How to do a query.
I have two tables A and B. In table A there is a field which contains a string of 20 characters; this essentially holds 5 codes of 4 characters each.
Table B is a reference table. It holds the 4 character code and the description.
I am trying to run a select query to bring back the description of the code for the first 2 codes in table A but i am not sure how to bring back the descriptions! The below is what i am trying to achieve.
SELECT
TableA.ID,
SUBSTR(TableA.Code,1,4) Primary_Code,
[Code].....
I have a table DW_ORDER_CHANNEL and I need to know what are the other objects accessing this table. As i need to alter this table so the dependent objects get invalid. how to get the dependent object on this table?
View 2 Replies View RelatedThere are 2 tables : Table A and Table B.Table B has foreign key reference to Table A.There are 2 forms in the application based on table A (form 1) and table B (form 2).
Now when we open form 2, the functionality is such that it acquires a lock on table B for the selected record during the search criteria. Lock is acquired by using "select 1 from table_B where column = :column for update no wait".So when the form 2 is opened by any other user/session and same record is tried to be selected, then an exception is raised to the user that the current record is being edited by some other user and does not allow him to edit that record.
Now imagine if User has opened screen 2 (One record in Table B has been locked). With this lock existing, we open form 1, and click a button which performs a COMMIT_FORM. At this point the form hangs. On checking the locked objects, there is a lock on both table A and table B. When the Form 2 is closed, then the Form 1 which was hanging a while ago starts responding.
When the foreign key relationship is dropped and the above scenario is tried, there is no issue encountered. Form 1 works fine even if form 2 is open.We are not supposed to drop the Foreign key relationship as well.
I have the following table:
CREATE TABLE test_A(member_id NUMBER(2) PRIMARY KEY, MEMBER_name VARCHAR2(20), MEMBER_parent NUMBER(2) DEFAULT NULL);
INSERT ALL
INTO test_A VALUES (1, 'mem1', NULL)
INTO test_A VALUES (2, 'mem2', NULL)
INTO test_A VALUES (3, 'mem3', NULL)
INTO test_A VALUES (4, 'mem4', 1)
INTO test_A VALUES (5, 'mem5', 1)
[code]....
As the actual data is huge, I need to know the best (least expensive) way to select each parent and then all its direct child ordered by member_id the output should look like:
1mem1(null)
4mem41
5mem51
6mem61
2mem2(null)
7mem72
8mem82
10mem102
3mem3(null)
9mem93
11mem113
I have to create a function which count the max id in the provided table.
For example: I have two table customer and book
and
create or replace function Row_Count(tab_nam) return varchar2 is
CONTR_NO varchar2;
begin
select NVL(MAX(t.contract_num), 0) + 1
INTO CONTR_NO
FROM tab_nam t;
return(CONTR_NO);
end Row_Count;
when I call
Function( customer) ;
or
Function( book) ;
It should tell the max number with addition of one.

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?
I have table test1(id,name) and table test2(id,,name)
Now when I update name column of a row on test1 I want the same value to be updated for the same id in test2.

begin
update test2 set name=new.name where test2.id=id
end

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;

View 3 Replies View RelatedMy scenario is I need to insert into History table when a record is been updated into a tabular form(insert the updated record along with the additional columns Action_by,Action_type(Like Update or delete) and Action Date Into History table i.e History table contains all the records as the main table which is been visible in tabular form along with these additional columns ...Action_by,action_type and action_date.

I am trying to update columns of Table A with the columns of Table B. Both these tables have 60,000 rows each. I tried this operation using following 2 queries:
Query 1
Update TableA A
set
(A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3
from TableB
where A.CODE=B.CODE)
Query 2
Update TableA A
set
(A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3

where A.CODE=B.CODE)
where exists
A.code = (select B.code
from TableB B
where A.code=B.code)
When i execute these two above queries, it keeps executing indefinitely.
I need to take a snapshot of a table before insert or update happens to that table.... in oracle 10g. I am reading the MV docs from oracle and below link..
[URL].......
how MV should be written for this and how to schedule it in dbms_jobs for auto refresh?
assuming that t1 is the table where DML operation are goin to happen so before any insert or update, snapshot has to be taken, and I am assuming that to do this it would look something like this?
create materialized view my_view refresh fast as select * from t1;
create materialized view log on my_view;
and then schedule in a dbms_jobs?

I am working on an application that requires very dynamic access to data. Users will build queries through the interface and the queries will be stored in VARCHAR fields for later use. The function that later uses the query has no way of knowing the field names or data types used in the selection query.
This isn't an issue in any program language that I have used before but in this case, we want to do this in a package within Oracle rather than an external application.
how to reference a field by its location or position in the query.
We need to get the list of fields so we know what each field is named and we need to be able to get at its value dynamically as well. If possible, checking the data type would be useful too but that is less important in this case.If we were doing this in say PHP, we could simply reference the query row and use a command like...
foreach($myrow as $field=>$value)
and this would walk through each field in the row giving us the field name and its value.We need to do this same type of thing in our package.
how I can write a query that get a column data point to another column data in a csv file? For example:
Column A Column B
First Name Mike
Last Name Smith

My problem is the following:
At the time when P_delivery_date changes in P_ORDERS I want to transfer P_delivery_date to S_delivery_date in S_ORDERS for corresponding records.
Tables:
purchase orders table P_ORDERS:

Is it possible and what would be the solution using the TRIGGER on table P_ORDERS to update S_delivery_date with P_delivery_date in S_ORDERS?
how to adjust a total (counter) after a record is inserted into a table.
the dilemma i am facing is we are using third party software for our fundraising operations so I have no control over what gets done in the background as users process their daily batches into the system. below is the scenario:
create table paytable(
idnumber number(12),
appealcode varchar2(20),
batchno number(8),
trantype varchar2(3),
transnum number(8),
split_transnum number(8));
[Code]..
IDNUMBER APPEALCODE BATCHNO TRA TRANSNUM SPLIT_TRANSNUM

16084 DVFG1206 20120808 PP 23853576 1133821

1234 DVFG1206 20120808 PP 23853578 1133822
create table appealtable
(appealcode varchar2(20),
total# number(9),
total$ number(13,2));
[Code]...
APPEALCODE TOTAL# TOTAL$
-------------------- ---------- ----------
DVFG1206 100 2500
during batch posting records are inserted into the paytable, on some pledge donations donors will send overpayments when fulfilling a PLEDGE(as is the case with donor 16084) therefore the system will split the payment during the process and will assign a trantype of 'PP' to the exact pledge amount and a 'PPO'(pledge payment overage) towards the balance. additionally as records get inserted into paytable there is counter of those paytable records going into the appealtable for that particular appealcode so in the case above when batchno 20120808 is completed appealtable.total# will show 103 and total$ will show $2532($10,$12,$10,,,I did not include payment$ since that is not the focus of this issue and will not change).
mgt wants the counter into the appealtable to be 2 instead of 3 records since the two records that were split(same split_transnum) should be recorded as one response not two.
I have tried writing an after insert trigger(dreaded mutating table error) and can't seem to figure out how to update the counter to the appealtable after records are inserted into paytable. below is some code I've been working with but it's not working.
CREATE OR REPLACE TRIGGER PPO_Payment
AFTER INSERT ON paytable
FOR EACH ROW
DECLARE
p_cnt NUMBER :=0;

I used to have two tables to store details of PROPERTIES e.g UNIT_COMMERCIAL , UNIT_RESIDENTIAL. I need to combine both of them into one table called UNIT. I moved the data to the new table, but now I am stuck how to update the values of the child table which called MARKETING.

Now, I have two tables:
MARKETING (ID NUMBER PK , OLD_UNIT_ID NUMBER FK ...)
UNIT (NEW_ID NUMBER PK , OLD_UNIT_ID NUMBER ... )
I need to update the value of OLD_UNIT_ID in Marketing table to be equal to NEW_ID in the table of UNIT. As you can see the values of OLD_UNIT_ID in both tables are the same.
I used this statement
update ( SELECT distinct M.UNIT_ID , U.OLD_ID , U.ID FROM MARKETING M INNER JOIN UNIT U ON (M.UNIT_ID = U.OLD_ID)) set unit_id = idBut I got this error:
