I have data some thing like this.
NO NAME LOC SAL
------------------------------------------------------------------
1 A HYD 100
2 B BGL 200
1 A HYD 200
1 A HYD 150
I want to delete duplicate records (group by no,name,loc) but only max(qty) record should be retained. So I need output like this.

I am trying to delete duplicates from table without using rowid.
here is data:-

insert into test values(100,'rocky');
insert into test values(100,'rocky');
[Code]....
I know i am perfoming dml on view. IT wont allow me to perform DML on view which contain columns with expression. IS there any way to delete duplicates without using rowid?
These are the tables I'm working with:
SQL> desc custinfo;
Name Null? Type
----------------------------------------- -------- ----------------------------
CUSTID VARCHAR2(4)
CUSTNAME VARCHAR2(18)
CUSTADR VARCHAR2(12)
CUSTCITY VARCHAR2(10)
CUSTSTATE CHAR(2)
CUSTZIP VARCHAR2(5)
CAPACITY NUMBER(3)
HOUSECODE VARCHAR2(2)

I don't understand why the custid is the same for each customer, and why it's selecting every customer and not just those with more than 150 gallons ordered.
For this one use the oil tables that you set up and use a subquery. Select the minimum average fall use from the house table. Then show all customers whose number of gallons delivered times two is greater than the minimum.
How can I delete a record by writing code in when_button_pressed trigger.
View 8 Replies View RelatedI am writing a query and I am trying to multiply some of the columns with *1.50 and 0.75.
The columns I am trying to multiply are coke_rebate.volumecsd and coke_rebate.volumencb. I am getting an error in oracle sql command from web "ORA-00937: not a single-group group function"
Here is the code I am writing:

can we delete multiples table through the single query?
suppose we have 2 table first one is emp and second is client
i want delete all data from emp and client through the single line query
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.
I have an Oracle Form 6i. There are two blocks. One is a database block called CUSTOMER and the other is a non-database block called CONTROL.
In the PRE-INSERT trigger of the database block, values from the non-database table block are passed to the database table block. When I pass values I use the :BLOCK_NAME.field_name eg. :CUSTOMER.scale_code := :CONTROL.scale.
In this form the values passed to the database block from the non-database block in the PRE-INSERT trigger do not use the block name e.g. :-
:warehouse := :global.default_warehouse;
:capturer :=captured
:scale_code := scale;
:date_captured := sysdate;
insert into dd_audit(cus_id,cap_date) values(:CONTROL.cus_id,SYSDATE);
This application used to work fine for months, last week when writing the values in the PRE-INSERT trigger, just the warehouse field had a value. The remaining fields after the warehouse did not pass any values, although it was verified that values would have been present in the non-database block. The date_captured field should have at least had the system date. The last insert into dd_audit was successful.
I have done numerous tests on our test database and could not replicate the problem. Would passing the values from the non-database block to the database block without the :BLOCK_name preceding the field name cause this problem.
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 .
I have got 2 users as user1 and user2.I have used the following statements from user 'user1':
create role GENEVAOBJECTS;
grant select, insert, update, delete on PRODUCT to GENEVAOBJECTS;
grant GENEVAOBJECTS to user2;
In the above statements, product is a table. Now, I could able to access this table from user 'user2'. But however if I write a procedure in user2 schema accessing the table product, then the procedure is not getting compiled.
create or replace procedure test_prc as
v_test number(9);
begin
select product_id into v_test
from PRODUCT where rownum=1;
[code]...
why I cannot access that table from procedure?
