java - "not Implemented by SQLite JDBC driver" -

-

i have database user information, , wanted make public static return database integers @ given time without having make void every single one, it's giving me error:

0 java.sql.sqlexception: not implemented sqlite jdbc driver     @ org.sqlite.jdbc3.jdbc3preparedstatement.unused(jdbc3preparedstatement.java:466)     @ org.sqlite.jdbc3.jdbc3preparedstatement.executequery(jdbc3preparedstatement.java:506)     @ dysanix.main.checkusercolumnint(main.java:726)     @ dysanix.main.main(main.java:50)

and code:

public static int checkusercolumnint(string column, string user) {         try {             connection connection = drivermanager.getconnection("jdbc:sqlite:database.db");             string query = "select ? usersettings user = ?";             preparedstatement statement = connection.preparestatement(query);              statement.setstring(1, column);             statement.setstring(2, user);              resultset result = statement.executequery(query);              result.next();             int columnresult = result.getint(column);             return columnresult;         } catch (exception e) {             e.printstacktrace();             return 0;         }     }

does understand i'm doing wrong? tried google things, changing code around moved me 1 error next... i'm not anymore @ point.

thanks in advance!

edit: running jdbc driver sqlite-jdbc-3.8.11.2.jar

preparedstatement.executequery(string sql) not implemented. guess want call executequery(). query defined preparedstatement already.
