Hi,
Single quote you have to put at the begining and the end of a string.

Sorry ..
Here is my full codeThat's still not a complete script. You need to post CREATE TABLE and INSERT statements for any tables it references, or else modify it so that it uses commonly available tables, such as those in the scott schema.
CREATE OR REPLACE
FUNCTION fn_test(
v_id IN VARCHAR2)
RETURN VARCHAR2
IS
v_final_string VARCHAR2(4000) := '';
BEGIN
FOR temp IN
(SELECT name FROM test_name WHERE id=v_id

DBMS_OUTPUT.put_line ('temp=' || temp.name );
IF LENGTH(v_final_string) < 3800 THEN
SELECT nvl2(v_final_string,v_final_string
||',' ,v_final_string)
|| temp.name
INTO v_final_string
FROM DUAL;
/* v_final_string:= NVL2(v_final_string,v_final_string|| ',',v_final_string) || temp.name; */
DBMS_OUTPUT.put_line ('v_final_string=' || v_final_string );
ELSE
EXIT;
END IF;
END LOOP;
RETURN NVL(v_final_string,'No string Available');
END;
/Here's how you can modify it, using the second approach I suggested earlier:

SHOW ERRORSSince there are 2 ways to exit the loop, I moved LTRIM outside the loop.
If you're using Oracle 11.2, the built-in function LISTAGG will be faster, if not quite as convenient.
Even in versions 9.1 through 11.1, you might consider not using PL/SQL for this. See this page for several string aggregation techniques.

How to convert String date to java sql date

I have an html form for entering the Date on retreving that value in a java servlet i get it as a string i want to convert that date to SQL date format so that i could use setDate() method of the java.sql.Date class to update the date value in the database.
i used the following way but i need the code without using the deprecated ones.
String delDate = (String)p_Request.getParameter("deleteDate");
[b]java.util.Date utilDate = new java.util.Date(delDate);
java.sql.Date deleteDate = new java.sql.Date(utilDate.getTime());
custCode = (String)p_Request.getValue("custCode");
thanx in advance.

How to embed string into rectangle?

Hi all.
I have a rectangular area to draw the string, but the string can be wider than the rectangle it should fit. How to draw truncated string? For example:
public void paintComponent(Graphics g) {
          String s = new String("This is a very long string");
          int x = 0;
          int y = 0;
          int rectWidth = 20;
          int rectHeight = 10;
          Rectangle r = new Rectangle(x, y, rectWidth, rectHeight);
          int strWidth = g.getFontMetrics().stringWidth(s);
          if (strWidth > rectWidth) {
               System.err.println("How to do that?");
          } else {
               g.drawString(s, x, y);
     }Thank you in advance.

If what you want is for your clipped string to display the "..." just like JLabel does, here is an algorythm that you can use:
1- If the font metrics tells you that your string is going to get clipped, start removing chars from the end
2- add "..." to the shortened string.
3- if that string now fits, done
4- else goto 1

How to get prepared string before sending to sql

Hi
I want the prepared string before sending to Sql (After substitution and setXXX), is it possible to do this? if yes, how ?
PreparedStatement ps = cn.prepareStatement("select * from table1 where name= ''?'' ");
ps.setString(1, "mytable")
<-- I want the prepared string before sending to Sql (After substitution and setXXX) -->
ResultSet rs = ps.executeQuery();
Thanks
Ali

As I mentioned, I want Sql Text before execution
n (getting resultSet), and after whole of setXXXs,No way, I believe.
I have tried in many ways, let me put down my work.
String query = "'Select * from dept where deptno=?'";
System.out.println("Before : "+query);
PreparedStatement ps = con.prepareStatement("select "+query+",? from Dual");
ps.setInt(1,50);
ResultSet rs = ps.executeQuery();
if(rs.next()) {
System.out.println("After : "+rs.getString(1));
ps.close();
con.close();I have tried in these lines, to capture the sql query, but it is failing at execution and the exception is 'bind variable not found'. So, I think you need to implement your own class to construct this query. Getting the details from DatabaseMetadata to see how the driver's setter methods works and you can use the same logic in your custom class.
Good luck.

Error SQL70015: Error validating element [dbo].[GetDocument]: Deprecated feature 'String literals as column aliases' is not supported

Using MS SQL Management Studio 2012 attempting to export (from GoDaddy) a .bacpac database for import to Azure and get the error message listed in the Title (String literals as column aliases is not supported on SQL Azure). There was a discussion of this
problem in mid-2013, but it ended with saying that this was a bug with Azure validation, but had been fixed and did not require rewriting of databases. Anyone with a clue how to successfully export/import around this?

Hello,
A string enclosed in quotation marks used as a column alias for an expression in a SELECT list is not support in Windows Azure SQL database. Please use "expression [AS] column_alias" instead of " 'string_alias' = expression ".
In your case, you can try to create an application with in SSDT and use Schema Compare to filter out and fixed incompatible objects, and then deploy the database to Windows Azure SQL database.

How to pass a structure in PL/SQL external proc.

This is for educational purpose only. I am trying to implement kernel32.dll and shell32.dll in PL/SQL using external proc. Everything is working fine, except When there is a structure in OUT parameter.

TNS for 32-bit Windows: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - ProductionI have set up the listner.ora and tnsnames.ora and written a package called dbms_kernel32sb.
There are 9 program units.
1. CreateFile -- working fine
2. CloseFile -- working fine
3. GetSize -- working fine
4. FindFirstFile -- NOT working, because one OUT parameter has the structure type WIN32_FIND_DATA.
5. GetFileTime -- NOT working, because one OUT parameter has the structure type FILETIME
6. GetDiskFreeSpace -- working fine
7. GetDriveType -- working fine.
8. GetLastError -- working fine
9. ExecuteCommand -- working fine.

So, I have noticed that, Where ever a STRUCTURE is involved in external routine, there is a problem. I want to know, How to implement functions with STRUCTURE as OUT parameter.
Forgot to mention: This is my FILETIME object which corresponds to FILETIME structure of win32.The problem is that this passes the parameter by reference and not value. In a vanilla C/C++/Delphi program, you will create a variable of that struct and then pass a long pointer to that variable when making the API call. That pointer will be dereferenced and the memory it points to, populated. This is not a problem as the underlying DLL you call that does this, uses your process's data segment.
Extproc is different. In order to protect the integrity of the database server process, an external call is done by a "proxy" process. It acts as the interface between your PL/SQL code and the actual external call.
In this case, this "proxy" process will be doing the implicit LoadLibrary() call to load kernel32.dll interface - and the DLL will expect to dereference and access this process's memory struct to populate it. This "proxy" process in turn needs to know that despite it calling the interface by reference, it needs to return that parameter to PL/SQL by value - as your PL/SQL code cannot dereference a pointer passed back by that "proxy" process and access its memory to gain access to that struct.
In basic terms - that argument is a 32 bit number containing a pointer. That is what the "proxy" process needs to pass to the interface call. Your code is passing a struct and not a pointer, right?
And that is the basic problem I believe. How to address this.. not sure. You can have your own DLL as interface that does not use pointers but expect arguments to be passed by value. But this will suck as you then need to include a custom DLL to deploy and have PL/SQL call that, instead of simply accessing and calling the native kernel interface.
Doubt that many Win32 programmers with OCI (Oracle Call Interface) frequents this forum. So perhaps this is not the best place to ask. I would be hitting Metalink (support.oracle.com) search function in your sho3s though as there should be support notes dealing with this subject matter.

How to delete number (00) in a SQL Server column ?

how to delete number (00) in a SQL Server column ?
example :
column : Births before   Births
  after
                   199900
        1999
         198200
     1982
                   200400
    2004
help query

You use REPLACE function to selectively replace text inside a string in SQL Server. The REPLACE function is easy to use and very handy with an UPDATE statement.
SELECT Replace(births, '00', '')
or
update .....
Also you can use STUFF()
This function can be used for delete a certain length of the string and insert a new string in the deleted place.
Select STUFF ('199900', 5, 2, '')
--result 1900,1982,....

How to embed information in an image

im trying to add text to an image without it displaying on the image. basically i need to know how to embed text in a jpeg. currently im trying to send information by adding data to the least significant bit but to no avail.
any help will be much appreciated. thanks.

heres how it went kevin
i loaded an image. the image data is a cluster. by using unbundle by name i can separate it to components. the rgb info on the data is located in "image" in the unbundle. send this to a decimate...extracting 3 values. these three values are the rg and b components of the image. the rest is as i mentioned above. take either r,g or b value (doesnt matter which color you encode the data to) do a string to byte array. send through an empty for loop with the string length wired to the count...making the loop run as many times as the number of characters ur embedding. the result is sent to replace array subset (with index 0) and then interleaved with the remaining 2 channels to form back the composite rgb...send back to a bundle by name with the characteristics coming from the original image data. draw flattened pixmap and output (this displayed pic with encoded data...no difference!!). extraction is a reverse process but inside the forloop place index array with index zero. loop count once again wired to original string length. output from the for loop goes to a byte to string and string indicator! let me know if it works for you
dee.

How to connect labviewv database toolkit to SQL CE server

Dear sir,
i am using labview 8.2.1 and Database Connectivity 8.2.i need same simple concept of how to connect LV database toolkit to SQL CE Server.

When opening the database connection, you will need to provide either a connection string, or a path to a UDL (which will contain a conenction string). The easiest way to get a connection string is to go to (no I am not kidding) www.ConnectionStrings.com. Once there you enter the type of DBMS you are trying to connect to, and the system will list connection strings that you can use based on the drivers that you're using.
How much experience do you have with LV and/or databases?
Mike...

How to embed the webcontent in Email

Hi Everyone,
would you kindly let me know how to embed the webcontent in emails.
Thank you.

Actually, i believe it is possible if you encoded the
image file as a String, but still, why on earth you
want to do it?!Doesn't have to be a string. You could hardcode an array of bytes, and create an image from that.
IIRC that was a clumsy but useful technique prior to the introduction of jar files.
I may be misremembering. Check the docs to confirm...
