Help needed to optimize the query

Help needed to optimize the query:
The requirement is to select the record with max eff_date from HIST_TBL and that max eff_date should be > = '01-Jan-2007'.
This is having high cost and taking around 15mins to execute.
Can anyone help to fine-tune this??
   SELECT c.H_SEC,
                c.S_PAID,
                c.H_PAID,
                table_c.EFF_DATE
   FROM    MTCH_TBL c
                LEFT OUTER JOIN
                   (SELECT b.SEC_ALIAS,
                           b.EFF_DATE,
                           b.INSTANCE
                      FROM HIST_TBL b
                     WHERE b.EFF_DATE =
                              (SELECT MAX (b2.EFF_DATE)
                                 FROM HIST_TBL b2
                                WHERE b.SEC_ALIAS = b2.SEC_ALIAS
                                      AND b.INSTANCE =
                                             b2.INSTANCE
                                      AND b2.EFF_DATE >= '01-Jan-2007')
                           OR b.EFF_DATE IS NULL) table_c
                ON table_c.SEC_ALIAS=c.H_SEC
                   AND table_c.INSTANCE = 100;

To start with, I would avoid scanning HIST_TBL twice.
Try this
select c.h_sec
     , c.s_paid
     , c.h_paid
     , table_c.eff_date
from mtch_tbl c
left
join (
          select sec_alias
               , eff_date
               , instance
            from (
                    select sec_alias
                         , eff_date
                         , instance
                         , max(eff_date) over(partition by sec_alias, instance) max_eff_date
                      from hist_tbl b
                     where eff_date >= to_date('01-jan-2007', 'dd-mon-yyyy')
                        or eff_date is null
           where eff_date = max_eff_date
              or eff_date is null
       ) table_c
    on table_c.sec_alias = c.h_sec
   and table_c.instance = 100;

Help need to create a query

I need to fetch records from a table. Please help me to create a query
The Tablename is Employee. It has the following records
Department Empname Gender
Finance Tom Male
Finance Rick Male
Finance Stacy Female
Corporate Tom Male
Corporate Rob Male
I want to select the value of the Gender field from the Employee table corresponding to a Department
If all the values in the Gender field are 'MALE' corresponding to 'finance' in the Department field, the value should be 'MALE'
If there is a value 'FEMALE', the gender corresponding to the Empname 'TOM' should be considered as the gender

Tables have rows - not records.
Your question is a basic SQL language question - which means you do not know the SQL language. This forum is not a classroom for teaching you the SQL language.
Use the following as the basic outline of how your SQL language statement need to look like for selecting the required from the table:
SELECT
<<sql projection goes here>>
FROM <<table name goes here>>
WHERE <<filter conditions go here>>
{code}
The SQL projection specifies the list of columns the SQL need to return to the caller.
The filter condition is basic predicates and AND and OR can be used for multiple predicates.
Go to http://tahiti.oracle.com and look for the +SQL Reference Guide+ for the Oracle version you are using. The +SELECT+ statement syntax is covered in detail and sample statements are provided.
And please do not expect this forum to be used as a classroom, or expect this forum to do your homework for a class.

This is the Query and the query takes some mins. to run in prod environment.
From the Query plan ,I am not able to get any idea for optimization.

Help needed in writing a query

Hi all,
Following is the structure of my table.
Data
Key Number
Id Number
Value varchar2(100)
activity_name varchar2(100)
Creation_Date Date
Eval_Point varchar2(100)
In the above table Id is the primary key.
The column eval_point holds only two types of entries 'activation' or 'completion'
The activity_name column holds the name of the activity.
The sample entries in the table are as follows
Key Value activity_name Creation_Date Id Eval_Point
260002 XXX assign_1 2007-09-21 16:58:41.920000 951 activation
260002     XXX assign_1 2007-09-21 16:58:43.392000 953     completion
260002     XXX assign_2 2007-09-21 16:59:03.732000 956     activation

260002     XXX assign_3 2007-09-21 16:59:24.421000     957     completion
i need to write a query which gives me data in the following format
value id start_date end_date
XXX YYY 2007-09-21 16:58:41.920000 2007-09-21 16:58:43.392000
where start_date is the creation date of the 'activation' and end_date is the creation_date of 'completion'.
Can somebody help?

Help needed in framing SQL query.

Hi,
I have table having following schema:
PRODUCT_ID         INT
DATE                   DATETIME
ITEMS_SOLD         INT
This table contains data for a week (sunday to saturday). I want to write an SQL query to get (filter out) PRODUCT_ID of products which has same no. of ITEMS_SOLD for all 7 days. Also for given PRODUCT_ID I need to find the longest period of successive days where the no. of ITEMS_SOLD is same for all days in this period. Eg.(PRODUCT_ID 23 was sold as following along the week in no. of units sold: 4,6,6,6,6,7,4 .So the longest period is *4 days* from Monday to Thursday.) The first condition is special case of second condition where no. of days is 7.
Any help to get the SQL query will be appreciated.
Thanks,
Akshay.

PRODUCT_ID      DATE           ITEMS_SOLD
1          10/10/2011     3
1          11/10/2011     3
1          12/10/2011     3
1          13/10/2011     3
1           16/10/2011     5
2          10/10/2011     4
2           11/10/2011     4
2          12/10/2011     4
2          13/10/2011     4
2           14/10/2011     4
2          15/10/2011     4
2          16/10/2011     4
Output:
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
1          3                4
2          4               7
Explanation of results:
The table to be queried contains data for 1 week: from 10/10/2011(Sunday) to 16/10/2011(Saturday). Now, product with PRODUCT_ID '1' was sold on dates 10,11,12,13,16. Out of these 5 days 3 units were sold on 4 successive days (from 10-13). So output should be like :
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
1          3               4
as longest period of successive days is 4 where same no. of units were sold i.e 3 units (other period is of 1 day on 16th ).
For PRODUCT_ID 2 we have only one period of 7 days where 4 units were sold each day. So we output :
PRODUCT_ID ITEMS_SOLD NO_OF_DAYS
2           4               7
Other case where same PRODUCT_ID have different units sold on each day should be ignored.
I hope that clarifies the problem more. Let me know in case I have missed out anything which should have been mentioned.

Ok so thats my test table, I want a query which will give me the sum of the field Amount grouping by Year but it should give me the sum of the month from July 06 till July 07. For Example if i put the Date Range from 2003 to 2006 then it should give me out put by group the year from july till next year jun.
It should look something like this
Year Amount
07-2005/06-2006 5000
07-2006/06-2007 2000
07-2007/06-2008 1200
Can i get a query which will group in the above manner???
Thanks & Regards

Help needed in tuning this query

This is the SQL i would like to tune for performace...
The table structure is given below.
The table has about 2 million rows.
From the second day onwards only around 10% of records will be between Load_Start_Time and Load_End_Time. Among these around 50% will have THAMES_URN_WITH_ROLE_SUFFIX as 'TP%'. At present there are unique and primary key indexes on THAMES_URN_WITH_ROLE_SUFFIX .
I'm sure that we need a b-tree index on STG_UPDATE_DATE_TIME as it is the column with good selectivity.
I'm primarily concerned about the substr, instr and reverese on THAMES_URN_WITH_ROLE_SUFFIX.
Also pls. let me know if the order of predicates is right.
Thanks in advance.

> If indexes don't help, is the only way to gain REAL
performance gain on this type of query is to
partition the table
If a Full Table Scan on a table takes "too long" (and
this is purely subjective - "too long" is different
for every problem) and indexes can't help, and we
need <100% of the rows, and if partitioning will give
us the performance we desire, is it OK do it ? Also
would STG_UPDATE_DATE_TIME be the best column to do a
index partion ?
For this type of query, partitioning on STG_UPDATE_DATE_TIME would be good.
However, partitioning is not done just for one query. It has to fit in your total design. For example, if you are also doing queries with a predicate like <column with a local unique index but not the partition key> = <constant>, it would have to visit all partitions instead of just one, and those queries would take much longer to execute. You can make the index global, but there all kind of maintenance issues with that. In short: be careful about partitioning and think it through first.
> But is it a good option to partition tables with
total no. of rows between 2 million and 5 million ? I
thought partitioning is better done for tables > 20
million.
Please throw some light on that.
Generally, partitioning is done on bigger tables, yes. But it is not about some specific number of rows. You partition a table when all forecasted use of the table is known, so you can make a good judgement which usages will benefit, which ones won't be affected and which ones are likely to suffer. When the benefits outweigh the disadvantages, you partition...
Above I had an example about queries that are going to suffer. Partitioning is beneficial for example when once in some period you'd have to delete A LOT of old rows. Or when you have some data warehousing queries that need like 10% of only the most recent data in a huge table.
The decision is yours.

Rob.

Help needed in getting a query

Hi,
I have two tables issues and comments. Issues is parent table and comments is a child table with issue_id as the foreign key. There are two columns in master table Creation_date and closed_date . As the name suggests they refer to issue creation and closing date. I have say 4 statuses in comments table. Say 'open',moreInfo','Closed','Reopen'. There is also update_time column for the comments_table. So whenver the status is updated date and time is captured. Also when a issue is closed the update_time is entered into closing_date of the issues table as well. Also when the issue is reopened that closing date of the issue will be set to null. I wanted a query to calculate the average time required in closing the issue which I got that from the issues table by doing '-' of closingdate and creation_date.
But now I want to calculate the average time spent on the issues without taking the time spent on the status moreinfo into consideration. Also the status can change at any point of time. THere is no sequence in status change.
I want a SQL query for the above scenario.
Thanks

I want a SQL query for the above scenario.Maybe you just need to add
comments.status != 'moreinfo' to your WHERE clause. Without more specific information about your daya and your requirements, I can't be sure.
As mentioned before, post your query.
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle you're using.

I am very new to JDeveloper. Curently i am tryin to execute an SQL query from the BPEL process, the output of the query is to be mapped to a variable field from a target xsd file. the query is fairly simple, like
SELECT emp
FROM emp_table
WHERE emp_id=123
The target field, namely "employee", is an element from the xsd file. I tried using Java embedding activity to connect to the db and execute the query through a piece of Java code, but couldn't find a way to assign the output of the query to the field. however lately i also discovered the Database Adapter services which helps me create a database connection, but still i am not sure as of how to handle and map the output of the query to the variable field.
Can somebody please help me in resolving the issue either through Java Embed activity or Database Adapter services??
Thanks in advance
Anjan

Help needed in mapping BI query output to use as input for BAPI

Hi,
After wrestling with it for quite some time I choose to ask yet another question here. I want to use the output of a BI query I use as input for a BAPI. I just can not get the mapping correctly:
The query delivers: 104908BA092F7501F5E1008000829000AC
I need: 104908BA092F7501F5E1008000829000AC
How can I lose the two first digits? Thanks in advance!
Best regards,
Jan

Nevermind. I found out myself. I am now using the statement MID(@GUID,2,32) in the connection.
