Rerieve Duplicate Rows from a SELECT statement

Hi, I want to see all the duplicate rows from my SELECT statement. Looks like Oracle by default suppresses the duplicate rows. Here is my SQL statement.
I like to see all the 5 rows. Please help.
select a.partid, a.pdesc
from product a
where a.partid in ('10-30000-4',
'10-30000-4',
'10-30000-4',
'10-30000-4',
'10-30000-5')

Looks like Oracle by default suppresses the duplicate rowsSure no, if you have duplicate rows, Oracle will show you the dup rows.
Please, paste your data and the query result.
And this is no because you'll put multiple time the same condition that Oracle will show you multiple time the same row (in case of non-duplicate).

Removing duplicate rows from SELECT

Hi, I was wondering if there was any way to remove duplicate rows from a select statement.
My table looks like this:
CREATE TABLE CUS_ID_TO_PC_ID (
CUSTOMER_ID VARCHAR2 (10) NOT NULL,
PC_ID VARCHAR2 (25) NOT NULL,
PASSWORD VARCHAR2 (25) NOT NULL,
REG_DATE DATE,
PRODUCT_DESC VARCHAR2 (25),
EXPIRE_DATE DATE,
SERIAL_NBR VARCHAR2 (12),
LDAP_USER VARCHAR2 (200),
COMMENTS VARCHAR2 (2000),
PC_ID_5_4 VARCHAR2 (25),
PC_ID_6_0 VARCHAR2 (25),
PASSWORD_5_4 VARCHAR2 (25),
PASSWORD_6_0 VARCHAR2 (25),
PC_ID_6_1 VARCHAR2 (25),
PASSWORD_6_1 VARCHAR2 (25),
OPERATING_SYSTEM VARCHAR2 (20),
STATUS VARCHAR2 (1)
Basically, I want to retrieve all columns from the table but remove all duplicate variations of
the pc_id/serial_nbr combinations.
For example, given this data:
PC_ID SERIAL_NBR CUSTOMER_NO
1234567 AAA C345
1234567 AAA C567
3333333 BBB C456
only the 1st and 3rd rows would be returned.
Any ideas?

Try something like this:
select * from your_table yt
where rowid in (select max(rowid)
from your_tabel yt2
where yt2.pc_id = yt.pc_id
and yt2.serial_nbr = yt.serial_nbr);

Count the number of rows resulting from a select statement

Hi,
Is there any way of counting the number of rows resulting from a select statement. i.e I have a select distinct statement and I then want to perform an IF statement on the number of rows resulting from the select statement.
Any help appreciated
Thanks
Gary

Declare
var1 number;
Begin
select count(distinct column_name) into
var1 from table_name;
If var1 > x Then
End IF;
End;
Hope I understood the problem correctly

How to update duplicate row from table

Hi,
how to update duplicate row from table?
First to find duplicate row then update duplicate row with no to that duplicate row in oracle.
can you give me suggestion on it?
Thanks in advance.
your early response is appreciated...

In order to find a duplicate row, see:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1224636375004
(or search this forum, your question has been asked before)
In order to update it, just create and use an Oracle sequence, have it start and increment at a value that doesn't exist in your table.
If that doesn't get you going, post some CREATE TABLE + INSERT INTO statements, and the results you want from them, in other words: a complete testcase.

First attempt to remove duplicate rows from a table...

I have seen many people asking for a way to remove duplicate rows from data. I made up a fairly simple script. It adds a column to the table with the cell selected in it, and adds the concatenation of the data to the left into that new column. then it reads that into a list, and walks through that list to find any that are listed twice. Any that are it marks for DELETE.
It then walks through to find each one marked for delete and removes them (you must go from bottom to top to do this, otherwise your row markings for delete don't match up to the original rows anymore). Last is to delete the column we added.
tell application "Numbers"
activate
tell document 1
-- DETERMINE THE CURRENT SHEET
set currentsheetindex to 0
repeat with i from 1 to the count of sheets
tell sheet i
set x to the count of (tables whose selection range is not missing value)
end tell
if x is not 0 then
set the currentsheetindex to i
exit repeat
end if
end repeat
if the currentsheetindex is 0 then error "No sheet has a selected table."
-- GET THE TABLE WITH CELLS
tell sheet currentsheetindex
set the current_table to the first table whose selection range is not missing value
end tell
end tell
log current_table
tell current_table
set list1 to {}
add column after column (count of columns)
set z to (count of columns)
repeat with j from 1 to (count of rows)
set m to ""
repeat with i from 1 to (z - 1)
set m to m & value of (cell i of row j)
end repeat
set value of cell z of row j to m
end repeat
set MyRange to value of every cell of column z
repeat with i from 1 to (count of items of MyRange)
set n to item i of MyRange
if n is in list1 then
set end of list1 to "Delete"
else
set end of list1 to n
end if
end repeat
repeat with i from (count of items of list1) to 1 by -1
set n to item i of list1
if n = "Delete" then remove row i
end repeat
remove column z
end tell
end tell
Let me know how it works for y'all, it worked good on my machine, but I know localization is causing errors sometimes when I post things.

Hi again!
Try that:
SELECT rowid, fst_name, last_name, email_addr, work_ph_num, row_id, last_upd, bu_id
FROM ADDT_RPT_REQ A
WHERE rowid > (SELECT MIN(rowid)
               FROM ADDT_RPT_REQ B

                 AND B.last_upd = A.last_upd
                 AND B.bu_id = A.bu_id);This query should show you all duplicate rows. Use the rowid and DELETE to get rid of these rows.
DELETE FROM addt_rpt_req A
WHERE rowid IN (SELECT rowid
                FROM   (SELECT rowid, row_number() OVER (PARTITION BY fst_name, last_name, email_addr, work_ph_num, row_id, last_upd, bu_id
                                                         ORDER BY row_id) dup
                        FROM addt_rpt_req)
                        WHERE dup > 1);Yours sincerely

How to pass an array to a function from a SELECT statement

Hi all. I have a problem with passing an array to a function directly from a SELECT statement.
Here is what I want. If I have a function
function AAA(arrayVar <ArrayType>) return number;
I want to be able to call this function this way
select AAA((2,3,4))
from dual
or this way
select AAA((10,12))
from dual
In other words I want to be able to pass an arbitrary number of numbers to the function. And I want this to work in a SELECT statement.
Does anyone have any ideas how to implement this? What <ArrayType> should I use?(I've read about VARRAY, nested tables in the Oracle documentation but as far as I've understood these array types are meant to be used within PL/SQL blocks).
I found only this http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:208012348074 through Google but it didn't help me.
Thank you in advance.

> What <ArrayType> should I use?
SQL data types - as 3360 showed above. You cannot use PL/SQL structures and user types in the SQL Engine.
You can however use all SQL structures and types in PL/SQL.
Arrays in SQL is created as collection type - basic o-o. The collection type (or class) serve as a container for instantiated objects or scalar type.

Querying many tables at once from a select statement for specific values

Hi all,
I'm very new to PL/SQL and have a daunting task ahead of me. I'm pretty sure our database normalization scheme is all out of whack, which I dont have the experience to fix yet, but this is the task ahead of me without getting to change or fix our structure:
in the universe has 1000+ tables.
need--> Some of those tables have fields that contain a value that has to be changed.
The only thing I have to go on is the column name will contain 'EMP'... but there is no specific naming convention for the column names.
When I search on:
select * from all_tab_columns where column_name like UPPER('%EMP%')
It returns 750 rows. (So 750 rows = 750 columns in 500 different tables (some tables have 2 or more columns in it))
tables names are random (table1, table2, etc).
columns names are random with EMP in it (column1,column2,etc).
I have 75 possible field values that I need to check each of those 750 columns for.
Maybe this is too messy, but I'm looking at subqueries, joins, arrays, cursors, etc, anything to minimize the amount of work I have to do.
I think this is too much to do a join with, but that seems to be what all the documentation is pointing me to.
can you point me to a simple example of what i could
write?
the logic i see it would be
run the select statement to grab the column names that meet EMP.
one at a time, search each column in the corresponding table for the 75 values.
return the results of rows for each column/table that meet one of the 75 unique values.
I'll have to also update each of the 75 values to (used to be values 1, 2, 3 ... to new values X1, X2, X3, etc.)
Any help at all would be very helpful,
aspiring pl/sql programmer but having a rough time of it

I think you're looking to do something like the following pseudocode:
BEGIN
    FOR tblrec IN (SELECT table_name, column_name
                     FROM all_tab_columns
                    WHERE column_name LIKE '%EMP%')
    LOOP
        FOR rec IN (SELECT ROWID
                      FROM tblrec.table_name
                     WHERE REGEXP_LIKE(tblrec.column_name, '(expr1|expr2|...)')
        LOOP
            DBMS_OUTPUT.PUT_LINE(
                'Found expression on ROWID ' || rec.rowid
                || ' in column ' || tblrec.column_name
                || ' on table ' || tblrec.table_name);

Eliminate duplicate rows from the report 6i output

Hi All,
I have generated a report output with the group by and summary options.
For Ex: report has num and amount columns
I had to sum the amount group by num
NUM AMOUNT
1 100
1 50
2 10
2 100
After group by and summary functions the report is generating the output as follows...
NUM AMOUNT
1 150
1 150
2 110
2 110
I want to eliminate the duplicate rows and want the output as follows...
NUM AMOUNT
1 150
2 110
I tried all the ways to implement distinct, but not able to.
I donot want to implement distinct on the query but want to perform at the report level.
Please help me in this ASAP.
Thanks,
Vijay

It would be helpful if you post your query, should by something like
SELECT NUM, SUM(AMOUNT)
FROM TABLE
GROUP BY NUM
ORDER BY 1this would not create duplicates with your given example data.

How to processing the results from the select statement in SQL query?

Hi
This might be too simple, but my knowledge of the SQL is very limited...
I have table where I do have details from calls (Lync QoE).
I can take all calls from the table, but I would like to count the concurrent calls on the table. This is how I got it work on the Excel to work (but I would like to do that on the SQL statement to get it more dynamic use):
Table have these line and this is what I get out from the Select):

The information I would like to get, is what is the maximum amount of the concurrent calls per day.
On the excel I basically count line by line how many concurrent calls each line have had, and then pickup the highest one. On above example the calls 5DEF, FDE2 and FDE2 have been active at the same time which gives 3 for the first day.
The table is ordered by the start. So let say the code is on the third line (FDE2). I need to count calls from before which end time is after the start time (of FDE2), but also I need to count calls after (FDE2) which are started before the current
call has ended.
