    <p>I am trying to display all records that match the last name entered into a textbox. This requires an INNER JOIN on the "volID" column because there are 2 tables.</p> <pre><code>&lt;asp:TextBox ID="lName" runat="server"&gt;&lt;/asp:TextBox&gt; &lt;asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true" Visible="true"&gt;&lt;/asp:GridView&gt; &lt;asp:linkButton ID="btnSubmit" runat="server" onclick="btnSubmit_Click" /&gt; </code></pre> <p>Code behind:</p> <pre><code> protected void btnSubmit_Click(object sender, EventArgs e) { GridView1.DataSource = new Select("*") .From(PastAwardName.Schema) .InnerJoin(PastAwardName.VolIDColumn, PastAwardType.VolIDColumn) .Where(PastAwardName.Columns.LName).IsEqualTo(this.lName.Text) .ExecuteReader(); GridView1.DataBind(); } </code></pre> <p>I tried to do this from and example on Subsonics site but cannot get it working. Geeting the error below.</p> <pre><code>Server Error in '/' Application. ________________________________________ The objects "dbo.pastAwardNames" and "dbo.pastAwardNames" in the FROM clause have the same exposed names.

    1. COWhere/how is the second table defined? It appears from the error that it's trying to join the same table to itself.

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.
