SQL & PL/SQL :: How To Eliminate Duplicate Values From Table
Nov 24, 2011
I need to delete the duplicate values from plsql table OR move the distinct values in plsql table to other plsql table.
how can i do this ?
DECLARE
TYPE alist IS TABLE OF VARCHAR2(10) INDEX BY BINARY_INTEGER;
p_tbl alist;
BEGIN
p_tbl(1) := 'A1';
p_tbl(2) := 'B2J';
p_tbl(3) := 'A1';
[code]......
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'm trying to eliminate duplicate string for more than 1 occurrences along with its delimiters, but couldn't get it working. Here is what I tried.
SQL> column str format a30
SQL> column replaced format a30
SQL> with x as
2 (select 'a#~#b#~#a#~#d' as str from dual union all
3 select 'a#~#b#~#c#~#a' as str from dual union all
4 select 'b#~#a#~#c#~#a' as str from dual)
select str,
regexp_replace(str, '[^a|#~#a]{2,}','',1,2) replaced
from x; 5 6 7
STR REPLACED
------------------------------ ------------------------------
a#~#b#~#a#~#d a#~#b#~#a#~#d
a#~#b#~#c#~#a a#~#b#~#c#~#a
b#~#a#~#c#~#a b#~#a#~#c#~#a
The output I need is
a#~#b#~#d
a#~#b#~#c
b#~#a#~#c

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.

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 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
)

description VARCHAR2(30));
INSERT ALL
INTO prim_tbl VALUES (1,'aad')
INTO prim_tbl VALUES (1,'aads')
INTO prim_tbl VALUES (2,'bb')

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

Database version: 11.2.0.3.0
I need to remove duplicate values from concatenated long string of state codes(comma separated). Ex: 'VA,VA,PA,PA,CT,NJ,CT,VA'. I tried following query and did not get required out put.
select regexp_replace('VA,VA,PA,PA,CT,NJ,CT,VA,CT,PA,VA,CT','([^,]*)(,1)+($|,)', '13') new_str from dual;
Define Meta-character's format in regular expression to get desired result. Out put required: VA,PA,CT,NJ (with out any duplicates).

My scenario is to insert values into 'out' column by comparing 's' and 'IP' columns of temp table.The exact situation is at first need to go to ip column,take a value and then go to source column and check for the same value of ip which is taken previously.Then after corresponding ip of that source column should be inserted back in previous source column.
The situation is marked clearly in file which i am attaching with '--' comments at respective places.I am also pasting the code which i tried out,unfortunately it is giving error as exact fetch returns more than requested number of rows since there are duplicates in the table.I tried it using nested for loops.Also implemented using rowid,but it didnt work.
fixing the errors or if there is any new logic that can be implemented.
DECLARE
i_e NUMBER(10);
BEGIN
FOR cur_1 IN(SELECT IP from temp where IP IS NOT NULL)
LOOP
FOR cur_2 IN(SELECT IP from temp where s=cur_1.IP)

I have a table like below:

6 other
tableB

The result I need when updating another table with this info is:TableC

021 1 concrete, wood, fiber glass
032
025

521
I do not want :
concrete, concrete, concrete, wood, wood, fiber glass
SO far I am using the following but since I am dealing with hundreds of column that has the same material, when using listagg() from oracle 11.2g, they column width is too wide to fit into the required column.
update eris_data_work e set E.flex37 =
(select
LISTAGG(CM.des, ',') WITHIN GROUP (ORDER BY CM.des) AS casing_material
from CODE_CASING_MATERIAL CM, TBLCASING CA
where CM.code=CA.MATERIAL and CA.well_id=E.owner_oid AND CM.DES IS NOT NULL
GROUP BY CA.well_id)
where E.source='WWIS_ON'
I have even used the regexp_count() to try to eliminate duplicates however I have had no success so far
