SQL & PL/SQL :: Update Query Using Join
Jun 26, 2012How to update single table column using join query
Example:
Update table1 t1,table2 t2
set t1.column2 = 'Y'
where t1.column1 = t2.column1
How to update single table column using join query
Example:
Update table1 t1,table2 t2
set t1.column2 = 'Y'
where t1.column1 = t2.column1
I've seen this example numerous places, and tried to implement it, but I keep getting an "invalid identifier" error message, despite the fact that I've got the table and column specifically identified.For instance, my query reads like:
UPDATE tbl1
SET tbl1.EMPID =
(SELECT tbl2.EMPIDA FROM tbl2
WHERE LOWER(tbl1.EMAILCOL) = LOWER(tbl2.EMAILCOL2)
)
WHERE tbl2.EMPIDA IN ('Z1O435','S8M4722','M0D5156')
AND EXISTS
(SELECT tbl2.EMPIDA
FROM tbl2
WHERE tbl1.EMAILCOL= tbl2.EMAILCOL2 );
But I'll keep getting flagged at the tbl2.EMPIDA column reference. I have not tried this in SQL Plus, just in TOAD, but it seems to repeatedly fail.I have had to dump records to standalone Access tables and link back to perform the updates.
I have two tables. By joining these two tables, I need to update a field in table1.
UPDATE table1
SET table1.FLAG = 'Fixed'
where table2.lastname = table1.lastname
and table2.status in ('fulltime','parttime')
I keep getting error 'table1.lastname' is invalid identifier.
I can't understand the error message. I made sure that the fields exist.
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.
im trying to update a column in the employee table with the value "YES". Im getting an error message saying im missing a SET statement from this code below:
update e
SET e.review='YES'
from employee
inner join rentals r
on e.employee_id=r.employee_id
inner join job j
on e.job_id=j.job_id
where r.plate ='FY06WNT'
and j.function !='MANAGER'
and j.function !='PRESIDENT';
drop table dev10 purge
/
drop table dev11 purge
/
drop table dev12 purge
/
create table dev10 as
select rownum c1, sys.dbms_random.string('U', 6) c2, trunc(sys.dbms_random.value(1, 7)) c3
from dual connect by rownum < 8
/
[Code]...
Now, Let us assume that, the record is
AAAAAA BBBBBB CCCCCC
DDDDDD EEEEEE FFFFFF
...
..
.
Now, we want dev12.c2 is 'FFFFFF' if dev11.c2 is 'BBBBBB', if we want to get this:
AAAAAA BBBBBB FFFFFF
DDDDDD EEEEEE FFFFFF
...
..
.
We can make this for SqlServer by coding:
UPDATE dev10
SET c3 = dev12.c1 FROM dev10 INNER JOIN dev11 ON dev11.c3 = dev10.c1 CROSS JOIN dev12
WHERE (dev11.c2 LIKE 'BBBBBB')
AND (dev12.c2 LIKE 'FFFFFF')
/
but, Oracle, what should we do new?
This is my working query in ms access...
UPDATE Caxnode AS A INNER JOIN Caxnode AS B ON A.node_alias = B.node_alias SET A.partition_Type = 'LDOM', A.node_mode = 'LOGICAL', A.host_id = b.host_id, A.num_of_proc = b.num_of_proc WHERE (((A.node_mode)='virtual' Or (A.node_mode)='regular') AND ((B.partition_Type)='LDOM'));
This doesn't work in oracle, I googled and read that update doesnt work with inner join in oracle..
translate this query to work on oracle?
I want to use join condition in update syntax.Like the following way but it doesnot work.how to fix it.
update tab_1 a
set a.qty = b.sell_qty
from tab_2 b
where a.nbr=b.nbr
I am trying to write an Update that really frustrates me because it won't work for one reason or another.The situation is that I have two tables for customer information, t1 with the names of the customer and t2 with the address.These two can be joined via a client_id.
Now I have a third table t3 with the name and address of potential customers. I want to find out if some of them are already known to me so that I can update the client_id from table t1 or t2 into t3.
I have to join firstname, lastname from t3 to firstname, lastname from t1 and street, zip, city from t3 to street, zip, city from t2 and client_id from t1 to t2. Additional there is the problem that there can be more than one result so I have to update one of the found client_ids per name/address into t3.I am no expert to PL/SQL, I just know what SQL works in Access and that is:
UPDATE (t3 INNER JOIN t1
ON (t3.firstname= t1.firstname) AND (t3.lastname = t1.lastname)) INNER JOIN t2
ON (t3.city = t2.city) AND (t3.zip = t2.zip) AND (t3.street = t2.street) AND (t1.client_id = t2.client_id)
SET t3.client_id = t1.client_id;
I Require to Update the Data in Join Condition. When Run the Query the Error display as ORA-00933: SQL Command Not Properly Ended.
Query:
Update a set a.Dr_Re = Nvl(b.Dr_Amt,0),
a.Cr_Re = Nvl(b.Cr_Amt,0)

Am trying to write code for sollowing scenario:
Have 3 tables
table1 (campaignid,promoflag)

I am to update table 1 promoflag with value from promoflag in table3
Update table1
set promoflag = table3.promoflag
I would like to make sure only appropriate record is updated therefore want to use where clause condition but the primary key for table1 and table3 are different, the only link can be found on table2.
I want to use condition where table1.campaignid=table2.campaignid and table2.projectid=table1.projectid
Have used the following without success:

Throught this query, I get a extra record with null value in the Sub_name and Sub_Cno.update this query using a self join.
I have an attendance table in which we have empno, time_in, time_out..etc.
I want to create a matrix report that should shows all dates of any specific required month in columns and present empno in rows and time_in in cells.
I did it with using a temporary table by filling all the required dates and outer join with attendance table, it works fine, but it takes so long, is there any other better fast way to do it?
I have the following 2 tables.
A) Docversion
CREATE TABLE DOCVERSION
("OBJECT_ID" VARCHAR2(250 BYTE),
"OBJECT_CLASS_ID" VARCHAR2(250 BYTE),
);
[Code]..
Join column : object_id and parent_id.
The object id in docversion will have multiple values for element value in listofstring table.
ordinal value represents teh sequence of element value
Eg:
data for docversion:
1 23
2 34
data for LISTOFSTRING:
1 11 0 100
1 11 1 109
1 11 2 119
2 22 0 A
2 22 1 B
ouptut:
I want the output as follows
docversion.objectid,listofstring.elementvalue
1 100,109,119
2 A,B
I have come across a join in a query which has the (+) symbol at the end of it.
View 3 Replies View RelatedI have been told to create a query which should give out the same output as the UI of an exception management application . However , many referenced tables have one to many relationship . I created a query using a function which was giving the required output . But the performance of the query was not good as for each row . Is there a method to create a select using joins to show one to many relationship in a table .
View 4 Replies View RelatedIn my Oracle 9i Schema, I have two tables:
Table One
pocOne pocTwo
2 3
2 4
1 2
Table Two
TableTwoId Name
1 Jones
2 Smith
3 Edwards
4 Camden
My SQL to fetch all records with Smith works great:
select Name from TableTwo
Inner Join TableOne
on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo)
where Name = 'Smith'
Now I need to create an alias for the Name field. Here is my attempt:
select myAliasName from TableTwo
Inner Join TableOne
on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo),
(select Name as myAliasName from TableTwo)
where myAliasName = 'Smith'
This attempt pulls up all the records instead of just Smith records. How I can create an alias for the Name field in my above query?

In SQL, almost all the thing which are possible with join is possible with sub-query also and vice-a-versa.
So when should I use sub-query and when should I go for join?

I saw a strange plan for one query in TESTING DB today. Although 2 tables are involved i dont see any join , NL/HJ/SMJ !! i am not facing any performance issue but curious to know what type of optimization oracle is doing here.
Query text and plan :
SELECT FIRST_NAME
FROM CAMPA.TABLE_A
WHERE NAME_ID =
(SELECT NAME_ID
FROM CAMPA.TABLE_B
WHERE ban=:b1);

must generate a Cartesian join, but I do not know why it happens. dt.debtorkey, cl.clientkey, inv.invoicekey, ag.agingkey are primary keys of each table. The problem is: I got same tuple for 8 times.
select dt.debtorkey, cl.clientkey, inv.invoicekey, ag.agingkey, dt.DebtorNo, dt.Name as "debtor Name", dt.State, cl.ClientNo, cl.Name as "Client Name", inv.InvNo, inv.PurchOrd, inv.Amt,
to_char(inv.InvDate, 'MM-DD-YY') invoice_date, to_char(ag.DateLastBuy, 'MM-DD-YY') aging_lastbuy, to_char(ag.DateLastPmt, 'MM-DD-YY') aging_lastpmt

The full statement is:
SELECT v.key$ FROM VERSION_TABLE v, DOCUMENT_TABLE d, CLASS_TABLE z WHERE
v.documentKey = d.key$ AND
d.classKey = z.key$ AND
z.key$ IN (SELECT zz.key$ FROM CLASS_TABLE zz
START WITH zz.name = 'esDTTemplate'
CONNECT BY PRIOR zz.key$ = zz.parentKey) AND
v.ESGROUP = 'SearchOperatorsMapping' ORDER BY d.name
Now I noticed that the subquery is never used to seed the join: indexes - if any - are used. Otherwise a full table scan is performed.In the example - if ESGROUP is indexed, then it's chosen to start the join evaluation. If not, a full table scan is performed.Is there any way to suggest to the optimizer to use the subquery in case there are no indexes - as a fallback ?
In the above example where VERSION_TABLE contains nearly two million records, the no index solution takes 60 secs. vs. less than 1 sec. in the index case.Wrapping the hierarchical query in a inline view leads to same result.
PS: the execution plan (without index) is:
-------------------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time
-------------------------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | | | 9 (100)| |
