I am trying to insert a row into a table (userGames), using Ucanaccess, and, when executing the statement, am recieving the following error:

In my connect class, i have the following:
private Connection conn;
public Connect(String filepath) {
try {
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
conn = DriverManager.getConnection("jdbc:ucanaccess://" + filepath + ";");
System.out.println("Connection successful");
} catch (Exception e) {
System.out.println("ERROR: " + e);
e.printStackTrace();
}
}
and the update/insert method:
public boolean update(String sql) {
boolean result = false;
try {
Statement stmt = conn.createStatement();
result = stmt.execute(sql);
} catch (SQLException ex) {
Logger.getLogger(Connect.class.getName()).log(Level.SEVERE, null, ex);
}
return result;
}
I am sending the following SQL statement to the update method:
"INSERT INTO userGames (userID,gameID) VALUES ("+users[id]+","+games[i]+")"
I have no idea what an "unknown token" is, or what I should do to rectify the error.
I have read the guide for Ucanaccess, and they do the same thing as I am doing, as far as I can see. Both .execute and .executeUpdate throw this error, and I do not know what to do.
Thanks for any help
Riccorbypro
The error is happening because you have pasted strings into your SQL, without enclosing them in ' ' marks, so the SQL has some words in it that the database doesn't know how to interpret.
You should be using a PreparedStatement, and setting users[id] and games[i] to parameters within the PreparedStatement. This is explained fully in The Java Tutorials
What David Wallace said .....
"INSERT INTO userGames (userID,gameID) VALUES ('"+users[id]+'",'"+games[i]+"')"
The easiest way to debug this is to just print your SQL statement before you execute it.
But you really should use a PreparedStatement

I've been searching the web for days and try to fix my problem by myself, but can't seem to get it fixed:

The error is relating to this sql
String selectSQL = "SELECT * from easyl";
PreparedStatement preparedStatement = c.prepareStatement(selectSQL);
preparedStatement.setInt(1,1001);
as you can see there is no query parameters or where clause
if you want all rows then simply remove
preparedStatement.setInt(1,1001);
I am trying to insert a new row in my HSQLDB database. I have this code:
private final String SQL_CREAR_ATLETA=" INSERT INTO ATLETA (ID_ATLETA, DNI, NOMBRE, APELLIDOS, GENERO, NACIMIENTO, CORREO, TELEFONO, CODIGOFEDERACION) VALUES (?,?,?,?,?,?,?,?,?) ";
#Override
public void crearAtleta(String dni, String nombre, String apellidos, char genero, Date nacimiento, String correo,
String telefono, String codigoFederacion) throws SQLException {
try {
con = Jdbc.getConnection();
pst = con.prepareStatement(SQL_CREAR_ATLETA);
Integer idAtleta = calcularIdAtleta(); /*this is not null , it gives the next id , for example if there are 3 athlete in the DB , will return a 4*/
pst.setString(1, String.valueOf(idAtleta)); // <- the code crash here
pst.setString(2, nombre);
pst.setString(3, apellidos);
pst.setString(4, String.valueOf(genero));
pst.setDate(5, new java.sql.Date(nacimiento.getTime()));
pst.setString(6, dni);
pst.setString(7, correo);
pst.setString(8, telefono);
pst.setString(9, codigoFederacion);
pst.execute();
} catch (SQLException e) {
e.printStackTrace();
}
}
The program crashes at the line pst.setString(1) to set the id into the sql sentence. The stackTrace is this one :

I don't unserstand the problem. I tried to change the data type, but nothing seems to work. My table is this one:
Even though you haven't disclosed all relevant code, the problem is likely that you are re-using the same PreparedStatement object across different methods. You are probably querying the next player id in calcularIdAtleta() using pst, which will leave the statement closed when calcularIdAtleta() returns. You shouldn't do that. Instead, use method-local variables; they make your code easier to read and less error-prone.
Try changing your method into this instead, essentially declaring the PreparedStatement locally:
public void crearAtleta(String dni, String nombre,
String apellidos, char genero,
Date nacimiento, String correo,
String telefono, String codigoFederacion) throws SQLException {
PreparedStatement ps = null;
try {
ps = Jdbc.getConnection().prepareStatement(SQL_CREAR_ATLETA);
Integer idAtleta = calcularIdAtleta();
ps.setString(1, String.valueOf(idAtleta));
ps.setString(2, nombre);
ps.setString(3, apellidos);
ps.setString(4, String.valueOf(genero));
ps.setDate(5, new java.sql.Date(nacimiento.getTime()));
ps.setString(6, dni);
ps.setString(7, correo);
ps.setString(8, telefono);
ps.setString(9, codigoFederacion);
ps.execute();
} catch (SQLException e) {
e.printStackTrace();
} finally {
if (ps != null) {
ps.close();
}
}
}
I have a problem with my java code. When I do a database update but they don't work up . I used the three methods that I found on the internet and still they have not worked!
Help me

From the log that you posted as answer, column ISMI is a mandatory field for your database table, it seems like a primary key.
You need something like:
uprs.updateInt("ISMI", someValue);
to complete your new row data.
Please also note that primary key must be unique in table.
I used the java prepared statement in a try-with-resources statement to access a table
in the Java DB database with NetBeans 8.0 IDE. After running the executeUpdate method ,
I then runned the generated keys method to retrieve all auto generated values.
However the generated keys resultset gives a null point error. The table has
an auto generated primary key.
the code snippet is presented below.
try (Connection con = DriverManager.getConnection(host, uName, uPass)) {
con.setAutoCommit(false); //disable auto commit
try( PreparedStatement stmAlumnus = con.prepareStatement(insertSQL)) {
stmAlumnus.setInt(1, Integer.parseInt(id_TextField.getText().trim()));

Is there an explanation for the error produced.
When you prepare the statement, you have to use a flag.
e.g.
ps = connection.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
I have written a test program that makes a Derby connection and creates the necessary tables if they do not exist. But once I run the programme I can't rerun it again because the exception I have brought. I think that I should add a finilize method to the current singletone class and close the connection there. Is it the solution?
But anyway I consider the possiblity of the program crash and exiting from the program in an abnormal manner. In that case how can I force to close the other instances of the connection to the database safely and make my own connection?
public class DBTest {
public static void main(String[] args) {
DBConnection.getInstance();
}
}
public class DBConnection {
private static DBConnection ourInstance = new DBConnection();
private Connection connection;
public static DBConnection getInstance() {
return ourInstance;
}
private DBConnection() {
String driver = "org.apache.derby.jdbc.EmbeddedDriver";
String dbName="C:/Users/Puk/IdeaProjects/DerbyTest/database/Ablauf";
String connectionURL = "jdbc:derby:" + dbName + ";create=true";
try {
Class.forName(driver);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
try {
connection = DriverManager.getConnection(connectionURL);
} catch (SQLException e) {
e.printStackTrace();
}
createTables();
}
private void createTables(){
Statement s;
try {
s = connection.createStatement();
s.execute("CREATE TABLE category ( id SMALLINT NOT NULL GENERATED ALWAYS AS IDENTITY \n" +
"\t(START WITH 0, INCREMENT BY 1), title VARCHAR(100))");
} catch (SQLException e) {
e.printStackTrace();
}
}
}
