TSQL XML Parsing

Question

I have an XML block that I am sending to my stored procedure.

<vehicles>
<licensePlate>ABC123</licensePlate>
<vehicle>
  <model>Ford</model>
  <color>Blue</color>
  <carPool>
     <employee>
        <empID>111</empID>
     </employee>
     <employee>
        <empID>222</empID>
     </employee>
     <employee>
        <empID>333</empID>
     </employee>
  </carPool>
</vehicle>
</vehicles>

I then use a select statement to parse out the data that I need from this XML block.

INSERT INTO licensePlates (carColor, carModel, licensePlate, empID, dateAdded) 
    SELECT  ParamValues.x2.value('color[1]', 'VARCHAR(100)'),
            ParamValues.x2.value('model[1]', 'VARCHAR(100)'),
            ParamValues.x2.value('../licensePlate[1]', 'VARCHAR(100)'),
            @empID,
            GETDATE()
    FROM   @xmlData.nodes('/vehicles/vehicle') AS ParamValues(x2)

I need to store the XML contained within the tag <carPool> into a column in this table.

So I'm getting this XML block, and need a piece of that to not be parsed and just go directly to the table:

<carPool>
     <employee>
        <empID>111</empID>
     </employee>
     <employee>
        <empID>222</empID>
     </employee>
     <employee>
        <empID>333</empID>
     </employee>
  </carPool>

How can I go about doing this?

This is an example of what the inserted record would look like.

Answer 1

Assuming your stored procedure has a parameter called @Input XML , you could use this code:

INSERT INTO dbo.YourTable(XmlColumn)
   SELECT @input.query('/vehicles/vehicle/carPool')

That should select the <carPool> XML tag and insert it into the XML column of your table.

Answer 2

I think this is what you are looking for:

SELECT  ParamValues.x2.value('color[1]', 'VARCHAR(100)'),
        ParamValues.x2.value('model[1]', 'VARCHAR(100)'),
        ParamValues.x2.value('../licensePlate[1]', 'VARCHAR(100)'),
        @empID,
        GETDATE()
        , carPoolMembers = x2.query('./carPool')
FROM   @xmlData.nodes('/vehicles/vehicle') AS ParamValues(x2)    

Answer 3

You can insert the node directly

INSERT INTO licensePlates (carColor, carModel, licencePlate, empId, dateAdded, carPoolMembers) 
    SELECT  ParamValues.x2.value('color[1]', 'VARCHAR(100)'),
            ParamValues.x2.value('model[1]', 'VARCHAR(100)'),
            ParamValues.x2.value('../licensePlate[1]', 'VARCHAR(100)'),
            @empID,
            GETDATE(),
            ParamValues.x2.query('./carPool')
    FROM   @xmlData.nodes('/vehicles/vehicle') AS ParamValues(x2)
