How to get value by running in code behind?
Hi all,
i am running one stored procedure which return value.
i am calling that stored procedure like this.
Dim retvalue As Integer
dtformat.ShortDatePattern = "MM/dd/yyyy"
Dim YourDate As DateTime = Convert.ToDateTime(dt, dtformat).ToString("MMM/dd/yyyy")
Dim hsh As New Hashtable
objDataTier.OpenDbConnection()
con1.Open()
Dim oc As New OracleCommand("spSelectStartDay")
oc.CommandType = CommandType.StoredProcedure
oc.Parameters.Add("v_pidate", OracleType.DateTime).Value = dt
retvalue = oc.Parameters("v_poRetval").Value.ToString()
but not getting value in retvalue variable?
how to get the value in that.
my stored procedure is here.
create or replace
Procedure spSelectStartDay
v_pidate IN DATE DEFAULT NULL ,
v_poRetVal OUT NUMBER
AS
v_dpart NUMBER(10,0);
v_date DATE;
v_startweek NUMBER(10,0);
BEGIN
v_dpart := TO_Char(v_pidate,'DD') ;
v_dpart := v_dpart - 1 ;
v_date := Trunc(Trunc(v_pidate, 'MM')+1,'MM');
v_startweek := TO_CHAR(to_date(v_date, 'dd-MM-yy'), 'd');
v_poRetVal := v_startweek ;
RETURN;
END;
thanks
You need to add both parameters. You should create the parameter, then specify a direction. In C# (taken from a script that executes an anonymous block, but will work for your purposes)
using (OracleConnection oCon = new OracleConnection(_connectionString))
oCon.Open();
using (OracleCommand oCmd = new OracleCommand())
oCmd.Connection = oCon;
oCmd.CommandType = CommandType.Text;
oCmd.CommandText = sql;
oCmd.BindByName = true;
OracleParameter opS = new OracleParameter("p_s", OracleDbType.Varchar2, 100, s, ParameterDirection.Input);
OracleParameter opC = new OracleParameter("p_c", OracleDbType.Int32, c, ParameterDirection.Input);
OracleParameter opA = new OracleParameter("v_a", OracleDbType.BinaryDouble, ParameterDirection.InputOutput);
oCmd.Parameters.Add(opS);
oCmd.Parameters.Add(opC);
oCmd.Parameters.Add(opA);
oCmd.ExecuteNonQuery();
a = double.Parse(oCmd.Parameters["v_a"].Value.ToString()); // note there are better ways to do this... it's quick and dirty to parse the string value.

How to get value of URL parameter
Hi,
If an ABAP Web Dynpro URL looks like this: http://<server>:<port>/sap/bc/webdynpro/sap/zny_test1?sap-client=100&sap-language=EN, how to get value of the URL parameter sap-client at runtime in the application?
Thanks,
NancyThe framework currently strips all the framework specific params.
Perhaps the will be made available in a future release. Thomas, any comments ?
However, I dont understand the requriement to know the sap-client URL value.
If your code is running, a user has successfully connected to system a therefore he has a session open and this session is associated with exactly 1 client at any point in time.
See SYSTEM VARAIBLE SY-MANDT.
this represents the client in which the users session is running and negates the need to see
sap-client URL value.

How to get value of html combo box (i.e select) in jsp?
Hello,
I was just wondering how to get value of html combo box in jsp page. My code for combo box is:
<select name="combo" size="1">
<%
List<Project> projects = mgr.getProjects();
for(Project project : projects){
%>
<option value="<%= project.getId()%>"><%= project.getName()%></option>
<%
%>
</select>
I thought combo.value might give me the value, but it throws exception.
Any help is appreciated.
Thanks.The combo does not exists in Java, but only in HTML. You have to submit the form containing the combo and then use request.getParameter("combo") to get it's value ;-)

How to get Value of a item of first record when current record is second
How to get Value of a item of first record when current record is second in Form6i ?
get_item_instance_property dose not allow to get value.Gerd,
You're right, there are several other triggers that must be coded, but I was responding to Steve's statement about Inserting or deleting records from the multi-record block. For the record, I use the following to manage a Record Group:
* When-New-Block-Instance - Initialize the RG
* block Post-Query - populate the RG
* When-Create-Record - add new record to RG
* When-Remove-Record - remove record from RG
* block When-New-Item-Instance - capture previous value of the item or row
* When-Validate-Item - Item specific Insert, Update, Delete of values in the RG
There are a few other places as well, but these are the minimum. It might seem like a lot of code, but then again, I don't use this solution for every multi-line block. Like all tools, you use the right tool for the job. :-)

How to get values/data stored in the database into a list-item.
how to get values/data stored in the database into a list-item.
i tried to make a list item without any values assigned to it...but i got the below error.
FRM-30191: No list items defined for required poplist.
or
FRM-32082: Invalid value for given item type.
List EMPNO
Item: EMPNO
Block: EMP
Form: MODULE5
FRM-30085: Unable to adjust form for output.
then according to some docs, i tried the the following for the trigger
when-new-form-instance
declare
rg_name varchar2(40) := 'emp_rec';
status number;
groupid recordgroup;
it_id item;
begin
it_id := Find_Item('empno');
groupid := create_group_from_query(rg_name, 'select empno from emp');
status := populate_group(groupid);
populate_list(it_id, groupid);
end;
but yet didnt work... :(
so how the heck do i get values fetched from the database table into the list item?for list items you need to values in the record group, one is the shown value and one is the returned value.
Check out the online help for the populate_list built-in.
You'll need something like select ename,ename from emp as the record group query. -

How to get value of a textfield which has been set as Renderd false.
Hi all
how to get value of a TEXTFIELD which has been set as Renderd false.
i am getting the value of this textfield from an lov but dont want to show it to the user.
getting error as:
attribute xxxx required for view object yyyyy.
pls help
naveenYou can create item inside your LOV region, set the item style to formValue. You can associate this to a View Object field. It can also act as mirror of any other text input field.
FormValue can hold the value and will not be diaplyed to user. You can read value from it controller
example
OAFormValueBean orgValue = (OAFormValueBean)webBean.findChildRecursive("OrgIdFormVal");
Or you can read it fro the VO associated with this form value. -
How to get value by jstl?
select IEPort,seqNo,IEDate,trafMode from TImport
this is in hibernate hql
List queryResult = dao.getList(session, form);so in the list is not a bean but an Object, so in the Object do not hava attribute name, i don't know how to get value by JSTL in the jsp, who can help meJSTL can figure out what the specific type of the Object is on its own. Just reference the attributes of your bean using the expression language like you would normally do. If you are uncertain print out the classname of the objects in the list like this:
${obj.class.name}where obj is an object from the list. This should print out the name of your beans if hibernate did its job properly. JSTL will know what properties these objects has even if you only pass it an Object reference. -

How to get value from Thread Run Method
I want to access a variable from the run method of a Thread externally in a class or in a method. Even though I make the variable as public /public static, I could get the value till the end of the run method only. After that it seems that scope of the variable gets lost resulting to null value in the called method/class..
How can I get the variable with the value?
This is sample code:
public class SampleSynchronisation
public static void main(String df[])
sampleThread sathr= new sampleThread();
sathr.start();
System.out.println("This is the value from the run method "+sathr.x);
/* I should get Inside the run method::: But I get only Inside */
class sampleThread extends Thread
public String x="Inside";
public void run()
x+="the run method";I think this is what you're looking for. I hold up main(), waiting for the results to be concatenated to the String.
public class sampsynch
class SampleThread extends Thread
String x = "Inside";
public void run() {
x+="the run method";
synchronized(this) {
notify();
public static void main(String[] args) throws InterruptedException {
SampleThread t = new sampsynch().new SampleThread();
t.start();
synchronized(t) {
t.wait();
System.out.println(t.x);
}
