Check input values are available in Hex
how to check input values are available between 0x0000000000000001 to
0xFFFFFFFFFFFFFFFE
i am using following code. but error will come
public boolean hexCheck16(String hex)
String hex_min = "0x0000000000000001";
String hex_max = "0xFFFFFFFFFFFFFFFE";
int min1 = Integer.parseInt(hex_min.substring(2).toString(),16);
int max2 = Integer.parseInt(hex_max.substring(2).toString(),16);
int num = Integer.parseInt(hex.toString(), 16);
if(num >= min1 & num <= max2)
return true;
else
return false;
Error is : java.lang.NumberFormatException: For input string: "FFFFFFFFFFFFFFFE"
how to solve?
Use BigInteger (and lose the "0x").

Previously, the "Check for updates" option is found under the Help menu. In Firefox 4, I cannot find this option; how will we be able to check if there are available updates?

UDF Required for checking input value.
Hi,
I'm in need of an UDF for checking the input value and pass constant based on that.
Requirement.
We are having 1 field on the source side which need to be checked.
If the first character of the input is alphabet (No case sensitive)
then pass a constant "X" to the output field.
Other wise donot create that particular element.
Example : If INPUT = A12345 then OUTPUT = X
If INPUT = 12345D then OUTPUT element must not be created.
Regards,
Swapnause the following code in a udf and then pass the result to createIf standard function to help you with the requirement.
String chkValue = input.subString(0,1);
String flag = "false";
if ((chkValue >= 'A' && chkValue <= 'Z') || (chkValue >= 'a' && chkValue <= 'z')) {
flag = "true";
return flag;
else
{return flag;} -
I need to check if the field X in the query is 0.00. If so, then display "HELLO" in the table field Y.
Thanks,Kevin,
you could add an additional field to the output port of the query (for table field Y), and calculate its value dynamically by using the formula -->if(@x == 0.0, 'Hello','Others')

SQL function to retrieve records only if all the values are available.
Hi,
I have a sales table on which i run a parameterized query.
We pass a few week IDs to retrieve store sales.
I need to retrieve only those stores that has sales in all the week IDs passed.
If i use the in operator, i am getting the store data even if there is sales for only one week.
Is there a function in oracle to do this?
Thanks,
Sharan.Hi, Sharan,
Here's how you could use the analytic COUNT function:
WITH got_week_cnt AS
select week_id, store_id, prod_desc, sales_units_raw, sales_value_raw
, COUNT (DISTINCT week_id) OVER (PARTITION BY store_id) AS week_cnt
from sales_store_dwh
where week_id in (&&Week_ID_CSV)
select week_id, store_id, prod_desc, sales_units_raw, sales_value_raw
FROM got_week_cnt
WHERE week_cnt = 1 + LENGTH ('&&Week_ID_CSV')
- LENGTH (REPLACE ('&&Week_ID_CSV', ','))
;Notice that the sub-query got_week_cnt is just your original query, with the COUNT function added.
You didn't post your tables or results, so I can't test it.
You didn't say what version you're using, so I made a conservative guess (Oracle 9 or higher). In Oracle 11, there's a simpler way to find the number of weeks passed. -
Input values in the result area
Hi Bw gurus,
Could you plz tell me to eliminate the Input values displayed between the Navigation block and the Result area.
I mean if we give some input range in the variable screen the range(Input)values are displayed in the Result area.Also if we give some 1000 multiple single values in the variable selection screen after executing it displyed
1000 input values in the result.
I need to elimeinate this.so how can i do this.
the requirement is very urgent.

Rambo.Hi Rambo,
Open query in BEx Analyzer, it'll be embedded into a workbook.
Use Layout/Dasplay text elements icon or menu path.
There you'll see the option to show variables. Don't use it and variable's values shouldn't show up!
And don't use show all.
Best regards,
Eugene

Authority Check on Value within standard transactions
Hi Guruus !
Let's state that a user is allowed and has the profile/role to access a given transaction, let's say MI01, but ME21N will do to !
Now, actually, users are supposed an that project to be authorized on certain Storage Location (LGORT). How can we set the system so that they can input Storage Location Value they're not authorized on ?
Is there a standard way to do that ? Or do we have to use some Exit/BAdI in every transactions to check if the input value are correct ?
I also have the same concern about report transaction, such as ME2K (for example), while executinf (F8) them.
Thx in advance for your clue,
N HHi,
This is a BASIS Issue. Get in touch of your BASIS guy and let him know about anything that you are doing.
I believe a Standard Authority Object should serve your purpose...Look into the Txn Code SU21 and talk 2 your BASIS Guy.
Else You can create a Z Authority Object to achieve this Functionality.
Create an authorization class with SU21 and then create authorization object under it which correspond
to the your desired tcode. The authorization field is ACTVT. Then go to SE93 and attach the object with the Tocde.
you have to associate the Authority Object to a role in PFCG.
Regarding Report Txn, You need to do the same... -

Xcelsius -webservice-input values
Hi Experts,
i have a problem regarding xcelsius dashboard .
i have done a connection between R/3 and Xcelsius using FM and showing the result in the BSP page. it is working.
Now i created dashboard, using web service
here input values are TOLOG, Username and Compif, all are selected single cell on excel.In each input value filed i have a selektion possibility als drop down. By running the dashboard it is not working.
How i can give the input value by running the dashboard so that the selected value appear?
It should work like Webservice test
Thank you in advanceHi
No there isn't. You have to use additional components like a Spreadsheet or Grid component, or even individual Labels to get the values 'onto' the graphic.

How to check the value from user input in database or not?
Hello;
I want to check the value of user input from JtextFiled in my database or not.
If it is in database, then i will pop up a window to tell us, otherwise, it will tell us it is not in database.
My problem is my code do not work properly, sometimes, it tell me correct information, sometime it tell wrong information.
Could anyone help,please.Thanks
The following code is for check whether the value in database or not, and pop up a window to tell us.
while( rs.next()) {
System.out.println("i am testing");

flag=1; //I set a flag to check whether the id in database or not
break;
System.out.println("falg" + flag);

}You may have working code now, but the code you posted is horrible and I'm going to tell you a much much much better approach for the JDBC part. (You should probably isolate your database code from your user interface code as well, but I'm skipping over that structural problem...)
Do this instead:
public void getData(String a){
PreparedStatement p;
String strQuery = "select count(*) the_count from customer where id = ?";
try {
//create a prepared statement object to execute sql statements, it's better, faster, safer
p = c.prepareStatement(strQuery);
// bind the parameter value to the "?"
p.setInt(1, Integer.parseInt(a) );
//execute the query
ResultSet rs = p.executeQuery( );
// if the query doesn't throw an exception, it will have exactly one row
rs.next();
System.out.println("i am testing");
if (rs.getInt("the_count") > 0 ) {
// it's there, do what you need to...
else
JOptionPane.showMessageDialog(null,"I could not find the value");
catch (SQLException e) {
// JOptionPane.showMessageDialog(null,"You may enter wrong id");
// if you get an exception, something is really wrong, and it's NOT user error
// always, always, ALWAYS close JDBC resources in a finally block
finally
p.close();
}First, this is simpler and easier to read.
Second, this retrieves just the needed information, whether or not the id is in the database. Your way will get much much slower as more data goes into the database. My way, if there is an index on the id column, more data doesn;t slow it down very much.
I've also left some important points in comments.
No guarantees that there isn't a dumb typo in there; I didn't actually compile it, much less test it. It's at least close though... -
In iTunes on my windows 7 PC, in the Edit/Preferences dropdown window,some of the tab windows are not large enough to see all options that are available. The borders of the window cannot be draged larger. As a result, I can not uncheck or check some box's on several of the preferences pages. The Apple people at the store did not help. I have lownloaded the latest version of iTunes and this is still an issue. HELP.
Is there really nobody else with this problem? Really?

Table Parameter Values Are Input To RFC?
Hi,
My Requirement is Table Parameter Values are Input RFC.
We have Table Parameter With Project ID Column and Multiple Rows.
User Need To Enter Project id's in Table And Submit.The Result can be displayed.
In My Scenario User Need to enter the values in table.
I Developed Webdynpro Application and Deployed.
When i am trying to enter values into a table,table is not taking values.
Because in My Requirment is the user enter morethan one project id in table.
Thanks
SubbaRao ChintaHi,
Can you please explain more clearly that what is the meaning of "Table not taking values"?
Did you take the ColumnCellEditor(inputfield) for table column as input field.
For example, You need to create a value node as below
ProjectIdsNode (Value node with cardinality 0..n & selection 0...n)
---> ProjectId (Attribute)
And bind this ProjectIds node to table UI element. And bind ProjectId attribute to ColumnCellEditors(inputfield) value property.
Now in submit action loop though this node and get all the values entered in ProjectId attribute.
And set all these values into input of your RFC while executing to store in backend.

Variable input values in the query are displayed wrong
Hi experts,
I executed a report and in the variable input screen it asks for a key date and company code.
We entered key date and company code and executed the report.
We want to take a print out of the output. But the variables which we entered in the variable screens are
dispalying wrong. i.e if we have entered company code as gsml and key date as 01.01.2008.
In the report output I am getting as:
Company code: gsml
Keydate: #..27-11-4745
But keydate should be displayed as 01.01.2008
How to solve this ?
Regards,
Nishuv.Nishuv,
Please follow below steps:
1. Open query through Bex - Query Designer
2. Beneath the Rows Area( where you actually drag in charactertistics), you'll be finding two tabs Filter and Rows/Columns
3. Click on Filter Tab
4.You'll be navigated to a window, there you can trace two Workareas
a. Characteristic Restrictions: Where drag in the relevant Prompts/Input Variables
b. Default Vaules
5.First, Drag the required promts/Input Variables in Characteristics Restrictions.
6.Click on the varible which was dragged in Characteristic Restriction area and drop it into default values area.
7.Now you'll have visibility of variable in two regions, Characteristics and Default Values.
8. Save and Execute the Query
