I am using Umbraco 8.18.12 and trying to get some data from table but in case table is not there in DB getting error

 using (var scope = serviceProvider.CreateScope(autoComplete: true))
                {
                    var sql = scope.SqlContext.Sql().Select("*").Where<Item>(x => x.id == itemId);
                    var record = scope.Database.SingleOrDefault<Item>(sql);
                    if (record != null)
                    {
                        test = true;
                    }
                }

Doesn anyone know how I can check if table exist here ?
