SQL & PL/SQL :: Displaying Records That Are Almost Duplicates With Exception On One Column
Apr 11, 2013I have a view that is displaying records that are almost duplicates with the exception on one column.

I have a situation where I need to only display one status per name at a specific time.I would like to return the following:
Distric name id status logtime

DENVER Steve 222 C 11/24/2012 9:00
So I decided to include a rank for the different statuses to identify the highest rank status and eliminate the lowest rank status records I don't want.
Select distric,name,id,status,
case status
when 'A' then 1
when 'B' then 2
when 'C' then 3
else 4
end statusrank,
logtime
from tst;
[code]...
I would like to return the record with the highest statusrank when they duplicates with the exception of the status column.Is there a built in function I can use for this ? The statusrank can be returned in query. My final return would be:
Distric name id status statusrank logtime

SQL & PL/SQL :: Table With A Non-unique Index Consisting Of Three Columns
Sep 13, 2013I have a table with a non-unique index consisting of three columns. The first column is not null while the remaining two are nullable. Queries using this index will chiefly be made in two ways.
1. Column one and two having values. Column three is null.
2. Column one and thre having values. Column two is null.
In both cases I expect range scan will be used since it's non-unique. In the first case the scan will be on values in column one and two. But what happens in case two. Will the range be on colum one, column two(being null) and cxolumn three? Or will it be on just column one since the second column is null? I have done some testing. I can see , using EXPLAN PLAN, that range scan is used in both cases. how the index is used?
Is there any other drawbacks with an index like this?
PL/SQL :: How To Set Primary Key For A Date Column
May 28, 2013i need to set primary key for a column consists of the datatype date.
View 5 Replies View RelatedORA-02270 / No Matching Unique Or Primary Key For Column-list
Jan 14, 2013I'm trying to make a foreign key against a table which has a unique index instead of a primary key.
i get this error:
Error SQL: ORA-02270: no matching unique or primary key for this column-list
02270. 00000 - "no matching unique or primary key for this column-list"
*Cause: A REFERENCES clause in a CREATE/ALTER TABLE statement gives a column-list for which there is no matching unique or primary key constraint in the referenced table.
my question is (i've searched several times with no results) can i create a foreign key with a table wich has no primary key but a unique index ?example:
CREATE TABLE TABLE1(
IDTABLE1 NUMBER(5),
NAME VARCHAR2(30)
);
CREATE TABLE TABLE2(
[code]....
or TABLE1.IDTABLE1 must be a 'Primary Key' instead of unique index ?I know it should be primary, but i need to know if it would work with the index somehow. The reason is i'm migrating a large database and the original structure in mysql uses fk with indexes and no pks in some tables (48 to be precise)
Server Utilities :: ORA-02270 / No Matching Unique Or Primary Key For Column-list
Jul 6, 2010I was cloning a schema user1 as user2 in the same database.
user1 had quota on 2 tablespaces user1_data and user1_index.
I created user with name as user2.
I created tablespace user2_data only and granted user2 unlimited quota on that tablespace only (did not grant him 'resource' role or unlimited tablespace privilege) Now exported user1 schema as follows
exp system/<passowrd> file=/u05/oradata/dump/user1_schema.dmp log=/u05/oradata/dump/user1_schema_exp.log owner=user1 rows=y constraints=y triggers=y indexes=y statistics=none recordlength=65535 compress=no consistent=n grants=y
then imported in in user2 schema as follows
imp system/<password> file=/u05/oradata/dump/user1_schema.dmp log=/u05/oradata/dump/user2_schema_imp.log fromuser=user1 touser=user2 rows=y constraints=y indexes=y statistics=none recordlength=65535 grants=y
during import i encountered following errors for so many constraints
"ALTER TABLE "table2" ADD CONSTRAINT "constraint_name1" FOREIGN KEY ("CTR_ID") REFERENCES "table1" ("CTR_ID") ENABLE NOVALIDATE"
IMP-00003: ORACLE error 2270 encountered
ORA-02270: no matching unique or primary key for this column-list
IMP-00017: following statement failed with ORACLE error 2270:
I found that the it happened as the primary key of table1 was not created for which error was logged in the log file
. . importing table "table1" 19441 rows imported
IMP-00015: following statement failed because the object already exists:
"ALTER TABLE "table1" ADD CONSTRAINT "T1_PK79" PRIMARY KEY ("CTR_"
"ID") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 65536 F"
"REELISTS 1 FREELIST GROUPS 1) TABLESPACE "USER1_INDEX" LOGGING ENABLE "
. . importing table "table5" 0 rows imported
However, I checked that the T1_PK79 does not exist in the user2 schema though it exists in user1 schema Neither the index for priamry key (T1_PK79) existed in user2 schema not the table <table1> existed before this import Then what could be the reason that I am getting an error "IMP-00015: following statement failed because the object already exists"?
I assume tablespace for index would not be an issue here as other indexes got created properly in user2_index tablespace during this import.
I tried this twice, once with user2 schema and then with user3 schema as well (with different tablespace), but result is the same.
There were no users connected to the database during export and no background jobs were modiying any data in schema user1 while export.
All Columns Of A Table Are Part Of Primary Key Column Of That Table?
Feb 22, 2011if a table contains two columns and both are part of the primary key of that table (Kind of obvoius).
should i opt for a index organized tbale in this case ?Or should i opt for another running sequential colum which would serve as a primary key of this table and define the actual two columns of the system as unique keys.
there is a drawback if a most of the tables of a database contain composite primary keys?
SQL & PL/SQL :: Primary And Foreign Key On Same Column And Foreign Key Index
Aug 25, 2010Create table Car
(Car_cd VARCHAR2(5),
Car_Desc VARCHAR2(50)
);
alter table Car
add constraint Car_PK primary key (Car_CD);
INSERT INTO Car (Car_Cd, Car_Desc) VALUES ('CORLA','COROLLA');
Commit;
[code]....
The requirement necessitates a new table to map car to manufacturer. This mapping table may later be expanded to contain other attributes Engine, MPG, etc to hold details specific to a car.But this is in future.
Create Table Car_Mapping_Details
(Car_Cd VARCHAR2(5),
Manufacturer_Cd VARCHAR2(5));
--Primary Key Constraint
ALTER TABLE Car_Mapping_Details
ADD CONSTRAINT Car_Mapping_Details_pk PRIMARY KEY (Car_Cd );
--Not able to create this as Car_cd is already a PK in this table and therefore has Unique Index
ALTER TABLE Car_Mapping_Details ADD CONSTRAINT Car_Mapping_Details_fk1
FOREIGN KEY (Car_Cd)REFERENCES Car (Car_Cd);
[code]....
But in this case the Car_Mapping_Details.Car_cd is itself is a primary key and therefore has Unique index.Although I was able to create foreign key constraint on Car_mapping_details.car_cd column (which is also Primary Key), I was not able to create Foreign Key Index on this column. It gives me Quote:ORA-01408: such column list already indexed.In other words, not creating foreign index for foreign key column lead to table-level lock? Or will the Unique Index in that primary key column be sufficient to avoid table-level lock?
Way To Eliminate Duplicates
Jun 11, 2013I have a table like below:
tableA
aid des
1 concrete
2 wood
3 straw
4 plastic
5 fiber glass
6 other
tableB
bid material
01 1
02 2
03 3
01 2
01 2
02 3
01 5
The result I need when updating another table with this info is:TableC
edw_id bid Requirement
021 1 concrete, wood, fiber glass
032
025
123
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

Flexible Handling Of Duplicates Using A Trigger
Feb 12, 2007I'd like to achieve the following (and YES, I do know that this is not multi-user safe, but that's not the point here):
Before inserting a record, the trigger shall check if there's already a duplicate one. Duplicate means in this case when there is an intersection of the time frame, defined by two numeric timestamps. That's also the cause why I cannot use a simple UNIQUE constraint here (in my opinion).
Okay, that already works (see code below). But now I need colliding records to be written to a temporary table so that those records can be returned and presented to the user for selection.
create or replace
TRIGGER TRIGGER1
BEFORE INSERT ON FLIGHT_TABLE
FOR EACH ROW
BEGIN
FOR fs_entry IN (SELECT * FROM FLIGHT_TABLE)
LOOP

SQL & PL/SQL :: How To Make Return All Records Except Duplicates
Mar 29, 2010I have a table like this basic example:
ID Product Color Time-In
1 Apple Green May
2 Apple Red April
3 Pear Green May
4 Pear Green April
5 Plum Blue June
In SQL I want to return all 4 fields of the records except those records where Product and Color are identical - in that case it should return the latest (by name of month - preferred) or just the first it finds
So I should get these
1 Apple Green May
2 Apple Red April
3 Pear Green May
5 Plum Blue June
If I do a select distinct then I will only get those fields I test on (product and color), not the rest.

Query Return Results That Contain Duplicates - Only First Or Last Required
May 27, 2008I have this query that returns results that contain duplicates(somewhat). I only want either the FIRST or LAST (either one is fine). Here is the query:
select unique PLLA.attribute4, PLA.item_description from po_lines_all PLA, po_line_locations_all PLLA
where PLLA.po_line_id = PLA.po_line_id
and PLLA.attribute4 is not null
So my output is something like this:
RCE12 This is an item for AUL1
RCE13 This is an item for PWEILL
RCE14 This is an item for AUL1
I just want either the RCE12 or RCE14 record and not both since they both have the same description.
Remove Duplicates From Slowly Changing Dimension
Jun 6, 2013I've got a slowly changing dimension table for products with some duplicate attributes -
UNIQUE_ID | DATE_FROM | DATE_TO | PRODUCT_ID | ATTRIBUTE_1 | ATTRIBUTE_2
1 01-JAN-13 02-JAN-13 423 MONKEY 5
2 03-JAN-13 04-JAN-13 423 MONKEY 5
3 05-JAN-13 08-JAN-13 423 MONKEY 4
4 09-JAN-13 10-JAN-13 423 SUPERMONKEY 4
5 01-JAN-13 08-JAN-13 378 BANANA 2
6 09-JAN-13 10-JAN-13 378 BANANA 3
The natural key should be PRODUCT_ID, ATTRIBUTE_1 and ATTRIBUTE_2. The table should therefore be recreated as follows:
UNIQUE_ID | DATE_FROM | DATE_TO | PRODUCT_ID | ATTRIBUTE_1 | ATTRIBUTE_2
1 01-JAN-13 04-JAN-13 423 MONKEY 5
2 05-JAN-13 08-JAN-13 423 MONKEY 4
