Hello everybody,
I need some help with NHibernate here. I have an experience with Hibernate (for java) but now ( in .NET) I'm experiencing trouble that I'm not being able to solve :s
When I try to save some classes (using save, saveorupdate, saveorupdatecopy) I get the following error message:
Code:
SQL insert, update or delete failed (expected affected row count: 1, actual affected row count: 0). Possible causes: the row was modified or deleted by another user, or a trigger is reporting misleading row count.
I looked for it in google and I found things related to sets in mappings. Like when you try to persist a children class without its parent. But I do not have this case in my mapping.
Here goes some of the mappings of classes that give me the error:
Quote:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.0">
<class name="SGEIntegracao.Entidade.HistoricoAfericao, SGEIntegracao" table="T35_Historico_Afericao">
<composite-id>
<key-property name="NumeroSerieProcessador" column="T35_Numero_Serie_Processador" type="String" />
<key-property name="Faixa" column="T35_Faixa" type="String" />
<key-property name="DataAfericao" column="T35_Data_Afericao" type="DateTime" />
<key-property name="TipoAfericao" column="T35_Tipo_Afericao" type="Int32" />
</composite-id>
<property name="DataValidade" column="T35_Data_Validade" type="DateTime" />
<property name="Inmetro" column="T35_Inmetro" type="String" />
<property name="LacreInmetro" column="T35_Numero_Serie_Inmetro" type="String" />
<property name="NumeroSerieInmetro" column="T35_Lacre_Inmetro" type="String" />
</class>
</hibernate-mapping>

</id>
<property name="Nome" column="Nome" type="String" />
<property name="Observacao" column="Obse" type="String" />
<property name="Fabricante" column="Fabr" type="String" />
<property name="Modelo" column="Mode" type="String" />
<property name="Tipo" column="Tipo" type="String" />
</class>
</hibernate-mapping>
For other classes persisted in the same session, everything works fine. I'm using the same session because I need to use the same transaction for many persistences.
Anything you could do for me? thanks
