SQL & PL/SQL :: Update All Rows At Once
Aug 28, 2011
I want to update salary column of emp table in a way that every value of salary column be increased by 1000, is this possible I can do this one statement only??
(Just FYI-
SQL> desc emp;
Name Null? Type
----------------------------------------- -------- ----------------------------
EMPNO NOT NULL NUMBER(4)
ENAME VARCHAR2(10)
JOB VARCHAR2(9)
MGR NUMBER(4)
HIREDATE DATE
SAL NUMBER(7,2)
COMM NUMBER(7,2)
DEPTNO NUMBER(2)
)

This is my query:
UPDATE t_tt_hours a
SET a.sak_request = (
SELECT b.sak_request
FROM t_requests b, co c
[Code]...
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
[Code]...
but it doesn't seem to make a difference. The reason I need to do this is that the difference between where it matches with a valid (non-null) value is 396 rows vs. 12,484 rows which is too time consuming to run on my page.

, im having this trouble to update some records, the problem is i have I have this table with some transactions and each row have a cd_cli (client code), dt_ven (date of the transaction) and a product id (cd_prod) the trouble is, i insert a row for each product in this table, then i have like this
110001YURI AGUIRREWALLMA400V44-B469,0019/9/2013210001YURI AGUIRRESU-7N-B78,0019/9/2013310001YURI AGUIRREWALLSF35V22-S78,5719/9/2013410003WILLIANWALLSA470V22-BS449,002/9/2013 but i need to update the CD_TRANS for each row with the same number like all the YURI AGUIRRE recode must have like CD_TRANS 1, and the WILLIANs CD_TRANS must be 2 and the next must be cd_trans 3, but I've tried to update the table for a lot of ways but i don't have success trying to do this, the last thing i had tried was
MERGE INTO TVEN_TEMP a
USING (SELECT CD_CLI, DENSE_RANK () OVER (ORDER BY DT_VEN) new_seq_num
FROM TVEN_TEMP
WHERE CD_TRANS IS NULL) b
ON (a.CD_CLI = b.CD_CLI)

In a table i have some duplicate rows
I can get it through this query : select PARTY_ID from XXWFS_CUSTOMER_EXT group by PARTY_ID having count (PARTY_ID) > 1;
Now for the records which i got for each duplicate row i want to update the second row with a specific value.. so that duplicate rows does not exist anymore
Ex: I got party id's 12, 14, 16, 18 two times each
Now as 12 is two times.. i want to update the second row of 12 with some x value same is the case for other values like 14,16, etc
how can i write a procedure for this

This is a surprisingly common one I've found on the web...even on devshed forum
I am updating one table from another (Updating Table A from Table B):
Table A
ID, Value
-- -----
1 A
1 A
2 B
Table B
ID, Value
-- -----
1 Animal
2 Box
Table A (modified)
ID, Value, Name
1 A Animal
1 A Animal
2 B Box
No I need to update a new column in Table A with the value in Table B.Value where the ID's from both tables match. Problem is: When I do this I get multiple rows and hence Oracle won't let me update this column. Now, I keep reading that for these types of updates, there has to be a one-to-one relationship...
Is this true...is there anyway of telling Oracle to update wherever it finds that ID, regardless of how many duplicate ID's there are?
This is quite a frustrating problem and most of the sites that I've looked for solutions try get the query one-to-one...problem is...with my table sets it's impossible to do that - I need to update wherever the id's match (even if it return multiple rows).

I have this requirement in Oracle FORMS ver 6i where I populate some records in a table in a datablock and display them on the screen. A facility needs to be provided to the end users to select the records randomly by just entering the count of the records in a non-d/b text field. The number entered in the count field will decide how many records are to be selected randomly.
I tried using the query -
UPDATE <table a>
SET <col 1> = <value 1>
WHERE rowid IN (SELECT rowid FROM (SELECT * FROM <table a> ORDER BY DBMS_RANDOM.VALUE)
WHERE <col 2> = <value 2>)
/
which I found on the link [URL] but while compiling, the Form gives a compilation error for the ORDER by clause - i'm sure there's no syntax error in the way I have written it...

Assume that we have table Test with a column TestId and Status. This table is having 10,000 records. Now, we need to write a stored procedure that does the following:
1) Select top 10 rows whose "Status = NEW'
2) Update the selected top 10 rows with "Status = PROCESSING"
3) Return those top 10 rows.
Assuming there are hundreds of such requests coming to Oracle database, how can we make sure each request NEVER gets a duplicate record at any given point of time and how to fetch the records that have been updated individual request?

Updating multiple ROWS with different values using single statement. Requirement is to update one column in a table with the values in the other table.
Say we have 3 tables, CORPORATION,CORPORATE PROFILE and MEMBER.
Each MEMBER has CORPORATE PROFILE which in turn is associated with CORPORATION. Now I need to update MEMBER table with CORPORATION identifier for members who belong to corporations with identifiers say 'ABC' and 'DEF'.
MEMBER table contains column 'CORPIDENTIFIER '. CORPORATEPROFILE table contains MEMBERID and CORPORATIONID,this will associate a member with the corporation. CORPORATION table contains ID and CORPIDENTIFIER.
Using the below query I am getting error,ORA-01427:single-row subquery returns more than one row
UPDATE MEMBER M SET M.CORPIDENTIFIER=
(SELECT A.IDENTIFIER FROM CORPORATION A,CORPORATEPROFILE B
WHERE B.CORPORATIONID=A.ID AND B.MEMBERID=M.ID AND (A.IDENTIFIER LIKE 'ABC' OR A.IDENTIFIER LIKE 'DEF'))
Sub query in the above query returns multiple rows and hence it is throwing the error.More than one members are associated with Corporations ABC and DEF. Is there any way possible to update all the rows in single query with out iterating the result set of sub query.

I would like to update the complete flag of all the rows of a table except the most recent two rows of each category.
The table has fields like:
category - string,
item - string,
creation_date - string ('YYYYMMDDHHMI'),
complete_flag - boolean,
etc.
Each category does not have the same amount of records with the same creation_date so I do not want to filter by creation_date. Is there a way to accomplish this?

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 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;

After many tests I can't make work and update of the same table inside the same table.
Trying to avoid Mutating Table Error now I have
ORA-00036: maximum number of recursive SQL levels (50) exceeded
Sample Data :
create table test_compound (USERID VARCHAR2(10),APP VARCHAR2(15),LAST_UPDATED_ON TIMESTAMP);
insert into test_compound values ('user1','1',systimestamp);
insert into test_compound values ('user2','2',systimestamp-4);
insert into test_compound values ('user3','3',systimestamp-6);
CREATE OR REPLACE TRIGGER trigger_test
FOR UPDATE ON test_compound
COMPOUND TRIGGER
TYPE t_tab IS TABLE OF VARCHAR2(50);
l_tab t_tab := t_tab();
[code].......
When I execute :
update test_compound
set last_updated_on=systimestamp
where userid='user1' and app='1';
The trigger should update the first row and all the data from test_compound table where userid='user1'. Maybe the problem is that updating the same table inside the trigger is firing in a recursive way the trigger.
