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

Application Express :: Show Count From Another Table In A Report

May 29, 2013

I am using Apex 3.2...I have the following sql in a report

select
a.jobid jobid,
a.jobid related_jobs,
to_char(a.startdate, 'dd.mm.yyyy hh24:mi:ss') startdate,
to_char(a.enddate, 'dd.mm.yyyy hh24:mi:ss') enddate

from jobs aI would like to show a count from another table where the jobid = jobid from the above sql.The problem is I don't know how to refer to the jobid in my extra sql.Here is my extra sql for the new count column.

(select count(1)
from jobs a, loghead b, dba_scheduler_job_run_details c
where a.logid = b.logid
and b.session_id(+) = c.session_id
and a.jobid = :P3_JOBID) no_of_related_jobs.

This will not work because :P3_JOBID is a page item.I have also tried #JOBID#, but got en error, as it was not recognised.

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

SQL & PL/SQL :: Get Count On Group And Total Count For Each Group

Mar 23, 2013

I'm using this code, and it performs fine, but I'm wondering if there is a more elegant way to do it--maybe with "ROLLBACK". Basically (as you can see) I need to get a normal count for each group but also for each group take a percentage of the total count (so all groups pct adds up to 100 (oh yeah, don't test for zero below, but just a test... )

select
c.Event,
c.code,
count(1) as calls,
total.total_count,
count(1) / total.total_count * 100 as pct_of_total
from
table1 c

SQL & PL/SQL :: Joins With COUNT

Nov 16, 2011

I pulled in 1121 SSN's into a table and am using that table as the basis for returning data from other tables...including how many documents a user has in their folder.

My query; however, is only returning 655 rows...it is returning only those rows that have documents in their folders. I want to return ALL rows...WHETHER OR NOT THEY HAVE A DOCUMENT COUNT (count(*)). How can I get all 1,121 rows to return? I would like the output to look like:

SSN LOCATION EMP_STATUS FOL_STATUS COUNT(*)
-- For those folders containing documents:
XXX-XX-XXXX WHATEVER WHATEVER WHATEVER 12

-- For those folders containing 0 documents:
XXX-XX-XXXX WHATEVER WHATEVER WHATEVER NULL

Here is the query in it's current state:

-- Get User/Folder/Doc Count Information
SELECT b.ssn,
b.location,
b.emp_status,
c.fol_status,
COUNT (*)

[Code]....

So again, my problem here is that...not all FOLDERS contain DOCUMENTS...but I still want the folder data lised...I just need it listed with either a zero count (0), or a NULL in the COUNT(*) column.

I'm trying the various joins, but none of them seem to be working.

I've tried the old 8i (+) join as follows:

AND c.fol_id = d.doc_fol_id(+)

I've tried the inner join:

AND c.fol_id(+) = d.doc_fol_id

...and I've tried the 9i method (left outer and full outer) using the following types of notations:

folder c full outer join documend d on c.fol_id = d.doc_fol_id

...so far, no luck. I'm still having only 655 rows returned (the 655 are those folders that HAVE document count > 0. Any folder that has zero documents in the document table just aren't being returned in the query.)

SQL Inline Count

Jun 14, 2007

we're having a few tables which queries about 10.000 articles. As we don't show them all at once we are using pagination and use the rownum to show only a limited number of the results.

Now as these queries are pretty complex we have to optimize them and since we use pagination we have to call our query twice (first we make a count(*) and then we call the small resultset of a few rows). Ofcourse we are looking for a solution to call it only once and still use the pagination. We could load the whole resultset of 10.000 results and let java show only a few but that makes our line between the oracle and webserver pretty heavy. Is there a way to call the total number of results and give back only a small resultset just in one query?
