Hi,
<div class="jive-quote">How to change query dynamically in DB Adapter?</div>
Unfortunately there is no way to pass the query dynamically in DB Adapter. The reasoning behind that is that the DB adapter configuration wizard creates multiple assist files for each operation including the xsd which can not be created for any query dynamically.

Either use XA datasources or throw a rollback fault in the catch block.

Changing query dynamically

Hi,
I have a requirement based on the parameter passed by the user i need to execute diffent queries.
For suppose
I have defined one query Group1,
SELECT ALL TMP_AUFSTELLUNGPOSITIONEN.TAP_SACH_KTO, TMP_AUFSTELLUNGPOSITIONEN.TAP_KOSTENST,
TMP_AUFSTELLUNGPOSITIONEN.TAP_PROJEKT, TMP_AUFSTELLUNGPOSITIONEN.TAP_ASG_NR,
TMP_AUFSTELLUNGPOSITIONEN.TAP_ABR_VON, TMP_AUFSTELLUNGPOSITIONEN.TAP_ABR_BIS,
TMP_AUFSTELLUNGPOSITIONEN.TAP_SEGMENTTEXT, TMP_AUFSTELLUNGPOSITIONEN.TAP_WAEHRUNG,
TMP_AUFSTELLUNGPOSITIONEN.TAP_ANZAHL, TMP_AUFSTELLUNGPOSITIONEN.TAP_NETTO_GESAMT,
TMP_AUFSTELLUNGPOSITIONEN.TAP_POS_TEXT1
FROM TMP_AUFSTELLUNGPOSITIONEN
WHERE TMP_AUFSTELLUNGPOSITIONEN.TAP_ASG_NR = :DOCUMENTNUMBER
If user passes Type as 1 the above query should execute else the below query should execute
select TAP_ABR_VON,TAP_ABR_BIS, TAP_PROJEKTBEZ, SUM(TAP_NETTO_GESAMT) as SUMTAP from TMP_AUFSTELLUNGPOSITIONEN
where TAP_ASG_NR = :DOCUMENTNUMBER group by TAP_ABR_VON,TAP_ABR_BIS,TAP_PROJEKTBEZ,TAP_STEUSCHL
The layout should be same for both the reports only diffence is some fields will be displayed and some other won't.
I should i do it for this?
Can u help me sloving above problem.
Thanks
Kalyan

Kalyan,
Good question!
You are correct. Each query would be in a separate group, so the number of possible values for the parameter would = the number of queries/groups.
So if you have 3 queries, in the layout view, you need 3 repeating frames. I would draw a regular frame, and put your repeating frame inside. Then, below it, draw another frame, and your 2nd repeating frame. Below that, draw your 3rd frame and repeating frame. So now you have 3 repeating frames.
On the first frame (goes with group 1) right click on the outermost regular frame, and click F-11 for a format trigger. Add this part to the code:
IF :P_PARAM = 1 then
return (true);
else
return(false);
end if;To Frame 2 Add this:
IF :P_PARAM = 2 then
return(true);
else
return(false);
end if;And to frame 3 add this:
IF :P_PARAM = 3 then
return(true);
else
return(false);
end if;If you are having trouble read up on format triggers. When the user select a value as a parameter, only one of the queries (groups) will execute, and only one of the frames will print.
I am going to attemp to draw a layout of what you need.
Frame 1
Repeating Frame 1
White Space
Frame 2
Repeating Frame 2
White Space
Frame 3
Repeating Frame 3

How to change VO query dynamically

Hi,
Iam trying to change the VO query dynamically. My req. is I have 6 columns in a header page 3 columns(default single column) for sorting purpose and another 3 columns(default single column) for data querying purpose.
al these are in one view so I have created one VO.
Sorting Searching
A A
B B
C C
When I give any values in Sorting and hit submit button VO query should change dynamically.
I have searched older post regarding this.
My query is some thing like this
SELECT * from cust_table where a = NVL(:1 ,a)
UNION
SELECT * from cust_table where a<> NVL(:1 ,a)
order by a
Iam trying to pas the below part dynamicaly in my AM method
vo.setWherecaluse("where a = NVL(:1 ,a)
UNION
SELECT * from cust_table where a<> NVL(:1 ,a)
order by a ")
and trying to pass the params to that query. But it is not working.Giving error "Bind variable could not find"
Can any one suggest how to solve the issue.
Thanks,
Mahesh

Hello Ajay,
THanks for your response.
My vo query is select col1,col2,col3,col4,col5,col6 from cust_table;
and and changing vo.setwhereclause dynamically based on different scenerios.
in one scenerio i need my query to be some thing like
SELECT col1,col2,col3,col4,col5,col6 from cust_table where a = NVL(:1 ,a)
UNION
SELECT col1,col2,col3,col4,col5,col6 from cust_table where a <> NVL(:1 ,a)
order by a
so can i concatenate my vo.setwhereclause like *"where a = NVL(:1 ,a) UNION SELECT col1,col2,col3,col4,col5,col6 from cust_table where a NVL(:2 ,a) order by a"*
in the setwhereclause iam setting bind variables is this method correct? Hope it is clear pleaselet me know if it is not clear I will explain in detail.

Dynamic destinations for adaptive web service in webdynpro for java

Hi,
Please advice me on how to create dynamic destination for adaptive web service model in webdynpro for java.
Regards,
Patana

Hi,
If this is the case, then use the HTTP destination for this.
What you need to do is:
1. Create one HTTP destination in visual administrator at services-> Destinations. Provide HTTP url of the your web service and the security options.
2. Specify this HTTP destination in the code before executing web service model.
Write following code for that:
wdContext.current<node name>Element().modelobject()._setHTTPDestination(<Specify HTTP destination name>);
Then execute your web service model.
Now, whenever you want to change the server on which your web service is running, make change in the HTTP Destination in visual administrator.

Custom query conditions in db adapter

Hello,
How to execute custom query in bpel db adapter?
For example :
1. select * from employee where status = 'N' and address is not null
2. select * from empoyee where substatus = 'Y' and phone is null
after where keyword - query part is dynamic, parameter combinations and count is unlimited ( depends on business logic ). It is not possible to implement each condition parameter as parameter in db adapter configuration.
Db adatper query has to be something like : select * from employee where #condition# , but #condtion# need to be interpretated as condition not string with quotes..
best Regards,
Uldis

Say your complete query looks like this -
select SUBJECT_NAME from RELATION
where PID_GID_SSID IN (select PARTY_KEY from xref WHERE row_id='123')
1). In assign activity, write out the query part which comes after where clause and assign to variable query
(select PARTY_KEY from xref WHERE row_id='123') , replace the value of row_id from input value in assign.
2. Now open DB adapter and pass the rest of query as input -
select SUBJECT_NAME from RELATION
where PID_GID_SSID IN #query

Dynamic conifguration for adapter module

com.sap.aii.mapping.api.DynamicConfigurationKey
Class used to create a key object for an adapter-specific attribute. The key object comprises the adapter namespace and the property name.
●     com.sap.aii.mapping.api.DynamicConfiguration
Class used to read, change, or delete the value of an adapter-specific attribute. In a method, you use objects of type DynamicConfigurationKey to access the attributes

For Module Processors, check Adapter-Specific Message Attributes of the following link:
http://help.sap.com/saphelp_nw2004s/helpdata/en/17/50d440e14f8431e10000000a1550b0/frameset.htm
The methods to set/get Attributes in Adapter Module are:
Message.setMessageProperty()
Message.getMessageProperty()
The following info can be obtained in javadoc:
getMessageProperty
public java.lang.String getMessageProperty(java.lang.String namespace,
                                           java.lang.String name)
    Returns the value of an additional message property, in case that such an value exists.
    Parameters:
        namespace - The namespace of the property to get.
        name - The name of the property to get.
    Returns:
        The value for the given namespace/name combination, or null, when no such value exists.
setMessageProperty
public void setMessageProperty(java.lang.String namespace,
                               java.lang.String name,
                               java.lang.String value)
                        throws InvalidParamException
    Sets an additional message field, if supported by the Message profile implementation. Such additional fields will not be visible as an own table column in the MS message monitoring, since it is to be stored as part of the message header. This mechanism allows different protocol implementations to support more message fiels, as per default available in the MS Message interface. Such fields can be accessed through this API method, without casting to the specific Message implementation.
    Parameters:
        namespace - The namespace of the property to set.
        name - The name of the property to set.
        value - The value of the property to set. When null is given as the value param, an already set value will be deleted.
    Throws:
        InvalidParamException - If either the length of one of the parameters is too long, or in case of an unknown/not allowed namespace/name combination (but only if the Message implementation has the necessary knowledge about the valid namespace/name pairs).

Changing LOV Dynamically

Dear Members,
I have an OAF Page which has 6 records.
When user is in first record, I want to attach XXLOV1 to FIELD1 by changing the where clause. Similarly when user is in 2 nd record I want to attach XXLOV1 to FIELD1 by changing the where clause dynamically and so on..
Kindly please let me know how to acheive this requirement.
Many thanks in advance.
Best Regards,
Arun Reddy D.

Hello Anil,
Thank you very much for your reply. Iam a beginner to OAF.
Can you please elaborate your answer.
Actually I have page where I am displaying FIELD1 6 times i.e., 6 records.
When the cursor is in first record I want to attach the lov with certain query criteria by changing the where clause. Similarly when the cursor is in second record, I want to change the same lov's where clause and attach it to the same field i.e., FIELD1 and son on.
Here if we have an event to the field how we will know that whether it is first record or second record .... to change the lov query dynamically.
Here my main problem is Iam not able to find out user is in which record to change the lov dynamically. Can you please give me some hint to find out the record number in which the cursor is so that i can change the lov dynamically.
Many thanks in advance.
Best Regards,
Arun Reddy D.

Assigning a query dynamically to a cursor based on IF ELSE condotion

hello guys,
we are facing a problem while creating a procedure.
The procedure has been recreated in ORACLE from SQL SERVER 2005.
the problem is that in SQL server we can assign a query dynamically to a cursor so that it will be called at execution time.But this is not the case in oracle, i.e in Oracle its not allowed to assign a query to a cursor dynamically(OR IS IT...!!!)
the code is
vr_SQL varchar2(400);
declare
   cursor ord_cur ; <-----cursor declaration
begin
   If v_pIsScrutiny = 0 then   +<--------------second condition+
      vr_SQL:='Select NVL(ServiceID,0) ServiceID,OrdQty,+<-------query assignment to a variable+
          NVL(DrugID,0) DrugID,NVL(ServiceAmount,0) Rate,OrdDtlID
          from Orderdtl inner join ordermst on Orderdtl.OrdID = ordermst.OrdID
          Where Orderdtl.OrdID in (Select OrdID From Ordermst Where OrdVisitID = vr_visitid
          and TO_CHAR(ordermst.OrdDate,''DD-MON-YYYY'')
          Between TO_CHAR(vr_pActivationDate,''DD-MON-YYYY'')
          and TO_CHAR(vr_pExpiryDate,''DD-MON-YYYY'')
          ) And NVL(Orderdtl.Cancelled,0) = 0 And NVL(Orderdtl.PackageID,0) = 0
          and NVL(Orderdtl.DrugID,0) = 0;';
    Else +<--------------first condition+
        Update OrderDtl Set PackageID = 0 , AllocationID = 0 , ConsumptionID = 0
        Where OrdID in (Select OrdID From Ordermst Where OrdVisitID = vr_visitid)
        And AllocationID = v_pHCPAllocationID;
       vr_SQL:= 'Select NVL(ServiceID,0) ServiceID, +<-------query assignment to a variable+
       OrdQty,NVL(DrugID,0) DrugID,NVL(ServiceAmount,0)
        Rate,OrdDtlID
       from Orderdtl inner join ordermst on Orderdtl.OrdID = ordermst.OrdID
       Where Orderdtl.OrdID in (Select OrdID From Ordermst Where OrdVisitID = vr_visitid
       and TO_CHAR(ordermst.OrdDate,''DD-MON-YYYY'')
       Between TO_CHAR(vr_pActivationDate,''DD-MON-YYYY'')
       and TO_CHAR(vr_pExpiryDate,''DD-MON-YYYY'')
       ) And NVL(Orderdtl.Cancelled,0) = 0 And NVL(Orderdtl.PackageID,0) = 0;';
    end if;
       ord_cur is vr_SQL; +<----------query assigned to a cursor variable+
    ord_rec ord_cur%ROWTYPE;
   if not ord_cur%ISOPEN then
        open ord_cur;
   end if;
    loop
    fetch ord_cur into ord_rec;
    exit when ord_cur%NOTFOUND;So currently we are stuck with this problem.
Any solution would be of great help..
thank you

You need to consider using ref cursors for such things (sys_refcursor) e.g.

3 end;

6        open cur_o for select empno, ename from emp;
7      elsif p_no =2 then
8        open cur_o for select deptno, dname from dept;
9      else
10        RAISE myexc;

13      when myexc then

Problems in creation of workbook using Change query local view.

Hi Experts,
I have created a Multiprovider by using union of two infocubes and created a Query based on Multiprovider. I want to restrict one infocube in Change Query local view for creating new workbooks. In Query global view we drag and drop the Infocube under Filters, but in the Query local view Filter panel is in disable mode. (My requirement is to create the workbooks using change query local view only)
How can I restrict the one Infocube values in the workbooks by using Change query local view?
Thanks in advance.
Venkat.

Hi Venkat Prasad
As you told that the query is on multi provider and the view is not allowing to declare/define filter value
Just drag the infoprovider info object avilable under packet dimension to rows and right click on it restrict by selecting the name of the info provider when u right click it will show you the option of restrict once u click on it,it will takes to u a pop up where you can able to see the name of info providers and you specify according to it and finally in the display of results if you dont want to to display the info provider name then just right click on the 0infoprovider object under rows go to properties then choose hide option under display.
Hope its clear a little..!
Thanks

How to pass the feild names of a select query dynamically?

Hi
How can we pass the feilds names in select query dynamically?
For example in my selection screen i wil be giving the table name, and feilds in that table.....
those feilds should be taken in my select query...
instead of
PARAMETERS : tab_name TYPE ddobjname .
SELECT *
    FROM (tab_name)
    INTO TABLE <newtab>
   UP TO 25 ROWS.
parametrs : feild1 like-------
                 feild2----
i need select feild1 feild2 feild3    FROM (tab_name)
    INTO TABLE <newtab>
   UP TO 25 ROWS.

by the way, contrary to popular belief there is no performance problem when using
SELECT * FROM dbtab INTO CORRESPONDING FIELDS OF TABLE itab WHERE ...
as long as the structure of itab contains only the required fields.
I ran some benchmarks against this and above construct is maybe 0.1% slower (Oracle 10g) than a
SELECT f1 f2 f3 f4 ... FROM dbtab INTO TABLE itab WHERE ...
but is saves you from maintaining a potentially very long field list in your code. So when you need additional fields later on, you just add them to the DDIC structure or type definition and that's it.
Maybe something you want to factor in here.
Cheers
Thomas
