Select from tabA & tabB then insert into tabC (these tables ok for form?)
hi everyone,
i have a question for any of you who have a few mins to spare
i have a bunch of tables that i will eventually create a bunch of corrisponding forms for... now i want one of the forms to allow the end user to search for records from two tables,,, select some or all of the rows and then use them in either a delete or update statement....
my table set up is shown below:
SQL> desc BOOK_OUT_INFO
Name Null? Type
BOOK_OUT_ID NUMBER(10)
BOOK_CN VARCHAR2(9)
BOOK_CN_NUM NUMBER(3)
BOOK_ISBN VARCHAR2(9)
BOOK_TITLE VARCHAR2(100)
BOOK_AUTHOR_NAME VARCHAR2(30)
BOOK_STATUS VARCHAR2(4)
EMPLOYEE_ID NUMBER(5)
EMPLOYEE_NAME VARCHAR2(30)
EMPLOYEE_ADDRESS VARCHAR2(100)
EMPLOYEE_PHONE_NUMBER NUMBER(7)
EMPLOYEE_DEPT VARCHAR2(15)
EMPLOYEE_SID NUMBER(5)
SQL> desc BOOK_IN_INFO
Name Null? Type
BOOK_CN VARCHAR2(9)
BOOK_CN_NUM NUMBER(3)
BOOK_ISBN VARCHAR2(9)
BOOK_TITLE VARCHAR2(100)
BOOK_AUTHOR_NAME VARCHAR2(30)
BOOK_STATUS VARCHAR2(4)
SQL> desc SEARCH_INFO
Name Null? Type
BOOK_ISBN NUMBER(9)
BOOK_TITLE VARCHbefAR2(100)
BOOK_AUTHOR_NAME VARCHAR2(30)
ok so now.... i need to allow the user to search both BOOK_IN_INFO and BOOK_OUT_INFO, by BOOK_ISBN then select the records they require for use later and have them inserted into SEARCH_INFO....
before i start making the forms is there anything i need to change in the tables?
thanks all
MUCH APPRECIATED
RMMO
I'll give you a hint on how you could solve it.
Let's take BOOK_OUT_INFO table and try to insert some records from this table to SEARCH_INFO table.
Create a button in BOOK_OUT_INFO block, lets call the block BLOCK1. The button would appear for all rows. Write this code in W-B-P trigger of the button.
INSERT INTO TABLE SEARCH_INFO (BOOK_ISBN,BOOK_TITLE,BOOK_AUTHOR_NAME) VALUES (:BLOCK1.BOOK_ISBN, :BLOCK1.BOOK_TITLE, :BLOCK1.AUTHOR_NAME);
COMMIT;
MESSAGE('1 row inserted');MESSAGE('1 row inserted');

Query is taking too much time for inserting into a temp table and for spooling
Hi,
I am working on a query optimization project where I have found a query which takes hell lot of time to execute.
Temp table is defined as follows:
DECLARE @CastSummary TABLE (CastID INT, SalesOrderID INT, ProductionOrderID INT, Actual FLOAT,
ProductionOrderNo NVARCHAR(50), SalesOrderNo NVARCHAR(50), Customer NVARCHAR(MAX), Targets FLOAT)
SELECT
C.CastID,
SO.SalesOrderID,
PO.ProductionOrderID,
F.CalculatedWeight,
PO.ProductionOrderNo,
SO.SalesOrderNo,
SC.Name,
SO.OrderQty
FROM
CastCast C
JOIN Sales.Production PO ON PO.ProductionOrderID = C.ProductionOrderID
join Sales.ProductionDetail d on d.ProductionOrderID = PO.ProductionOrderID
LEFT JOIN Sales.SalesOrder SO ON d.SalesOrderID = SO.SalesOrderID
LEFT JOIN FinishedGoods.Equipment F ON F.CastID = C.CastID
JOIN Sales.Customer SC ON SC.CustomerID = SO.CustomerID
WHERE
(C.CreatedDate >= @StartDate AND C.CreatedDate < @EndDate)
It takes almost 33% for Table Insert when I insert the data in a temp table and then 67% for Spooling. I had removed 2 LEFT joins and made it as JOIN from the above query and then tried. Query execution became bit fast. But still needs improvement.
How I can improve further. Will it be good enough if I create Indexes on the columns for the temp table and try.or what If I use derived tables?? Please suggest.
-PepHow I can improve further. Will it be good enough if I create Indexes on the columns for the temp table and try.or what If I use derived tables??
I suggest you start with index tuning. Specifically, make sure columns specified in the WHERE and JOIN columns are properly indexed (ideally clustered or covering, and unique when possible). Changing outer joins to inner joins is appropriate
if you don't need outer joins in the first place.

Field != then Insert Into Other Table
Hi,
I cannot figure out how to create a trigger that will insert data based on if a old.field != new.field. If the field was changed in
one table tbl_test then insert that record into the other table tbl_test_history. This is a little different since I want to insert a record if a update
took place. The update will still take place in tbl_test but I want a insert to take place in tbl_test_history.
CREATE OR REPLACE TRIGGER AU_INSERT_TEST_HISTORY
AFTER UPDATE
ON TBL_TEST FOR EACH ROW
WHEN (
OLD.Orange != NEW.Orange
OR OLD.Apple != NEW.Apple
BEGIN
INSERT INTO TBL_TEST_HISTORY
(ORANGE,
APPLE
BANANA,
GRAPE
select ORANGE,
APPLE
BANANA,
GRAPE
FROM TBL_TEST, TBL_TEST_HISTORY
WHERE TBL_TEST.PK_TEST_ID = TBL_TEST_HISTORY.PK_TEST_ID;
END AU_INSERT_TEST_HISTORY;
/I will have a separate trigger that will insert records from tbl_test to tbl_test_history. This trigger compiles with no errors but when I
create a record in tbl_test I receive an error. I am not sure if the syntax is correct, can anyone help me with this?My bad. I put the colon : into the when clause. They weren't there in your code. Usually I use an if condition, which is a little different.
I added some NVL logic to to consider comparison of NULL values too.
CREATE OR REPLACE TRIGGER AU_INSERT_TEST_HISTORY
AFTER UPDATE ON TBL_TEST
FOR EACH ROW
BEGIN
if nvl(:old.ORANGE,'xxx') != nvl(:new.ORANGE,'yyy')
OR nvl(:old.APPLE,'xxx') != nvl(:new.APPLE,'yyy')
then
INSERT INTO TBL_TEST_HISTORY
(ORANGE, APPLE, BANANA, GRAPE)
values (:new.ORANGE,
:new.APPLE,
:new.BANANA,
:new.GRAPE);
end if;
END AU_INSERT_TEST_HISTORY;
/ You can additionally consider to make this trigger an AFTER INSERT OR UPDATE trigger.
Then you would also put the inserted values from the start into your history table.

My Internal HD became corrupt and it would not boot up so I installed My osx onto a new HD via usb and then inserted into my macbook pro but it wont boot up. It will only boot up if i connect via usb how can i boot it as an internal HD?

Sorry genius.....but if the Recovery disk shows up that means the disk cable isn't bad. Could be he did have a screwed up HDD and when he put the NEW HDD in (after putting the OS on it via USB) the computer didn't reconize it and therefore didn't boot the OS. Just maybe right genius? Don't rush to criticize someone's recommendations until you realize other possibilities. (I did say "if it does")

Currently, I can copy ONE tab's url and nothing else (not its name). Or I can bookmark all tabs that are open. However, I'd like to have the ability to select multiple tabs and then copy ALL of the the URLs AND their titles/or copy ALL of the URLs+titles+HTML links? This can be done with the Multiple Tab Handler add on; when I download the add on, I get a message saying that using the add on will disable Firefox's tab features. I prefer to use Firefox features rather than download and use an add on. Is there a way to do this without an add on?
Hi LRagsdale517,
You should definitely be able to upload multiple files by Shift-clicking or Ctrl-clicking the files you want to upload. Just to make sure you don't have an old version of the service cached, please clear the browser cache and then log in to https://cloud.acrobat.com/files. After clicking the File Upload icon in the upper-right corner, you should be able so select multiple files for upload.
Please let us know how it goes.

I cannot copy a selection from an Excel 2003 spreadsheet into a Mozilla
Gmail document. When I do so, I lose the format. This just started happening in the past week. I’ve already tried repairing Excel with the original disk and that didn’t fix the problem. I have been doing this for years and all of a sudden it stopped working.
I tried the same process in Chrome and the formatting was lost there as well. It was working before. How do I fix this?Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

Hi, extract data from xml file and insert into another exiting xml file
i am searching code to extract data from xml file and insert into another exiting xml file by a java program. I understood it is easy to extract data from a xml file, and how ever without creating another xml file. We want to insert the extracted data into another exiting xml file. Suggestions?
1st xml file which has two lines(text1.xml)
<?xml version="1.0" encoding="iso-8859-1"?>

These two lines has to be inserted in the existing another xml(text 2.xml) file(at line 3 and 4)

RandomAccessFile? If you know where you want to insert it.Are you sure about this? If using this, the receiving file would have to have bytes inserted that exactly match the number of bytes replaced. I'm thinking that you'll likely have to stream through the second XML with a SAX parser and copy information (or insert new information) as you stream with an XML writer of some sort. -

If the files are large, you probably want to use a StAX or SAX. -

ThanksIts bit urgent
NO - it is NOT urgent. Not to us.
If you have an urgent problem you need to hire a consultant.
I have a performance issue in the below code,
Maybe you do and maybe you don't. How are we to really know? You haven't posted ANYTHING indicating that a performance issue exists. Please read the FAQ for how to post a tuning request and the info you need to provide. First and foremost you have to post SOMETHING that actually shows that a performance issue exists. Troubleshooting requires FACTS not just a subjective opinion.
where i am trying to insert the data from table_stg into target_tab and in parent_tab tables and then to child tables via cursor with bulk collect .the target_tab and parent_tab are huge tables and have a row wise trigger enabled on it .the trigger is mandatory . This timetaken for this block to execute is 5000 seconds.Now my requirement is to reduce it to 5 to 10 mins.
Personally I think 5000 seconds (about 1 hr 20 minutes) is very fast for processing 800 trillion rows of data into parent and child tables. Why do you think that is slow?
Your code has several major flaws that need to be corrected before you can even determine what, if anything, needs to be tuned.
This code has the EXIT statement at the beginning of the loop instead of at the end
FETCH stg_cursor BULK COLLECT INTO v_rt_all_cols LIMIT limit_in;
vstep_no := '4';
vtable_nm := 'after fetch';
--EXIT WHEN v_rt_all_cols.COUNT = 0;
EXIT WHEN stg_cursor%NOTFOUND;
The correct place for the %NOTFOUND test when using BULK COLLECT is at the END of the loop; that is, the last statement in the loop.
You can use a COUNT test at the start of the loop but ironically you have commented it out and have now done it wrong. Either move the NOTFOUND test to the end of the loop or remove it and uncomment the COUNT test.
WHEN OTHERS THEN
ROLLBACK;
That basically says you don't even care what problem occurs or whether the problem is for a single record of your 10,000 in the collection. You pretty much just throw away any stack trace and substitute your own message.
Your code also has NO exception handling for any of the individual steps or blocks of code.
The code you posted also begs the question of why you are using NAME=VALUE pairs for child data rows? Why aren't you using a standard relational table for this data?
As others have noted you are using slow-by-slow (row by row processing). Let's assume that PL/SQL, the bulk collect and row-by-row is actually necessary.
Then you should be constructing the parent and child records into collections and then inserting them in BULK using FORALL.
1. Create a collection for the new parent rows
2. Create a collection for the new child rows
3. For each set of LIMIT source row data
a. empty the parent and child collections
b. populate those collections with new parent/child data
c. bulk insert the parent collection into the parent table
d. bulk insert the child collection into the child table
And unless you really want to either load EVERYTHING or abandon everything you should use bulk exception handling so that the clean data gets processed and only the dirty data gets rejected. -
How to insert into two differents tables at the same time
Hi
I'm newer using JDev, (version 3.1.1.2 cause the OAS seems to support just the JSP 1.0)
and I want to insert into two differents tables at the same time using one view.
How can I do that ?
TIA
EdgarOracle 8i supports 'INSTEAD OF' triggers on object views so you could use a process similar to the following:
1. Create an object view that joins your two tables. 'CREATE OR REPLACE VIEW test AS SELECT d.deptno, d.deptname, e.empname FROM DEPT d, EMP E'.
2. Create an INSTEAD OF trigger on the view.
3. Put code in the trigger that looks at the :NEW values being processed and determines which columns should be used to INSERT or UPDATE for each table. Crude pseudo-code might be:
IF :NEW.deptno NOT IN (SELECT deptno FROM DEPT) THEN
INSERT INTO dept VALUES(:NEW.deptno, :NEW.deptname);
INSERT INTO emp VALUES (:NEW.deptno, :NEW.empname);
ELSE
IF :NEW.deptname IS NOT NULL THEN
UPDATE dept SET deptname = :NEW.deptname
WHERE deptno = :NEW.deptno;
END IF;
IF :NEW.empname IS NOT NULL THEN
UPDATE emp SET empname = :NEW.empname
WHERE deptno = :NEW.deptno;
Try something along those lines.

Inserts into Global Temporary Table

SELECT * FROM AGENT_SILO.AS_TEMP_VALIDATE;So I wonder what else I'm doing wrong that's really obvious. Here's what i'm trying to accomplish and maybe there's a better way of going about it.
I have a trigger that is supposed to do some validation before the insert is allowed to go through. So here's my approach. I have a trigger fired when there's an insert into the AS_Employee_history table. This passes some of the fields from this insert into a proc (the id, a flag and a couple of dates). Within the proc, i create a global temp table, insert these passed values into the temp table. Then I have a cursor to basically copy the rows from the as_employee_history table that have the same id. Then I can do some selects on the temp table to see if it passes the validation.
I have outputs throughout for debugging and it gets to right after the inserts into the temp table, then the rest of the code doesn't appear to be executed. So it looks like it's failing at the execution of select statements on the temp table. Anything else obvious that I"m missing here?
Here's my proc.
PROCEDURE "PAS_VALIDATE" (STATUS OUT VARCHAR2, v_status OUT BOOLEAN, NEW_SBI_EMPLOYEE_ID IN NUMBER,
NEW_CURRENT_FLAG IN CHAR, NEW_EFFECTIVE_START IN DATE,
NEW_EFFECTIVE_END IN DATE)

Inserting into a base table of a materialized view takes lot of time.......
Dear All,
I have created a materialized view which refreshes on commit.materialized view is enabled query rewrite.I have created a materialized view log on the base table also While inserting into the base table it takes lot of time................Can u please tell me why?Dear Rahul,
Here is my materialized view..........
create materialized view mv_test on prebuilt table refresh force on commit
enable query rewrite as
SELECT P.PID,
SUM(HH_REGD) AS HH_REGD,
SUM(INPRO_WORKS) AS INPRO_WORKS,
SUM(COMP_WORKS) AS COMP_WORKS,
SUM(SKILL_WAGE) AS SKILL_WAGE,
SUM(UN_SKILL_WAGE) AS UN_SKILL_WAGE,
SUM(WAGE_ADVANCE) AS WAGE_ADVANCE,
SUM(MAT_AMT) AS MAT_AMT,
SUM(DAYS) AS DAYS,
P.INYYYYMM,P.FIN_YEAR
FROM PROG_MONTHLY P
WHERE SUBSTR(PID,5,2)<>'PP'
GROUP BY PID,P.INYYYYMM,P.FIN_YEAR;
Please help me if query enable rewrite does any performance degradation......
