How can I provide values for non-grouped columns in NHibernate?
- by ddc0660
I have a criteria query:
Session.CreateCriteria<Sell043Report>()
.SetProjection(.ProjectionList()
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.location))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.agent))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.cusip))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.SettlementDate))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.salePrice))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.foreignFx))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.batchNumber))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.origSaleDate))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.planName))
.Add(LambdaProjection.GroupProperty<Sell043Report>(r => r.dateTimeAdded))
.Add(LambdaProjection.Sum<Sell043Report>(r => r.shares))
.Add(LambdaProjection.Sum<Sell043Report>(r => r.netMoney))
.Add(LambdaProjection.Sum<Sell043Report>(r => r.grossMoney))
.Add(LambdaProjection.Sum<Sell043Report>(r => r.taxWithheld))
.Add(LambdaProjection.Sum<Sell043Report>(r => r.fees)))
.List<Sell043Report>();
that generates the following SQL:
SELECT
this_.location as y0_,
this_.agent as y1_,
this_.cusip as y2_,
this_.SettlementDate as y3_,
this_.salePrice as y4_,
this_.foreignFx as y5_,
this_.batchNumber as y6_,
this_.origSaleDate as y7_,
this_.planName as y8_,
this_.dateTimeAdded as y9_,
sum(this_.shares) as y10_,
sum(this_.netMoney) as y11_,
sum(this_.grossMoney) as y12_,
sum(this_.taxWithheld) as y13_,
sum(this_.fees) as y14_
FROM
MIS_IPS_Sell043Report this_
GROUP BY
this_.location,
this_.agent,
this_.cusip,
this_.SettlementDate,
this_.salePrice,
this_.foreignFx,
this_.batchNumber,
this_.origSaleDate,
this_.planName,
this_.dateTimeAdded
however the Sell043Report table has additional columns than those listed in the SELECT statement so I'm receiving this error when attempting to get a list of Sell043Reports:
System.ArgumentException: The value "System.Object[]" is not of type "xyz.Sell043Report" and cannot be used in this generic collection.
I suspect the problem is that I'm not selecting all of the columns for a Sell043Report and so it doesn't know how to map the dataset to the object. I'm trying to achieve something like this:
SELECT
this_.location as y0_,
this_.agent as y1_,
this_.cusip as y2_,
this_.SettlementDate as y3_,
this_.salePrice as y4_,
this_.foreignFx as y5_,
this_.batchNumber as y6_,
this_.origSaleDate as y7_,
this_.planName as y8_,
this_.dateTimeAdded as y9_,
sum(this_.shares) as y10_,
sum(this_.netMoney) as y11_,
sum(this_.grossMoney) as y12_,
sum(this_.taxWithheld) as y13_,
sum(this_.fees) as y14_,
'' as Address1,
'' as Address2 // etc
FROM
MIS_IPS_Sell043Report this_
GROUP BY
this_.location,
this_.agent,
this_.cusip,
this_.SettlementDate,
this_.salePrice,
this_.foreignFx,
this_.batchNumber,
this_.origSaleDate,
this_.planName,
this_.dateTimeAdded
How can I do this using NHibernate?
