Nulls in join...
I have an application which I need to modify to support an additional class of product.
Specifically the new products have the same structure as the old ones, except they have one variant for each region.
The obvious thing to do is add an extra field in the key.
So
PRODUCT_CODE
-->
PRODUCT_CODE, REGION
where region may be null to accomodate the older product.
The problem is I know (believe) that
REGION = REGION is false when both are null.
Can I set something that says, treat NULL = NULL as true?
Or is there a better way of doing this? (I guess I could have a 'virtual region' 'THEWORLD' and have all the old ones in there?
Iain
You are correct, NULL will never equal NULL. There is no setting in Oracle to change this behavior, Oracle will always be consistent about its treatment of NULL values.
Without knowing more, having a 'WORLDWIDE' region for the existing products would seem like the simplest approach. There may be some benefit to breaking out a separate region-availability table and placing the constraint on that table.

Multiple rows Converge to Single row and join
Hi Folks,
I am facing a tricky challenge to join a table with multiple rows and converge into a single row (based on ID, period) and join with another table to get a single row. Let me explain.
Table 1: DTL_TABLE (id, period, course, names, title, type)
1 2010 mat john null null
1 2010 mat jim null null
1 2010 cam null officer null
1 2010 cam null Prof null
1 2010 phy null null Inclass
1 2010 phy null null Online
Join with
Table 2: ID_TABLE(id, period, Loc, Dept, Code)
1 2010 nj 101 CC.
Output format (id, period, course, names, title, type, Loc, Dept, Code)
result : 1 2010 mat,cam,phy john,jim officer,prof inclass,online nj 101 CC
I have created all the DDLs and DMLs if that help. Kindly let me know if a Join SQL query is possible.
Thank you,

Left joins on multi-million rows
i have a simple query doing left joining on several tables, upward of 7 tables. each table has several hundred million rows.
tblA is 1:M tblB and tblB is 1:M tblC and so on.
how to tune a query liked that?
sample query is
select distinct
a.col,b.col,c.col
from tblA a left join tblB b
on a.id=b.id
and a.col is not null
left join tblC
on b.id=c.id

What we were asking you is to post data we can work with rightaway, so CREATE TABLE statement, and INSERT INTO statement. So: not output, but statements...
Since I'm in a good mood (we're in the semi finals ;) ), here's an example of how you should post your data:
create table a1 as
select 1 quest_code, 'Fibrostenotic' quest_desc from dual union
select 2, 'Inflammatory' from dual union
select 3, 'Int Penetrating/Perforating' from dual union
select 4, 'Perianal Perforating Disease' from dual union
select 5, 'Uc Like' from dual union
select 6, 'Flare Of Disease' from dual union
select 7, 'Immunosuppressive Tx' from dual union
select 8, 'Iv Therapy' from dual union
select 9, 'Stool Consistency' from dual union
select 10, 'Urgency' from dual union
select 11, 'Stool Frequency' from dual union
select 12, 'Bleeding' from dual union
select 13, 'Adb Pain' from dual union
select 14, 'Fever/Chills' from dual union
select 15, 'Fistula' from dual union
select 16, 'Obstructive Sx' from dual union
select 17, 'Extraintestinal Sx' from dual union
select 18, 'Steroid Dependent' from dual union
select 19, 'Sibo' from dual union
select 20, 'Osteoporosis' from dual union
select 21, 'Osteopenia' from dual union
select 22, 'Growth' from dual union
select 23, 'Other' from dual;
create table a2 as
select 1 quest_code, 'U' quest_response, 88 user_id from dual union
select 2, 'U', 88 from dual union
select 3, 'U', 88 from dual union
select 4, 'U', 88 from dual union
select 5, 'U', 88 from dual;
create table a3 as
select 'testuserb' user_name, 88 user_id from dual;Posted like that, we can copy+paste and try to help you rightaway instead of waisting time formatting, putting quotes right etc. etc.
Also use the {noformat}{noformat} tag when you post an example.
That way it will stay formatted and indented.
So, when you type: {noformat}select *
from dual;{noformat}
it will appear as: select *
from dual;when you post it.
Finally, perhaps you could try something like this:SQL> select a1.quest_desc
2 , a2.quest_response
3 , case
4 when (select a3.user_id
5 from a3
6 where a3.user_id = a2.user_id) is not null
7 then (select a3.user_id
8 from a3
9 where a3.user_id = a2.user_id)
10 else (select a3.user_id
11 from a3
12 where a3.user_name = 'testuserb')
13 end user_id
14 from a1
15 , a2
16 where a1.quest_code = a2.quest_code(+);
QUEST_DESC Q USER_ID

Need sql query to find out Joins attached with folders in Discoverer
Hi,
Can anyone let me know the sql query which can be used to identify the joins which are attached to the folders.
Actually we have to identify all the joins conditions from folders those are migrated from one instance to others.
Thanks

You'll have to use the syntax:
FROM PC2KAUDIT,AUDITDETAIL
WHERE
... (other where clause)
AND
PC2KAUDIT.AUDITID = AUDITDETAIL.AUDITID (+)
This will do basically the same thing. Unfortunately there is no common syntax, unless oyu have a fancy ODBC driver, which might do this translation for you.

Joins And For all Enteries in Select Statement
Could you please tell me when there is a high amount of data which is being handled in the table, does the use of INNER JOINS and FOR ALL ENTERIES in SELECT Statement decreases the system performance? ?
Can you also let me know where can i get some tips regarding do's and dont's for ABAP Programming, I want to increase my system performance.
Currently the programs which are being used are taking a lot of time for execution...
Its very URGENT!Hai Jyotsna
Go through the following Tips for improving Performence
For all entries
The for all entries creates a where clause, where all the entries in the driver table are combined with OR. If the number of entries in the driver table is larger than rsdb/max_blocking_factor, several similar SQL statements are executed to limit the length of the WHERE clause.
The plus
Large amount of data
Mixing processing and reading of data
Fast internal reprocessing of data
Fast
The Minus
Difficult to program/understand
Memory could be critical (use FREE or PACKAGE size)
Some steps that might make FOR ALL ENTRIES more efficient:
Removing duplicates from the driver table
Sorting the driver table
If possible, convert the data in the driver table to ranges so a BETWEEN statement is used instead of and OR statement:
FOR ALL ENTRIES IN i_tab
WHERE mykey >= i_tab-low and
mykey <= i_tab-high.
Nested selects
The plus:
Small amount of data
Mixing processing and reading of data
Easy to code - and understand
The minus:
Large amount of data
when mixed processing isnt needed
Performance killer no. 1
Select using JOINS
The plus
Very large amount of data
Similar to Nested selects - when the accesses are planned by the programmer
In some cases the fastest
Not so memory critical
The minus
Very difficult to program/understand
Mixing processing and reading of data not possible

Optimizing the load of the database
Using table buffering
Using buffered tables improves the performance considerably. Note that in some cases a statement can not be used with a buffered table, so when using these statements the buffer will be bypassed. These statements are:
Select DISTINCT
ORDER BY / GROUP BY / HAVING clause
Any WHERE clause that contains a sub query or IS NULL expression
JOIN s
A SELECT... FOR UPDATE
If you wan t to explicitly bypass the buffer, use the BYPASS BUFFER addition to the SELECT clause.
Use the ABAP SORT Clause Instead of ORDER BY
The ORDER BY clause is executed on the database server while the ABAP SORT statement is executed on the application server. The database server will usually be the bottleneck, so sometimes it is better to move the sort from the database server to the application server.
If you are not sorting by the primary key ( E.g. using the ORDER BY PRIMARY key statement) but are sorting by another key, it could be better to use the ABAP SORT statement to sort the data in an internal table. Note however that for very large result sets it might not be a feasible solution and you would want to let the database server sort it.
Avoid the SELECT DISTINCT Statement
As with the ORDER BY clause it could be better to avoid using SELECT DISTINCT, if some of the fields are not part of an index. Instead use ABAP SORT + DELETE ADJACENT DUPLICATES on an internal table, to delete duplicate rows.

Nested Left Outer Join : Data Set
Hi All
I am bit confused about data set used by Nested Left outer join.
Can anyone help me.
Here is sample data:
Tables (Name, 3 Column each, total rows and matched rows if any):
Table 1
A B C
Total 20 Rows
Table 2
A D E
Total 50 Rows and 10 Matching on 2.A = 1.A
Table 3
D M N
Total 15 Rows and 15 Matching on 3.D = 2.D
Table 4
M X Y
Total 20 Rows and 10 Matching on 4.M = 3.M
Sql
select *
From Table 1
Left Outer Join on Table 2 on
2.A = 1.A
-- Data set 1 will contain 20 Rows (10 matching and 10 non matching)
Left Outer Join on Table 3 on
3.D = 2.D
-- What will be data set? 20 Rows of Data set 1 or 15 Matching Rows?
Left Outer Join on Table 4 on
4.M = 3.M
-- What will be data set? X Rows of Data set 2 or 10 Matching Rows?
Please have a look and clear my understanding.SeshuGiri wrote:
I have two tables defined (below). Emp table has data and there is no data in Emp_Type table yet! Right now it is empty.
I want to write a query that returns data from both the tables even though there is no data in Emp_type table. I am using left outer join but it returning nothing. Anyone can help?
select *
from emp e
left outer join emp_Type t
on e.empid = t.empid
WHERE t.type_id = 1
and t.end_date is null;
The join is including all rows from emp, just like you want.
The WHERE clause is discarding all of those rows. Since all the columns from emp_type (alias t) are NULL, the condition "t.type_id = 1" in the WHERE clause is never true.
Perhaps you meant to include all those conditions in the join conditions, like this:
select *
from emp e
left outer join emp_Type t
on e.empid = t.empid
and t.type_id = 1
and t.end_date is null;Edited by: Frank Kulash on Jan 30, 2012 3:56 PM -
WITH table1 AS
SELECT 123 prodid, 111 cid, 'BBB' bid, '563C' fid FROM dual UNION ALL

table2 AS
SELECT NULL cid, 'BBB' bid, NULL fid FROM dual UNION ALL
SELECT 222 cid, 'ccc' bid, '663C' did FROM dual UNION all
SELECT NULL cid, null bid, '563C' fid FROM dual UNION all
SELECT 22 cid, 'BBB' bid, NULL FROM dual
)what i want to do is to join table2 to table1 on the following logic
-- look at cid, if cid is not null then join with cid to table1
-- if cid is null then look at bid and see if it has value. if it does then join wit table2 bid to table1 bid
-- if bid is null, then look at fid and join the two table on fid
so the output should be something like this
prodid cid bid fid
======= ===== ===== =====
123 null BBB NULL
234 222 ccc 663c
123 null NULL 563c
567 22 BBB null
can someone help write a query that will join table2 to table1 and product the above output ?

thanks for the reply but is there a cleaner/easier way than doing the decode in where clause.
i am afraid this can hurt performance as table grows.
if you know a simpler way without using too many decode , please let me know. thanksI'm not sure why you think DECODE won't scale. When you talk about "as table grows", do you mean that you will be adding more and more id columns? If so, then you might find CASE to be cleaner and easier:
SELECT t1.prodid, t2.cid, t2.bid, t2.fid
FROM table1 t1
JOIN table2 t2 ON CASE
WHEN t2.cid = t1.cid THEN 'YES'
WHEN t2.cid IS NOT NULL THEN 'NO'
WHEN t2.bid = t1.bid THEN 'YES'
WHEN t2.bid IS NOT NULL THEN 'NO'
WHEN t2.fid = t1.fid THEN 'YES'
END = 'YES'
;Dimak showed how to do the job without any DECODE (or CASE). However, UNION is inefficient, and not necessary in this case:
SELECT t1.prodid, t2.cid, t2.bid, t2.fid
FROM table1 t1
JOIN table2 t2 ON t1.cid = t2.cid
OR ( t2.cid IS NULL
AND t1.bid = t2.bid
OR ( NVL (t2.bid, t2.cid) IS NULL
AND t1.fid = t2.fid

Problem with setting oracle type parameter in viewobject query
Hi There,
I am facing a problem with JDev1013. I have a view that has JDBC positional parameters that are supposed to be in parameters for function like:
SELECT x.day, x.special_exact_period_only
FROM (
SELECT x.day, x.special_exact_period_only
FROM (
SELECT
x.day,
rb.special_exact_period_only

TRUNC(SYSDATE + 365 * 2),
NULL
) x
JOIN resourcebase rb USING (rentabilitymanager_id)

x.day,
rb.special_exact_period_only

we are setting the parameter in the views with the help of oracle.sql.ARRAY class like:

Approach to tune a query in short time
Hi All,
Oracle 10g I know this question is asked number of times and there are many good replies to them.
But I just want to know how to approach a completely new query ( like the task given to me to fine tume a query in 1 day when I dont have even the slightest idea about how to proceed) if the timeline is very stringent and by just looking at the explain plan, you have to take the decision.
I am just posting my query here and what I am looking for is some lead on how to identify the congetion point which is where this query takes long time ( in my case some 15 mins as reported to me)

TABLE ACCESS FULL Object owner=MARS Object name=FEED_INSTANCEThis part has the highest costs (this doesn't always mean it is slow). So this leads me to the WHERE clause where feed_group, feed_group_xref and feed_instance full are used. Maybe this can be improved, although the cardinality is not that high, so a full table can be the best. So the question is can indexes help here?
Furthermore there is the full table scan on POSITION:
TABLE ACCESS FULL Object owner=MARS Object name=POSITION Cost=13995 Cardinality=3854299 Bytes=150317661This looks also a large tabel (3 million + records), so is it possible to get this part smaller?
