I want to remove duplicates from a column MAIN_TABLE based on TLEVEL Column:
create table UNIQ_TEMP
( TLEVEL NUMBER(10,0),
TABLE_NAME VARCHAR2(30),
MAIN_TABLE VARCHAR2(30)
);
[code]....
My Requirement is:
MAIN_TABLE= MARKETING_OPTIN
EXISTS IN MAX(TLEVEL)
REMOVE DUPLICATE MARKETING_OPTIN FROM OTHER LEVELS
This should apply to all the values in column MAIN_TABLE
remove duplicates from my collection(table type).Or an alternate solution for my issue is get clean data into my collection which i am not able to get to either.
Object creation
create table testingtype_table(ordernumber number,org_id number , company_name varchar2(10))
insert into testingtype_table values (1124,2424,'cbaaa');
insert into testingtype_table values (1124,2424,'cbaaa');
create or replace type testingtype_obj as object (ordernumber number,org_id number , company_name varchar2(10));
create or replace type testingtype_tab as table of testingtype_obj;
Code Block
declare
l_testingtype_tab testingtype_tab := testingtype_tab();
begin
select distinct testingtype_obj(ordernumber
,org_id
,company_name)
bulk collect into l_testingtype_tab
from testingtype_table;
end;
If only i can get a way to bulk collect only distinct values into the table type that will just do great but when i try the above (with distinct highlighted in red) it throws an error
ORA-22950: cannot ORDER objects without MAP or ORDER method
Removing duplicates from a string that contains years and "-".
Example: 1988-1997-2000-2013-1998-1965-1997-1899

I have a query like
SELECT country_name,
substr(SYS_CONNECT_BY_PATH(product_name,','),2) as PRODUCT_NAME,
substr(SYS_CONNECT_BY_PATH(SPEED_VALUE,','),2) as SPEED_VALUE,
substr(SYS_CONNECT_BY_PATH(i.SUPPLIERNAME_ACCESSPROTYPE,','),2) as SUPPLIERNAME_ACCESSPROTYPE
FROM (SELECT b.country_name,b.product_name,b.speed_value,(supplier_name|| supplier_product || access_product_type)as
[code].......
In the result , I am getting repeated values for product_name and speed value,something like 'ALL Products,All Products,All Products'in the product_name column and '128Kbps,128Kbps'in Speed_vale.i am not able to remove the repeated values here.
I'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
3 09-JAN-13 10-JAN-13 423 SUPERMONKEY 4

I have created a table and i have a column consisting of 1000 records (but where i have duplicates). And now i want to create a primary key for the column.

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

I have an XMLType column that is validated via some XMLSchema. Now I want to remove this restriction and make it just a generic XMLType column. I tried bunch of alter table commands but I couldn't figure out the magic combination. Is this possible?
Here is the actual problem. Unfortunately, we ended up both local and global schemas using the same URL. We have customers out there with both schemas (early customers) or only global schema (new customers). Most of the tables were created before the global schema was added. So, they are referencing the local schema. Now we want to evolve our schema, and I am trying to write a sql script to clean-up this mess. if only global schema exists then (these are late customers)
- do nothingelse if both global and local schema exist then (these are early customers)
- If any table or table.column has dependency on local schema (I can find this out from user_dependencies) I am going to mark those tables/columns as no schema validated. i.e. remove all references to local schema
- delete and purge the local schema
- modify those tables/columns and make them point to the global schema end if
- evolve the schema (only global one is left)
Is there a way to modify a column definition and move its reference from local schema to global schema where both schemas have the same URL? Of course the main constraint is that we do not want to loose customer data. By the way, both local and global schemas are identical in terms of xsd.
is it possible to change XMLSchema/Element settings of an XMLType column from X to Y, X to null, or null to X?
I have a table like below:

6 other
tableB
bid material
01 1
02 2
03 3
01 2

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

021 1 concrete, wood, fiber glass
032
025
123

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 =

I have a table1:
userid, name, town.
Now i want to do a self join like:
select a.name, b.name, a.town
from table1 a
inner join table1 b
on a.town = b.town
where a.first_name <> b.first_name AND
a.last_name <> b.last_name
i added the where clause to limit duplicates i would get but i still get duplicates eg. A B london, B A london etc.
I have to load 50 Million records in a table. I also need to ensure that no duplicate records enter. Business demand is that It may send 2 Million records today, 1 Million records tomorrow, 3 million records on the next day and so on...
I have loaded 6 Million records into the table, but onwards speed of loading records (with duplicate check) is decreasing.
I have need, where I need to pick-up the one of the records out of 2, which have all the fields same but one key column? how should I do it?

I tried with MAX and DENSE_RANK but its not getting me the first row.
I ran an Inner Join but it returned many, many duplicates. One Answer from a different thread:Because you may be having improper Join condition what has a One to many or a Many to many relationship between the tables. We do not have the data, and hence cannot comment over it. What do I look for to identify an improper join?

I'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.

I 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.

I 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.

In MS Windows, if I copy a file and paste it into the same folder, I get a copy with the text 'Copy of' in front of the file name. If I paste it again, I get another copy with a different version number.
E.g.
sqlnet.log
Copy of sqlnet.log
Copy (1) of sqlnet.log
Copy (2) of sqlnet.log
I was wondering if I could copy existing rows into a table and do the same thing?
So, for example if I had this table:
create table tst_srch (srch_is varchar(100), user_name varchar(100), srch_name varchar(100));
insert into tst_srch values (1,'USER1','SRCHA');
insert into tst_srch values (2,'USER1','SRCHB');
insert into tst_srch values (3,'USER1','SRCHC');
insert into tst_srch values (4,'USER1','SRCHD');
insert into tst_srch values (5,'USER2','SRCHC');
insert into tst_srch values (6,'USER2','SRCHD');
insert into tst_srch values (7,'USER2','SRCHD_1');
Could I write a procedure like copy_searches('USER1','USER2') that would copy all USER1's searches to USER2 - including renaming any duplicates.
So it would create these new rows:
8,USER2,SRCHA
9,USER2,SRCHB
10,USER2,SRCHC_1
11,USER2,SRCHD_2
I've looked at various insert statements, merge and match statements and exception handling in procedures .
When I am printing a report in Delimited report format using the default delimiter "Tab", the heading lables is getting printed for all rows( which is fine ) and extra rows of heading labels is getting printed.
Ex:
If I have a heading labels Deptno, Dname and Loc and related data which I print in delimited format, the output will be as follows:
Deptno Dname Loc 10 Accounting NewYork
Deptno Dname Loc 20 Research Dallas
Deptno Dname Loc 30 Sales Chicago
Deptno Dname Loc 40 Operations Boston
Deptno Dname Loc Deptno Dname Loc
Other report formats are working fine.
The same report in different application server environment is working fine.
I am trying the new Oracle 12c and its feature to create columns with the keyword IDENTITY. I create a table CREATE TABLE xt (a NUMBER GENERATED by default AS IDENTITY PRIMARY KEY, b VARCHAR2(10));
And populate it, sometimes specifying the value for a and sometimes relying on the system to generate the value:
INSERT INTO xt (b) values ('a');INSERT INTO xt (b, a) values ('b', default);INSERT INTO xt (b, a) values ('c', 3);INSERT INTO xt (b) values ('d');INSERT INTO xt (b) values ('e');
The problem is that the fourth INSERT fails because the system tries to use the value 3 which is already taken. The fifth statement gets the value 4.
And the table now contains: A B - -1 a 2 b 3 c 4 e Is there something I am missing? I understood that by specifying BY DEFAULT, I would be allowed to sometimes specify values on my own without them interfering with the generated values. I now that the same thing works correctly in MySQL (where I would get five rows from 1 to 5 with the same INSERT statements) /nikos
