Prepared statement problem in MS-ACCESS

good luck all
when i use the following code using ms-access and jdk1.4
i got exception that driver does not support the function
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:rtechdb");
//eror here // st=con.prepareStatement("insert into webnotes values(?,?,sysdate,?)");
str=con.prepareStatement("delete from webnotes where user_id=? and note_id=?");
stv=con.createStatement();
java.sql.SQLException: Driver does not support this function
at sun.jdbc.odbc.JdbcOdbcPreparedStatement.executeQuery(JdbcOdbcPrepared
Statement.java:118)
plz answer me
if i need to have another driver thatn plz send me the url to get it
thanks in advance

I think ACCESS does not have any function called "sysdate" in the following statement
st=con.prepareStatement("insert into webnotes values(?,?,sysdate,?)");
test with the following statement
st=con.prepareStatement("insert into webnotes values(?,?,date(),?)");
If the problem has nothing to do with "sysdate", post more info.
One thing I can assure you is that there is nothing wrong with the driver in this particular case.

Prepared statement not releasing from access db

Hello all,
I have several prepared statements like the following:
public void storeUpdate(String userId,String ws,String wm,String wl,String wx,String wxx,String bs,String bm,String bl,String bx,String bxx, String tq, String tp,Timestamp ts)
     String updatePurchase = "UPDATE store SET smallWhite=?,medWhite=?,lrgWhite=?,xlrgWhite=?,xxlrgWhite=?,smallBlue=?,medBlue=?,lrgBlue=?,xlrgBlue=?,xxlrgBlue=?,totalQty=?,totalPrice=?,ot=? WHERE playerNo='"+userId+"'";
     try{
         Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
         objConn = java.sql.DriverManager.getConnection("jdbc:odbc:myDB","","");
         PreparedStatement ps = objConn.prepareStatement(updatePurchase);
         ps.setString(1, ws);
         ps.setString(2, wm);
         ps.setString(3, wl);
         ps.setString(4, wx);
         ps.setString(5, wxx);
         ps.setString(6, bs);
         ps.setString(7, bm);
         ps.setString(8, bl);
         ps.setString(9, bx);
         ps.setString(10, bxx);
         ps.setString(11, tq);
         ps.setString(12, tp);
         ps.setTimestamp(13,ts);
         ps.executeUpdate();
         ps.close();
         objConn.close();
            catch (SQLException s)
                System.err.println("DataBase PROBLEM");
                s.printStackTrace();
            catch (Exception e)
                    System.err.println("Error in updateStore method");
                    e.printStackTrace();
} The prepared stmts seem to be "hanging on to" the access(dont laugh)table that the prepared stmt just updated. The reason I know this is because when I try to look at the table in access's design view I get a message saying:
"Microsoft access
You cant open the table 'store' for modification.
A query or form bound to the table is open, you may not have permission to open this table in design view, or another user has the table open.
If you have opened a query or form bound to this table, close it, and then try again to open the table in design view."
The only way to open the table in design view is to shut down tomcat and restart.
Should I be worried about this?
Am i forgetting to close something in my ps?
TIA!!

I use PreparedStatement all the time with Access and never have a problem. The only thing I noticed about your code is that if an exception gets thrown in your method, the close statements won't get executed. This might leave the tables locked. You might want to try moving the close statements into a finally block. That way your statement and connection will get closed if an exception gets thrown or not.

Prepared statement problem

I am trying, for some time now, to implement some sort of bank application that uses DBs to store customers.
I have been trying to improve my code, the results are interesting since while studing more I saw that the previous code was.....not so good. I am using Prepared statement now as some of you suggested but I cannot surpass this final glich.

Prepared statement problem using a field name that contains a "?"

I am attempting to execute the following query via use of a PreparedStatement:
select [Spread_By_Cost_Center?], Debit_Category, Credit_Category, Start_Date, End_Date, Allocation_Type From ALLOCATION_FORMULA Where FormulaID = ?
The query fails with the following message:
java.sql.SQLException: [Microsoft][ODBC Microsoft Access Driver]COUNT
field incorrect
However, I can run this query directly in MS-ACCESS, using a value for the substitution parameter (i.e., FormulaID = 1)
If I remove the "Spread_By_Cost_Center? field from the query within the PreparedStatement, the PreparedStatement query executes successfully.
So, it would appear that the "?" in the field name is possibly being treated as a substitution parameter. Is this a bug within PreparedStatement? I do not want to use a Statement object, as the PreparedStatement provides a much more elegant solution (when it works).
Any suggestions?

That may be so, but as I see it there are two alternatives:
1. Wait for the "bug" to be fixed.
2. Change the database to use less problematic column names.
I know which alternative I would choose.

Problem with Prepared Statement & MS Access

Hi
I have tried to find some info about this but can't see anything specific to what I think the problem may be. Hopefully someone can point me in the right direction.I am trying to get information out of an MS Access database using a Prepared Statement but I am getting strange results.
When I run the query in the database it gives me the correct totals (�51) for 4 records. When I run the Prepared Statement ,I get 81. Has it got anything to do with the data type I am using( sorry if this is a really basic question). here is my code- the connection etc is elsewhere.
private void getReportMoneyTotal() throws SQLException
          Calendar todayTotal =Calendar.getInstance() ;
           SimpleDateFormat reportDateFormat = new SimpleDateFormat("dd MM yyyy");
          PreparedStatement preparedT =context.getConnection().prepareStatement(
               "SELECT Sum(tblSession.Fee) AS Total, Count(tblBooking.BookingID) AS CountOfBookingID FROM tblSession INNER JOIN "+
               "(tblBooking INNER JOIN tblCustomer_Booking ON tblBooking.BookingID = tblCustomer_Booking.BookingID) ON tblSession.SessionID = tblBooking.SessionID "+
               "WHERE (((tblBooking.EventDate)>DateAdd('m',-1,#"+reportDateFormat.format(todayTotal.getTime())+"#)) AND ((tblSession.Session)='Morning' Or (tblSession.Session)='Evening')) OR (((tblSession.Session)='Afternoon') AND ((tblBooking.Extension)=Yes))"
          ResultSet resultTotal =preparedT.executeQuery();
          resultTotal.next();
          Double total =resultTotal.getDouble("Total");
          Locale locale = new Locale("GBP");
        NumberFormat gbpFormat = NumberFormat.getCurrencyInstance(locale);
          System.out.println(gbpFormat.format(total));
          preparedT.close();
     }I do realise that my code probably isn't very elegant but I'm only learning!

Hi Matt--
I am not clear if you are saving the url with the # # around
the text or if
the
data already contains the # marks.
When you insert a link, you want to make sure you insert is
insert into table ( link1) values ( <cfqueryparam
cfsqltype="cf_sql_varchar"
value='#linkvaluehere#'> )
remember to
1) enclose your data's value inside quotes (some databases
are picky about
single v. double quotes).
2) if it IS in quotes, swap doubles for singles and see if
that helps.
3) make sure your data being saved is NOT double hashed like
'##linkvalueher##'. Double ##'s tell
Coldfusion not to treat it as a variable.
hope his helps,
tami

Hi cruzdhel,
Your SQL looks incorrect to me.
I am not familiar with that syntax.
I think it should be like this:
PreparedStatement insertPersons =
conn.prepareStatement("INSERT INTO PERSONS (FIRST_NAME," +
                                           "LAST_NAME," +
                                           "MIDDLE_NAME," +
                                           "NICKNAME," +
                                           "GENDER," +
                                           "MARITALSTATUS," +

Prepared Statement, executing SELECT TOP in Ms Access

I'm having the following problem. I built an application fetching data without any problem from MS SQL Server, this was using prepared statements. Now i'm having this strange problem with the following query:
SELECT TOP 1 *
FROM table
WHERE appliance_id = ?
AND ttimestamp_initpk <= ?
AND ((Type = ?) OR (Type = ?) OR (Type = ?) OR (Type = ?) OR (Type = ?) OR (Type = ?))
ORDER BY ttimestamp_initpk DESC
While on SQL Server this fetches just a record, on MS Access it fetches the whole set of records without worrying about TOP instruction.
That is, it acts like a SELECT * FROM, and this slows down runtime behaviour.
I'm using sun.jdbc.odbc.JdbcOdbcDriver, is it the problem?
Thanks, Mirko

Thanks for your answer, but i'm not sure this is the reason.
I made one more test: i wrote a .Net application connecting to a MS Access using an ODBC connection. SELECT TOP statement is working fine, so i think i'll try another JDBC driver. Any other solution??
Thanks,
Mirko

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...
     public void insertArticolo(Articolo item) throws Exception {
          PreparedStatement ps = null;
               try {
                    StringBuffer sql = new StringBuffer("insert into RUW.RUWT1_ARTICOLO (");
                    sql.append("C_ENTE, C_CONCESSIONE,N_ANNO_RUOLO,N_PROGR_RUOLO,N_PARTITA,N_PROGR_PARTITA,N_PROGR_TRIBUTO, ");
                    sql.append("C_TRIBUTO, C_TIPO_UFF,C_UFFICIO,");
                    sql.append("C_TIPO_IMP, N_ANNO_IMP, L_CARICO, S_ARTICOLO");
                    sql.append(") values (");
                    sql.append("?" + ", ");

Passing values for a prepared statement encounters problem

I have a query which runs fine when executed from sqlplus
SELECT SYSDATE + (INTERVAL '10' MINUTE) FROM dual;
The same query when run using a java statement also works well.
when I use a Prepared statement like
String sql = SELECT SYSDATE + (INTERVAL ? MINUTE) FROM dual;
PreparedStatement ps = this.getPreparedStatement(sql.toString());
ps.setString(1, "10");
and execute I get the following exception
ORA-00920: invalid relational operator
I tried another way which also gives me a similar exception
String timeout = "10";
SELECT SYSDATE + (INTERVAL" + timeout + "MINUTE) FROM dual;
Can anybody tell me why the problem happens. Is anything wrong in passing values dynamically for an 'interval' function in oracle?

Yes friends
Thanks for the reply. It worked out this way as u said
sql.append("SELECT SYSDATE + (INTERVAL ");
sql.append("'" + Integer.parseInt(timeout) + "' MINUTE) FROM dual");
Mr.masijade said.
First of all, there is no reason to do this command, really, but okay.
There may be scenarios like this to use the command
select * from mytable where (systimestamp - lastUpdateTimestamp) > Interval '10' Minute
Is there any other better way to get all records updated before a certain timestamp?Use Timestamp to create a timestamp and PreparedStatement's setTimestamp(), maybe?

Problems with Prepared Statement

Hi,
I am developing an Java Bean that reads from a database of Entertainments of my home city of Glasgow and displays that info to a text area. I want the User to input the type of Entertainment they want e.g. Bars or Clubs, and the name of the place they want to go and then the Java Bean displays the info of the specified place.
The program works fine if I set the Query to display the data from the database but I want the User to define the query by thier input.
So I used Prepared Statements, but I have error messages saying that
Syntax Error in FROM Clause
my code to query the database is shown below
String query ="SELECT * FROM ? WHERE Name=?";
PreparedStatement PresStatement=con.prepareStatement(query);
//my input to test Database.will change to variable
PreStatement.setString(1,"Pubs");
PreStatement.setString(2,"Admiral");
ResultSet rs=PreStatement.executeQuery();The Problem seems to the placholder after the FROM clause but I can't seem to fix it.
Any Help would be greatly appreciated.
Regards
Brian

just a guess here, but I'd imagine it's because of the way PreparedStatement handles Strings. Obviously, if you're using a String as part of your SQL query, you're going to want single quotes around the entire thing. Thus, the first setString() is probably trying to put single quotes around the table name, which could be causing problems.
You don't really lose anything if you just work around this by changing your code to..
tableName = "Pubs"; //or this is probably coming from your user
String query ="SELECT * FROM "+tableName+" WHERE Name=?";
PreparedStatement PresStatement=con.prepareStatement(query);
//my input to test Database.will change to variable
PreStatement.setString(1,"Admiral");
ResultSet rs=PreStatement.executeQuery();

Problem with Oracle Prepared Statement

Hi all,
Please help me..
I Have 2 pages, in first page i had table with rows with update image for each row, when i click update it leads to 2nd page which shows the particular row information
my problem is, i am executing prepared statement with 2 parameters in 2nd page controller which is working fine first time, when i go to first page and comes to 2nd page again my
result set showing Null, some times query executing and getting results, some times null, i am confused with this behaviour. please help me ..
Thanks all

Hi ,
How your table is being popluated ? You have executed VO in PR or PFR ?
Please give snippet of your CO code , both after navigating from first page to second and again after coming back to first page .

Prepared Statement 8.1.7 problem with spaces

I have a char field that is char(10). It has characters like '39' stored in it. That is of course space filled.
When I try to use that field in a select statement where clause in a prepared statement it does not return any rows.
However, if I define the column as char(2) it works. If I define the column as varchar2(10) and put '39' in it (2 length) it works.
What is the problem anyone? I am using Java 1.3.1, and the Oracle JDBC thin client newest .jar file (12) for Oracle8.i
I have seen others have this problem but no solutions?

Update to problem
I have the latest (classes12.zip) JDBC drivers from Oracle.
We are running Oracle 8.1.6 and converting to Oracle 8.1.7.
This works the same with both.
Example, I have a column (char(10)) with trailing spaces. i.e. '39 '.
When I perform a Prepared Statement with that column in the where clause, it returns no result rows.
When I perform a standard statement with that column in the where clause, it returns rows.
When I define a column char(2) and use it in the where clause it works fine.
When I define a column varchar2(10) and load it with data like '39', it works fine.
When I define a column varchar2(10 and load it with data like '39 ', it does not work.
When I execute this same Prepared Statement through the jdbc:odbc bridge it works fine.
I cannot change the definition of the columns as they are foreign key data. What is the problem here? Any help is appreciated.
If you need further information please feel free to contact me.

Prepared Statement - updating problem

Hello all together!
I've a problem and I hope somebody could help me out of misery!
I have created a table and now I want to update a special cell and my aim is to use prepared statements
I have generated it in the form mentioned below:
public void setValueAt(Object newValue, int row, int col) {
try {
stmtPrep.setString(1, getColumnName(col)); // this should initalize the column I want to update
stmtPrep.setObject(2, newValue); //this is the new value which should be set
rowElements = getElementsOfRow(row);
stmtPrep.setInt(3, (Integer.parseInt((String)rowElements[0]))); //this is my primary key
stmtPrep.executeUpdate();
stmtPrep.clearParameters();
rs.updateRow();
} catch (SQLException e) {e.printStackTrace(); }
My SQL-Statement looks like this:
private String queryPrep = "update Buch set ? = ? where isbn = ?";
My problem is that column is not set.... am I not allowed to set column name in the prepared statement??
how do I manage to show my changes in a master/detail implementation?
anybode a clue????

Hi majandrah,
My SQL-Statement looks like this:
private String queryPrep = "update Buch set ? = ?
where isbn = ?";Sorry, not allowed.
My problem is that column is not set.... am I not
allowed to set column name in the prepared
statement??No, you are not. Parameters can only be used for literal values -- not for names of columns , tables, etc.
how do I manage to show my changes in a master/detail
implementation?
anybode a clue????I suggest using the java.text.MessageFormat class, like so:
MessageFormat queryPrep = new MessageFormat("update BUCH set {0} = ? where ISBN = ?");
String query = queryPrep.format(String[]{getColumnName(col)});
// Now use your (posted) code, starting at line...
stmtPrep.setObject(2, newValue);Good Luck,
Avi.

Problem in Wilcard Search (%) with Prepared Statement

Hello Everyone,
Im trying to search using the like operator within a prepared statement. The program compiles , but when I execute it I get an empty result set.
I tried the same query in Query Analyser in SQL Server 2000 and it worked flawlessly.
I searched on this forum also and I read recommendations suggesting
to put the ? in like '?'   This gives me an error.
Ive tried all options I could get my hands on ,now I request you all to please provide me some guidance.
Thankyou
The code snippet is as follows :
          String sDay= "%"+startDay+"%";
                ps= con.prepareStatement("Select * from Testdb where days like ? ");
          ps.setString(1,sDay);
          As I said earlier, this query returns and empty result set.
Thankyou once again.

Its next to impossible for me to switch to Statement from prepared S. because the Query has got way to many conditions and its next to impossible to handle all those in a statement.
I had originally started out with statement itself but then I switched to prepared statement as it was getting unmanageable.
I'll try finding a work around whereby I split the query into two parts using the manageable part and the Wilcard search in the statement and the other unmanageable part in the PS.
Else I will again have to attempt that. I had also had a feeling this was affecting it.
Thanks for the help.
If anyone has some solution please post it .
Thank you.
