SQL & PL/SQL :: Updating And Deleting Of Data

May 21, 2010

I have been using MSaccess to do some updating and deleting of data.I have 2 tables, 1 with data, 1 with the criteria to change, 2 colums (FINDWORD and REPLACEWORD).

The main table has lots of data, and the SQL query im using in access looks like this:

UPDATE TABLE1, tblFindReplaceWords SET CleanList.COLUMN-NAME = Replace([TABLE1].[COLUMN-NAME],[tblFindReplaceWords].[FINDWORD],[tblFindReplaceWords].[REPLACEWORD]);

how would I go about doing the same thing in orcale?

SQL & PL/SQL :: Updating Current Column With Previous Columns?

Dec 22, 2011

I need to update the current column with sum of the previous column values. Following are the creation scripts

DROP TABLE TEST_LOG;
CREATE TABLE TEST_LOG
(

[Code]....

Above query is working fine to retrieve the previous column values.But when we are updating the SUM_PRE_COLS column with those values it's not working fine.

I tried by using the following query

UPDATE TEST_LOG T SET SUM_PRE_COLS =
( SELECT LAG(T2.KEY0, 1, 0) OVER(ORDER BY T2.KEY0) + LAG(T2.KEY1, 1, 0) OVER(ORDER BY T2.KEY0)
FROM TEST_LOG T2 WHERE T2.ROWID= T.ROWID);

PL/SQL :: Code Erases Previous Month Record While Updating Current Month Record

May 16, 2013

Using 11gR2, windows 7 client machine. I need to update the table missing_volume (below), where I need to calculate the estimated_missing column. The calculation of estimated_missing column for current month needs previous month numbers (as commented inside the code below). I want the output like the first table. Notice the records start from January, hence estimated_missing for January can't be calculated, but for the the rest of the months it can be done by simply changing 'yr' and 'mnth' (commented inside the code towards the end).

yr          mnth          location     volume          actual_missing          expected_missing     estimated_missing
---------------------------------------------------------------------------------------------------------------------------------
2013            January          loc1          48037          24               57                         
2013             February     loc1          47960          3660               53                      24
2013             March          loc1          55007          78               57                      28
2013             April          loc1          54345          72               58                  77The code:

UPDATE missing_volume g

[Code]....

The code does calculate correct number for 'estimated_missing' as I run the code for each month, but the problem is while updating the current month it also erases the record for previous month. E.g. as can be seen below, after I updated April the column only has the record for April, previous month record is gone, similarly updating March removed February, etc. I can't understand why it's happening!! Here is the output I get:

yr          mnth          location     volume          actual_missing          expected_missing     estimated_missing
---------------------------------------------------------------------------------------------------------------------------------
2013            January          loc1          48037          24               57                         
2013             February     loc1          47960          3660               53
2013             March          loc1          55007          78               57
2013             April          loc1          54345          72               58                   77

why it's happening (I mean where is the flaw in the code) and how to get the desired output (first table).

SQL & PL/SQL :: Trigger For Deleting

Jun 4, 2010

I have a table which has a trigger defined as such on the Main table.

before INSERT OR UPDATE OF USER_NM,COmpany_ID,UPDATED_BY_USER
OR DELETE ON MAIN TABLE OLD AS OLD NEW AS NEW
FOR EACH ROW

When I insert the 1st row (by user Scott)

MAIN TABLE

USER_NM CompnyID UPDATED_BY_USER
----------------------------------------------------------------
ABC1Scott

In the audit table I have this information:

USER_NM CompnyID UPDATED_BY_USER OPERATION_PERFORMED
----------------------------------------------------------------
ABC 1 ScottInsert

When an ADMIN user (other than Scott deletes the above row)

MAIN TABLE:

USER_NM CompnyID UPDATED_BY_USER
----------------------------------------------------------------row deleted....

In the audit table i have 2nd entry as:

USER_NM CompnyID UPDATED_BY_USER OPERATION_PERFORMED
----------------------------------------------------------------
ABC 1 ScottInsert
ABC 1 ScottDELETE

Here the updated_by_user is Scott and not ADMIN, even though I am doing the following in the trigger.

UPDATED_BY_USER := sys_context('USERENV','OS_USER')

I want to show the user who has deleted the record which should be ADMIN.

Since the user deleting may not be the samae as the one who inserted.Any clue?

Deleting Tables From Productions DB?

Jun 30, 2010

looking at my oracle DB schema I see that there are considerable number of tables that appear to be backup(!!) of other tables and don't ask me the reason why would some one create backup/temp tables in production.

All the tables almost occupy 7GB of space and I would like to get ride of them. Before I get ride of them I would like to see when the table was last accessed for any purpose like any DDL/DML statements and any Select statements performed on the temp/backup tables as well. Is this kind of information readily available in any SYS tables or should I write a trigger to get the details going forward.

PL/SQL :: Deleting Duplicate Records

Dec 20, 2012

I have a table and it's having duplicate records.

for one particular employee, he is having multiple records with the same data in the table

EMPNO    ENAME     JOB     SAL     DOB
-------------------------------------------------------
1               A           X        100     1956
2               B           Y        200     1974
1               A           X        100     1956
3               C           Z        300     1920

[Code]....

like this am having multiple times the duplicates.

I have written the below query to delete the duplicate records. But it is deleting only one record (if we have 5 duplicates it is deleting only 1 ). But I am looking to delete if we have 5 duplicates need to delete 4 duplicates and keep 1 record in the table.

query which am using to delete the duplicates is

DELETE FROM Table1 a 
WHERE ROWID IN (SELECT MAX(ROWID) 
                FROM Table2 b
                WHERE a.ID = b.ID); 

it is deleting only one row but I want to delete 4 records out of 5 and keep one record.

Deleting Huge Records From Table?

Apr 29, 2013

Consider tables A,B,C,D,E,F. all are having 100000++ records Tables B,C,D are dependent on table A (with foreign key constraint). When I am deleting records from all tables, table B,C,D are taking max 30-40 seconds while table A is taking 30-40 mins. All tables are having indexes.

Method I have used:

1. Created Temp table

2. then deleted all records from B,C,D,E,F for all records in temp table for limit of 500.

delete from B where exists (select 1 from temp where b.col1=temp.col1);

3. why it is taking too much time for deleting records in table A.

SQL & PL/SQL :: Script Hangs When Deleting From Table

May 24, 2010

I'm testing a procedure which loads data into my database, and after each test I want to empty some of the tables and reset the sequences. I have this script to do that...

DELETE FROM COM_MERGE;
COMMIT;
DELETE FROM COM_TITLE;
COMMIT;
DELETE FROM COM_ISSUE;
COMMIT;
DELETE FROM COM_PAGE_ELEMENT;
COMMIT;
DELETE FROM COM_ELEMENT;
COMMIT;
DELETE FROM COM_STORY_TITLE;
COMMIT;
BEGIN
COM_RESET_SEQUENCES;
END;

Today I added the call to the sequences procedure to my script, but I have been using the script to delete from tables for a number of days without problem.However today I am finding that when I run the script it works ok the first couple of times, but when I try running it for a third time, it hangs after the second delete (in other words it stops when it gets to the delete from COM_ISSUE). After this happened the first couple of times I stopped the db and restarted it, then the script was ok twice, but again I'm finding that the script hangs. There is no error message, but the script fails to complete.

I didn't know if it was because originally I had one commit at the end of the script, so I added commits after each delete but that didn't solve it.I am using SQL Developer but I have found the same problem when running the script from SQL Plus.This is the definition of the COM_ISSUE table (just in case the table is the source of the problem).There is only one row in COM_ISSUE.

CREATE TABLE "BILL"."COM_ISSUE"
(
"CI_ID" NUMBER NOT NULL ENABLE,
"CI_TITLE" NUMBER NOT NULL ENABLE,
"CI_DATE" NUMBER NOT NULL ENABLE,
"CI_PRICE" NUMBER NOT NULL ENABLE,
"CI_PUBLISHER" NUMBER NOT NULL ENABLE,
CONSTRAINT "COM_ISSUE_PK" PRIMARY KEY ("CI_ID") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS STORAGE(INITIAL 65536

Objects :: Deleting A Row With Object Column

Jul 4, 2012

I have a table, a superclass and several derived classes.

the table definition looks like this:

/*-------------------------------------------------------------------------------------*/
/* table to store ObjectData for the current session/transaction */
/*-------------------------------------------------------------------------------------*/
create table SessionObjectRegistry(
     oid               number,
     transactid          varchar2(200),
     sessionid          number,
     hash               number,

[Code]....

ERROR at line 1:

ORA-00600: internal error code, arguments: [kkbnftn2], [], [], [], [], [], [], [], [], [], [], []The db is
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production

With the Partitioning, OLAP, Data Mining and Real Application Testing optionsThe error occurs on 11.2.0.3.0 - 64bit as well.

As a workaround i'm not deleting the rows, but setting the stored objects to null. At the end of the routine i can truncate the table with the objects since truncating works. I'm not the administrator of the database, therefore i may not change any settings.

Unfortunately i wanted to be able to share Objects between Sessions, which is possible with this workaround (simply don't truncate at the end), but leaves a lot of crap lying around.

SQL & PL/SQL :: Deleting Duplicate Combination Of Records From Table?

How can I delete the duplicate combination of records from the below table.

The condition is if GID = PID and PID = GID then only one combination of these records should be retained. For example Out of 10-20 and 20-10 only one record should be retained.

Expected result after deletion
