I have 2 tables with 3 common columns (Col1, col2,Primary). One common column name is primary (oracle key word).Around 2 lakhs rows to be updated and No indexes are used on these tables. I need to write an update query as shown below.
Emp table
Col1col2primay
100101y
103104n
201105y
100101y
Dept table
Col1col2primay
100101null
103104null
000656null
Update query Result
Col1col2primary
100101y
103104n
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.
I have one doubt about update command in sql. How to update the multiple rows with different values using update statment.
Eg:-
SQL> set linesize 500;
SQL> set pagesize 500;
SQL> select * from emp;
SQL> select empno,ename,sal from emp;
SQL> select empno,ename,sal from emp;
EMPNO ENAME SAL
---------- ---------- ----------
7839 KING 5000
7698 BLAKE 2850
7782 CLARK 2450
7566 JONES 2975
7654 MARTIN 1250
[Code]....
The above table contains 14 records. Now i would like to update the salary column with different values like
EMPNO SAL
===========
7839 18000
7698 20000
7782 5000
...
...
...
7934 25000
How to update above values with single update query.
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)
)
[Code].....
I have a query that is pulling back more rows when I use the dblink than when I hit the linked database directly.
For example:
select
x,y,z
from
mytable@dblink
returns 788,324 rows
while
select
x,y,z
from
mytable
returns 712,102 rows
It's the exact same query, with the only difference being the dblink. It's not pulling the data into a cursor or array, it's a simple, straightforward query on a remote database.
getting sql query to get the result below.If the Key repeats then I need to set it to O if for each key New_link doesnot match.
My Present table
Key New_Link
1 4
3 2
3 5
5 1
5 1
RESULT
Key New_Link

View 4 Replies View RelatedIn 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:

creation_date - string ('YYYYMMDDHHMI'),

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?

Table being updated CI_ADJ_CHAR column CHAR_VAL_FK1
Table from which values will be used CK_ADJ columns (cx_id, ci_id)
The CI_ADJ_CHAR.CHAR_VAL_FK1 values match CK_ADJ.CX_ID and should be updated with the value CK_ADJ.CI_ID.
The CK_ADJ table has 1.3 million rows and both the columns have indexes defined. Table definitiuon mentioned below
The CI_ADJ_CHAR table has 14 million rows and will update 1 million rows and has an index on the ADJ_ID column but not on the CHAR_VAL_FK1 column.
Is there any way i can Get how many rows are processing with UPDATE statement while the Update statement is still running.

SELECT tree.node_id, LEVEL depth_level
FROM tree_of_nodes nodes
START WITH nodes.node_id = 1000
CONNECT BY PRIOR nodes.node_id = nodes.parent_id
I need to update a column called dept_level, which is essentially the same as Oracle's LEVEL. Something like this statement is what I need, but obviously this statement doesn't work:

Device_id - Replaced_device_id - remove_date :: For group_id=10
e.g. for member_id = 1, device_id=123 got replaced by device_id=456 on 28-May-12
device_id=456 got replaced by device_id=789 on 01-Jun-12
So output should look like this
10 123 456 28-May-12 -- Replaced
10 456 789 01-Jun-12 -- Replaced
10 789 -- Active
Similarly there will be many groups, so it should list based on group_id
I've just started with the Oracle SQL and come from a heavy MS SQL background and I understand that here are some natural differences in the syntax but I'm stumped as to why the following sql represents a problem:
update MASTERMICODES t1
set t1.TEMPTA = ( select t2.TAFCODE
from TA_FEATURES t2
where t2.FCODE = t1.FCODE
)
It returns Error report:
SQL Error: ORA-01427: single-row subquery returns more than one row
01427. 00000 - "single-row subquery returns more than one row"
*Cause:

I want it to return more than one row...in fact I want it to make on all rows that have the same fcode between tables.
I am looking to build a query to update a current value in a DBA view to a new one.i.e. updating directories based on the current value:
CREATE OR REPLACE DIRECTORY 'DIRECTORY_NAME' AS 'DIRECTORY_PATH'(substr(directory_path, 1,5) + '/&dbname' {i.e. this is different for every database name }+ 'DIRECTORY_PATH'(string after /xyz/)
WHERE DIRECTORY_NAME in
( select DIRECTORY_NAME
from DBA_DIRECTORIES
WHERE DIRECTORY_PATH
like '/xyz/%'
)
i.e. resulting output should be:
CREATE OR REPLACE DIRECTORY 'ABC' AS '/xyz/DBNAME/abc/def/';
(when the directory previously was 'xyz/abc/def/') i.e. basically inserting the db name into the directory.where DBNAME is a variable more directories are added frequently so therefore this needs to be a dynamic procedure to change the directories in the db.
The requirement is I have a table (TAB1), wherein I have 3 columns, ID, LID and STATUS.
The value in ID column = ID_SEQ.NEXTVAL,and LID will be either 0 or 1 and the possible values for STATUS are 'ED','CP', NULL. The ID column is not suppose to have duplicate values, but there is no check on the table for the same.
Someone has updated the existing data and ID column is containing duplicate values. Wherever LID = 0 and STATUS = NULL and if only if ID is duplicated then the ID_SEQ.NEXTVAL has to be assigned to ID field, so that there are no more duplicate values.
CREATE TABLE tab1 (id NUMBER , lid NUMBER, status VARCHAR2(10));
Existing Data
------------------
INSERT INTO tab1 VALUES (1,0, 'ED');
INSERT INTO tab1 VALUES (1,0, 'CP');
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
INSERT INTO tab1 VALUES (1,0, NULL);
