使用nHibernate调用存储过程(Calling a store procedure with nHibernate)

使用nHibernate调用存储过程(Calling a store procedure with nHibernate)

你如何用nHibernate调用存储过程？

具体来说，有两种情况我使用存储过程：返回标量值并返回映射到实体的一组结果。

How do you call a stored procedure with nHibernate?

Specifically there are two cases where I am using store procedures: to return a scalar value and to return a set of results mapped to entities.

该文档建议使用以下方法映射存储过程的命名查询：

<sql-query name="selectAllEmployments_SP"> <return alias="emp" class="Employment"> <return-property name="employee" column="EMPLOYEE"/> <return-property name="employer" column="EMPLOYER"/> exec selectAllEmployments //stored procedure call here </sql-query>

这可以通过使用：

IQuery q = sess.GetNamedQuery("selectAllEmployments_SP");

这将在NHibernate 1.2.0文档的13.2.2节（映射存储过程）和9.3.2（查询命名查询）中讨论。 https://www.hibernate.org/hib_docs/nhibernate/1.2/reference/en/html/querysql.html#sp_query

The documentation suggests the following for mapping a named query for a stored procedure:

<sql-query name="selectAllEmployments_SP"> <return alias="emp" class="Employment"> <return-property name="employee" column="EMPLOYEE"/> <return-property name="employer" column="EMPLOYER"/> exec selectAllEmployments //stored procedure call here </sql-query>

This could be called by using :

IQuery q = sess.GetNamedQuery("selectAllEmployments_SP");

This is discussed in section 13.2.2 (mapping stored procedure) and 9.3.2 (querying named query) of the NHibernate 1.2.0 documentation. https://www.hibernate.org/hib_docs/nhibernate/1.2/reference/en/html/querysql.html#sp_query
