SQL & PL/SQL :: To Remove Duplicate Rows From Output
Jun 14, 2011
I have a view and in that view i need to remove duplicate rows from output. For that i need to run select query in where clause of view if select query return true then we need to execute second condition.
my requirement in view like
And..........
And ((select count(*) from table A where conditions)=1 )then name is null
AND
in that code first we need to check first select query condition then we need to apply name is null condition. but i tried to run it but select query not run properly. because tables is used in View.
how can i get distinct records through this coding, when i add select distinct col1, col2, col3 from tablename where RECD_ON between :control. REC_ FROM and :control.REC_TO; in 1st qry after begin, this form not retrive any data from database, then how i get distinct rows through this coding. is there any option in property plattee to get distinct rows.
declare qry varchar2(5000); n number; alert number; Begin [code]....
I have following query: type EMP_REC is record ( id number, name varchar2(20), dept number );
type EMP_TBL IS TABLE OF EMP_REC INDEX BY BINARY_INTIGER; EMP_TABL1 EMP_TBL;
select * BULK COLLECT into EMP_TBL1 FROM emp;
How to remove duplicate records from EMP_TBL1 collection if exists.I don't want to remove duplicate records from main table. But actually want to remove duplicate records from EMP_TBL1 collection if exists.
select am_obj_emp_obj(empno,ename,sal,deptno,service) from (select empno,ename,sal,deptno ,service from emp_vw where 1=1 and rownum < 2000 and service in ('MAN','SACH','SACL','KACL')) WHERE SAL = (SELECT MAX(SAL) FROM EMPS_VW WHERE DEPTNO = deptno or sal is null) union all
[code]...
This query is pulling 12 records of which 6 records are coming from the first query and the same 6 records is coming from the second query after union all Here am_obj_emp_obj is the object type and emp_vw is the view
Now I wanted to remove the duplicate records.When I implement the union operater it is giving me error.
ORA-22950: cannot ORDER objects without MAP or ORDER method.
I want to remove matching dbid's from the rman catalog without compromising te integrity of the catalog. I do however know a single way of removing them and its using the dbid and db_key which in my case are not not unique. The funny thing is they've running normally for a year now.
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).
Currently I have a requirement where I need to create 2 more output rows using each result row.
In my requirement I am populating charges table with types of charges, on each line item of charges, I need to apply 2 types of taxes and populate it along with the charge line item. I will be storing charges in table charges and the 2 taxes to be applied in taxes table respectively. For each row of charges, i need to apply these 2 taxes present in taxes table resulting in 3 rows output.
SSD@ermd> desc person_pos_history Name Null? Type ------------------------------------------------------------------------ -------- ------------------------
PERSON_POSITION_HISTORY_ID NOT NULL NUMBER(10) POSITION_TYPE_ID NOT NULL NUMBER(10) PERSON_ID NOT NULL NUMBER(10) EVENT_ID NOT NULL NUMBER(10) USER_INFO_ID NUMBER(10) TIMESTAMP NOT NULL DATE
We found out that few person_id's are repeating for a particular event (3):
select PERSON_ID, count(*) from person_pos_history group by PERSON_ID, EVENT_ID having event_id=3 and count(*) > 1 order by 2
If we look at the 1st person id "217045", we can see that it is repeating 356 times for event id 3.
SSD@ermd> select POSITION_ASSIGNMENT_HISTORY_ID, POSITION_TYPE_ID, PERSON_ID,EVENT_ID, to_char(timestamp, 'YYYY-MM-DD HH24:MI:SS') 2 from person_pos_history 3 where EVENT_ID=3 4 and person_id=217045 5 order by timestamp;
356 rows selected.It is safe to assume that the person id/event id with the earliest timestamp is the one that was loaded 1st, hence, the one we want to keep and the rest should be deleted.
CREATE TABLE A(EMP_ID NUMBER, EMP_NAME VARCHAR2(100)) CREATE TABLE B(EMP_ID NUMBER, EMP_ATT1 VARCHAR2(10), EMP_ATT2 VARCHAR2(10)) INSERT INTO A VALUES(1, 'ONE'); INSERT INTO A VALUES(2, 'TWO'); INSERT INTO A VALUES(3, 'THREE');
[Code]....
This query returns all the matching row of A and B
SELECT A.EMP_ID, A.EMP_NAME, B.EMP_ATT1, B.EMP_ATT2 FROM A INNER JOIN B ON A.EMP_ID=B.EMP_ID
The output for this shows:
EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2 1 ONE 1ATT1 1ATT2 2 TWO 2ATT1 2ATT2 2 TWO 2ATT1.1 2ATT2.1 3 THREE 3ATT1 3ATT2
The requirement is to avoid duplicate rows even if matched:
EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2 1 ONE 1ATT1 1ATT2 2 TWO 2ATT1 2ATT2 3 THREE 3ATT1 3ATT2
I am trying to find sum for one record for each partition but while taking that timestamp giving me bit trouble, i have tried to reproduce the table and some little data
CREATE TABLE TEST_COUNT (END_TIME DATE ,SUCCESSFUL_ROWS NUMBER ,FAILED_ROWS NUMBER ,TBL_NAME VARCHAR (4) ,PARTITION_NAME VARCHAR (240) )
column sid format 'a5' column serial# format 'a10' column mins_running format 'a15' column sql_text format 'a100' set linesize 200 set pagesize 30
[Code]..
I am running this code, and the output shows multiple lines.
TRIM(S.SID) TRIM(S.SERIAL#) MINS_RUNNING SUBSTR(Q.SQL_TEXT,1,70) ---------------------------------------- ---------------------------------------- --------------- ---------------------------------------------------------------- 700 46592 242.08 Select count(*) as count, case when count(*)>0 then 'FAIL' else 700 46592 242.08 'PASS' end as result from (SELECT cv.code_value FROM code_valu

Is there a way to wrap up the column for SQL_TEXT VARCHAR2(64) so that I can 1 row for the output?
I can get it through this query : select PARTY_ID from XXWFS_CUSTOMER_EXT group by PARTY_ID having count (PARTY_ID) > 1;
Now for the records which i got for each duplicate row i want to update the second row with a specific value.. so that duplicate rows does not exist anymore
Ex: I got party id's 12, 14, 16, 18 two times each
Now as 12 is two times.. i want to update the second row of 12 with some x value same is the case for other values like 14,16, etc
Name _____ Smith Street Smith Street John Street Ed Street Ed Street Ed Street
and need to assign sequence numbers only when the record (Name) changes, e.g. :
Name Seq _____ ____ Smith Street 1 Smith Street 1 John Street 2 Ed Street 3 Ed Street 3 Ed Street 3
I have experimented with row_number partition but then i just get the sequence returning to 1 when the name value changes.
If I grouped the records by Name I would like to have unique, sequential numbers: 1, 2, 3 but where there is the same name I would like the sequence to stop and the number to replicate?
I have one table in which I want to restrict some records from being inserted. I don't want to put any checked constraints. e.g. consider following table
transaction( id number primary key, txn_date timestamp(7), payee varchar2(40), amount number, memo varchar2(40), ref_num number )
I want to write SQL which should not inset duplicate record.
e.g.
I have written one as bellow:
insert into transaction select 1, to_date('2009-12-12','YYYY-MM-DD'), 'Payee1', 12, 'Test', 212 from dual where (select count(*) from transaction where txn_date=to_date('2009-12-12','YYYY-MM-DD') and payee='Payee1' and amount=12)=0;
Can I use exists/not exists, which query will be more appropriate. (Please consider that fields which I am using to filter out the duplicate transactions does not contain primary key.)
Can I write such SQL. Or do i check for duplicate rows one by one and then filter the duplicate records.
