    <p>I'm trying to make simple many-to-one association, using NHibernate.. I have class Recruit with this mapping:</p> <pre><code>&lt;class name="Recruit" table="Recruits"&gt; &lt;id name="ID"&gt; &lt;generator class="native"/&gt; &lt;/id&gt; &lt;property name="Lastname" column="lastname"/&gt; &lt;property name="Name" column="name"/&gt; &lt;property name="MedicalReport" column="medicalReport"/&gt; &lt;property name="DateOfBirth" column ="dateOfBirth" type="Date"/&gt; &lt;many-to-one name="AssignedOnRecruitmentOffice" column="assignedOnRecruitmentOffice" class="RecruitmentOffice"/&gt; </code></pre> <p></p> <p>which is many-to-one connected to RecruitmentOffices:</p> <pre><code>&lt;class name="RecruitmentOffice" table="RecruitmentOffices"&gt; &lt;id name="ID" column="ID"&gt; &lt;generator class="native"/&gt; &lt;/id&gt; &lt;property name="Chief" column="chief"/&gt; &lt;property name="Name" column="name"/&gt; &lt;property name ="Address" column="address"/&gt; &lt;set name="Recruits" cascade="save-update" inverse="true" lazy="true"&gt; &lt;key&gt; &lt;column name="AssignedOnRecruitmentOffice"/&gt; &lt;/key&gt; &lt;one-to-many class="Recruit"/&gt; &lt;/set&gt; </code></pre> <p></p> <p>And create Repository class with method Insert:</p> <pre><code> public void Insert(Recruit recruit) { using (ITransaction transaction = session.BeginTransaction()) { session.Save(recruit); transaction.Commit(); } } </code></pre> <p>then I try to save new recrui to base:</p> <pre><code> Recruit test = new Recruit(); RecruitmentOffice office = new RecruitmentOffice(); ofice.Name = "test"; office.Chief = "test"; test.AssignedOnRecruitmentOffice = office; test.Name = "test"; test.DateOfBirth = DateTime.Now; RecruitRepository testing = new RecruitRepository(); testing.Insert(test); </code></pre> <p>And have this error</p> <pre><code> GenericADOException could not insert: [OSiUBD.Models.DAO.Recruit][SQL: INSERT INTO Recruits (lastname, name, medicalReport, dateOfBirth, assignedOnRecruitmentOffice) VALUES (?, ?, ?, ?, ?); select SCOPE_IDENTITY()] </code></pre> <p>on session.Save</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
