String Search in XQuery
SQL Server 2012
This topic provides sample queries that show how to search text in XML documents.
A. Find feature descriptions that contain the word "maintenance" in the product catalog
SELECT CatalogDescription.query('
declare namespace p1="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/ProductModelDescription";
for $f in /p1:ProductDescription/p1:Features/*
where contains(string($f), "maintenance")
return
$f ') as Result
FROM Production.ProductModel
WHERE ProductModelID=19
In the previous query, the where in the FLOWR expression filters the result of the for expression and returns only elements that satisfy the contains() condition.
This is the result:
<p1:Maintenance
xmlns:p1="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/ProductModelWarrAndMain">
<p1:NoOfYears>10</p1:NoOfYears>
<p1:Description>maintenance contact available through your
dealer or any AdventureWorks retail store.</p1:Description>
</p1:Maintenance>
