Oracle SQL - Update Table Value By Matching Columns
Mar 15, 2010
I have two table and trying to update tableA with data from tableB but gives an error. My TableA has columns - colA,colB,colC,colX and table B has columns - colA,colB,colX. Sample data looks like this:
this is the query I wrote
update tableA a
set (a.colX)=(select (b.colX) from tableB b where a.colA=b.colA and a.colB=b.colB);
When i run it gives this error:single row subquery returns more than one row.
tableB has only 1 value for colX for each colA,colB record but tableA has mutiple colA and colB repeated but for all of thsoe in table A i want to update the tableB.colX value for matching colA and colB.
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 need to display the record when all the columns have matching records,If one of them doesn't match then it should not be displayed
The following is the example
WITH t1 as (select 159435 ky from dual) ,t3 as (select 78 id ,'Z-' rk,'SL' cd from dual union all select 78 id ,'Z+' rk,'SL' cd from dual union all select 78 id ,'Z-' rk,'SL' cd from dual union all
[code].....
In the above data bg.rk= 'Z-' but one of the record in T3 is having Z+ ,So this should not be displayed (same condition with column CD) in this example cd column in both table matches I tried like above query but i'm getting the record.
I am trying to update columns of Table A with the columns of Table B. Both these tables have 60,000 rows each. I tried this operation using following 2 queries:
Query 1
Update TableA A set (A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3 from TableB where A.CODE=B.CODE)
Query 2 Update TableA A set (A.col1,A.col2,A.col3)=(select B.col1,B.col2,B.col3 from TableB where A.CODE=B.CODE) where exists A.code = (select B.code from TableB B where A.code=B.code)
When i execute these two above queries, it keeps executing indefinitely.
I am having issue with Oracle reserved words, one of the application is using table which has NUMBER as column. I am not able to query that table matching database with NUMBER column.

I need to take a snapshot of a table before insert or update happens to that table.... in oracle 10g. I am reading the MV docs from oracle and below link..
[URL].......
how MV should be written for this and how to schedule it in dbms_jobs for auto refresh?
assuming that t1 is the table where DML operation are goin to happen so before any insert or update, snapshot has to be taken, and I am assuming that to do this it would look something like this?
create materialized view my_view refresh fast as select * from t1;
I was trying to insert a row into Oracle database consisting 20 columns through IBM Web Experience Factory. I am getting "Array index out of range: 20" error message. To my knowledge insert is working fine till 7 columns. Is it a driver problem or do i need to install any fix pack?
my need is to perform merge - update when id column is matched, but one of others columns not.When id column is not matched then I perform insert.
It works fine for matched or not matched id column.
Commented code is my try to perform check for others columns, The code should not update when all columns match. It should update only when on of columns doesn't match (except id column of course, because it's key column).
begin merge into copy.table1 rr using ( select ID , DEALID , ESTIMATIONDATE , BOUNDOVERESTIMATDATE , ESTIMATIONTYPEID , MARKETAMOUNT , LIQUIDATINGAMOUNT , [code]....
I need to write a script which copies 4 col data from one table to another table. there are three tables
cwat_curr_mst and cwat_assigned_customer and cwat_assignment_mst. Cwat curr mst has PK curr_id and cwat_assigned_customer has PK assignment_id. Also cwat_assigned_customer has customer_id. In cwat_assignment_mst has Curr_id and Assignment_ID.
cwat_curr_mst and cwat_assigned_customer tables has 4 cols in common they are ASRT_SNM_NO, SNM_NO, FLORIDA_NO, CBRN_NO.
So from curr_mst all these 4 cols data needs to come/copy into cwat_assigned_customer.
Now I tried to use following SQL to update WORKID & STATIONID columns in TABLE2 but failed. BUS_FID in both tables have been UNIQUE indexed and they can be used as primary keys to join these two tables.
I am trying to develop a form consisting of a key block and a single data block. The problem is that the driving table is not the table that needs to be updated.
user wants the following layout:student Advisor ID# name degree major Concentration ID# name The driving table (TABLE A) will supply the first 5 fields. The advisor ID comes from (TABLE B).
The user needs to update the adviser ID# field associated with the student ID# field. The form is to be tabular listing all students. I've seen some info on using procedures to insert, delete, update, query and lock tables, but i'm just not sure if that's what is needed.
how to use APEX_ITEM.text for where the source for this comes from user input values and not for an underlying table.I have a report where three columns are coming from an actual table (one being a checkbox for selection) but then also have two additional fields on the screen that are not from a table but placeholder fields for user's to enter data.
For example, my query looks like this:
select apex_item.checkbox2(10,id), name, telephone, apex_item.text(20,NULL) as "Date Contacted", apex_item.textarea(30,NULL,5,80) as "Comment" from my_table
I am not seeing any values for the two user fields when entering values and doing a view source?
I have more than 10 lakhs records in the table for which i am going to update two columns without any filtration. i have pasted my query in it..it's taking more time to update..is there any way to fine tune this block.
I am trying to update multiple columns from one table based on the results of another table So I have 3 tables as follows
HISTORYSUMM_SNAPADM_CHOICE My SQL code is loosely SELECT SUM(H.HIS1), SS.SNAP1, AC.ADM1FROMHISTORY H, SUMM_SNAP SS,ADM_CHOICE ACWHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2GROUP BY SS.SNAP1, AC.ADM1
This works, and I am able to SUM the column as I need with the right numbers. I altered the SUMM_SNAP table and now I want this summarized column to be in the table I tried using UPDATE, but there is no FROM clause to let me do the table join/group by
UPDATE SUMM_SNAPSET SUMM_SNAP.SNAP3=SUM(H.HIS1)FROMHISTORY H, SUMM_SNAP SS,ADM_CHOICE AC WHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2 GROUP BY SS.SNAP1, AC.ADM1
The above is obviously wrong - but just trying to show whatI was thinking What would be the best method to get the numbers from the SUM into a table?
i have two tables test1 and test2. i want to update the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE v_mydept1 TEST1.DEPT_CD%TYPE; v_mydept2 TEST2.DEPT_CD%TYPE; CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR; [code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF" I am not sure what is the exact problem when we want to update multiple columns of different tables.
I am trying to update a table column values if any change occurs using bulk collect and for all update not able to get idea. below is the proc working out.it is for insert and update using the cursors.
CREATE OR REPLACE PROCEDURE PRC_INS(P_ID IN NUMBER,P_STAT OUT NUMBER) IS TYPE T_TEST_TAB IS TABLE OF T_DTLS%ROWTYPE; V_PARAM T_TEST_TAB; V_STATUS NUMBER; V_BUS VARCHAR2(20); V_UP VARCHAR2(1); V_Q VARCHAR2(50);
