This is my source code.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.ResultSet;
public class DBConnect {
public static void main(String[] args) {
try {
String host = "jdbc:derby://localhost:1527/Employee";
String uName = "jayani";
String uPass = "jayani";
Connection con = DriverManager.getConnection(host, uName, uPass);
Statement stmt = con.createStatement();
String sql = "SELECT*FROM WORKERS";
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {
int id_col = rs.getInt("ID");
String fname = rs.getString("FIRST_NAME");
String lname = rs.getString("LAST_NAME");
String job = rs.getString("JOB_TITLE");
System.out.println(id_col + "" + fname + "" + lname + "" + job);
}
} catch (SQLException ex) {
System.out.println(ex.getMessage());
}
}
}
Here i got an exception like "executeQuery method can not be used for update." What is this exception and how can I solve this. Thank you.
You need to use executeQuery like this
Statement stmt = null;
String query = "select * from <tablename>";
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);
