Please help with the query creating Materialized View
Hi,
We are using the below query to create a Materialized View but it has been running since 3 hours. It is an Oracle 9i database running in HP-UX.The quey is as follows,

UPDATING the query in materialized view
Hi,
i have a little doubt in Materialized view. i created a materialized view and log with the following query,
create table test_mv (a number ,b number )
alter table test_mv add constraint t_pk primary key ( a );
insert into test_mv values (1,2);
insert into test_mv values(2,2);
insert into test_mv values(3,2);
insert into test_mv values(4,2);
insert into test_mv values(5,2);
commit;
CREATE MATERIALIZED VIEW LOG ON test_mv
WITH SEQUENCE, ROWID
*(a,b)*
INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW product_sales_mv
ENABLE QUERY REWRITE
AS SELECT b from test_mv;
Now i want to update the query in the MV as 'Select a from test_mv' . for that i tried with
*'ALTER MATERIALIZED VIEW product_sales_mv AS SELECT a from test_mv;'*
But it throwing error,
Error starting at line 5 in command:
alter MATERIALIZED VIEW product_sales_mv AS SELECT b from test_mv
Error report:
SQL Error: ORA-00933: SQL command not properly ended

*Cause:+
*Action:+
i guess i am doing wrong. kindly help me here. i want to update it without drop and recreate.
thanks,
Jeevanand.KeHi Jeeva,
No. you cannot add or drop columns to the materialized view using the ALTER Statement.
To Change the Structure of the view , drop and re-create the materialized view.
To Alter a materialized view log, You can use the ALTER MATERIALIZED VIEW LOG. By this,
You can add new columns to a materialized view log.
ALTER MATERIALIZED VIEW LOG ON sggi_mrps.emp ADD(deptno);Thanks,
Shankar

I need help with SQL query (if it can be accomplished with query at all).
I'm going to create a table with structure similar to:
Article_Name varchar2(30), Author_Name varchar2(30), Position varchar2(2). Position field is basicly position of an article author in the author list, e.g. if there is one author, his/her position is 0, if 2, then 1st author is 0, second is 1, etc.
Article_Name Author_Name Position
Outer Space Smith 0
Outer Space Blake 1
How can I automate creation of Position, based on number of authors on the fly? Let's say I have original table without Position, but I want to create a new table that will have this information.
RegardsIf you have an existing table whose structure doesn't tell you what position the author is in, what's the algorithm you'd use to determine who was the first author, the second author, etc? If you issue a select query on a table without providing an "order by" clause, Oracle makes no guarantees about the order in which it retrieves rows.
As an aside, why would you store position number in a varchar2 field? If it's a number, it ought to be stored as a number.

Need urgent help with the query - Beginer
Hello - I need help with a query to populate data in a table.Here is the scenario.
Source1
MnthID BranchCod CustID SegCode FXStatus ProfStatus Profit
200712 B1 C1 20 Y Y 100
Source2
MnthID BranchCod CustID ProdCode ProdIndex
200712 B1 C1 12 1
200712 B1 C2 12 0
Destination
MnthID BranchCod SegCode ProdCode CountSegCust CountProdCust ProfitProdCust
Condition and Calculations:
1)Source1 customer are base customers.If Source2 has customers who is not in source1 then that customer's record should not be fetched.
2)SegCode, FX Status, ProfStatus is one variable in destination table. [ SegCode = SegCode+ FXStatus (if FXStatus = Y)+ ProfStatus (if FXStatus = Y) ]
3)CountSegCust = CountCustID Groupby MnthID,BranchCod,SegCode Only.
4)CountProdCust = CountCustID Groupby MnthID,BranchCod,SegCode,ProdCode (when ProdIndex = 1)
5)ProfitProdCust = Sum of Profit of Customers Groupby MnthID,BranchCod,SegCode,ProdCode (when ProdIndex = 1)
Apologies for bad formatting.
Thanks in advance!!A total guess indeed.
It's not clear whether some aggregation can be done (summing counts of grouped data might cause some customers being counted more than once)

Help needed in query for Materialized View
Hi,
I want to create a materialized view which has some precalcultaed values.
I have four dimension tables out of which one is a Time Dimension table with levels as Year->Quarter->Month.
The precalculations are the moving averages and cummulative values of Sales Amt on the dimension values over a period of 4 Months.
The dimension tables are Clients, Products, Channel, Time.
Fact Table is Sales_Fact which will have the sales amount for different members of the dimension.
Since my fact table is very huge, i want to create a materialized view where i could store the required calculated measures, here Moving Average of Sales Amt for each Client, Product, Channel dimensions over a period of 4 Months.
Can anybody help with writing the query for this..Any help in this regard will be appreciated..
Please give me suggestions for this..Check this link.

hello all!
please, help me again.
we have a foreign key discrepancy and my task is to create a view which will show the 3 aspects.
Let's we have 3 schemas: A - good (which means that i will compare WITH A, source)
B and C are bad (which mean that I will checking this schemas).
So, i need to obtain:
1) FK that DO NOT exist in B&C and do exist in A
2) FK that DO exist in bad schemas (B&C) but DO NOT exist in good schema (A)
3) FK's that exist in both (A&B, A&C) schemas on the SAME TABLE, have THE SAME CONSTRAINT_NAME but are on the DIFFERENT columns.
the first and second I seem to be done through the
select CONSTRAINT_NAME, TABLE_NAME, STATUS from dba_constraints where owner='PRIV_MD' and CONSTRAINT_TYPE='R' and CONSTRAINT_NAME
2 NOT IN (select CONSTRAINT_NAME from dba_constraints where owner ='MSA_MD'); (to get the second task we just reversing owners in query and subquery)
query. but the third one is really pain in my back. i have a query:
SELECT a.column_name, b.column_name FROM dba_cons_columns a, dba_cons_columns b, dba_constraints c, dba_constraints d
WHERE c.CONSTRAINT_TYPE='R'
AND a.CONSTRAINT_NAME = b.CONSTRAINT_NAME
AND a.CONSTRAINT_NAME = c.CONSTRAINT_NAME
AND b.CONSTRAINT_NAME = d.CONSTRAINT_NAME
AND a.owner = 'PRIV_MD' AND b.owner = 'MSA_MD';
which runs hours and returns million of rows with the two columns with the same names... but if i'm adding
AND a.column_name != a.column_name (i'm not sure it's a correct syntax)
line it returns "no rows selected"
please, help me obtain it, i'm fighting already the second day..
(please, don't be angry, i'm just learning and this is my first task on my work...)This is basically just a UNION ALL (the constraint columns from both schemas)
MINUS what exists in both (the INTERSECTion)
I made it a little more complicated so you could see in which schema the column is used. You could use exactly the same approach for your questions 1 and 2 also.
SELECT * FROM
(SELECT a.column_name,c.constraint_name,'salive' schema_containing
FROM dba_cons_columns a
INNER JOIN dba_constraints c ON a.CONSTRAINT_NAME = c.CONSTRAINT_NAME
WHERE a.owner = 'SALIVE' and c.constraint_type = 'R'
UNION ALL
select b.column_name,d.constraint_name,'satest'
FROM dba_cons_columns b
INNER JOIN dba_constraints d ON b.CONSTRAINT_NAME = d.CONSTRAINT_NAME
WHERE d.CONSTRAINT_TYPE='R' AND b.owner = 'SATEST') u
WHERE NOT EXISTS
(SELECT *
FROM
(SELECT a.column_name,c.constraint_name
FROM dba_cons_columns a
INNER JOIN dba_constraints c ON a.CONSTRAINT_NAME = c.CONSTRAINT_NAME
WHERE a.owner = 'SALIVE' and c.constraint_type = 'R'

FROM dba_cons_columns b
INNER JOIN dba_constraints d ON b.CONSTRAINT_NAME = d.CONSTRAINT_NAME
WHERE d.CONSTRAINT_TYPE='R' AND b.owner = 'SATEST') i

Please Help - How do I create a VIEW through a trigger
I'm trying update a view under the following circumstances
I have a table, TABLE1, with about 50 columns. I have another table, TABLE2, with a list of columns from TABLE1 that I want to include in the view. Whenenver I add or delete an entry in TABLE2, I want to update the view with the new set of columns from TABLE1.
I'm getting "cannot commit in trigger" (ORA-04092) error.
Please help
I tried the following trigger and the procedure
TRIGGER
CREATE OR REPLACE TRIGGER MAPPING_FIELDUPDATE
AFTER insert or DELETE OR update of DISPLAY_COLUMN_NAME, TABLE1_COLUMN_NAME
on TABLE2
begin
TABLE1_MAPPING;
end;
Procedure TABLE2_MAPPING
IS
CURSOR MYCUR IS SELECT * FROM MYDATBASE.TABLE1;RowInfo MYCUR%ROWTYPE;
FIELDLIST VARCHAR2(5000);
SQLSTRING VARCHAR2(5000);
BEGIN
OPEN MYCUR;
LOOP
FETCH MYCUR INTO RowInfo;
EXIT WHEN MYCUR%NOTFOUND;
IF (FIELDLIST IS NULL) THEN
FIELDLIST :=RowInfo.TABLE1_COLUMN_NAME||' '||RowInfo.DISPLAY_COLUMN_NAME;
ELSE
FIELDLIST :=FIELDLIST||','||RowInfo.TABLE1_COLUMN_NAME||' '||RowInfo.DISPLAY_COLUMN_NAME;
END IF;
END LOOP;
CLOSE MYCUR;
SQLSTRING:= 'CREATE OR REPLACE VIEW SELECTTABLE1 AS SELECT '||FIELDLIST||' FROM TABLE1';
DBMS_OUTPUT.PUT_LINE(SQLSTRING);
EXECUTE IMMEDIATE SQLSTRING;
END;or does anybody know any work-around.Sure. Don't use a trigger to create a view. Build a view that selects from a function that returns a ref cursor. Have the function assemble the query dynamically from the values in TABLE 2.
Although I still think this kind of dynamic configuration is a design smell.

Hi ,
Below query is taking more time (4mins) for 41 rows returning and there is no full table scan .Can some one help to rewrite the query.

We have these two tables and trying to see if the amount in one table is equal to the sum of the amount fields in another table.
Can someone please help?
SQL> desc test;
Name Null? Type
KEY NUMBER(9)
AMOUNT NUMBER(11,2)
SQL> desc test1;
Name Null? Type
KEY NUMBER(9)
TOTAL_AMOUNT NUMBER(11,2)
SQL> select * from test;
KEY AMOUNT
1 10
1 20
1 70
3 rows selected.
SQL> select * from test1;
KEY TOTAL_AMOUNT
1 100
1 row selected.
SQL> select count(*) from test1 a where exists(select 'x' from test b where
2 a.key=b.key and a.total_amount!=sum(b.amount));
a.key=b.key and a.total_amount!=sum(b.amount))
ERROR at line 2:
ORA-00934: group function is not allowed hereHi,
This would be so easy if there was a table like test that only had one row per key!
You can make such a table, or you can just make a sub-query that has all the same data, and use that sub-query as if it were a table.
For example:
WITH one_row_per_key_test AS
SELECT key
, SUM (amount) AS total_amount
FROM test
GROUP BY key
SELECT COUNT (*)
FROM test1 a
WHERE EXISTS
SELECT 'x'
FROM one_row_per_key_test b
WHERE a.key = b.key
AND a.total_amount = b.total_amount
);There are lots of other ways to solve this particular problem (including HAVING), but this is a very important technique to know. -
Please help with RecordSet Query
Hello all. I am trying to build a contact management system
for different offices. Each person has a login they use to access
their office's respective page. What I am wanting to do is pull up
all the employees' information that work at the same location as
the person who logged in. For example: Person A, B, and C work at
Location 1 and Person X, Y, and Z work at location Z. If person A
logs in, I want the to be able to see the dynamic table with the
information for all of Location 1 (Person A, B, and C). I
understand using the session variable MM_Username to filter the
recordsets based off who logs in. Where I'm confused is in pulling
up the records for everyone that shares the same location as the
person who logs in. In other words, if I say filter Information
based off Session Variable MM_Username it only returns the
information for the person who logged in. I want it to say, in
layman terms, Person A logged in, now look at their location, and
return all Person's information who has a location equal to that of
Person A. I hope I explained my dilemma clearly enough. If I need
to elaborate or explain any more please let me know. Thanks in
advance for any and all help.Thank you for your help. Sorry for my ignorance, but I'm
still confused. I've made some changes to hopefully help. I have 1
SQL table (called "Employees") with TableID, Username, Password,
AccessLevel, and LocationID. I have another table (called
"Names"-for testing purposes) with just TableID, Name, and
LocationID. The query that I built, which doesn't work, is:
SELECT `Names`.`Names`
FROM Employees, `Names`
WHERE Employees.Store_Number = `Names`.Store_Number
I'm wanting it to simply display the names from the Names
table that share the same LocationID as in the Employees Table. I
realize that at this point it should just be a list of all the
employee names from the Names table, but what it's doing is
actually displaying 2 of every name. What do I need to do to set
this up to where the MM_Username Session Variable generated at
login grabs the LocationID from the Employee Table, then uses that
LocationID and displays all the names from the Names Table with
that same LocationID? I'm sorry for my lack of understanding, and I
really appreciated the help.
As a side note, why are there apostrophes around the Name
Table but not the Employees Table in the query window? Thank you
again.
