Binding string values in SPARQL

I'm having a problem implementing a bind parameter for a SPARQL query using the Jena Adapter. The examples provided in the documentation imply that all of the bound parameters will be URIs, either provided, or results of a subquery. I would like to be able to bind a string as a parameter to the orardf:textContains function.
The existing SPARQL looks like so:
PREFIX ORACLE_SEM_FS_NS:<http://oracle.com/semtech#timeout=5,BEST_EFFORT_QUERY=t,DEGREE=8>
PREFIX rdfs:<http://www.w3.org/2000/01/rdf-schema#>
PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX orardf:<http://xmlns.oracle.com/rdf/>
PREFIX ORACLE_SEM_HT_NS:<http://oracle.com/semtech#leading(?v,t2,t3,t0,t1)>
select ?s ?l ?pl ?v
where {
?s ?p ?v .
?s grantfile#grantFileLabel ?l .
?p rdfs:subPropertyOf grants-base:gmsDataProperty .
?p grants-base:propDisplayLabel ?pl .
filter( orardf:textContains( ?v, "*<SEARCH_PATTERN>*" ))
Is there anyway to setup this query to BIND the *<SEARCH_PATTERN>* using PREFIX or some other way.

Zhe,
Thanks for getting back to me. Maybe it is because I don't quite understand what you have done but that doesn't seem to have worked, at least not the way I expect.
A bit more background. The Knowledge Base is about 40 million triples in 11g r2.0.2. We have a Java front end that is allowing users to search the knowledge base by entering text strings. We interact with the store using the Jena Adapter (v2.6.2 of Jena).
The current query, provided above, actually works quite well most of the time, but it appears that there is some sort of caching being done that I had hoped the binds would help. The first time a query is executed it may timeout, or may return only a handfull of results. If I run it again immediately, it will return the whole result set as if there were no timeouts. Here are a couple of examples with times:
First Test: Search for "Urban"

The problem is that each different search seems to have the same/similar problems. If I change the search criteria, the first search is slow, the subsequent ones are quite fast. Am I barking up the wrong tree with parameter binding? Is there some other way that I can do it?
As a side note, I'm going to write a second post regarding the fact that the BEQ/Timeout doesn't seem to behave consistently.
Regards,
J.P.

How to use bind variable value of one VO as initial value for other VO row?

JDeveloper 10.1.3.3, ADF Faces, ADF BC
Hi,
I have two View Objects: one read only with several bound variables and another editable entity based. Correspondingly there are two ADF Faces pages: first contains search form based on the read-only VO and second create form based on the editable VO. The search form has several hidden fields for some of bound variables because they aren't edited directly by user. These fields are updated with PPR when user selects other search criteria from LOV.
There is a command button in the first page that navigates to the second form. Is there any way to transfer values of bound variables from the first VO to the second VO as initial values of the new row?
I tried to set custom controller for the second page and retrieve search criteria values from request parameter map but values from hidden fields are missing. I think because that these fields are updated by PPR. Of course I can add custom action method to the navigation button and in the method put these values to request parameter map but I hope there is better solution.
Thanks,
Marius

To summarize, given a bind variable value for one VO, on creating a row in a second VO, for 1 of the attributes of the second VO, you want to use the first VO's bind variable value. Correct?
A potential solution ADF BC driven:
1) Ensure you have an AppModuleImpl for your AM
2) Ensure you have a ViewImpl for your 1st VO (where the bind variable will exist) - lets refer to that VO as "Alpha"
3) Ensure you have a ViewRowImpl for your 2nd VO (the one you want to default the value in) - lets refer to that VO as "Beta"
4) For your first VO "Alpha" create the bind variable (say pValue)
5) In your second VO "Beta" ViewRomImpl add following code:
@Override
protected void create(AttributeList attributeList) {
super.create(attributeList);
AppModuleImpl am = (AppModuleImpl)this.getApplicationModule();
String someValue = am.getAlphaView1().getpValue();
setSecondVOAttr(someValue); // change this code to whatever your setter is for the field you want to initialize.
}Hope this helps. Let us know how you go.

CM.

Getting error 025036 while setting bind variable value

Hi,
I have created a view object (ViewObj) having bind variable (Bind_Val).
I am writing custom java method in AppModuleImpl.java, so that I can use that in serviceInterface.
my method is:
public void Met(String a){
ViewObjImpl vo=new ViewObjImpl();
vo.setBind_Val(a);
I tried the below method also:
public void Met(String a){
ViewObjectImpl vo=new ViewObjectImpl();
vo.setNamedWhereClauseParam("Bind_Val",a)
But when I am running the AppModuleServiceImpl.java and select the Met method and pass the value for a. It is giving me error 02036.

Hi Frank,
Thanks for reply. It was helpful.
Please go through the below mentioned two queries.
My sql query is:
SELECT Message.MESSAGE_ID,
MessageProp.VALUE,
MessageProp.MSG_PROP_ID
FROM MESSAGE Message, MESSAGE_PROP MessageProp
WHERE (MessageProp.Key='From' OR MessageProp.Key='To')AND Message.MESSAGE_ID = MessageProp.MESSAGE_ID And MessageProp.Value='B'
and I have created one view criteria where I am giving the condition as MessageId=:Bind_MessageId.
And then I am executing my findViewCriteria method from AppModuleServiceImpl where I am passing the value for Bind_MessageId and I am getting the output as I want.
Now I am modifying my query as:
SELECT Message.MESSAGE_ID,
MessageProp.VALUE,
MessageProp.MSG_PROP_ID
FROM MESSAGE Message, MESSAGE_PROP MessageProp
WHERE (MessageProp.Key='From' OR MessageProp.Key='To')AND Message.MESSAGE_ID = MessageProp.MESSAGE_ID And MessageProp.Value=:Bind_Value
and setting the value for :Bind_Value programatically as:
public void test(String s){
ViewObjectImpl view = this.getViewObj1();
VariableValueManager vm = view.ensureVariableManager();
vm.setVariableValue("Bind_Value",s);
**Note- I have written this custom method in AppModuleImpl.java class
Then firstly I am executing test method from AppModuleServiceImpl to set the value for :Bind_Value. After that I am executing findViewCriteria method but then I am not getting any record.
**Note-I am not getting any error.
I want to set Bind_Value programatically and then I want to execute my FindViewCriteria from serviceInterface.
Thanks,
Rohit

Setting bind variable value programmatically for master and child VO's

Defined following BC:
Serv VO - Master VO, has Bind_cNum (bind variable)
ServDetail VO - Child VO, has Bind_cNum2 (bind variable)
ServViewLink VL - View link between Serv VO & ServDetail VO
in AMModule Impl have custom WS:
public List<ViewRowImpl> getMyServices(String cNum)
List<ViewRowImpl> result = new ArrayList<ViewRowImpl>();
ViewObjectImpl vo1 = getServ(); //Master VO
vo1.setNamedWhereClauseParam("Bind_cNum", cNum);
vo1.setForwardOnly(true);
ViewObjectImpl vo2 = getServDetail(); //Child VO
vo2.setNamedWhereClauseParam("Bind_cNum2", cNum);
vo1.executeQuery();
while (vo1.hasNext()) {
result.add((ViewRowImpl)vo1.next());
return result;
I am passing same cNum parameter to both Serv VO (Master VO) and ServDetail VO (child VO) as above. (this is in addition to view link bind variable :Id)
It shows in the logs that it is setting the values correctly:
<ViewRowSetImpl> <setNamedWhereClauseParam> [382] Serv ViewRowSetImpl.setNamedWhereClauseParam(Bind_cNum, 11771370)
<ViewRowSetImpl> <setNamedWhereClauseParam> [383] ServDetail ViewRowSetImpl.setNamedWhereClauseParam(Bind_cNum2, 11771370)
<ViewRowSetImpl> <doSetWhereClauseParam> [383] Serv ViewRowSetImpl.doSetWhereClause(-1, Bind_cNum, 11771370)
<ViewRowSetImpl> <execute> [385] Serv ViewRowSetImpl.execute caused params to be "un"changed

<OracleSQLBuilderImpl> <bindParamValue> [437] Binding null of type 12 for "Bind_cNum2"
<OracleSQLBuilderImpl> <bindParamValue> [438] Binding param "Bind_Id": 5018
from above log, when ServViewLink_0 is executed, it is changing Bind_cNum2 bind variable to null.

Try executing the vo1 query before setting the bind variable for vo2, then execute the vo2 query (if that's what you want to do).

Binding multiple values for a clause in a PreparedStatement

Is there a way to bind multiple values for the same variable?
Example: select * from catalog where catnum = ?
and cat_num can be 12340-56, 23451-21 43211-00 etc.
so the where condition really is:
catnum in ('12340-56', '23451-21', '43211-00')
Thanks for a lead!

I've not been able to do this in a way I'd call clean. You might think you could do something like:// create a PreparedStatment with
// the following String: select * from catalog where catnum in (?)"
ps.setString(1, "'12340-56', '23451-21', '43211-00'");But the driver tends to escape the stuff you want to go "straight in" to your where clause. So I end up using Statement and building the SQL manually.
I'd be interested in anyone else's solution

How to define the boolean - String value mapping for SelectBooleanCheckBox?

I have a SelectBooleanCheckBox component whose value is bind to a bean property of type String.
<af:selectBooleanCheckbox text="State" label="State" id="sbc1"
value="#{viewScope.myBean.stateText}" autoSubmit="true"/>
The expected value for the Bean property is "Accepted" (for true) and "Rejected" (for false).
Currently, the component return String value "true" for checked and "false" for unchecked.
How do I set up the component so the boolean value can map to my expected String value?

Sumit,
Thanks for the response.
I read that post too. However, I don't have any binding in my case because the component is bind to a bean property instead of an attribute of a view object.
Without the binding in the page definition, I can't find a place to define the mapping between the Boolean value and the expected String value.

How to get the string value from the RichSelectBooleanCheckBox component?

I added a validator to a RichSelectBooleanCheckBox component which is binded to a String attribute of a View Object.
I defined the mapping of boolean value to corresponding String value in the corresponding attribute binding in the page definition.
When the validate() method of my validator was invoked, the new value passed to the validate method() was a Boolean value instead of the converted String value.
I need to write validate() method generically so that it can handle more than one way of mapping boolean values to String values.
How can I get the converted String value in my validator method() from the RichBooleanCheckBox component that was also passed to the validate() method as a parameter?

use:
int num = Integer.parseInt(s);

Parameters To Include Null Or Empty String Values

I have a table that has both Nulls & Empty Strings that I want to use as a Dynamic Parameter. Even though there is an indication of the Null/Empty String value when the parameter prompt comes up, selecting the value of Null/Empty String results in no records being returned. I have a formula to display the values in the report (where I substitute "Unknown" for the Null/Empty String values), but I am not able to do a parameter on that formula.
I guess in general, this is a situation of needing to be able to use a Dynamic Parameter based on a formula field.
Thanks for any assistance!
Edited by: Dragon77 on Apr 2, 2010 9:39 AM

I'd use a SQL Command as the data source for the list of values. Something like this... (MS SQL Server)
SELECT DISTINCT
CASE WHEN t.StringField IS NULL OR t.StringField LIKE ''
THEN 'Unknown' ELSE t.StringField END AS StringField
FROM TableName AS t
ORDER BY StringField
Then use a formula like this in the selection criteria.
IF {?Parameter} = "Unknown"
THEN (ISNULL ({TableName.StringField}) OR {TableName.StringField} LIKE "")
ELSE {TableName.StringField} = {?Parameter}

How to get string value from xml in JSF??

In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

How to get string value from database table using Visual Studio 2005?

Hi,
Im developing plugin in illustrator cs3 using visual studio 2005. I need to get the values eneterd in database. Im able to get the integer values. But while getting string values it is returning empty value.
Im using the below code to get the values from database table

In the above code im geeting project D which is an integer value. But not able to get the project name.
Please some one guide me.

As I said in the other thread, this really isn't the place to ask questions about a database API unrelated to the Illustrator SDK. You're far more like to find people familliar with your problem on a forum that is dedicated to answering those kinds of questions instead.

When a ResultSet is returned to you, it is always positioned before the first row.
You need to insert a rs.next(); after your executeQuery().

Encephalopathic wrote
Again, why?One of the problems (have been dued) in my codelab asks us to write a class as follow
Write a class definition of a class named 'Value' with the following:
a constructor accepting a single integer paramter
a constructor with no parameters
a method 'setVal' that accepts a single parameter,
a boolean method, 'wasModified' that returns true if setVal was ever called for the object.
a method 'getVal' that returns an integer value as follows: if setVal has ever been called, it getVal returns the last value passed to setVal. Otherwise if the "single int parameter" constructor was used to create the object, getVal returns the value passed to that constructor. Otherwise getVal returns 0.
The setVal(int y) returns nothing, so how do I know whether it has been called or not?
Thank you

Can't assign a string value to a member of type TEXT in Calculation Manager

I can assign a string value to that member of type TEXT using a run-time prompt of type StringToNumber.
Example: "My Text Member" = {string_rtp};
However, I need to accompllish the same function without using a run-time prompts.
I have a planning application and I know that text along with all other non-numeric
values are stored on the relational side in the planning application schema.
It seems reasonable to assume that if this can can accomplish
with a run-time prompt that I could do also do it without a run-time prompt.
What appears to be lacking is a function like:
"My Text Member" = @StringToNumber(<String Literal>);
Clearly, this is already being done "under the covers" for run-time prompts. If
would appear to be a minor enhancement to expose such a function to developers.
NOTE: I suppose you would also need to add new syntax/function to identify a string
literal from say a member name. I'm wondering if this is the more difficult challenge
from a product perspective????

When executing a Calculation Manager rule in Planning, the run-time prompt (RTP) is populated by looking up the outline information present in the relational Planning application database. If the RTP is of type TEXT, the strings displayed in the member select are from the from the relational Planning application database too. Subsequently when executing the Rule, the RTP's value is in fact the record ID (a number) which is then saved into the appropriate intersection in Essbase.
You need to bear in mind, the Rule is executed in Essbase. If Essbase needs to "write" a text, it would then need to connect to the Planning relational database to create a new record. The newly created record ID then needs to be feed back to Essbase, in order to store it in the appropriate intersection.
What you are suggesting, comes with a big overhead causing Essbase and the rule to slow. Thus, the disadvantages outweighs the advantages.

How to generate a Unique key based on a some String value

Hello every one,
I am sorry , If I post this question in wrong group... I have a requirement to generate a unique key ( what every it may be alpha, numeric or alpha numeric) based on some String..
For ex : String str = "AbCX" - Gives a unique key based on "AbCX" value..
Is there any way we can get the unique value using Java ?
Thanks

May be not what you are looking for, but here's may idea:
use a sequence (db sequence) and add it the the string value. This way the value is unique, because the sequence is unique. So you could omit the string theoretically, but your requirement is met.
It's very easy to get a unique sequence number from the db using java, depending of the technology you use (which you did not say :-( )

How to pass multiple query string values using the same parameter in Query String (URL) Filter Web Part

Hi,
I want to pass multiple query string values using the same parameter in Query String (URL) Filter Web Part like mentioned below:
http://server/pages/Default.aspx?Title=Arup&Title=Ratan
But it always return those items whose "Title" value is "Arup". It is not returned any items whose "Title" is "Ratan".
I have followed the
http://office.microsoft.com/en-us/sharepointserver/HA102509991033.aspx#1
Please suggest me.
Thanks | Arup
THanks! Arup R(MCTS)
SucCeSS DoEs NOT MatTer.

Hi DH, sorry for not being clear.
It works when I create the connection from that web part that you want to be connected with the Query String Filter Web part. So let's say you created a web part page. Then you could connect a parameterized Excel Workbook to an Excel Web Access Web Part
(or a Performance Point Dashboard etc.) and you insert it into your page and add
a Query String Filter Web Part . Then you can connect them by editing the Query String Filter Web Part but also by editing the Excel Web Access Web Part. And only when I created from the latter it worked
with multiple values for one parameter. If you have any more questions let me know. See you, Ingo
