    <p>Could someone please help me or get me started with converting this query to an nhibernate queryover query?</p> <pre><code>SELECT Campaign.Id, Location.Name, Location.PrimaryPostcode, Inventory.Section, Campaign.Sov, IFNULL(Contracts.Spend, 0) AS Spend, IFNULL(Contracts.Impressions, 0) AS Impressions, IFNULL(Days, 0) Days, RenewalDate, LastContract.OptIn FROM Contract AS Campaign JOIN Inventory ON Campaign.InventoryId = Inventory.Id JOIN Location ON Inventory.LocationId = Location.Id LEFT OUTER JOIN ( SELECT CampaignId, SUM(RackRate) AS Spend, SUM(Impressions) AS Impressions, 1 + DATEDIFF(Now(), MIN(StartDate)) AS Days, DATE_SUB(MAX(EndDate), INTERVAL 11 Day) AS RenewalDate, MAX(StartDate) AS CurrentOrNextStartDate FROM Contract LEFT OUTER JOIN Creative On Creative.ContractId = Contract.Id LEFT OUTER JOIN CreativeLog On Creative.Id = CreativeLog.CreativeId GROUP BY CampaignId ) AS Contracts ON Campaign.Id = Contracts.CampaignId LEFT OUTER JOIN ( SELECT CampaignId, Id, Optin, StartDate FROM Contract ) AS LastContract ON Campaign.Id = LastContract.CampaignId AND Contracts.CurrentOrNextStartDate = LastContract.StartDate WHERE Campaign.AgencyId = '04ba6b28-a7a0-4448-b21f-9f2b00a4621b' ORDER BY RenewalDate, Location.Name, Inventory.Section </code></pre> <p>I haven't made it past here:</p> <pre><code>_session.QueryOver&lt;Contract&gt;() .Left.JoinQueryOver&lt;Contract&gt;(campaign =&gt; campaign.Contracts).List() </code></pre> <p>Namely because nhibernate is generating an on clause between there two table alias Id == Id when it should be CampaignId == Id. </p> <pre><code>FROM Contract this_ left outer join Contract contract1_ on this_.Id=contract1_.Id </code></pre> <p>Contract's "Contracts" property is a self referencing relationship. It is not 1:1 tho.</p>

Guidance
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.
