SQL & PL/SQL :: Getting DISTINCT Count From Two Different Columns?

Feb 1, 2012

I have following query which gives currency code from two different tables. I would like to get the distinct count of currency codes from these two different columns.

SELECT eb.person_seq_id, eb.bonus_amount, eb.currency_cd, ed.currency_cd_host
FROM fr_emp_bonuses eb, fr_emp_details ed, fr_periods p
WHERE eb.person_seq_id = ed.person_seq_id AND ed.period_seq_id = eb.period_seq_id
AND ed.period_seq_id = p.period_seq_id AND p.period_status = 'CURRENT'
AND eb.bonus_amount >= 0 AND eb.person_seq_id = 3525125;

This query gives following result

3525125240000USDINR
35251250 USDINR
352512560000 USDINR
352512550000 USDINR

There are two distinct currency codes (USD, INR) and total amount is 350000. So I am looking for a query to give me the following result

3525125350000 2

SQL & PL/SQL :: Count Distinct Rows In Table

Feb 21, 2013

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
4222253

SQL & PL/SQL :: Distinct And Individual Records In Single Or Minimum Pass(es)

Feb 21, 2012

I have following data

select rowid,object_name,object_type from do;

ROWID OBJECT_NAME OBJECT_TYPE
------------------ ------------------------------ ------------------
AAA/wuAAHAAAW73AAA CON$ TABLE
AAA/wuAAHAAAW73AAB I_COL2 INDEX
AAA/wuAAHAAAW73AAC I_USER# INDEX
AAA/wuAAHAAAW73AAD C_TS# CLUSTER
AAA/wuAAHAAAW73AAE I_OBJ# INDEX
AAA/wuAAHAAAW73AAF I_CON2 INDEX

6 rows selected.

I want it in the following manner

select rowid,object_name,object_type from do;

ROWID OBJECT_NAME OBJECT_TYPEGROUP
------------------ ------------------------------ ---------------------------
AAA/wuAAHAAAW73AAA CON$ TABLE2
AAA/wuAAHAAAW73AAB I_COL2 INDEX1
AAA/wuAAHAAAW73AAC I_USER# INDEX1
AAA/wuAAHAAAW73AAD C_TS# CLUSTER1
AAA/wuAAHAAAW73AAE I_OBJ# INDEX1
AAA/wuAAHAAAW73AAF I_CON2 INDEX1

6 rows selected.

Here the GROUP is changing when the data type is changing and thus for same data type the group shall remain the same As of now this is achieved by - first selecting distinct object_type, then it's mod(rownum,<input variable) and this result of 'mod' is doing the grouping which is the retrieved along with rowid of all individual record

Present query is as following and it is not much efficient

SELECT DO.ROWID RWID, RID
FROM DO,
(
SELECT OT,CASE MOD(ROWNUM,:v) WHEN 0 THEN :v ELSE MOD(ROWNUM,:v) end as RID
FROM(
(SELECT DISTINCT OBJECT_TYPE OT

[code]....

I tried using sequence with cycle but it gave different results. Even I tried following but it did not gave satisfactory results

select d.rowid,d.object_type,x.x1 from do d,(select distinct object_type,mod(rownum,:v) x1 from do where
created>'01-jan-2008')x where d.object_type=x.object_type and created>'01-jan-2008';

In short the query needs Distinct with mod(rownum) and individual records in a single pass The mod(rownum) i.e. group shall change when the object_type changes but then shall remain constant through out the particular object_type.

SQL & PL/SQL :: Count Of Records In Item List

Apr 17, 2012

One of the tables is having

COUNT(1)

To fetch the count using the above query , it takes 6 mins. There are no other processes running in the DB. The fragmentation % on this table is showing 16.3%

I tried finding the fragmentation using the below query.

select table_name,

round((num_rows*avg_row_len/1024),2) "actual data in table kb",
round((blocks*8),2)- round((num_rows*avg_row_len/1024),2) "wasted space kb",
((round((blocks*8),2)- round((num_rows*avg_row_len/1024),2)) / (round((blocks*8),2)) ) *100 "percent fragmented"
from dba_tables
where table_name like ITEM_LIST%'
and owner = 'TEST_USR'
and blocks != 0
order by 4 desc

TABLE_NAME table size kb actual data in table kb

Getting Count Of Records / Returning Zero For Null Results?

Jul 23, 2009

I'm needing to return results per month counting records that meet a certain criteria. Some months there will be no results but I need to return a zero rather than having that month omitted from the result set.

This is the pre-existing query:

SELECT TO_CHAR(CRSCHED_DATE,'YYYY/MM'), Count(CPMA.RECORDNUMBER)
FROM CPMA.CPMA CPMA
WHERE (CPMA.CRSCHED_DATE Between TRUNC(ADD_MONTHS(SYSDATE,-12),'MM') And LAST_DAY(ADD_MONTHS(SYSDATE,-1))) AND (CPMA.CHGSTATUS='Duplicate')
GROUP BY TO_CHAR(CRSCHED_DATE,'YYYY/MM')
ORDER BY TO_CHAR(CRSCHED_DATE,'YYYY/MM')

The results returned are accurate, but any month(s) with no records meeting the specified criteria are skipped in the result set.

SQL & PL/SQL :: Identify / Count Records In Ref Cursor Without Actually Fetching?

Jan 22, 2013

/* Formatted on 22/01/2013 19:32:50 */
CREATE OR REPLACE PROCEDURE test_rdm_miles (
p_ref_cursor OUT SYS_REFCURSOR
p_success NUMBER)
IS
BEGIN
OPEN p_ref_cursor FOR
SELECT 5168 mem_uid,

[code]....

I have a Procedure with out parameters as a REF CURSOR and response message as p_success.This ref cursor will be returned to the calling service. Is there a way in oracle by which we can identify whether the Ref cursor holds data without actually fetching it. Since if i choose to fetch the data, i will lose one row when i return the ref cursor back to the calling service Or else is there way i can retrieve the row i lose during fetch.

Other alternative what have been suggested is create an object type ,fetch the ref cursor values in object type. Then i can use the ref cursor to return the data by table casting.

one more solution is

OPEN
FETCH
CLOSE
OPEN (AGAIN) { this will lead to redundancy)

Get Count Of Records Grouped By Another Field From Transactions Table

Nov 5, 2009

I have a table that cannot be changed with a field called transaction_reference in the transactions table. This field contains any number of some values in a look-up table called codes.

The table codes contains 'AA', 'BB', 'CC'.

A typical transaction_reference field may look like 'CC BB' or 'AA' or 'AA CC' or 'AA CC BB' - any number, any order.My goal is to get a count of records grouped by another field from the transactions table.

Transactions table example:
transaction_id | transaction_reference | family
---------------------------------------------
1 | AA BB | foo
2 | BB CC | bar
3 | BB | hello
4 | AA CC BB | foo
5 | BB AA | bar

So the results should look like:

family | code | count
foo | AA | 2
foo | BB | 2
foo | CC | 1
bar | AA | 1
bar | BB | 2
bar | CC | 1
hello | AA | 0
hello | BB | 1
hello | CC | 0

If the counts of 0 (like the third to last and last line above) don't show up I'm ok with that.I put together an explode function like this one here but I'm really not sure where to go from here. I can split the transaction_reference, but I'm not sure what to compare it to or how.

I realize that a field in the transactions table for AA, BB, and CC would be ideal, but I can't do that... the powers that be won't let me change the table.

for each exploded segment from transaction_reference
look for it in the codes table
if it exists, add 1 to the count

PL/SQL :: Create View Which Is Aggregate Count Of Member Records / Grouped By Business_unit / Gender / Age Per Year

Oct 13, 2012

Using Oracle 11g...We have a table in our database of data with the following information:

MASTER_RECORD,
MEMBER_RECORD,
BUSINESS_UNIT,
GENDER,
DOB (date),
age [at time of month_record],
MONTH_RECORD (date) [31-MON-YEAR for recorded active month]

The table has ~55 million records. Existing index is only on MASTER_RECORD.There is now a need to create a view which is an aggregate count of member records, grouped by business_unit,gender, age per year. eg:

business_unit, gender, age, month_record, num_of_members -> for every combination
unit5, F, 25, 31-JUN-2011, 622
unit3, M, 18, 31-MAY-2011, 573

The view can be created now, but, is not fast enough to be reasonably considered a view. This table is re-created every month from a procedure, so there is flexibility on how it is created. Use interval partitioning by year( something I have not experienced using), create an index on the month_record,then create view.
