Microsoft ODBC Error

Question

Hello,
I'm testing the following code that contects to an Access Database
import java.sql.*;
public class AccessTest
public static void main(String[] args)
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String dataSourceName = "scan";
String dbURL = "jdbc:odbc:" + dataSourceName;
Connection con = DriverManager.getConnection(dbURL, "","");
Statement s = con.createStatement
ResultSet.TYPE_SCROLL_SENSITIVE,
          ResultSet.CONCUR_UPDATABLE);
s.execute("select * from test");
ResultSet rs = s.getResultSet();
if (rs != null) // if rs == null, then there is no ResultSet to view
while ( rs.next() ) // this will step through our data row-by-row
/* the next line will get the first column in our current row's ResultSet
as a String ( getString( columnNumber) ) and output it to the screen */
// System.out.println(rs.getString("f_name")+"\t\t");
rs.updateString("l_name","Welcomer ");
                    rs.updateRow();
// System.out.println("Last Name: "+rs.getString(2));
System.out.println("Number: "+rs.getString(3));
     System.out.println("Age: "+rs.getString(4));
     //System.out.println("Date: "+rs.getDate(5));
     //Date tmp = rs.getDate(5);
     System.out.println();
s.close(); // close the Statement to let the database know we're done with it
con.close(); // close the Connection to let the database know we're done with it
catch (Exception err) {
System.out.println("ERROR: " + err);
the code that is commented out, was done so as I tried to debug this. What I'm trying to do is update the field l_name in a record. Yes I know using SQL update will do it, but I need to it this way for my application that I'm designing. The error I get is
java.sql.SQLException :[Microsoft][ODBC Microsoft Access Driver] Error in row.
the table in question only has 3 entries. The last name is updated for the first only, thus the error is coming up before the result set is moved by one. Please advise.
Thanks in advance

Answer 1

Access does support updatable queries, but sometimes it seems to choke on the string version of the column designator parameter.
Instead of:
rs.updateString("l_name","Welcomer ");
...try the integer parameter version instead.
Another thing to try is providing the column names instead of just a select * from. Many complex SQL statements will fail when you use 'select * from' because it looks into the column list to find the column names to use. '*', while understood by the database, will probably not provide much of a list of column names for the driver to use in your call to rs.updateString("l_name","Welcomer ");
Just some ideas, I am not sure if they are your answer though.
