1) first record with value 30 and then with value 0.
2) if there are 3 duplicate records ex: ID is 1 and Group KK, then i have to delete both 30 & 0 qty records.
3) If there are more than 3 duplicate records ex: ID is 3 and Group is AA, the i have to delete all the records with qty value either 30 or 0 and.
I have written a query like below.

ORDER BY id, unit)

Sep 29, 2011How can I delete the duplicate combination of records from the below table.
CREATE TABLE test
(
gidNUMBER(10),
pidNUMBER(10)
);
INSERT INTO test VALUES (10,20);
INSERT INTO test VALUES (20,10);
INSERT INTO test VALUES (25,46);
[code]....
The condition is if GID = PID and PID = GID then only one combination of these records should be retained. For example Out of 10-20 and 20-10 only one record should be retained.
Expected result after deletion

Get Count Of Records Grouped By Another Field From Transactions Table
Nov 5, 2009I 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 :: Procedure To Delete Records / Count Number Of Records Has Been Deleted
Feb 21, 2011I have written the following PL/SQL procedure to delete the records and count the number of records has been deleted.
CREATE OR REPLACE PROCEDURE Del_emp IS
del_records NUMBER:=0;
BEGIN
DELETE
FROM candidate c
WHERE empid in
(select c.empid
from employee e,
candidate c
where e.empid = c.empid
and e.emp_stat = 'TERMINATED'
);
[code]....
PL/SQL :: Check For Any Duplicate Values In COUNT() Column
May 13, 2013I'm going to do some testing, and for that I require to retrieve some data based on a single column e.g test_data_col, which -
1. Has 3 or more count(test_data_col) for a given set of group by columns e.g grp_col1, grp_col2, grp_col3
2. Within the set of rows retrieved, that particular column holds some duplicate values. I don't need the duplicates displayed, just know if duplicates exist or not.
This might explain what I'm trying to do -
grp_col1, grp_col2, grp_col3, test_data_col
1, A, xyz, HELLO
1, A, xyz, HELLO
1, A, xyz, BYE
1, A, xyz, GOODBYE
2, C, pqr, WELCOME
2, C, pqr, GOOD MORNING
2, C, pqr, BAD MORNING
So for condition 1, I do something like this -
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3
FROM test_tab
GROUP BY grp_col_1, grp_col2, grp_col3
HAVING COUNT(test_data_col) >= 3;
In this same query, I want to do something that will tell me if the aggregate COUNT(test_data_col) has any duplicate values within it. Again, displaying the duplicates is not important here.
SELECT COUNT(test_data_col) cnt, grp_col_1, grp_col2, grp_col3,
/*some logic*/ dup_val
FROM test_tab
GROUP BY grp_col_1, grp_col2, grp_col3
HAVING COUNT(test_data_col) >= 3;With the proper coding to replace /*some logic*/, I get following values -
cnt, grp_col_1, grp_col2, grp_col3, dup_val
4, 1, A, xyz, Y
3, 2, C, pqr, N
I just gave dup_val column to explain what I'm trying to achieve.. any other way to know the existence of duplicates in the count aggregate will be fine.My Oracle version is Oracle Database 11g Enterprise Edition Release 11.1.0.7.0

select FirstName, LastName, Name, City, count(*) as Num of Duplicate from TABLE

like this am having multiple times the duplicates.
I have written the below query to delete the duplicate records. But it is deleting only one record (if we have 5 duplicates it is deleting only 1 ). But I am looking to delete if we have 5 duplicates need to delete 4 duplicates and keep 1 record in the table.
query which am using to delete the duplicates is
DELETE FROM Table1 a
WHERE ROWID IN (SELECT MAX(ROWID)
FROM Table2 b
WHERE a.ID = b.ID);
it is deleting only one row but I want to delete 4 records out of 5 and keep one record.

SQL & PL/SQL :: Query To Update Duplicate Records?
Sep 20, 2011The requirement is I have a table (TAB1), wherein I have 3 columns, ID, LID and STATUS.
The value in ID column = ID_SEQ.NEXTVAL,and LID will be either 0 or 1 and the possible values for STATUS are 'ED','CP', NULL. The ID column is not suppose to have duplicate values, but there is no check on the table for the same.
Someone has updated the existing data and ID column is containing duplicate values. Wherever LID = 0 and STATUS = NULL and if only if ID is duplicated then the ID_SEQ.NEXTVAL has to be assigned to ID field, so that there are no more duplicate values.
CREATE TABLE tab1 (id NUMBER , lid NUMBER, status VARCHAR2(10));
Existing Data
------------------
INSERT INTO tab1 VALUES (1,0, 'ED');
INSERT INTO tab1 VALUES (1,0, 'CP');
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
[code]....
get the result using a single update statement.
