Dynamic query in weblogic 7.0?

Hi:
I tried dynamic query in weblogic 7.0 for almost a month but still failed. So I wish someone can help me .
I used dynamic query in a session bean.
QueryHome queryHome = (QueryHome) ctx.lookup("java:comp/env/ejb/BooksEJB");
But this line always returns null for queryHome. I am sure my JNDI for CMP 2.0 BooksEJB is right.
I also set <enable-dynamic-queries>True</enable-dynamic-queries>
in descriptor file followed by instructions in bea documentation.
Thanks !

Ace:
Shall I set this parameter in weblogic descriptor file ? If so, how do I set
? Thanks for your information here !

How to enable dynamic query in weblogic 7.0?

Hi,
The documentation explains how to enable dynamic queries and set a
method-permission to control access. If you find the information at the
following link insufficient, let me know.
http://e-docs.bea.com/wls/docs70/ejb/cmp.html#1089703
You enable dynamic queries in your weblogic-ejb-jar.xml file with the following:
<enable-dynamic-queries>True</enable-dynamic-queries>
You can set a method permission as follows:
<security-role>
<role-name>Admin</role-name>
</security-role>
<method-permission>
<role-name> Admin </role-name>
<method>
<ejb-name> EmployeeEJB </ejb-name>
<method-name> createQuery </method-name>
</method>
</method-permission>

Duplicate records for Dynamic Query in WLS 7

I am getting duplicate records back when I run a dynamic query. If I run the same
query via a finder method, I get the correct results.
Here's the query:
SELECT DISTINCT OBJECT(a) FROM Company AS a, b IN a.userRole WHERE b.userId = ?1
AND a.deptId IN ('1', '2', '3')
Company EJB maps to LU_Company (look up table for company)
Company to UserRole is a one-to-many relationship.
The number of duplicates is equal to the number of records I have for the same company_id
in User_Role table.
The ids for the object I should get back are 1, 2, 3.
Instead I get back 1, 1, 2, 2, 2, 2, 2, 3, 3, 3
In the database, company_id 1 occurs twice in user_role table; company_id 2 occurs
five times.
Any ideas of why the dynamic query has this problem whereas the same query for a
finder method works fine?
Thanks for your help.

Thanks Greg, that worked!

Matt,
<sql-select-distinct> needs to be set in <weblogic-query> element. I amgenerating
a dynamic query from within a local client. So I don't have a finderdefined for
this method. (I don't want to define a finder for this method). How doyou suggest
I can use this? Thanks again for your help.

Hi Mike,
I just filed a bug report for this (CR079471). As a work around, you
can
use the
setSQLSelectDistinct flag so the database will weed out the duplicates.
The only thing to
look out for when using this flag is that Oracle will not allow the use
of 'SELECT DISTINCT'
in conjunction with a 'FOR UPDATE' clause, thus,<sql-select-distinct>True
CANNOT be used if
any Bean in the calling chain has a method with <transaction-isolation>
set to
<isolation-level>TRANSACTION_READ_COMMITTED_FOR_UPDATE. Sorry for theinconvenience.

I suppose it should be one of the properties passed to the query findmethod (Query.query.find(String,

I was unable to locate any documentation or examples for the question.
What is the key set the Properties? I know the "GROUP_NAME" is one,which

ps, We are using Weblogic 7 with sp1.
Your help or comments will be appreciated.
Try the stuff described in:

Help on performance with dynamic query

Hi All,
We are using SQL Server 2008R2. In our one of report we are using Dynamic query and it is taking more time to retrieve the data. to retrieve 32 records it is taking 13-15 secs. In my observation in a table variable, created more than 60 columns. In
the SP called one more sp with insert statement.
Please let me know how i can improve performance of the SP.
I know that i have to provide the SP for observation but unfortunately I cannot provide the SP. Please guide me how i can achieve this .
I tried with temp tables by creating indexes on temp tables but i couldn't find improvement in performance.
Waiting for valuable replies.

First of all a "dynamic query" is not "a query" - it is a multitude of them. Some of them may be fast, others may be slow.
There is of course no way we can give specific suggestions without seeing the code, the table and index definitions etc.
We can only give the generic suggestions. As for the code, make sure that you are using parameterised SQL and you are not building a complete SQL string with parameters and all. If nothing else, this helps to make the code more readable and maintainable.
It also protects you against SQL injection. And it also helps to prevent performance issue due to implicit conversion.
You will need to look at the query plan to see where the bottlenecks may be. You should look at the actual query plan. Note that the thickness of the arrows are more relevant than the percentages you see; the percentages are only estimates, and estimates
are often off. Next step is to see if you can add indexes to alleviate the situation. You should also analyse if there are problems in the query, for instance indexed columns that are entangled in expression. If you are using views, make sure that you don't
have views built on top of views etc. This can often result a table appearing multiple times in a query, when one would be enough.

How to find table name(s) in a dynamic query

In one of our (9iAS PORTAL)applications, any user can able to run their query statment and get output. All queries will be executed as dynamic SQL thru' a common shema/user who has 'SELECT' privilege on all tables but all users don't have this privilege on all tables. Now, before executing any query I need to find out what are the table name(s) used in this query to check the privilege for the respective user. How do I extract all table names being used in a dynamic query?.
Thanks
-Krishnamurthy

I guess that his users log in to application first, then application uses one account to log in to database, so application are not direct database user since all users share the same account to database. If so, when a user lgins in, you may write it down from application to a database audit table, and you need to write down the dynamic query to the database audit table too, then you may query that audit table to find out. up to here, it looks that your application has to do more to assign what role to a user running the application, since database does not know what user is assessing it.

SAP MII 14.0 SP5 Patch 11 - Error has occurred while processing data stream Dynamic Query role is not assigned to the Data Server

Hello All,
We are using a two tier architecture.
Our Corp server calls the refinery server.
Our CORP MII server uses user id abc_user to connect to the refinery data server.
The user id abc_user has the SAP_xMII_Dynamic_Query role.
The data server also has the checkbox for allow dynamic query enabled.
But we are still getting the following error
Error has occurred while processing data stream
Dynamic Query role is not assigned to the Data Server; Use query template
Once we add the SAP_xMII_Dynamic_Query role to the data server everything works fine. Is this feature by design ?
Thanks,
Kiran

Thanks Anushree !!
I thought that just adding the role to the user and enabling the dynamic query checkbox on the data server should work.
But we even needed to add the role to the data server.
Thanks,
Kiran

Dynamic Query to display a page of records at a time

I need some help creating procedure with a dynamic query that will query a table and pass out a certain number of records (like records 101 - 200 of 20,000). This procedure will receive the column names, table name, where clause, page number and number of records per page. It will then pass back the requested records to be displayed on a PHP page.
Pseudo Code:
Select Dynamic_Columns, ROWNUM
Into Dynamic_Pl_Sql_Table
From Dynamic_Table
Where Dynamic_Where_Clause
Total_Records_Out := Dynamic_PL_Sql_Table.Count
Modulus := Mod(Total_Records_Out, Total_Records_Per_Page_In)
Total_Pages_Out := (Total_Records_Out - Modulus) / Total_Records_Per_Page_In
If Modulus > 0 Then
Total_Pages_Out + 1
End If
Row_Start = Page_Number_In * Total_Records_Per_Page_In
Row_End = Row_Start + Total_Records_Per_Page_In
Results_Out = Dynamic_Pl_Sql_Table(Row_Start ... Row_End)
Any help with this will be appreciated!

Maybe this will help you
1) If the Serial is 0 then page break
2) total_rows gives you total number of rows selected.
3) you can apply where clause to this and it will give you appropriate records.
select empno, ename, sal,
mod(row_number() over (order by null),5) serial,
count(*) over () tot_rows from emp ed

Dynamic query in where clause while looping in an internal table.

Hi,
Had a small question : How can i make a dynamic query for the WHERE clause while looping at an internal table.
i want to implement a dynamic where clause query for the below example.
it_cfx_col is an internal table and wa_cfx_col is a work area for it_cfx_col
DATA :
i_cfx_col TYPE TABLE OF cfx_col,
wa_cfx_col LIKE LINE OF i_cfx_col.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
LOOP AT it_cfx_col INTO wa_cfx_col
WHERE CREATED_BY = l_name
AND SCENARIO = l_scenario.
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
Now i want to write a dynamic query for the where clause.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
l_where_clause = 'CREATED_BY = l_name'.
l_where_clause2 = 'AND SCENARIO = l_scenario'.
if l_scenario is not initial.
CONCATENATE l_where_clause l_where_clause2
INTO l_where_clause SEPARATED BY space.
endif.
LOOP AT i_cfx_col INTO wa_cfx_col
WHERE (l_where_clause).
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
when i compile this i get an error message as { Statement concluding with "...(l_where_clause)" ended unexpectedly}
Even i changed the initilization of the variable l_where_clause2 to [ l_where_clause2 = 'AND SCENARIO = l_scenario.'. ]
added the end of line demarkation ".", but still i got the same error message.
Is it a limtation in ABAP that i cannot write a dynamic query for the where clause while looping at an internal table?
Regards,
om

Hi savita,
there in no such 1 limitaion in abap for dynamic query .. i think the error meassge is only beacuse of your synatx delcartaion.
>> LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE (l_where_clause).
   count = count + 1.
some business logic implemented using the work     area    wa_cfx_col
   endloop.
afted delclarataion also , in the where statement you should specify both the field name and value bname
   LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE l_where_clause = 'CREATED_BY = l_name' .
   count = count + 1.
hope it helps.

Invoking a web service from dynamic client in weblogic 7

Is it possible to invoke a webservice from dynamic client in weblogic 7. Because i tried and it doesn't work. But it works with WL 8.1
I don't see any samples on the net for weblogic 7.

Hello rss,
If you want to invoke a web service from a JCD you will have to build the SOAP message using JAX-RPC or AXIS and then programmatically creat an HTTP connection.
Or you can leverage the HTTP(S) eWay and then you only have to build the SOAP message.
Or use eInsight. You can import a WSDL into eInsight and eInsight will offer you a business process Activity to invoke the web service operations defined in the WSDL.

On my base page I have a dropdown-box (that will show the table names for searching) and is dynamically populated based on users access e.g. if user A logs in he may see 5 values (these values are basically table names) in a drop down if user B logs in he may see 10 values. I also have two input fields one field a user can enter value and the other field is read only and a torch icon for LOV so the user can search and select values that are populated in the input fields on the base page.
How can I have my LOV that takes in a value selected in the dropdown and anyvalue entered in one of the input fields and search in the table selected in the dropdown box.
Basically my LOV should do a search on the table and some search value passed when clicking on the torch icon. So a user can select any table-name in the drop down and my LOV should do a search only on the selected table. Once on the LOV Popup want to have a search field there but it only searched on the table selected in the dropdown on the based page. And the selected value on the LOV Popup page gets populated in fields on the base page.
Any help is appreciated.
Thanks

Dynamic Query Doubt

Hi,
I need to write a Dynamic Query to get the data from the table by using the Input date parameters.
LIke,
SELECT* from table where date_start between to_date('12-14-2004','mm-dd-yyyy') AND
to_date('12-15-2005','mm-dd-yyyy');
How can i write the above query in dynamic sql as i will get the two dates as input in my procedure
Help me in this

Or more preferably use bind variables with the
EXECUTE IMMEDIATE as, if the query will be called
many times, the bind variables will prevent hard
parsing of the statement each time (i.e. it will be
quicker to execute).blushadow,
Yes, the execute immediate using bind variables is better/faster than not using bind variables, but your first example outperforms your second one. This is due to the fact that execute immediate really closes all cursors, and in your first example the cursors are kept open (yes, even though you issue a CLOSE cur_test) in the PL/SQL cursor cache.

Dynamic query configuration in sender jdbc adapter

Hi,
According my undertsnading in XI.3.0 dynamic query in sender JDBC adapter is not possible.
could any one confirms the possibility of this feature in XI 7.0 .
Thanks,
venu

Hi VJ,
sorry for late responding to your answer.
One of our requirements is the query statement that we write in sender communication channel should be changed dynamically, for example in where condition the condition parameters values required to change.
Thanks,
venu
