How to get a SQL-String from a (Prepared)Statement?

Hi,
I have these three lines of code:
PreparedStatement stmt = connection.prepareStatement("select * from mytable where username= ?");
stmt.setString(1, "user");
ResultSet rs = stmt.executeQuery();
Now, I want to log all SQL-Statements with log4J.
log.info(sqlstring);
Now, I want for sqlstring something like "select * from mytable where username='user' ", i. e. the PreparedStatement-String with the parameters I set.
Is there any possibility to get this string?
I searched in class PreparedStatement, in class ResultSet, in class ResultSetMetaData, but without success.
Can anybody help me?

Use a JDBC-logging library. You can use Mimer JTrace available att http://developer.mimer.com (or http://developer.mimer.se/downloads/downloads_thank.tml?a=&id=36). It should work with any JDBC driver.

How to get an XML string from a Java Bean without wrting to a file first ?

I know we can save a Java Bean to an XML file with XMLEncoder and then read it back with XMLDecoder.
But how can I get an XML string of a Java Bean without writing to a file first ?
For instance :
My_Class A_Class = new My_Class("a",1,2,"Z", ...);
String XML_String_Of_The_Class = an XML representation of A_Class ?
Of course I can save it to a file with XMLEncoder, and read it in using XMLDecoder, then delete the file, I wonder if it is possible to skip all that and get the XML string directly ?

I think so too, but I am trying to send the object to a servlet as shown below, since I don't know how to send an object to a servlet, I can only turn it into a string and reconstruct it back to an object on the server side after receiving it :
import java.io.*;
import java.net.*;
import java.util.*;
class Servlet_Message        // Send a message to an HTTP servlet. The protocol is a GET or POST request with a URLEncoded string holding the arguments sent as name=value pairs.
public static int GET=0;
public static int POST=1;
private URL servlet;
// the URL of the servlet to send messages to
public Servlet_Message(URL servlet) { this.servlet=servlet; }
public String sendMessage(Properties args) throws IOException { return sendMessage(args,POST); }
// Send the request. Return the input stream with the response if the request succeeds.
// @param args the arguments to send to the servlet
// @param method GET or POST
// @exception IOException if error sending request
// @return the response from the servlet to this message
public String sendMessage(Properties args,int method) throws IOException
    String Input_Line;
    StringBuffer Result_Buf=new StringBuffer();
    // Set this up any way you want -- POST can be used for all calls, but request headers
    // cannot be set in JDK 1.0.2 so the query string still must be used to pass arguments.
    if (method==GET)
      URL url=new URL(servlet.toExternalForm()+"?"+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(url.openStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
    else
      URLConnection conn=servlet.openConnection();
      conn.setDoInput(true);
      conn.setDoOutput(true);
      conn.setUseCaches(false);
      // Work around a Netscape bug
      conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
      // POST the request data (html form encoded)
      DataOutputStream out=new DataOutputStream(conn.getOutputStream());
      if (args!=null && args.size()>0)
        out.writeBytes(toEncodedString(args));
//        System.out.println("ServletMessage args: "+args);
//        System.out.println("ServletMessage toEncString args: "+toEncodedString(args));
      BufferedReader in=new BufferedReader(new InputStreamReader(conn.getInputStream()));
      while ((Input_Line=in.readLine()) != null) Result_Buf.append(Input_Line+"\n");
      out.flush();
      out.close(); // ESSENTIAL for this to work!
    return Result_Buf.toString();               // Read the POST response data
// Encode the arguments in the property set as a URL-encoded string. Multiple name=value pairs are separated by ampersands.
// @return the URLEncoded string with name=value pairs
public String toEncodedString(Properties args)
    StringBuffer sb=new StringBuffer();
    if (args!=null)
      String sep="";
      Enumeration names=args.propertyNames();
      while (names.hasMoreElements())
        String name=(String)names.nextElement();
        try { sb.append(sep+URLEncoder.encode(name,"UTF-8")+"="+URLEncoder.encode(args.getProperty(name),"UTF-8")); }
//        try { sb.append(sep+URLEncoder.encode(name,"UTF-16")+"="+URLEncoder.encode(args.getProperty(name),"UTF-16")); }
        catch (UnsupportedEncodingException e) { System.out.println(e); }
        sep="&";
    return sb.toString();
}As shown above the servlet need to encode a string.
Now my question becomes :
<1> Is it possible to send an object to a servlet, if so how ? And at the receiving end how to get it back to an object ?
<2> If it can't be done, how can I be sure to encode the string in the right format to send it over to the servlet ?

How to get offending SQL-Text from OracleException

Hi,
is there a way find out the SQL which was the reason for an OracleException ?
I try to connect to a Oracle RDB database via ODP.NET and a SQLNET-driver of Oracle RDB. During the connect a "table or view not found" error fires and stops the connect. Up to now i was not able to find out which object is missing here. I tried to use the trace feature but it does not show the SQL used inside the connect...
Regards
Andreas

Hi,
you are right, this table (view) was missing. I finally sniffered the ethernet to find out what ODP.NET is doing here. I posted the solution for RDB in the thread "Info: how to prepare Oracle RDB for ODP.NET".

How to get second maximum salary from employee table(sql query)

how to get second maximum salary from employee table(sql query)

dude there is no matter of structure .........that user already said its from employee table ...............its basic table in sql and there is no need to specify the table structure
.........i think u got my point I think you are the one who didn't understand Sarma's point.
Give a man a fish and you feed him once. Teach a man how to fish and you feed him a life long.
>
and the query is
select max(sal) from emp where sal<(select max(sal)
from emp);
this will give the 2nd max salary from the emp tableBtw: You solution is bad, because it needs to scan and sort the table emp twice. And a better solution has been given already.

How to get the query values from the url in a servlet and pass them to jsp

ok..this is the situation...
all applications are routed through a login page...
so if we have a url like www.abc.com/appA/login?param1=A&param2=B , the query string must be passed onto a servlet(which is invoked before the login page is displayed)..the servlet must process the query string and then should pass all those values(as hidden values) to the login jsp..then user enters username and pswd, then there should be another servlet which takes all the hidden values of jsp and also username and pswd, authenticates the user and sends the control back to that particular application along with the hidden values...
so i need help on how to parse the query string from the original url in the servlet, pass it out to jsp, and then pass it back to the servlet and back to the original application...damnn...any help would be greatly appreciated...thanks

ok..this is the situation...Sounds like you have a bad design on your hands.
You're going to send passwords in a GET request as clear text? Nice security there.
Why not start with basic security and work your way up?

How to get all the values from the dropdown menu

How to get all the values from the dropdown menu
I need to be able to extract all values from the dropdown menu; I know how to get all those values as a string, but I need to be able to access each item; (the value in a dropdown menu will change dynamically)
How do I get number of item is selection dropdown?
How do I extract a ?name? for each value, one by one?
How do I change a selection by referring to particular index of the item in a dropdown menu?
Here is the Path to dropdown menu that I'm trying to access (form contains number of similar dropdowns)
RSWApp.om.GetElementByPath "window(index=0).form(id=""aspnetForm"" | action=""advancedsearch.aspx"" | index=0).formelement[SELECT](name=""ctl00$MainContent$hardwareBrand"" | id=""ctl00_MainContent_hardwareBrand"" | index=16)", element
Message was edited by: testtest

The findElement method allows various attributes to be used to search. Take the following two examples for the element below:
<Select Name=ProdType ID=testProd>
</Select>
I can find the element based on its name or any other attribute, I just need to specify what I am looking for. To find it by name I would do the following:
Set x = RSWApp.om.FindElement("ProdType","SELECT","Name")
If I want to search by id I could do the following:
Set x = RSWApp.om.FindElement("testProd","SELECT","ID")
Usually you will use whatever is available. Since the select element has no name or ID on the Empirix home page, I used the onChange attribute. You can use any attribute as long as you specify which one you are using (last argument in these examples)
You can use the FindElement to grab links, text boxes, etc.
The next example grabs from a link on a page
Home
Set x = RSWApp.om.FindElement("Home","A","innerText")
I hope this helps clear it up.

How to get the SQL Signon that Agent Jobs "Run As" or "Executed as User"

How to get the SQL Signon that Agent Jobs "Run As" or "Executed as User"?
I have an install SQL scripts that creates a Linked Server. I want to put some security on the Linked Server and only grant the Agent Job Signon (the "Run As" or "Executed as User") access to the linked server. I need to retrieve the
Agent Job Signon (something like "NT SERVICE\SQLAgent$FIDEV360BI02").
I could query certain jobs and SUBSTRING the Message column - using some form of the query below, which would return "Executed as user: NT SERVICE\SQLAgent$SSDEVBI02. The step succeeded." But that is pretty imprecise.
use msdb
SELECT [JobName] = JOB.name,
[Step] = HIST.step_id,
[StepName] = HIST.step_name,
[Message] = HIST.message,
[Status] = CASE WHEN HIST.run_status = 0 THEN 'Failed'
WHEN HIST.run_status = 1 THEN 'Succeeded'
WHEN HIST.run_status = 2 THEN 'Retry'
WHEN HIST.run_status = 3 THEN 'Canceled'
END,
[RunDate] = HIST.run_date,
[RunTime] = HIST.run_time,
[Duration] = HIST.run_duration,
[Retries] = HIST.retries_attempted
FROM sysjobs JOB
INNER JOIN sysjobhistory HIST ON HIST.job_id = JOB.job_id
-- CHANGE THIS
-- WHERE JOB.name like '%GroupMaster%' or Job.name like '%etlv%'
ORDER BY HIST.run_date, HIST.run_time

by default all sql jobs are executed as sql server agent account, unless otherwise a proxy is setup.
you can get the proxy information as Olaf mentioned, if the proxy_id is null for the step, it implies that the job step was executed as sql server service account and in such case it will be null
so, if it is null, it ran as sql server agent account.
so, one work around is get the sql server agent service account and if the proxy is null, that means it ran as sql server agent account, so, use isnull function. the disadvantage would be if the sql server agent account was switched, you might not get the
accurate information as the new account will show up though the job really ran as old account, to get this information, you need to get this from the logmessage column as you mentioned above.
try this code...
/*from sql 2008r2 sp1, you get the service accounts using tsql,otherwise you have to query the registry keys*/
declare @sqlserveragentaccount varchar(2000)
select @sqlserveragentaccount= service_account
from sys.dm_server_services
where servicename like '%sql%server%agent%'
select message,isnull(name,@sqlserveragentaccount) as AccountName
from sysjobhistory a inner join sysjobsteps b
on a.step_id=b.step_id and a.job_id=b.job_id
left outer join sysproxies c on c.proxy_id=b.proxy_id
Hope it Helps!!

How to execute a .sql file from a batch file

Hi all
I've to take backup of a database weekly twice on every wednesday & Friday @ 5pm IST. I've written a hot backup script, which works every well.
now i want to automate the script. ie i want this script to run on wednesday & friday @ 5pm without any human interfearance ie with out actually any1 executing this script.
i created a batch file prod.bak with the following lines
@echo off
set oracle_sid=testdb
set oracle_home=d:\oracle\ora92
sqlplus /nolog
connect sys as sysdba/oracletest@testdb
this batch file when eexecuted connects me to sql prompt.
Now i want to execute my backup script bkp.sql automatically when it is connected to sql prompt.
(i tried with these lines in the above batch file...
call bkp.sql---it just opens the bkp.sql file in notepad & displays the script
start bkp.sql---same as call
connect / as sysdba/pwd@[email protected] --- does not work simply remains a the sql prompt.
At 17:00 /Every:w,f "d:\bkp.sql"---does not work simply remains at the sql promt.)
Can any1 let me know what should i write in the batch file that will execute the bkp.sql file automatically after it gets connected to sql prompt. M using oracle 9i.
I'll manage he time through windows utility of scheduling task.. Let me know how to execute the .sql file from a batch file.
Thanks
Tripti

Try
sqlplus "sys/oracletest as sysdba" @bpk.sql
Working locally, and having set the ORACLE_SID, you don't need to specify the SqlNet alias (@testdb).
Remember to put an exit at the end of the bpk.sql script.

How do I Display a string from a servlet into a JSP Page???? NEED HELP!!!!

Hi guys,
How do I Display a string from a servlet into a JSP Page...
Ive tried so many bloody things!.....
Simply.
I get text from JSP. The servlet does what ever it does to the string.
Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
please help!!!

hmmm, I dont really like using JSP programming, u should be using JAVA..
the way to do it is:
Call and cast to the bean like this:
<%@ page import="beans.*" %>
<% //cast to bean get request create object
userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
then... all you do is call it like this:
<input type="text" name="firstName" value="<%= u != null? u.getFirstName(): "" %>">
this is the real programmers way,,,

How to get the Database type from weblogic Db connection

I want to use database version control in my application . that means different database type use different Sql Statement. Such as in weblogic7.0 if I create SqlServer JDBC pool then I will use some special Sqlserver sql Statement . such as some join statement. If I create Oralce JDBC pool then I have to use different Sql statement . because these two database support different Sql statement.
What my question is how to get the database type from the connection.

For a normal jdbc driver you can use
Connection.getMetaData()
To get the meta data, in particular the getDatabase...() methods.
That might or might not work.
However, at the very least in the server you have access to the weblogic properties so you can parse the pool property to figure it out.

Copy/paste sql strings from development ide's.

Our team have just started using this tool in favor of the well-known toad. Frist impressions are really good, so keep up the good work! But sometimes you find that a very simple feature has great impact on coding effectiveness.
Very often people copies sql strings from their java development ide's and want to test this in their database tool. For instance:
" SELECT ... " +
" FROM ...." +
" JOIN ...." +
" WHERE ....";
Should become
SELECT ...
FROM ...
JOIN ...
WHERE ....
The same goes backwards, if you write a sql statement in your database tool you would like to quickly convert it to a java string. This perhaps simple, but beloved by us, little feature was available in our previous tool, but I can't find it in sql developer. I've temporarily solved this by using the search-and-replace dialog box with regular expressions. This is however quite awkward to do each time so my options are:
* Assign this search-and-replace operation to a hot key (is this possible?)
* Write an extension (I have trouble finding good documentation of extension development for sql developer)
* Request a feature (will probably take time even if it's accepted)
Could anyone give me some hints on how to solve this?
Or have I missed anything, is it already available somewhere in the tool?
Thanks.

Hi,
sometimes you find that a very simple feature has great impact on coding effectiveness.Tell me about it ;-)
* Assign this search-and-replace operation to a hot key (is this possible?)
By default, ctrl-r does a search-and-replace. There's a history drop-down to have a quick access to your regular expression once you've entered it once.
* Write an extension (I have trouble finding good documentation of extension development for sql developer)
You have some samples on Kris' blog.
* Request a feature (will probably take time even if it's accepted)
I agree, think it's difficult to make it some universal feature everyone wants to use.
Another thing that comes to mind is recording a macro (see the tip on the Exchange for help on this).
And I supose you could even make an external tool for this, using a batch file or something. This is much easier than an writing an extension i guess, and you can write it in the language you like best...
Hope this helps,
K.

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

How to call a SQL function from an XSL expression

Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :
