How to get the size/maximum length of an varchar?
Hello,
Is there a (Oracle-)function determining the size/max.length on an varchar2-column/-variable in PL/SQL? E.g. like SIZEOF(myVar), SIZE(myVar) in other languages...
Regards,
Martin

Karthick,
Your solution is interesting. I'm thinking of writing my own function (but it handles table's columns only - no PL/SQL-declared variables of varchar-type)...
It seems there's no Oracle-character-function available returning such numeric values....
...could be an enhancement for further releases :-) ?!In my experience everytime you need to think about defined length you have a logical problem in you database design.
Of Cause you define how large a column value could be ant set those values accordingly.
But since you define that, your also implement it in the code.
Everytime the code needs to look at columns sizes or length restrictions, something is wrong.
Maybe tell us the whole picture and it would be possible to find other ways of improvement.
Also remember that you can declare variables with a column type in pl/sql.

How to get the size of partition?
The following SQL will get the rows of the fact table & aggregation. But how to get the size (MB) of the partition. select * from $system.discover_partition_stat That should be doable, because in BIDS, we can see the size of a partition, but from which
view we can do that?This is the best bet you have SELECT * FROM SystemRestrictSchema($system.discover_partition_stat ,DATABASE_NAME = 'Adventure Works DW' ,CUBE_NAME = 'Adventure Works' ,MEASURE_GROUP_NAME = 'Internet Sales' ,PARTITION_NAME = 'Internet_Sales_2003') Refer

How to get the size of a hard disk?
Hi,
As above, how to get the size of a hard disk by using Java.
Thanks you!
AlexI would be interested in the answer of this question, too.
In core Java there is no way to find it out in a platform independent manner because of the hardware abstraction of the VM. So my only idea is to write a native library for doing this and colling it via JNI -

How to get the size of the file
Hi All,
I want to get the size of the file in terms of bytes. I used the following code it returns the value in long how can get it in bytes
import java.io.File;
public class ServerBackupCheck {
public static void main(String args[]){
File f = new File("C:/Program Files/Apache Software Foundation/Tomcat 5.5");
System.out.println(f.isDirectory());
System.out.println(f.getTotalSpace());
output:
true
20964163584
regards,
Maheshwaran Devarajif it is a folder you can use this recursive algorithm
public static long recurse(File f) throws IOException
long bytes = 0;
File files[] = f.listFiles();
for(int i =0 ;i<files.length;i++)
File file = files ;
if(file.isFile())
FileInputStream fis = new FileInputStream(file);
byte[] by = new byte[fis.available()];
fis.read(by);
bytes = bytes + by.length;
if(file.isDirectory())
bytes = bytes + recurse(file);
return bytes;
System.out.println(recurse(f)); gives you the total bytes....

Hi
I want to know the size of the file from Java. ie If i have 10 lines in that file each of 15 characters
then 10 *2*10=200Bytes is the size. How will i get this?
More over, if i am reading the 4 the line, how will get the info that I have read 3 lines =3*2*10= 60 bytes so far?
Regards
SriramThis is from the JavaDocs on java.io.File
length
public long length()
Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.
Returns:
The length, in bytes, of the file denoted by this abstract pathname, or 0L if the file does not exist
Any of the read methods (except readLine()) on the many stream objects return the number of bytes read, simply accumulate these returns to know how many bytes have been read.

How to get the size of the cuurrent illustration
Sorry, I made a mistake before this one. The questios is this: can anybody tell me how can I get the size of the current illustration, (as oposed to the page size) in points. Something like 120 points wide and 87 points High?. What function do I need to call?
From AI Function reference (included with CS2 SDK):
AIDocumentSetup setup;
error = sDocument->GetDocumentSetup(&setup);
if (error) goto processError;
writeDocumentSetup( &setup );
The AIDocumentSetup record returns the following information:
typedef struct {
AIReal width, height;
AIBoolean showPlacedImages;
short pageView;
AIReal outputResolution;
AIBoolean splitLongPaths;
AIBoolean useDefaultScreen;
AIBoolean compatibleGradients;

How to get the size of JSP html output?
Hi,
Is there a JSP method to get the size of JSP HTML output.
e.g. I would like to print the size of the JSP e.g.
Size of this page is <%=pageContext.getPageSize()%> Kb ???
Any ideas? Thanks.
George
Edited by: googchro on Jan 5, 2010 4:45 PMWould you like to print "the size of this page is..." before or after you calculate the size of the page.
Because adding that bit of text to the page will make the page bigger...
Doing it in java, the best approach would probably to have a filter counting the number of bytes that gets sent to the writer/output stream.
A client side tool measuring the amount of bytes received would probably be easier though.
You can always look at the Content-length header sent with a response. Though you normally don't have access to that on the java/jsp side, as it is sent by the container.
cheers,

How to get the size of the test put in a JPasswordField ?
I've checked all the methods that may allow me to know the size
of the text in a JPasswordField.
I tested getCaretPosition() , getSelectedEnd()
and they don't satisfy me : they give the current position of the cursor
and not the size of the text typed. The only safe method is the use
of the method getText() which is deprecated, so that i can get the
size of the resulting String.
Is there a method that allow to know the size of a char arrays ?
Any help will be welcome, thanks.JPasswordFieldObj.getPassword().length;the length variable isn't visible in the forte visual parameters.
thanks a lot, it saved me a lot of time and let me keep the
getPassword() secure.
Sorry, don't have more duke dollars, but you should have get some for this. -
How to get the size of the blob file uploaded ?
Hi ,
Is there anyway to get the size of the file i have uploaded to a blob type attribute ?
What i can see is that when we upload a file in contributor UI ,once the file is uploaded successfully and if we hover on it , it will show the filename , type and size of the uploaded file .
From where can we get that details so that we can reuse these details in our code ?
Thanks and Regards,
PraveenA filter is a sensible solution, or you can get it in a roundabout way like this for example if you have the blobid (this is paraphrased from OpenMarket/Gator/AttributeTypes/IMAGEPICKERShowImages.jsp):
<ics:sql sql='<%="select urldata,filevalue from MungoBlobs where id=" + ics.GetVar("blobid")%>' listname="blobdata" table="MungoBlobs" />
<ics:listget listname="blobdata" fieldname="urldata" output="urldata" />
<ics:setvar name="blobpath" value='<%=ics.GetProperty("cc.urlattrpath", "gator.ini", true) + ics.GetVar("urldata")%>' />
<%
File blobFile = new File(ics.GetVar("blobpath"));
long length = blobFile.length();
%>
