Hello experts.

I have a Sql XMl template and i want to run a search.

//MyCars.XML

<XML version="1.0" encoding="utf-8">
<ROOT xmlns:sql="urn:schemas-microsoft-com:xml-sql">
      <sql:header>
      <sql:param name="id" />
      <sql:param name="brandid" />
      </sql:header>
      <sql:query>
            Select * From IndexCarsXML Where dealer = @id And Brand = @brandid FOR XML AUTO , ELEMENTS
      </sql:query>
</ROOT>
</XML>

I call this Xml file from my Domain.
How can i give results if eg Brandid = null.??

http://localhost/xml/myCars.xml?id=1000&BrandId=10 'returns all Mercedes cars.
http://localhost/xml/myCars.xml?id=1000 'returns nothing , but i want to return all (if brandid = null) then ?

Change:
Select * From IndexCarsXML Where dealer = @id And Brand = @brandid FOR XML AUTO , ELEMENTS

To:
Select * From IndexCarsXML Where dealer = @id And (@brandid Is Null Or Brand = @brandid) FOR XML AUTO , ELEMENTS

Just remember that:
Null <> Null

i ment ,

there is something to check if there are data in the var?

eg.

query = "select mpla mpla "
if @brandid <> "" then query = query & "where Brand = @Brandid"
....

because i have miltiple vars from querystring like (year,model,modeltype etc)

Lets say i have MyCars.XML
(the code presented to u above)

Query: MyCars.XML?id=1&brandid=10&model=evo&year1=2000&year2=2006&.... -->returns all cars with barnd 10 , model like 'evo' from year=2000 to 2006 etc

i may have multiple vars in querystring., or i just have 1 or 2

Query: MyCars.XML?id=1 --> returns all cars

Can i do all that in one XML file , and if yes how?

Something like this perhaps:

Select *
From IndexCarsXML
Where dealer = @id
          And Brand = @brandid
          And Model = @model
          And [Year] In (@Year1, @Year2, ...)
FOR XML AUTO , ELEMENTS

I would like to give a hint.

In asp code i do the following.

id = request("id")
query = "Select * From IndexCarsXML Where Dealer=" & id & " "


if request("brandid") <> "" Then query = query & "and brand = " & request("brandid") & " "
if request("model") <> "" Then query = query & "and model like '%" & request("model") & "%' "
if request("year1") <> "" Then query = query & "and year >= " & request("year1") & " "
if request("year2") <> "" Then query = query & "and year <= " & request("year2") & " "
etc.

Can i do something like that in the XML file?
thanks

No, Xml is just data,  that logic would have to go in the XSLT template file.  But you are better off putting that logic in your SQL query.

Something like this:

Select *
From IndexCarsXML
Where dealer = @id
          And (@brandid = '' Or Brand = @brandid)
          And (@model = '' Or Model = @model)
          And (@Year1 = '' Or [Year] = @Year1)
          And (@Year2 = '' Or [Year] = @Year2)
FOR XML AUTO , ELEMENTS
