We have table with a column REMARKS,where in text somewhere we are storing name also,Now we are planning to update only names with their service number
REMARKS Column Sample row text:
1.It has been created by John
2.John Created this
3.Assistance taken by John for this
Any query which can only replace john in all rows with 1234 .I can update the value if John comes at same position in all rows using SUBSTR() and concat rest of the text.But not getting how to update JOHN in rows at different positions.
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 .

UPDATE event_request SET REQ_EVENT_DATE = TO_CHAR(REQ_EVENT_DATE - INTERVAL '1' HOUR, 'yyyy-mm-dd hh24:mi') WHERE eventID=123
Oracle returns this error:
ERROR at line 4:ORA-01861: literal does not match format string
where line 4 is REQ_EVENT_DATE = TO_CHAR(REQ_EVENT_DATE - INTERVAL '1' HOUR, 'yyyy-mm-dd hh24:mi').The REQ_EVENT_DATE field was originally populated with this stripped down query:
I have a table test with column containing dates, characters and numbers. I have to extract the number part and the three characters before the number . My data looks like :
TEST ID DATA 1 3/12/2007 2 0 3 3/8/2010 ABC 217 4 NONE 5 COLM XYZ 469 6/8/2011 6 LMN 209
Have got basic form on a table and have a textarea which holds Notes added by user.
So Notes database field is updated on Save / Apply changes button being pressed.But would really like any text added / appended to the Notes field to be prefixed by userid and date / timestamp.
Is it possible via dynamic actions or Javascript to have any new text added / typed to be auto prefixed as per above.
Would only want the first key press in the filed to trigger the auto-prefix and if added text was deleted then the auto prefix to be deleted as well ?? If user doesn't press Save / Apply changes obviously want to leave existing Notes as is.
I am on Oracle 11.2.0.3 on Linux and have implemented Oracle Text.I created Oracle Text indexes with default setting. However in an oracle white paper I read that the default setting may not be right. Here is the excerpt from the white paper by Roger Ford:URL....(Part of this white paper below....)Index Memory.
As mentioned above, cached $I entries are flushed to disk each time the indexing memory is exhausted. The default index memory at installation is a mere 12MB, which is very low. Users can specify up to 50MB at index creation time, but this is still pretty low. This would be done by a CREATE INDEX statement something like: CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M'); Allow index memory settings above 50MB, the CTXSYS user must first increase the value of the MAX_INDEX_MEMORY parameter, like this: begin ctx_ adm. set_ parameter('max_index_memory', '500M'); end; The setting for index memory should never be so high as to cause paging, as this will have a serious effect on indexing speed. On smaller dedicated systems, it is sometimes advantageous to temporarily decrease the amount of memory consumed by the Oracle SGA (for example by decreasing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process.
Once the index has been created, the SGA size can be increased again to improve query performance." (End here from the white paper excerpt)My question is:
1) To apply this procedure (ctx_adm.set_parameter) required me to login as CTXSYS user. Is that right? or can it be avoided and be done from the application schema? This user CTXSYS is locked by default and I had to unlock it. Is that ok to do in production?
2) What is the value that I should use for the max_index_memory should it be 500 mb - my SGA is 2 GB in Dev/ QA and 3GB in production. Also in the index creation what is the value I should set for index memory parameter - I had left that at default but how should I change now? Should it be 50MB as shown in example above?
3) The white paper also refer to rebuilding an index at some interval like once in a month: ALTER INDEX DR$index_name$X REBUILD ONLINE; We are on Oracle 11g and the white paper was written in 2003.
I have a requirement in one of my forms screen.I have a text box(large text area) which should display a help text file when i move my cursor on the topics displayed on the screen.know the code and the properties to be changed in the text box to accommodate large external file text.
I'm new to Oracle Text. I want to implement search for the unique ids. Like google search when the user start typing 123 it need to brings anything starting with 123 and has show like entries how google will shows. When I add number 4 to like 1234 then it has bring numbers starting with 1234.
I'm facing some problem even after using INSTR function in Oracle.The problem is I have written the logic in the PL/SQL block which appends all the values fetched in a loop on the basis of whether the string is present or not.
For ex:
The first value fetched from the select query first is ABCDEFG which gets appended to a variable The next value fetched is AB even this has to be appended to the variable since this exactly doesn't match with ABCDEFG. The next value fetched is BCDEF even this has to be appended to the variable since this exactly doesn't match with ABCDEFG. The third Value fetched is ABCDEFG this will not get appended presently according to the logic which is correct.
writing that piece of code to append the value fetched which doesn't exactly match with the existing string
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?
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.
*Action: Rewrite the trigger (or function) so it does not read that table.
CREATE OR REPLACE TRIGGER set_date_end BEFORE INSERT OR UPDATE OF issued ON shares_amount FOR EACH ROW DECLARE BEGIN INSERT INTO shares_amount(date_end) VALUES(SYSDATE); END set_date_end; /
i am reading the columns value from different table but i want to update it with single update statement. such as how to update multiple columns (50 columns) of table with single update statement .. is there any sql statement available i know it how to do with pl/sql.
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.
I have a column "empno" in EMP table and "deptno" in DEPT table . I want to update both the columns with single UPDATE statement. With out a creation of stored procedure or view(updating it through view).
