Problrm in prepared statement
I am trying to updating a table using prepared statement using executeupdate(). I need to write to a reject file if my update fails , the rejected resultset. I have tried to use getresultset() on preparedstatement and it does not work. any sugessions please.
fred
Hi,
An executeUpdate returns to you an integer and not a resultset.Hence you won't be getting any resultset.You can try checking for a nonzero number returned by executeUpdate() to signify a sucess.
Hope this will help you.

Use of Prepared Statement in adf
Hi Experts,
I am confused with the Use of prepared statement in adf.
My use case is ,
I have to update a table from every page in my application under certain conditions.
My question is ,
whether I have to create the VO iterator binding in every page and by calling the createinsert and insert the data in to the table or
use a common method in the Application module impl
which is using a prepared statement,(which is not even creating the ViewObject ) like
PreparedStatement st = null;
String sql = "INSERT INTO hr.departments (DEPARTMENT_ID, DEPARTMENT_NAME, MANAGER_ID, LOCATION_ID) VALUES (seq,?,?,?)";
st=getDBTransaction().createPreparedStatement(sql,0);
st.setString(1, name);
st.setString(2, mgr_id);
st.setString(3, Loc_id);
st.execute();
getDBTransaction().commit();which is the best approach?
Studio Edition Version 11.1.1.2.0
RanjithRanjith,
Without further understanding the use case, there's not really much difference between the two approaches. In both cases, you'd have a binding in the page definition (either an iterator binding for the VO or a method binding for the AM service method). Both will use bind variables. The main difference I can see is that, depending on how you have configured your AM pooling settings, the VO method will incur fewer parses in the DB because the AM will cache prepared statements for you.

Proving prepared statements are being reused
How can I prove that a prepared statement from a JDBC driver is being reused / pooled ?
What essentially I want to do is to have prepared statements reused to reduce hard parsing ... but I also need to prove that the statements are being reused. If I query the statement in V$SQLAREA, the column PARSE_CALLS does not seem to be distinguish between hard parse and soft parse:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96536/ch3204.htm#1126299
I am only interested for now in proving the just ONE statement is being reused ... which mean that the number of hard parses is very low compared to the number of soft parses for that ONE statement.

jmsHi,
No, parse calls is all soft and hard parse together. What you would see, if used absolutely correctly, would be 1 hard parse per session and many executions.
But since v$sql is obviously not linked to v$session other than at the time of exection, you see the aggregated parse calls and executions for each cursor. So what you should see is parse calls go up relatively slowly to the number of exections.
However, you can see soft and hard parses using the v$sesstat and v$statname views so you can see soft and hard parses on a session by session basis, be these are again aggregated, so you can't see soft / hard counts per cursor, only the total for a session.
What I see a lot of the time is they don't get it quite right, so hard parses is low but soft parses are high, so they are still parsing when they don't need to, but at least they are binding and using shareable SQL, which is a step in the right direction.
When I say 'they', it is a generic reference to all Java/.Nyet programmers writing front end code where they just don't 'get' parsing and binding because it's just too complicated and hey, SQL Server isn't like this...!

When to use prepared statement in java?
Hi all,
If we have query like select * from {tablename} (Here tablename is the variable) then will the use of prepared staement improve the performance? My guess is use of statement in this case is a better option rather than prepared statement as the tablename may change for every other query.I think are not useful if tablename changes.They are useful only when the where clause has dynamic values.cantor wrote:
Are you sure that your approach is possible? The next example causes exception for me.
PreparedStatement ps = conn.prepareStatement("select * from ?");
ps.setString(1, "TABLE_NAME");
ps.executeQuery();
I didn't say that he should solve it in that way. He should create one prepared statement like this "select a, b, c from tablename1" and another prepared statement when he wants to execute "select d, e, f from tablename2"
>
And as I understand, this code will not improve perfomance (and even will not work). As I said it can.
Prepared statements make possible usage compiled queries inside DB. When DB gets prepared statement call, it need to parse it only once. And it can collect some statistic to improve execution plan. But when table name is not specified, this approach will not work.Yes it might. There are database drivers that can cache prepared statements and it's isn't likely that he executes that query on more than e.g. 20 tables?
The database can also cache compiled statements in a cache.

How do I handle NULL returns from prepared statement?
Thanks in advance to all those who respond. As a beginner with Java/JSP/JDBC, I need all the help I can get!
Here's the problem...
I'm using a prepared statement in JSP to query a MySQL database.
If there is a value to return, everything works properly.
If the query returns a NULL (empty set) value, I get the following error:
javax.servlet.ServletException: Before start of result set
Here's the code (no negative comments please...I know I'm violating some conventions! I'll restructure it later. Right now I just need help with handling the NULL case):
<%
Driver DriverAppt = (Driver)Class.forName(MM_test_DRIVER).newInstance();
Connection ConnAppt = DriverManager.getConnection(MM_test_STRING,MM_test_USERNAME,MM_test_PASSWORD);PreparedStatement StatementAppt = ConnAppt.prepareStatement("SELECT lastname FROM appts_pid1 WHERE user_id = " + Recordset1__MMColParam + " AND year = " + yy + " AND month = '" + months[mm] + "' AND date = " + dates[dd] + " AND appttime = '16:15:00'");
ResultSet Appt = StatementAppt.executeQuery();
boolean Appt_isEmpty = !Appt.first();
boolean Appt_hasData = !Appt_isEmpty;
Object Appt_data;
int Appt_numRows = 0;
%>
Thanks for the help!!!I think I have a better handle on what's occurring here. To cut to the heart of the problem, I'm going to give a very simple example that illustrates what type of error handling I need.
HERE'S THE EXAMPLE:
Let's say that I have a database of users. There are only two columns in the database: user_id and lastname. There are only 2 users, user_id "1" has lastname "Jones" and user_id "2" has lastname "Smith".
I built a very simple web interface that let's a user enter a number to see if there's a lastname associated with that record. The user has no way of knowing if the user_id exists or not, so they may or may not enter a valid number.
If the user enters a valid user_id (in this case "1" or "2"), then the correct lastname is displayed. If the user enters an invalid user_id (in this case, anything other than "1" or "2") then I get the same "Before start of result set" error that I'm getting in my real application.
So, the question is: WHERE IN THIS CODE WOULD I HANDLE THE RETURN OF AN EMPTY SET?
The goal here is to have the sentence say "The user's lastname is .", basically returning null. If there has to be a value, then have the last sentence say "The user's lastname is unknown."
If you can solve this simple example, you'll have also solved the problem with my main application!!!! :-)
Here's the example code:
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<%@ include file="Connections/example.jsp" %>
<%
String Recordset1__MMColParam = "1";
if (request.getParameter("user_id") !=null) {Recordset1__MMColParam = (String)request.getParameter("user_id");}
%>
<%
Driver DriverRecordset1 = (Driver)Class.forName(MM_example_DRIVER).newInstance();
Connection ConnRecordset1 = DriverManager.getConnection(MM_example_STRING,MM_example_USERNAME,MM_example_PASSWORD);
PreparedStatement StatementRecordset1 = ConnRecordset1.prepareStatement("SELECT * FROM test_table WHERE user_id = " + Recordset1__MMColParam + "");
ResultSet Recordset1 = StatementRecordset1.executeQuery();
boolean Recordset1_isEmpty = !Recordset1.next();
boolean Recordset1_hasData = !Recordset1_isEmpty;
Object Recordset1_data;
int Recordset1_numRows = 0;
%>

Connection/ResultSets/Prepared Statement opening and closing
Hi all another question that was sparked by a thread that I recently read. I believe it was duffmo who got the code from jverd. The code I am referring to is to have an open and close connection specified in a Utility or Database class. I wanted to know if there was any issues with having methods that open and close connections/result sets/ preparedStatements. Currently I am putting the finally blocks inside each of my methods. There is obvious benefits to putting the methods in a class on their own (namely code re-use) but I wanted to know if there are any dangers. (This may seem like a dumb question, but I've found from experience it's the things that you don't know that will cost you loads of time).
thanks again.Hi all another question that was sparked by athread
that I recently read. I believe it was duffmo who
got the code from jverd. Generally speaking it's fine.
But as always you may have some long term design
issues to think about. If you build a simple
framework that consists of one class and that does
all that your program does then great.
Once you start add more complexity though you'll want
to be careful that you aren't reinventing the Spring
wheel or even ending up implementing your own
connection pool. Both of which, judging from posts
here seem to happen from time to time.
So I guess all in all, yes it's much better than
scattering the code all about but depending on what
you are going to be doing with it you may want to
look at the various ORM frameworks to see if they are
really the direction you should be going in.Thanks for the information cotton. I just wanted to make certain that it was a sensible thing to do. When I had first asked about connections I was told they should be opened an closed in the same spot, unfortunately I took that explanation a little too much to heart, and started opening and closing every connection resultset and prepared statement in each of the DAO classes that I was using.
Guess it's going to be a bit of work to refactor, but worth it for the cleaner code that will result. -
Pass table name as parameter in prepared Statement
Can I pass table name as parameter in prepared Statement
for example
select * from ? where name =?
when i use setString method for passing parameters this method append single colon before and after of this parameter but table name should be send with out colon as SQL Spec.
I have another way to make sql query in programing but i have a case where i have limitation of that thing so please tell me is it possible with prepared Statment SetXXx methods or not ?
Thanks

Could not find prepared statement with handle %.
Greetings. I've seen several posts for this error on the web, but no clear cut answers. I captured the code below in profiler, with the intention of replaying in mgmt studio.
However, the attempt end in the following error: "Could not find prepared statement with handle 612."
declare @p1 int
set @p1=612
declare @p2 int
set @p2=0
declare @p7 int
set @p7=0
exec sp_cursorprepexec @p1 output,@p2 output,N'@P0 int,@P1 int,@P2 int,@P3 int,@P4 bit',N'EXEC dbo.mySproc @P0,@P1,@P2,@P3,@P4 ',4112,8193,@p7 output,219717,95,NULL,1,0
select @p1, @p2, @p7
Something noteworthy is that my sproc only has 5 input parameters, but this makes it look like it has many more.
How do I manipulate the code enough to make it work in mgmt studio? Thanks!
TIA, ChrisRDBAIn profiler you would normally see RPC:Starting and RPC:Completed. The statement shown in RPC staring is what you need to pick because as Erland explained, completed would show "funky" behavior.

}This code successfully deployed my application on desired managed server but my application is in 'Prepared' state instead of 'Active' state.
Currently, I have to manually update my application's state to 'Active'.
Can anybody tell me if I am missing something in my code.It actually looks fine, but what could be the problem is the time to deploy your application and
the sleep command of ten seconds. When your sleep is finished, is your application deployment finished?
Maybe you can add a while loop using the isCompleted method of the DeploymentStatus class, for example,
ProgressObject processStatus = deployManager.distribute(deployTargets, new File("\\\\10.0.0.47\\Builds\\VertexTest\\domain1\\tc3.3b74_6.2.2011.19\\test.ear"), null,options);
DeploymentStatus deploymentStatus = processStatus.getDeploymentStatus() ;
while (!deploymentStatus.isCompleted()) {
Thread.sleep(1000);
TargetModuleID[] targetModuleIDs = deployManager.getAvailableModules(ModuleType.EAR, deployTargets);
System.out.println(targetModuleIDs);
if (targetModuleIDs.length > 0) {
deployManager.start(targetModuleIDs);
}Or something else along those lines. -
Batch updates with callable/prepared statement?
The document http://edocs.bea.com/wls/docs70/oracle/advanced.html#1158797 states
that "Using Batch updates with the callableStatement or preparedStatement is
not supported". What does that actually mean? We have used both callable and prepared
statements with the batch update in our current project (with the Oracle 817 db).
It seems to run ok anyway.So the documentation should state that batch updates do not work ok in old versions
of JDriver for Oracle, BUT work correctly with newer version. Additionally, batch
updates work ok when used with Oracle supplied jdbc-drivers?

Prepared statements related problem
Hi,
i have this strange problem with prepared statements i think.
When i execute an insert query without prepared statements i works fine (always), when i use prepared statements it sometimes gives a db error saying i'm trying to insert a null value.
The problem is that I'm not!!!
If i were why does it work sometimes?
It may be a bug but i don't know where to look for it... is it a prepared statements, application server or db2 problem?This is the code...

Hello all!
I am trying to get this prepared statement to work but am getting an error that I cant understand.
Basically I have a class file that the ps resides in. I am calling the ps from a jsp.

java.sql.Timestamp ts=new java.sql.Timestamp(currentDate.getTime());//Create the timestamp from the above date object.
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
objConn = java.sql.DriverManager.getConnection("jdbc:odbc:sensorWeek","","");
PreparedStatement ps = objConn.prepareStatement(insertStatement);
ps.setString(1, userid);
ps.setString(2, ipaddress);
ps.setTimestamp(3, ts);
ps.setString(4, page);

Error with ExecuteQuery() in prepared statement
Hello,
i' m a new one at java. I' m trying to build a web application in jsp and i have a problem in a simple at log in authentication.
My code is this:
<html>
<head>
<title>Welcome to the online Boat Shop, Inc.</title></head>
<body>
<%@ page language ="java" import = "java.io.*, java.lang.*, java.sql.*" %>
<% try
String strUsername = request.getParameter("USERNAME");
String strPassword = request.getParameter("PASSWORD");
Class.forName ("org.apache.derby.jdbc.ClientDriver");
Connection myConn = DriverManager.getConnection("jdbc:derby://localhost:1527/boatsdb","tony", "logo");
String strSQL = "SELECT USERNAME, PASSWORD FROM BOATDB where USERNAME = ? and PASSWORD = ?";
PreparedStatement stmt = myConn.prepareStatement(strSQL);
stmt.setString(1, "USERNAME");
stmt.setString(2, "PASSWORD");
ResultSet myResult = stmt.executeQuery(strSQL);
if(myResult.next()){
out.println("Login Succesful! A record with the given user name and password exists");
} else {
out.println("Login Failed. No records exists with the given user name and password");
myResult.close();
stmt.close();
myConn.close();
} catch(Exception e){
out.println(e);
%>
</body>
</html>
The problem is that prepared statement doesn't support executeQuery() method and i can find any solution. The error is this:
java.sql.SQLException: Method 'executeQuery(String)' not allowed on prepared statement. I already have some data in my database so that it can return results.
Thank you.
Edited by: antonis on May 3, 2008 6:13 AMthank you, that was the problem. It seems that i have also done mistakes in passing the username and password from the forms to the database for checking, because the message that i get always when i log is that there is no user with this username kai password.
<form method=GET action=log1.jsp>
<font size=5> Username <input type=text name="USERNAME" size=20>
</font>
<br>
<font size=5> Password <input type=text name="PASSWORD" size=20>
</font>
<br>
<input type=submit name=action value="Submit">
</form>
That's the forms and combined with the code in the fist post should have worked. Any ideas?
thanks again. -
Using partition in prepared statement
Hello,
I am connecting to an oracle 9i database and write a prepared statement like
String query = "SELECT * FROM ADM.TABLE1 PARTITION (TABLE1_?)";
PreparedStatement pstmt = dbConnection.prepareStatement(query);
pstmt.setString(1, "20" + callDate); // Partitions are like TABLE1_20030605
ResultSet rs = pstmt.executeQuery();
I get this error ORA-00933: SQL command not properly ended
Any ideas if i am substituting the value correctly or if this is the right way to use prepared statement ?It is the wrong way to use a prepared statement.
You will need to create the string dynamically.
