SQL & PL/SQL :: PCT Is Not Enabled While Creating Mview / Though Base Tables Are Partitioned
Apr 4, 2011
I created a mv for one of the partitioned tables but on viewing the mv capabilities it still shows PCT is set to 'N'.
create materialized view MV_summary_SEC
refresh fast
start with sysdate
nEXT SYSDATE + 1/24
enable query rewrite as
[code]....
If i remove the sub query and create the mview like this,then PCT is enabled.
create materialized view MV_summary_SEC
refresh fast
start with sysdate
nEXT SYSDATE + 1/24
enable query rewrite as
select PERIOD , SUM(SUM_WEB_HITS)
from summary ,date_table
where PERIOD >= DATE_TABLE.CUR_DATE
group by PERIOD
Is it simply because oracle doesn't support PCT if the definition contains subqueries ?

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'm currently having a problem with regards to Exporting data to another server. This is the Scenario:Source Server is Production Server with all of its Tables in the Schema are Version-Enabled.
Destination Server is a Test Server.I exported data from Production Server using EXP command. Then in my Test Server I imported my data using IMP command (I already created tablespace and user for the Schema).Import is successful in my Test server but when I execute my queries, There are no rows returned.
I checked my _LT tables and it contains my data. but when I query from the View created when version was enabled, no result is returned.Am I missing something when I exported and imported my Schema? Should I have included the WMSYS schema when I created the .dump file?

I would like to ask about indexes in partitioned tables.I have indexes on a partitioned table, it is partitioned by range method i.e based on Creation date time.All select queries sent to the table use the Creation date time. I have an index on Creation date time.Here is an example:
SELECT col1, col2, col3
FROM table1 where
date_time BETWEEN TO_DATE ('20120117 10:00:00','YYYYMMDD HH24:MI:SS')
AND TO_DATE ('20120117 13:00:00','YYYYMMDD HH24:MI:SS')
AND frmt_name = 'XXXX'
AND sender = 'YYYYY'
AND nature = 'ZZZZ'
AND type LIKE '548'
ORDER BY date_time
WHERE ROWNUM <= 5000
[code]....
do I have to add DATE_TIME to all indexes (IX_NAME_FORMAT_TYPE,IX_CCY) or not?

understand on the below regarding partitioning table and indices.
1. How to know if each partition have LOCAL index or Global index?
I had the above question duw to the beloe reason :
I have a table with 130 partitions and 7 indices. When checked the DBA_IND_PARTITIONS it lists down only 1 index name (which distinct) for all the 130 partitions.
Does it mean it is a Global index? If Global index, is it partitioned? How to get those information?
2. Assuming, if i have LOCAL indices for every partitions, from where i shall nail down the name of each local index and how would i get the detail of referencing Global index?
3. By which type a table was partitioned? LIST,HASH,RANGE ?

we are looking to use oracle 11g as a log database using partitioned tables.
- The tables will have only a 3-5 columns of ~varchar(50) size
- We are looking at a volumn of ~33million rows (inserts) per day.
1) Will partitioned tables be able to handle this type of volume?
2) if yes, will a Composite Partitioning (using last modified datetime as range) then subparition with range be the best choice?
if this type of volume is too high for 11g, what are some of the alternative products we can use.

that are my biggest tables
Users use front end (called ESS Console) and when they try to open one of those tables they wait very long (really bad performance). Sometimes the GUI even hanging without displaying results.
Does Partitioned Tables feature works for better performance?

I have created a softlink to a data file orig_file.dat using the command ln -s orig_file.dat orig_file_link.dat
Now is it possible to create an external table using this linked file orig_file_link.dat
I am using this linked file to minimise the space usage because every month we get different data files and external table creation is done as a batch job copying the data file to another file whenever a new data file arrives. External table is created with the new file. so i need to check whether it is possible with the linked file instead of copying the file.

I am facing a problem while creating a program using oracle forms.These two table i am using in creating following program .
SQL> desc electricity ;
Name Null? Type
----------------------------------------- -------- ----------------------------
ID NOT NULL NUMBER
NAME VARCHAR2(40)
PREV_READING NUMBER(20)
PRESENT_REDAING NUMBER(20)
TOTAL_UNITS NUMBER(30)
AMOUNT NUMBER(30)
[code]....
What i want that whenever user writes a value in "PRESENT_Reading" Column then it stores value in "ID table" .For example if current month is July ,Then when user write a value in present Reading column ,it stores it in JULY Column of Id table ..i Write following trigger (Key_commit) On present_reading Column .
if sysdate=to_char(sysdate,'MON','Jan') Then
:electricity.PRESENT_REDAING := :ID.Jan ;
elsif
sysdate=to_char(sysdate,'MON','FEB') Then
:electricity.PRESENT_REDAING := :ID.Feb ;
elsif
sysdate=to_char(sysdate,'MON','MAR') Then
:electricity.PRESENT_REDAING:= :ID.MAR ;
But when i run my form it does not work ,and raised unhandled Exception .I think i need to change some properties of PRESENT_READING column of electricity table.

I'm having trouble with a little assignment.
"Create a view named vuPassFailRate that will show the pass rate and fail rates of each test."
I have a table named Test_ID containing the following columns:
TEST_ID
TEST_NAME
PASSING_GRADE
And another table named Test_History containing the following columns:
TEST_ID
STUDENT_ID
SCORE
I'm assuming i have to create an inline view, and to work out the pass/fail rates i need to do something along the lines of (For pass rate) Where SCORE is greater than or equal to PASSING_GRADE, and TEST_ID equals TEST_ID, divide by a count of SCORE and multiply by 100. I just cant work out the nested select statements, and work out the formula using two columns in two tables.
I have been staring at this problem for so long now i cant see the wood for the trees.

I am trying to restore to a backup instance on a backup server. When I try to recreate the tables I keep getting ORA-01659: unable to allocate MINEXTENTS. The tablespaces and datafiles on both servers show as the same size in OEM.
I have dropped all tables and OEM shows tablespaces are empty. Then I run a script to recreate all tables. Most of the tables don't get created because their TS is full. After the script to recreate all tables runs, the main tablespaces are full, more full than on the production machine. I have also tried ALTER TABLESPACE xxx COALESCE; on each tablespace right after dropping all tables and before recreating them to reclaim free space. Why is it full? I've only dropped and created the tables, there shouldn't be any data in them yet.
ORA-01659: unable to allocate MINEXTENTS beyond 2 in tablespace PLUS_T...The backup instance was already there, all I did was drop the tables. Here's what I ran on prod to build a script to recreate the tables on backup server. Got it off Burleson somewhere.
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name) ||'; '

I am writing a procedure that will be called from a java wrapper.
The procedure do a lot of data manipulations and in between i am creating global temp table and saving the data into it for each request thats given as a parameter to the procedure. After all the processing i have to write the data from this global temp table into a physical table and atlast drop the temp table.
Create or replace proc_name ()
update table........
delete from ..........
CREATE GLOBAL TEMPORARY TABLE TSAAG
( supplier_id numeric(10) not null,
supplier_name varchar2(50) not null,
contact_name varchar2(50)
)
insert into............
drop table TSAAG;
End;
creating a global temp table inside a procedure is expensive...
Do we have anything like creating table before and calling the instanse of it in procedure.
Do we have any alternatives to this..

You can only have a materialized view in one refresh group? What options to I have to refresh it in different intervals?

We have created this Mview in two schemas i.e.MRD and MRDSEIn MRD schema we are getting the date format is MM/DD/YYYY where as in MRDSE we are getting the format DD-MON-YYYY. why we are getting the difference in date format in two schemas.We are not modifying any thing.
Here is DATAENCRYPTION Package.
ENCRYPTDATA Function.
We are getting this date format issue only for the ENCRYPETED date columns in MRDSE.
