How to find the duplicate values in two columns.
Suppose we have two columns A and B and the data looks like this
A B
--- ---
1 One
2 Two
1 One
2 Two
3 Three
I need to write a query in such a way that i should find out the duplicate values which are repeating.
Yesterday (05/08/2010) i have mistakenly inserted duplicate values in the tables, every value is inserted 2 times in a table.
so upto my knowledge the data were correct upto 30/Jul/2010. hence i need to recover the data from this 30th Jul date.
I have two tables
Table1
Id1 Name1
1 Jack
2 Jack
3 John
Table2
ID2 Name2
NULL Jack
NULL John
I would be assigning ID2 from ID1 based on name match.As Jack has 2 ids when I use the statement
UPDATE TABLE2
set id2 = (select distinct ID1 from table1 where table1.name1=table2.name2);
I get an error message as select statement would return more than one row and the update statement fails completely. with the sql statement to update the ID2 as error when we have duplicate records and continue with the update for other records.
like
table
ID2 Name2
ERROR Jack
i have master-detail form.in master my bill_id gets generated when new form is open and i copy the same bill_id in detail(tabular)for each item.all the items which i enter in detail form get save the same bill_id which got generated.

The p_tb1 table contains all the above values including duplicates. Now I need only distinct values to be copied in another plsql table of same type.
I have below query.. When i run this query i need to get two rows.. But i am getting two more duplicate rows.. I want to restrict these two rows..
How can i do this.. Here the problem is when i join B query then only i am getting duplicate rows..

I am trying write a script that will return all values (based on the minimum tarif) from the Germany table for any duplicate values. Duplicate values are any values with the same UFI, ZC,limitid,depot. The German table also contains the fields tarif, city, supplier, etc.
Below is the script I have previously used to sort out duplicates. I have tried 50 different ways get it to return just lines for the minimum tariff but haven't been successful.
select *
from Germany t
where (ufi,zc,limitid,depot) in (
select ufi,zc,limitid,depot from (
select ufi,zc,limitid,depot, count(*) n
from Germany t
group by ufi,zc,limitid,depot)
where n<>1
)
Table contains duplicate data . Have to move data to another table. Criteria: check for duplicate values if duplicate exist move all duplicates except one to the history table. While moving to other table see if the record being moved already exists.

I have a table like this
table:
id name plan code
1 sam normal 5
1 sam normal 6
1 sam special 5
1 sam Special 6
I need to delete data in such a way that one entry with normal and one entry with special plan should remain and should be with different code. Does not matter whether normal stays with 5 or 6 code.
I tried with rowid but it deletes either both normal or both special or returns same code for normal and special.
CREATE TABLE prim_tbl
(id NUMBER,--- id is not primary key here
description VARCHAR2(30));
INSERT ALL
INTO prim_tbl VALUES (1,'aad')
INTO prim_tbl VALUES (1,'aads')
INTO prim_tbl VALUES (2,'bb')
INTO prim_tbl VALUES (2,'cc')
INTO prim_tbl VALUES (2,'dd')
SELECT * FROM dual;
I want to select the ids only one time, i.e my output will have only two rows: one row with id as 1 and other row with id 2 whatever be the description.
desired output sample:
Quote:1, aad
2, bb
I used:
select distinct(id),description from prim_tbl;
but it did not give the required result.How can I get it??
I'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
Are some posibilities to exclude duplicate values do not using sql aggregate functions in main select statement? Priview SQL statement
SELECT * FROM
(
select id,hin_id,name,code,valid_date_from,valid_date_to
from diaries
)
[Code]....
In this case i got duplicate of entry TT2 id 50513 In main select statement cant use agregate functions are even posible to exclude this value from result modifying only the QLRST WHERE clause (TRUNC need to be here)
how to select 1st record from duplicate vales in a table.
If we created one table with out primary key column In form in search block have uwi value and top_depth value when i enter uwi and top_depth value then when i click search button then it will display all values in master block.
but here duplicate values r there.
SQL> select rownum,uwi,top_depth,base_depth,test_start_date from well_pre_header;
ROWNUM UWI TOP_DEPTH BASE_DEPTH TEST_STAR
---------- ---------------- ---------- ---------- ---------
1 100 453.05 458.08 09-SEP-10
2 100 200 288 23-AUG-00
3 1001 200 289 25-AUG-01
4 1001 200 201 24-MAY-87
if uwi = 1001 and top_depth=200 and i will click search button it should be display 3 record & when i click next button then it will show 4th record.
I'm exploring converting our use of pls_integer to simple_integer. My concern is that simple_integer cannot be null. It seems safe to use for count(*), since count(*) cannot return null. But I am not sure about its use in collection methods like i := collection.count or for loops like for i in 1..collection.count
View 5 Replies View RelatedI have a driver table from which I need to update another table while, at the same time, record the fact that I have processed each record on the driver table.
The driver table will contain around 3.5 million records, therefore I intended to handle this using some bulk collections, with a LIMIT option so that I don't hit any memory problems.
I would also prefer to commit in batches, or at least handle exceptions using the SAVE EXCEPTION clause. The problem is I seem to be running into an error when trying to make the update to the driver table (the commented out code). With this in, I get the error:
ORA-01410: invalid ROWID
ORA-06512: at "CUST_MAIL_UPDATE", line 217
ORA-06512: at line 38
Can the CURRENT OF not work with the FORALL? What is my best approach here? If I use a FOR LOOP I lose my SAVE EXCEPTIONS exception handling.
The Procedure is as follows:
-- declare some object structures to hold the retrieved data
TYPE driver_rec IS RECORD (
account_no ext_driver.account_no%TYPE,
update_action ext_driver.update_action%TYPE,
customers_rowid ext_driver.customers_rowid%TYPE);
TYPE driver_recs_tt IS TABLE OF driver_rec;
-- cursor to get the records from the driver table

I was trying to create types inside package like:
-create or replace package pack1 is
type udtable is table of integer index by binary_integer;
end;
-create or replace package BODY pack1 is
type udtable is table of integer index by binary_integer;
end;
Although this is not exact query what i have doubt in my mind. is it possible to create object types/collections inside/with packages?
We can save Associative array in data base, if not why?.
