园子里关于存储过程的讨论有很多，不少人建议将SQL语句写在程序中，这篇随笔讨论一下SQL语句在程序中的写法。

1string strSQL = "SELECT [AddressID], [AddressLine1], [AddressLine2], [City], [StateProvinceID], [PostalCode], [rowguid], [ModifiedDate] FROM [AdventureWorks].[Person].[Address] WHERE City = 'Bothell' ORDER BY AddressID";

　　这是最普通的一种写法，而且在开发中被广泛采用。

                string strSQL =     "SELECT " +
                                        "[AddressID], " +
                                        "[AddressLine1], " +
                                        "[AddressLine2], " +
                                        "[City], " +
                                        "[StateProvinceID], " +
                                        "[PostalCode], " +
                                        "[rowguid], " +
                                        "[ModifiedDate] " +
                                    "FROM " +
                                        "[AdventureWorks].[Person].[Address] " +
                                    "WHERE " +
                                        "City = 'Bothell' " +
                                    "ORDER BY " +
