Join condition in an update statement

All,
This is what I want to do
update table1
set col1= (col2 from table 2)
for each row.
ie. Each row should be updated with the corresponding value in table 2.
Please help.
Let me know if more explanation is required.

Why do you want to update col1 with same value again? That's what your update is doing.
If your intention is different you can tweak merge as needed.
merge into table1 t1
using (select key to match with table1 , value
from table1, table2, table3
where table1.col1=table2.col2
and table2.col2=table3.col3) t2
on (table1.?? = t2.key to match )
when matched then
update set t1.col1 = t2.value;

JDBC adapter - update statement

I have come to the conclusion that there is no direct connection between the select and update statement of a sender JDBC adapter, in terms of commit scope.
According to SAP documentation:
"The UPDATE statement must alter exactly those data records that have been selected by the SELECT statement. You can ensure this is the case by using an identical WHERE clause. (See Processing Parameters, SQL Statement for Query, and SQL Statement for Update below)."
But my point is: if select statement retrieves e.g. 5 rows based on a where condition, then the update statement could find 6 rows to update, if a row was inserted a split second after the select, but before the update. Result : a row is lost...
I don't think the select statement puts a lock on the table(s) it accesses, and releases this lock after update has been committed. This would ensure integrity between select and update statement.
Can anybody confirm or deny this ?

Hi,
Have you seen the<b> Isolation level for Transaction handling</b> in the sender JDBC adapter?
Make the Isolation level as Serializable and repeatable Read and the db gets locked anbd until Update happens, no Insertion can occur in the Split Second!

Hi,
If all the values needed to update a given row of table_x are coming from the same row of table_y (or from the same row of a result set of a query involving any number of tables), then you can do something like this:
UPDATE table_x x
SET     (col1, col2, col3, ...)
=     (
         SELECT NVL (y.col1, x.col1)
         ,         NVL (y.col2, x.col2)
         ,         NVL (y.col3, x.col3)
         FROM    table_y y
         WHERE   x.pkey   = y.expr
         AND         ...
WHERE   ...
;If the WHERE clause depends on the same row of table_y, then it will probably be simpler and more efficient to use MERGE instead of UPDATE.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
In the case of a DML operation (such as UPDATE) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Yes, you can. The table with updateble columns must be a key preserved table. See http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96590/adg03sch.htm#1044

Update statement with joins

Hi all, consider the tables and data below
CREATE TABLE table1 (id NUMBER, a NUMBER, b NUMBER) ;
CREATE TABLE table2 (id NUMBER, c NUMBER, d NUMBER);
INSERT INTO table1 VALUES(111,2,0);
INSERT INTO table1 VALUES(111,1,2);
INSERT INTO table1 VALUES(111,1,3);
INSERT INTO table1 VALUES(222,1,3);
INSERT INTO table2 VALUES(111,5,8);
INSERT INTO table2 VALUES(222,6,7);
what i want to do is write a UPDATE STATEMENT that joins the two tables BY id
and update table1 rows. i want to include the following CASE statement
UPDATE COLUMN a intable1 according to this logic
case
WHEN b >0
THEN nvl(c,b)
ELSE
d
END
so table1 after the update should look like this
id    a   b
111   8   0
111   5   2
111   5   3
222   6   3can somebody help write a update statement that update table1 according to case statement and joins both tables to get the values necessary? thanks

Update statement with inner join

Hello everyone. I am am trying to do an update statement with an inner join. I have found several examples of SQL statements that work with Sql server and mysql but they don't work in Oracle. Does anyone know the proper way in Oracle 10G? I am trying to update all fields in one table from fields in another table.
for example:
UPDATE table3
SET
TL3.name = TL2.name,
TL3.status = TL2.status,
TL3.date = TL2.date
FROM table3 TL3 JOIN table2 TL2
ON (TL3.unique_id = TL2.unique_id);
any help will be appreciated.

Hi,
You can also use MERGE, like this:
MERGE INTO table3     dst
USING   (
         SELECT unique_id
         ,         name
         ,         status
         ,         dt          -- DATE is not a good column name
         FROM    table2
     )          src
ON     (dst.unique_id     = src.unique_id)
WHEN MATCHED THEN UPDATE
SET     dst.name     = src.name
,     dst.status     = src.status
,     dst.dt          = src.dt
;Unlike UPDATE, this lets you avoid essentially doing the same sub-query twice: once in the SET clause and then again in the WHERE clause.
Like UPDATE, you don't acutally join the table being changed (table3 in this case) to the other table(s); that is, the FROM clause of the suib-query does not include table3.
Riedelme is right; you'll get better response to SQL questions like this in the SQL and PL/SQL forum:

Update Statement Help Please

I'm coming from the MS SQL world LOL
and Im trying to write an update statement but in Oracle there is no INNER JOIN.
Can you give me some advice on how to do this please?

INNER JOIN tmpuser

Thank you for you help.

Hi,
AJR wrote:
Frank,
But when we are using the where condition it should update records with the matching ids. right?What your query should do is entirely up to you; I can't answer any questions about that, only you can.
I have faced this issue earlier.
WHERE       tmpuser.emp_id = employee.emp_idCan you explain?Not out of context. Post a complete statement.
If this isn't directly related to user9170886's problem, then it's better to start your own thread.
I can say a few things about UPDATE statements in general:
The WHERE clause governs which rows will be UPDATEd. If there is no WHERE clause, all rows in the table will be UPDATEd.
So
UPDATE     employee
SET     employee_name = ( <subquery> )
;UPDATEs every row in employee, because the UPDATE statement does not have a WHERE clause. Nothing in the sub-query can change that.
A sub-query can reference values from its immediate parent, but a parent can't reference values from a sub-query (other than the values actually returned by the sub-query, of course).
So
UPDATE     employee
SET     employee_name = ( <subquery> )
WHERE     tmpuser.emp_id     = employee.emp_id
;causes an error, because there is no table called tmpuser in the main UPDATE statement. Nothing in the sub-query can change that.

Copy records of one table into another using Update statement

Supposing I have 2 tables test and test1.
Test has columns col1 and col2. and test1 has only one table col1.
select * from test returns:
COL1 COL2
a
b
c
d
e
select * from test1 returns
COL1
p
q
r
s
t
Suppose i want to copy values of test1.col1 to test.col2 so tht final result of
select * from test should be
COL1 COL2
a p
b q
c r
d s
e t
I found a query in the OCP introduction book:
update test set col2=(select col1 from test11)
this works fine only when we have a single record in test1 table but fails otherwise.
how can this be achieved using the update statement ?

This will work only if you have the same number of lines in COL1 in both tables. If you have different number of lines, then you need to code more at join (outer, inner).
But for complicated cases, please post sample data.
Michael
PS: And supossing that the values are distinct in TEST table. Else update will fail, because more rows will be retrived.
If more values in TEST table in COL1, then you need to assign a row number on TEST also, and in WHERE of query you need to place one more join condition:
something like:
8* ) z where z.col1 = test.col1
and z.rn = test.rn)

But as i said, get more specifications.

How to create view that has an update statement

Tools: MS Management Studio SQL 2008 R2
Code:
Create View as Mocha
UPDATE dbo.Cola
SET Login_ID = Replace(PE15,RTRIM(Cast(Login_ID),'')
UPDATE dbo.cola
SET P4 = NullIf(P4,'')
I would like to create a database object "View" to hand it over to a user and run the script. How I would create a a view that would accept an update statement. Are any work around to accomplish this goal

Not quite sure what you want to achieve.
However, if your view displays rows from a single table and each row relates to exactly one row in the source table (no aggregates, no join, no transformation) then you can update it. The update will be executed on the table it refers to.
If you view is more complex, contains joins, aggregates and such, you can create a trigger on it to update the base table(s).
The conditions for a view to be updatable are a little more complex then what I wrote but you can find it here under "updatable view":
http://msdn.microsoft.com/en-CA/library/ms187956.aspx
In the end, you would have a view which displays rows and can be updated.
If all you want is to modify rows without viewing them then HuaMin Chen's solution is the one for you, create a stored procedure instead.

How do I pass multiple values from a text box to an update statement

I hope this does not sound to lame. I am trying to update multiple values Like this:
Code|| Computer Desc || Computer Price || Computer Name
SEL1 || Apple macbook || 1564 || Apple Macbook Basic
SEL2 || Dell 630 || 1470 || Dell Latitude
I want to change all six values at once in one update statement based on the Code, I can't find a good tutorial/example to help me.
Can anyone point me in the right direction?
Thanks so much,
Laura

You can do conditional updates with decode or case statements e.g.
SQL> create table t as
2 select 'SEL1' as code, 'Apple macbook' as comp_desc, 1564 as comp_price, 'Apple Maxbook Basic' as comp_name from dual union
3 select 'SEL2', 'Dell 630', 1470, 'Dell Latitude' from dual
4 /
Table created.
SQL>
SQL> update t
2 set comp_desc = CASE code WHEN 'SEL1' THEN 'Test1' Else 'Test2' END,
3      comp_price = CASE code WHEN 'SEL1' THEN 1234 Else 2345 END,
4      comp_name = CASE code WHEN 'SEL1' THEN 'Test1 Name' Else 'Test2 Name' END
5 /
2 rows updated.
SQL>
SQL> select * from t
2 /
CODE COMP_DESC     COMP_PRICE COMP_NAME

Update statement getting ORA-00904 invalid identifier

I am getting this ORA error when I try to conduct an update statement from a column value in one table to a like-named column in another table.
For instance, in my select, shown below, this query runs like a champ, returning all of my records
SELECT
b.ID,
b.ZIP, a.ZIP,
a.NAME,
a.LOCATION
FROM TBL_ARCHIVE a
INNER JOIN TBL_UAT b ON
a.ID = b.ID
WHERE
b.ID > 470000 And b.ID <470100;However, if I try to run an update statement with any of the following, I get this error. It seems so strange to me that I'd get an error using the same columns in the update statement, but would return the desired results effectively from the select statement!
one version of UPDATE
UPDATE TBL_ARCHIVE a
SET a.ZIP = TBL_UAT.ZIP
WHERE TBL_UAT.ID = a.ID;and another
UPDATE TBL_ARCHIVE
SET a.ZIP =
(SELECT b.ZIP
FROM TBL_UAT b
WHERE b.ID <472500 And b.ID >471000)
FROM TBL_ARCHIVE a
WHERE a.ID = b.ID)
WHERE ID IN
(SELECT ID
FROM TBL_UAT b
WHERE b.ID <472500 And b.ID >471000
);^ - this one produces a SQL not properly ended. Error ORA-00933: SQL command not properly ended.
I'm really unsure though, how what I thought was a fairly basic update statement wouldn't work. I'm using Oracle 11g but through either Toad or SQL Plus. I've gotten these same errors in both.
Though MS Access runs slow as snails, I can manage to run the update statement successfully with it, a thousand records or so at a time. Problem is, I've got about 300K records needing updating.
I've looked around for similar problems but haven't found one where someone wasn't either using a reserved word for a column, which I'm not, I don't believe, or a problem that really dealt with this error in the context of an update statement.
But I'd welcome any enlightenment on this.

UPDATE TBL_ARCHIVE a

Please post the actual query you are using and the actual complete error message you are getting (everything about the error that is displayed).^^
That is NOT a valid query?
How else would you have an UPDATE statement created to set the value of a column in table A to the value of a (in this case, same named) column in table B?
And keep them in order to update the records appropriately?
I'll append the create statements momentarily.

Doubt in UPDATE Statement

Hi,
I need to update all values in 2 columns (Net_Quantity) and (Net_Amount) based on join condition with the another table in plsql block.
Query which i tried
UPDATE TFS_FRCST_TOOL_LINES SET NET_ORDERS_QTY=l_net_orders_qty and NET_AMOUNT=l_net_amount
WHERE TFS_FRCST_TOOL_HDRS.HEADER_ID =TFS_FRCST_TOOL_LINES.HEADER_ID;
It not updating, returns error like command not properly ended.
Can any one please give idea to solve this.
Regards
Ajan

Dave is right. The first thing that struck was 'and' and I had pointed it to the user who posted this.
To Ajan --> You can try either of the options below,
UPDATE TFS_FRCST_TOOL_LINES
SET
NET_ORDERS_QTY=l_net_orders_qty,
NET_AMOUNT=l_net_amount
WHERE
TFS_FRCST_TOOL_LINES.HEADER_ID IN (SELECT TFS_FRCST_TOOL_HDRS.HEADER_ID FROM TFS_FRCST_TOOL_HDRS) ;
UPDATE (select NET_ORDERS_QTY, NET_AMOUNT
from TFS_FRCST_TOOL_LINES,TFS_FRCST_TOOL_HDRS

Function call in update statement

Hi,
I have an update statement as follows
update
tableA
set
some_Ind = 0
where
cond1=val1
and some_Ind = 1
and f_test(param1, param2) ='Y'
If i have say total 5 rows in tableA and the some_Ind is set to 1 for 2 rows.
Will this update stmt, call the funtion for all 5 rows ? and then update only the rows matching the condition?
Because i am expecting this update stmt to call the function for only the 2 rows which has the some_Ind as set but i get the message printed out 5 times for 5 rows but it updates only 2 rows.
Since this function f_test is very complex, i need to call it for only those rows to be updated.
Please give your suggestions....thanx...

I just gave the test function to display the two parameters.
This function is displaying the messages for all the 5 rows and not for the 2 rows which match the condition.
CREATE OR REPLACE FUNCTION f_test1 (param1IN VARCHAR2,param2 IN VARCHAR2)
RETURN VARCHAR2 IS
retInd varchar2(1);
begin
dbms_output.put_line('param1: '||param1);
dbms_output.put_line(param2: '||param2);
retInd := 'Y';
DBMS_OUTPUT.PUT_LINE('Val of retInd:'||retInd);
RETURN retInd;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line('other exception ');
RETURN 'N';
END;

Join condition in an update statement
