SQL & PL/SQL :: Duplicated Entries In A Valid Unique Index?
May 26, 2010
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 a table DN_ACTIONS with 9.5 million records. Column DA_OBJECT_NAME is not unique and same object name can have multiple entries. Column DA_ACTION_STATUS can have any values between 1 to 5.
I want to find all the DA_OBJECT_NAME in DN_ACTIONS where all of its entries has DA_ACTION_STATUS=3.
best way as it does a self join on big table of 9.5 million.
(select distinct a.DA_OBJECT_NAME from DN_ACTIONS a where not exists ( select distinct DA_OBJECT_NAME from DN_ACTIONS b where a.DA_ OBJECT_NAME = b.DA_OBJECT_NAME and b.DA_ACTION_STATUS != 3))
I'm trying to add a column in an existing form. I added a text item and defined it as a database item. When I tried to rename the item the message (frm-15500 valid and unique object name must be entered)appears, and therefore not able to exit the property Platte.
Is there a way I can exit the Platte and should I've first add the column to the data block and then rename in my form ?
Using Oracle 11g, below is the table, partitions, unique and non-unique local index:
CREATE TABLE DOCA( DOCA_ID NUMBER NOT NULL , DOCA_BKG_PAX_ID NUMBER NULL , ROW_PURGE_DATE DATE NULL ,)PARTITION BY RANGE(ROW_PURGE_DATE)INTERVAL(NUMTOYMINTERVAL(1, 'MONTH'))( PARTITION P2007 VALUES LESS THAN (TO_DATE('01/01/2008', 'dd/mm/yyyy')), PARTITION P200801 VALUES LESS THAN (TO_DATE('01/02/2008', 'dd/mm/yyyy')),) TABLESPACE T0; ALTER TABLE DOCA ENABLE ROW MOVEMENT;
CREATE UNIQUE INDEX XPKDOCA ON DOCA( DOCA_ID ASC, ROW_PURGE_DATE ASC)LOCALREVERSE TABLESPACE I0; ALTER TABLE DOCA ADD CONSTRAINT XPKDOCA PRIMARY KEY (DOCA_ID); CREATE INDEX XFKDOCA_DOCA_BKG_PAX_ID ON DOCA( DOCA_BKG_PAX_ID ASC)LOCALREVERSETABLESPACE I0;
I would like to know the difference between the performance of the unique and non-unique local indexes?.
I have created a table: INDEX_SIZE_TRACKING with the following attributes
Index Name: name of the index. Type: VARCHAR(255). This is the primary key of the table.
Allocated Space: the memory space (in bytes) allocated to the index. Type: NUMBER
Used Space: the memory space used by the index. Type: NUMBER
Last Update: the time when index details are updated to this table. Type: VARCHAR(255)
I want to write a PL/SQL script to query index statistics data and update tracking entries in the INDEX_SIZE_TRACKING table. If there is no existing entry for the index, create a new one; otherwise, update the existing one. have a PL/SQL statement that can do this in oracle XE?
I have a running application where i have a table with pk defined on it and the pk clumn is inde in asc order by default. Can i alter the index in desc order as i always need to see the data in desc order.
SQL > CREATE UNIQUE INDEX index_debug1 ON debug_table (SLNO);
Index created.
SQL > ALTER INDEX index_debug1 ADD COLUMN MESSAGE; ALTER INDEX index_debug1 ADD COLUMN MESSAGE * ERROR at line 1: ORA-02243: invalid ALTER INDEX or ALTER MATERIALIZED VIEW option
I have a table which sees a lot of use for queries
CREATE TABLE CASE_STAGE ( ID NUMBER(9) NOT NULL, STAGE_ID NUMBER(9) NOT NULL, CASE_PHASE_ID NUMBER(9) NOT NULL, "CURRENT" NUMBER(1) NOT NULL, --and other columns )
ID is a primary key CASE_PHASE_ID is a foreign key
"CURRENT" should only ever have values of 0 or 1. When it has a value of 1 it is unique for that CASE_PHASE_ID
What I have tried that doesn't work is
create unique index case_stage_F_IDX1 on case_stage("CURRENT", case_Phase_id) which gives me ORA-01452: cannot CREATE UNIQUE INDEX; duplicate keys found
What is the correct syntax, something like ("CURRENT"=1,case_phase_id) seems right but fails with an error about a missing bracket. Do I need to use a CASE statement here?
11.2.0.1...How do I create an index on a view or any workaround that my view won't get duplicates?
SQL> create unique index indx01 on db_backup_details_vw(id); create unique index indx01 on db_backup_details_vw(id) * ERROR at line 1: ORA-01702: a view is not appropriate here
I 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?
I want to delete the duplicated record using following methods, it delete the records if all the record are matched according to condition, but if all records are not matched then it display error messages.
SQL> SELECT * FROM XYZ;

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 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!
currently developing a app for MSM in tromsø, that are going to delete the oldest entrys in the database table and then update all the relative Run history entrys in another table.
And i can't get the coding right to truncate the old entrys.Here are the
In oracle 9i ........How to delete duplicate entries in a table ?
if suppose in a table named office, one or more entry(row) is repeated more then twice or minimum twice. I need a query to delete the multiple entries ....
Note: --->No constraints applied on the table. --->No Primary Key --->You cannot create any object....that is no view or a duplicate table can be created
I'm trying to generate count of the number of entries in a table for each day.The problem is the date column is of datatype timestamp and looks like this "2006-12-30 18:42:03.0"
How would I generate a report of number of entries in the table for each date (I'm not intrested in the "time" only the "date" i.e YYYY-MM-DD)?
SELECT COUNT(*) FROM my_table_name WHERE my_date_column LIKE '2006-12-30%' GO
It returns zero rows ( and I kno there are rows in the table) I'm using Oracle 10g.
and I was wondering if there is a quick method of populating it with calendar data so it would look like the following:
Product Year Month A 2008 Jan A 2008 Feb A 2008 Mar A 2008 Apr A 2008 May A 2008 Jun A 2008 Jul A 2008 Aug A 2008 Sep A 2008 Oct A 2008 Nov A 2008 Dec A 2009 Jan A 2009 Feb Etc.
I need to Update Oracle tnsnames.ora file with the some new entries ....i was looking for ora 92, but could not find a proper link to download.now I have oracle 11 g, but i cant find tnsnames.ora file in that...is it because my installation was not proper...
I've created a materialized view log on table with the following statement:
CREATE MATERIALIZED VIEW LOG ON table_a WITH ROWID, SEQUENCE (column_a, column_b, column_c) INCLUDING NEW VALUES;
The insert is done with the following statement:
INSERT /*+ APPEND PARALLEL("table_a") */ INTO "table_a" ("column_a", "column_b", "column_c", "column_d_sum") (select column_a", "column_b", "column_c", "column_d_sum" from table_B)
But the Log is empty when the insert is finished. When I insert rows without the APPEND hint, rows are created in the log table. So, doesn't the log record bulk loads?
Tabular form works fine for first entries, but upon going back to add more records Page 55 has a button that links to the 'Approval' page which is a tabular form (Page 56).A text field at top of this tabular form receives the pass of a varchar2 field from page X which is an identifier (not PK). Tabular form query has condition WHERE ISO_NUMBER = :P56_ISO_NUMBER
When I add records on the first pass to the tabular form and click submit all is fine and dandy.When I get out of the tabular form and go back to it and add additional records I get this error:
Error in mru internal routine: ORA-20001: Error in MRU: row= 1, ORA-20001: ORA-20001: Current version of data in database has changed since user initiated update process. current checksum = "C4B43B9A17A41D287D55DEFE9B035944", item checksum = "607C07E22C9B03E6A45AF44EDC06BB31"., update "SPICE_HUNTER1"."DOC_APPRV_DOC" set "APPRV_DOC_ID" = :b1, "DOC_INFO_ID" = :b2, "ISO_NUMBER" = :b3, "DOC_APPROVER" = :b4, "DOC_APPROVED" = :b5, "DOC_APPROVAL_DT" = :b6, "DOC_COMMENT" = :b7, "APP_USER" = :b8Here's what I've done to try to figure it out:
1. Ran debug and saw it was happening in my MRU; and 2. In the past what I have cleaned out tabular form table data because I've found that when I'm in this testing mode going back and forth with changes gets fouled up, but with a clean slate it still happens. 3. I had Hidden the ID fields, and then remembered this was one of the issues with versions of this error. (I actually logged this one to remember!). So I made them Display as Text (Saves State) and unchecked their boxes.
