    <p>I need to execute runtime defined SQL queries on a database and show results on a datagrid. I'm using this code to query the database. It should return an IEnumerable of runtime defined objects of customType</p> <pre><code>List&lt;dynamic&gt; result; using (context = new DataContext(ConnStr)) { IEnumerable enumerable = context.ExecuteQuery(customType, query); result = enumerable.Cast&lt;dynamic&gt;().ToList(); } </code></pre> <p>The sample customType and Query I'm using are as follows</p> <p>CustomType: CustomType is created at runtime and it's equivalent to:</p> <pre><code>class customType { public int Id {get; set;} } </code></pre> <p>Query: </p> <pre><code>Select id from TestTable </code></pre> <p>What ExecuteQuery is returning a list of customType objects that id is 0 in all of them. I did the same with context.ExecuteQuery and this time I defined my customType in compile time (&lt;> operator does not work with Type instances), and it worked as expected and returned list of legit ids. I checked msdn page and find this interesting description:</p> <blockquote> <p>Public method <em>ExecuteQuery(String, Object[])</em> Executes SQL queries directly on the database <strong>and returns objects</strong>. </p> <p>Public method <em>ExecuteQuery(Type, String, Object[])</em> Executes SQL queries directly on the database.</p> </blockquote> <p>Any help is appreciated. </p> <p>Update: TestTable definition in my SQL Server database:</p> <pre><code>CREATE TABLE [dbo].[TestTable]( [Id] [int] IDENTITY(1,1) NOT NULL, [StartDate] [datetime] NOT NULL, [BasePath] [varchar](512) NOT NULL, CONSTRAINT [PK_TestTable] PRIMARY KEY CLUSTERED ( [Id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] </code></pre> <p>(if there's any syntax error it's a typo)</p>

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.
