How to split connection and query execution into two methods System.Data.SQLite;

Question

What is the best way to split connection and executing query into two methods?

using System.Data.SQLite;
internal SQLiteConnection ConnectToDb()
{
    using (SQLiteConnection dbConnection = new SQLiteConnection("@"DB\SWDB.db;"))
    {
        dbConnection.Open();
    }
    return dbConnection;
}

internal Qruery()
{
    using (SQLiteCommand cmd = new SQLiteCommand(query, dbConnection))
    {
        cmd.CommandText = query;
        cmd.CommandType = CommandType.Text;
        SQLiteDataReader reader = cmd.ExecuteReader();
        ......

    }
    dbConnection.Close();
}

Since both objects are disposable, dbConnection is destroyed after using is done, so query cannot be made.
