Query tuning - update with join statement

Hi,
I have 2 tables (table1 and table 2) with following condition:
TABLE 1 - Need to selection a column say staus ! = 'C'
join emp_id and project_id of TABLE1 and TABLE2
From join I am selecting minimun and maximum of TABLE2.salary and updating TABLE3 respective column.
Now as per requirement I have to update required column on TABLE2.EMP_ID = TABLE3.EMP_ID
Following is the query I have written,
update TABLE3 T3
set (T3.MIN_salary, T3.MAX_salary) = (
select min(c.salary), max(c.salary)
from TABLE2 t2, TABLE1 t1
where t2.emp_id = t1.emp_id
and t2.project_id = t1.project_id
and t1.status != 'C'
and t2.emp_id = t3.emp_id)
The above query takes 7 min to update some 8 lakhs records. Can you please suggest some other optimized method to do so?
Thanks in advance
Sandeep

Updateable scrollable result sets with join statement

I am writing a generic GUI fronend for any database that has a JDBC2.0 driver available.
I have been using scrollable updateable result sets. These work well for individual tables but as soon as two tables are linked either implicitly or explicitly with a join statement the result set meta data isDefinitelyWriteable is set to false thus preventing the result set from being updated.
Assuming I am using the JDBC-ODBC driver with java sdk1.4.0 and MS Access (although I have used other databases and JDBCs I assume that the one mentioned will be a common combination and needs to work) is there any way of getting linked tables to be updateable with scollable result sets.
I am using scrollable result sets since this prevents the necessity of putting the data in a secondary data store.
I am able to link tables programmatically by requerying the linked table with a new where clause each time the cursor moves in the linked table but this seems rather wasteful. This method is not vey satisfactory when attempting to display data from more than one table which have more than one linked level (i.e. cascaded links).
Is there a simple solution to this problem or do I have to do a rewrite using an update statement instead of having an updateable result set. I assume this method would also require the result set to be reloaded after the update.
Any suggestions much appreciated.

I am trying to make the GUI as flexible as possible by constructing "views" which if necessary link tables on one field in each table. This is fine for two tables but when linking to several tables the information thats produced cannot be read easily because as it stands the information from each table is displayed on a separate tabbed page. This mechanism allows me to keep each record set for each table separate and updateable.
Since I could see that this was not very user friendly in the way that it displayed the data I decided to try and introduce a join on two or more tables and hence the introduction of the current problem.
I mentioned that the objective was to be flexible and therefore I also allow queries to be written by the user to facilitate for any shortfalls of the automatic query construction produced by using the "views" mechanism.
So the answer to your question is yes I do control the SQL selections with one mechanism but ultimately no I do not because I provide a fail safe which allows the user to enter arbitary SQL.
I only really want a solution for the controlled SQL construction mechanism where I create the link between two or more tables. As mentioned earlier these are linked on one field only but I wish to provide the option of displaying the result in a single table (tabbed page) rather than spread across multiple tabbed pages.

Query based on "NATURAL JOIN" statement of Oracle9i

I have created following 4 tables
create table CUST_MASTER
(CUST_NO NUMBER(3),CUST_NAME VARCHAR2(20),CUST_CITY VARCHAR2(20));
create table ITEM_MASTER
(ITEM_NO NUMBER(2),ITEM_NAME VARCHAR2(20),
PRICE NUMBER(4));
create table ORDER_HEADER
( ORDER_NO NUMBER(4), CUST_NO NUMBER(3));
create table ORDER_ITEMS
( ORDER_NO NUMBER(4), ITEM_NO NUMBER(2), QTY NUMBER(3));
Based on the above 4 table I have executed the following query.
select c.cust_no, c.cust_name, c.cust_city, oh.order_no, i.item_no, i.item_name, i.price, oi.qty
from cust_master c, item_master i, order_header oh, order_items oi
where c.cust_no = oh.cust_no and oh.order_no = oi.order_no and oi.item_no = i.item_no;
How should I build similar query in Oracle9i making use of "NATURAL JOIN" statement?

Hallo,
yes you are correct.
From SQL Reference
NATURAL JOIN The NATURAL keyword indicates that a natural join is being performed. A natural join is based on all columns in the two tables that have the same name. It selects rows from the two tables that have equal values in the relevant columns
Nothing about foreign keys.

select * from scott.emp natural join scott.dept

Oracle Syntax for Update with Join

Can anyone help with the Oracle Syntax on and update that includes a join?
This is what I've got:
Update
(SELECT a.DOCUMENT_NO
From DOCUMENT_CONTROL a, DOCNOTEST b
where a.DOCUMENT_NO = b.DOCUMENT_NO)
set a.PATH = NULL
Everything I try leads to another error message. With the current code I'm getting the error message: ORA-00971 a.path invalid identifier.
I am much more familiar with SQL Server (if you can't tell :) This is the way I would write the above in SQL Server.
UPDATE DOCUMENT_CONTROL
Set [Path] = ''
FROM DOCUMENT_CONTROL
INNER JOIN DOCNOTEST
ON DOCUMENT_CONTROL.DOCUMENT_NO=DOCNOTEST.DOCUMENT_NO
where DOCUMENT_CONTROL.DOCUMENT_NO=DOCNOTEST.DOCUMENT_NO
Does anyone have any advice for me? Thanks in advance

Alternate syntax since it seems you're not able to update the join...
update DOCUMENT_CONTROL a
set
   a.path = null
where a.path is not null
and exists
   select null
   from DOCNOTEST b
   where a.DOCUMENT_NO = b.DOCUMENT_NO
);

Update with join and group by

Hello All,
I'm trying to update several colums of a table from a inner join query.
First a retrieve the rows afected and the values that I need for the update (I call this subquery ED_Query).
It's important to note that this subquery has a group by and and having clause.
My first attemp (using the query that work in SQL Server query) fails:

The subquery (ED_Query) work fine in Oracle, so I suspect that the problems are when I mix it with the update clause.

I have 2 tables. I like to update one of them (ED_Update) with the data from the another one (ED_Query).
This example is equivalent:
create table ED_Query (id number,
     date01 date,
number01 number)
insert into ED_Query values (1, to_date('01/01/2013','DD/MM/YYYY'), 10);
insert into ED_Query values (2, to_date('01/01/2013','DD/MM/YYYY'), 20);
insert into ED_Query values (3, to_date('01/01/2013','DD/MM/YYYY'), 30);
insert into ED_Query values (4, to_date('02/01/2013','DD/MM/YYYY'), 40);
insert into ED_Query values (5, to_date('03/01/2013','DD/MM/YYYY'), 50);
create table ED_Update (date01 date,
          numberMax number,
          numberSum number)
insert into ED_Update values (to_date('01/01/2013','DD/MM/YYYY'), 0, 0);
insert into ED_Update values (to_date('02/01/2013','DD/MM/YYYY'), 0, 0);
insert into ED_Update values (to_date('03/01/2013','DD/MM/YYYY'), 0, 0);
The next update query fails with ORA-00933: SQL command not properly ended.
update ED_Update
set ED_Update.date01 = ED_Query.date01,
     ED_Update.numberMax = ED_Query.numberMax,
     ED_Update.numberSum = ED_Query.numberSum
inner join
     select date01, max (number01) as numberMax, sum(number01) as numberSum
     from ED_Query
     where date01 = TO_DATE('01/01/2013', 'DD/MM/YYYY')
     group by date01
) ED_Query
on ED_Update.date01 = ED_Query.date01
I think the problem is in the update clause because the next query work:
select * from
ED_Update
inner join
     select date01, max (number01) as numberMax, sum(number01) as numberSum
     from ED_Query
     where date01 = TO_DATE('01/01/2013', 'DD/MM/YYYY')
     group by date01
) ED_Query
on ED_Update.date01 = ED_Query.date01
Thank in advance.

Update with join

Hello Everybody
I have 3 tables in a maxdb 7.6 database
rbarbeitsplanpos key=rbarbeitsplanposid column gewichtung,...
rbaplposausf key=rbaplposausfid columns rbarbeitsplanposid,...
rbqspruefpos key=rbqspruefposid columns rbaplposausfid,gewichtung,...
Now i want to update gewichtung in rbqspruefpos with the value of gewichtung in the corresponding record in rbarbeitsplanpos.
The way to find the correct value is:
From rbqspruefpos with rbaplposausfid into rbaplposausf
From rbaplposausf with rbarbeitsplanposid to rbarbeitsplanpos
I found this hit:
A simple example of the power of including joins in an Update Statement:
Update Tbl1 set tbl1.field1=tbl2.field2*.10,
from Tbl1 join tbl2 on tbl1.PKfield=tbl2.tbl1FK
This will update all the joined rows in tbl1 to 10% of the values in tbl2.
I code:
update rbqspruefpos set gewichtung = rbarbeitsplanpos.gewichtung,
from rbqspruefpos
join rbaplposausf on rbqspruefpos.rbaplposausfid = rbaplposausf.rbaplposausfid
join rbarbeitsplanpos on rbarbeitsplanpos.rbarbeitsplanposid = rbaplposausf.rbarbeitsplanposid
General error;-5016 POS(73) Missing delimiter: =
This one works without errors:
update rbqspruefpos set gewichtung = (select rbarbeitsplanpos.gewichtung from rbarbeitsplanpos
join rbaplposausf on rbarbeitsplanpos.rbarbeitsplanposid = rbaplposausf.rbarbeitsplanposid
join rbqspruefpos on rbqspruefpos.rbaplposausfid = rbaplposausf.rbaplposausfid)
but all rbqspruefpos.gewichtung are filled with the same value?
The first value found in rbarbeitsplanpos.
Any help welcomed
Best regards
Albert

Looks like you're doing it wrong.
Subselects need to be enclosed in brackets.
See [Subquery (subquery)|http://maxdb.sap.com/doc/7_6/60/515f3eca2a11d2a97100a0c9449261/content.htm]
Only scalar subselects (these are the ones that by their very structure can only produce zero or one rows in the result set) can omit the brackets.
The database cannot know that there is only one value in this column - you may try and put a aggregation function round it.

Help with an update with join (works in access)

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..
can someone please help me translate this query to work on oracle?
Thanks!
-nikhil.

thanks for your reply. however, im a little confused . i want to update the table caxnode for a particular node_alias if the same table has the SAME node_alias defined as partition_Type=ldom
for eg..
my table is as follows
id node_alias host_id node_mode partition_type num_procs
1 abc abc virtual null 2
2 abc xyz logical LDOM 4
3 def def virtual null 2
4 def ppp logical LDOM 8
5 abc abc regular null 3
So those that are ldoms are marked ldom in partition_type, those that are not recognised as ldoms are marked null in partition_type. LDOM's are logical in node_mode, others are either virtual or regular in node_mode.
Now since there are some old entries that are marked regular/virtual and NULL but are actually LDOMs, I need to go through the table and mark those as LDOM's which have same node_alias marked as LDOM later on.
In the table above, abc is marked as LDOM in row 2, so row 1 and 5 should reflect that. the host id should change to host_id in row 2 because the same alias is defined as ldom in row 2..
Same with def.. host_id for def should change to host_id thats in row 4 because def is also defined as ldom in row 4..
The table should look like this
id alias host_id node_type num_procs
1 abc xyz LDOM 4
2 abc xyz LDOM 4
3 def ppp LDOM 8
4 def ppp LDOM 8
5 abc xyz LDOM 4

Problem with Join Statement

hay guys
             I have written a query in ABAP OO to join 2 tables and have output in different table.Here i want only selected fields in 3 table .I dont know why this query is giving erroe.Help needed.
TYPES : BEGIN OF ty_catsubcat,
          CATEGORYID type ZNCYID,
          DESCRIPTION_CAT TYPE ZNCYID,
          SUBCATID type ZNSBCYID,
          DESCRIPTION_SUBCAT type ZNSBDS,
          END OF ty_catsubcat.
DATA :   IT_CATSUBCAT TYPE TABLE OF ty_catsubcat.
Select ZNCYMS~CATEGORYID ZNCYMS~DESCRIPTION ZNSBCYMS~SUBCATID ZNSBCYMS~DESCRIPTION
         INTO (IT_CATSUBCAT-CATEGORYID,
                  IT_CATSUBCAT-DESCRIPTION_CAT,
                  IT_CATSUBCAT-SUBCATID,
                  IT_CATSUBCAT-DESCRIPTION_SUBCAT)
         FROM ZNCYMS INNER JOIN ZNSBCYMS
         ON   ZNCYMS~CATEGORYID = ZNSBCYMS~CATEGORYID
         order by ZNCYMS~CATEGORYID.
endselect.

A few issues..
Your table it_catsubcat does not have a header line, and you are trying to insert into the header area of the table which does not exist. Either declare a work area/header, or do a table fetch instead.
Select ZNCYMSCATEGORYID ZNCYMSDESCRIPTION ZNSBCYMSSUBCATID ZNSBCYMSDESCRIPTION
        <b> INTO CORRESPONDING FIELDS OF TABLE IT_CATSUBCAT</b>
         FROM ZNCYMS INNER JOIN ZNSBCYMS
         ON   ZNCYMSCATEGORYID = ZNSBCYMSCATEGORYID
         order by ZNCYMS~CATEGORYID.
If you use a work area to insert into, then you need to append the work area to your internal table.
data: IT_CATSUBCAT TYPE TABLE OF ty_catsubcat with header line.
Select ZNCYMSCATEGORYID ZNCYMSDESCRIPTION ZNSBCYMSSUBCATID ZNSBCYMSDESCRIPTION
         INTO (IT_CATSUBCAT-CATEGORYID,
                  IT_CATSUBCAT-DESCRIPTION_CAT,
                  IT_CATSUBCAT-SUBCATID,
                  IT_CATSUBCAT-DESCRIPTION_SUBCAT)
         FROM ZNCYMS INNER JOIN ZNSBCYMS
         ON   ZNCYMSCATEGORYID = ZNSBCYMSCATEGORYID
         order by ZNCYMS~CATEGORYID.
append it_catsubcat.
endselect.

Count of Rows Updated with prepared statement batch

I am using a batch of prepared statements for update operation. (pstmt.executeBatch())
Configuration I am using
WLS 6.1sp2 Connection pool - Oracle Thin driver - TX Datasource
DB - Oracle 8.1.7
The batch update works well i.e data gets updated and committed. BUT I am not
getting back the count of number of rows updated.
Is there any thing more required on WLS side ?
Thanks in Advance

The Oracle drivers do not return the updated row counts from batched updates.
Try running the attached program with the thin driver
java Batch oracle.jdbc.driver.OracleDriver jdbc:oracle:thin:@host:port:database user password
You will see that returns -2, which indicates that the number of rows updated is unknown.
This does meet the JDBC spec.

Please advise

The CBO has estimated that you have 2415K table1 rows where joining_date = 20090205. (By the way: is this really a number?!)
Is this estimate accurate?
Please add some more information:
- Which version do you use
- How long is "very long time"?
- How many does your query return

Update with case statement problem.

Hi,
I have this statement
update tab_tr set col_rate =
case
when col_ern_type in ('031','035','036') then (1.5 * col_rate)
when col_ern_type in ('041','045','046') then (2 * col_rate)
end;this statement updated some 2 million rows in the table tab_tr. But the total count of rows for col_ern_type in ('031','035','036', '041','045','046') yeild only around 222642 rows.
select count(*) from tab_tr where col_ern_type in ('031','035','036', '041','045','046'); --> 222642 rowswhat is the problem with the above update statement.
Thank you,

... I thought the case statement conditions are counted as the where condition. But ......A CASE expression just takes the place of some other expression, such as a literal, a function, or a column.
For example, which rows do you think this should update?
UPDATE tab_tr
SET     col_rate = 100;It would update all rows, of course.
How about this statement?
UPDATE tab_tr
SET     col_rate = column_x;Will it only change the rows where column_x are a certain value, or not NULL, or in any way depend on column_x? No, of course not. It will update all rows.
How about this statement?
UPDATE tab_tr
SET     col_rate = function_y (col_ern_type);Will it only change the rows where the fucntion returns a certain value? Will it depend on the value in col_ern_type? No, of course not. It calls the function for each row, and whatever the function returns (even if the function returns NULL), that's what goes into col_rate on each row.
A CASE expression is just something that you can substitute in place of any other expression, such as the literal 100, or the column column_x, or the function function_y in the statements above. Naturally, the value that gets put into col_rate will depend on what the CASE expression returns, but the behavior of the UPDATE statement as a whole will not.

Query report issue with Joins

HI Everyone,
I'm facing a issue with SQ02, where I need to link 2 table COVP and AFRU . Now that I have 2 feilds in COVP REFBN and AWORG which is or Char(10) feilds and I need to link this with tabl;e AFRU feilds RUECK and RMZHL which is of Num(10) and Num(4).
I cant use a join link between these 2 feilds as it says illegal join. Now I need to pull data by the input from COVP that of refbn and aworg.
Please let me know how to go about and implement this? Is there a way where I can use the code section and write code for this. I need to further add another table CATSDB from the output from AFRU.
Thanks & Best regards,
Raj

Hi Raj,
I had the same problem with other join, since the two fields are different it is not possible to use a join on them.
The only solution that occurred to me was to create an auxiliary table to map both fields with all possible values, like this:
| fild1 | field2 |
| 001 | 00001 |
| 002 | 00002 |
And a view with one of the tables together with this auxiliary one. Then the join would use this view...
I admit it isn't pretty, but it would work. However in the end I've decided to write a program instead of using a query to obtain our client's desired map.
best regards,
Edgar

Update with case statement

Hello,
I want to use case in update statement.
For example I have a table whose name is Item. There are 20 fields in this table. StockHoldType, Quantity and Amount are three of them.
I want to update quantity or amount fields according to stockholdtype fields value. If stockholdtype is 1 , I will update quantity field,
if stockholdtype field is 2 I will update amount field.
How can I do this?

upadte table_name
set Quantity = decode(stockholdtype,1,+new_value+,quantity),
amount = decode(stockholdtype,2,+new_value+,amount)
where stockholdtype in (1,2)

Update with join/subquery

I have 2 tables
tblA(aID, aSeq, aname, aLname)
tblB(bSeq, bname, bLname)
I need to update table tblA to set aSeq where the name and Lname match with tblB. Something like
update zA A
set A.aSeq =
select B.bSeq
from zB B
where UPPER(B.bname) = UPPER(A.aname)
and UPPER(B.blname) = UPPER(A.alname)
What am I doing wrong? Why do I get the error - ORA-01427: single-row subquery returns more than one row

based on above scenario (tblA => proposal tblB => personnel)
select rp.prop_id || '| ' || UPPER(rp.prodir_fn) || '| ' || UPPER(rp.prodir_ln)
from proposal rp
where exists(
select p.piid ---------------------------------------------------get matching names from personnel

SQL Server updating with join issue

I'm currently running the following script:SQLUPDATE [PO_RECVR_HIST]SET [PO_RECVR_HIST].[REF] = ( CASE -- Place MUD or HOCKEY in receiver header reference fields WHEN coalesce([IM_ITEM].[ATTR_COD_1], '') = 'MUD' THEN 'MUD' WHEN coalesce([IM_ITEM].[ATTR_COD_1], '') = 'HOCKEY' THEN 'HOCKEY' ELSE coalesce([PO_RECVR_HIST].[REF], [PO_RECVR_HIST].[REF]) END )FROM [PO_RECVR_HIST] LEFT JOIN[PO_RECVR_HIST_LIN]ON -- Acquire all the line information for each receiver header[PO_RECVR_HIST].[RECVR_NO] = [PO_RECVR_HIST_LIN].[RECVR_NO]LEFT JOIN[IM_ITEM] ON -- Acquire all the item information (specifically attribute code 1) for each line item on the receiver[PO_RECVR_HIST_LIN].[ITEM_NO] = [IM_ITEM].[ITEM_NO]I'm trying to run this script on the PO_RECVR_HIST...
This topic first appeared in the Spiceworks Community

1) First Reboot your server and try again for the installation.
2) If first fail again than Take a backup of Registry first for safe side and then delete the entries of SQL server 2012 if found take a reboot again and try to install again.
One more thing if installation created any file then move/Delete that also before installation.
