NHibernate在'？'附近撤回不正确的语法

Question

当我使用Hibernate时，我收到错误"Incorrect syntax near '?'"。

我的代码如下：

        criteria.Add(Restrictions.InG("OrgUnit", orgUnits));

        criteria.SetProjection(
            Projections.ProjectionList()
                        .Add(Projections.GroupProperty("OrgUnit"), "OrgUnit")
                        .Add(Projections.GroupProperty("IncidentStatus"), "IncidentStatus")
                        .Add(Projections.SqlGroupProjection(
                            "Year(IncidentDate) as Year",
                            "Year(IncidentDate)",
                            new[] { "Year" },
                            new[] { NHibernateUtil.Int32 }))
                        .Add(Projections.SqlGroupProjection(
                            "Month(IncidentDate) as Month",
                            "Month(IncidentDate)",
                            new[] { "Month" },
                            new[] { NHibernateUtil.Int32 }))
                        .Add(
                            Projections.Count(
                                Projections.Conditional(
                                    Restrictions.Where<SheIncidentEvent>(f => f.IsReportable == true),
                                    Projections.Constant(1),
                                    Projections.Constant(0))), 
                                    "TotalReportable")
                        .Add(
                            Projections.Sum(
                                Projections.Conditional(
                                    Restrictions.Where<SheIncidentEvent>(f => f.IsReportable == true), 
                                    Projections.Constant(1), 
                                    Projections.Constant(0))),
                                    "RiddorReportable")
                        .Add(
                            Projections.Sum(
                                Projections.Conditional(
                                    Restrictions.Where<SheIncidentEvent>(f => f.IsLostTime == true),
                                    Projections.Constant(1),
                                    Projections.Constant(0))),
                                    "LostTime")
                        .Add(Projections.Sum("LostTimeActual"), "TotalDaysLost")
                        .Add(
                            Projections.Sum(
                                Projections.Conditional(
                                    Restrictions.Where<SheIncidentEvent>(f => f.IsNearMiss == true),
                                    Projections.Constant(1),
                                    Projections.Constant(0))),
                                    "NearMiss"))
                .SetResultTransformer(Transformers.AliasToBean(typeof(SheIncidentEventBreakdownByDateCounter)));

这会产生以下异常：

[ SELECT this_1_.SheOrgUnit_Id as y0_, this_.IncidentStatus_id as y1_, Year(IncidentDate) as Year, Month(IncidentDate) as Month, count((case when this_.IsReportable = ? then ? else ? end)) as y4_, sum((case when this_.IsReportable = @p0 then @p1 else @p2 end)) as y5_, sum((case when this_.IsLostTime = @p3 then @p4 else @p5 end)) as y6_, sum(this_.LostTimeActual) as y7_, sum((case when this_.IsNearMiss = @p6 then @p7 else @p8 end)) as y8_ FROM tblSheIncidentEvent this_ inner join tblSheModule this_1_ on this_.SheModule_id=this_1_.Id WHERE this_1_.SheCustomer_id = @p9 and this_1_.IsArchive = @p10 and this_1_.IsActive = @p11 and this_1_.SheOrgUnit_Id in (@p12) GROUP BY this_1_.SheOrgUnit_Id, this_.IncidentStatus_id, Year(IncidentDate), Month(IncidentDate) ]

任何人都可以解释这是什么问题，以及如何解决它？
