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.
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)
[Code]...
From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

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.
in another form(which is tabular) i want to display bill_id's from detail form.but in detail form . There are same bill_id's more than once.but i want to display those bill_id's which are more than once only once.
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 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..
SELECT DISTINCT B.TIC_ID, B.TIC_ISS_NO,
B.TIC_NUMBEC||CEV_ID,
B.TIC_NUMBEC, B.CEV_ID, B.AOSTED_DATE,
B.COMAANY_CODE, B.CONTCACTOC_NAME,
B.FC_CODE, B.C_NO, B.FC_TYAE,
[code].......
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.

is it possible to remove duplicate values in plsql collections without using multistage operators ?
plsql collections output:
ID NAME

001 A
002 B
003 C
004 D
005 E
005 E
005 E
expected output

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 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).
We are working on a migration project and we need to move 75 million rows from source system to target system.
Total number of columns in source system - 90 cols.
Out of the 90 columns 10 cols are system fields and rest 80 are properties for each record.
We are required to migrate all system cols and some required properties. In total we will migrate around 25 columns[10+15] for each record.
Before actaul migration , we need to do a data cleansing activity and hence we move the data to a staging table.
To create the staging table, we considered the below appraoches.
1. Create the staging table with around 30 coloumns so as to fit the data from source system[map the columns based on datatype]
2.Create the staging table with actual columns[90 columns] and import only the required properties. The rest all columns will remain NULL.
Do the data cleansing and move to target system.
My question here is, if we go with approach 2, We will not mix the data, as there will be a one-to-one mapping. But many columns will not have data and remain NULL. Will it affect the performance since we deal with 75 million rows.
I need to add values of one column values from a table to another table each value as a column. Below i am considering only for 3 values in real time i have more than 50 values
CREATE TABLE TEST_REG ( VAL VARCHAR2(1));
INSERT INTO TEST_REG VALUES ('A');
INSERT INTO TEST_REG VALUES ('B');
INSERT INTO TEST_REG VALUES ('C');
CREATE TABLE TEST_HOLD ( COL1 VARCHAR2(1),COL2 VARCHAR2(1),COL3 VARCHAR2(1)); -- in realtime i have 100 columns
Now i need the output as:
when i
select * from test_hold;
COL1 COL2 COL3
A B C
I want to get the values and put them into html template since i want to configure mime settings. My table's name is rawticket_voip and it has 150.000rows and 20 columns so instead of COL1, COL2 what should i write there? How can i get the spesific row's and column's value and how can integrate loops in this html?

I have a row which contains 6 columns where I want that data to be shown in the form of columns as shown here:
From:
select item1, item2, item3, amt1, amt2, amt3 from item_table where sno=1; <----- returns 1 row as below
ITEM1 ITEM2 ITEM3 AMT1 AMT2 AMT3
---------- ------------ ------------- ----------- ------------ ----------
AAA BBB CCC 10.00 20.00 15.00
Data explanation: item1's (AAA) price is amt1 (10.00), item2's (BBB) price is amt2 (20.00) and item3's (CCC) price is amt3 (15.00). OK.
Now I want that data to convert into columns as shown here:
To:
ITEMS AMT
--------- ---------
AAA 10.00
BBB 20.00
CCC 30.00
I want a SQL to display this data.
I found one query which converts a row into columns, but this does not serve my requirement: [for your reference only]
SQL> select substr( the_string
, decode( level, 1, 1, instr(the_string,',',1,level-1)+1)
, decode( instr(the_string,',',1,level), 0, length(the_string), instr(the_string,',',1,level) - decode( level, 1, 0, instr(the_string,',',1,level-1))-1)
) the_value
from ( select (select item1||','||item2||','|| item3 from item_table where sno=1) ITEMS
from DUAL)
connect by level <= length(the_string)-length(replace(the_string,','))+1

I have a requirement to execute the query only once for all the columns mapped to a particular table. Lets take an example..
table t1 has the following columns mapping.
col1 col2 col3 col4
variable 1 table abc col1_abc ----
variable 2 table abc col2_abc ----
variable 3 table xyz col1_xyz ----
variable 4 table xyz col2_xyz ----
variable 5 table xyz col3_xyz ----
variable 6 table xyz col4_xyz ----
In col4 , we have to update the values of col3 (column) ... it is very easy to update the values by executing the query for each column but my requirement is ... I want to execute the query once for a table ( example select col1_abc,col2_abc from table_abc ... this will return always a single value after adding other conditions in where clause) and why I want to do this? .. because there can be multiple (might be 30 variables values)
from a single table.
I have converted the columns into rows by using listagg function now I have lets a dynamic query ( for the above example).
for i in 1.2
loop
l_query := ' select col1_abc, col2_abc from table_abc';
open c1 for l_query;
end loop;
my problem is : how to hold these values and update the above table?
I've recieved a recent request wherein the requirement is to swap values between columns across multiple tables in a database.Following is a visual sample of what needs to be done.
Before Swaping:
Columns Values
TABLE1.IDENTIFIER MRN123
TABLE1.MEDICARENO CHI1234567
TABLE2.MRN MRN123
TABLE3.MRN MRN123
OTHERTABLE.MRN MRN123
After Swapping:
Columns Values
TABLE1.IDENTIFIER CHI1234567
TABLE1.MEDICARENO MRN123
TABLE2.MRN CHI1234567
TABLE3.MRN CHI1234567
OTHERTABLE.MRN CHI1234567
I am trying a pl/sql block which which take a string and execute it dynamically. Suppose below is string
M_COL := Q'[(P_CODE=> ':DEPTNO',P_CODE_TYPE => 'STATE')]';
Now trying to execute it. using below
M_STR := 'SELECT CHK_DEPT' || M_COL || ' FROM EMP WHERE EMPNO=''7499''';
EXECUTE IMMEDIATE M_STR
INTO M_DATE;
Now what i want is M_STR vairable to executed as
SELECT CHK_DEPT(P_CODE=> DEPTNO,P_CODE_TYPE => 'STATE') FROM EMP WHERE EMPNO='7499'
instead of
SELECT CHK_DEPT(P_CODE=> 'DEPTNO',P_CODE_TYPE => 'STATE') FROM EMP WHERE EMPNO='7499'
other in other way in parameter P_CODE Column value of DEPTNO should be passed.Also note that DEPTNO column in string M_COL is Dynamic.i.e
M_COL := Q'[(P_CODE=> ':DEPTID',P_CODE_TYPE => 'STATE')]'; OR
M_COL := Q'[(P_CODE=> ':EMP_ID',P_CODE_TYPE => 'STATE')]';

My requirement is to concatenate two column values and place them in a new column.I have done it using self join but it limits the purpose,meaning when I have more than 2 values for grouped columns then it won't work.How to make this dynamic,so that for any number of columns grouped,I can concatenate.
SELECT a.co_nm, a.mnfst_nr, a.mnfst_qty,
a.mnfst_nr || ':' || a.mnfst_qty || ';' || b.mnfst_nr || ':'
|| b.mnfst_qty
FROM vw_acao_critical a JOIN vw_acao_critical b
ON a.co_nm = b.co_nm AND a.mnfst_nr = b.mnfst_nr
[code]......
What will be the case when I need to concatenate for more number of values.
like when co_nm has three bahs and manfst_nr and manfst_qty has 3 values for each for bah.and if three are having same_mnfst nr then I should use something dynamic.how to achieve this.
