here is my table...
id name bits
A 1 011011101 00
B 2 011011111 01
C 3 100100010 11
Here, I need to write a query to change 0 to 1 and 1 to 0 for every record value in table of bits column.
for ex: 011011101 00 of id - A must be changed to 100100010 11
similarly, 100100010 11 of id - C must be changed to 011011101 00
Now I need to write a query to update values of bits column in one shot.
Can we use FROM clause in update command?
View 2 Replies View Relatedi have a given pl/sql program that first deletes records out of a table and afterwards inserts new rows. now for example 2 rows out of 10 have a foreign constraint and can not be deleted that easily anymore. so i delete the ones i am able to (with the where not exists clause).
now i want to update the records who have a foreign key constraint and the rest with a regular insert. how would i do this the easiest way. i thought i could use insert with a where clause!!

I use sqlplus in oracle (linux). I have a table and the string cell have long string . Like below :
CODEcolumn A Column B
A BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
.....................................BBBBBBBBBBB
So, I need to edit/update the row A and the value in Column B. But the string in Column B is so long and I only need to edit one character. IF I use update command , I need to type very long string and it is easy to wrong edit .

Assume that we have table Test with a column TestId and Status. This table is having 10,000 records. Now, we need to write a stored procedure that does the following:
1) Select top 10 rows whose "Status = NEW'
2) Update the selected top 10 rows with "Status = PROCESSING"
3) Return those top 10 rows.
Assuming there are hundreds of such requests coming to Oracle database, how can we make sure each request NEVER gets a duplicate record at any given point of time and how to fetch the records that have been updated individual request?

View 3 Replies View Related I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?

This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
The problem I am having is that it is updating all rows even when it is pulling back a null value for b.sak_request. I've tried adding b.sak_request is not null to the select statement like this:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
WHERE b.nam_eds_tracking_id = c.id_dir_track_eds
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.
i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "table %s.%s is mutating, trigger/function may not see it".
*Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.

How to update above values with single update query.
After many tests I can't make work and update of the same table inside the same table.
Trying to avoid Mutating Table Error now I have
ORA-00036: maximum number of recursive SQL levels (50) exceeded
Sample Data :
create table test_compound (USERID VARCHAR2(10),APP VARCHAR2(15),LAST_UPDATED_ON TIMESTAMP);
insert into test_compound values ('user1','1',systimestamp);
insert into test_compound values ('user2','2',systimestamp-4);
insert into test_compound values ('user3','3',systimestamp-6);
CREATE OR REPLACE TRIGGER trigger_test
FOR UPDATE ON test_compound
COMPOUND TRIGGER
TYPE t_tab IS TABLE OF VARCHAR2(50);
l_tab t_tab := t_tab();
[code].......
When I execute :
update test_compound
set last_updated_on=systimestamp
where userid='user1' and app='1';
The trigger should update the first row and all the data from test_compound table where userid='user1'. Maybe the problem is that updating the same table inside the trigger is firing in a recursive way the trigger.
