Performance Tunning - Connect By and Outer Join Used - Urgent

Hi,
I have written a query with the outer join and connect by prior since to establish the parent child relation ship.
All the tables having 2 lakhs record but the final result set is 20 thousand rows.
The query is taking 5 minutes to complete the execution. How could i improve the performance.
The query is
SELECT
'ABC' hrchy_id,
SUBSTR(c.abc_cd,1,1) ,
a.org_no bu_node_id,
SUBSTR(d.abc_cd,1,1) ,
a.prnt_org ,
level hrchy_lvl_nb,
a.eff_from_dt,
a.eff_to_dt,
FROM ((parent a INNER JOIN f_org b ON (a.org_no = b.org_no))
left join org c on ( (a.org_no = (c.abc_cd)))
) left join org d on ( (a.prnt_org = d.abc_cd)))
WHERE a.co_cd ='000'
START with a.prnt_org = '0'
CONNECT BY a.prnt_org = PRIOR a.org_no
ORDER SIBLINGS BY a.org_no;
Please suggest any idea or commands to improve the performance.
Thanks in advance.

Can you provide the structure of tree based SQL.
Thanks in advance.But you have it already :-)

Equi Join and Outer join using outer keyword

Hi,
First lets take the create statment for scott schema.
create table scott.emp_details(empno number, bonus_date date);

Insert Into Scott.Emp_Details Values(7654, To_Date('05-feb-2013'));
commit;lets also consider the basic scott.emp and scott.dept tables
Now I would like to equi join emp table deptno col with dept table deptno col and left outer join emp table hiredate with emp_details bonus_date and empno col in emp_details can be joined(Equi Join) with empno col of emp table if needed .The outer join has to be placed using the keyword (left/right)outer join
The select statement can have all the detials of emp table .The requirement may look weird but we have some such requirement.
Please suggest

It's best not to create your own tables in Oracle-supplied schemas, such as SCOTT. Use your own schema for your own tables.
lets also consider the basic scott.emp and scott.dept tablesI see; you're using the standard scott,emp and scott.dept tables, plus the emp_details table you posted above.
Now I would like to equi join emp table deptno col with dept table deptno col and left outer join emp table hiredate with emp_details bonus_date and empno col in emp_details can be joined(Equi Join) with empno col of emp table if needed .The outer join has to be placed using the keyword (left/right)outer join

JDBC and outer joins

What is the correct syntax for an outer join using JDBC. A statement such as the following is returned with an illegal char. error:
select x.value, y.value from x_table x, y_table y
where x.id = y.id(+);
I'm using oracle 8i and the thin client driver.
Thanks

where a.id = b.id and
a.match = b.match;
A and B are entities and I need to join with two columns. Can someone please tell me what I'm doing wrong.
Thanks!Generally you do these kind of mappings through the Entities. For example, you can have a OneToMany / ManyToOne mapping between the two entities. Check out the Toplink reference guide for some examples on how to do this:

Even if you are not using Toplink, this is the same for all persistence providers.

Left outer join using anyOfAllowingNone

Hi,
I'm trying to join two tables (tableA and tableB) with left outer join using anyOfAllowingNone (One to many relationship) and try to fetch the tableB data with some constraint on it.
But the sql generated out of the expression builder is not a proper left join, it actually forms a inner join, which brings only table A data which satisfies all the condition. Actually I want all of tableA data and for every record from tableA I want the data from TableB which matches the key from tableA to tableB and some condition applied on tableB data.
I guess I'm doing some thing wrong, I went through the document and sample but still its not getting me the right data.
Below is my expression builder:
exp = builder.get("tableA_K").equal(some value);
exp = exp.and(builder.get("effectiveIn").toChar("MM/dd/yyyy").lessThanEqual(date));
exp = exp.and(builder.get("effectiveOut").toChar("MM/dd/yyyy").greaterThanEqual(date));
exp1 = builder.anyOfAllowingNone("tableBCollectionAttribute").get("effectiveIn").toChar("MM/dd/yyyy").lessThanEqual(date);
exp1 = exp1.and(builder.anyOfAllowingNone("tableBCollectionAttribute").get("effectiveOut").toChar("MM/dd/yyyy").greaterThanEqual(date));
return exp.and(exp1);
Below is the sample query generated:
select distinct tableA.all data
where (((((tableA.key = 2219785)
and (to_char(tableA.EFFECTIVE_IN_S, 'MM/dd/yyyy') <= '03/27/2008'))
and (to_char(tableA.EFFECTIVE_OUT_S, 'MM/dd/yyyy') >= '03/27/2008'))
and ((to_char(tableB.EFFECTIVE_IN_S, 'MM/dd/yyyy') <= '03/27/2008')
and (to_char(tableB.EFFECTIVE_OUT_S, 'MM/dd/yyyy') >= '03/27/2008')))
and (tableB.key (+) = tableA.tableB_Key))
Any help is appreciated. Thanks

Output a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE LIKE SFLIGHT-FLDATE,
 CARRID LIKE SFLIGHT-CARRID,

WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
If there are columns with the same name in both tables, you must distinguish between them by prefixing the field descriptor with the table name or a table alias.
Note
In order to determine the result of a SELECT command where the FROM clause contains a join, the database system first creates a temporary table containing the lines that meet the ON condition. The WHERE condition is then applied to the temporary table. It does not matter in an inner join whether the condition is in the ON or WHEREclause. The following example returns the same solution as the previous one.

Note
Since not all of the database systems supported by SAP use the standard syntax for ON conditions, the syntax has been restricted. It only allows those joins that produce the same results on all of the supported database systems:
Only a table or view may appear to the right of the JOIN operator, not another join expression.
Only AND is possible in the ON condition as a logical operator.
Each comparison in the ON condition must contain a field from the right-hand table.
If an outer join occurs in the FROM clause, all the ON conditions must contain at least one "real" JOIN condition (a condition that contains a field from tabref1 amd a field from tabref2.
Note
In some cases, '*' may be specified in the SELECT clause, and an internal table or work area is entered into the INTO clause (instead of a list of fields). If so, the fields are written to the target area from left to right in the order in which the tables appear in the FROM clause, according to the structure of each table work area. There can then be gaps between table work areas if you use an Alignment Request. For this reason, you should define the target work area with reference to the types of the database tables, not simply by counting the total number of fields. For an example, see below:
Variant 3
... FROM tabref1 LEFT [OUTER] JOIN tabref2 ON cond
Effect
Selects the data from the transparent database tables and/or views specified in tabref1 and tabref2. tabref1 und tabref2 both have either the same form as in variant 1 or are themselves join expressions. The keyword OUTER can be omitted. The database tables or views specified in tabref1 and tabref2 must be recognized by the ABAP-Dictionary.
In order to determine the result of a SELECT command where the FROM clause contains a left outer join, the database system creates a temporary table containing the lines that meet the ON condition. The remaining fields from the left-hand table (tabref1) are then added to this table, and their corresponding fields from the right-hand table are filled with ZERO values. The system then applies the WHERE condition to the table.

How to implement SCD and outer join in OBIEE

Hi Experts,
1.How we can implement SCD1 and SCD2 in OBIEE.
2. How to implement outer join..? Can we implement outer join in physical layer.?
Regards
Frnds

1. Better to implement this as a part of data warehouse/ETL. If you insist there is explanation on how to work with SCD's in Administrator in some Oracle University Student Book, I think it's for Siebel Analytics version.
2. Implement outer joins using complex joins in BMM (type option). It's possible to implement in physical layer only in obiee views (new physical table/table type - select), otherwise not, you cannot specify outer join in the physical layer using complex joins.

Inner join and outer join

how to use inner join and outer join methods in abap. pls explain

you have to code them
Seriously, I suggest you take an ABAP class, it's out of the scope of this forum to tech you how to program joins.

Outer join, use in a query.

Hi forum!
I want to do a query among three tables keeping empties rows. Is this possible to do with an outer join?
Could anybody give me an example how to use it¿?
Thanks in advance and regards,
Mon

Yes you can use outer join for the same.
In an inner join, a line from the left-hand database table or join is only included in the selection if there is one or more lines in the right-hand database table that meet the ON condition <cond>. The left outer join, on the other hand, reads lines from the left-hand database table or join even if there is no corresponding line in the right-hand table.
SELECT ...
FROM <tab> LEFT [OUTER] JOIN <dbtab> [AS <alias>] ON <cond> <options>
<tab> and <dbtab> are subject to the same rules and conditions as in an inner join. The OUTER addition is optional. The tables are linked in the same way as the inner join with the one exception that all lines selected from <tab> are included in the final selection. If <dbtab> does not contain any lines that meet the condition <cond>, the system includes a single line in the selection whose columns from <dbtab> are filled with null values.
In the left outer join, more restrictions apply to the condition <cond> than in the inner join. In addition to the above restrictions:
EQ or = is the only permitted relational operator.
There must be at least one comparison between columns from <tab> and <dbtab>.
The WHERE clause may not contain any comparisons with columns from <dbtab>. All comparisons using columns from <dbtab> must appear in the condition <cond>.
For details and examples of outer join please have a look at below links.

Inner join and outer join in infosets

hi everyone,
i have a doubt in infosets...
when and why we use inner and outer joins(right outer join and left outer join) for infoset
please give a real time scenario........
Thanks in advance.
Bye.

Hello,
Inner join:
For example, the requirement is to show all sales documents where you have delivery exists. In this case, you join both sales ods and delivery ods in a infoset as inner join. This will match the record against the reference documents and pull only matched records.
Outer Join:
Suppose you want to pull all billing/invoice details along with their FI documents related data in a report. Assume that always there might be a situation that invoice exists but not posted to FI, however, you want to have all billing documents details either it has FI document or not. In this case, you link both Billing data and FI document data in a outer join. This will pull all invoices data either FI document exists or not. Other words, you want to show one side of data always but adding additional details from differenent source if data exists.
Hope, it clarifies your doubt. Let me know if any questions.
Thanks

Hi all ,
We found the solution for this issue .
We have installed the crypto library in global executable directory and any way it will replicate those binaries to individual application servers.
But the parameters are still looking for global executable directory for loading crypto library during time.
So all application servers are trying to load crypto library files from global "exe" instead of local directory, which was clustered .Sometimes during heavy network load it may cause some delays to load the libraries to individual application servers and in turn is causing the license key issues.
Note 982056 - The license key library has not been initialized yet..
SAP Recommend option for all SSF parameters should be instance profile parameters not in default parameters..This was mentioned in below note:
Note 662340 - SSF Encryption Using the SAPCryptolib --- .
But in our Environment SSF and SEC parameter were set in DEFAULT profile instead Instance profile.
Recommendations:
o ssf/ssfapi_lib = <Path and file name of SAPCRYPTOLIB>
o sec/libsapsecu = <Path and file name of SAPCRYPTOLIB>
This was mentioned in the below SAP HELP.

Connecting iMac and MacBook Pro using a non-Apple wireless router

I use a Belkin wireless router. Is there any way for me to connect iMac and MacBook Pro using the router to share files? I think I read somewhere that I need AirPort Extreme for this, but I'm not sure. Thank you.

Great resource from Dennis...file sharing, I.e. networking, is a function of the operating system settings and not the brand of router. Using Mac OS X 10.6 on both machines makes it really seamless. Following Dennis's kb article should make the two almost act like one machine.

Generic connectivity to Sybase and outer join problem

I have a need to query records from a Sybase database running on Linux
(32-bit) and am using Oracle 10.2.0.3 with generic connectivity (no
specific heterogeneous service/transparent gateway for Sybase on Linux, that I see). We have installed
an ODBC driver on the Oracle server and can query the Sybase database
without difficulty except for outer joins.
I have tried using both the Oracle syntax and the ANSI syntax. Both
return results that are consistent with using an inner join. The ANSI
query, run directly against the Sybase database returns the correct
data (of course, removing the database link syntax).
I was looking into the possibility of using dbms_hs_passthrough, but
it does not appear to be part of the generic connectivity.
Is there a better/right way of doing this? Aren't outer joins supported?
Thanks,
Vince

As a followup, I did get dbms_hs_passthrough working and am able to get the correct data back. However, I would like to leave this as a backup.
Aren't outer joins supported in the generic connectivity?

Workspace Manager 10.1.0.4 and Outer Joins

We experience the following Problem:
We have a schema containing several Tables, one of them includes a SDO_GEOMETRY column (some Tables are about 2 million rows in size). We have to use some outer - joins in our statements, unfortunately the database - model is a generic one.
The outer joins seem to work fine when the schema is not version - enabled, the performance is ok. As soon as we version - enable the schema, the explain plans for the statements with outer joins radically change, there are several "full table access" - paths for large tables (including the one with the geometry column).
Statistics are up to date (executed dbms_stats.gather_schema_stats() with cascade => true).
Any Ideas?

Rather long, sorry. As you can see, there are several TABLE ACCESS FULL - paths for large tables, causing a lot of user I/O.
I also tried to use method_opt => 'FOR ALL COLUMNS SIZE 20', unfortunately it dindn't really change the plan.
Have you got any ideas left?
thank you for your help, anything can take me further
regards,
Nothi
