{
    public class CloneExample
    {
        private readonly SchoolContext _context;

        public CloneExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example()
        {
            // Builds a SQL statement.
            var sqlBuilder = new SqlQueryBuilder();

            sqlBuilder.Select("name")
                    .From("Department");

            // Makes a copy.
            var sqlBuilderClone = (SqlQueryBuilder)sqlBuilder.Clone();

            // Adds the Where clause.
            sqlBuilderClone.WhereValue("DepartmentId", 1);

            string sql = sqlBuilder.ToSqlString(_context);
            Console.WriteLine("The SQL SELECT statement (sqlBuilder): \n{0}", 
                sql);

            sql = sqlBuilderClone.ToSqlString(_context);
            Console.WriteLine();
            Console.WriteLine("The SQL SELECT statement (sqlBuilderClone): \n{0}", 
                sql);
