Export (expdp) with where clause

Hello Gurus,
I am trying to export with where clause. I am getting below error.
Here is my export command.
expdp "'/ as sysdba'" tables = USER1.TABLE1 directory=DATA_PUMP dumpfile=TABLE1.dmp logfile=TABLE1.log query= “USER1.TABLE1:where auditdate>'01-JAN-10'” Here is error

Hello,
You should use parameter file.Another question i can see you are using 11g.Why don't you use data pump?.
Data Pump is faster and have more features and enhancement than regular imp and exp.
You can do the following:
sqlplus / as sysdba
Create directory DPUMP_DIR3 for 'Type here your os path that you want to export to';then touch a file:
touch par.txt
In this file type the following the following :
tables=schema.table_name
dumpfile=yourdump.dmp
DIRECTORY=DPUMP_DIR3
logfile=Your_logfile.log
QUERY =abs.texp:"where hiredate>'01-JAN-13' "then do the following
expdp username/password parfile='par.txt'
If you will import from Oracle 11g to version 10g then you have to addthe parameter "version=10" to the parameter file above

Outer Join with Where Clause in LTS

HI all,
I have a requirement like this in ANSI SQL:
select p1.product_id, p1.product_name, p2.product_group
from product p1 left outer join product_group p2 on p1.product_id = p2.product_id
and p2.product_group = 'NEW'
In Regular SQL:
select p1.product_id, p1.product_name, p2.product_group
from product p1, product_group p2
WHERE p1.product_id *= p2.product_id and p2.product_group = 'NEW'
In OBIEE, I am using a left outer join between these two in Logical table Source, and also, Gave
p2.product_group = 'NEW' in WHERE clause of LTS.
This doesn't seem to solve purpose.
Do you have any idea how to convert WHERE clause in physical query that OBIEE is generating to something like
product p1 left outer join product_group p2 on p1.product_id = p2.product_id AND p2.product_group = 'NEW'
I am using Version 10.1.3.4.1
Creating an Opaque view would be my last option though.

Hello
I have read your post and the responses as well. and I understand that you have issues with the Outer Join with where Clause in LTS.
Try this solution which worked for me (using your example ) -
1. In the Physical Layer created a Complex join between PRODUCT and PRODUCT_GROUP tables and use this join relationship :
PRODUCT.PROD_ID = PRODUCT_GROUP.PROD_ID AND PRODUCT_GROUP.GROUP_NAME = 'MECHANICAL'
2. In the General Tab of PRODUCT table LTS add PRODUCT_GROUP table and select Join Type as Left Outer Join.
3. Check Consistency and make sure there are no errors .
when you run a request you should see the following query generated -
select distinct T26908.PROD_ID as c1,
     T26908.PROD_NAME as c2,
     T26912.GROUP_NAME as c3
from
     PRODUCT T26908 left outer join PRODUCT_GROUP T26912 On T26908.PROD_ID = T26912.PROD_ID and T26912.GROUP_NAME = 'MECHANICAL'
order by c1, c2, c3
Hope this works for you. If it does please mark this response as 'Correct' .
Good Luck.

Merge with where clause after matched and unmatched

Hai,
Can anybody give me one example of merge statement with
where clause after matched condition and after the unmatched condition.
MERGE INTO V1 VV1
USING (SELECT     A.CNO XXCNO, A.SUNITS XXSU, A.DDATE XXDD, XX.SUM_UNITS SUMMED
FROM V1 A,
(SELECT
SUM(SUNITS) SUM_UNITS FROM V1 B
GROUP BY CNO) c
WHERE
A.DDATE=0 AND A.SUNITS <>0 AND
A.ROWID=(SELECT MAX(ROWID) FROM V1 )) XX
ON (1=1)
WHEN MATCHED THEN UPDATE SET
VV1.SUNITS=XX.SUMMED
WHERE XX.XXDD=0
WHEN NOT MATCHED THEN INSERT
(VV1.CNO, VV1.SUNITS, VV1.SUNITS)
VALUES (XX.XXCNO, XX.XXSU, XX.XXDD)
WHERE XX.XXDD<>0
i am getting the error
WHERE XX.XXDD=0
ERROR at line 13:

Thanks,

One of the example is there:
http://download-west.oracle.com/docs/cd/B14117_01/server.101/b10759/statements_9016.htm#sthref7014
What Oracle version do you use ?
Besides the condition (1=1) is non-deterministic,
I would expect there an exception like "unable to get a stable set of rows".

Insert with Where Clause

Hi,
Can we write Insert with 'Where' clause? I'm looking for something similar to the below one (which is giving me an error)
insert into PS_AUDIT_OUT (AUDIT_ID, EMPLID, RECNAME, FIELDNAME, MATCHVAL, ERRORMSG)
Values ('1','10000139','NAMES','FIRST_NAME',';','')
Where AUDIT_ID IN
( select AUDIT_ID from PS_AUDIT_FLD where AUDIT_ID ='1' and RECNAME ='NAMES'
AND FIELDNAME = 'FIRST_NAME' AND MATCHVAL = ';' );
Thanks
Durai

It is not clear what are you trying to do, but it looks like:
insert
into PS_AUDIT_OUT(
                    AUDIT_ID,
                    EMPLID,
                    RECNAME,
                    FIELDNAME,

from PS_AUDIT_FLD
where AUDIT_ID = '1'
    and RECNAME ='NAMES'
    and FIELDNAME = 'FIRST_NAME'
    and MATCHVAL = ';'

Hierarchical query with where clause

Hi,
How can I query hierarchically a query with WHERE clause? I have a table with three fields session_id,id and root_id.
When I try with the following query,
select id, level from relation
where session_id = 79977
connect by prior id = root_id start with id = 5042;
It gets duplicate values.
I want the query to show in the hierarchical manner with a filter condition using WHERE clause. Please help me how can I achieve this. If you know any link that describes more about this, please send it.
Thanks in Advance.
Regards,
-Parmy

Hi Sridhar Murthy an others,
Thanks a lot for your/the answer. It's working for me. It saved a lot of other work around without the proper knowledge of hierarchical query. Please send me any link that describes these issues in detail and also I hope as I have mentioned in the other message, same cannot be achieved on views or ( on two different tables ???)
Any way thanks for your reply,
It's working for me.
With happiness,

Populate list by executing query with where clause

Hi,
I m populating my list from database table using following command.
EntityManagerFactory emf = Persistence.createEntityManagerFactory("learning", new HashMap());
EntityManager em = emf.createEntityManager();
String query = "select d from Dept d";
List list = em.createQuery(query).getResultList();
My list is getting populated with all of rows in my database table(dept). The problem is, I cant use where clause in my query string.
String query = "select d from Dept d where d.dept_name='ANYNAME'";
Moreover I cant select even indivisual columns by using following line
String query = "select d.dept_code,d.dept_name from Dept d";
It looks like that my query is getting all rows from table as Object.
What to do to
1. put some where clause
2. get some particular colums instead of all columns
3. apply some table joins in query
plz help.

Hi Alex,
I misunderstood your question. You had mentioned "My list is getting populated with all of rows in my database table(dept). The problem is, I cant use where clause in my query string. "
I thought you might not have permissions to modify the code in the class, and that's why I suggested that you could write new classes.
1) write new classes,? means if I need just two columns from a table >(instead of all columns), do I need to write new class with just two >columns (getters and setters)?You can write a SQL statement anyway you want , there are no restrictions in JDBC , so if you need just 2 columns you can write a custom query for that.
"select column1 as a, column2 as be from table_name where column3 = xyz" etc.
2) Is not anyway to write SQL statement like
select dept_code,dept_name from dept where dept_name='anything'The above SQL is correct, it should work.
3) Stored procedures? can I get some example(code) to get an idea >how to implement complex queries with where clause and joinings >using stored procedures?Stored procedures are specific to the database you are using, Oracle has a particular syntax for store procdures.
You can call stored procedures from JDBC also, search on Google for
"Calling stored procedures from JDBC"

Summary column with where clause

Hi all,
I'm using Oracle Report Builder 10GR2. I have the following issue: In one of the query i have the following result :
Suppliers     0
Suppliers     1408
Total in BGN     1408
Customers      6024
Customers      11779.32
Customers
Total in BGN     11779.32

Taxes      0
Total in BGN     0
Cash      1363.85
Cash      691
Cash      991.23
Cash      688
Total in BGN     2355.08I want to make a sum for these columns where corresponds to description " Total in BGN" . Maybe it is a simple task... Do i have a chance to select from a query in a Report Builder?
If yes, pls specify? Or maybe there is a chance to add a where clause for summary column. But keep in mind that this is one of the queries in the report builder and i have to add summary with this conditions. I cannot change the existing query but probably add a new one.
Any ideas?

Slow split table export (R3load and WHERE clause)

For our split table exports, we used custom coded WHERE clauses. (Basically adding additional columns to the R3ta default column to take advantage of existing indexes).
The results have been good so far. Full tablescans have been eliminated and export times have gone down, in some cases, tables export times have improved by 50%.
However, our biggest table, CE1OC01 (120 GB), continues to be a bottleneck. Initially, after using the new WHERE clause, it looked like performance gains were dramatic, with export times for the first 5 packages dropping from 25-30 hours down to 1 1/2 hours.
However, after 2 hours, the remaining CE1OC01 split packages have shown no improvement. This is very odd because we are trying to determine why part of the table exports very fast, but other parts are running very slow.
Before the custom WHERE clauses, the export server had run into issues with SORTHEAP being exhausted, so we thought that might be the culprit. But that does not seem to be an issue now, since the improved WHERE clauses have reduced or eliminated excessive sorting.
I checked the access path of all the CE1OC01 packages, through EXPLAIN, and they all access the same index to return results. The execution time in EXPLAIN returns similar times for each of the packages:
CE1OC01-11: select * from CE1OC01 WHERE MANDT='212'
AND ("BELNR" > '0124727994') AND ("BELNR" <= '0131810250')
CE1OC01-19: select * from CE1OC01 WHERE MANDT='212'
AND ("BELNR" > '0181387534') AND ("BELNR" <= '0188469413')
      0 SELECT STATEMENT ( Estimated Costs = 8.448E+06 [timerons] )
|
---      1 RETURN
      |
      ---      2 FETCH CE1OC01
          |
          ------   3 IXSCAN CE1OC01~4 #key columns: 2
query execution time [millisec]            |       333
uow elapsed time [microsec]                |   429,907
total user CPU time [microsec]             |         0
total system cpu time [microsec]           |         0
Both queries utilize an index that has fields MANDT and BELNR. However, during R3load, CE1OC01-19 finishes in an hour and a half, whereas CE1OC01-11 can take 25-30 hours.
I am wondering if there is anything else to check on the DB2 access path side of things or if I need to start digging deeper into other aggregate load/infrastructure issues. Other tables don't seem to exhibit this behavior. There is some discrepancy between other tables' run times (for example, 2-4 hours), but those are not as dramatic as this particular table.
Another idea to test is to try and export only 5 parts of the table at a time, perhaps there is a throughput or logical limitation when all 20 of the exports are running at the same time. Or create a single column index on BELNR (default R3ta column) and see if that shows any improvement.
Anyone have any ideas on why some of the table moves fast but the rest of it moves slow?
We also notice that the "fast" parts of the table are at the very end of the table. We are wondering if perhaps the index is less fragmented in that range, a REORG or recreation of the index may do this table some good. We were hoping to squeeze as many improvements out of our export process as possible before running a full REORG on the database. This particular index (there are 5 indexes on this table) has a Cluster Ratio of 54%, so, perhaps for purposes of the export, it may make sense to REORG the table and cluster it around this particular index. By contrast, the primary key index has a Cluster Ratio of 86%.
Here is the output from our current run. The "slow" parts of the table have not completed, but they average a throughput of 0.18 MB/min, versus the "fast" parts, which average 5 MB/min, a pretty dramatic difference.

Hi all, thanks for the quick and extremely helpful answers.
Beck,
Thanks for the health check. We are exporting the entire table in parallel, so all the exports begin at the same time. Regarding the SORTHEAP, we initially thought that might be our problem, because we were running out of SORTHEAP on the source database server. Looks like for this run, and the previous run, SORTHEAP has remained available and has not overrun. That's what was so confusing, because this looked like a buffer overrun.
Ralph,
The WHERE technique you provided worked perfectly. Our export times have improved dramatically by switching to the forced full tablescan. Being always trained to eliminate full tablescans, it seems counterintuitive at first, but, given the nature of the export query, combined with the unsorted export, it now makes total sense why the tablescan works so much better.
Looks like you were right, in this case, the index adds too much additional overhead, and especially since our Cluster Ratio was terrible (in the 50% range), so the index was definitely working against us, by bouncing all over the place to pull the data out.
We're going to look at some of our other long running tables and see if this technique improves runtimes on them as well.
Thanks so much, that helped us out tremendously. We will verify the data from source to target matches up 1 for 1 by running a consistency check.
Look at the throughput difference between the previous run and the current run:

Export/Import with where condition

DearAll,
I am facing a problem in the delete of a huge table that take 3 hours
DELETE FROM HST HST
WHERE JV_TYPE <> 999
and ( HST.VALUE_DATE <= TO_DATE ('31/12/2010','DD/MM/YYYY')
AND HST.TRANS_DATE <= TO_DATE ('31/12/2010','DD/MM/YYYY'))
what i am trying to do is to export the HST table and import it into another table
but what i need to do is to have a dump with where condition including only the needed records in the table not deleted in the DML above as well as the indexes, triggers.
Thanks

If I try the following:
CONN / AS SYSDBA
CREATE OR REPLACE DIRECTORY dpump_dir1 AS '/folder/';
GRANT READ, WRITE ON DIRECTORY dpump_dir1 TO bokprod;
expdp bokprod/bokprod@uat TABLES=HST PARFILE=hst_query.par
In the parfile:
QUERY=hst:"WHERE JV_TYPE <>999 and ( HST.VALUE_DATE > TO_DATE ('31/12/2010','DD/MM/YYYY') AND HST.TRANS_DATE > TO_DATE ('31/12/2010','DD/MM/YYYY'))"
DUMPFILE=exp.dmp
DIRECTORY=dpump_dir1
LOGFILE=exp.log
impdp bokprod/bokprod@uat DIRECTORY=dpump_dir1 DUMPFILE=exp.dmp
TABLES=bokprod.hst REMAP_TABLE=bokprod.hst:hst_imported
My question is:
1- the parameter file, if i put it in the dpump_dir1 directory, is it read by the expdp command?
2- the hst_imported table created by the remap_table command , is it created with the indexes and triggers already existant on hst table?
Appreciate yoyr help Dears

Can't Export data if WHERE clause contains AND/OR

I am able to export the results of a query if the WHERE clause only has one condition. But if there is and AND or an OR, you can right-click and choose Export Data, but nothing happens.
For example, the following will Export just fine:
SELECT * FROM DUAL
WHERE ROWNUM = 1;
But throw in an 'AND', and it won't Export:
SELECT * FROM DUAL
WHERE ROWNUM = 1 AND ROWNUM < 2;
I am running Ver 1.5.3 and haven't applied any patches.

Unfortunately, as part of trying to fix other issues with the export functionality, 1.5.3 introduced problems where certain types of SQL statements wouldn't export (either nothing happened as you are seeing or reporting error messages like ORA-936). While it is not yet perfect, 1.5.5 handles exporting results much better (it copes with your case that fails in 1.5.3), so I would suggest you upgrade to 1.5.5.

Urgent: Performance problem with where clause using IN and an OR condition

Select statement is:
select fl.feed_line_id
from ap_expense_feed_lines_all fl
where ((:1 is not null and
fl.feed_line_id in (select distinct r2.object_id
from xxdl_pcard_wf_routing_lists r2,
     per_people_f hr2
where upper(hr2.full_name) like upper(:1||'%')
          and hr2.person_id = r2.person_id
and r2.fyi_list is null
          and r2.sequence_number <> 0))
or
(:1 is null))
If I modify the statement to remove the "or (:1 is null))" part at the bottom of the where clause, it returns in .16 seconds. If I modify the statement to only contain the "(:1 is null))" part of the where clause, it returns in .02 seconds. With the whole statement above, it returns in 477 seconds. Anyone have any suggestions?
Explain plan for the whole statement is:
(1) SELECT STATEMENT CHOOSE
Est. Rows: 10,960 Cost: 212
FILTER
(2) TABLE ACCESS FULL AP.AP_EXPENSE_FEED_LINES_ALL [Analyzed]
(2) Blocks: 8,610 Est. Rows: 10,960 of 209,260 Cost: 212

Thanks in advance,

Thanks for the reply, but I have already checked what you are suggesting and I am pretty sure those are not causing the problem. The hr2.full_name column has an upper index and the (4) line of the explain plan shows that index being used. In addition, that part of the query executes on its own quickly.
Because the sql is not displayed in an indented format on this page it is a little hard to understand the structure so I am going to restate what is happening.
My sql is:
select a_column
from a_table
where ((:1 is not null) and a_column in (sub-select statement)
or
(:1 is null))
The :1 bind variable is set to a varchar2 entered on the screen of an application.
If I execute either part of the sql without the OR condition, performance is good.
If the :1 bind variable is null with the whole sql statement (so all rows or a_table are returned), performance is still good.
If the :1 bind variable is a not-null value with the whole sql statement, performance stinks.
As an example:
where (('wa' is not null) and a_column in (sub-select statement)) -- fast
where (('wa' is null)) -- fast
where (('' is not null) and a_column in (sub-select statement) -- fast
or
('' is null))
where (('wa' is not null) and a_column in (sub-select statement) -- slow
or
('wa' is null))

Issue in select query with where clause

Hi guys,
I'm facing an issue while using select query with the where clause. When I'm selecting all the data from the table it returns the correct result. But when I'm using the where clause to get the specific rows from the table it returns no rows. But the data I'm trying to fetch using the where condition exists in the table.
Here is my query which causing the issue,
select * from mytable where myfield = 'myvalue'
But if I use the following query it returns the result correctly.
select * from mytable
Also the myfield value 'myvalue' exists in the table.
I have tried by running this query in both SQL Developer and SQL Plus. I have tried this query in mssql as well. It works perfectly and returns correct result sets for both the queries I have mentioned above. I'm unable to predict the issue as I'm new to ORACLE. Please help.
Thanks,
Ram.

Hi Ram,
I experienced an issue similar to this with a varchar2 field. Some of our records had a hidden newline character at the end of them, which was making queries like the one below fail:
select * from employees
where email = '[email protected]'The best way I found to detect this was to use
select 'XX'||email||'XX' from employeesTo make sure that there were no newlines. But that is just a guess. If you could provide some example table data and the outputs of your selects, it would be helpful.

Readonly table with where clause value from previous page

Hi
I am using jdeveloper 10.1.3.
I have a globalhome page where the user enteres a reference number. i have a backing bean for the globalhome page that runs a method to run an sql that seraches for this reference number, if the reference number exsits the user is directed to a detail page.
this detail page should display details of this reference number.
i have set up a read only table to display this data based on a view object with a bind varaible in the where clause.
however i am unsure how to set this bind varaible value to the reference entered in the first globalhome page.
please can anyone advise how to do this.
regards

Hi,
You can follow following steps to achieve this
1) Write a custom method in your Application module like
public void executeMyVO(String bindVarValue)
MyVOImpl vo= getMyVo();
vo.setNamedWhereClauseParam(<bind variable name decalred in VO>,bindVarValue);
vo.execute();
2) Expose the above method to client. (Right click AM-->Client-->Shift method from left to right)
3) In the pagedef of globalhome page, create a method action for the aboce created custom method
4) execute the method action from your backing bean after you run an sql that seraches for this reference number.
Hope this help.

Outer join with where clause in the universe

Hi,
I have two tables such as:
Patient Table (P)                          Territory Table (T)
P. Alignment ID --------------------------   T.Alignment ID
P. Patient ID                                    T. Region
Two tables are joined on alignment ID, follow is how the data looks like
When i run the query only on Patient Table i get the following
e.g.
Select P.Patient ID, P.Alignment ID
from Patient Table (P)
Where P.Data_date=P.Latest data date
----Note that there is a Where clause here always & i get the following result
P.Patient ID         P.Alignment ID
    1                            1a
    2                             2a
    3                            3a
    4                            Null
    5                            Null
Now when i join two tables on Alignment ID
e.g.
Select P.Patient ID, P.Alignment ID,T.Region
from Patient Table (P)
LEFT OUTER JOIN Territory Table (T)
ON P. Alignment ID = T.Alignment ID
Where P.Data_date=P.Latest data date
AND T.Data_date=T.Latest data date
Following is the result:
P.Patient ID         P.Alignment ID
    1                            1a
    2                            2a
    3                            3a
Even with the left outer join it is not brining in the Null values , it seems that because of the WHERE clause the LEFT OUTER is working as a INNER join.
How can i get the Null rows with my join to the territory table ?
Please Advise,
Thanks,
Sheikh

its not letting me atatched the excel extract but the data is simple as i shown above e.g.
Patient Table (P)                          Territory Table (T)
P. Alignment ID --------------------------   T.Alignment ID
P. Patient ID                                    T. Region
Two tables are joined on alignment ID, follow is how the data looks like
When i run the query only on Patient Table i get the following
e.g.
Select P.Patient ID, P.Alignment ID
from Patient Table (P)
Where P.Data_date='01-OCT-2014'
----Note that there is a Where clause here always & i get the following result
P.Patient ID         P.Alignment ID
    1                            1a
    2                             2a
    3                            3a
    4                            Null
    5                            Null
Now when i join two tables on Alignment ID
e.g.
Select P.Patient ID, P.Alignment ID,T.Region
from Patient Table (P)
LEFT OUTER JOIN Territory Table (T)
ON P. Alignment ID = T.Alignment ID
Where P.Data_date='01-OCT-2014'
AND T.Data_date='01-OCT-2014'
Following is the result:
P.Patient ID         P.Alignment ID
    1                            1a
    2                            2a
    3                            3a
Now the whole issue is that the condition in the WHERE clause is making it act like a inner join and iw ant the NULL rows to appear
