Dynamic sql in BPEL SOA DB Adapters

Hi,
My requirement is to pass parameters to IN clause in SQL query in DB adapter. But my existing query has more than 1 where clause which fetched the details for single employee. Now I want to modify that query.
Existing Query:select a.last_name as LAST_NAME, a.first_name as FIRST_NAME from people a, assignments b where (a.employee_number = #EmpNum1 or a.npw_number = #EmpNum2) and trunc(sysdate) between a.EFFECTIVE_START_DATE and a.EFFECTIVE_END_DATE and a.person_id = b.person_id and b.primary_flag = 'Y' and b.assignment_status_type_id <> 3 and b.effective_start_date = (select max(effective_start_date) from assignments where person_id in (select distinct person_id from people where (employee_number = #EmpNum3 or npw_number = #EmpNum4) and trunc(sysdate) between effective_start_date and effective_end_date) and primary_flag = 'Y' and assignment_status_type_id <> 3) and rownum < 2
For dynamic parameter passing i found that we need to put In clause as shown in link:Neeraj Sehgal - Experimenting with SOA: Pass multiple parameters, dynamic query in Pure SQL in Database Adapter
How to frame original query to have IN clause?

Dynamic SQL in BPEL

Hi All,
Is it possible to construct dynamic SQl query in BPEL/ in DBadapter..?
My usecase is
1)BPEL receives input
2) Input contains <document-id> tags at various parts of input XML, each time no of <document-id> tags may vary
3) I want to include <document-id> tag values in Query construction, but I dont know how many times <document-id> reapeats in the Input..
How to do this case...?
Any suggestions..?
Thanks

Sorry,
I was reading about DB adapter and tried to solve a problem with insert data from file into a table, but the order of data is not correct, so I then desided to
use insert of type instead.
That is the reason for post here.

Build dynamic SQL query in Database Adapter.

Hi All,
I have a requirement to build dynamic sql query at Database Adapter.
My BPEL process is getting search spec as input from siebel. I need to process this searchspec in BPEL and need to build the SQL query dynamically at Database Adapter to fetch the records from DB.
it goes like this....
1. Sieble Search Spec: city1 OR city2 OR city3 OR city4 .....
I need to build query as
select * from S_ADDR_PER where city like 'city1' OR city like 'city2' OR city like 'city3' OR city like 'city4' ......
2. Siebel Search spec: city1 AND country1 AND state1....
I need to build query as
Select * from S_ADDR_PER where city like 'city1' AND country like 'country1' AND state like 'state1' ....
3. Siebel Search spec: state
I need to build query as
select * from S_ADDR_PER where state like '%state%';
Is it feasible in Database Adapter? if its Yes.
Any guidelines to achieve this?
Thank you
Chandra

Service Registry's Dynamic Lookup of BPEL Partner Link not working

Hi,
Software : SOA 10.1.3.1
OS : Windows XP, 2000
I have deployed webservice application (GetMaxOfTwo) which will give me max of 2 values. Registered the WS in OWSM with user authentication. Registered newly generated WSDL in OSR (Oracle Service Registry). A simple BPEL Process will call service as PartnerLink, which is configured as "Enabling Dynamic Lookup of BPEL Partner Link Endpoints". As mentioned in the document made entry in bpel.xml as registryServiceKey property containing the serviceKey value to the partnerLinkBinding section.
The entire scenario is working fine and changed the servicekey value to wrong value in bpel.xml and redeployed, as expected it was giving me error message saying invalid servicekey.
Now deployed GetMaxOfTwo in another application server and registered in OWSM. Intentionally stopped the first GetMaxOfTwo application. In the OSR Service changed the binding with new WSDL of OWSM. As BPEL process enabled with dynamic lookup it should execute without any error. But the results in this case was giving error saying the service was down. (Means it is referring to the old GetMaxOfTwo webservice.
What could be the reason?, something is missing in the configuration?

Hi
I am having trouble making the BPEL and Systinet to work together. I have Systinet and BPEL installed separately on 2 different servers. I deployed my web services and registered them in UDDI. I created a new BPEL process and added a partner link to refer to one of the web service I have registered in UDDI. When I create the partner link, it is forcing me to give the wsdl and it also gives an error message " There are no partner link types defined in current wsdl. Do you want create that will by default create partner link type for you?". If I say "NO' then deployment fails. If I say "Yes", then it creates a new wsdl file on the local server etc and gives "<Faulthttp://schemas.xmlsoap.org/soap/envelope/>
<faultcode>soapenv:Server.userException</faultcode>
<faultstring>com.oracle.bpel.client.delivery.ReceiveTimeOutException: Waiting for response has timed out. The conversation id is 75164a0815ea471a:-3be8c246:117cc377894:-537b. Please check the process instance for detail.</faultstring>". Any help is appreciated.

NULL and dynamic SQL

If table testrh2 has the following columns and data
col1 --> NULL
col2 --> 2
and table testrh has the following columsn and data
col1 --> NULL
How could I write a dynamic SQL statement to join on the nulls? I've written the following block as a starting point.
declare
cursor c1 is select col1 from isis.testrh;
lval varchar2(1000);
lval2 varchar2(1000);
begin
for r1 in c1 loop
lval := 'select col2 from isis.testrh2 where col1 = '||r1.col1;
execute immediate lval into lval2;
dbms_output.put_line(lval2);
end loop;
end;

You can't compare null values with '=' in Oracle SQL.
Null can only be compared with <column> is null .
You can see it when you try these two queries:
select * from dual where null is null; -- you will see one row
select * from dual where null=null; -- you will see no rowsThat's why you have to write something like
(<column1>=<column1> or (<column1> is null and <column2> is null))This should also work with null:
decode(<column1>,<column2>,1,0)=1By the way, why do you use dynamic sql?
lval := 'select col2 from isis.testrh2 where col1 = '||r1.col1;
I think you could replace your two lines ( lval:= ... AND execute immediate) by this:
begin
select col2
into lval
from isis.testrh2
where decode(col1,r1.col1,1,0)=1;
dbms_output.put_line('lval='||lval);
exception
when no_data_found then
dbms_output.put_line('no data found'); -- or whatever you want

How to rename C00n generic column names in a Dynamic SQL report

I have a an interface whereby the user can select 1 to 60 (upper limit) columns out of 90 possible columns (using a shuttle) from one table before running a report.
To construct the SQL that will eventually execute, I'm using a "PLSQL function body returning SQL query" with dynamic SQL. The only problem is that I have to use "Generic Column Names" option to be able to compile the code and end up with c001 to c060 as the column names.
How can I use the names of the selected columns as the report headings rather than c001, C002... etc?
I do not know beforehand which columns, or how many columns or the order of the selected columns.
I know Denes K has a demo called Pick Columns but I can't access his code. I have a hunch though that he may be just using conditions to hide/show the apropriate columns.
thanks in advance
PaulP

Hi Paul
I would change the Heading Type in the Report Details screen to PLSQL and use the shuttle item to return the column values. e.g.
RETURN :p1_shuttle;
I'm assuming the shuttle already has a colon separated list of the column headings in the correct order?
I hope that helps

Unique id in dynamic sql

hi all,
I am using oracle 10g version.
I have one table but i do not have any unique id to identify the row.
I want to have a unique id temporarily in my select statement (dynamic sql) in a stored procedure while fetching the results, so that i can return my results along with the unique id through the cursor.
Please help me...
Thanks in advance to all...

it depends if you have a more than one column that you can uniquely identify and put them together by concatenating you can have a unique id. or a rowid might help you to temporarily identify a row.

How to mention numbers in array while creating dynamic sql

Hi,
I am creating a dynamic sql and in that I am selecting some rows from the table and storing it into the array.
I am firing this sql statement within trigger.
But i got the error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
I took the same sql statement (the one which was created dynamically) in the procedure and tried to run it but it gave me the same error.
=========================================================
Begin

nVal_Array NewValueArray;

=========================================================
I tried using to_number but still the same error.
Can some body please inform me where I am goofing.
Thanks!

I got a different error, but you need to initialise your nval_array and make sure it can hold three values. The following should work:
declare
type NewValueArray is table of varchar2(4000);
nVal_Array NewValueArray := NewValueArray();
Begin
nval_array.extend(3);
Select col1, col2, col3
into nVal_Array(1), nVal_Array(2), nVal_Array(3)
from tab1
where rowid = 'AAAGJZAAGAAAAAWAAV';
EXCEPTION
WHEN others THEN
Raise;
End;

Dynamic sql and cursors

We are running an oracle sql procedure that uses a LOT of dynamic sql. We are using a 3rd party package (SQR) as a sort of shell to run the sql procedure. The 3rd party package passes to us an oracle error. This error says, in effect, that there are no inactive database cursors available and that the sql program is too large to process. We conclude from this that we must increase one or more of the cursor parameters in init.ora (v$parameters). Is this the correct assumption? If not, does anyone know what we can do? We'd prefer not to break up the sql procedure into smaller pieces.

increase the parameter for open cursors.
check, wether all cursors in your programs are closed in time, or if you are using ref cursors from front-ends (e.g. Java JDBC) that this front-ends close these ref cursors , too.
If you want to decrease the size of procedures get rid of comments, superfluos spaces, tabs, etc.
keep a commented version outside vor documentation purposes.
Hope thsi helps

Dynamic SQL and 255 bytes per line limit

Dynamic SQL and GRANT CREATE ANY TABLE

hi gurus,
i have a dynamic SQL in a procedure where a table will be created from an existing table without data.
strSQL:='create table ' || strTemp || ' as select * from ' || strArc || ' where 1=2';
execute immediate strSQL;
without GRANT CREATE ANY TABLE for the user, *"ORA-01031: insufficient privileges"* error during execution.
Is there a way to tackle this issue without providing GRANT CREATE ANY TABLE privilige?
many thanks,
Charles

ravikumar.sv wrote:
The problem is not because of dynamic sql...It probably has something to do with dynamic SQL or, more accurately, dynamic SQL within a stored procedure.
From a SQL*Plus command prompt, you can create a table if your account has the CREATE TABLE privilege either granted directly to it or granted to a role that has been granted to your account. Most people probably have the CREATE TABLE privilege through a role (hopefully a custom "developer role" that has whatever privileges you grant to users that will own objects but potentially through the default RESOURCE role). That is not sufficient to create tables dynamically via a definer's rights stored procedure. Only privileges that are granted directly to the user, not those granted via a role, are visible in that case.
I expect that the DBAs are granting the CREATE ANY TABLE privilege directly to the account in question rather than through whatever role(s) are being used which is why that appears to solve the problem.

Dynamic SQL and IN CLAUSE from Pro C code

Hi Guys,
Tyring to embed sql in Pro C. Here I don't know in hand how many items will be there in the IN Clause of my dynamic sql. Tried this with a loop and then adding actual values to the stement and then executing it. This worked but as this hard coding makes it literal sql and hence hampers performance. Can any one help me with how to put bind variables where we don't know how many of them will be there in a dynamic sql.
Thanks,

Dynamic SQL supports user defined types, try passing a collection and using TABLE(CAST(collection)) in the SQL statement.
In the current approach (creating IN clause at runtime) keep in mind that in a IN clause you can put a maximum of 255 elements...
