Should the following code work? I feel like I have done this before, but I'm getting a "must be a subquery" error now.
update TABLE1
set (FIELD1, FIELD2) =
values(select 'blah','blah' from DUAL)
where PK_FIELD=12345;
If this is invalid, is there another way to hardcode a series of values like this?

What I'm trying to do is make it so that it returns 'MATCH' when I pass a date that matches a date every two weeks starting Jan 01. Like Jan 01, Jan 15, Jan 29, Feb 12, etc. would return as MATCH Jan 02, Jan 03, etc. would return as NO_MATCH
The part in bold is what I'm having trouble figuring out.
select nvl(
(select 'MATCH'
from dual
where 'date' = '2 week intervals starting Jan 01'
), 'NO_MATCH') from dual

I have a package function which is wrapped and I cannot see the code.The package function raises an user-defined exception when :
SELECT ABC.*
FROM ABC
WHERE ABC.A = PACK.FUNC(ABC.B,ABC.C)
But it does not raise any exception and the query works absolutely fine generating desired results when :
SELECT ABC.*
FROM ABC
WHERE ABC.A = (SELECT PACK.FUNC(ABC.B,ABC.C) FROM DUAL)

I have ORACLE XE 11g installed on two machines and have been trying my luck to get my local db to query/insert/update a table from the remote db.
I have created the public database link and querying the dba_db_links shows that the links is successfully created (see the bottom of the post). I have also created synonyms for my remote table and queries like select name from jforum_forums succeed, with jforum_forums being a public synonym referring to user.jforum_forums@corona.magic.ubc.ca.
However when I try to insert a row into the remote table, there is a query to the remote DUAL to fetch the last generated ID for a given table similar to the following: SELECT jforum_forums_seq.currval FROM DUAL. Statements of such fail and they either throw an ORA-02019: connection description for remote database not found or ORA-01729: database link name expected. I tried including the database link with the name of the table making it like SELECT jforum_forums_seq.currval FROM DUAL@corona.magic.ubc.ca but that didn't work either.
PS, I should mention that global_names are set to true in both databases and that my database link has the same name as the global_name of the remote database.
OWNER

DB_LINK

I am trying to understand the difference between using sequence.NEXTVAL from DUAL as against using it direclty in an INSERT statment.
--Sequence Creation
CREATE SEQUENCE SEQ_ID START WITH 1 MINVALUE 1 NOCYCLE CACHE 500 NOORDER;
--Table1 Creation
Create table TABLEA (COL1 number, COL2 varchar2(10),
constraint COL1_PL primary key (COL1));
--Table2 Creation
Create table TABLEB(COL3 number);
alter table TABLEB add constraint COL1_FK foreign key(COL3) references TABLEA(COL1);
-- Option1 - Using sequence.NEXTVAL from DUAL
DECLARE
v_seq_num NUMBER;
BEGIN
SELECT SEQ_ID.NEXTVAL INTO v_seq_num FROM DUAL;
INSERT INTO TABLEA (COL1, COL2) VALUES (v_seq_num, 'test');
INSERT INTO TABLEB (COL3) VALUES (v_seq_num);
END;
-- Option2 - Using sequence.NEXTVAL in INSERT USING RETURNING INTO clause
DECLARE
v_seq_num NUMBER;
BEGIN
INSERT INTO TABLEA (COL1, COL2) VALUES (SEQ_ID.NEXTVAL, 'test') RETURNING COL1 INTO v_seq_num;
INSERT INTO TABLEB (COL3) VALUES (v_seq_num);
END;

i have two questions.
(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'
(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.

We have forms 11gr2 on win xp 32bit , weblogic linux server 64bit. We are converting 6i to 11g. Our system has many forms that span on 2 monitors. 1280x768 monitors, so some forms are 2560x768.
When alerts/messages pop up on the screen , they are positioned in the middle of both screens (guessing Oracle by default calculates width =2560/2, height =768/2).
Possible options:
1- is there a way to tell oracle to open alerts/messages a X Y coordinates? Maybe a config file on the server? Already file a Sr with Oracle tech support.
2- tried creating a form to do our messages. but this is flawed since when you call the new form to display the message, then the focus on current form is lost. when the message form is closed (then trigger when_window_activate fires)...this would be hell to try and control all our messages (we may have 20-30 on each big form. We have a total of 118 forms. Lots of messages with Y/N/Cancel options.
3- Maybe create a place holder for messages on all forms (bottom of screen)...thats the best idea we have so far.
4- Is there a way to do something with a java beans? We already have some knowledge with beans since we use image beans and pdf beans.

if a table contains two columns and both are part of the primary key of that table (Kind of obvoius).
should i opt for a index organized tbale in this case ?Or should i opt for another running sequential colum which would serve as a primary key of this table and define the actual two columns of the system as unique keys.
there is a drawback if a most of the tables of a database contain composite primary keys?

I am trying to join column names from a table with data from a different table. I think i should be able to pass the parameter to a 'select list' in a query. Look at my sample data below. And the data in sales table can grow till 15 rows and similarly corresponding columns in saleshist.
CREATE TABLE SALESHIST
(
PRODUCT VARCHAR2(30 BYTE),
Q1 VARCHAR2(30),
Q2 VARCHAR2(30),
Q3 VARCHAR2(30),
Q4 VARCHAR2(30)
)

I have two table country and state.Columns are given below
SQL> DESC Country
Name Null? Type
----------------- -------- --------------
PRIMARY_KEY NOT NULL NUMBER
DISPLAY_ORDER NOT NULL NUMBER
NAME NOT NULL VARCHAR2(50)
TREE_POSITION NOT NULL VARCHAR2(250)
PARENT_ID NUMBER
SQL> desc state
Name Null? Type
----------------- -------- -------------------------
PRIMARY_KEY NOT NULL NUMBER
DISPLAY_ORDER NOT NULL NUMBER
NAME NOT NULL VARCHAR2(50 CHAR)
VALUE NOT NULL VARCHAR2(50 CHAR)
TREE_POSITION NOT NULL VARCHAR2(250 CHAR)
PARENT_ID NUMBER
Now I have to insert the values in the state table taking from the country table.
EXAMPLE :
INSERT INTO STATE (PRIMARY_KEY, DISPLAY_ORDER, NAME, VALUE, PARENT_ID, TREE_POSITION) VALUES (251, 1, 'Alaska', 'AK', 233, 'STAT_USUS_AKAK');
but here the tree position is static it can be anything at the client side so I want to make it dynamic. So to make dynamic what I have used is mentioned below:
INSERT INTO STATE
(PRIMARY_KEY,DISPLAY_ORDER,NAME, VALUE,
PARENT_ID,
TREE_POSITION)
VALUES
[code].....
Now I want that Quote: select tree_position from L_STATE_ITEM where name ='United States')||'_ALAL' which i have used in the state table to put value in the tree_position, I want to make the other half part after the concatenation operator "_ALAL" also dynamic.
So I was just wondering If I can pic that value from the "VALUE COLUMN" of the same table.

Now, the requirement is to get the values which are inside the innermost square brackets.Such as in
First case : 123412
Second one: werer34
Third : qw2_w3rt
Only the values inside are needed. Is there any way to achieve it using Pl-Sql or just using Sql ?

I have one table which has 90 columns all has varchar2 datatype except one Column[primary key (Number)]. In this Table we have 1000 records, I want to fetch those records from Table which has value in all 90 columns means there is no null value in any column.
I know simple method Like this :-
column_name1 IS NOT NULL AND Column_name2 IS NOT NULL.
Like this we can write IS NOT NULL condition for all column.Is there any other way to write this Query because it makes Query very longer and it is very tedious job to write this Condition for all Columns.
