Can we use select statement in case statment for an update?
Example
UPDATE x SET field = CASE WHEN
(SELECT field1
FROM Y
WHERE field3 = x.field3
IS NOT NULL
THEN 'B'
ELSE 'C'
where cny# = 112160
I am trying to use the below query
update t_emp set TTL_FLG =
CASE
WHEN EXISTS
(SELECT 1 from Schema1.T_STG_LW_EMP E
WHERE E.Employee = Schema2.T_emp.EMPLOYEE_NUMBER
AND E.JB_CODE like '%TP%' or E.JB_CODE like '%DGD%' or E.JB_CODE like '%PDD%'
or E.JB_CODE like '%YND%'
)
THEN 'Y'
ELSE 'N'
END;
I have the following tables:
create table lookups (code varchar2(20), amount number);
insert into lookups values ('Rent' , 500);
insert into lookups values ('Breakpoint' , 10);
create table products (id number, cost number, year varchar2(4));
insert into products values (1, 1000, '2011');
insert into products values (1, 2000, '2011');
insert into products values (2, 100, '2011');
insert into products values (3, 50, '2011');
commit;
I want to write a query which lists the IDs and the sum(cost), and a Y/N indicator which is set to 'Y' IF sum(cost) > ( (lookups.rent value) * (100 - lookups.breakpoint value))/100
I have written this query:
SELECT id,
sum(cost)cost,
year,
CASE
WHEN cost >
((SELECT amount
[code]....... ORDER BY id;
This returns
ID COST YEAR YN
--------- ---------- ---- -
1 1000 2011 Y
1 2000 2011 Y
2 100 2011 N
3 50 2011 N
The YN is correct, but it needs to sum the amounts. So there should only be one row for id1 = 3000.e.g.
ID COST YEAR YN
--------- ---------- ---- -
1 3000 2011 Y
2 100 2011 N
3 50 2011 N
I am not sure how to do this. Or is there a better way of doing this than using CASE.

I would like to know, if there is a solution under 10g for something like this
select case when "C" = 1
then
(select 1,2,3,4,5 from dual)
else
(select 6,7,8,9,0 from dual)
end
from dual,
(select 1 "C" from dual)
What I really need is the full result of (select 1,2,3,4,5 from dual) or (select 6,7,8,9,0 from dual) if a condition as a result of a different sql-statement is true or false. It doesn't matter if the solution uses "case when" or anything else.
i tried the following update on one table:
update siebel.s_contact
set marital_stat_cd =
case
when (marital_stat_cd = 'Casado') then 'Married'
when (marital_stat_cd = 'Solteiro') then 'Single'
when (marital_stat_cd = 'Divorciado') then 'Divorced'
end
As you can see i forgot the else, so my update is wrong.
I thought i could rollback the update issuing the rollback statement, but when i have issue the rollback, the i query the table to confirm that the update was rollbacked and for my suprise the update is commited.
I didn�t issue the commit statement after the update and i confirmed that the auto-commit feature to worksheets is disabled, so i don�t understand whit the update was commited.
We have and Upper and a Lower function.Is there any function or way in which I can issue a select while ignoring the case(like IgNoReCaSe) in a where clause? I don't want to use like
select * from emp where upper(job)= upper('dba');
or
select * from emp where lower(job)= lower('dba');
I just want to know if there is any way in which I could do it without using upper and lower.
I want to count the batch records using BATCH_ID with CASE statement ,for that i am using below query but its not working ,
SELECT COUNT(*) FROM <TABLENAME> WHERE VNBATCH_ID=CASE WHEN #SDC <10 AND #PERIOD >=10 THEN
0||#SDC||#PERIOD||#BATCH_ID
WHEN #SDC <10 AND #PERIOD <10 THEN
0||#SDC||0||#PERIOD||#BATCH_ID
WHEN #SDC >=10 AND #PERIOD <10 THEN
#SDC||0||#PERIOD||#BATCH_ID
ELSE
#SDC||#PERIOD||#BATCH_ID
END

I wrote a simple procedure to copy the create timestamp and create user name to update timestamp and update user name of the same record. (See code below)
This works fine for a hard-coded table and primary key column. However, I cannot figure out how to get this to work with dynamic sql.
All my other procs, which don't use SELECT UPDATE FOR work fine with dynamic sql.
Proc that works:
CODECREATE OR REPLACE PROCEDURE proc_set_upd_columns
IS
CURSOR c1 IS
SELECT *
FROM mytable
FOR UPDATE
ORDER BY mycolumn;
c1rec c1%ROWTYPE;
[code].........

We have this statement in our database:
select <primary key> from <table> where <primary key> = 1 for update.
Issuing the above statement in 9i, results in a ROW-S (SS) shared type of lock on the table. However, in an identical database in 10g, it results in ROW-X (SX)type of lock. we see all that by qeurying view DBA_DML_LOCKS. Why the different behavior in 10g? Or is it an ORA.INI setting that causes this behavior?
In addition, in 10g the select for update blocks other users trying to access different rows in the table thru oracle forms 6i application. We see this because DBA_DML_LOCKS reports "Blocking" in column "BLOCKING_OTHERS" for the specific row.
how can i insert and update to a table in oracle database 10g through a select statement. not using merge.

I'm looking for a solution to select the first row that is not currently locked in a table and insert a record to another table that reference that first row. this is my scenario:

my goal is finding the first free ticket ( not sold ) in the ticket table and insert buyer information of that ticket in customer_ticket table. at last I will mark that ticket as a sold one in ticket table with update.
Problem is that the first transaction locks the the first row in ticket table and the second transaction running the same query goes to wait untill the first transaction commit or rollback. However when first transaction finish successfully, second transaction select duplicate id from ticket table that was selected by the first transaction!
I tried to solve problem with "skip locked" and "nowait" options with select for update, but they didn't work.

View 2 Replies View RelatedI'm having a strange case of ORA-01002 Fetch out of sequence when I perform a process in the application.
Application logs, trace files (produced with dbms_monitor),
A system trigger to capture the error - all proved that the culprit is a single SQL,
*Not a PL/SQL block* That caused the issue:
Select COL1, COL2, COL3, COL4, rowid
FROM TAB1
WHERE COL1 = :1
AND COL2 = :2
AND COL3 = :3
ORDER BY COL1 ASC, COL2 ASC, COL4 ASC
FOR UPDATE NOWAIT;

Also, My trigger looks like this:

I've read some about this error and everywhere it says that it has to do with fetching from an invalid cursor,And all the examples I've observed are of PL/SQL block - never seen any example/explanation of how it happens in a SQL query.
if the OCI maybe is somehow doing things different than the logs/triggers show?
My code executes a Select For Update before updating a table. In some cases the network is disconnected and it causes the lock to hang. Then, I must kill the session in order to realese this lock.
I want to do it automatically. I would like to create a job that kills session that has a lock due to Select For Update that is not alive.
i have two tables test1 and test2. i want to update the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE
v_mydept1 TEST1.DEPT_CD%TYPE;
v_mydept2 TEST2.DEPT_CD%TYPE;
CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR;
[code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF"
I am not sure what is the exact problem when we want to update multiple columns of different tables.
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?

Im trying to make a query to get the grades of students, I already figured out how to get the average from the exams. Now I would like to make like a select case or if statements to get the actual grade.
Something like this:

average > 79 then grade = 'B'
average > 69 then grade = 'C'
average > 59 then grade = 'D'
else grade = 'F'

This is my query:

SET a.sak_request = (
SELECT b.sak_request

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
