Passing literal as bind variable in jena

Dear all,
We are able to use bind variables using the RDFVID id. However if we want to check for a literal using the jena/joseki adapter we are not able to perform the same action. In our case the literal is of type string.
We are using:
* WLS 12.1.0.3.
* Jena adapter 2.11.1.
* Joseki 3.4.4.
* ARQ 2.9.2.
We try to run the following query on the joseki end-point.
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX vcard: <http://www.w3.org/2001/vcard-rdf/3.0#>
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
PREFIX oext: <http://oracle.com/semtech/jena-adaptor/ext/function#>
PREFIX ORACLE_SEM_FS_NS: <http://oracle.com/semtech#no_fall_back,ALLOW_DUP=T,s2s>
PREFIX ORACLE_SEM_HT_NS: <http://oracle.com/semtech#monitor>
PREFIX ORACLE_SEM_UEAP_NS: <http://oracle.com/semtech#f$RDFVID%20in(ORACLE_ORARDF_RES2VID(?))>
PREFIX ORACLE_SEM_UEPJ_NS: <http://oracle.com/semtech#f$RDFVID>
PREFIX ORACLE_SEM_UEBV_NS: <http://oracle.com/semtech#"Lee">
SELECT ?f
WHERE
{ graph ?g { ?p vcard:N ?vn .
?vn vcard:Family ?f .
?p foaf:title "Sen." .}
The result set is empty. Replacing the line 'PREFIX ORACLE_SEM_UEBV_NS: <http://oracle.com/semtech#"Lee">' by any variant is either given an error or the empty set. (Some variants are ("Lee" , Lee, "Lee", 'Lee' )
When we use the generated SQL from jena/joseki, we are able to get the right result if we run the same query in SQLDeveloper. The bind variable we have to use is "Lee" (the bind variable has the quotations included). This will give the correct result set back.
Kind regards,
Max

Hi Max,
In the UEBV field, you need to put in URL encoded String of "Lee"
Please try the following and see if it helps.
%22Lee%22

Passing value to bind variable of another table from one table

hi,
I have a multi select table. When one row is selected from this table (no button is clicked, only selection is done), an attribute from that selected row (say userid) should be passed to the bind variable of another table and the corresponding details of that particular userid should be displayed in the other table. When more than one row is selected, the other table should display no rows.
My main problem is what code has to be written to pass value to bind variable and where it should be written.
Please give me a detailed explaination as soon as possible.
Thank you.

Sorry, didnot add this. The table is multi select table.

Bind variables in jena WLS SPARQL Queries

Dear all,
We have read about the possibilities of the jena support for bind variables in the documentation (http://docs.oracle.com/cd/E11882_01/appdev.112/e25609/sem_jena.htm#RDFRM248). In the following topic of jun 14 2014 (Bind Variables in SPARQL Queries) the problem was already addressed. However we are facing some other problems.
We are using:
* WLS 12.1.3.0.0
* jena adapter 2.11.1.
* Joseki 3.4.4.
* ARQ 2.9.2.
We try to run the following query on the joseki end-point.
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX vcard: <http://www.w3.org/2001/vcard-rdf/3.0#>
PREFIX ORACLE_SEM_FS_NS: <http://oracle.com/semtech#no_fall_back,ALLOW_DUP=T,ODS=6,s2s>
PREFIX ORACLE_SEM_HT_NS: <http://oracle.com/semtech#monitor>
PREFIX ORACLE_SEM_UEAP_NS: <http://oracle.com/semtech#f$RDFVID%20in(?)>
PREFIX ORACLE_SEM_UEPJ_NS: <http://oracle.com/semtech#f$RDFVID>
PREFIX ORACLE_SEM_UEBV_NS: <http://oracle.com/semtech#1264839720472151591>
SELECT ?f ?g
WHERE
{ graph ?g { ?p vcard:N ?vn .
?vn vcard:Family ?f .
?p foaf:title "Sen." .}
The result we get back is however not using the bind variable. It returns the whole list without UEAP/UEPJ/UEBV.
Is there something I missed in the documentation or do I need to set some variables for the use of bind variables?
Kind regards,
Max

Dear Zhe,
The solution provided works! However setting this property was not straight forward for me (but this is more related to WLS).
Setting this JVM property in the arguments of the weblogic server (Server Start) does not work. I've looked through the files for any sign of the property but did not find any. Manually adding this line in setDomainEnv.sh
(adding the variable JAVA_PROFILE = "-Doracle.spatial.rdf.client.jena.allowAP=true") does work though.
Kind regards,
Max

How to pass Text value/bind variable in Export CSV (FLOW_EXCEL_OUTPUT)

I am using the following in Report Definition -> Header
<tr>
<td>
Download
</td>
</tr>
This will give me the standard output in Excel and it will contain columns only specified in SQL query.
I want to import all other bind variables, which I am using in the report (these are not the columns in SQL query). These variables I want to display only once at the top of the Excel.
thanks,
deepak

You can create a csv file manually. See this posting:

How to pass parameter [bind variable or substitution variable] to a view?

How can I pass a parameter [bind variable or substitution variable] to a view in Oracle?
Some will tell me that this is not necessary, that I can only pass the parameter when I query the view, but I found some case where this cause performance issue. In long view where I use subquery factoring [WITH], it's necessary to pass the parameter many time through different subqueries and not only to the resulting view.
In other database (SQL Server, Access), we can pass parameters through query. I can't find how to do that in Oracle. Can some one tell me what is the approach suggest by Oracle on that subject?
Thank you in advance,
MB
What I can do:
CREATE VIEW "HR"."EMP_NAME" ("FIRST_NAME", "LAST_NAME")
AS
SELECT FIRST_NAME, LAST_NAME FROM EMPLOYEES;
What I want to do:
CREATE VIEW "HR"."EMP_NAME" ("FIRST_NAME", "LAST_NAME")(prmEMP_ID)
AS
SELECT FIRST_NAME, LAST_NAME FROM EMPLOYEES WHERE EMPLOYEE_ID IN (:prmEMP_ID);

Views are a form of dynamic SQL and it is hard to predict how they will perform later.
You can't pass parameters to a view. They are not functions. The mechanism to put the values in is what you mentioned, passing the parameter when you query the view.
In other database (SQL Server, Access), we can pass parameters through query. I can't find how to do that in Oracle. Can some one tell me what is the approach suggest by Oracle on that subject? This functionality is not supported.
What I can do:
CREATE VIEW "HR"."EMP_NAME" ("FIRST_NAME", "LAST_NAME")
AS
SELECT FIRST_NAME, LAST_NAME FROM EMPLOYEES;
What I want to do:
CREATE VIEW "HR"."EMP_NAME" ("FIRST_NAME", "LAST_NAME")(prmEMP_ID)
AS
SELECT FIRST_NAME, LAST_NAME FROM EMPLOYEES WHERE EMPLOYEE_ID IN (:prmEMP_ID);Include the bind value when you use the view in a SELECT. The value will be applied to the view at run-time, somthing like
CREATE VIEW "HR"."EMP_NAME_VW" ("FIRST_NAME", "LAST_NAME","EMPLOYEE_ID")(prmEMP_ID)
AS SELECT FIRST_NAME, LAST_NAME FROM EMPLOYEES;
select *
from emp_name_vw
WHERE EMPLOYEE_ID IN (:prmEMP_ID);To use EMPLOYEE_ID I added it to your list of columns in the view so it can be referenced in the WHERE clause. If you don't want to see that value don't select it from the view.

Select One Choice attribute' LoV based on two bind variables, best practice

Hello there,
I am in the process of learning the ADF 11g, I have following requirement,
A page must contain a list of school names which is needed to be fetched based on two parameters, the parameters are student information been inserted in the previous page.
I have defined a read only view "SchoolNamesViewRO", it's query depends on two bind variables :stdDegree and stdCateg.
added that RO View as a view accessor to the entity to which the name attribute belongs, and then add LoV for the name attribute using the ReadOnly view,
added the name attribute as Select One Choice to page2,
and now I need to pass the values of the bind variables of the ReadOnly view,
the information needed to be passed as the bind variables is inserted in the previous page, I could have the data as bindings attribute values in the page2 definition
I have implemented the next two appraoches but both resulted in an empty list :
* added ExecuteWithParams Action to the bindings of the page and then defined an Invoke Action (set refresh condition) in the executable s, set the default values of the parameters to be the attributes values' input value,
in the trace I code see that the binding fetches correct values as supposed , but the select list appears empty, does the this execution for the query considered to be connected to the list ?
* added a method to the ReadOnly view Imp java class to set the bind variables, then I define it as a MethodAction in the bindings , and then create an Invoke action for it , also the select is empty,
if the query been executed with the passed variables, then why the list is empty? is it reading data from another place than the page!
and what is the best practice to implement that requirement?
would the solution be : by setting the default value of the bind variables to be some kind of Expression!
please notice that query execution had the bound variables ( I see in the trace) are set to the correct values.
would you give some hints or redirect me to a useful link,
Thanks in advance

Pass values to bind variales and execute VO query

Hi All,
I have a requirement to add validation to an appraisal page via OAF.
As a part of testing I need to check, if the values in the query of VO is displayed in the page.
VO - QuestAnsValuesVO
EO - QuestAnswerValueEO, QuestFieldEO
The VO query is
SELECT * FROM (SELECT QuestAnswerValueEO.QUEST_ANSWER_VAL_ID, QuestAnswerValueEO.QUESTIONNAIRE_ANSWER_ID, QuestAnswerValueEO.FIELD_ID, QuestAnswerValueEO.OBJECT_VERSION_NUMBER, QuestAnswerValueEO.VALUE, QuestFieldEO.FIELD_ID AS QUEST_FIELD_ID, QuestFieldEO.NAME, QuestFieldEO.TYPE, QuestFieldEO.HTML_TEXT, rank() over (partition by QuestFieldEO.NAME order by QuestFieldEO.FIELD_ID) AS RANK, QuestAnswerValueEO.QUESTIONNAIRE_ANSWER_ID AS QUESTIONNAIRE_ANSWER_ID1 FROM HR_QUEST_ANSWER_VALUES QuestAnswerValueEO, HR_QUEST_FIELDS QuestFieldEO WHERE QuestFieldEO.QUESTIONNAIRE_TEMPLATE_ID(+) = :1 and QuestAnswerValueEO.QUESTIONNAIRE_ANSWER_ID(+) = :2 AND QuestFieldEO.FIELD_ID = QuestAnswerValueEO.FIELD_ID (+)) QRSLT ORDER BY QUEST_FIELD_ID
I am trying to execute this query in the extended controller class so that i can get the values printed on the page. I am getting SQL exception saying - not all variables are bound.
How do i pass values to bind variables :1 and :2 and execute this query?
Please help.
Thanks
Geetha

Geetha,
Instead of :1 and :2 use a named bind variable as part of your VO and then set either a default value or set its value during runtime. See this example on how to create bind variable:
http://formattc.wordpress.com/2010/04/02/custom-java-bind-variable-in-a-where-clause-of-an-adf-view-object/
Once created, you can set its value during runtime either in ApplicationModuleImpl or in ViewObjectImpl class
e.g.,
         ViewObjectImpl view = this.getEmpView();
        VariableValueManager vm = view.ensureVariableManager();
        vm.setVariableValue("empNo", value);
        view.executeQuery();regards,

How to add '%' to a query with bind variables

Hi,
I am using oracle jdeveloper 11g.
I am trying to create a table to display rows using the below query in a jspx page,
select * from ade_txns where series='WORKPLACE_PT.11.1.1.8.0_GENERIC' and transaction like 'rkumara%'
I am using a view with query and binding variables as below,
select * from ade_txns where series= :p_series and transaction like :p_QAEngineer
I will be passing p_QAEngineer using binding variable using 'ExecuteWithParams' using a dropdown(eg: 'rkumara'). But I need to add a '%' to this value as I am using a 'LIKE' clause in my query.
I tried using,
select * from ade_txns where series= :p_series and transaction like :p_QAEngineer+'%'
But this is not working for me.
Can someone please tell me how i can solve this.
Thanks,

How to add regular expression in viewobject bind variables

Bind Variables in Chart

I want to create a chart based on SQL query. SQL query involves a bind variable testdetid as follows:
select
null the_link,
A.questionid Question,
S.score Score
from ELEARN.ANSWERS A, ELEARN.SOLUTIONS S
where A.TESTDETAILID=:testdetid
and A.solutionid = S.solutionid
I want the value that is passed in the bind variable in my "Additional PL/SQL code" chart building wizard's page.
In my Additional PL/SQL code I want to SQL access additional info. based on the testdetid bind variable.
How can it be achieved? Is there any way in which bind variable can be shared across Chart building wizards.

Furthermore, by using the same SQL, I can display chart in "HTML chart". But it does not work in SVGS and flash chart.
I downloaded an example name "Sales Forecasting" from the packaged application and saw this application can display flash chart conditionally (the region within the flash chart has "conditional" word). after studying, I still have no idea how to do.
Please help me solve the issue.
Thanks.

How to pass a bind variable from one SQL Report to Another

Hello~
I've created a link on one SQL Report page (Page 1). I would like a value from Page 1 used in the SQL on Page 2 to determine the result set. The Where Clause in SQL Query containing the bind variable is as follows:
AND hp.party_name = ':District_Account'
When I run Page 1 and click on the link to execute Page 2, I get 'No Data Found'. The setup of the link is as follows:
Column_Name = District_Account
Link Text = #District_Account#
Target = Page in this application
Page = 2
I'm a rookie working in V1.6...any help would be greatly appreciated!
Thanks,
Becky

I don't see any parameter being passed in that URL. A little sample: http://htmldb.oracle.com/pls/otn/f?p=33203:4 
when you click on the edit link the URL looks like this: http://htmldb.oracle.com/pls/otn/f?p=33203:5:16073998852455071705::NO:5:P5_TABLE_NAME,P5_OWNER:PRESIDENTS_THEMES%2CBLUETEST 
where P5_TABLE_NAME and P5_OWNER are the items and PRESIDENTS_THEMES and CBLUETEST are the values. 
The SQL on the filtered report looks like: 
SELECT *
FROM all_tab_cols
WHERE table_name = :P5_TABLE_NAME
AND owner = :P5_OWNER

How to pass a value to a bind variable in a query report in oracle apex

Hi Guys,
I have requirement to send weekly reports via email to some users. The users should receive their own records in the report. The user details is stored in a table. What I am planning to do is to create a report query in oracle apex to generate the report and then run a function/procedure via a scheduler to email the report to respective users. Now my query is ............. is it possible to pass a value (user name) to the report query to pull records of only that user? I know we can have bind variables in the report query but I have no idea how to pass a value for bind variables from a function/procedure.
Can anyone help me on this issue or suggest a better approach?
Thanks,
San

Oracle BI Publisher - Passing multiple wildcard search to a bind variable

Hi,
Please help me in resolving the below mentioned issue:
I have developed a report in oracle BI Publisher with a SQL query.
While scheduling the report to run I used to pass mutilple parameters like CGAMSVC08,RLCSVC51
If the pass the parameter with wildcard search like C% it works.
When I pass two or more parameter values with wildcard search like C%,R% its not working.
Could you please let me know how should I give the bind variable in the SQL query. Currently I'm paramater like the one shown below for passing multiple paramaters:
Where (',' || :PRMRETRID || ',' like '%,'||RL.RETROFIT_ID|| ',%')
Edited by: user1101445 on May 23, 2012 2:02 AM

HI Tyler.
Well, here's the latest.
I found this little gem in the BIEE 10.1.3.3.3 Release Notes Documentation...
This issue applies to Versions 10.1.3.3, 10.1.3.3.1, 10.1.3.3.2, and 10.1.3.3.3.
Reports that use the BI Publisher data template as the data model may fail with the
following error: "Data not defined."
This error will occur if you defined a parameter in your data template but you do not
pass a value to it via the user interface. If you do not specify this parameter in the "Parameters" section of the report definition that you created using the BI Publisher Edit Report interface, then you will receive the error.
To work around this issue, either define the parameter in the Edit Report interface or remove the parameter from the data template.
That bit is now working.
Having set this up and using your guide it works if my SOAP parameters declaration passes a single value like this...
<parameterNameValues>
<item>
<name>P_INVOICE_ID</name>
<multiValuesAllowed>true</multiValuesAllowed>
<values>
<item>16641</item>
</values>
</item>
</parameterNameValues>
But if I try and pass two or more like this...
<parameterNameValues>
<item>
<name>P_INVOICE_ID</name>
<multiValuesAllowed>true</multiValuesAllowed>
<values>
<item>16641,18421</item>

BIP states "java.sql.SQLException: ORA-01722: invalid number"
My SQL where clause is..
<sqlStatement name="Q1">
<![CDATA[select * from vw_invoice_summary
where invoice_summary_id IN (:P_INVOICE_ID)]]>
</sqlStatement>
And the BIP error records the parameter value as P_INVOICE_ID 16641,18421 (which are legit invoice IDs)
In summary, works if I pass one invoice ID, fails if I pass two or more.
Any ideas? Or do you reckon this is now a post for the BIP forum?
Kind regards.

Trying to pass array to stored procedure in a loop using bind variable

All,
I'm having trouble figuring out if I can do the following:
I have a stored procedure as follows:
create procedure enque_f826_utility_q (inpayload IN f826_utility_payload, msgid out RAW) is
enqopt dbms_aq.enqueue_options_t;
mprop dbms_aq.message_properties_t;
begin
dbms_aq.enqueue(queue_name=>'f826_utility_queue',
enqueue_options=>enqopt,
message_properties=>mprop,
payload=>inpayload,
msgid=>msgid);
end;
The above compiles cleanly.
The first parameter "inpayload" a database type something like the following:
create or replace type f826_utility_payload as object
2 (
3 YEAR NUMBER(4,0),
4 MONTH NUMBER(2,0),
83 MUSTHAVE CHAR(1)
84 );
I'd like to call the stored procedure enque_f826_utility_q in a loop passing to it
each time, new values in the inpayload parameter.
My questions are:
First, I'm not sure in php, how to construct the first parameter which is a database type.
Can I just make an associative array variable with the keys of the array the same as the columns of the database type shown above and then pass that array to the stored procedure?
Second, is it possible to parse a statement that calls the enque_f826_utility_q procedure using bind variables and then execute the call to the stored procedure in a loop passing new bind variables each time?
I've tried something like the following but it's not working:
$conn = oci_pconnect (....);
$stmt = "select * from f826_utility";
$stid = oci_parse($conn, $sqlstmt);
$r = oci_execute($stid, OCI_DEFAULT);
$row = array();
$msgid = "";
$enqstmt = "call enque_f826_utility_q(:RID,:MID)";
$enqstid = oci_parse($conn, $sqlstmt);
oci_bind_by_name($enqstid, ":RID", $row); /* line 57 */
oci_bind_by_name($enqstid, ":MID", $msgid);
while ($row = oci_fetch_array($stid, OCI_RETURN_NULLS+OCI_ASSOC))
++$rowcnt;
if (! oci_execute($enqstid)) /* line 65 */
echo "Error";
exit;
When I run this, I get the following:
PHP Notice: Array to string conversion in C:\Temp\enqueue_f826_utility.php on l
ine 57
Entering loop to process records from F826_UTIITY table
PHP Notice: Array to string conversion in C:\Temp\enqueue_f826_utility.php on l

e 65
PHP Notice: Undefined variable: msgnum in C:\Temp\enqueue_f826_utility.php on l
ine 68

Exiting!

Thanks for the reply.
I took a look at this article. What it appears to describe is
a calling a stored procedure that takes a collection type which is an array.
Does anyone from Oracle know if I can pass other database type definitions to a stored procedure from PHP?
I have a type defined in my database similar to the following which is not
an array but a record of various fields. This type corresponds to a payload
of an advanced queue payload type. I have a stored procedure which will take as it's input, a payload type of this structure and then enqueue it to a queue.
So I want to be able to pass a database type similar to the following type definition from within PHP. Can anyone from Oracle verify whether or not this is possible?
create or replace type f826_utility_payload as object
YEAR NUMBER(4,0),
MONTH NUMBER(2,0),
UTILITY_ID NUMBER(10,0),
SUBMIT_FAIL_BY VARCHAR2(30),
MUSTHAVE CHAR(1)
);

How to pass a list as bind variable?

How can I pass a list as bind variable in Oracle?
The following query work well in SQL Developer if I set ":prmRegionID=2".
SELECT COUNTRY_ID,
COUNTRY_NAME
FROM HR.COUNTRIES
WHERE REGION_ID IN (:prmRegionID);
The problem is that I can't find how to set ":prmRegionID=2,3".
I know that I can replace ":prmRegionID" by a substitution variable "&prmRegionID". The above query work well with"&prmRegionID=2" and with "&prmRegionID=2,3".
But with this solution, I lost all advantage of using binds variables (hard parse vs soft parse, SQL injection possibility, etc.).
Can some one tell me what is the approach suggest by Oracle on that subject? My developer have work a long time too find how but didn't found any answer yet.
Thank you in advance,
MB

So the actual problem is that you are using the WRONG data type - you want a data type that can have more than a single string (or numeric) value. Which means that using the string (varchar2) data type is the wrong type - as this only contains a single value.
You need to understand the problem first. If you do not understand the problem, you will not realise or understand the solution too.
What do you want to compare? What does the IN clause do? It deals with, and compares with, a set of values. So it needs a set data type for the bind variable. A set data type enables you to assign multiple values to the bind variable. And use this bind variable for set operations and comparisons in SQL.
Simple example:
SQL> --// create a set data type
SQL> create or replace type TStringSet is table of varchar2(4000);
2 /
Type created.

SQL>
SQL> var c refcursor
SQL>
SQL> --// use set as bind variable
SQL> declare
2          names   TStringSet;
3 begin
4          --// assign values to set
5          names := new TStringSet('BLAKE','SCOTT','SMITH','KING');
6
7          --// use set as a bind variable for creating ref cursor
8          open :c for
9                  'select * from emp where ename in (select column_value from TABLE(:bindvar))'
10          using names;
11 end;
