/** * * @author jay */ import java.sql.*;  public class javaapplication1 { public static void main(string[] args) {    connection cn;   statement st;   resultset re;   string id ="username";    string name="password";       try{      class.forname("net.ucanaccess.jdbc.ucanaccessdriver");     cn=drivermanager.getconnection("jdbc:ucanaccess://d://j//db//database.accdb");     st = cn.createstatement();     string q ="insert db1 values('"+id+"','"+name+"'))";     st.executequery(q);      system.out.println("inserted")           catch(classnotfoundexception | sqlexception e)     {       system.out.println(e);     }  } }

i tried many different ways of inserting:

string q ="insert db1 (id,name) values('"+id+"','"+name+"'))";

when comment passed upper side , try direct values inserted 

string q ="insert db1 (id,name) values('a','b'))";

but got error

run: net.ucanaccess.jdbc.ucanaccesssqlexception: ucaexc:::3.0.3.1 unexpected token: ) build successful (total time: 0 seconds)

you trying use executequery perform insert, executequery select queries. try using executeupdate instead.

string q = "insert db1 ([id], [name]) values (?, ?)"; preparedstatement st = cn.preparestatement (q); st.setstring(1, "a"); st.setstring(2, "b"); st.executeupdate();
