    <p>I am facing a problem while calling procedure using named query in nhibernate. I have a procedure which accept three parameters, first one is varchar(max) which is actually a guid list, second is varchar(50) and third one is bit type.</p> <p>I have using following procedure in C# using named query Nhibernate</p> <pre><code> var Customerbalance = Session.GetNamedQuery("ar_tARCustomer_ReadAccount_ForBalanceDetail_New") .SetParameter("CustomerList", "'''bced443a-ce86-4675-bca6-ae5646ad9c2e'' , ''bced443a-ce86-4675-bca6-ae5646ad9c2e'''") .SetParameter("AsOfDate", "10/1/2012") .SetParameter("PostedOnly", PostedOnly) .SetResultTransformer(new AliasToBeanResultTransformer(typeof(tARCustomer))).List&lt;tARCustomer&gt;(); </code></pre> <p>And following code is for .hbm.xml file </p> <pre><code>&lt;sql-query name="ar_tARCustomer_ReadAccount_ForBalanceDetail_New" callable="true"&gt; &lt;!--&lt;query-param name="CustomerList" type="VARCHAR(max)" /&gt; &lt;query-param name="AsOfDate" type="string" /&gt; &lt;query-param name="PostedOnly" type="bool" /&gt;--&gt; &lt;return class="tARCustomer"&gt; &lt;/return&gt; exec ar_tARCustomer_ReadAccount_ForBalanceDetail_New @CustomerList=:CustomerList, @AsOfDate=:AsOfDate, @PostedOnly=:PostedOnly &lt;/sql-query&gt; </code></pre> <p>When I debug the code it gives error:</p> <blockquote> <p>Conversion failed to character string to uniqueidentifier</p> </blockquote> <p>When I passed these same parameters in sql server it runs successfully.</p> <p>Here in C#, I had tried all type of combination for passing parameter to procedure using NHibernate but it always crashed.</p>

    1. COI would say that the problem is when trying to transform the result of the query. First, try with a bean class that uses string instead of guid. If that works, you should check that the result is a legitimate guid http://guid.us/Test/GUID (not null, truncated, no leading or trailing spaces)

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.
