SQL to retrieve the records in subset

Dear Friends,
I have requirement to fetch 5 Million records from Oracle db and display using JAVA and JSP. Each record is 1 KB size.
The database table is online table used to store the transaction details, the rows will keep increasing. I am not allowed to use stored procedures also.
1) Fetching 5 Million record and displaying in 1 attempt is not feasible as JDBC has limitation and also the User has to wait too long to see the data.
I am thinking of processing the records in subset, for example.. Display first 10000 records then if the users wants next 10000 records fetch and display the next 10000 record.
Are there any other best practices to implement the above requirement.
I am not sure how to write the above SQL query? Can anyone please help me write the above SQL query?
I dont this I can use romnum as the rows are increasing.
Below is my Table structure and SQL query which returns 5 Million record
CREATE TABLE MESSAGE_LOG
SOURCE VARCHAR2(25 BYTE),
TARGET VARCHAR2(25 BYTE),
ENGINE VARCHAR2(100 BYTE),
PROCESS VARCHAR2(400 BYTE),
SERVICE VARCHAR2(100 BYTE),
LOGTIMESTAMP TIMESTAMP(6)
SELECT * FROM MESSAGE_LOG WHERE LOGTIMESTAMP BETWEEN TO_DATE('20-MAY-2010 01:00','DD-MON-YYYY HH24:MI') AND TO_DATE('20-MAY-2010 23:00','DD-MON-YYYY HH24:MI')
Thanks in advance,
Bob

I am not allowed to use stored procedures also.Why, is there a business requirement that says the application should be as difficult to develop as possible, be unreliable and hard to maintain when things go wrong?

Try this link and come back when you have got to the 5,000,000 result of the 6,730,000 that are estimated to be there
http://www.google.com/#hl=en&q=oracle+procedure
Or you could list every thread in the forum and multiply the time it takes you to get to the last by 50.
I am thinking of processing the records in subset, for example.. Display first 10000 records then if the users wants next 10000 records fetch and display the next 10000 record.Try looking at 10,000 threads on this forum or 10,000 results from Google and see how long that takes.
Are there any other best practices to implement the above requirement.Yes, don't return more information than anyone could possibly find useful

Retrieve the records based on date where date is not stored

Hi,
I have one table in Oracle.
I want to retrieve the records which are added or modified after a particular date & time.(but the table does not contain any column for date & time )
For example: Product table(pid number,pname varchar2)
i am entering 10 records on date 21/07/2005
i am entering 20 records on date 22/07/2005
i am entering 15 records on date 23/07/2005
i am entering 30 records on date 24/07/2005
If i want to retrieve the records added after 22/7/2005
(ie.) last 45 records
But the table does not contain any date field.
How will you know date & time of each record updated in the table.
If any one knows, help me.
bye.

Query to retrieve the records which have more than one assignment_id

Hello,
I am trying to write a query to retrieve all the records from the table per_all_assignments_f which has more than one different assignment_id for each person_id. Below is the query i have written but this retrieves the records even if a person_id has duplicate assignment_id's but i need records which have more than one assignement_id with no duplicates for each person_id
select assignment_id ,person_id, assignment_id
From per_all_assignments_f
having count(assignment_id) >1
group by person_id, assignment_id
Thank You.
PK

Maybe something like this?
select *
From   per_all_assignments_f f1
where exists (select 1
               from   per_all_assignments_f f2
               where f2.person_id = f1.person_id
               and    f2.assignment_id != f1.assignment_id
              );Edited by: SomeoneElse on May 7, 2010 2:23 PM
(you can add a DISTINCT to the outer query if you need to)

SQL Query to retrieve the records

Hi All,

Now I want to retrieve remaining records. Pelase let me know the query which are not available in emp table between the given limit.
Thank you.

Hi ,
For example there are 10 records only.
I gave
select * from emp where empno in (1,10)
t displays the records having the empnos 1,3,4,6,8
Now I want to display the records 2,5,7,9,10 also...
Please let me know the query.Are use using an oracle database? My Oracle database would never return such a result for your query.
Please post some output from an sqlplus session where you show us exactly what you do.

SQL Plus: retrieve the commands

11g R2 (11.2.0.3) on Linux. At the SQL Plus prompt such as SQL>, I typed some commands, say, select from test;* Sometime I want to re-use the query, so I need to retype in select from test.* Is there a way to retrieve the earlier issued commands back?
Also, I can not use the BACK arrow key. Suppose I want to insert or delete a character in the middle of the commandline, how can I move the cursor over the character?
Thanks

The utility is called rlwrap. You use it to run sqlplus. I alias it. So in my +.bash_profile+, I will have the following line:
alias sqlplus="rlwrap $ORACLE_HOME/sqlplus"It provides full command line recall (inside SQL*Plus) and command line editing.
There is no rlwrap rpm available for installation AFAIK. I'm downloading the source code and doing a manual build and install for all the server installations I do (I do not use Oracle Linux or RHEL as a desktop o/s - think for my Ubuntu desktop it installed via an <i>apt-get</i>). For a manual source code build, you need to install a couple of development rpm's as I recall, such as the readline lib.

SQL to group the records and apply logic to pick one record from each group

I am looking for a query to group the records on certain columns in a table and then from each group I want to pick only one record based on certain rules.
May be having data laid out will make my point more clear to you. Here you go :

So in my example here we have 2 set of records grouped based on the columns specified.
Also we have one more table, PAGE_RANK, which has a rank corresponding to each ad_page number. Here 1 is higher rank than 2. Hence ad page 'A' takes priority over 'B'. Similarly for all other ad pages.
Now, we need to pick one ad from each group of ads by determining the highest ranked ad page within the group and the value for mult and retail must be replaced with the value that has min(retail/mult). So, using the above data we will have the one having ad page = 'A' and ad page = 'D' as the final results since they have highest ad page rank in their group.
The value for mult and retail values for ad_page 'A' = min (10/5 , 1/1, 15/6) = 1,1(mult,retail).
The value for mult and retail values for ad_page 'D' = min (20/4 , 15/5, 2/1) = 1,2(mult,retail).
Finally I have this query below
SELECT a.file_name,
       a.activity_start,
       a.activity_end,
       a.division,
       a.item_code,
       FIRST_VALUE (a.mult) OVER (PARTITION BY a.file_name, a.activity_start, a.activity_end, a.division, a.item_code ORDER BY (a.retail /

                                                                                                    mult,
       FIRST_VALUE (a.retail) OVER (PARTITION BY a.file_name, a.activity_start, a.activity_end, a.division, a.item_code ORDER BY (a.retail /
                                                                                                                                  a.mult))
                                                                                                  retail,
       FIRST_VALUE (a.ad_page) OVER (PARTITION BY a.file_name, a.activity_start, a.activity_end, a.division, a.item_code ORDER BY (b.RANK))
                                                                                                 ad_page,

Frank,
You are marvelous.
That is what I was expecting, but basically I want to display the row with highest page rank which is 'A' and 'D' in this case.
So I have changed my query as below using yours :

But that is what I wanted and your input greatly helped me to save lot of time by using in one single query.
Earlier I was using cursor to do that and it was not doing any good performance wise.
Thanks to every body for your time and your efforts.
I appreciate it.

Stored pl/sql procedure retrieving similar records from different tables using

Hi all I'm trying to retrieve the employee num and employee name if they are both a driver and mechanic
I'm script my own procedure and it compiles with no issue but when i try to execute it. they will show me this error.
Error starting at line 29 in command:
EXECUTE VERIFY(1,'John Smith')
Error report:
ORA-01422: exact fetch returns more than requested number of rows
ORA-06512: at "CARSON.VERIFY", line 8
ORA-06512: at line 1
01422. 00000 - "exact fetch returns more than requested number of rows"
*Cause:    The number specified in exact fetch is less than the rows returned.
*Action:   Rewrite the query or change number of rows requested
This is how my procedure look like:
CREATE OR REPLACE PROCEDURE VERIFY(
enum IN NUMBER,
ename IN VARCHAR) IS
empnum NUMBER;
empname VARCHAR(50);
Fail EXCEPTION;
BEGIN
select employee.e#, employee.name
into empnum, empname
from employee join driver
on driver.e# = employee.e#
join mechanic
on driver.e# = enum;
EXCEPTION
WHEN Fail THEN
dbms_output.put_line('OK');
END VERIFY;
and this is how i execute the procedure
EXECUTE VERIFY(1,'John Smith');
so may i know what have gone wrong? would be glad if someone is able to enlighten me.

No need for a loop.
Just make sure that your query always returns at most one row. Adding a predicate like 'where rownum=1' is a way to achieve that:
select employee.e#
,      employee.name
into   empnum
,      empname
from   employee join driver on driver.e# = employee.e#
                join mechanic on driver.e# = enum
where rownum = 1;

BPM - DB Adapter retrieves the record from DB but says modelling error

We are trying to read a record from a view ( The View is a join of two tables ) . And the join condition is on a column called CUSTID ( whose values is also there ) . Looks like the query is executed and the values are retrieved but we get an exception saying "This exception is considered not retriable, likely due to a modelling mistake. " and "Primary keys must not contain null. ".
I am doing a transformation after the results are fetched . I am mapping the values directly to a payload xml . Is there any problem ?
Not sure what the problem is . Please help ! .
TIA

How to compare two rows in PL/SQL and retrieve the values?

Hello,
I have two tables which have identical schemas, one table (tbl_store) is used to hold the latest version, and the other table (tbl_store_audit) holds previous versions. When the latest record is updated, it is inserted into the tbl_store_audit table as a revision, and the updated details are used as the latest record.
For example: The latest version is held in tbl_store, however the tbl_store_audit may hold 5 records which are the past records used before changes were made - these are seen as revisions.
I want to be able to compare what has changed between each revision in the tbl_store_audit table. For example: Out of the 10 columns, the change between revision 1 and revision 2 was the size from XL to XXL. The change between revision 3 and revision 4 was the size XS to M and price 4.99 to 10.99, and so on.
Eventually i will create an APEX report that will show the user the revision number and what was changed from and to.
I seen in a previous post i need to note my oracle version: Oracle version 10.2.0.4.0

Hi,
Like suggested already you should give some sample data and output.
Maybe you would like to have something like this:
-- Sample data
-- Note PK is the primairy key of the source table and rev are the revisions
with tbl_store_audit as
select 1 pk, 1 rev , 1 price , 'XXL' unit_size from dual union all
select 1 pk, 2 rev , 1 price,   'XL' unit_size from dual union all
select 1 pk, 3 rev , 1.4 price, 'XXL' unit_size from dual union all
select 2 pk, 1 rev , 1.4 price, 'XL' unit_size from dual union all
select 2 pk, 2 rev , 1.4 price, 'XL' unit_size from dual union all
select 2 pk, 3 rev , 1.4 price, 'XL' unit_size from dual union all
select 1 pk, 4 rev , 1 price , 'XL' unit_size from dual union all
select 1 pk, 5 rev , 1 price , 'XL' unit_size from dual union all
select 3 pk, 1 rev , 1.2 price, 'XL' unit_size from dual union all
select 3 pk, 2 rev , 1.2 price, 'XXL' unit_size from dual union all
select 4 pk, 1 rev , 1 price , 'XL' unit_size from dual
-- end of sample data
,tbl_store_audit_tmp as
select
pk
,rev
,'PRICE'          field_name
,to_char(price)   field_value
,to_char(lag(price,1) over (partition by pk order by rev) ) old_field_value
from
tbl_store_audit
union all
select
pk
,rev
,'UNIT_SIZE'           field_name
,to_char(UNIT_SIZE)    field_value
,to_char(lag(UNIT_SIZE,1) over (partition by pk order by rev) ) old_field_value
from
tbl_store_audit
-- include all other fields from the table here with it's own union all select ...
select
from
tbl_store_audit_tmp
where
field_value != old_field_value
PK REV FIELD_NAME FIELD_VALUE                              OLD_FIELD_VALUE

1   4 UNIT_SIZE XL                                       XXL
3   2 UNIT_SIZE XXL                                      XL
6 rows selected If you realy want to keep track of all the changes I think it would be better if you make a "after update trigger" on the base table that checks what changed and put that directly in the uadit table.

SQL to retrieve the specific backuppiece to restore the archivelog/datafile

Hi,
Does anybody have any scripts handy to figure out which specific backuppiece to restore if I need to restore a specific archivelog/datafile? i.e.
1. I am using a controlfile and no rman catalog.
2. There is a gap in the Standby site and I need to scp multiple backup pieces to DR site to restore the archivelogs and apply them.
3. I want to query the primary database and find which specific backuppieces I need to scp to restore these files.
Is there a function/Procedure/Package/Table/View/SQL Query available to figure this out?
Thanks a lot.

Thanks Fahd for the reply.
But my question is a bit different. I know the archilogs that are needed and they have already been backed up by RMAN and deleted in primary. I need to restore them in DR but need to scp only those pieces which are holding the gap logs. I dont want to scp all of the backuppieces, just the ones holding multiple logs that I need to apply.
Hope it helps. Thanks for your effort though... Appreciated :)

How to retrieve the records

Actually I have three tables.
Table1
PID varchar(10) primary key
EID varchar(10)
Table2
PID varchar(10) primary key
PDESC varchar(30)
Table3
PID varchar(10) primary key
Value varchar(10)
All the three table PID values will be different. Nothing will be same
Suppose If i want to retrieve all the PID values by single query from all three tables,
how can I do it.

Try like this
select pid from table1
union
select pid from table2
union
select pid from table3

Oracle 8i SQL - Dealing with no records matching a value

Warning: before you read this, please understand I'm no expert on SQL, so it's quite likely I screwed something obvious up...
I'm trying to do a query kind of like the following:
SELECT
BOM.COMPONENT, BOM.QTY_PER, BOM.PARENT, BOM2.PARENT_QTY_PER
FROM
BOM BOM, BOM BOM2
WHERE
BOM2.COMPONENT=BOM.PARENT AND
BOM.TOP_ASSY='ABC-123'
(Don't worry about my punctuation, my company only allows me to do [read-only] queries through Excel, so I don't need the semi-colons)
What I'm doing is pulling information from the bill of materials (BOM) for a particular assembly (BOM.TOP_ASSY). Each assembly has components (BOM.COMPONENT), and each component has a parent part (BOM.PARENT), which it goes into. Each parent part will also have its own parent part, unless the parent part is the assembly for which I'm querying (BOM.TOP_ASSY) - in the example above, the assembly I'm looking for is 'ABC-123'.
This leads me to my problem. Since I'm looking for the QTY_PER for both the component and the parent, I have to refer to two separate copies of the BOM table. And, since BOM.PARENT could equal BOM.TOP_ASSY, and BOM.TOP_ASSY has no parent, so it can't be a component, so it would never be in the column BOM.COMPONENT. Thus, when I run this query, all components that go directly into the top assembly ('ABC-123') are left off the query.
Is there any way to retrieve the records for the components that go directly into the top assembly, and just make BOM2.PARENT_QTY_PER equal to 0? Basically, I only want BOM2.PARENT_QTY_PER to equal something if the parent is also a component, but 0 if it's the top assembly.
Using NVL doesn't help, and since I'm stuck with an Oracle 8i database to query, I can't use CASE...WHEN either (though, I don't even know if this is possible with a case statement or not)...
I don't even know if this is possible, but could someone let me know one way or the other?
Thanks so much!

Hi,
user11033437 wrote:
The whole example with the BOM and BOM2 tables were just an example of what I'm actually doing. What I'm actually doing is much more complex, and since it's all in VBA code, it was much easier for me to make up a simple example then to actually get my SQL out of VBA That's an excellent approach! I suggest you continue with it. Make sure the tiny test situation works as posted, and then, when it does work perfectly, make it a little more like your real case (say, add just one more condition in the WHERE clause), and test again.
(which looks like this:
strSQL = "SELECT "
strSQL = strSQL & "C_BOM.BILL_LEVEL, "
strSQL = strSQL & "C_BOM.COMP_PART_NBR, "
strSQL = strSQL & "C_PART.PART_DESC, " )
But, in the interest of getting my query to work, and hopefully learning a few things in the process, I've extracted my actual SQL, and pasted it below:
SELECT
     C_BOM.BILL_LEVEL,
     C_BOM.COMP_PART_NBR,
     C_PART.PART_DESC,

     PART C_PART,
     PART P_PART,
     BILL C_BILL,
     V087_BOM C_BOM,
     V087_BOM P_BOM
WHERE
     C_PART.PART_NBR=C_BOM.COMP_PART_NBR AND
     P_PART.PART_NBR=C_BOM.BOM_DOC_NBR AND --fixed a typo here from extracting from vba
     P_BOM.COMP_PART_NBR (+) = C_BOM.BOM_DOC_NBR AND
     C_BILL.COMP_PART_NBR=C_BOM.COMP_PART_NBR AND
     C_BILL.BOM_DOC_NBR = C_BOM.BOM_DOC_NBR AND
     ((C_BOM.STATUS = 'RL') AND
     (C_BOM.PART_NBR= 'ABC-123') AND
     (C_BOM.END_EFF_DT>sysdate) AND
     (C_BOM.BEGN_EFF_DT<=sysdate) AND
     (C_BOM.VIEW_CODE<>'E') AND
     (P_BOM.STATUS = 'RL') AND
     (P_BOM.PART_NBR= 'ABC-123') AND
     (P_BOM.END_EFF_DT>sysdate) AND
     (P_BOM.BEGN_EFF_DT<=sysdate) AND
     (P_BOM.VIEW_CODE <> 'E') AND
     (C_BILL.VIEW_CODE <> 'E') AND     <--for some reason my <> is being parsed out here
     (C_BILL.QTY_PER_TYPE <> 0) AND <--for some reason my <> is being parsed out here

ORDER BY
     C_BOM.BILL_LEVEL, C_BOM.BOM_DOC_NBRPART is the table with the information associated with each part in the system
BILL is the table with the bill of materials for each assembly in the system
V087_BOM is a view that I didn't create, but seems to compile the full bill of materials (from the BILL table) for a top-level assembly (so, the BOM for that part, and for all of it's sub-assemblies, and all of their sub-assemblies, etc.)
Does that give a clearer picture of what I'm trying to accomplish?
Edited by: user11033437 on Apr 15, 2009 10:07 AM
Fixed a typo where indicated (P_PART_NBR changed to P_PART.PART_NBR)I see where you made the join condition between p_bom and c_bom an outer join:
P_BOM.COMP_PART_NBR (+) = C_BOM.BOM_DOC_NBRThat says: "join the tables like this if possible, but if there's no match, then pretend there was a match in the table marked with the + sign". The resuolting joined row will have bom_doc_nbr (and all the other columns from c_bom), but comp_part_nbr (and all the other columns from p_bom) will be NULL.
One of those columns is status. Your WHERE clause includes the condition:
(P_BOM.STATUS = 'RL')Since all columns from p_bom are NULL in this case, the condition above will fail, even though the first condition succeeded.
You have to add a + to all the conditions in this query that refer to p_bom, including
...     (P_BOM.STATUS (+)      = 'RL')      AND
     (P_BOM.PART_NBR (+)    = 'ABC-123') AND
     (P_BOM.END_EFF_DT (+) > sysdate)   AND If you want to include rows that have no match in the p_part table, you'll have to make all of its conditions outer-joins, too:
     P_PART.PART_NBR (+) = C_BOM.BOM_DOC_NBRIsn't that annoying about the <> operator? This site treats it as some kind of markup, even inside {code} tags. I'm surprised any of them showed up. Thanks for flagging them with comments.
There's no problem with the other inequality operator, !=. You can use that when you post to this site.

Using PL/SQL to retrieve column names and column values

If I have a table as follows
Table A(
meal varchar2(32),
beverage varchar2(32),
desert varchar2(32));
and the table contains a row
meal beverage desert
pork chops iced tea apple crisp
Is there a way in pl/sql to retrieve the column names along with the values. I have an object type
DATA_DEFINITION_T AS OBJECT (
          "FIELD_NAME"          VARCHAR2(32),
          "FIELD_VALUE" VARCHAR2(32)
I need to store the column name in field_name and the column value in field_value.
So the result would be:
FIELD_NAME = meal
FIELD_VALUE = pork_chops
FIELD_NAME = beverage
FIELD_VALUE = iced tea
FIELD_NAME = desert
FIELD_VALUE = apple crisp
Thanks in advance.

SQL Loader and the bad file

I use SQL Loader to read a file into a table. In my tests a lot of rows are rejected and written to the bad file. But there are no error messages.
Is there a way to find out why the row was rejected.

The Bad File
The bad file contains records that were rejected, either by SQL*Loader or by the Oracle database server. Some of the possible reasons for rejection are discussed in the next sections.
SQL*Loader Rejects
Datafile records are rejected by SQL*Loader when the input format is invalid. For example, if the second enclosure delimiter is missing, or if a delimited field exceeds its maximum length, SQL*Loader rejects the record. Rejected records are placed in the bad file.
Oracle Rejects
After a datafile record is accepted for processing by SQL*Loader, it is sent to the Oracle database server for insertion into a table as a row. If the Oracle database server determines that the row is valid, then the row is inserted into the table. If the row is determined to be invalid, then the record is rejected and SQL*Loader puts it in the bad file. The row may be invalid, for example, because a key is not unique, because a required field is null, or because the field contains invalid data for the Oracle datatype.
