How to bind a VO :variable in a WHERE clause to a page parameter

Hello,
I have a VO. This VO has a variable :v in the WHERE clause of the query.
This VO is used by different UI components in a page (a table, a tree). The page already has a parameter defined in his properties #{viewScope.myparam}
What I want is to bind :v to the #{viewScope.myparam}, so that I can specify :v from a parameter in the URL, so that the table immeditaly shows the proper results.
Is there a way to Bind :v to #{viewScope.myparam} directly in the VO definition in the model project? (It seems it is not possilble)
The other alternative is to use ExecuteWithParams, but in this case I do not know how to perform the query without user actions in a trasparent way. I dont want to associate execute operations to UI components.
thanks

No, this can't be done

If you are within a bounded task flow or in an unbounded task flow that does not have this page as its first view (home page) then you can drag and drop executeWithParams as a method call activity. The attribute then should be saved in the pageFlowScope (not the viewScope).
In addition I would use a ViewCriteria instead of "hard wiring" the bind variable to the VO definition. You can then - in the AM data model section - associate the View Criteria with the VO instance yo use in the UI

How to use a lexical variable in a WHERE clause and as a function argument.

Hello,
My report has a lexical variable which has values like 'and id in (1,3,4)'. I want to use this variable in two separate queries. In the first, it is used in the WHERE clause, something like:
.. where date is not null &var;
In the second query, the variable is used in a function call, something like:
select * from table (my_function(&var));
The trouble is that the first query works when the value of the variable is unquoted, but for the second query the value should be quoted.
Does anyone have an idea how I could solve this problem?
Thanks in advance,
Frans

NVL with host variables in a where clause

Does anyone know if using a host variable in a WHERE clause with
the NVL function will actually work if the host variable is null
without using the indicator variable too?
In other words if the variable ":new_prmy_numb" which was
selected previously is actually null, will the NVL know that it
is null without the indicator variable being listed also? The
person at our company who has this in their code says it works
and the rest of us don't see how.
Example:
SELECT recd_a_id from ADDR
WHERE
NVL(prmy_numb,' ') = NVL(:new_prmy_numb,' ')

well firstly have you tried it to see if it works? That would seems to be a rather obvious step, I would imagine.
Anyway, I don't see anything wrong with the code, except that it might be optimized better ...
SELECT recd_a_id from ADDR
WHERE
(prmy_numb = :new_prmy_numb
or (:new_prmy_numb is null and prmy_numb is null))
... might stand more chance of using an index on the column prmy_numb

How To change the ADF View Object query where-clause at RunTime?

I am trying to create a simple display page which will display user data (username, assoc_dist_id, assoc_agent_id, status , etc). The User data is stored in a database table and i am using an ADF Read Only table based on the View Object to display the data on the JSF page.
However, i want to display only the users that a particular person accessing the page has the AUTH LEVEL to see. e.g. If the person accessing the page is an 'ApplicationAdministrator' then the page should display all users in the table, If its a 'DistributorAdministrator' then the page should display only users associated with that Distributor (i.e. assoc_dist_id = :p_Dist_id ) and If its an 'AgentAdministrator' , then the page should display only users associated with that Agent ( i.e. assoc_agent_id = :p_Agent_id).
Currently my af:table component displays all the users in the table because the query for the view object is (select * from users) . However, i want to use the same viewobject and just set the where-clause at runtime with the appropriate parameter to restrict the dataset returned.
Do anyone knows how to accomplish this ?

David,
See the custom method initializeDynamicVariableDefaults() in the SRViewObjectImpl.java class in the FrameworkExtentions project in the SRDemoSampleADFBC sample application. You can find out how to install the demo if you haven't already from the ADF Learning Center at:
http://www.oracle.com/technology/products/adf/learnadf.html
This class is a framework extension class for view objects that adds a neat, generic feature to be able to dynamic default the value of named bind variables. You can read more about what framework extension classes are and how to use them in Chapter 25, "Advanced Business Components Techniques" of the ADF Developer's Guide for Forms/4GL Developers, also available at the learning center above.
It is an example of generic framework functionality that "kicks in" based on the presence of custom metadata properties on a named bind variable. See section 25.3.3 "Implementing Generic Functionality Driven by Custom Properties" in the dev guide for more details. Using this sample code, if you add a bind variable to a view object, and define a custom metadata property named "DynamicDefaultValue" on that bind variable, and set this custom metadata property to the value "CurrentUser", then that bind variable will have its value dynamically defaulted to the name of the authenticated user logged in. If instead you set this custom property to the value "UserRole", then the bind variable will be set to the comma-separated string containing the list of roles that the authenticated user is part of.
Once you've created a framework extension class for view objects like this, you can have the view objects you create inherit this generic functionality.See section 25.1.4 "How to Base an ADF Component on a Framework Extension Class" in the dev guide for more info on this.
By adapting a technique like this (or some idea similar that better suits your needs) you can have your view object query contain bind variables whose values automatically take on the defaults based on something in the user-session environment.

How to set two Conditions Simultaneously in set where clause

Hi,
I have a messgechoice item , and i need to fire messagechoice VO with two conditions.
For Eg:-- we have three Items ProjectContractor& Work Order on a custom Page , now i need work order list should populate on lelection of project & contractor both, so i have apply a fire partial event on contractor where i i get the parameter values as follows:--
CO Code
if("OrderNoself".equals(event))
String value21 = (String)pageContext.getParameter("ProjectName");
System.out.println("The Selected Project Name for self Contractor is "+value21);
String value22 = (String)pageContext.getParameter("ContractorName");
System.out.println("The SelectedContractor Name for ContractorName is "+value22);
Serializable [] params11 = {value21,value22} ;
am.invokeMethod("initWorkOrderNumberself",params11);
AM Code
public void initWorkOrderNumberself(String ProjectName,String ContractorName");
getDprWorkOrderpopVO1().setWhereClause("PROJECT_NAME = " + "'"+ProjectName+"'");
getDprWorkOrderpopVO1().setWhereClause("CONTRACTOR_NAME = " + "'"+ContractorName+"'");
getDprWorkOrderpopVO1().executeQuery();
Now when i run my form then Work order list only populateon set conditions ofContractor NAme only.
Please suggest....

How to use multiple search conditions in the where clause

Hi,
Below is my query
/****** Script for SelectTopNRows command from SSMS ******/

inner join
[ODS].[Staging].[tODS_INF_GLPGL] ON tODS_INF_GLPCT.CTPAGE = tODS_INF_GLPGL.GLPAGE
where
CTACCT like '[0-9][0-9][0-9]-[0-9][0-9][0-9]-63020-4110%'
This one gives me the exact result i want, now if i add one more to my where clause like this
/****** Script for SelectTopNRows command from SSMS ******/
SELECT distinct
ctacct,sum(GLMN02)
--,ctdesc,CTPAGE
--SUM(GLMN02)

CTACCT like '[0-9][0-9][0-9]-[0-9][0-9][0-9]-63020-4115%'
This query doesnt give me the exact values instead it gives me all the weird values.Can someone please help me with how to work on this where clause?
Thanks

Hi Patrick,
This is what i ve tried earlier and it isnt working .If i use the first query
/****** Script for SelectTopNRows command from SSMS ******/
SELECT distinct
ctdesc,SUM(GLMN02)
--,ctdesc,CTPAGE
--SUM(GLMN02)
FROM [ODS].[Staging].[tODS_INF_GLPCT]

--OR
--CTAcct LIKE '[0-9][0-9][0-9]-[0-9][0-9][0-9]-63020-4115%'
and GLYEAR = 2014
and CTDESC = 'Sales'
group by ctdesc
The result set is
Sales
-182273.96
And if i use the second query
SELECT distinct
ctdesc,SUM(GLMN02)
--,ctdesc,CTPAGE
--SUM(GLMN02)
FROM [ODS].[Staging].[tODS_INF_GLPCT]
inner join
[ODS].[Staging].[tODS_INF_GLPGL] ON tODS_INF_GLPCT.CTPAGE = tODS_INF_GLPGL.GLPAGE

and GLYEAR = 2014
and CTDESC = 'Sales'
group by ctdesc
The result set i get is
Sales
-1455441.08
And i verified that CTAcct LIKE '[0-9][0-9][0-9]-[0-9][0-9][0-9]-63020-4115%'
this second line of where clause has not desc as Sales.
I am not sure whats causing the difference in the values.
Can you please help me with this?
Thanks

I see a couple of problems here.
First, what you posted below is not a syntactically valid query. It seems to be part of a larger query, specifically, this looks to be only the GROUP BY clause of a query.

As you discovered, if you attempt to do so, you'll find it doesn't work. If you stop and think about how SQL is processed, it should make sense to you why the SQL is not valid.
If you want to apply a filter condition such as:
trunc(max(RD.DATERECEIVED)) BETWEEN TO_DATE('01/08/2011','DD/MM/YYYY') AND TO_DATE('01/08/2011','DD/MM/YYYY')you should do it in a HAVING clause, not a where clause:

where ....
group by ....
having max(some_date) between this_date and that_date;Hope that helps,

How to use floor(to_number(substr x))) in where clause???

Hi,
I have a column doc_id which value like abcd.01.023. If I
select floor(to_number(substr(doc_id, instr(doc_id, '.', 1)+1, instr(doc_id, '.', 1)+1 )))
it works,
but get ORA-01722: invalid number if I use in where clause like:
Where floor(to_number(substr(doc_id, instr(doc_id, '.', 1)+1, instr(doc_id, '.', 1)+1 ))) =0
Could you tell me how to fix?
Thansk

My guess is that you didn't process the same rows with each query. Maybe you have some where conditions on the 'select' query that filters out the offending rows. If the doc_id value could not be converted to a number is should raise the error in either case.
Besides that, your substring looks wrong to me. Why take "instr(doc_id, '.', 1)+1" characters? Why not just:
floor(substr(doc_id, instr(doc_id, '.') + 1))
Even then, the portion after the first '.' must be a valid number.

How to change operator of join conditions in where clause?

Hello
I have a situation... I want to change the operator between each join conditions in the where clause when these join conditions are not from the same join..
For example, I have the following schema:
Dim1 ------ DimA -------Fact1
Dim1-------DimB -----Fact1
So DimA and DimB are aliasas of one dim table, but the join is different.
Now if I run this model, what I will get in the where clause of the query is:
Where Dim1 = DimA and Dim1 = DimB and DimA= Fact1 and DimB = fact1.
Is there a way I can change these "and" operator to "OR", so that the where clause would look like this: Where Dim1 = DimA and Dim1 = DimB and DimA= Fact1 OR DimB = fact1?
This is different from simply changing the join operator within the same join, because these are different joins and I'd like to control how they relate to each other..
Please help
Thanks

Sometimes, business rules are complex, so there isn't always a way to simplify things. Is your issue that it's complex and error prone, or is it performance due to the OR clauses?
One possibility that will at least make it easier to test and debug is something like this: (pseudocode)
From Table1 Inner join Table2 on x=y etc.etc.
CROSS APPLY
(Select case when a=b and (c=d or e=f) then 1 else 0 end) as Situation1
, case when h=i or j = k then 1 else 0 end) as situation2
, case when l = m then 1 else 0 end) as situation 3
) as CA_Logic_Simplifier
Where situation1 = 1 and situation2 = 1 and situation3 = 1
Although you could say, "Hey, this is basically doing the same thing as before", this approach would be far easier to test and debug, because you can at a glance look at the values for situation1, 2, 3, etc. to see where errors are being introduced.
The cross apply makes the columns situation1/2/3 "instantiated", so they are usable in the where clause. Divide and conquer.

Is it possible to use a variable for the entire where clause in a PL/SQL select statement?Unfortunately yes.
I have a where clause stored as a string in the databaseThis is a really bad idea, like storing the source for half your program in a text file with a bunch of Java or C or FORTRAN code and opening, reading, compiling and linking at run time.
It is slow, slow, slow as you can expect, and dangerous and insecure, since someone could have put a format C: command in your source file, or something equivalently nasty to a database.

Cursor did not return data if using variables in the where clause

ENV: report builder 9.0.4.3.0, DB 10g, OS XP
table and data ctvctyp:
ctvctyp_code    ctvctyp_code_pred
   CO               Z1
   FE                   Z1
FUNCTION get_case_type(case_type VARCHAR2) RETURN VARCHAR2 IS
cursor type_cur is
    select ctvctyp_code
    from ctvctyp
    where ctvctyp_code_pred = :P_case_type; -- if use 'Z1', it will return 'CO','FE'
                                            -- but if 'Z1' is passed in as case_type, it returns null.
temp_type     VARCHAR2(4);
return_type   VARCHAR2(200);
counter       NUMBER;
BEGIN
     return_type := '';
     counter := 0;
     srw.message(20,'in case_type is '||case_type);
     open type_cur;
     LOOP
          FETCH type_cur INTO temp_type;
          EXIT WHEN type_cur%NOTFOUND;
          counter := counter+1;
          if temp_type is NULL then
               srw.message(20,'temp type is null');
          else
            srw.message(20,temp_type);
          end if;
          if counter = 1 then
               return_type := ''''||temp_type||'''';
          else
               return_type := return_type||','''||temp_type||'''';
          end if;
     END LOOP;
     return return_type;
END;
In my p_casetype validation trigger:
function P_CaseTypeValidTrigger return boolean is
     tempCaseType   VARCHAR2(200);
     return_type    VARCHAR2(200);
begin
    :P_CASETYPE := 'Z1'
    return_type := get_case_type;   --- I got null returned.
return (TRUE);
end;
But in sqlplus:
declare a bind variable :P_casetype := 'Z1';
select get_case_type from dual;
returns:   'FE','MI'

cursor type_cur is
select ctvctyp_code
from ctvctyp
where ctvctyp_code_pred = _{color:#0000ff}*:P_case_type;*_{color}Shouldn't be this :p_casetype instead of :p_case_type?

Using a date variable in a where clause

Hi,
I need to run a select query which contains the following
e.g
String query = SELECT APP_DATE, APP_TIME, APP_TYPE, a.CUST_NO
FROM APPOINTMENTS a, PATIENT_DETAILS p
WHERE APP_DATE = " + appDate + " and p.CUST_NO = a.CUST_NO
appData is a java.sql.Date format and contain the date i want to find. The error i get is "Operator = doesn't apply to the types <DATE> and <INT>"
I have also read somewhere that this would return the date at midnight and therefore would not match, how can i fix this. I am using JDataStore for development.
Thanks
Rudy

you want something like this
SimpleDateFormat df = new SimpleDateFormat ("yyyy-MM-dd");
String sql = "SELECT * FROM Table WHERE appDate='" + df.format(appDate) + "';";
Or if you used prepared statements, you could pass the java.sql.Date to it without the need to convert.

How can define an outer join in the where clause of a flowr statement?

Hi- In the sample below I'm joining two views based on username but in this case what I really want to use is an outer join instead. What is the syntax for that? I tried the (+) notation but that didn't seem to work..
CREATE OR REPLACE PROCEDURE proc_ctsi_all is
XMLdoc XMLType;
BEGIN
DBMS_XDB.deleteResource('/public/CTSI/ctsi_all_rpt1.xml',1);
SELECT XMLQuery(
'<Progress_Report>
<Personnel_Roster>
{for $c in ora:view("CTSI_INVEST_NONPHS_SOURCE_V"),
$cphs in ora:view("CTSI_INVEST_PHS_SOURCE_V")
let $username := $c/ROW/COMMONS_USERNAME/text(),
$expertise := $c/ROW/AREA_OF_EXPERTISE/text(),
$phsorg := $cphs/ROW/PHS_ORGANIZATION/text(),
$activitycode := $cphs/ROW/ACTIVITY_CODE/text(),
$username2 := $cphs/ROW/COMMONS_USERNAME/text()
where $username eq $username2
     return
<Investigator>
   <Commons_Username>{$username}</Commons_Username>
<Area_of_Expertise>{$expertise}</Area_of_Expertise>
<Federal_PHS_Funding>
<Organization>{$phsorg}</Organization>
<Activity_Code>{$activitycode}</Activity_Code>
<Six_Digit_Grant_Number>{$grantnumber}</Six_Digit_Grant_Number>
</Federal_PHS_Funding>
</Investigator>}
</Personnel_Roster>
</Progress_Report>'
RETURNING CONTENT) INTO XMLdoc FROM DUAL;
IF(DBMS_XDB.CREATERESOURCE('/public/CTSI/ctsi_all_rpt1.xml', XMLdoc)) THEN
DBMS_OUTPUT.PUT_LINE('Resource is created');
ELSE
DBMS_OUTPUT.PUT_LINE('Cannot create resource');
END IF;
COMMIT;
END;

What you could do is use query within an XMLTable syntax. Via the COLUMNS parameter you then pass the "column" as XMLType to the following XMLtable statement.
little bit like the following
select hdjfdf
from xmltable
   ({xquery}
    PASSING
    COLUMNS xmlfrag xmltype path 'xxx'
   ) a
, xmltable
   ({the other stuff you need}
    PASSING a.xmlfrag
   ...etc
...etc                 I guess something simular can be done via XQuery straight away as well
