主要是NHibernate連接MySQL注意事項:

在website的bin目錄里添加MySql.Data.dll（可在官方下載）和hibernate.cfg.xml

啟用新的OpenSession()方法

通過ADO連接數(shù)據(jù)庫的方式會出現(xiàn)“用戶名root無法登陸”的錯誤提示。所以全部通過NHibernate連接，使用NHibernate的函數(shù)。

在電腦上安裝MySql的時候注意選擇“Developer Machine”.要不然會出現(xiàn)無法啟動MySql服務(wù)的錯誤：

T-SQL和MySql一些常見的不兼容。

• top 10 -> limit index,length
• dbo. -> 空
• getDate() -> NOW()
• DATEADD(mi,15,GETDATE()) -> DATE_ADD(NOW(), INTERVAL 15 MINUTE)
• .....
