Hi, i am reasonably proficient with SQLServer, but i'm not a DBA so i'm not sure how to approach this.
I have an XML chunk stored in an ntext
column. Due to it being a legacy database and the requirements of the project i cannot change the table (yet). This is an example of the data i need to manipulate:
<XmlSerializableHashtable xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Entries>
<Entry>
<key xsi:type="xsd:string">CurrentYear</key><value xsi:type="xsd:string">2010</value>
</Entry>
<Entry>
<key xsi:type="xsd:string">CurrentMonth</key><value xsi:type="xsd:string">4</value>
</Entry>
</Entries>
</XmlSerializableHashtable>
each row will have a chunk like this, but obviously with different keys/values in the XML. Is there any clever way i can parse this XML in to a name/value pairs style view? Or should i be using SQLServer's XML querying abilities even though it isn't an XML column? If so, how would i query a specific value out of that column?
(Note: adding a computed XML column on the end of the table is a possibility, if that helps).
Thanks for any assistance!
