• 1) SQL Server apparently (based on my tests) already does the "buffer-extension" trick available to mutable strings. Unfortunately, the Extension trick does NOT solve the O(n^2) problem,

    If it supports the "buffer-extension" trick,then why it doesn't solve O(n^2) problem. again , i need to know exactly about O(n^2).

    can you explain it with example? so that i can remember it through my career.

    Does this issue solved in sql2008?

    aaah...i am confusing myself....i think....
