If you're using a recent version of SQL Server, there's a new column data type (XML). You can apply xpath to it, making querying the column much easier. Instead of trying to store the XML as a string in your DB, I'd suggest you actually store it as XML, and treat it as XML. There is a learning curve. You'll need to be familiar with XPATH, but it's not rocket science. an example: <pre><code>SELECT Id, PartitionMonth, EmailAddress, AcquisitionCodeId, FieldValues.value(' declare namespace s="http://domain.com/FieldValues.xsd"; data(/s:FieldValues/s:item/@value)[1]', 'varchar(200)') FROM Leads.Leads WITH (NOLOCK) WHERE Id = 190708 </code></pre> Another example retrieving values by key: <pre><code>SELECT r.EmailAddress, ar.Ip, ar.DateLog, ar.FieldValues.value(' declare namespace s="http://domain.com/FieldValues.xsd"; data(/s:FieldValues/s:item[@key="First Name"]/@value)[1]', 'varchar(20)') FirstName, ar.FieldValues.value(' declare namespace s="http://domain.com/FieldValues.xsd"; data(/s:FieldValues/s:item[@key="Last Name"]/@value)[1]', 'varchar(20)') LastName FROM Records.Records r WITH (NOLOCK) JOIN Records.AcquisitionRecords ar WITH (NOLOCK) ON r.Id = ar.Id WHERE ar.AcquisitionCodeId IN (19, 21, 30, 34, 36) AND ar.DateLog BETWEEN '1-mar-09' AND '31-mar-09' </code></pre> A good place to get started on XML in SQL Server <a href="http://msdn.microsoft.com/en-US/library/ms189887(v=sql.90).aspx" rel="nofollow">http://msdn.microsoft.com/en-US/library/ms189887(v=sql.90).aspx</a>

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.
