A full working example pulling data from the table from keywords.
import com.mysql.cj.protocol.a.result.ResultsetRowsStatic;
import java.sql.*;
public class sql_handler {
public sql_handler() {
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://192.168.2.200:3306/","root", "<password>");
Statement sql_query = con.createStatement();
ResultSet res_set = sql_query.executeQuery("SELECT * FROM fmp_data.fmp_table");
while(res_set.next())
{
String sym = res_set.getString("symbol");
String name = res_set.getString("name");
float price = res_set.getFloat("price");
String exch = res_set.getString("exchange");
String exch_sn = res_set.getString("exch_sn");
String stype = res_set.getString("stype");
}
} catch (Exception E) {
String Error = String.valueOf(E);
System.out.println(Error);
}
}
