(SQL Server) Creating a New Child Node

Demonstrates how to create a new child in an XML document.

The following XML sample code produces this output:

<abc>
    <xyz>
        <mmm>123</mmm>
    </xyz>
</abc>

CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    -- Important: Do not use nvarchar(max).  See the warning about using nvarchar(max).
    DECLARE @sTmp0 nvarchar(4000)
    DECLARE @xml int
    -- Use "Chilkat_9_5_0.Xml" for versions of Chilkat < 10.0.0
    EXEC @hr = sp_OACreate 'Chilkat.Xml', @xml OUT
    IF @hr <> 0
    BEGIN
        PRINT 'Failed to create ActiveX component'
        RETURN
    END

    EXEC sp_OASetProperty @xml, 'Tag', 'abc'

    -- Create a new child  with no content 
    -- and return the newly created child node:
    DECLARE @childNode int

    EXEC sp_OAMethod @xml, 'NewChild', @childNode OUT, 'xyz', ''

    -- Create a child under childNode, but instead call
    -- NewChild2 which doesn't return the newly created child node:
    EXEC sp_OAMethod @childNode, 'NewChild2', NULL, 'mmm', '123'

    EXEC @hr = sp_OADestroy @childNode

    EXEC sp_OAMethod @xml, 'GetXml', @sTmp0 OUT
    PRINT @sTmp0

    EXEC @hr = sp_OADestroy @xml
