        private readonly SchoolContext _context;

        public WhereValueExample(SchoolContext dataContext)
        {
            // Sets data context.
            _context = dataContext;
        }

        public void Example1()
        {

            //  Declares SqlQueryBuilder.
            var sqlbuilder = new SqlQueryBuilder();

            // Defines a SQL statement, and sets the WHERE condition: Title = "Physics".
            sqlbuilder.Select("*")
                .From("Course")
