  Hi,

  I need to know the performance downsides of using For XML clause. Does SQL Server prepare an XML representation of data every time a query is executed ?? Is there any way of tuning the performance ??

  Also, which one is the most fastest  ??

  1. For XML Auto

  2. For XML Raw

  3. For XML Explicit

  Thanks in advance.

  Regards,

  Hatim Ali.
