MS Access Database problem - No data found [Resolved]
Hi guys,
Bit of a puzzler here. I've written an app that connects to a MSAccess DB fine. The DB has 3 colums - Employeename (Text or String), PassId (Number/long) and Passdate (Date/Time). All 3 columns have data entered in them. I can retrieve info from the first column but whenever I try to get data from the other two, tthe SQL Exception thrown tells me No Data Found.
Would really appreciate any help you could give me. Thanks in advance.
Code:
import java.sql.*;
import java.util.Date;
import java.util.Calendar;
public class Interactor {
private String URL = "";
private String username = "";
private String password = "";
private int employees = 0;
private Statement stmt = null;
private Connection con = null;
private String dataSourceName = "NewTest";
public Interactor ( String u, String p ) {
dataSourceName = "NewTest";
URL = "jdbc:odbc:" + dataSourceName;
username = u;
password = p;
setupConnection ();
}
private void P ( String S ) { System.out.print ( S ); }
private void PL ( String S ) { System.out.println ( S ); }
public void setupConnection () {
try { Class.forName ( "sun.jdbc.odbc.JdbcOdbcDriver" ); }
catch ( Exception e ) {
System.out.println ( "Failed to load JDBC/ODBC driver." );
return;
}
try {
con = DriverManager.getConnection ( URL, "", "" );
stmt = con.createStatement ();
}
catch ( Exception e ) {
System.err.println ( "problems connecting to " + URL );
System.err.println ( e.getMessage () );
e.printStackTrace ();
}
}
public void getPassDates () {
try {
ResultSet result = stmt.executeQuery ( "SELECT * FROM Emp;" );
result.next();
PL ( result.getString ( "Employeename" ) );
PL ( "" + result.getLong ( "PassId" ) );
PL ( result.getDate ( "Passdate" ).toString () );
while ( result.next () ) {
count ++;
PL ( result.getDate ( "Passdate" ).toString () );
PL ( "" + result.getLong ( "PassId" ) );
}
}
catch ( Exception e ) {
System.err.println ( e.getMessage () );
e.printStackTrace ();
}
}
public int getNoEmployees () {
try {
String q = "SELECT Employeename FROM Emp;";
ResultSet result = stmt.executeQuery ( q );
result.next(); // move to first row
PL ( result.getString ( "Employeename" ) );
//PL ( result.getDate ( 1 ).toString () );
employees = 1;
while ( result.next () ) {
employees ++;
PL ( result.getString( "Employeename" ) );
//PL ( result.getDate ( "Passdate" ).toString () );
}
PL ( "Number of employees : " + employees );
}
catch ( Exception e ) {
System.err.println ( e.getMessage () );
e.printStackTrace ();
}
return employees;
}
}
