How to count the length of a collection in JSTL?
Hi ,Everyone.
I want to count the length of a collection in JSTL.
For example:
<c:out value="${length(ownerList)}" />
the program compile wrong. Is length function supported in JSTL?
Thanks in advance!
Use:
<c:out value="${fn:length(ownerList)}"/>You'll have to include the functions taglib to use the function:
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>

How to get the length of apex_item in javascript?
Hello all
I am having a tabular report using apex_item, I want to know how can i get the length of the item in javascript? like we do in pl/sql using apex_application.g_f01.count().
and one more thing, when I go to certain page, tab of that page is getting disabled, what should I do to make tab available always whether I am on that page or on any other page.
Thanks
TauceefHi Oli
Thanks for replying, In my first question actually I am validating the report values in javascript for that I need the length of the apex_item to run the loop that many times.
Like we can get the length using apex_application.g_f011.count in pl/sql process how to get the length in the javascript, is there a way for that?
I got the answer for the second question, this is the one.
Thanks

How to find the length of the resultset
how to find the length of the resultset
(Doing a select count as somebody suggested is nota
good solution, as the count can change betweenyour
count query and your real query.)And the number of rows can't change between getting
the last one and doing the actual work?I don't think so. Once you've got the ResultSet, I don't think it will change under you, unless you explicitly set it to SCROLL_SENSITIVE.
I could be mistaken though. -

Hi!
How to count the no of digits entered in the Numberic Field and print the content of Numberic Field.
Thanks.Hi Venkat,
To check the number of digits, just convert it to a string and use the length() method. to get the number of characters. However, I am not getting your second point of printing the number?
Kindly explain in detail.

How to get the length in bytes of a string
My string has both latin (1 byte) and chinese (2 bytes).
My program is in unicode system.
How to measure the length in bytes of the string?
the xlen function does not work.Hello,
parameters : p_str type string.
data : len type i.
len = strlen( p_str ).
write : / len.
With Regards,

Hi BSV, your code return the number of characters not bytes.
Remember chinese character in US are encoded with 2 bytes.
And my string contain both latin and chinese characters.

How to count the number of rows in a resultser object?
hi there
how to count the number of rows in a resultser object which may contains millions of rows? besides using a while loop? thanksYou don't, you execute a query whose result is the record count of those records that match the search and then you execute the actual query to create your record set. Typically you do
select count(id) from YourTable where [filter]
from the resulting ResultSet do
int res.getInt(1);
which gives you the count and then
select id from YourTable where [filter]
to produce the actual result set.
in the second query the id part can be substituted with the actual fields you want. -

How to Increase the Length of Condition table in OV20
While creating a condition table in T.code OV20 if fields length is more that 50 bytes table is not getting generated.it gives error as Too Many Fields Selected(More than 50 Bytes).
Actually i need to create a tabel with Basic Material(WRKST) which has length of 48 bytes.
Is there a solution on how to increase the length so that error is avoided.
There is no such error occuring while crating condition table in V/03Hi,
You can try to use the type string:
form like zscr_data_hdr-form,
werks like zscr_data_hdr-werks,
matnr like zscr_data_hdr-matnr,
verid like zscr_data_hdr-verid,
lot like zscr_data_hdr-lot,
lot_qty like zscr_data_hdr-lot_qty,
udate like zscr_data_hdr-udate,
utime like zscr_data_hdr-utime,
zuser like zscr_data_hdr-zuser,
processed like zscr_data_hdr-processed,
defect like zscr_defect_data-defect,
vornr like zscr_route_data-vornr,
fieldxx type string,
dayst like zscr_data_hdr-dayst,
end of t_data.
So you can save you informations of every fld<n> concatenating their values into fieldxx.

In this fld1 to fld135 are defined in internal table.
But if the number of fields are more than 135 then the program is going to short dump.
Some times fld1 to fid170 or more fields will be there in my internal table.
Please suggest me how to make my requirement dynamic and display this data fetched into this internal table onto a .XLS file in the presentation server ?Hi

How to restrict the length of the input?
Hi all, could any one tell me how to restrict the length of the input string? My SOA Suite is 10.1.3.1
I tried the following; getting an error.
<element name="RestrictLengthProcessRequest">
<simpleType name="SSN">
<restriction base="string">
<length value="10"/>
</restriction>
</simpleType>
where RestrictLengthProcessRequest is the message name of the corresponding .wsdl and SSN is the input whose length is to be restricted.
The error is : 'Attribute name not defined on element simpleType'
Thanks in advance.
Edited by: user11275112 on Aug 27, 2009 11:44 PMHi swathi,
For this you have to create a simple data type. No need of writing a code.
Go to Dictionaries -> Local Dictionary -> Data Type - > Simple Type - > Right click and "Create Simple Type".
Here you should create a Simple type with String as built-in Type. Here you will also see the Length Constraints option.
Set the value of maximum length and minimum length. In your case set the value of maximum length to 10. At runtime this will not allow the user to enter more than 10 characters.
Now create an attribute and bind it to this newly created simple type. Bind the value of the input field with this particular attribute.
Regards

How to increase the length of the Info object
Hi All
Any one have idea about how to increse the length of the Info object Char(beyond 60). Can you please explain me in detail we are using BI7.0.
Thanks
VaniHello Vani,
You cannot increase the length of an info-object beyond 60 chars.However if you want to store a characteristics data with more than length 60, then you may create separate info-objects
for example: if you need to store 'notes' which might have length more than 60,
then you may create info-objects like notes 1/3 ---store first 60 chars.
notes 2/3 --- store next 60 characters and so on.
Thanx

A simple question. How to calculate the length of a string?
Thanks!Hi Wuyia Nata,
As everyone has suggested you search the forum before posting a question, i guess for basic questions u never have to post a question, you will get the answer in your search. Anyways see the code below for string lenght.
Data:
w_string type string,
w_lenght type i.
w_string = 'vhdskbvsdkbvdsvnsknvs'.
w_lenght = strlen( w_string ).
Write:
w_lenght.
With luck,
