I have tried to execute this query
select partition_name, num_rows from dba_tab_partitions where table_name='Partisi_Book_Issue';
it display 0 num_rows. But i have made non partitioned table to partitioned table with the same number of rows. how to display number of record in each partition in any table?
I think this is easier than I think but all I want to do is count the distinct rows in a table.
WITH data AS
(SELECT 1 id1, 1 id2, 111 val1
FROM dual
UNION ALL
SELECT 1, 2, 222
FROM dual
UNION ALL
[Code]..
seems to get what I want
ID1VAL1CNT1
111114
212224
321114
422224
but can the count be done in a stand alone query such as??
SELECT DISTINCT id1,
val1,
COUNT(*) over() cnt1,
COUNT(*) over(PARTITION BY id1) cnt2
FROM data
ORDER BY id1, val1
NOT what I want
ID1VAL1CNT1CNT2
1111152
2122252
3211153

I have a table that partitioned into six partitions. each partitions placed in different table space and every two table space placed it on a different hardisk
when I will do query select with the non-partition keys condition, how the search process ? whether the sequence (scan sequentially from partition 1 to partition 6) or partition in a hardisk is accessed at the same time with other partition in other hardisk. ( in the image, partition 1,4 accessed at the same time with partition 2,5 and 3,6)
Can i alter the table to create partition on non partition table, i have tried and could not create it. Do we have some other means to do it as this is the live table and cannot drop them else will lose the data.

where conditions:
1)need to take the count of rows(col1).where col2 value is 3 or 2 .
2)value 3 or 2 is extracted and conditioned in the query
I need to get the number of rows based on one condition for certain time period. For example, writing a query for 3(any) hrs , i need to get the output as count of rows as hourly basis. Like these:
Date Time Count
12/08/2010 16:00 234
12/08/2010 17:00 345
12/08/2010 18:00 645
I want to create a SELECT, that shall give back only a special amount of rows, depending on the sum of one of the selected fields.
At first a code sample of the complete selection:
SELECT DISTINCT mnr, ktxt,
(SELECT Sum(meng_4)FROM reldb d1 WHERE d1.mnr=d.mnr)qty
FROM reldb d
WHERE mnr IN (SELECT mnr FROM relac WHERE Lower(rlnr) NOT LIKE 'platte geprägt%')
AND saext='M'
ORDER BY qty DESC,ktxt;
This selection produces some lines of output (in my case i.e. like 300). What I want to see is only that much lines that the condition 'sum of all items listed below meng_4<=sum of all items meng_4 of the whole selection * 0.9' is fulfilled.
So, if the whole selection produces a total of 10000 as sum for all items meng_4, I want to see only that amount of rows that sums a total of at least 9000 for all items meng_4.
I hope, this specification is exactly enough to understand my intent.
1. Can I do this in a query?
2. If yes, what would this query look like?
from within plsql i am doing
insert into t_target (...) select (fiels,fields,fiels) from sourcetable;
commit;
i want to capture number of rows committed and assign it to a variable or insert it into a table, i can not rely on count of source table or t_target because both those tables are changing through out of the day/ data are being inserted and removed from those tables. is this possible
My problem is i need to display the status and the record count in separate rows.How can i do it
Example
SELECT 'A' STAT, COUNT(A) CNT,'B' STAT, COUNT(B) CNT,'C' STAT, COUNT(C) CNT
FROM TAB1;
OUTPUT SHUD BE LIKE
STAT COUNT
A A_cnt
B B_CNT
C C_CNT
I need to list a count of rows where a DATE field is not null and group those counts by day.
Here's my sql so far...
SELECT
COUNT(DQ_DISTRBTN_DATE) as DQR_DIST,
DQ_DISTRBTN_DATE as DIST_DATE
from
ETL_PROCESS.BATCH
group by
DQ_DISTRBTN_DATE;
Because DQ_DISTRBTN_DATE contains time, how do I modify to achieve the desired result?

I want to use Javscript or a Dynamic Action to "count" how many selected rows there are, when a UPDATE button is pressed. Right now, the UPDATE button "submits" the page, then a page item computation runs the following code to get a count:
DECLARE
v_cnt number(9);
BEGIN
v_cnt := 0;
FOR i in 1..htmldb_application.g_f01.count
LOOP
v_cnt := v_cnt + 1;
END LOOP;
return v_cnt;
This works... but I dont want to submit (and rerun the report) just to get this count.
I have copied this loop into a Dynamic Action using the Click action of the UPDATE button, but it doesnt seem to recognize htmldb_application.g_f01.count .. so my value returns as 0.

I am using Oracle 11.2.0.1 Oracle Database.I have a table with 10 Million records and it's a Non Partitioned Table.
1) I would like to partition the table (with partition by range ) without creating new table . I should do it in the existing table itself (not sure DBMS_ REDEFINITION is the only option ) (or) can i use alter table ...?
2) Add one partition which will have data for the unspecified range.
i have table with range partition and list sub-partition..can i add one more list sub-partition if it is not possible , i have to drop first sub-partition.

how to partition and index my table for a special problem.
The table:
CREATE TABLE TEST (
ID NUMBER PRIMARY KEY,
U_VALUE NUMBER NOT NULL, -- Ranges from 0 - 30.000.000
O_VALUE NUMBER NOT NULL, -- Ranges from U_VALUE - 30.000.000
CREATE_TS TIMESTAMP DEFAULT SYSTIMESTAMP NOT NULL,
UPDATE_TS TIMESTAMP NOT NULL,
ITEM_TYPE NUMBER NOT NULL --<< Only 4 different values >>
);
As you can see, U_VALUE is ALWAYS lower than O_VALUE.I need to have the CREATE_TS in either main- or subpartition do drop the partitions after some time so i don,t have to use DELETE statements. The table has 360 millions rows.
The application has only 8 query which will always use a WHERE clause like this:
SELECT * FROM TEST
WHERE U_VALUE <= :1 AND O_VALUE => :2 AND ITEM_TYPE = :3
1. Is there any good technique how to create a good index for the queries (application will execute 120 queries per second)?
2. how to partition this table?
