I am trying to update a column based on another column in the same table (student table) and a column from another table (school table)
Code is:
update student_table
set student_code =
(select l.student_code
from school_table l, student_table n
where l.school = n.schoolname)
I get the following error ORA - 01427 Single-row subquery returns more than one row.
We had two tables.
Table 1: matusetrans
ITEMNUM Location Quantity transdate
AM1324 AM1 2 12-4-12
AM1324 AM1 2 15-5-12
AM1324 AM1 3 10-6-12
AM1324 AM1 4 5-1-13
[Code]....
Table 2: Inventory
ITEMNUM STORELOC lastyear currentyear
AM1324 AM1 need sum(quantity) here need sum(quantity)
AM1324 AM2 need sum(quantity) here need sum(quantity)
We have to update the last year and current year columns with sum of quantities for each item from matusetrans table based on date at different location in Inventory table.
we had nearly 13,000 records(itemnum's with different location) in inventory table in DB we have to update entire records.
How to write an sql queries to update lastyear and currentyear columns with sum of quantities based on itemnum and location in Inventory table

Actually I need update statement some thing like below scenario...
I explained my problem cleary in attached PDF since i cannot format text well here..
i have two questions.
(1) how can i fill some value in a table column based on some existing column value automatically without user intervention. my actual problem is i have 'expiry date' column and 'status'. the 'status' column should get filled automatically based on the current system date. ex: if expiry date is '25-Apr-2011' and current date is '14-May-2011', then status should be filled as 'EXPIRED'
(2)hOw can i build 'select' query in a report (report 6i) so that it will show me list of items 'EXPIRED' or 'NOT EXPIRED' or both expired and not expired separately in a single report based on user choice. 'EXPIRED' & 'NOT EXPIRED' can be taken from the above question no. 1.

I was trying to update the AGENTS table with the data based on queries. But all the records updates with the same data. I can't understand why.
Write a PL script to populate these columns as follows:
TRAVEL_STATUS is one of three values:
GLOBETROTTER: agent has visited five or more different locations in the course of his missions
ROVER: agent has visited between one and four locations
SLOB: agent has been on no missions.
CONTACTS is the number of targets that share the agent's home location.
some of the tables and columns are
agents table: agent_id, location_id
targets table: target_id, location_id
missions_agents table: agent_id, mission_id
missions_targets: target_id, mission_id
missions table: mission_id, location_id
My code is
DECLARE
status AGENTS.TRAVEL_STATUS%TYPE;
contact AGENTS.CONTACTS%TYPE;
CURSOR loc_cur
IS
SELECT

I have two tables lets say TAB_A and TAB_B. I altered table B to include a new column from table A I wrote a merge statement as follows to merge the data
MERGE INTO TAB_AUSING TAB_BON (TAB_A.SECURITYPERSONKEY=TAB_B.SECURITYPERSONKEY)WHEN MATCHED THEN UPDATE SET TAB_A.PPYACCOUNT=TAB_B.PPYACCOUNT;
I know INSERT is for inserting new records UPDATE to my knowledge is to modify currently existing records (loosely) MERGE is one I rarely used, until this particular scenario. The code works perfectly fine, but I was wondering how could I write an update statement? Or in this scenario should I even be using an update statement?

I used to have two tables to store details of PROPERTIES e.g UNIT_COMMERCIAL , UNIT_RESIDENTIAL. I need to combine both of them into one table called UNIT. I moved the data to the new table, but now I am stuck how to update the values of the child table which called MARKETING.
---
Now, I have two tables:
MARKETING (ID NUMBER PK , OLD_UNIT_ID NUMBER FK ...)
UNIT (NEW_ID NUMBER PK , OLD_UNIT_ID NUMBER ... )
I need to update the value of OLD_UNIT_ID in Marketing table to be equal to NEW_ID in the table of UNIT. As you can see the values of OLD_UNIT_ID in both tables are the same.
I used this statement
update ( SELECT distinct M.UNIT_ID , U.OLD_ID , U.ID FROM MARKETING M INNER JOIN UNIT U ON (M.UNIT_ID = U.OLD_ID)) set unit_id = idBut I got this error:
ORA-01732: data manipulation operation not legal on this view??
in one of the data base some of the column values are TE. i wanted to serch in what are the tables this TE values are present. so m running the below function

v_where VARCHAR2(4000);
v_first_col BOOLEAN := TRUE;
[code]....
but v_where := v_where || ' or ' || r.column_name || ' like ''%' || val || '%''' is giving me numaric or value error when i run as select find_in_schema('@TL') from dual; so how can i go ahed with the serch ?
i need an sql query or procedure to find out table name based on the column name..
View 4 Replies View RelatedI have table with values :

For the column all possible values are ( P102,P101,P103 etc toP124). I want to create a view ( if possible ) from the above with data output as :

basically this view has columns based on the previous tables column ( MEASURE_ID) values and the values will be corresponding value in column Percentage.

I am trying to update records in the target table based on the records coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. Looking at the informatica session log I find that the informatica code is perfectly fine but its in the update part it takes long time (more than 5 days to update one million records). find the TARGET TABLE query and the UPDATE query as below.
TARGET TABLE:
CREATE TABLE OPERATIONS.DENIAL_REGRET_FACT
(
CALENDAR_KEY INTEGER NOT NULL,
DAY_TIME_KEY INTEGER NOT NULL,
SITE_KEY NUMBER NOT NULL,
RESERVATION_AGENT_KEY INTEGER NOT NULL,
LOSS_CODE VARCHAR2(30) NOT NULL,

I am facing some challenge while running update query on newly added column in existing table.
Environment Details

Below are the step i followed.
1. In table testtablename, I have added new column COLUMNNAME29 with datatype VARCHAR2(8).
2. After adding the new column, i executed the update query to populate the data form COLUMNNAME1 to COLUMNNAME29.
3. The query is executed using COLUMNNAME24 in where clause, to drive query in index based.
SQL> desc testtablename

Problem faced & My analysis
1. The update query is hanging in database, it's not progressing (In single update, approximately 40000 records will get update)
2. No oracle error thrown in alert log or in session where the query being executed.
3. The event for the query is "db file sequential read".
4. When i update the newly added column COLUMNNAME29 with static value "1", the update completed successfully in few seconds.
5. Then i changed the static value to "1111" and executed the update statement, which result to query hanging in database.
6. I tried to update the existing column(COLUMNNAME1) in table with static value "1111", the update completed successfully.
Below are the queries completed successfully
Update Testtablename
Set Columnname29 = '1'
Where Columnname24 >= To_Date('01-12-2002 00:00:00', 'DD-MM-YYYY HH24:MI:SS' )
