Updating Multiple Records In A Table
Oct 29, 2012OS:Solaris
DB:10G
I have a situation where there are multiple records for a join criteria. I am trying to find a way to update a particular column for all the records returned by the join criteria. Example :
Table A
id number
1 1000
2 2000
3 3000
4 4000
Table B
id number
1 9999
1 9999
1 9999
1 9999
1 9999
1 9999
2 8888
2 8888
3 6666
3 6666
Result after update:
Table B
id number
1 1000
1 1000
1 1000
1 1000
1 1000
1 1000
2 2000
2 2000
3 3000
3 3000
update query ? When I use a update statement with where exists it errors out because the query returns more than one row for the join condition.

How To Add Sequence Column To Existing Table With Records
Dec 8, 2012I had created a new table named USERLOG with two fields from a previous VIEW. The table already consist of about 9000 records. The two fields taken from the VIEW, i.e. weblog_views consist of IP (consists of IP address), and WEB_LINK (consists of URL). This is the code I used,
CREATE TABLE USERLOG
AS
SELECT C_IP, WEB_LINK FROM weblog_views;
I want to add another column to this table called the USER_ID, which would consists of a sequence starting with 1 to 9000 records to create a unique id for each existing rows. I'm using Oracle SQL Developer: ODMiner version 3.0.04. I tried using the AUTO-INCREMENT option,
ALTER TABLE USERLOG
ADD USER_ID INT UNSIGNED NOT NULL AUTO_INCREMENT;
But I get an error with this,
Error report:
SQL Error: ORA-01735: invalid ALTER TABLE option
01735. 00000 - "invalid ALTER TABLE option"

Forms :: Updating Multiple Records
Mar 30, 2010I have a form with two data blocks, one parent, one child block.
The parent is holds mineral lease info while the child holds the mineral owner info, such as addresses and phone numbers. One owner can be in the owner block multiple times (different owner types). The form only displays one owner at a time.
We have a separate master owner table which holds owner address. (We set it up this way because we get electronic info from mineral companies that we have to load each year).
As you tab through the owner block, it checks the FEIN against the master table and pulls updated address info from the master table.
I have a problem in which if an owner is on the lease multiple times, when you tab through the first instance, it pulls in the new address info, but when you go to the next instance, it won't update. If you requery, it seems that the first update actually updated all the owner records on that lease. How can I turn this off?

Application Express :: Updating Records Within APEX?
Mar 11, 2013I've created a system for managing football within APEX and it is at a stage now whereby the user can view any number of the tables through Reports and insert data into these tables through Tabular Forms. Its using triggers and sequences to allow for new primary keys to be generated each time within these Tabular Forms so I'm at a stage now where I'm really quite pleased with it..
The last thing I'm needing to do now is have it update certain fields when certain records are entered.
Clubs
clubId
clubname
gamesplayed
clubPoints
clubtotalgoals
Results
club1 (clubId foreign key from clubs table)
club2 (clubId foreign key from clubs table)
club1goals (the amount of goals, type Number)
club2goals (the amount of goals, type Number)
club1points (points earned, Type Number)
club2points (points earned, Type Number)
When filling out a result, the user will enter the following (as an example):
club1 - 1 (club with ID, 1)
club2 - 12 (club with ID, 12)
club1goals - 2 (the first club scored 2 goals)
club2goals - 0 (the second club scored 0 goals)
club1points - 3 (the first club picked up 3 points)
club2points - 0 (the second club picked up 0 points)
The result is then entered into the results table and what I am hoping to achieve at this stage is the following:
1) in the clubs table, the gamesplayed is incremented by 1 for both clubs as a result of playing this fixture
2) club1 has however many goals club1 scored added to its current clubtotalgoals field (in this case, it is of course 2)
3) club1 has however many points club1 earned to its current clubPoints field. (In this case it would be 3)
Forms :: Updating Records Values And Post Trigger
Jul 15, 2013I have a multi record block based on a view. All records in the view are displayed in the block by use of Post-Query trigger when entering the form.
The block has 5 items as follows:
1) RECORD_STATUS = a non-base table column which is a checkbox.
2) ITEM_TYPE = a text-item which has an LOV attached.
3) ITEM_TEXT = a text-item which is free format text.
4) LAST_UPDATE_DATE a date column
5) STATUS = a text item either 'Open' or 'Closed'
The LOV is based on a table of Item Types with values say, 'Type1', upto 'Type9'.
I have a Wnen-New-Record-Instance trigger which 'Posts' changes to the database. This has been included as i want to limit the values of the ITEM_TYPE column to values which have not been previously used.
Consider this scenario...
The block has 3 records.
record 1 has 'Closed' status so no updates are allowed.
record 2 has 'Open' status so updating of Item_Text is allowed.
record 3 has 'Open' status so updating of Item_Text is allowed.
I check the RECORD_STATUS checkbox on record2.
(This sets the RECORD_STATUS checkbox to a checked value and changes the STATUS column to 'Closed' by When-Checkbox-Changed trigger.) At this point the record has not been saved so if you uncheck the checkbox , then the STATUS column will go back to 'Open'. However at this point i will leave it as Checked (Closed).
I then insert a new record, only values Item4 to Item 9 are correctly shown in the LOV. I select Item4.
I then go back to the previous record and uncheck the Checkbox to say that i wish to leave it 'Open' after all (in effect no changes have occurred), then the STATUS column correctly reverts back to 'Open' by my WCC trigger. If i then SAVE the changes, the new record has been inserted on the database correctly, however the LAST_UPDATED_DATE from the record which was checked and then unchecked has also been updated incorrectly even though no net changes have actually occurred.
(because i am using WNRI trigger to limit the List of Values on the LOV column, this has incorrectly set the previous records LAST_UPDATED_DATE column to be Sysdate.)
How can i stop this from happening?
SQL & PL/SQL :: Updating Column In Every Row Except For The First
Jan 16, 2012I am trying to find a way to update all of the rows in a table for a column EXCEPT for the very first row. I am not sure if this can be done while I enter my SET parameter or not. I have also thought about using an EXCEPTION in a stored procedure. For example, say I have the table listed below:
SQL> select * from example1;
CODE1 I_ID CODE2 J_ID NAME1 DATE1
----- -------------------- ----- -------------------- -------------------------------- ---------------
A 100 A 200 John 20111225
A 100 A 300 John 20111225
A 100 A 500 John 20111225
A 100 A 400 John 20111225
A 100 A 250 John 20111225
A 100 A 700 John 20111225
A 100 A 800 John 20111225
A 100 A 900 John 20111225
A 100 A 1000 John 20111225

A 100 A 1275 John 20111225
A 100 A 3000 John 20111225
12 rows selected
I am wanting to update the table so that if there were more than 3 J_id's on the table for the same I_id then it will set all of the code1's and code2's to a C except for the very first one. Such as:
SQL> select * from example2;
CODE1 I_ID CODE2 J_ID NAME1 DATE1
----- -------------------- ----- -------------------- -------------------------------- ----------------
A 100 A 200 John 20111225
C 100 C 300 John 20111225
C 100 C 500 John 20111225
C 100 C 400 John 20111225
C 100 C 250 John 20111225
C 100 C 700 John 20111225
C 100 C 800 John 20111225

C 100 C 1275 John 20111225
C 100 C 3000 John 20111225
12 rows selected
I have done some searches and haven't seen any results.

if i delete
delete from test where id=4;
then automatically.. "id" column values will again in sequence... like this

PL/SQL :: Updating A Column Randomly With Selected Values?
Sep 26, 2013 We've an accounts table that basically represents hotel chains & brands. an example shown below.
account_id chain_id brand_id service1
NULL NULL 111
NULL NULL 122
NULL NULL 11
Here I want to update the chain_id & brand_id which are currently NULL in order to make every row eligible for further processing.
There is another table(say chain_brand) which maintains the relationship between chain_id and brand_id. one chain_id can have multiple brand_ids eg.,
chain_id brand_id
101 2011 101
2012 102 2020
Now I need a script that could randomly pick values from chain_brand table and update the accounts table. condition is those values should be unique for an account_id eg.,
account_id chain_id brand_id service1
101 2011 111 101
2011 122 102 2020 11
so each account can be attached to only one chain_id and one brand_id.
Forms :: ORA-01461 When Updating A LONG-Column Via Trigger
Jul 5, 2010I have a non-base-table item which I want to update in the pre-update trigger of the current block.
If the content of the field exceeds 4000 characters, i get the error message
ORA-01461: can bind a LONG value only for insert into a LONG column.
The code is
update tab set long_col = :formsblock.long_col
where tab.tabpk = :formsblock.foreign_tabpk;
Workarounds would be,
1.) to delete the old dataset and insert the new one:
delete from tab
where tab.tabpk = :formsblock.tabpk;
insert into tab (tabpk, long_col) values
(:formsblock.foreign_tabpk, :formsblock.long_col);
or 2.) to change the Item from a non-database item to a database item and use the internal update of the forms-module, but both workarounds are not very satisfying.
Do you know another way to update the LONG-column within the pre-update trigger (or any other PL/SQL part of forms)?
