SQL Server 2008 R2 trigger identity column

Question

I need to create a trigger to add a record to second table.

• First table : tab_esami
• Second table : tab_valutazioni

I create this trigger :

CREATE TRIGGER [dbo].[NewTrigger]
ON [dbo].[tab_esame]
AFTER INSERT
AS
BEGIN
    /* Trigger action goes here. */
    SET IDENTITY_INSERT TAB_VALUTAZIONI ON

    INSERT INTO tab_valutazioni(tab_utenti_id, nume_colesterolo,
                                nume_hdl, nume_ldl, nume_trigliceridi,
                                nume_glicemia, data_insert)
        SELECT 
            id_paziente, colesterolo_totale,
            hdl, ldl, trigliceridi,
            glicemia, data_esame
        FROM 
            INSERTED
END
GO

But when I try to insert a record into tab_esami I get an error :

Error_ON_insert

Can you help me?

The id column for tab_valutazioni is 'ID' and it is a primary key with autoincrement properties..

Thanks

If you want this code to work properly you should set Identity Column. See this.
