I have some XML data stored in a varchar(max) column on SQL Server 2005. The data is in the form (FQTN = fully qualified type name):
<?xml version="1.0" encoding="utf-16"?>
<History xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<EntityViews>
<EntityProxy Type="FQTN" Key="386876" />
<EntityProxy Type="FQTN" Key="387981" />
<!-- etc. -->
</EntityViews>
</History>
How can I select Type, Key so that I get a tabular result from the XML data in this column for a single row? The table has an identity primary key named HistoryId.
;with cteCastToXML as (
select CAST(YourColumn as xml) as x
from YourTable
)
select h.ep.value('@Type','varchar(10)') as [Type],
h.ep.value('@Key', 'varchar(10)') as [Key]
from cteCastToXML
cross apply x.nodes('/History/EntityViews/EntityProxy') as h(ep)
