last_name ) as select "F_NAME", "L_NAME" FROM EMP;
When try to copy and compile the same view in my YYY Instance i am getting error
we have the following requirement for creating materialized view.
In database "DB1", a table "abc" is there in "user1" schema. In database "DB2", in "user2", we are accessing the "abc" through DB link "DBL1" to DB1: select * from user1.abc@DBL1; we have created a public synonym for "user1.abc@DBL1" as "sabc".
In database "DB3", we need to create the materialized view to access "abc" in DB1 through DB2. we are not allowed to access "DB1" directly from "DB3". so we create a db link as "DBL2" in "DB3" to "DB2".
when i try to create a materialized view as below: create materialized view abc_mv as select * from sabc@DBL2;
But got the error as "synonym translation invalid". When i access the SQL statement separately as below select * from sabc@DBL2, its working but in Materialized view, it shown that error. Even i tried with schema name as well like "user2.sabc@DBL2" , but that also thrown same error.
Is there any option available for this type of creating materialized view?
When i try to create a trigger , i ended up with error.
SQL> create or replace 2 TRIGGER LOGON_TRG AFTER LOGON ON DATABASE 3 BEGIN 4 INSERT 5 INTO 6 user_audit_log 7 SELECT 8 user#,
[code]....
Warning: Trigger created with compilation errors.
SQL> SQL> show error Errors for TRIGGER LOGON_TRG: LINE/COL ERROR -------- ----------------------------------------------------------- 2/5 PL/SQL: SQL Statement ignored 17/17 PL/SQL: ORA-00942: table or view does not exist
The command used to resolve the error is
GRANT SELECT ON v_$session TO jack;
Jack user has sysdba privilege. My question is 'sysdba' is a super and special user which has all the privileges in database. Then why does it need SELECT privilege on v$session to user to create the trigger?
I am trying to create a commit on refresh materialized view so that whenever I perform DML followed by commit on Master table it should get quickly reflect on my Materialized view. I have given SELECT on table privilege to user where this view will be created On Master:
GRANT SELECT ON HR.EMPLOYEES TO SCOTT. From Scott:CREATE MATERIALIZED VIEW scott.hremp REFRESH FAST ON COMMITAS SELECT * FROM HR.EMPLOYEES; ERROR at line 4:ORA-01031: insufficient privileges Then I Grant all on EMPLOYEES table to SCOTT. GRANT ALL ON hr.EMPLOYEES TO SCOTT; Then got following error while creating materilized view:SQL> CREATE MATERIALIZED VIEW scott.hremp 2 REFRESH FAST ON COMMIT 3 AS 4 SELECT * FROM HR.EMPLOYEES;SELECT * FROM HR.EMPLOYEES *ERROR at line 4:ORA-23413: table "HR"."EMPLOYEES" does not have a materialized view log I create materialized view log on Master:SQL> CREATE MATERIALIZED VIEW LOG on HR.EMPLOYEES;Materialized view log created.
Even after this I am not able to create materialized view and now getting Table not Exist error:
SQL> CREATE MATERIALIZED VIEW scott.hremp 2 REFRESH FAST ON COMMIT 3 AS 4 SELECT * FROM HR.EMPLOYEES;SELECT * FROM HR.EMPLOYEES *ERROR at line 4:ORA-12018: following error encountered during code generation for "SCOTT"."HREMP"ORA-00942: table or view does not exist. Also I want to know why I needed to GRANT ALL to HR for creating this materialized View.
we are trying to create a materialized view (MV) which would access the remote database through db link. Now we need to do update on the local MV so that it should be reflected on the master table.
There is no primary key on this table and we are using "complete refresh" option. since we dont have control over remote database, we are not allowed to create MV log over there.
in this scenario, if i try to create updatetable MV with complete refresh, we are getting below error:
SQL Error: ORA-12013: updatable materialized views must be simple enough to do fast refresh
I have a list of materialized views in schema A. I want to create a refresh group and then refresh it from Schema B (Dynamically-run time based on some criteria). What Grants are necessary on schema B in order for it to be able to create and refresh the groups on Materialized views in Schema A.
I know that one of the Options is to, GRANT ALTER ANY MATERIALIZED VIEW as a SYS user. But I do not have any SYS privileges.
I have a view on base tables holding historical data for previous 60 months(one table per month) with union all operators.create index on those base tables will improve performance or creating a primary key with disabled novalidate will improve for retrieving data?
The view has around 8 million data and used as a fact table with 4 dimension tables.A DTS package from MSSql side refreshes OLAP cube by retrieving data from these tables in oracle.
I am trying to create trigger through Procedure due to following reasons-
1. The name of the column on which trigger will execute, is to be fetched dynamically. 2. The name of the column to be updated, is to be fetched dynamically.
Here is the sample code-
CREATE OR REPLACE PROCEDURE test2 IS var VARCHAR2 (4000); uname VARCHAR2 (30); attribtask VARCHAR2 (100); mapcol VARCHAR2 (100); BEGIN [code].........
On execution, the procedure throws the error of 'Insufficient privileges'. The 'var' seems to be the main culprit because the issue disappears if var is set to 'select * from dual'. Also, if i take the output (value of var) given by DBMS_output.put_line function and execute it explicitly, trigger gets created.
In addition- The procedure is (and being executed) within the same user/schema under which trigger is going to be created.
declare v1str varchar2(100):='select empno,ename from emp'; v2str varchar2(100):='select empno,ename,sal from emp'; type t_array is varray(2) of varchar2(100);
[Code]....
So my problem is while executing the different sql statements by passing it to the procedure,how can the procedure would behave dynamically.It must be able to process all the sql statements.
I am writing this procedure with a explicit cursors defined in it. However when i compile the procedure i get this error: Error(39,1): PL/SQL: SQL Statement ignored Error(39,1):PLS-00394: wrong number of values in the INTO list of a FETCH statement .
I have to create a stored procedure having some 10 cursors and i have to display the data's fetched by select statement in cursors using dbms_output.put_line().
for ex: ------- CREATE OR REPLACE PROCEDURE PROC AS CURSOR C1 AS SELECT * FROM EMP; BEGIN FOR R IN C1 LOOP
[code].....
My question is while creating procedure i want to check if the object exist in database or not.
If EXIST NO PROBLEM MY CODE CREATE THE PROC AND EXECUTED FINE IF NOT EXIST
I don't want an exception to be thrown stating "OBJECT DOES NOT EXIST" I wanted PL/SQL engine not to execute the particular select statement itself and continue executing other select statements.
The reason why have such kind of wierd requirement is my program displays all the CEMLI objects in any 11.5.10 instance. I don't know whether they have installed discoverer or not. if they installed it no problem else my program have to eliminate.EXECUTE IMMEDIATE, REF CURSOR becoz i tried it and works fine.but not able to wrap in WRAPPER UTILITY 8.0 versions.
I am trying to get my stored procedures together again after many years of working on MS SQL server. I'm alternating between using SQL-Plus and Oracle SQL Developer for Mac. In SQL Developer - which I like to use - I keep getting errors at the point where the END command for the package header occurs and the create command for the package body starts.
I've found that if I run the following in SQL-Plus I'm OK but if I try it from SQL Developer I get a compile error such as following or else an error telling me that it expects function, or pragma or something to that effect:
Error(8,1):PLS-00103:Encountered the symbol "/"
The code is as follows: -------------------------------------- CREATE OR REPLACE PACKAGE MACR_SAMPLE_PROC_4 AS PROCEDURE sampleproc_4( pParam1 in integer, pParam2 out varchar2); END MACR_SAMPLE_PROC_4;
