Problems with WHERE CLAUSE in selects executed by BAPIs

Dear Experts,
I'm trying to make a SAP Java Connector. My problem is that, when they are called by Java, BAPI functions don't run in the same manner as in SAP testing mode .
I tested two BAPI functions called through my connector and I saw with the debbuger that BAPI functions don't execute the select and loop at with a WHERE clause when they are called by Java, therefore they throw errors. But in the SAP testing mode functions work just fine.
I'm new to SAP and I don't know why this happens. Would you like to explain to me how to fix this problem?
Thank you very much.
Kind regards,
Maricica

I am sorry for my chaotic writing but i cant even explain the problem to myself better and i m not a native.

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:

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))

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"
4) I m using hibernate. can I get any example of using hibernate own >query?Tutorial on Hibernate Query Language:

Problem with IN clause substitution in Sybase

I am experiencing a problem with IN clause substitution in
embedded SQL with a Sybase databse.
My Cold Fusion server is MX 7.
The Database is Adaptive Server Enterprise/12.5.0.3/EBF 10689
IR/P/Sun_svr4/OS 5.8/rel12503/1915/64-bit/FBO/Thu Jan 23 16:05:19
2003
Here's the problem. I have a Cold Fusion variable
bureau_incode which I am using to define the values in my IN
clause. When I comment out my query and display this value to the
HTML page, bureau_incode has the following value:
('OET','OGC','OIG','OLA','OMD','OMR','OSP','OTHER','OWD','PSHSB','WCB','WTB')
My embedded SQL CFQUERY looks like this:
quote:
<cfquery name="qResults" datasource="#request.dsn#">
Select Name,
bureau_code,
Telephone,
CellPhone,
Pager,
Email,
Availability,
Explanation,
Password,
Admin,
last_login = convert(varchar(20),last_login,0)
from PAMS where Availability = 'N'
<cfif #request.seltype# IS NOT "ALL">
and bureau_code IN #bureau_incode#
</cfif>
</cfquery>
When the code runs, I get the error
Error Executing Database Query. Incorrect syntax near 'OET'.
There is no incorrect syntax. Is there any special way to
submit the IN clause to ColdFusion MX 7? Previously, we were using
ColdFusion 4.5 (I believe) server, and the code worked perfectly,
albiet with double-quotes in the replacement string. Any help would
be appreciated. This type of substitution worked nicely in the
previous server version, I can't imagine why it would no longer
work.

No, I am not. The parentheses are part of the #bureau_incode#
coldfusion variable. I've edited the first message to make this
more clear. I have tried the query with the parentheses in the
#bureau_incode# variable, and with the parentheses in the CFquery
with (#bureau_incode#). The results are always the same.
I will indeed try to help with other stuff in the future. :)
Thanks for trying to help!

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.

WHEN NOT MATCHED THEN INSERT

i am getting the error

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,
                    MATCHVAL,
                    ERRORMSG
select '1',
        '10000139',
        'NAMES',
        'FIRST_NAME',
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,

How to create VO with multiple dynamic where clauses on select with UNION?

I am trying to implement the View Object for the UNION query that looks like this:
     select a,b,c...
          from t1,t2,...
          where dynamic_where_clause1
     union all
     select a,b,c,...
          from t11,t12, ...
          where dynamic_where_clause2
There are up to 60 input parameters that are used to generate dynamic where clauses. They are actually created by calling PL SQL function.
So far, I was not able to assign both where clauses to the view object. Is there a workable solution for this problem, besides resorting to programmatic View Object?
I understand that recommended way with UNIONs is to wrap both queries into a parent select:
select * from (
     select a,b,c...
          from t1,t2,...
          where ... -- table relationship joints
     union all
     select a,b,c,...
          from t11,t12, ...
          where ... -- table relationship joints
) QRSLT
     where dynamic_where_clause
Unfortunately this approach doesn't work here, since individual selects are producing unmanageable amount of data and resulting query takes forever to complete.

I afraid I would not have any real benefits from using VO if I replace the entire query with every request. Actually, the performance may suffer.
I solved the problem by creating a POJO Data Control and invoking the custom select query from java. Not sure if it is the best approach to the problem, but implementation time is limited and it works.
Actually, this is not the first time I see the need to implement VO with complicated SQL like select with unions and dynamic pieces. It would be nice to find a solution and not resort to workarounds.

Select sdo_nn with where-clause on large table

Hi spatial-experts,
I've following problem. I use a table with more than 2.500.000 dataset. Every dataset represents one point (SDO_GEOMETRY, SDO_POINT_TYPE) and have further (text) information. (PI (point of interest) table from TeleAtlas mn_pi)
Following Select works fine:
SELECT /*+ ORDERED NO_INDEX(pi IX_PI_FEATTYP) */
sdo_nn_distance(1) distance,
id, feattyp, arnamelc, name, stname, stnamelc, hsnum, postcode
FROM multinet.mn_pi pi
WHERE
pi.feattyp IN ( 9373,9374)
AND
SDO_NN(
pi.geom,
SDO_GEOMETRY( 2001, 8307, SDO_POINT_TYPE(613.86865234375/60, 3002.94677734375/60, NULL), NULL, NULL),
'sdo_batch_size=0', 1) = 'TRUE'
AND rownum = 1
ORDER BY distance
(P.S. IX_PI_FEATTYP is an index on column feattyp, here not used. When I'm using it the select do not work (it last very long...))
When I now modify the where clause to an pi which feat type that does not exists (no entry in table) the select lasts very long (I canceled the select after 5 minutes).
for example: pi.feattyp = 9756
Otherwise I add a further where clause like
AND arnamelc = 'ITA'
the select also works very long. The point are now in italy. refrence point is in germany and is more than 500km away.
Are there some solutions to solve this problems
(should I use for every feat type a own table)?
Why is the select so slow?
Thanks for all helpfully answers,
Matthias

Hi Matthias,
When you use nearest neighbor, Oracle will use the spatial index to find the nearest neighbor that meets the query criteria. It probes into the index, calculates distances, and returns data in distance order.
Using SDO_BATCH_SIZE, it keeps going back to the database, returning more and more records in distance order until the other predicates are satisfied (in your case, pi.feattyp IN ( 9373,9374).
When you specified pi.feattyp = 9756 (which doesn't exist), you told Oracle to keep going and calculating distances for each of the more than 2.500.000 records in the the data set (you killed it after 5 minutes).
I don't know why adding: AND arnamelc = 'ITA' caused Oracle to take extra time. Sometimes I will do a: set autotrace trace exp
then compare plans for something that runs quickly vs. something that runs slowly. If you want to post the plans for the fast and slow versions it might be interesting to look at.
My guess is you may want to look at a solution that incorporates various possibilities. For instance, if there are only a few of some feattyp values, you may want to select those using the non-spatial index then use sdo_geom.sdo_distance to find the closest point rather than risk having to look through a few million values for a match.
I'm sure other people have thoughts as well...
Kind regards,
Dan

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.

PL/SQL Evaluation problem of where clause in case of NUMBER column type

I found the following problem in Oracle® Database 2 Day Developer's Guide 11g Release 1 (11.1) B28843-04:
The sole parameter of function eval_frequency is employee_id IN employees.employee_id%TYPE.
An ORA-01422 exception occurs when the execution reaches the following select command
SELECT e.hire_date
INTO hire_date
FROM employees e
WHERE employee_id= e.employee_id;
A possible cause of the error is that the type of employee_id is NUMBER while the employees.employee_id is NUMBER(6,0) . The result of the selection is the same as there were no WHERE clause at all.
Everything worked fine, when I declared a temporary variable of NUMBER(6,0) for storing the actual parameter of function and used this variable in the where clause, but I consider this "solution" as being no solution.
It is pointless to use %TYPE parameter of a function for flexibility if I must degrade this flexibility by a fixed declaration of a temporary variable of the same type as the column in question.
What is wrong?
The Developer'Guide I used, the Oracle Sql Developer I used or the PL/SQL version ?

Hi,

The variable employee_id is defined as having the exact same type as the eponymous column. Even if it didn't, I believe Oracle will always implicity convert between datatypes when possible, rounding if necessary. That may cause errors, but it isn't causing this error.
No, the error has nothing to do with the data type. It has to do with the ambiguity of employee_id: is it a column, or is it a variable?
The default is that it means the column name, so
WHERE   employee_id = e.employee_idis equivalent to saying
WHERE   e.employee_id = e.employee_idwhich isn't quite the same thing as not having a WHERE clause; rows with NULL employee_id would still be excluded, if there were any.
I think it's best not to use variable names that are the same as column names. You could call the variable v_employee_id, or, since it's an IN-argument, in_employee_id.
If you must use a variable that can be mistaken for a column, then qulaify it with the name of the procedure, like this:
WHERE   eval_frequency.employee_id = e.employee_id
Everything worked fine, when I declared a temporary variable of NUMBER(6,0) for storing the actual parameter of function That makes sens. You probably gave that variable a name that couldn't be mistaken for a column in the table.
