    <p><strong>I am making a Report using RDLC. Visual Studio 2010 Ultimate + SQL Server 2012 Express</strong></p> <blockquote> <p><strong>InvoiceID is a String.</strong> This is a query with parameter on a Dataset TableAdapter. I entered this SQL in the Query Builder part of the DataSet.</p> </blockquote> <pre><code>SELECT SequenceNo, InvoiceID, VisitID, CaseNo, WalkinID, Payment, Invoice_date, Status FROM INVOICE WHERE (InvoiceID = @InvoiceID) </code></pre> <p>When I click the Execute Query in the Query Builder, it asks for a value. I enter 20130508-650875. No quotes whatsoever. Then it produces the result I wanted.</p> <p>Now, I'm going to run the program then generate the report.</p> <p>The C# part:</p> <pre><code> INVOICETableAdapter.Fill(dataset.INVOICE, InvoiceID); MessageBox.Show(InvoiceID.ToString()); //just to confirm what value the parameter is getting </code></pre> <p>Now, nothing comes out of the table in my report. I don't know why. The table on my report now only contains the headers of the columns I dragged.</p> <p>I TRIED REMOVING THE ---WHERE--- PART OF THE QUERY AND IT PRODUCED A LOT OF RESULTS!</p> <pre><code>SELECT SequenceNo, InvoiceID, VisitID, CaseNo, WalkinID, Payment, Invoice_date, Status FROM INVOICE //WHERE (InvoiceID = @InvoiceID) </code></pre> <p>Now, I want to ask you guys what could be the reason why does the table in my report go blank when I execute the report with parameters. But if it has no parameters, it produces all results. Could it be the query? </p>

    1. CONevermind, I just used VisitID, which is int, as the parameter. There is really some issue when making a String as a parameter in the Query Builder that I don't really know :)

Querying!

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.
