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 understand what the message "subquery returning multiple rows" means but I have a case where I'm not 100% sure why it's happening to my update query (which in turn probably means I don't fully understand what's going on behind the scenes)
Here is my query:
Update A set (A.id, A.alt_name, A.min_rank)= (SELECT B.id, B.fullname, MIN(B.nm_rankval) FROM B, A WHERE A.id = B.id AND A.name <> B.fullname AND B.nametyp = 'ON' GROUP BY B.id, B.fullname) ;
The subquery returns 6 rows but they are all unique in terms of the id, name, rankval, etc...I naturally thought that the update statement wouldn't have a problem with this since the subquery is returning rows that are not duplicates and match one for one between table A and B. I used the group by to ensure I return unique values from table B (which does have duplicate id values)
Each of those 6 rows from the subquery of table B can be matched 1-1 with table A...so what am I missing.
I am working on a script in which I want to retrieve multiple rows but I get error ORA-1422.I tried solving it using the following script , but it still gives error.
CREATE OR REPLACE PROCEDURE proc_query DECLARE TYPE all_dest IS TABLE OF NUMBER; destIds all_dest; BEGIN SELECT dest_id from sb_packet WHERE src_id = 32; RETURNING dest_id bulk collect into destIds; END;
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'm getting back more than I want. I need to get the latest row in the PS_ACAD_STDNG_ACTN that has the academic standing code for students.
I thought if I max the effdt, strm, and effseq I would get back only one row. Especially effdt since a academic status is hardly ever updated on the same date.
PS_NTSR_GF_STUFILE will have multiple emplid's for students taking classes. PS_ACAD_STDNG_ACTN should have the last standing status for each student..(PRO = Probation, DIS = Dismissed).
UPDATE PS_NTSR_GF_STUFILE a SET a.NTSR_GF_ENRL_STAT = nvl(( SELECT b.GBSA_SUB1 FROM PS_GBSA_DTL b, PS_ACAD_STDNG_ACTN c WHERE c.ACAD_STNDNG_STAT = b.GBSA_VALUE
In a pl/sql procedure, when I am doing an update, I need the old value to be returned and stored in a local variable, so that the same can be used for future purpose.
Note : I know the "OLD:" option is present when we use TRIGGER, but in my case , the table I am updating is a old table and I am not permitted to create a trigger for it.
I have two update queries in the same Proc. One Seems to run just fine, the other I am getting this error:
ORA-01427: single-row subquery returns more than one row
The working Updates' structure is the same as the erroneous one. This works:
UPDATE P0525_STOREROOM_HOLDER H SET H.STRATIFICATION_ID = (SELECT X.STRATIFICATION_ID FROM EMISTRATIFICATION_XS X WHERE H.TOA = X.TOA AND H.STOREROOM = X.STOREROOM AND H.NSN = X.NSN AND X.ASSEMBLY = 'NO REQUIREMENT' );
This one gives me a single-row error:
UPDATE P0525_STOREROOM_HOLDER H SET H.STRATIFICATION_ID = (SELECT X.STRATIFICATION_ID FROM EMISTRATIFICATION_XS X WHERE H.TOA = X.TOA AND H.STOREROOM = X.STOREROOM AND H.NSN = X.NSN AND X.ASSEMBLY = 'ABOVE ALLOWANCE' AND H.NSN_QUANTITY > 0);
I have run a check on the data and there doesn't appear to be any duplicate values in the second update... Both Updates are supposed to be updating record sets not a single row (i.e. the stratification_id where the criteria matches...
I have a function in PL/SQL that uses CTE to obtain several strings. I need to return those strings to C#, either as a Return Value or a OUTPUT parameter.
I've managed to do that using PLSQL Associative Array, but it has the unnecessary usage of Array Bind Size, and I do not need to know what will be my Array size. Is that any other way to do it?
My Package is the next one:

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: *Action:
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.
The following code is indicative of what I'd like to do (as in not correct at all ). Would there be a more immediate way to accomplish this other than executing a SELECT statement after the UPDATE?
-- Incorrect indicative example 1.
DECLARE v_cur SYS_REFCURSOR; BEGIN UPDATE table1(f1, f2) SET ('v1', 'v2') WHERE f3 = 'v3' RETURNING <updated_rows> INTO v_cur END;
-- Incorrect indicative example 2.
DECLARE v_cur SYS_REFCURSOR; BEGIN OPEN v_cur FOR UPDATE table1(f1, f2) SET ('v1', 'v2') WHERE f3 = 'v3' END;

I'm trying to write a query that counts how many sessions are active during a 1 second time interval, then returns the maximum number of sessions active during any time interval, and all the time intervals that hit that max.
I don't understand why the custid is the same for each customer, and why it's selecting every customer and not just those with more than 150 gallons ordered.
For this one use the oil tables that you set up and use a subquery. Select the minimum average fall use from the house table. Then show all customers whose number of gallons delivered times two is greater than the minimum.
How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5 23 asdc 1 Location USA NM ABQ Four Seasons 87106 23 asdc 1 Stats 2300 91.7 8.2 85432 23 asdc 1 Audit 1996 June 17 1200 65 affc 2 Location USA TX AUS Hilton 92305 65 affc 2 Stats 5510 42.7 46 9999 65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type. For example for Information_Type=Location
Attribute_1 means Country Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime 23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200 65 affc 2 USA TX AUS Hilton 92305 5510 42.7 46 9999 1996 July 172 1100
i am reading the columns value from different table but i want to update it with single update statement. such as how to update multiple columns (50 columns) of table with single update statement .. is there any sql statement available i know it how to do with pl/sql.
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 am attempting to select back multiple values for a specific key on one row. See the example below. I have been able to use the sys_connect_by_path to combine the fields into one field but I am unable to assign them to fields of their own. See the example below
TABLE DETAILS: Policy id plan name 111 A Plan 111 B Plan 111 Z Plan 112 A Plan 112 Z Plan
My desired result is to be able to show the output as follows
Policy ID Plan_1 Plan_2 Plan_3 111 A Plan B Plan Z PLan 112 A Plan Z PLan
I have a column "empno" in EMP table and "deptno" in DEPT table . I want to update both the columns with single UPDATE statement. With out a creation of stored procedure or view(updating it through view).
Desired Output: ====== First Second Third 11 21 31
I have tried the below query SELECT DECODE (name,'Nexus', parameter) First, DECODE (name, 'GPlay', parameter) Second, DECODE (name, 'Demo', parameter) Third FROM (SELECT name, parameter FROM TableA where name in ('Nexus','GPlay','Demo'));
This gives me the output
First Second Third 11 <Empty> <empty> <empty> 21 <empty?> <empty?> <empty?> 31
Is there any way to get the output in single line.
tried searching google and this site too, found postings on WM_CONCAT, STRAGG, concat_all, LISTAGG functions by Michel and have experimented with these, but either the syntax is giving me a hard time or i just have not got the concept down.
Trying to get 2 rows into one. Have provided the create statements and insert of data. Also below will show what is returned with a Select i have and what is ideally required.
CREATE TABLE Person_Lang ( Person_ID NUMBER NOT NULL, Language_ID NUMBER NOT NULL, Contact_Name VARCHAR2(255 CHAR), Main_Phone VARCHAR2(255 CHAR), Secondary_Phone VARCHAR2(255 CHAR),
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)
and I want to insert First Name and Second Name records using the ID as the reference. The new data is currently in a .csv file, but I could put them in another table if that's easier.
ID|First Name|Second Name 1|Adam|Adamson 2|Ben|Benson 3|Chris|Christophers 4|Dave|Davidson
I understand how to do individual updates, I want to know how it is possible for me to do this as one query, as I have several thousand records to update.
