I have a requirement to delete duplicate records. For example,if the below query retrieves count of duplicate records along with the column values.
select col2,col3,col4,col5,col6,col7,count(*) from table group by col2,col3,col4,col5,col6,col7 having count(*) > 1;
I would like to retain only one record with max(col1) which is a surrogate key and other records should be deleted.How to retain one record in a duplicate record set based on max of certain column.
the following case is successfully done with mssql databases.
Case:
Table UserGroup Columns id, name, handshake
When the handshake is set to 'd', this record should be deleted. I know it is bad behaviour by design.
What have I done so far:
- created an after update trigger (mutual error) Caused by trying a delete action in the update action, not possible.
- created a view in combination of instead of update trigger.
This causes also mutual error, or if ignored (PRAGMA AUTONOMOUS_TRANSACTION), an deadlock.
Code so far:
create or replace procedure Delete_UserGroup_sp(p_groupId in USER_GROUP.HMIUSERGROUPID%TYPE, p_handshake in USER_GROUP.HANDSHAKE%TYPE) is begin if p_handshake = 'd' then delete USER_GROUP WHERE HMIUSERGROUPID = p_groupId; commit; end if; end;
create or replace view USERGROUP_V as select * from USER_GROUP
create or replace trigger USER_GROUP_T1 instead of update on USERGROUP_V for each row declare PRAGMA AUTONOMOUS_TRANSACTION; begin Delete_UserGroup_sp(:new.HMIUSERGROUPID, :new.HANDSHAKE); end;
when i tried to delete the record by clicking the delete button which has the trigger code as
delete from emp where employee_id=:e_id; commit;
it wasn't. and showed the message as ---FRM-40508: ORACLE ERROR: Unable to INSERT record.
if i change the EMP ID item property "database item" to "NO"..then i can able to delete the record..but, now i am unable to insert the record form the same form...
I have written this below code. The logic behind the code is, Delete the duplicate record from a table, and delete those record from other 7 table based on the SL_NUMBER.
But Problem is After delete the duplicate record When I have use Below statement
RETURNING SL_NUMBER BULK COLLECT INTO rec_sl_number;
This statement unable to return approx 40 Lakhs SL_NUMBER
DECLARE rec_sl_number dbms_sql.number_table; BEGIN
I am using 10g and want to let an user to delete a single record from a multirow form via delete button. This button is supposed to do the same, what the "delete record" button on the default menu does. (I want a custom menu, so I can't use that button)
My delete button ist assigned to a control-block and the when-button-pressed-Trigger of that button looks like this: ------------- DECLARE TEMP VARCHAR(30); BEGIN -- Record chosen? IF :<BLOCK>.ID IS NOT NULL THEN
[Code]...
The problem is, that the alert asks the user about the previously chosen record correctly, but if the user clicks BUTTON1 the Form says: No changes to save (FRM-40401).
we have certain users have DBA role assigned. of course they can delete records from sys.aud$.
we are trying to make this go away. we found that in DBA role, there is a role called DELETE_CATALOG_ROLE controls this. if we revoke this role from DBA role, user no longer able to delete records from sys.aud$ but the problem is as a powerful user who has DBA role, they can always grant this back to DBA role, or grant delete from sys.aud$ table directly to themself.
can we create a second role which just like DBA role, but with less privileges?
Created three tables and group by 3 tables column name. want to delete duplicate record without first table(test). Delete the duplicate record in test1 and test2 except test.
SELECT a as Name,b as M_Name, c as L_Name, count(*) FROM ( SELECT first_name as a, middle_name as b, last_name as c FROM test UNION ALL SELECT first_name as a, middle_name as b, last_name as c FROM test1 UNION ALL SELECT first_name as a, middle_name as b, last_name as c FROM test2 ) as countGROUP BY a,b,cHAVING count(*) > 1
My form consist two datablock cust_mstr,cust_dtls, each customer code consists two or three contact details records, when i delete the single detail record instead of deleting single record it deletes all the details records from cust_detail table.

i m using oracle 10g forms. in one form i m using post keyword when i use this function then records saved in temporary database but i want to remove one record from this form but it is allrady saved through post.
i have one table ot_ins_item where user will enter the details of item, grade,item qty , later on user will go and update the same table the details of different grades received for the same item in different columns with qty breakup in 3 different fields it_qty_01 , it_qty_02,it_qty_03 respectively with different grades , what i need is i want is whenever he updates this table with different grades based on data entered in 3 different fields , a procedure or trigger should delete the initial record saved and insert three different rows based on newly updated values , it may be 3 or it may be 2 sometime depending upon input values that many records should be inserted same time controlling the qty's entered in breakup not exceeding the main qty.
INSERT INTO OT_INS_ITEM VALUES (1,s_it_no.NEXTVAL,'A','ITEM1',NULL,NULL,NULL,NULL,NULL,NULL); INSERT INTO OT_INS_ITEM VALUES (1,s_it_no.NEXTVAL,'B','1TEM2',NULL,NULL,NULL,NULL,NULL,NULL); INSERT INTO OT_INS_ITEM VALUES (1,s_it_no.nextval,'C','ITEM3',NULL,NULL,NULL,NULL,NULL,NULL); SELECT * FROM OT_INS_ITEM; [code]....
I totally realize that but here is what im trying to accomplish. I have a table with one column that repeats.the table looks like this.
create table testCheck (check_num varchar2(20), amount number(17,2), invh_Code varchar2(20)) and it has data like so INSERT INTO "TESTCHECK" (CHECK_NUM, AMOUNT, INVH_CODE) VALUES ('001', '50', '1123') INSERT INTO "TESTCHECK" (CHECK_NUM, AMOUNT, INVH_CODE) VALUES ('001', '50', '1123') INSERT INTO "TESTCHECK" (CHECK_NUM, AMOUNT, INVH_CODE) VALUES ('002', '100', '1234'
I would like to write a query that would give me the distinct check_num's but put an asterisk on the items that are actually duplicated.so in other words expected result in this case would look like this.
I've been able to get as far as getting the unique values but what i cant do is figure out for the life of me how to put the asterisk in there.here is my query.
with Checkquery as ( SELECT count(*) over (partition by CHECK_NUM order by CHECK_NUM ROWS UNBOUNDED PRECEDING ) thiscount, CHECK_NUM, AMOUNT, INVH_CODE FROM TESTCHECK group by check_num, AMOUNT, INVH_CODE) select check_num, amount,invh_Code from Checkquery where thiscount ='1';
I simply want to identify the dups put an asterisk on the record and then only select one of the records.
I'm having problem with my database, which contains more than 1 rows with a same value on a field that has uniqueness contraint.
Here is the log from sqlplus. When I select on RI field, it shows 2 rows. But when I select on SCNUM field, it shows only 1 row. This SCNUM has an unique index on it.
And it is still in VALID state
SQL> set autotrace on SQL> select ri, scnum from scratch1_p where ri in (536964983, 536955574); select ri from scratch1_p where scnum='444393975'; RI SCNUM ---------- ---------- 536955574 444393975
I have now created my tables and now I want to populate them with my data but I get errors below is my full sql command. From last time I learned that one foreign key can be implemented in one table and cannot be duplicated to work around this I changed my foreign key as you can see to "fkone" . but why am I getting errors when trying to add information I mean I have not gotten errors in the first two tables so what am I "doing wrong/ not understanding"
Re: Report Columns duplicated when region is copied.
When I copy a region which I have created via master-detail form, the report columns are duplicated. I'm actually copying the whole page but I have had other cases where I just copying the desired region and the columns were duplicated there as well. And, of course, there is no way that I know to delete columns from the form. But I doubt because -- in at least some cases I've tried -- the columns seems to be "linked" in that a change to one copy of the column was duplicated in the other when changes were applied.
In the example (below), there are three regions on the page and the problem occurs in region 2. (I think I will likely delete the first region.) It's been agonizing trying to get the report of region 2 and the tabular formish edits of region 3 on the same page. I made this in Oracle 11.2 in our APEX 4.1 and imported it to 4.2. You can see it here:
WS apex_examples_01 demo demo Appl. 991204
Page 57 is the original page created in 4.1 and imported Page 58 is the page copied from 57 under 4.1 and imported Page 59 is the page copied from 57 under 4.2 (Same result as in 4.1.)
If you want to try the page, select DSD01 from the DSD LOV, click "Query Process" and then click the edit icon. Ignore the region 1 errors -- I'll probably delete this region. The data is region 3 is for Run Date 12-May-13.
Is there some setting that allows this region to be copied without duplicating columns?
P.S. I think I know why it happens: APEX hates me!
I have to write a procedure that accepts schema name, table name and column value as parameters....I knew that i need to use metadata to do that deleting manually.
I am loading data file using SQL Loader in TOAD 10.5.1.3 in Oracle 10g using the control file below and loading data into 2 tables post1.thead and post1.tdetl. THEAD contains item level transaction and TDETL is detail level when a transaction has a discount or promo attached to for that item. When the
LOAD DATA APPEND INTO TABLE post1.thead WHEN (1:5) = 'THEAD' TRAILING NULLCOLS (file_type POSITION(1:5)CHAR,
[code]....
A particular THEAD value may have 0, 1 or many TDETL corresponding values.below is a sample data file. When the position 21 in the TTAIL has a value of 1 or 2, then we know that there is a promo or discount applicable to the ITEM (THEAD).
What I want to acheive is to accurately reflect a TDETL to its corresponding THEAD, as both THEAD and TDETL are loaded into separate tables. How can we have the 2 records correlated?
I have a table which contains the multiple records for single ID No. Now i have to select single record which contains the latest date. here is the structure Name

now i have to select below 2 rows how can write select qurie for this?
I have a fairly standard Purchase Order form which contains pre-loaded data (been uploaded from an XML file).When the Purchase Order is processed, the form updates a Price History table only if the Price on the PO_Details changes.The code for updating the price history table is contained in a PRE_UPDATE trigger on the PO_Details Data Block.
No other data changes on the PO_Details table.I now want to change this so that the Price History table is updated even if the price does not change i.e I want to create a history record for each record on the PO_Details irrespective of whether it was updated or not.
Is there an alternative trigger that I can move my code to (ie move it from PRE_UPDATE) to some other trigger that is fired for each PO_Details record even if there is no change.
