This is a project of Database Sessional (CSE-304) based on Raw SQL and NHibernate ORM. We choose the dataset of "Stack Exchange" to run our query.We ran some selected queries in both Raw sql and NHibernate ORM. Then we compare the execution time of both of these. And By this way...
NH-258 - Custom SQL support (including stored procedures) It may look fairly innocent comment, but it has quite an impact on several nay-sayers that will clutch stored procedures until you pry them out of their cold dead hands. Also, sometimes Stored Procedures (or raw SQL) are useful :-...
在OracleClient组件里,定义了“LONGRAW”和“RAW”类型对应的数据类型都是“byte[]”。 当NHibernate调用OracleCommand.Execute()时,OracleCommand.Execute()又会调用OracleParameter.CoerceValue(),OracleParameter.CoerceValue会调用System.Convert.ChangeType(aGuidObject, typeof(Byte[]), null),而Guid又没有实现IConv...

SQL—用户自定义函数 用户自定义函数是SQLServer的数据库对象,它不能用于执行一系列改变数据库状态的操作,但它可以像系统函数一样在查询或存储过程等的程序段中使用,也可以像存储过程一样通过EXECUTE命令来执行。用户自定义函数中存储了一个Transact-SQL例程,可以返回一定的值。 在SQLServer中根据函数返回值形式的不...
