Question

I’m very very new to XQUERY/XPATH 🙂 so I could very well be going about this the wrong way. I have a customer object serialized and stored in a database column in the following format.

<Customer xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Addresses>
<AddressBlock>
  <AddressLine1>1234 SomeStreet Ave.</AddressLine1>
  <City>SomeCity</City>
  <State>SomeState</State>
  <Zipcode>SomeZip</Zipcode>
</AddressBlock>
<AddressBlock>
  <AddressLine1>5678 SomeOtherStreet Ave.</AddressLine1>
  <City>SomeOtherCity</City>
  <State>SomeOtherState</State>
  <Zipcode>SomeOtherZip</Zipcode>
</AddressBlock>
</Addresses>
</Customer>

I’m looking for a way to select this record if addressline1 and city in the same addressblock contains certain keywords. I have the following statement that almost does what I’m looking for.

select * 
from users 
where [UserData].exist('/Customer/Addresses/AddressBlock/AddressLine1/text()[contains(upper-case(.),""SOMESTREET"")]')=1
and [UserData].exist('/Customer/Addresses/AddressBlock/City/text()[contains(upper-case(.),""SOMECITY"")]')=1"

My only problem is this statment will also return the record if the first addressblock contains the addressline1 and the second addressblock contains the city.

You have to test both conditions in the same XQuery.

select * 
from users 
where [UserData].exist('/Customer/Addresses/AddressBlock
                         [contains(upper-case(AddressLine1[1]),"SOMESTREET") and 
                          contains(upper-case(City[1]),"SOMECITY")]')=1
