I am unable to delete a row from my database. I included a photo with the table & the code. Down u can see the method i used(psmts). I also stated the id as an int . I tried several things and it id not worked so far. Is there any way i can make a delete a row by inserting an ID?

try{
Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
Connection con=DriverManager.getConnection("jdbc:ucanaccess://D:\\Temp\\film.accdb");
PreparedStatement psmt=con.prepareStatement("INSERT INTO filme (titlu_film,an_film,timp_film,film_limba) VALUES (?,?,?,?)");
//HERE I TRIED THE METHOD !!!!!!
PreparedStatement psmts=con.prepareStatement("DELETE FROM filme WHERE film_id=?");
String nume,data,timp,limba;
int id;
nume= t1.getText();
data= t2.getText();
timp=t3.getText();
limba= t4.getText();
id=Integer.parseInt(t5.getText());
if(e.getSource()==b1)
{
psmt.setString(1,nume);
psmt.setString(2,data);
psmt.setString(3,timp);
psmt.setString(4,limba);
psmt.executeUpdate();
}
if(e.getSource()==b2)
{
psmts.setInt(5,id);
psmts.executeUpdate();
}
con.close();
System.out.println("Success");
}catch(Exception r){
System.out.println(r);
}
}
public static void main(String[] arr)
{
new Fereastra1();
}
}
I believe the position reference is off for the delete?
Change:
psmts.setInt(5,id); // psmts delete parameter 5 ??
To:
psmts.setInt(1,id); // only 1 parameter in the delete prepared statement
